Form W-4P is the form you give to the payer of your pension or annuity so they know how much federal income tax to withhold from each periodic payment. You fill in a separate one for each pension. If you don't give one, the payer withholds as if you're single with no adjustments, which may be more or less than you need.
It's the retirement version of the W-4 you filled in for your job, and it follows the same five-step layout. Everything below comes from the 2026 Form W-4P and its instructions, checked in October 2026.
W-4P or W-4R? The split people miss
| Payment | Form to use |
|---|---|
| Periodic pension or annuity payments (paid in installments at regular intervals over more than 1 year) | W-4P |
| Nonperiodic payments | W-4R |
| Eligible rollover distributions, including a lump-sum pension payment | W-4R |
| IRA distributions payable on demand | W-4R (they're treated as nonperiodic) |
| Payments to nonresident aliens and foreign estates | Neither: see Pub. 515 and Pub. 519 |
That IRA line surprises people. Even if you withdraw from an IRA every month, if the account pays on demand the IRS treats those withdrawals as nonperiodic, so the W-4P isn't the form.
The five steps
- Step 1: name, Social Security number, address and filing status. This is the only step besides signing that everyone completes.
- Step 2: only if you also have a job, more than one pension, or a spouse with a job or pension on a joint return. You either use the IRS estimator or enter income from jobs and lower-paying pensions.
- Step 3: dependents and credits, if your total income will be $200,000 or less ($400,000 or less on a joint return). The 2026 form uses $2,200 per qualifying child under 17 and $500 per other dependent, as of October 2026.
- Step 4: other income you want tax withheld on, such as interest or dividends, plus deductions beyond the standard deduction and any extra withholding per payment.
- Step 5: sign and date it, then give it to the payer, not the IRS.
Which pension carries Steps 3 and 4
The form has a rule designed to stop double counting. If you (or your spouse on a joint return) have a job, don't complete Steps 3 to 4(b) on the W-4P at all: put them on the W-4 for the job. If there's no job, complete them only on the W-4P for the pension that pays the most each year, and leave them blank on the others.
The IRS's worked examples make it concrete. Taylor, single, has a pension of $50,000 a year and a job paying $25,000 a year, as of October 2026. Taylor enters $25,000 in Step 2(b)(i) and Step 2(b)(iii) on the pension's W-4P. Sam, also single, has a $50,000 pension and a second pension of $75,000. Because the other pension pays more, Sam enters nothing in Step 2 on the $50,000 pension's form.
Opting out of withholding
You can choose no federal income tax withholding by checking the No withholding box and completing Steps 1(a), 1(b) and 5. Two limits apply:
- If you're a U.S. citizen or resident alien, you generally can't opt out for payments delivered outside the United States and its territories.
- If too little is withheld, you'll generally owe tax when you file and may owe a penalty unless you make timely estimated payments.
If you've opted out and want withholding back, you simply submit a new Form W-4P.
What happens if you don't file one
If you don't give the payer a W-4P, don't provide a Social Security number, or the IRS tells the payer your number is wrong, the payer withholds as if your filing status is single with no adjustments in Steps 2 to 4. For payments that began before 2026, your current election (or the default rate) stays in effect until you submit a new form, so there's no need to refile every year unless your situation changes.
The IRS suggests using its Tax Withholding Estimator at www.irs.gov/W4App if you're starting part way through the year, have Social Security, dividend, capital gain or business income, or have changes in marital status, jobs, dependents or deductions. If you're still working, your job's Form W-4 is where Steps 3 and 4 belong. At year end the payer reports what was paid and withheld on Form 1099-R, and if withholding doesn't cover your tax, estimated tax payments fill the gap.
If you also have Social Security or investment income
Pension withholding is often the easiest way to cover tax on income that has none withheld. Step 4(a) lets you add other income, such as interest, taxable Social Security and dividends, so the payer withholds for it too. The instructions say that if you complete Step 4(a), you likely won't have to make estimated tax payments for that income. If you have self-employment income and no job, the IRS suggests using the estimator to work out extra withholding to cover both income and self-employment tax.

The verdict
Fill in one W-4P per pension, and put the credits and deductions on only one form: the job's W-4 if you work, otherwise the biggest pension. If your withdrawals come from an IRA or a lump sum, you're on the wrong form, so ask for a W-4R. And if you're tempted to opt out, check your total tax first, because the bill and the penalty arrive together in April.
Social Security and unemployment benefits have their own withholding form, covered in our guide to voluntary withholding on benefits.
Frequently asked questions
What is Form W-4P used for?
It tells the payer of a periodic pension or annuity how much federal income tax to withhold from each payment.
Do I need a separate W-4P for each pension?
Yes. The instructions say to submit a separate Form W-4P for each pension, annuity or other periodic payment you receive.
What's the difference between W-4P and W-4R?
W-4P is for periodic payments. W-4R is for nonperiodic payments and eligible rollover distributions, including lump sums and IRA distributions payable on demand.
What happens if I don't submit a W-4P?
The payer withholds as if you're single with no adjustments. For payments that began before 2026, your current election or default rate stays in effect until you submit a new form.
Can I stop federal tax being withheld from my pension?
Generally yes, by checking the No withholding box. U.S. citizens and resident aliens generally can't opt out for payments delivered outside the United States and its territories.
Can I use Form W-4P to cover tax on my investment income?
Yes. Enter that other income in Step 4(a). The instructions say you then likely won't need estimated tax payments for it.
