Employee Benefits & Compensation

What counts as an employee benefit?

An employee benefit is anything of value an employer provides in exchange for your work other than wages: contributions to a retirement plan, the employer's share of insurance premiums, paid time off, equity, and a long tail of smaller items from tuition help to a transit pass. Together with salary and bonus they make up your total compensation, which is the honest unit for comparing two jobs.

The reason to think in that unit rather than in salary is not that benefits are large, though they are. It is that salary is the component least likely to differ. Base pay for a given role in a given market is benchmarked against survey data that both sides can see, so two competing offers tend to land close together. The retirement match, the share of the health premium the employer covers, how much leave you can actually take, and whether there is equity are none of those things. They vary enormously between employers, they are hard to compare because they are quoted in different units, and they compound: a match is invested for decades, and a cheaper family premium is a monthly difference that recurs.

It helps to sort the package into four families, because each behaves differently and each has its own decision points.

• Retirement. The workplace plan, the employer's contribution to it, and the schedule on which that contribution becomes yours. Mostly a set of elections you make once and revisit annually.
• Health and welfare. Medical, dental and vision coverage, the accounts that pair with them, and the insurance that pays if you cannot work or if you die. Chosen in a window, then generally locked for the year.
• Time. Paid time off, holidays, sick leave, parental leave, and the unpaid job protection federal law provides. Almost entirely employer policy rather than legal entitlement.
• Compensation beyond salary. Bonus, commission, equity, and at higher pay levels, deferred compensation. The part with the most money at stake and the least standardization.

One caution about the total figure itself. When an employer prints a total compensation statement, it is reporting employer cost, and employer cost is not the same as value to you. It usually includes the payroll taxes the employer would owe on any job, which are not a benefit of working there in particular. And it values your health coverage at what the employer pays, which overstates its worth to someone who would have bought cheaper coverage. A retirement match, by contrast, is worth approximately its face value, because it is cash going into an account with your name on it. The components are worth pricing separately rather than accepting a single number.

Where does the money go before you see it?

Your paycheck runs through a fixed order of operations, and knowing the order explains most of the gap between the salary you negotiated and the amount that lands in your account. Gross pay comes first. Then certain benefit elections are subtracted before tax is calculated. Then income tax withholding is applied to what remains. Then anything post-tax comes out.

The middle step is the one worth understanding, because it is where benefits stop being a cost and start being a discount. A pre-tax election reduces the wages your tax is computed on, so its real cost to you is less than its sticker price. Money you put into a traditional 401(k), most health premiums paid through the employer's plan, contributions to a health savings account or flexible spending account made through payroll, and commuter benefits all work this way. If you set aside a dollar of pay through one of these, your take-home falls by less than a dollar, and the size of the gap depends on your tax rate.

Payroll taxes follow a slightly different base, and the exception is the one that matters most. Health premiums, spending-account contributions and commuter benefits escape Social Security and Medicare tax as well as income tax. A traditional 401(k) deferral does not. It defers income tax only, and Social Security and Medicare tax are still charged on it, so a deferral saves you your income tax rate rather than your income tax rate plus payroll tax. Anyone sizing a contribution on the assumption that it avoids both is overstating the saving.

That mechanism is also why the wage figure in Box 1 of your Form W-2 is smaller than what you think you earn, and why it does not match the number on your offer letter. It is deliberately not your gross pay. It is gross pay reduced by the pre-tax elections and increased by taxable non-cash items, such as the imputed income on employer life cover described below. It is also why Box 1 is usually smaller than the Social Security and Medicare wage boxes beside it, which is a feature rather than a discrepancy to be reconciled.

Not every election is pre-tax, and the exceptions matter. Roth contributions to a workplace plan come out after tax by design, which is the whole point of them. Contributions toward an employee stock purchase plan, a payroll-funded scheme for buying company stock at a discount, are after-tax. And, as the sections below explain, some insurance premiums are worth paying after tax on purpose, because doing so changes how the benefit is taxed if you ever claim it.

