How Is Severance Taxed? Withholding vs. What You Actually Owe

Yes, severance is taxable, and the check that lands in your account is often smaller than the number in your separation agreement. Most of the gap comes from tax withholding, and the amount withheld is an estimate, not your final bill. This guide explains how severance is taxed at each level: what your employer withholds, what you actually owe when you file, and the payroll tax quirks that can change the math.

Is severance pay taxable?

Yes. The IRS says so in plain terms. Publication 525 states, “You must include in income amounts you receive as severance pay.” It is ordinary income in the year it is paid, taxed the same way as your salary.

Payroll taxes apply too. Publication 15 says, “Severance payments are wages subject to social security and Medicare taxes, federal income tax withholding, and FUTA tax.” An amount paid for cancellation of an employment contract is treated the same way. The Supreme Court settled the FICA question in United States v. Quality Stores, Inc. (March 25, 2014): “Under FICA’s broad definition, these severance payments constitute taxable wages.”

Here is how the severance package taxes break down:

Tax	Applies to severance?	What to know
Federal income tax	Yes	Withheld at a flat 22% or by the aggregate method; 37% on supplemental wages above $1 million in a year. Final tax is settled on your return.
Social Security	Yes	6.2% up to the yearly wage base ($184,500 for 2026, $192,300 for 2027). Nothing above the base.
Medicare	Yes	1.45% on all wages, no cap.
Additional Medicare Tax	Yes, above the threshold	0.9%, withheld on wages above $200,000 in a calendar year. The employer does not match it.
FUTA	Yes	Paid by the employer only. It never comes out of your check.
State income tax	Generally	Applies where your state taxes wages. Rules and rates vary by state.

How federal withholding works on severance

Severance is a type of supplemental wages, meaning pay that is not part of your regular salary. Bonuses, commissions, overtime, payments for accumulated sick leave, awards and back pay are in the same group, as summarized by the Colorado Office of the State Controller from Treasury Regulation 31.3402(g)-1. That label matters because it lets your employer use special withholding methods.

If the employer withheld income tax from your regular wages and the severance is paid as a separate, identified payment, it may use either of two methods:

• The flat rate. Withhold 22% of the payment. Publication 15 notes that the withholding rate on supplemental wages remains 22%.
• The aggregate method. Add the severance to your regular wages for that pay period, figure withholding on the total as if it were one paycheck, then subtract what was already withheld.

Above $1 million of supplemental wages paid to you in a calendar year, withholding on the excess is a mandatory 37%. The mechanics are the same as for bonuses, so our post on why a bonus paycheck looks overtaxed covers the supplemental-wage rules in more depth.

Here is a simple example. Say you receive a $30,000 lump sum and the employer uses the flat rate:

• Federal income tax withheld: $30,000 x 22% = $6,600
• Social Security: $30,000 x 6.2% = $1,860
• Medicare: $30,000 x 1.45% = $435

That is $8,895 withheld before any state tax or other deductions. Your severance pay tax rate on the check, in other words, is not one number: it is a federal withholding rate plus payroll taxes plus any state withholding.

Lump sum versus salary continuation. If your severance is paid in installments on the regular payroll schedule (often called salary continuation), it is typically withheld like regular pay, using the Form W-4 you have on file. The flat 22% usually shows up with a one-time lump sum.

Withholding is not your final tax

The 22% is a withholding rate, not the tax you owe. Your actual tax is figured on your return from your total income for the year and your marginal bracket. That means a lump sum can be over-withheld or under-withheld:

• Over-withheld: if your income for the year puts the severance in a bracket below 22%, you get the excess back as a refund.
• Under-withheld: if your income puts it in a bracket above 22%, you owe the difference when you file.

For illustration only, suppose the whole $30,000 were taxed at a hypothetical 12%. The tax would be $3,600, and the $6,600 withheld would be $3,000 too much. At a hypothetical 32%, the tax would be $9,600, and $6,600 would fall $3,000 short. Real returns blend several brackets; our explainer on marginal vs. effective tax rate shows how that works.

Two things push toward under-withholding. First, severance stacks on top of the wages you already earned that year, so it often lands in your highest bracket. Second, if you start a new job after the layoff, your combined income for the year may be higher than you expect.

Social Security wage base and Additional Medicare Tax

Social Security tax stops once your wages for the year pass the wage base: $184,500 for 2026 and $192,300 for 2027, according to the Social Security Administration. Medicare has no cap.

Suppose you earned $170,000 in 2026 wages before a $30,000 severance check. Only $14,500 sits below the $184,500 base ($184,500 – $170,000), so Social Security tax on the severance is $14,500 x 6.2% = $899, not $1,860. The remaining $15,500 is not subject to the 6.2% tax.

Timing matters. The base resets every January 1. A payment made in December counts toward the old year’s base, while the same payment made in January starts counting toward the new year’s. A $30,000 payment that is the first wages of a new year is fully subject to the 6.2%, or $1,860. Our post on the paycheck increase after the Social Security wage base shows how the cutoff changes a paycheck.

Additional Medicare Tax is 0.9%. Your employer must withhold it on wages it pays you above $200,000 in a calendar year, without regard to your filing status. If you earned $190,000 and receive $30,000 of severance, wages reach $220,000, so $20,000 is above the line and $20,000 x 0.9% = $180 is withheld. Your actual liability threshold depends on filing status: $250,000 married filing jointly, $125,000 married filing separately, and $200,000 for everyone else. Employers do not match this tax, and any difference is settled on your return.

Unused PTO and sick leave paid out with severance

A payout of accumulated sick leave is named as supplemental wages, and a payout of unused paid time off is generally handled the same way. These amounts are taxable wages, subject to the same income tax withholding, Social Security and Medicare. If your final check bundles severance with a leave payout, the total may all be treated as one supplemental payment, so the two can be hard to separate on the stub.

Severance pay and unemployment

Unemployment benefits are generally taxable income too. They are reported on Form 1099-G, and you can choose to have federal tax withheld by filing Form W-4V, as explained in IRS Topic 418.

Whether severance reduces your benefits, delays them or has no effect on them is decided by each state, not by the IRS. Check your state unemployment agency’s rules, and report your severance when you apply. Leaving it off an application can create problems later.

What to do when you get a severance check

• Read the final pay stub. Confirm how the severance was classified and which withholding method was used. Our guide to reading your pay stub helps decode each line.
• Estimate your real tax. Compare the withholding with your expected total income for the year. Our PaycheckNet tax calculator can help you run the numbers.
• Cover any shortfall. If you expect to owe more than what was withheld, consider an estimated payment (see who needs to pay quarterly) or a Form W-4 adjustment at a new job (see how to fill out a W-4).
• Do not assume your usual 401(k) percentage applies. Plans differ on whether severance is eligible for deferrals, so check with your plan administrator.
• Keep your separation agreement. Save it with your final pay stub and your Form W-2 so you can match each payment to what was reported.
