Severance Pay Taxes and Take-Home: 2026 Calculator Guide

Quick Answer: How Much of a Severance Do You Actually Keep?

A lump-sum severance is taxed as supplemental wages. Federal income tax is withheld at a flat 22% (up to $1 million per year), Social Security takes 6.2% until your year-to-date wages hit the 2026 wage base of $184,500, Medicare takes 1.45% on every dollar, and your state may add more.

Rule of thumb for 2026: In a no-income-tax state like Texas, you'll keep about 70% of a moderate severance after withholding. In California, the figure drops to roughly 60% after state income tax and SDI.

Withholding is just a prepayment, not your final tax bill. The IRS settles up on your 1040 based on your total annual income, so smaller severances often produce a refund and larger ones may leave a balance due.

How Severance Pay Is Taxed in 2026: The Four Taxes That Apply

Severance is fully taxable wages. The IRS spells this out in Publication 15: "Severance payments are wages subject to social security and Medicare taxes, federal income tax withholding, and FUTA tax." Four separate taxes come out before the money hits your account.

1. Federal income tax

Severance is a supplemental wage. Employers can withhold it two ways: a flat 22% on a separate severance check, or the aggregate method that combines the severance with regular wages and uses your W-4 tables. Either way, your true federal liability gets reconciled on your 1040.

2. Social Security (6.2%)

Social Security tax applies to severance up to the 2026 wage base of $184,500. Once your year-to-date Social Security wages with that employer pass the cap, the 6.2% stops. For a worker laid off mid-year who already crossed the base, the entire severance escapes Social Security tax.

3. Medicare (1.45%, plus 0.9% above $200K)

Medicare has no wage cap. Every dollar of severance is hit with 1.45%. Once cumulative wages with the employer cross $200,000 in a calendar year, an extra 0.9% Additional Medicare Tax kicks in on the dollars above the threshold. Your final liability gets reconciled on Form 8959 based on total household wages and filing status.

4. State income tax (and special funds)

Forty-one states tax wages, and most of them use a flat supplemental rate or just withhold at their normal income-tax tables. California adds SDI, New York adds PFL and DBL, and several other states pile on small disability or paid-family-leave premiums. Nine states (AK, FL, NV, NH, SD, TN, TX, WA, WY) take nothing.

The 22% Flat Rate Trap: Withholding vs. Actual Tax Liability

The most common confusion about severance is treating the 22% federal withholding as the final tax. It is not. It is an estimate the employer uses because they don't know your filing status, deductions, or other income.

How the flat rate works

If your supplemental wages from a single employer stay under $1,000,000 in a calendar year, your employer can use the percentage method: a flat 22% federal withholding on the severance, ignoring your W-4. Above $1 million, the excess is withheld at 37%, the top federal marginal rate. That higher rate is mandatory, not optional.

Why 22% is rarely your real tax

Your actual federal income tax depends on your marginal bracket after all of 2026's income is added up. The 2026 single-filer brackets after the One Big Beautiful Bill (P.L. 119-21) are:

• 10% up to $12,400
• 12% to $50,400
• 22% to $105,700
• 24% to $201,775
• 32% to $256,225
• 35% to $640,600
• 37% above $640,600

If your total 2026 income lands in the 12% bracket, the 22% withholding over-collects and you'll see a refund. If you land in the 24% or higher brackets (common when severance stacks on a half-year of salary), 22% under-withholds and you may owe at filing.

When employers fold severance into a regular check

If the severance is paid alongside a regular paycheck instead of separately, payroll often uses the aggregate method. They add the severance to the period's wages, look up the combined amount on the IRS withholding tables, and treat it as your annual pace. That can over-withhold dramatically because a single big check looks like a very high salary when annualized.

Lump Sum vs. Salary Continuation: Which Costs You More?

Many severance offers give you a choice: take the full payout now as a lump sum, or receive your salary on the regular payroll cycle for several weeks or months ("salary continuation"). The conventional wisdom that one is "better for taxes" misses how the math actually works.

Withholding mechanics differ

A lump sum on a separate check usually triggers the flat 22% federal withholding. Salary continuation runs through normal payroll and uses your W-4 tables, often producing a smoother, lower per-paycheck withholding. The total withheld over the year may differ between the two.

Final tax bill is the same (in the same year)

If both arrangements pay out entirely in 2026, your final tax liability is identical. The IRS doesn't care whether $50,000 arrived in one check or eight. It applies your marginal bracket to your total annual income and reconciles on the 1040. Whatever the employer over- or under-withheld balances out as a refund or a payment due.

The real lever: shifting income across calendar years

The only way to genuinely reduce the tax is to push severance into a year with lower total income. A December layoff with a January payout shifts the income into the next tax year, when your wages may drop and a bigger chunk of severance falls into lower brackets. If your offer is timed near year-end, it is worth asking whether a small delay is feasible.

Non-tax reasons to prefer continuation

Some employers extend health insurance, 401(k) eligibility, or vesting timelines while you are on salary continuation. Those benefits can be worth more than the tax difference, especially if you are between jobs and a few extra weeks of group health coverage saves a COBRA premium.

Severance Take-Home by State: $10K, $50K, $100K Examples

The biggest swing in severance take-home is your state. Three examples below use 2026 rates, single filer, with no other income for the year. All figures come from a paycheck calculator.