How much income tax is withheld is set by the Form W-4 you filed, and the mechanics of that form, of payroll taxes, and of the safe harbors that keep you out of underpayment penalties belong to our guide to taxes. The point to carry into the rest of this page is narrower: your benefit elections are one of the two levers that determine your take-home pay, and the only one most people never touch.

What should I do with the workplace retirement plan?

Contribute at least enough to collect the entire employer match, then treat everything else as a separate question. A match is money the employer adds to your account based on what you put in, typically expressed as a formula like a dollar for each dollar you contribute up to a set percentage of your pay, or fifty cents on the dollar up to a higher percentage. Contributing less than the full match declines part of your compensation, which is why it sits at the top of almost every version of the financial order of operations, ahead of paying down expensive debt.

Read the formula rather than the headline. "Six percent match" is ambiguous between an employer that adds six percent of your pay when you contribute six, and one that adds three when you contribute six. Some formulas are capped in dollars rather than percentages. Some are calculated per pay period rather than annually, which means front-loading your contributions early in the year can cause you to hit the annual limit in October and miss the match for the remaining pay periods, unless the plan has a true-up provision that catches it. That last detail costs real money and appears nowhere except the plan document.

Vesting: when the employer's money becomes yours

Vesting is the waiting period an employer attaches to money it contributes. Until a contribution vests it can be taken back; once it vests it is yours whether you stay, quit, or are fired. Two shapes are common. Cliff vesting hands over everything at once on a date, so nothing is yours the day before and all of it is the day after. Graded vesting transfers ownership in installments, such as twenty percent a year.

Three facts do most of the work here. Your own contributions are always fully vested immediately, along with everything they earn; only the employer's money can carry a schedule. Federal law caps how slow that schedule may be, at a three-year cliff or six-year graded vesting, and since 2007 that cap has applied to all employer contributions to a defined contribution plan rather than only to matching contributions. And a plan may always be more generous than the maximum, with contributions under a traditional safe harbor design vesting immediately, so the only way to know your own schedule is to read your summary plan description, the plain-language booklet the plan is legally required to give you setting out its terms.

The practical consequence is that a vesting date is a real, knowable number in a job change. If you are eleven months into a three-year cliff, leaving now costs you every employer dollar contributed so far, and that figure is on your statement. It belongs in the comparison with a new offer, alongside the salary, rather than being noticed afterwards.

The elections you actually control

Most plans created in recent years must enroll new employees automatically, at a default contribution rate that escalates each year unless you opt out. Automatic enrollment is a good default and it is not a recommendation: the default rate was chosen to be low enough that few people object to it, and on many plans it starts below the level that captures the full match. Treating it as advice is how people contribute for years at a rate nobody chose.

Beyond the rate, you choose whether contributions go in pre-tax or as Roth, and you choose investments from the menu the employer selected. The pre-tax versus Roth question turns on your tax rate now against your tax rate when the money comes out, and our retirement planning guide works through it, along with contribution limits and what happens to the account when you change jobs. The investment menu is worth a separate look, because its cost is yours: plan expenses come out of participant accounts in most plans, a federal disclosure exists specifically to reveal what each fund and each service provider is paid, and the difference between a low-cost index option and an expensive actively managed one compounds over a career. Our investing guide covers how much.

The 401(k) is the most common workplace plan, and it has close relatives that work on the same chassis with their own quirks: the 403(b) for public schools and nonprofits, the 457(b) for state and local government, and the Thrift Savings Plan for federal employees and servicemembers. A smaller number of employers, concentrated in government and older unionised industries, still offer a defined benefit pension, which promises a monthly amount for life calculated from a formula rather than an account balance you manage. Pensions have vesting schedules too, and theirs are usually longer.

How do I choose between the health plans I'm offered?

Compare the total you would pay in a year under each plan, not the premium. The total is the premium you pay through payroll, plus what you would spend on care before the plan starts paying in full, and it is bounded above by the plan's out-of-pocket maximum. That gives you two numbers per plan worth knowing: the best case, where you use almost no care and pay only premiums, and the worst case, where you pay premiums plus the full out-of-pocket maximum. Comparing those two pairs answers the question far better than the monthly figure does, and it frequently reverses the ranking, because the plan with the highest premium often has the lowest worst case.

