or W-4R details to see the withholding
Form W-4P · Form W-4R · Pub 15-T Worksheet 1B · IRC 3405 · 2026
See how much federal income tax your pension or annuity payer withholds from each payment, and what changes if you update your Form W-4P. Switch the payment type to figure the 10% default on a nonperiodic payment or IRA withdrawal, or the 20% mandatory withholding on a 401(k) or other plan distribution you could roll over.
Want to know which form applies to your payment, how to fill out Form W-4P Step 2 when you also have a job or a second pension, and when the 20% rule is too low? Read the companion guide.
Read the Pension Withholding Guide →For periodic pension and annuity payments, the payer withholds from your Form W-4P using IRS Publication 15-T Worksheet 1B: annualize the payment, add Step 4(a) other income, subtract Step 4(b) deductions and $8,600 ($12,900 married filing jointly) for 2026, apply the STANDARD withholding schedule, subtract Step 3 credits and divide by the number of payments. A single retiree with a $3,000 monthly pension and a plain W-4P has $178.33 withheld per payment. With no W-4P on file, the payer withholds as if you were single with no adjustments (as married with three allowances if your payments began before 2022). Lump sums use Form W-4R: 10% by default for nonperiodic payments and IRA withdrawals (0% to 100% allowed), and a mandatory 20% on eligible rollover distributions paid to you from a 401(k) or similar plan.
The tool follows the payer's own worksheet from IRS Publication 15-T (2026), so the result is the amount a payer's system should withhold, not your final tax bill. To estimate the tax you will actually owe on the pension for the year, use the Pension and Annuity Tax Calculator. For the rules behind each step, see the Pension Withholding Guide.
The taxable payment is multiplied by the number of payments per year (line 1c). Step 4(a) other income is added (line 1e). Step 4(b) deductions and the line 1g amount are subtracted: $12,900 if you checked married filing jointly, $8,600 otherwise. The result is the Adjusted Annual Payment Amount (line 1i). Unlike the employee worksheet, it can be negative here, because a negative figure still matters in Part II.
With no Step 2(b)(iii) amount, the Adjusted Annual Payment Amount (not less than zero) goes through the STANDARD Annual Percentage Method schedule for your filing status. With a Step 2(b)(iii) amount, the worksheet figures the tax on your other job and pension income alone (after subtracting the same $8,600 or $12,900) in Part I, figures the tax on that income plus this pension in Part II, and withholds the difference. That puts this pension's withholding in the brackets your combined income reaches.
The annual Step 3 credit amount is subtracted from the tentative annual withholding, not below zero.
The annual figure is divided by the number of payments (line 4a) and any Step 4(c) extra withholding per payment is added (line 4c). The tool rounds to the cent. If you checked No withholding, the result is $0. If there is no Form W-4P on file, the tool switches to single with no Step 2, 3 or 4 entries, as the form's instructions direct. If your payments began before 2022 and no Form W-4P was furnished, it follows Worksheet 1B lines 1j to 1l instead: married with three allowances, so the annual payments are reduced by 3 x $4,300 = $12,900 and the married filing jointly schedule applies, with no Step 3 or extra withholding.
A nonperiodic payment is withheld at 10% unless your Form W-4R line 2 sets a different whole-number rate from 0% to 100%. An eligible rollover distribution paid to you is withheld at 20%, and any W-4R rate below 20% is ignored. If you enter your other income, the tool also applies the Form W-4R method with the 2026 Marginal Rate Tables: it taxes each slice of the payment at the rate for the bracket it falls in, divides by the payment and rounds up to the next whole percent. The form's own instructions cover a payment that spans two brackets; the tool applies the same steps to every bracket the payment reaches.
| Rate | Single or married filing separately | Married filing jointly | Head of household |
|---|---|---|---|
| 0% | $0 to $7,500 | $0 to $19,300 | $0 to $15,550 |
| 10% | $7,500 to $19,900 | $19,300 to $44,100 | $15,550 to $33,250 |
| 12% | $19,900 to $57,900 | $44,100 to $120,100 | $33,250 to $83,000 |
| 22% | $57,900 to $113,200 | $120,100 to $230,700 | $83,000 to $121,250 |
| 24% | $113,200 to $209,275 | $230,700 to $422,850 | $121,250 to $217,300 |
| 32% | $209,275 to $263,725 | $422,850 to $531,750 | $217,300 to $271,750 |
| 35% | $263,725 to $648,100 | $531,750 to $788,000 | $271,750 to $656,150 |
| 37% | Over $648,100 | Over $788,000 | Over $656,150 |
Each schedule starts above zero because the 2026 standard deduction ($16,100 single, $32,200 joint, $24,150 head of household) is built in, together with the line 1g amount.
The retirees who owe the most at tax time usually did nothing wrong on their pension form. They filled it out as if the pension were their only income, then started Social Security, took required distributions from an IRA, or kept a part-time job. Each payer withheld as though it were the only one. Step 2(b) of Form W-4P exists for exactly this, and Step 4(a) is the simplest place to cover taxable Social Security and interest that have little or no withholding of their own.
The second pattern is the 20% rule on a 401(k) cash-out. Clients assume 20% settles the tax. For someone in the 22% or 24% bracket with state tax on top, it does not, and anyone under 59 and a half may also owe the 10% additional tax. When the money is going to an IRA anyway, we have the plan send it as a direct rollover so nothing is withheld and nothing has to be made up from savings within 60 days.
We set pension withholding once a year, in January, after the Social Security benefit and any required distribution amounts are known.
Submit a new Form W-4P to the payer. Use Step 2(b) for a job or a smaller pension, Step 4(a) for income with no withholding, or Step 4(c) for a flat extra amount. The Pension Withholding Guide walks through each step.
Estimate the tax on your pension for the year, including the tax-free part of each payment, with the Pension and Annuity Tax Calculator.
Find out how much of your benefit is taxable with the Social Security Tax Calculator, then add it to Step 4(a).
Check whether the 10% additional tax applies with the Early Withdrawal Penalty Calculator, because withholding does not cover it.
