Severance Pay Tax Calculator (2026)

How the Severance Pay Tax Calculator: Net Severance Works

This severance pay tax calculator estimates how much of a severance package you keep after federal income tax withholding, Social Security, Medicare and state tax. It also compares the flat 22% supplemental withholding that many employers use with the extra income tax the severance actually causes, so you can see whether you should expect a refund or a balance due. Enter the severance amount, the wages you already earned this year, your filing status and a state rate.

How severance pay is taxed

Severance is taxable wages, subject to federal income tax, Social Security, Medicare and state income tax in almost every state. The IRS treats it as supplemental wages, so an employer can withhold a flat 22% federal rate on amounts up to $1 million, or combine it with your regular pay and withhold using the standard tables. Severance above $1 million is withheld at 37%. Social Security tax applies only up to the wage base of $184,500, so if you have already earned most of that this year, less Social Security tax is withheld, while Medicare applies to every dollar and the 0.9% additional Medicare tax applies above $200,000.

Withholding is only a prepayment. Your real tax depends on your total income for the year, including wages before the layoff, severance, unemployment benefits and other income. Read bonus tax explained for the same withholding rules.

Worked example: $40,000 severance

A single filer has earned $60,000 this year and then receives a $40,000 severance package, for total income of $100,000 in a state with no income tax. Federal tax on $60,000 of wages would be about $5,020 and on $100,000 about $13,170, so the severance actually adds about $8,150 of tax, an effective rate of 20.4%. Flat 22% withholding takes $8,800, $650 more than needed, and Social Security and Medicare take about $3,060. After actual tax the single filer keeps about $28,790 of the severance.

Lump sum or installments

Employers may pay severance as a lump sum or as salary continuation over weeks or months. A lump sum is taxed in the year received, which can push income into a higher bracket, while installments that stretch into the next tax year can spread income across years. If you have a choice, consider whether next year's income will be lower because you are unemployed, which could make it better to receive part of the severance after January 1. Talk to a tax professional and to your employer's HR department about timing, and check how the schedule affects unemployment benefits, which some states reduce while severance is being paid.

Unused vacation, PTO payouts and other final pay

Final paychecks often include accrued vacation or paid time off, which is also taxable wages and is withheld at supplemental rates in many payroll systems. Some states require employers to pay out accrued vacation at separation, while others leave it to company policy. Add these payments to the severance amount in the calculator to see the total tax effect, and review your final stub carefully against your employment agreement and state law. Our pay stub guide explains each line.

Health insurance, retirement accounts and unemployment

Losing a job affects more than pay. Health coverage may continue through COBRA at your own expense or through the marketplace, and severance agreements sometimes include subsidized coverage. Traditional 401(k) balances can stay in the plan, be rolled into an IRA or a new employer plan, or be withdrawn, though early withdrawals can trigger a 10% penalty and taxes. Unemployment benefits are taxable federal income and are usually taxable by the state, and some states reduce benefits while you receive severance. Plan for all of these in your budget and use the W-4 withholding calculator after you start a new job.

Negotiating and reviewing a severance offer

Severance offers are often negotiable. Ask about extending pay for a longer period, subsidized health coverage, accelerated vesting of stock or retirement contributions, outplacement services and a neutral reference. Have an employment lawyer review any agreement that asks you to release legal claims, and note deadlines for review and revocation. Focus on the net amount after tax, not the headline figure, and use the calculator to compare structures before you sign.

Severance at different amounts

The table below shows how much of a severance payment a single filer keeps when earlier wages this year were $60,000.

• $10,000 of severance: flat 22% withholding is $2,200, the extra federal tax actually caused is about $1,550, Social Security and Medicare take about $765, and you keep about $7,685 after actual tax (single filer with $60,000 of earlier wages, no state tax).
• $25,000 of severance: flat 22% withholding is $5,500, the extra federal tax actually caused is about $4,850, Social Security and Medicare take about $1,913, and you keep about $18,238 after actual tax (single filer with $60,000 of earlier wages, no state tax).
• $50,000 of severance: flat 22% withholding is $11,000, the extra federal tax actually caused is about $10,350, Social Security and Medicare take about $3,825, and you keep about $35,825 after actual tax (single filer with $60,000 of earlier wages, no state tax).
• $100,000 of severance: flat 22% withholding is $22,000, the extra federal tax actually caused is about $22,114, Social Security and Medicare take about $7,650, and you keep about $70,236 after actual tax (single filer with $60,000 of earlier wages, no state tax).

The percentage taken is highest for the largest payments because more of the severance falls in the 22% and 24% brackets. Add your state tax rate in the calculator to see the full effect.

Planning the year after a layoff

A layoff changes your tax picture for the whole year and often the next. If you have less income the following year, you may benefit from deferring deductions, converting retirement funds in a low-income year or receiving part of the severance in January. If you start a new job late in the year, your new employer will withhold as if that were your only income, which can under-withhold. Complete the multiple-jobs steps on the W-4 or use the IRS Tax Withholding Estimator, and consider quarterly estimated payments if you have significant other income. Keep every pay stub, the separation agreement and any Form 1099-G for unemployment benefits so your return is accurate.

Severance in state paychecks

State income tax applies to severance in states that tax wages, and several states withhold on supplemental wages at flat rates, such as California at 6.6% and New York at a flat supplemental rate. States with no wage tax, such as Texas and Florida, tax nothing. Some states also require paying accrued vacation at separation, which adds to the final check. Use your state's calculator from the paycheck calculators by state hub to model the state portion precisely.

Severance pay and unemployment benefits

In many states, receiving a lump-sum severance payment can delay or reduce your eligibility for unemployment benefits, since some state unemployment agencies treat severance as income that must be exhausted before benefits begin, while other states don't count it against you at all. The rules vary significantly, so checking your specific state's treatment of severance is an important step before assuming you can collect both simultaneously.

If you're negotiating a severance package, it may be worth asking whether the payment can be structured as salary continuation (paid out over time as if you were still employed) versus a lump sum, since the structure can affect both your tax withholding and your unemployment eligibility timeline differently depending on your state.

Negotiating severance with taxes in mind

Because severance is typically subject to the same flat 22% federal supplemental withholding rate as bonuses, a large lump-sum severance payment can result in significant withholding upfront, even if your effective tax rate for the year ends up lower once you file your return.

Some employees negotiate for severance to be paid across two calendar years, or ask about directing part of a severance payment into a retirement account if the employer's plan allows it, both of which can help manage the tax impact of a large one-time payment.

Common mistakes with severance taxes

• Spending the gross amount. Taxes can take 30% to 40% of a severance check.
• Assuming 22% is the final rate. Your actual bracket may be higher or lower.
• Ignoring state tax. States tax severance as wages.
• Forgetting unemployment interaction. Some states reduce benefits.
• Skipping estimated taxes. A high-income year may require extra withholding.

Key takeaways

• Severance is taxable wages subject to income tax and FICA.
• Employers often withhold a flat 22% federal rate.
• Your real tax depends on total income for the year.
• Timing a payment across tax years can change the bill.
• Review health, retirement and unemployment effects before you sign.