The mechanics behind those numbers, meaning how deductibles, coinsurance and out-of-pocket maximums fit together and what distinguishes an HMO from a PPO or an EPO, are covered in our guide to insurance and risk. What that guide does not cover, because it is specific to being an employee, is the rest of this section.

The employer's contribution differs by plan and by tier, and this is the most under-examined number in the whole exercise. Employers commonly cover a large share of the premium for the employee and a much smaller share for dependents, and the split can differ between the plans on offer. The consequence is that adding a spouse or children can cost wildly different amounts depending on which plan you pick, and that a household with two working adults should price both employers' plans in every combination rather than defaulting to one. Putting each spouse on their own employer's plan and the children on whichever covers dependents more cheaply is often the least expensive answer, and it is rarely the arrangement people fall into by habit.

The window is the employer's, and it is short. Employer open enrollment usually runs for a couple of weeks in the autumn, but no law sets the dates: they come from the plan document, which is why they differ between employers and why a spouse's window may not line up with yours. Miss it and you generally wait a year, unless you have a qualifying life event such as marriage, divorce, a birth or adoption, or losing other coverage.

One more decision sits underneath the plan choice, and it is the subject of the next section: whether to take a high deductible plan in order to use a health savings account, and which spending accounts you are then eligible for.

HSA, health FSA, dependent care FSA: which can I use?

These are three different accounts with different rules, and the first thing to know is that one of them can disqualify you from another. All three let you pay certain costs with money that was never taxed, which is a real discount at your marginal rate. Beyond that they diverge sharply on who owns the money, whether it survives the year, and whether it survives the job.

A health savings account is available only if you are covered by a qualifying high deductible health plan and have no other disqualifying coverage. It is yours: the money does not expire, it can be invested, and it goes with you when you change employers. Our glossary entry covers the eligibility tests and the reason it is the most tax-favored account most people have access to.

A health flexible spending account is close to the opposite. The plan belongs to the employer, you elect an amount before the year begins, the election is generally locked for the whole year, and money left unspent is forfeited unless the employer offers one of two limited reliefs: a carryover of a capped amount into the next year, or a grace period of up to two and a half months. A plan may offer one of those or neither, and is not permitted to offer both.

The health FSA does have one genuine advantage over every other account here, and it is worth knowing because it is invisible from the outside: the full amount you elected is available to you from the first day of the plan year, before you have contributed it. Someone who elects an amount in January, has a large expense in February, and leaves the job in March may be reimbursed for far more than they put in. The dependent care FSA works the opposite way, reimbursing only what has actually been contributed so far, which is a difference that surprises parents who expected the two to behave alike.

The interaction that costs people a year of eligibility

Being covered by a general-purpose health FSA is disqualifying coverage for HSA purposes, because it can pay the same medical expenses. Enroll in one and you cannot contribute to an HSA for those months. Three details make this worse than it sounds. A spouse's general-purpose health FSA disqualifies you as well if it can reimburse your expenses, even though you never elected anything. A carryover or grace period from last year's FSA can extend the block into the following plan year. And eligibility is tested month by month, so the loss is counted in months rather than being all or nothing.

There is a designed solution, and employers that offer a high deductible plan often provide it: a limited-purpose FSA, confined to categories such as dental and vision care, does not disqualify you, so it can be paired with an HSA. The dependent care FSA is a separate account for childcare and similar costs and has no effect on HSA eligibility at all.

One route to a mid-year change is closed to the health FSA entirely, and the distinction is worth getting right. When a benefit's price or availability shifts during the year, employees can often adjust that election, but the regulation excludes health FSAs from those rules outright. A life event such as a marriage, a birth or a change in employment can still permit a change to a health FSA if the plan allows one. What never permits a change is simply realizing you elected too much, so estimate conservatively.

