Is Severance Pay Taxed Differently? Withholding vs Actual Tax

Severance looks like a bonus on your pay stub because the IRS treats it the same way. The 22% withholding is not your tax rate; it is a down payment.

Supplemental wages: the 22% rule

The IRS classifies severance as supplemental wages, the same bucket as bonuses and commissions. Employers withhold federal income tax at a flat 22 percent on the first $1 million of supplemental wages in a year, and 37 percent above $1 million (IRS Publication 15). This is mandatory withholding, not an election; your employer cannot withhold at your W-4 rate instead.

Crucially, withholding is not tax. Your actual tax on the severance is computed at your marginal ordinary-income rate when you file. A worker in the 12 percent bracket who had 22 percent withheld gets the 10-point difference back as a refund. A worker in the 32 percent bracket owes another 10 points in April. The withholding is a rough estimate that is wrong for almost everyone by design.

FICA and state taxes

Social Security (6.2 percent up to the annual wage base) and Medicare (1.45 percent, plus the 0.9 percent additional Medicare tax above $200,000) apply to severance just like wages. If you already hit the Social Security wage base with your regular salary before the layoff, no additional Social Security tax is due on the severance, a small silver lining. State withholding follows your state's supplemental-wage rate, which ranges from zero in no-income-tax states to over 10 percent in high-tax states.

Lump sum versus salary continuation

How the severance is paid changes the tax timing. A lump sum lands entirely in the year of payment, which can bunch income and push you into a higher bracket. Salary continuation (staying on payroll for the severance period) spreads the income across pay periods and sometimes across tax years, which can keep you in a lower bracket and preserves benefits like 401(k) contributions during the continuation period. If you have a choice, model both: a December layoff with January salary continuation can split the income across two tax years.

Unemployment benefits are taxable too

Unemployment compensation is taxable income federally (most states tax it as well, with a few exceptions). You can elect 10 percent federal withholding on benefits via Form W-4V, which many people skip and regret in April. Factor the tax on benefits into your cash planning alongside the severance withholding.

Planning moves before year end

A large severance year is a good year for deduction bunching: charitable gifts, deductible expenses, and HSA or retirement contributions offset the bunched income. If the severance pushes you into a higher bracket, accelerating deductions into the severance year saves tax at that higher marginal rate. Conversely, Roth conversions are usually a bad idea in a severance year; wait for the lower-income year that often follows.

The withholding gap in numbers

Take a worker whose marginal rate is 32 percent receiving $25,577 of severance. Federal withholding at 22 percent takes $5,627, but the actual federal tax at 32 percent is $8,185, leaving $2,558 due in April before considering any other income changes. The same severance for a worker in the 12 percent bracket generates $3,069 of actual tax against $5,627 withheld, a $2,558 refund. Same package, opposite April outcomes, which is why the 22 percent figure should never be mistaken for your tax rate. Adjust remaining withholding or make an estimated payment to cover the gap if you are in the higher bracket.

Frequently asked questions

Is severance taxed at 22%?

Federal withholding is a flat 22% (37% above $1M in supplemental wages), but your actual tax is at your marginal ordinary-income rate. The 22% is withholding, not your tax rate.

Do you pay Social Security tax on severance?

Yes, unless you already exceeded the annual Social Security wage base with your regular salary. Medicare tax always applies.

Is lump-sum or salary continuation better for taxes?

Salary continuation can spread income across tax years and preserve benefits; lump sums bunch income into one year. Model both before choosing if you have the option.

Are unemployment benefits taxable?

Yes, federally and in most states. You can elect 10% federal withholding with Form W-4V.

Should I do a Roth conversion in my severance year?

Usually not. The bunched severance income puts you in a higher bracket; conversions are generally better in the lower-income year that follows.
