Severance is taxed at a higher rate because the IRS treats it as a lump sum paid all at once, not spread across the year

Your severance pay is subject to federal withholding tax, state income tax, Social Security tax, and Medicare tax — the same taxes as your regular wages. The difference is how much gets withheld. When your employer pays severance in one large check instead of regular paychecks, the payroll system calculates withholding as if you earn that amount every pay period for the entire year. This pushes you into a higher tax bracket temporarily, even though your actual annual income may not have changed much.

For example, if you receive $30,000 in severance on a single paycheck and your employer uses the IRS's standard withholding tables, the system treats it as if you earn $30,000 every two weeks. That calculation lands you in a much higher bracket than you'd actually occupy for the year. Your employer withholds accordingly — often 22% to 37% of the severance — even though your true tax liability for the year might be lower.

The good news: this is withholding, not your actual tax bill. When you file your tax return the following year, the IRS recalculates what you actually owe based on your real total income. If too much was withheld, you get a refund. If too little, you owe the difference.

Key Takeaways

  • Severance is taxed using the same rates as regular income, but withholding is calculated as if the lump sum is your regular pay period amount, pushing you into a higher bracket temporarily.
  • Your employer must withhold federal income tax, state income tax, Social Security tax (6.2%), and Medicare tax (1.45%) from severance pay.
  • The amount withheld is not your final tax bill — it is an estimate that gets corrected when you file your return and report your actual year's income.
  • You can reduce withholding by claiming severance as a special one-time payment on Form W-4, though not all employers honor this request.
  • If you receive severance and lose your job, you may owe taxes on income you no longer have, so setting aside money or planning ahead prevents a surprise bill.

How the IRS withholding tables create the higher rate

The IRS publishes withholding tables that employers use to calculate how much tax to take from each paycheck. These tables assume the amount on that check is what you earn in every pay period. If you normally earn $2,000 biweekly and receive a $30,000 severance check, the payroll system looks up $30,000 on the biweekly table and withholds as if that is your regular pay.

This method is called the percentage method or wage bracket method, depending on your state. Federal withholding brackets for 2024 go up to 37% at the highest level. A single $30,000 lump sum can easily land in the 22% or 24% bracket, whereas that same $30,000 spread across 26 paychecks ($1,154 per check) would sit in a much lower bracket.

Some employers offer an alternative: you can ask them to withhold severance using the aggregate method, which combines your severance with your regular pay for the year and calculates withholding based on your actual annual income. This often results in lower withholding. However, not all employers support this option, and you must request it before the severance check is issued — after the fact, it is too late.

Social Security and Medicare taxes on severance

In addition to federal income tax withholding, your severance is subject to Social Security tax (6.2% up to an annual wage cap) and Medicare tax (1.45% with no cap). These are not income taxes; they fund your Social Security and Medicare benefits. Your employer also pays a matching amount on your behalf.

If you have already earned the Social Security wage base for the year (the cap changes annually — it was $168,600 in 2024), additional severance may not be subject to the 6.2% Social Security tax. However, Medicare tax applies to all severance with no limit. This means if you receive severance late in the year after already earning significant wages, you might see a smaller withholding percentage than someone who receives severance early in the year.

State income tax withholding on severance

Most states tax severance as ordinary income and withhold state income tax using the same lump-sum method as federal withholding. A few states — including Illinois, Mississippi, and New Hampshire — do not tax income at all, so residents in those states see lower total withholding on severance.

Some states allow employers to withhold severance differently if you request it in writing, similar to the federal aggregate method. Others require withholding based on the lump-sum amount with no exception. Check your state's tax authority website or ask your employer's payroll department what options exist in your state.

What happens when you file your tax return

The withholding taken from your severance is not your final tax bill. When you file your federal tax return the following year, you report all income you earned during that year — your regular wages, severance, bonuses, and any other income. The IRS calculates your actual tax liability based on your total income and your filing status, deductions, and credits.

If the total amount withheld from all your paychecks and severance exceeds what you actually owe, you receive a refund. If it falls short, you owe the difference. Many people who receive severance end up with a refund because the lump-sum withholding was conservative — the IRS would rather over-withhold than under-withhold.

However, if you lost your job along with the severance, your total year's income may be lower than in previous years, which could push you into a lower tax bracket overall. In that case, the refund can be substantial. Keep records of your severance check and the withholding amount (shown on your pay stub) so you have the correct figures when you file.

How to reduce withholding before severance is paid

If you know severance is coming, you have a few options to reduce the amount withheld. The most direct approach is to ask your employer's payroll department whether they can use the aggregate method to calculate withholding. Provide them with your year-to-date income and ask them to factor the severance into your actual expected annual income rather than treating it as a separate lump sum.

Another option is to adjust your Form W-4 (Employee's Withholding Certificate) before the severance is issued. You can claim additional dependents or request a flat dollar amount of extra withholding to be removed, which reduces the amount taken from your severance check. However, this requires coordination with payroll and must happen before the check is processed.

If you receive severance and lose your job in the same pay period, you have no opportunity to adjust withholding. In that case, plan to set aside money from the severance to cover any additional tax bill, or be prepared for a smaller refund than you might have expected.

Severance and unemployment benefits

Severance pay does not disqualify you from unemployment benefits in most states, but it can affect the timing of when you become may be able to access. Some states require you to exhaust severance pay before unemployment kicks in; others allow you to collect unemployment while receiving severance. A few states reduce your weekly unemployment benefit by a portion of your severance.

The tax treatment is separate: severance is taxable income, and unemployment benefits are also taxable income (though unemployment is not subject to Social Security or Medicare tax). Both are reported on your tax return, and both reduce the amount of refund you might otherwise receive.

Frequently Asked Questions

Can I get the withholding back if too much was taken from my severance?

Yes. When you file your tax return, the IRS recalculates your actual tax liability based on your total income for the year. If more was withheld than you owe, you receive a refund. This refund comes from the IRS, not your employer, and typically arrives within a few weeks of filing your return electronically.

Is severance taxed differently than a regular bonus?

Severance and bonuses are both taxed as ordinary income and both subject to the same withholding method — treated as a lump sum and calculated as if it is your regular pay period amount. The withholding rate is often similar. The main difference is that severance is usually paid when you leave the job, while bonuses are paid while you are still employed.

What if I receive severance in multiple payments instead of one lump sum?

Multiple severance payments are treated as separate paychecks and withholding is calculated on each one individually. This can result in lower total withholding than a single large payment, because each payment is smaller and may fall into a lower tax bracket. Ask your employer if they can split severance into multiple checks if you are concerned about withholding.

Do I have to pay taxes on severance if I did not work the full year?

Yes. Severance is taxable income regardless of how long you worked. However, if your total income for the year (wages plus severance) is lower than in previous years, you may fall into a lower tax bracket and owe less total tax. You still report the severance on your return, and the IRS calculates what you owe based on your actual annual income.

Can I negotiate severance to be paid after January 1st to reduce my tax bill?

You can ask, but it rarely works. Severance paid in a later tax year is taxed in that year, which could lower your current-year bill. However, most employers issue severance in the year employment ends for accounting and legal reasons. Even if you negotiate a delay, you still owe tax on the full amount — you are just moving the tax bill to the next year rather than eliminating it.