The dependent care FSA also competes with a tax credit for the same expenses, and which one leaves a household better off depends on income and on how many children have qualifying costs. You cannot use the same dollar of expense twice. That comparison is worked through on our taxes guide, and the current contribution ceilings for all of these accounts change most years and are carried on the glossary pages linked above rather than printed here.

What does the employer cover if I get sick, hurt, or die?

Most employers provide some life insurance and some income protection, usually at little or no cost to you and usually without a medical exam. That combination makes group coverage the right place to start and a poor place to stop, because the same features that make it easy to get, meaning standard terms and no underwriting, also make it narrower than individually purchased cover and tie it to the job.

Group life insurance

Employer-provided life insurance is typically term coverage set as a multiple of salary, often one or two times, with the option to buy additional coverage for yourself and sometimes for a spouse or children. Three characteristics define it. It is generally guaranteed issue up to a limit, so it is available to people who would struggle to buy cover individually. It is priced as a group rather than on your own health, which makes it cheap if you are in poor health and sometimes more expensive than an individual policy if you are young and healthy. And it ends when the job does, leaving at most a conversion right that must usually be exercised within weeks and at a substantially higher price.

There is one tax wrinkle that shows up on your pay stub and confuses people. The first $50,000 of employer-provided group term life is excluded from your income. Coverage above that produces imputed income: a taxable amount added to your wages for cover you never received in cash. The amount is not what your employer actually paid. It is calculated from a uniform table set by the IRS, which can be higher or lower than the true cost and which rises steeply with age, reduced by anything you paid toward the cover yourself. It is why a line for a benefit you thought was free appears in your taxable wages, and why the amount grows as you get older even though the coverage has not changed.

The practical question is whether the multiple of salary is enough, and for anyone with dependants or debt it frequently is not. Our insurance guide works through how much coverage a household needs and why an individually owned policy, which does not end when the job does, usually carries the load for people who need substantial cover.

Group disability insurance

Disability insurance replaces part of your income if illness or injury stops you working, and it protects the asset almost nobody thinks to insure, which is the ability to earn for the rest of a career. Employers commonly provide short-term coverage for the first weeks or months and long-term coverage after that. Group long-term disability is inexpensive, usually requires no medical questions, and is the correct starting point.

Two things about it are routinely misread. The replacement percentage is applied to straight-time base pay in nearly all plans, according to federal survey data, which excludes overtime, bonus and commission, so anyone whose income is materially variable is far more exposed than the headline percentage suggests. And where the employer paid the premium the benefit is taxable, so a policy quoting sixty percent of gross pay puts materially less than sixty percent of gross in the bank. Compare the after-tax figure against what you actually spend rather than reading the headline percentage. Group policies also commonly apply a friendlier definition of disability for an initial period and a stricter one afterwards, which is a detail found in the certificate rather than the benefits brochure.

Group coverage also stops at the employer's door. It generally ends when you leave, it is rarely portable, and its caps bind hardest on the highest earners, which is the group with the most income to protect. An individually owned policy is the usual answer for anyone whose group coverage would leave a real gap, and it has to be bought while you are healthy enough to qualify.

What time off am I entitled to?

In the United States, paid time off is almost entirely an employer policy rather than a federal legal entitlement. There is no federal requirement to provide paid vacation, paid holidays, or paid sick leave. What federal law does provide is unpaid, job-protected leave in defined circumstances, and that distinction is the single most misunderstood thing in this part of a benefits package.

The Family and Medical Leave Act provides unpaid leave. It gives eligible employees up to twelve workweeks in a twelve-month period for the birth of a child or a placement by adoption or foster care, to care for a spouse, child or parent with a serious health condition, or for their own serious health condition, with a longer entitlement for caring for a servicemember. What you get is the right to return to the same or an equivalent job, and the continuation of your group health coverage on the same terms as if you had kept working. What you do not get is a paycheck.

