A $60,000 Severance, 22% Withheld, and a 32% Bill in April

A laid-off worker receiving a $60,000 severance payment has 22% withheld under the IRS flat supplemental-wage rule, but may face a 32% marginal rate at filing in April, leaving a shortfall of roughly $6,000 on that payment alone if no extra tax is paid in.

A worker who is let go and handed a $60,000 severance check sees roughly a fifth of it disappear before the money arrives. Payroll withheld 22%, which is exactly what the IRS instructs employers to do on a supplemental wage payment of that size. Nothing was miscoded, no W-4 was mishandled, and no one at the company made an error. And yet the same worker can open a tax return the following April and find thousands of dollars still owed on money that already looked taxed.

The gap is structural. Withholding on severance is a flat rate applied to a single payment in isolation. The tax actually owed is a marginal rate applied to a full year of stacked income. Those two calculations are not designed to match, and when a severance payment pushes a household into a 32% marginal bracket, they do not come close.

Why payroll uses 22% on a severance check

The IRS treats severance as a supplemental wage — the same category as bonuses, commissions, back pay and payouts for accrued vacation. Supplemental wages are not regular salary, so employers are not required to run them through the ordinary wage-withholding tables tied to a W-4. Instead, the common method is a flat percentage: 22% is withheld and remitted, and the payment is reported on the year's W-2 alongside everything else.

The flat rate exists for administrative simplicity. A payroll department processing a reduction in force has no view of a departing employee's spouse's income, investment gains, a prior employer's wages, or a bonus already paid in January. It withholds at the rate the rules specify and moves on. That is compliance, not carelessness — and it is precisely why the number on the stub carries no promise about the final bill.

How stacking turns 22% into 32%

Federal income tax is marginal. Income is layered, and each additional dollar is taxed at the rate that applies to the layer it lands in. Severance does not get its own private tax calculation at year end; it sits on top of every other dollar of taxable income the household reports for the year — wages earned before the layoff, a spouse's salary, interest, dividends, capital gains, retirement distributions.

If all of that other income has already filled the lower brackets, the severance falls into a higher one. When the applicable marginal rate is 32%, the difference between what was withheld and what is owed on that payment is 10 percentage points. On $60,000, that works out to about $6,000 of tax that was never collected during the year — an illustrative figure based on the full payment being taxed at the higher marginal rate. Withholding at 22% would have covered roughly $13,200; a 32% rate on the same payment implies about $19,200.

Two features of a layoff year make the mismatch worse rather than better:

Front-loaded income. A mid-year separation often means a full stretch of salary plus a lump sum, concentrating income into the first part of the calendar year.
Accrued payouts. Unused vacation, deferred bonus and other cash-outs are usually settled at the same time, all as supplemental wages at the same flat rate.
No offsetting drop. The tax savings from a lower-income stretch of unemployment land in the same year only if the unemployment actually runs long — and unemployment benefits are themselves taxable.

The same arithmetic works in reverse for some people. A worker whose total income for the year falls low enough that the severance sits in a bracket below 22% will have over-withheld, and the excess comes back as a refund. The flat rate is a blunt instrument in both directions, as 24/7 Wall St laid out in its walk-through of the $60,000 example.

Closing the gap before the return is due

The federal system is pay-as-you-go. Tax is expected to be paid in over the course of the year, not settled in a single April transfer. A worker who knows a shortfall is coming has a handful of levers, and most of them expire at year end.

Make an estimated tax payment. Quarterly estimated payments exist for exactly this situation: income that arrives without adequate withholding. Paying the estimated gap in the quarter the severance is received keeps the liability current and limits underpayment penalties, which are charged by period rather than as a single year-end assessment.

Increase withholding on any remaining wage income. If the laid-off worker starts a new job, or a spouse is still on payroll, a revised W-4 with additional withholding can cover the gap. Withholding carries a timing advantage over estimated payments: it is generally treated as paid evenly across the year regardless of when it is actually taken, which can repair an earlier shortfall.

Withhold on unemployment benefits. Unemployment compensation is taxable income, and no tax is taken out unless it is requested. Leaving it untouched adds to the same April problem.

Look at deductible moves in the same tax year. Contributions to a traditional retirement account or a health savings account, where eligibility exists, reduce taxable income in the year the severance lands. Whether that helps depends on the household's circumstances, and it only helps for the year in which it is done.

The cash-flow trap behind the tax trap

The tax bill is the visible problem. The harder one is that severance is usually the bridge between jobs. Money that is mentally earmarked for rent, health coverage and a job search is also, silently, carrying an unfunded tax liability.

Setting aside the difference between the withheld rate and the expected marginal rate — segregated, not merged into a checking account — converts an April surprise into a known cost. That is more discipline than most people apply to a lump sum arriving at the worst possible moment, which is exactly why the shortfall is so common.

It also argues for caution about deploying the full net amount. Markets closed higher on Friday, Sept. 11, 2026, with the S&P 500 tracker SPY at $764.29, up 0.85% on the day, and the Nasdaq 100 fund QQQ at $714.88, up 0.87%. A rising tape is a poor reason to invest money that is already promised to the Treasury: a severance cushion with an embedded tax bill is not surplus capital, and a drawdown between now and filing season would force the worst version of the trade.

What to check before December 31

The practical test is a full-year projection rather than a glance at a pay stub. Total the wages earned before separation, the severance and any accrued payouts, a spouse's income, investment income and unemployment benefits. Compare the resulting marginal rate against the 22% already withheld on the supplemental wages. If the marginal rate is higher, the difference is a debt with a due date, and the last quarterly estimated payment of the tax year is the final clean chance to settle it on schedule.

Frequently asked questions

Why is severance withheld at 22% instead of my normal payroll rate?

The IRS classifies severance as a supplemental wage, the same category as bonuses and commissions. Employers are permitted to withhold a flat percentage on those payments rather than running them through the regular wage tables tied to your W-4. For supplemental wages at this level the flat rate is 22%, applied to the payment in isolation from your other income.

How much could be owed on a $60,000 severance taxed at 32%?

Withholding at 22% would cover about $13,200 of the payment, while a 32% marginal rate implies roughly $19,200 of tax. That leaves an illustrative shortfall near $6,000 on that payment alone, assuming the entire severance sits in the higher bracket. The actual figure depends on total household income, deductions and filing status.

Did my employer make a mistake by withholding only 22%?

No. The flat supplemental-wage rate is what the IRS instructs employers to apply, and payroll has no visibility into a spouse's earnings, investment gains or income from a prior employer. The withholding is correct as a compliance matter. It simply is not designed to predict your final marginal rate for the year.

What is bracket stacking?

Federal income tax is marginal, meaning income is layered and each additional dollar is taxed at the rate applying to the layer it falls in. Severance does not receive a separate calculation; it stacks on top of wages, a spouse's income, interest, dividends and capital gains. If the lower brackets are already filled, the severance lands in a higher one.

Can I fix the shortfall before April?

Yes. You can make an estimated tax payment for the quarter in which the severance arrived, or increase withholding on any remaining wage income through a revised W-4. Withholding has a timing advantage because it is generally treated as paid evenly across the year, which can repair a shortfall created earlier in the year.

Are unemployment benefits taxed too?

Unemployment compensation is taxable income at the federal level, and no tax is withheld from it unless you specifically request withholding. Leaving benefits untaxed during the year adds to the same April liability created by a severance payment withheld at the flat supplemental rate, compounding an already underfunded tax position.
