A $50,000 severance package after a layoff often arrives as a check for around $28,500 — and the natural question is whether that's really all of it, or whether more comes back (or gets owed) once taxes are actually filed.
Is severance taxable, and why the check is already smaller than expected
Yes — severance counts as a "supplemental wage" under IRS rules, the same category as bonuses. On $50,000 with no other adjustments, roughly $8,590 in federal withholding, $2,660 in California state withholding, and $3,825 in FICA (Social Security and Medicare) come out immediately, before the check is issued.
How is severance pay taxed, the number people mix up
The 22% federal rate withheld from severance (37% on any amount over $1 million in supplemental wages for the year) is a mandatory IRS withholding rate — not the same thing as your actual tax bracket. Whether that 22% ends up being too much or too little depends entirely on total income for the year: for someone with modest other income, the withholding is often more than what's actually owed, meaning some comes back as a refund; for someone already in a high bracket, it can fall short.

Severance is treated as wages for FICA purposes, so Social Security (6.2%, up to the 2026 wage base) and Medicare (1.45%, plus 0.9% above $200,000/$250,000) come out the same as a regular paycheck — on top of, not instead of, the federal supplemental withholding.