Eligibility has three parts, and the third is the one that is usually dropped when the rule is repeated. Your employer must have at least fifty employees within seventy-five miles of your worksite, which is a different and narrower test than having fifty employees overall. You must have worked for that employer for at least twelve months. And you must have worked at least 1,250 hours in the preceding twelve months, which is roughly twenty-four hours a week and which many part-time employees do not meet. Someone at a small or geographically scattered employer may have no FMLA rights at all.

Two details catch people at the end of the leave rather than the beginning. Your own share of the health premium generally remains due while you are away, which has to be paid from somewhere during unpaid weeks. And because the employer keeps paying its share, if you do not return afterwards it is generally entitled to recover the premiums it paid during the unpaid portion of the leave. That recovery right has two statutory exceptions, and they cover the commonest case: the employer cannot reclaim the premiums if you are unable to return because the serious health condition continues or recurs, or for other reasons genuinely beyond your control.

Three separate things commonly get confused with FMLA, and any of them can run at the same time as it. An employer may have its own paid parental or medical leave policy, which is a benefit rather than an entitlement and varies enormously. A number of states operate their own paid family and medical leave programs, funded by payroll contributions and paying a portion of wages, which exist in some states and not in others and which differ in who is covered and for how long. And employer-provided short-term disability insurance may replace income during a medical leave, including recovery from childbirth, which is why the paperwork for a parental leave often involves a disability claim that surprises people.

Two smaller points are worth checking in your own handbook. Whether unused paid time off is paid out when you leave is a matter of state law and employer policy rather than federal law, and the answer varies. And whether unused days carry over or expire at year end determines whether a large balance is an asset or something to use before December.

How does equity compensation actually work?

Equity compensation pays you in ownership of the company rather than in cash. It comes in a handful of forms that behave very differently, and the differences matter more than the shared label does. What follows is what each instrument is and what decisions it creates. The tax treatment of each is covered in our guide to taxes and in the glossary entries linked below.

Restricted stock units

A restricted stock unit is a promise to deliver shares on a schedule. Until it vests you own nothing you can sell; when it vests the shares appear in your account and their full market value is compensation, taxed as ordinary income exactly like a cash bonus of the same size. Most employers cover the withholding by keeping back a portion of the shares.

Two consequences follow, and both catch people. The first is that the withholding is frequently not enough. Employers commonly withhold on vesting shares at a flat supplemental rate that is applied without reference to your Form W-4, and for a high earner that rate sits well below the marginal rate the income is actually taxed at. The gap surfaces as a balance due at filing, sometimes with an underpayment penalty attached, and the fix is to estimate the real liability and cover it through extra withholding or estimated payments during the year.

The second is that holding vested shares is a decision, not an absence of one. Once vested, the shares are ordinary stock with a cost basis equal to the value you were taxed on. Keeping them is economically identical to taking a cash bonus and spending all of it on your employer's stock. The reason that is worth more scrutiny than an ordinary concentrated holding is discussed below.

Stock options

An option is the right to buy company stock at a price fixed when it was granted. If the share price rises above that strike price the option has value and exercising it buys stock at a discount to the market. If the price stays below, the option expires worth nothing. That asymmetry is the whole design: options pay off only if the company does well, and they can end up worthless without anything going wrong for anyone but the option holder.

Options come in two regimes. Non-qualified stock options are the ordinary kind and can be granted to anyone, including contractors and directors. Incentive stock options are a creature of the tax code, can only go to employees, and receive more favorable treatment if a set of statutory conditions and holding periods is met. The non-qualified side is named as a glossary entry that has not yet published; until it does, the practical points are these. The two regimes are taxed at different moments and in different ways, so knowing which you hold is the first question. The favorable treatment of incentive stock options requires holding the shares for at least two years from grant and one year from exercise, and selling earlier forfeits it. And the tax code limits how much of an incentive stock option grant can qualify: it tests the grant-date value of options becoming exercisable for the first time in a calendar year against a $100,000 ceiling, and anything over that is simply treated as a non-qualified option. The ceiling is on what becomes exercisable in a year, not on what you may exercise.

