How severance is taxed (and what to do about it)
By Kyle Shaddox 7 min read Money and runway
Severance feels like a single payment, but it is taxed as ordinary income the same way a paycheck is. The number on the offer letter is the gross figure. The number that hits your bank account is smaller, sometimes substantially. Knowing how it is taxed in advance prevents two predictable surprises: a smaller-than-expected deposit, and a tax bill in April that catches you off guard.
The federal rules are general and largely uniform. The state rules vary. The mechanics of withholding versus actual tax owed are where most people get confused. Here is the picture.
How is severance taxed federally?
The short version: severance is ordinary income. Your actual federal tax depends on your full-year income, not on the severance alone.
The longer version is about withholding. Severance is classified as supplemental wages by the IRS. Employers have two methods for withholding federal income tax on supplemental wages:
- The flat rate method: a flat 22 percent on supplemental wage amounts under one million dollars per year, and 37 percent on amounts above one million.
- The aggregate method: the supplemental wage is added to your regular wage for the pay period, and withholding is calculated as if the total were a normal paycheck.
Most employers use the flat 22 percent method on severance because it is simpler. That number on your pay stub is withholding, not your final tax. The IRS reconciles at tax time.
What this means in practice:
- If your effective federal rate for the year is higher than 22 percent, the 22 percent withholding is too low and you will owe at tax time.
- If your effective federal rate for the year is lower than 22 percent — which can happen if a mid-year layoff cuts your total income — the 22 percent withholding is too high and you will get a refund.
Either outcome is normal. The mistake is treating the 22 percent as a final answer and spending the gross-minus-22-percent as if it were yours to keep.
Does FICA still apply to severance?
Yes.
The employee share of FICA is 7.65 percent total — 6.2 percent for Social Security up to the wage base (171,800 dollars in 2026, indexed annually), and 1.45 percent for Medicare with no cap. The employer pays a matching share that does not appear on your check.
Higher earners may also pay the Additional Medicare Tax of 0.9 percent on wages above the threshold (200,000 dollars for single filers, 250,000 for joint, not indexed). This shows up as additional Medicare withholding on the pay stub.
For runway planning, FICA is the second-largest line on your severance pay stub after federal withholding. Account for it.
What about state tax?
State tax on severance varies widely.
A handful of states — Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, Washington, and Wyoming — have no state income tax. Severance in these states has no state withholding.
Most other states tax severance as ordinary income. Withholding rates vary:
- Some states apply a flat supplemental wage rate, typically in the 3 to 9 percent range.
- Some states use the same withholding tables as regular wages.
- A few states have specific rules for lump-sum payments that differ from both.
If you moved during the tax year, or if you worked in one state and lived in another, the state allocation can get complicated. A CPA familiar with your state is worth a 30-minute call if the severance is large or if multi-state issues are in play.
CareerCanopy is built for the stretch when these small specific decisions stack up faster than they can be sorted alone — and the cost of getting a few of them right is larger than people expect.
A worked example
A single person in a state with a 5 percent flat income tax, federal marginal rate of 24 percent, receives a 30,000 dollar lump sum severance:
- Federal withholding at the flat 22 percent supplemental rate: 6,600
- Social Security at 6.2 percent: 1,860
- Medicare at 1.45 percent: 435
- State withholding at 5 percent (varies): 1,500
Total withheld: about 10,395 dollars. Net to bank account: about 19,605 dollars.
But the actual federal tax owed on that severance, if their total full-year income leaves them in the 24 percent marginal bracket, is 24 percent of 30,000, or 7,200 dollars — not the 6,600 that was withheld. They will owe an additional 600 dollars at tax time on the severance itself, before accounting for the rest of their year.
In the opposite case — same person but the layoff drops their total annual income enough that their effective federal rate for the year is 16 percent — they would owe only 4,800 in federal tax on the severance. The 6,600 withheld would mean an 1,800 dollar refund on this slice.
The point is not that the withholding is right or wrong. It is that the withholding number is not the tax. The true-up happens in April.
Why does the first paycheck after severance feel small?
A common observation. There are two main reasons.
Withholding catches up
If a person received a large lump-sum severance at the flat 22 percent supplemental rate, the system has not yet “seen” their projected annual income at the higher level. When subsequent payroll runs occur — for a small final paycheck or a continuation of payroll for a few weeks — withholding may shift to ordinary wage tables, which for higher earners can be a higher effective rate than 22 percent. The next paycheck looks small because withholding is recalibrating.
Pre-tax deductions on a smaller gross
Pre-tax deductions for health insurance, 401(k) contributions, HSA contributions, and so on come out of gross before tax. On a smaller paycheck, these absorb a larger percentage of the take-home. If health premiums normally take 5 percent of a regular paycheck, they take a larger percentage of a smaller final one. The check shrinks more than the gross would suggest.
Neither of these is a mistake. Both feel like one.
What to do about it
A short list:
- Set aside an estimated 25 to 30 percent of severance for taxes. If you are higher-income, lean toward 30 to 35 percent. This buffer protects you in April.
- Confirm your withholding method. Pay stub should show “flat” or “supplemental” against your severance line. If it does not, ask HR.
- Run a tax projection by August. A CPA, an enrolled agent, or a careful pass through tax software with year-to-date numbers gives you a real estimate. Adjustments to estimated taxes can still be made before year-end.
- Elect 10 percent federal withholding on unemployment benefits. This is on the application form. Otherwise the benefits arrive untaxed and you owe in April.
- If you have a Roth IRA conversion under consideration, talk to a CPA about timing. A low-income year is sometimes the right year to convert traditional balances to Roth. The window may exist now that did not before.
- Adjust withholding on any remaining payroll runs if needed. Form W-4 can be updated to reduce or increase withholding on a final paycheck or on payroll continuation.
- Document the supplemental withholding on your tax return. When you file, you may need to specifically address how the severance was taxed. Tax software handles this in most cases; if your situation is unusual, a CPA hour is worth more than the software.
What about non-cash severance — equity, COBRA subsidies, outplacement?
A few quick notes:
Continued health coverage paid by the employer
Sometimes severance includes a few months of employer-paid COBRA. The value of that coverage is generally not taxable as severance to you, though specific arrangements vary. The fair value of certain non-cash benefits can be reportable. Confirm with a CPA if the package is large.
Equity vesting accelerations
If a severance package accelerates vesting of restricted stock, the value at vesting is taxable as ordinary income in the year of vesting. This can dramatically affect your full-year tax picture and is the most common source of severance-year tax surprises for tech and finance workers. A CPA conversation specifically about RSU acceleration is worth the time.
Outplacement services
The value of employer-provided outplacement services is generally not taxable to you. It does not need to be reported as income.
A short voice on the timing
Two timing notes that matter.
A severance paid in December of one year versus January of the next can shift your tax picture meaningfully. If your employer offers flexibility on payment timing, talk to a CPA before you choose. The right answer depends on whether your projected total income for each year is higher or lower.
A severance paid as a lump sum versus over several months of payroll continuation has the same total federal tax but different cash flow and different withholding mechanics. The continuation version is sometimes paired with continued benefits and is treated as ongoing W-2 wages. Read your severance agreement carefully — the timing structure is usually negotiable in the first 24 to 48 hours.
The math on severance taxation is solvable with one phone call to a competent CPA and a careful read of your pay stub. The cost of skipping that call is usually 500 to 3,000 dollars in the form of a tax surprise. The cost of the call is one hour and an hourly fee. The choice is rarely close.
