In the United States, severance pay is generally taxable federal income and is treated as wages for payroll taxes. An employer may withhold federal income tax using rules for supplemental wages, but the amount withheld is only a prepayment—not necessarily the tax you will ultimately owe.
How severance is taxed federally
The IRS says you must include severance pay and payments for cancellation of an employment contract in income. Severance is also treated as wages for payroll purposes, so it is subject to Social Security and Medicare taxes, federal income-tax withholding, and federal unemployment tax (FUTA). IRS Publication 525 (2025) covers the income-inclusion rule; IRS Publication 15 (2026) describes payroll-tax treatment.
These are separate issues: payroll taxes and income-tax withholding may be deducted from a check, while your final federal income-tax liability is determined on your annual tax return.
Why the federal withholding on a severance check can look high
Employers classify severance as supplemental wages. The federal withholding method depends partly on whether the severance is identified separately from regular wages. Under IRS Publication 15 (2026), an employer may use the optional flat 22% withholding method for qualifying supplemental wages that are separately identified. If supplemental wages paid by that employer to the employee exceed $1 million during the calendar year, the amount above $1 million is subject to mandatory 37% withholding.
#1 Best Overall
If supplemental wages and regular wages are paid together without specifying their separate amounts, the employer withholds as if the combined payment were one regular payroll-period payment. The 22% and 37% figures are withholding rules, not universal final tax rates on severance; the $1 million threshold affects withholding, not whether severance is taxable.
Withholding is not your final tax bill
Withholding is an advance payment credited toward the tax calculated on your annual return. Your final result depends on your overall income and tax situation, not just the severance check. Withholding can be higher or lower than the amount needed for the year.
Rank #2
IRS Publication 505 (2026) explains that withholding depends on factors including pay, payroll period, and Form W-4 information. If you expect withholding to be insufficient, you may need to make estimated tax payments. Publication 505 explains withholding and estimated-tax rules.
Severance is different from unemployment compensation
Severance is employer-paid compensation; unemployment compensation is a separate category with its own reporting and withholding rules. The IRS says unemployment compensation is generally reported on Form 1099-G, though tax treatment can vary by the program paying the benefit. Federal tax may be paid through voluntary withholding using Form W-4V or through quarterly estimated payments. See the IRS guidance on unemployment compensation.

If you accept reduced severance in exchange for outplacement services such as résumé writing or interview training, the IRS says you must include the unreduced severance amount in income. The fact that some of the package is provided as a service rather than cash does not, by itself, lower the amount included. IRS Publication 525 addresses this arrangement.

- Review your pay statement. Check how the payment is described and whether severance is shown separately from regular wages.
- Ask payroll which withholding method was used. The supplemental-wage method depends on how the payment was identified and paid.
- Separate withholding from taxability. A withholding percentage does not establish your final tax rate or refund.
- Consider your full-year picture. If your expected withholding is short, review estimated payments and Form W-4 guidance in IRS Publication 505.
- Check state and local rules separately. Treatment depends on your jurisdiction and circumstances; consult your state tax agency for applicable rules.
If your severance agreement includes unusual payment terms, services, or other compensation, a qualified tax professional can assess how the arrangement fits your full tax situation.