Employee stock purchase plans

An employee stock purchase plan takes after-tax money from your paycheck across an offering period and uses it to buy company stock at a discount, in a qualified plan up to fifteen percent. Many plans add a lookback, applying the discount to the lower of the price at the start of the offering period and the price on the purchase date, which means a rising share price makes the effective discount considerably larger than the headline figure. A well-designed plan with a lookback is one of the few structurally advantaged returns available to an ordinary employee, and a surprisingly large number of eligible people never enroll.

Two rules are widely misstated. The tax code limits participation in a qualified plan to $25,000 per calendar year, but that is a limit on the rate at which purchase rights accrue, measured at the price on the grant date, rather than a limit on what you may spend or on the value of what you receive, and unused capacity does not carry forward. And the holding period that unlocks the better tax outcome runs two years from grant, meaning the start of the offering period, and one year from purchase. Counting the two years from the purchase date is a common and expensive error.

One asymmetry is worth knowing before you decide to hold. Selling early forfeits the better treatment and makes the discount ordinary income, and for an employee stock purchase plan that ordinary income is not capped at your actual gain. If the share price falls far enough after purchase, an early sale can produce taxable compensation larger than the whole economic gain, alongside a capital loss that offsets it only slowly. Incentive stock options have a statutory cap that prevents the same outcome; these plans do not.

The concentration problem

Every form of equity compensation ends the same way: with you owning stock in the company that employs you. Left alone, grants accumulate, and a portfolio quietly becomes dominated by a single company that also pays your salary, funds your retirement plan, and provides your health insurance. The risk is not merely that a single stock is more volatile than a diversified portfolio, though it is. It is that the risks are correlated: the year the company struggles is the year the shares fall, the bonus shrinks, the remaining grants lose value, and the job is least secure, all at once.

Financial economists have long observed that an undiversified holding must earn a substantially higher expected return than a diversified portfolio just to leave the holder equally well off, because the extra risk of a single company is uncompensated by the market. The practical form of that argument is simple enough to act on: decide what share of your net worth you are willing to hold in your employer, write it down, and let the vesting schedule do the selling. Our investing guide covers diversification and why concentrated positions are hard to hold rationally.

Real constraints do cut against selling and deserve to be weighed rather than dismissed: trading windows and insider-trading policies restrict when you can act, senior employees may face minimum shareholding requirements, private company shares may have no market at all, and selling incentive stock option shares early can forfeit favorable treatment. The argument here is not that selling is always right. It is that holding should be a position you took on purpose.

One last item, because it is asked constantly and the answer is unambiguous. A Section 83(b) election lets someone who receives restricted stock that is still forfeitable elect to be taxed on its value at grant rather than as it vests, which can be valuable when the value is low and expected to rise. It must be filed within thirty days of the transfer, and the deadline is absolute. It does not apply to restricted stock units at all: the statute says so expressly, because an RSU is a promise rather than property. Guidance suggesting you can make an 83(b) election on RSUs is simply wrong. And where the election is available it carries a real risk, because tax paid at grant is not refunded if the stock later falls or you leave before vesting.

What else is in the package?

Underneath the headline benefits sits a set of smaller programs that are collectively worth more than most employees realize, largely because each is authorised by its own rule with its own ceiling and none of them appears on a pay stub. The useful instruction is to read your own benefits guide once a year, because what is offered varies enormously between employers and none of it is automatic.