Small severance ($10,000)

On a $10,000 severance with no other 2026 income, the standard deduction ($16,100 single) wipes out federal income tax entirely. FICA still applies, and state varies:

• Texas: Net $9,235 after $620 Social Security and $145 Medicare.
• California: Net $9,058 after FICA, $47 state tax, and $130 SDI.
• New York: Net $9,083 after FICA, $78 state tax, and $74 PFL/DBL.

The 22% your employer initially withheld will mostly come back at filing because federal income tax was actually $0.

Mid severance ($50,000)

A $50,000 lump-sum severance, no other income, single filer in Texas: net $42,355 for an effective rate near 15.3%. California and New York add roughly $1,500 to $3,500 more in state-level tax.

Large severance ($100,000, Texas)

A $100,000 lump-sum severance, no other income, single filer:

• Federal income tax: $13,170
• Social Security: $6,200
• Medicare: $1,450
• Net take-home: $79,180 (effective rate roughly 20.8%)

$250,000 total comp ($200K base + $50K severance)

For a worker laid off mid-year who has already earned a $200,000 salary, the state gap balloons:

• Texas: Net $179,571
• California: Net $155,247 (state $21,074 + SDI $3,250)
• New York: Net $163,929 (state $14,531 + PFL/DBL $1,111)

A Californian keeps roughly $24,000 less than a Texan on identical gross pay. That is the price of state tax plus SDI on a top-of-base income.

The FICA Wage Base Gotcha Most Articles Miss

If you have already crossed the 2026 Social Security wage base of $184,500 with your year-to-date wages, your severance escapes the 6.2% Social Security tax entirely. At the cap, that's a savings of up to $11,439. Most severance articles never mention it.

How the cap works

Your employer tracks your year-to-date wages. Once they pass $184,500 for the year, no more Social Security tax comes out. If you are laid off in October after a $190,000 year, your severance pays zero Social Security tax. If you are laid off in March with $40,000 of YTD wages, every severance dollar pays the full 6.2% until you reach the cap.

But Additional Medicare still applies

The same high earners avoiding Social Security usually trip the Additional Medicare Tax. Once cumulative wages with the employer cross $200,000 in 2026, an extra 0.9% comes out on the excess. So a high-earner severance saves on Social Security but pays a small premium on Medicare.

Worked example

Single filer in New York with $200,000 base wages already paid for 2026, then a $100,000 severance:

• Federal income tax: $68,134
• New York state tax: $17,956
• Social Security: $0 (wage base already hit)
• Medicare: $6,910 (includes 0.9% additional on wages above $200K)
• Net: $206,999

If the same worker had been below the wage base for most of the year, the bill would include another $11,439 in Social Security tax, dropping the net by that amount. For high earners, when you are laid off matters as much as how much you receive.

New job mid-year resets the cap

One nuance: the wage base tracks per employer, not per person. If you start a new job after your layoff, that new employer restarts your Social Security wage base from $0. You may overpay across the year and recover the difference as a credit on your 1040.

Five Ways to Lower Your Severance Tax Bill (Legally)

Once severance is paid, your tax options narrow. The biggest savings come from planning before the check arrives. Five practical moves:

1. Negotiate the payment year

If your offer is being finalized in November or December, ask whether the payout can land in January. Pushing the income into a year when your salary is partial or zero can drop large chunks of severance into lower brackets. Combined with the standard deduction, the savings can run into the thousands.

2. Max your 401(k) on your final regular paycheck

True severance pay is not eligible for elective 401(k) deferrals because it is paid after the employment relationship ends. But your final regular paycheck still is. Bumping your contribution rate to defer as much as possible on that last check moves taxable wages into your retirement account. Confirm with payroll how the cutoff is treated.

3. Fund an HSA if you are still on an HDHP

If your last day of HDHP coverage falls late in the year, you may be eligible to contribute to an HSA for the months you were covered. The HSA contribution reduces taxable income and never gets taxed if used for qualified medical expenses.

4. Bunch charitable deductions through a DAF

If your severance pushes you into itemizing for the year, a donor-advised fund lets you front-load several years of charitable giving into the high-income year. You take the full deduction now and grant out to charities over time.

5. Spread payouts via salary continuation if next year looks lean

If your employer offers salary continuation and you expect lower income across the next calendar year, the continuation payments that cross into the new year fall into lower brackets. This is the same lever as negotiating the timing, just expressed through the payout schedule rather than a single delay.

Frequently Asked Questions

Severance Planning Tips

• Budget off the net, not the gross. A $50,000 severance is not $50,000 of spending money. Plan around 60 to 75 percent depending on your state and how much other 2026 income you'll have.
• Ask about timing before signing. If the offer can be paid in January instead of December, the income falls into a year with potentially lower total wages and can drop into lower brackets.
• Confirm the withholding method. Ask payroll whether severance comes on a separate check (flat 22%) or combined with a regular paycheck (aggregate). The aggregate method often over-withholds dramatically on a single big check.
• Watch the Social Security wage base. If your YTD wages are near $184,500 in 2026, you may escape the 6.2% on most or all of the severance. That can be more than $11,000 in savings.
• Max your 401(k) on the final regular paycheck. Severance itself usually cannot defer, but your last regular check can. Bump the contribution rate ahead of payroll cutoff.
• Model the full year. Run salary plus severance plus any side income through the paycheck calculator before tuning your W-4 or estimating quarterly tax payments.
