Updated October 18, 2026. Quick answer: Step 1 of Form W-4P is where you identify yourself to the payer of your pension or annuity and pick the filing status the payer uses to compute withholding. You complete lines 1(a) and 1(b) for your name and Social Security number and check one box on line 1(c). The form then goes to the payer, not to the IRS.
What this part is for
Step 1 opens the Form W-4P certificate, which the form describes this way: “Complete Form W-4P to have payers withhold the correct amount of federal income tax from your periodic pension, annuity (including commercial annuities)”. The instructions define what counts as periodic: “Periodic payments are made in installments at regular intervals (for example, annually, quarterly, or monthly) over a period of more than 1 year.” A one-time or on-demand payment uses a different form: “Don’t use Form W-4P for a nonperiodic payment”. Those payments are handled on the Form W-4R certificate, and this page’s sibling, Form W-4R lines 1a and 1b, walks through it.
The form also says how many to file: “Submit a separate Form W-4P for each pension, annuity, or other periodic payments you receive.”
The lines, one by one
| Line | What the form says |
|---|---|
| 1(a) | “First name and middle initial Last name”. The same line also asks for an address and a city or town, state, and ZIP code. |
| 1(b) | “Social security number” |
| 1(c), first box | “Single or Married filing separately” |
| 1(c), second box | “Married filing jointly or Qualifying surviving spouse” |
| 1(c), third box | “Head of household (Check only if you’re unmarried and pay more than half the costs of keeping up a home for yourself and a qualifying individual.)” |
| Caution under 1(c) | “To claim certain credits or deductions on your tax return, you (and/or your spouse if married filing jointly) are required to have a social security number valid for employment.” “See page 2 for more information.” |
| TIP under 1(c) | “to determine the most accurate withholding for the rest of the year if you”: “are completing this form after the beginning of the year”; “expect to receive your payments only part of the year”; or “have changes during the year in your marital status”, among the other changes the TIP lists. |
The filing status you check matters because of this instruction: “Check your anticipated filing status.” “This will determine the standard deduction and tax rates used to compute your withholding.” The form’s own caution about the Social Security number is repeated in the instructions: “You (and/or your spouse if married filing jointly) must have the required social security number to claim certain credits and deductions.”
Where the number comes from
Nothing on lines 1(a) to 1(c) is calculated. The name, number and filing status come from you. For the eligibility requirements behind the credits and deductions that the Caution mentions, the instructions point elsewhere: “For additional eligibility requirements for these credits and deductions, see Pub. 501, Dependents, Standard Deduction, and Filing Information.” If you want a second opinion on how much to have withheld, use the retirement withholding calculator or read the next steps, starting with Form W-4P Step 2.
Where it goes next
The certificate is addressed to the payer: “Give Form W-4P to the payer of your pension or annuity payments.” The form adds that it “is not valid unless you sign it.” The line after the TIP says to complete the later steps “ONLY if they apply to you; otherwise, skip to Step 5.” The step-by-step pages continue with Form W-4P Step 2, Form W-4P Step 3 and Form W-4P Step 4.
If the form never reaches the payer, or the Social Security number is missing or wrong, the instructions say what happens: “If you don’t give Form W-4P to your payer, you don’t provide an SSN, or the IRS notifies the payer that you gave an incorrect SSN, then the payer will withhold tax from your payments as if your filing status is single with no adjustments in Steps 2 through 4.” The same note covers older elections: “For payments that began before 2026, your current withholding election (or your default rate) remains in effect unless you submit a new Form W-4P.” For how withheld tax is reported and claimed, see Form 1099-R box 4 and Form 1040 line 25 on your Form 1040.
Figures that depend on this step
| Where | What the IRS prints |
|---|---|
| What counts as periodic | “over a period of more than 1 year” |
| Step 3 income test, by filing status | “If your total income will be $200,000 or less ($400,000 or less if married filing jointly):” |
| Step 3(a) | “Multiply the number of qualifying children under age 17 by $2,200” |
The filing status you choose in Step 1(c) decides which of the two income figures applies. Step 3 is explained at Form W-4P Step 3.
Edition and line numbers
This page reads the 2026 version of Form W-4P, the current file irs.gov served on 2026-10-18. A payer may still be applying an earlier election; check the date and year printed on your own form. Use the line numbers and step letters printed on the copy you are holding, because a different edition can number or word them differently.
Common mistakes
- Checking the head of household box without meeting the condition printed beside it. The form says “Check only if you’re unmarried and pay more than half the costs of keeping up a home for yourself and a qualifying individual.”
- Leaving off a valid Social Security number or giving a wrong one. The instructions say the payer will withhold “as if your filing status is single with no adjustments in Steps 2 through 4.”
- Filing one certificate for several payments. The instructions say “Submit a separate Form W-4P for each pension, annuity, or other periodic payments you receive.”