• Educational assistance. An employer may pay for job-related and general education up to an annual ceiling without it becoming taxable income to you, and our education funding guide covers how it coordinates with the education tax credits. The same program may also be used to repay your student loans, whether payments go to you or directly to the lender. That student loan feature had an expiry date attached for years and was made permanent by the 2025 tax law, so a great deal of published guidance describing it as expiring at the end of 2025 is now out of date.
• A retirement match on student loan payments. A separate and newer route lets an employer treat your qualifying student loan payments as if they were retirement contributions and match them into the plan, so that paying down loans no longer means giving up the match. It is optional for employers, so the question is whether yours has adopted it. Note the limit: only payments up to the year's deferral ceiling, reduced by what you actually deferred into the plan, can be matched this way, so it fills the gap rather than stacking on top of a full contribution.
• Dependent care assistance. Money set aside before tax for childcare, day camp, or care for a disabled dependant so that you can work. It competes with a tax credit for the same expenses and the same dollar cannot be used twice, so the two are worth comparing rather than assuming the pre-tax account wins.
• Commuter benefits. Pre-tax money for transit passes and qualified parking, capped monthly. One historical note prevents an error: the bicycle commuting benefit was suspended in 2017 and has now been permanently eliminated rather than restored, so sources describing it as returning are wrong.
• Adoption assistance. Employer reimbursement of qualified adoption expenses, excludable up to a ceiling and separate from the adoption tax credit.
• Employee assistance programs. Confidential counseling, legal and financial referral services, usually free and usually forgotten. Coverage often extends to household members.
• Small non-cash items. Occasional benefits of minimal value can be excluded from income, but the category is narrower than people assume, and there is no dollar threshold in the rules that makes something automatically minimal. Cash is the hard case: the rules treat it as outside the exclusion apart from a narrow allowance for things like occasional overtime meal money and cab fare, and treat a gift card as outside it too, however small the amount.

Because most of these are capped in dollars that change from year to year, the amounts are not printed here. Your benefits portal and the current-year figures on the relevant glossary pages carry them.

What changes at higher pay?

Two things change once compensation rises past certain thresholds. The ordinary plans start to constrain you, and a different category of plan appears to compensate for it.

The constraint comes from the rules that stop a workplace retirement plan from favoring the people who run the company. Being classified as a highly compensated employee does not cap anything by itself; it identifies whose contributions get compared against everyone else's. Where the comparison fails, the plan corrects it, sometimes by refunding part of a high earner's contributions after the year has ended. That is a surprise worth anticipating rather than discovering, and plans designed around a safe harbor avoid the test entirely.

The compensating plan is nonqualified deferred compensation: an agreement to be paid in a later year, outside the qualified plan rules. It has no contribution limit, which is the attraction, and it can be genuinely useful for someone who expects a materially lower tax rate later.

What happens to all of this when I leave?

Everything in your benefits package comes due at once when you leave a job, on different clocks, and most of the deadlines are short. Almost all of it is knowable in advance, which makes the weeks before a departure the point at which planning is worth the most. The resignation date itself is sometimes the lever. If the departure was not your choice, our guide to government benefits covers unemployment insurance alongside it. And if you are leaving to work for yourself, every item below stops having an employer behind it rather than simply ending, which our guide to small business and self-employment works through in that order.

• Unvested employer money is generally gone. Employer contributions to the retirement plan that have not vested are forfeited; your own contributions and their earnings are always yours. If a vesting date is near, its value is on your statement and is worth comparing against the cost of delaying a start date.
• Unvested equity is generally gone too, and vested options come with a clock. Most plans give a short window after employment ends, frequently around ninety days, to exercise vested options before they lapse. Exercising means finding the cash to buy the shares and possibly a tax bill in the same year, so this deadline can be expensive to meet and worse to miss.
• Health coverage ends on a date set by the plan, which may be your last day or the end of that month. COBRA lets you keep the same plan at your own expense, generally for eighteen months after a job ends and up to thirty-six for events such as divorce or a child aging off the plan. You have sixty days to elect and a further forty-five days to pay the first premium, and coverage is retroactive to the gap, which means COBRA can be held open as an option rather than elected immediately. The price is the shock: you pay the employer's share as well as your own, plus an administrative charge.
• The Marketplace is the usual alternative, and the door swings one way. Losing job-based coverage opens a special enrollment period to buy an individual plan, and marketplace coverage with a subsidy is often cheaper than COBRA. But once you elect COBRA, dropping it voluntarily or simply stopping payment does not open that door again; you would generally wait for open enrollment. Running COBRA to its natural exhaustion does, and so does one situation worth knowing if you are negotiating a severance: where an employer had been paying part of your COBRA premium and completely stops, that cessation opens a special enrollment period of its own. Choose in the first sixty days rather than assuming you can switch later.
• A health FSA is usually forfeited; an HSA is yours. Money left in a health flexible spending account is generally lost when employment ends, though you may be able to continue it under COBRA in some circumstances, and spending the balance before the last day is often the simplest answer. A health savings account is your property and moves with you regardless of where you work next.
• Group life and disability end with the job. Life insurance may carry a conversion right exercisable within weeks and priced far above group rates. Group disability generally just stops. If either was doing real work in your plan, replacing it needs to start before you leave, while you are still insurable.
• The retirement account has four options, and none of them expires immediately: leave it in the old plan if permitted, roll it into the new employer's plan, roll it into an individual retirement account, or cash it out. The last is the expensive one, and our retirement guide covers the mechanics of the others.
• Severance is a negotiated document, not an entitlement. There is no general federal requirement to pay it. What is offered is usually conditioned on signing a release of claims, frequently comes with a review period, and may address the treatment of equity and continued health coverage, all of which are terms rather than fixed outcomes.

