Estimate withholding and net severance using supplemental flat rates plus state tax and optional extra withholding.
A severance package headline number can look generous, but the amount that actually lands in your bank account is smaller once taxes and withholding come out. Employers often treat severance as supplemental wages and apply flat withholding rates that don’t necessarily match your true year‑end tax bill. This severance pay tax calculator helps you see, in plain numbers, how much federal and state income tax withholding plus any extra withholding will reduce your gross severance so you can estimate your real take‑home amount.
Most U.S. employers treat severance pay as supplemental wages for withholding purposes. The IRS allows employers to use a flat supplemental withholding rate on these payments, which is commonly 22% for many income ranges (with a higher rate above certain thresholds).
The calculator starts by taking your gross severance amount and applying the federal supplemental withholding rate you enter. Federal withholding is computed as GrossSeverance × FederalRate%.
Next, it calculates state income tax withholding by multiplying the gross severance by your chosen state rate. Depending on your state, this may reflect a flat supplemental rate or an approximation of your marginal state bracket.
You can also enter an extra withholding amount in dollars if you plan to ask payroll to withhold more than the standard amounts. This is useful if you expect your overall effective tax rate to be higher than the supplemental rate and want to avoid a surprise bill at tax time.
The calculator sums federal withholding, state withholding, and any additional withholding to get a total withheld figure. Subtracting this total from your gross severance yields your estimated net severance payout.
Because it uses simple rates and does not model Social Security, Medicare, or detailed bracket mechanics, the tool is best viewed as a planning aid rather than an exact prediction of your final tax liability.
FederalWithholding = GrossSeverance × (FederalRate ÷ 100) StateWithholding = GrossSeverance × (StateRate ÷ 100) TotalWithheld = FederalWithholding + StateWithholding + AdditionalWithholding NetSeverance = GrossSeverance − TotalWithheld
This severance pay tax calculator helps you translate a headline severance package into a realistic take‑home estimate. By applying federal supplemental withholding, state income tax, and any extra withholding you choose, it shows how much of your gross severance is likely to be withheld before the check hits your account.
It is useful when you are weighing a severance agreement, planning a career transition, or coordinating with a tax professional about how much to withhold. You can quickly test different federal and state rates, or add extra withholding, to see how aggressive you want to be about covering your eventual tax bill.
Because all the assumptions are transparent, you can share the output with your advisor and adjust the inputs based on their guidance or on the specific withholding practices your employer uses.