Two smaller items round out the list. Whether accrued paid time off is paid out depends on state law and employer policy rather than federal law. And if you are approaching sixty-five, the interaction between employer coverage, COBRA and Medicare enrollment has a penalty attached to getting it wrong, which our insurance guide sets out.

Common mistakes

• Contributing below the match. The most expensive routine mistake in personal finance, and it is a voluntary pay cut. Automatic enrollment defaults frequently sit below the level that captures the whole match, so being enrolled is not the same as being enrolled at the right rate.
• Counting unvested employer money as yours. A retirement statement shows a total balance; the vested portion is what you would keep if you left tomorrow, and the two figures can be far apart in the early years.
• Letting a general-purpose health FSA quietly end HSA eligibility. This includes a spouse's FSA, and a carryover or grace period can push the block into the next plan year.
• Treating the tax withheld on vesting shares as the tax owed. The flat supplemental rate applied to equity compensation is often well below a high earner's marginal rate, and the shortfall appears at filing.
• Accepting the 1099-B basis on sold equity-comp shares. The reported basis excludes income already taxed on your W-2, by regulation rather than by error, and entering it as shown taxes the same money twice.
• Assuming FMLA pays. It protects the job and continues health coverage. It provides no income, and the employer may recover the premiums it paid if you do not return.
• Holding employer stock by default. Concentration that arrives through a vesting schedule is still concentration, and it is correlated with the job that produced it.
• Missing the window to exercise vested options after leaving. It is often around ninety days, it starts on the last day of employment, and expired options are simply gone.
• Electing COBRA without pricing the Marketplace first. Subsidised individual coverage is frequently cheaper, and once COBRA is elected, voluntarily dropping it does not open a special enrollment period.
• Never reading the summary plan description. Match true-ups, vesting schedules, whether a limited-purpose FSA is offered, and post-termination exercise windows are all in the documents and nowhere else.

When is professional help worth it?

Most benefits decisions are ones you can make yourself with an afternoon and the plan documents. Setting a contribution rate that captures the match, comparing two health plans on total annual cost, and choosing whether to pay a disability premium after tax are all finishable at a kitchen table.

A smaller set is different in kind, because the decision happens once, the amounts are large, and the choice cannot be revisited. Whether and when to exercise incentive stock options, given that the alternative minimum tax consequences changed for 2026 and that selling in the wrong tax year undoes the planning. What to do with a vest large enough to move your bracket. Whether to defer compensation into a plan whose money remains the employer's asset, and for how long. How to unwind a concentrated position built over years of grants without triggering an avoidable tax bill. And the benefits side of a job change, where a vesting date, an option window, a COBRA election and a retirement rollover all land in the same few weeks.

These share a shape: the analysis is worth more before the decision than after it, and the cost of getting one wrong is measured in years of contributions. If you want a second set of eyes on one of them, our advisor directory lets you filter for planners who work on employee benefits, and separately for those who specialize in equity compensation.
