Form W-4V, the IRS "Voluntary Withholding Request," is how you ask Social Security to take federal income tax out of your monthly benefit. You can choose exactly four rates: 7%, 10%, 12%, or 22% of each payment. No other percentage and no flat dollar amount is allowed. Social Security does not withhold anything unless you ask. You can make the request online through your my Social Security account, by calling 1-800-772-1213, or by mailing or bringing a signed W-4V to your local Social Security office. Never send the form to the IRS.
This guide covers the current form (Rev. January 2026), how to fill out each line, how to choose a rate, and when withholding works better than quarterly estimated payments. The rates and steps apply to payments in 2026 and 2027. Whether your benefits are taxable at all is a separate question, covered in our guide on whether Social Security is taxable. This page is the how-to for the form itself.

The same form also covers Tier 1 railroad retirement benefits, unemployment compensation, Commodity Credit Corporation loans, certain crop disaster payments, and Alaska Native Corporation distributions. For railroad benefits, ask the Railroad Retirement Board which form it wants, since the IRS lets a payer use its own form instead.
What Each Withholding Rate Takes From Your Check
The percentage applies to each monthly payment. Here is what each rate means at a few common benefit levels. Because the withholding is a percentage, it rises on its own when your benefit goes up, including the 3.6% cost-of-living increase Social Security announced for 2027.
| Monthly benefit | 7% | 10% | 12% | 22% |
|---|
| $1,500 | $105/mo ($1,260/yr) | $150/mo ($1,800/yr) | $180/mo ($2,160/yr) | $330/mo ($3,960/yr) |
| $2,000 | $140/mo ($1,680/yr) | $200/mo ($2,400/yr) | $240/mo ($2,880/yr) | $440/mo ($5,280/yr) |
| $2,500 | $175/mo ($2,100/yr) | $250/mo ($3,000/yr) | $300/mo ($3,600/yr) | $550/mo ($6,600/yr) |
| $3,000 | $210/mo ($2,520/yr) | $300/mo ($3,600/yr) | $360/mo ($4,320/yr) | $660/mo ($7,920/yr) |
These are simple percentages of the benefit for illustration. Your benefit statement from Social Security shows the exact amount taken out, and box 6 of your Form SSA-1099 shows the year's total.
How to Choose the Right Rate
The four rates match the lower federal tax brackets (10%, 12%, 22%), plus a 7% option. Picking the rate that matches your bracket usually over-withholds, because only part of your Social Security is taxable and your deductions shelter the first dollars of income. A better method takes four steps.
- Estimate your total federal tax for the year. Use last year's return as a starting point, or run the worksheet in our Social Security taxability guide to find how much of your benefit counts as income.
- Subtract tax already being withheld elsewhere. Pensions, IRA withdrawals, and paychecks often have their own withholding.
- Divide what is left by your yearly Social Security benefit. That gives the percentage you need from Social Security.
- Pick the closest of the four rates. Round up if you want a small refund. Round down if you would rather keep more each month and owe a little in April.
For reference, these are the tax year 2026 figures that apply to the return you file in early 2027:
| Tax year 2026 figure | Single | Married filing jointly |
|---|
| Standard deduction | $16,100 | $32,200 |
| Extra standard deduction, age 65 or older | $2,050 | $1,650 per spouse who qualifies |
| Senior deduction, age 65 or older (2025 to 2028) | Up to $6,000 | Up to $6,000 per spouse who qualifies |
| 10% bracket (taxable income) | Up to $12,400 | Up to $24,800 |
| 12% bracket | $12,401 to $50,400 | $24,801 to $100,800 |
| 22% bracket | $50,401 to $105,700 | $100,801 to $211,400 |
The senior deduction shrinks once modified adjusted gross income passes $75,000 ($150,000 on a joint return). Our guide to the $6,000 senior deduction explains the phase-out. The IRS has also released tax year 2027 figures, which apply to returns filed in 2028; they are slightly higher because of inflation adjustments, so a rate chosen with 2026 numbers will be close.
Example 1: Single retiree, 67, with an IRA
Maria gets $2,000 a month from Social Security ($24,000 a year) and takes $30,000 a year from a traditional IRA with no tax withheld.
- Combined income: $30,000 + half of $24,000 = $42,000
- Taxable part of her benefit (Publication 915 worksheet): $11,300
- Adjusted gross income: $30,000 + $11,300 = $41,300
- Deductions: $16,100 standard + $2,050 age 65 + $6,000 senior = $24,150
- Taxable income: $17,150
- Tax: 10% of $12,400 ($1,240) + 12% of $4,750 ($570) = about $1,810
$1,810 divided by $24,000 is about 7.5%. At 7%, Social Security would withhold $1,680 for the year, leaving her about $130 to pay when she files. Picking 12% because she is "in the 12% bracket" would have withheld $2,880, about $1,000 more than she owes.
Example 2: Married couple, both over 65
Tom and Linda get $48,000 a year in Social Security combined ($26,000 for Tom, $22,000 for Linda) and $40,000 from a pension with no withholding.
- Combined income: $40,000 + $24,000 = $64,000
- Taxable Social Security: $23,000
- Adjusted gross income: $63,000
- Deductions: $32,200 + $3,300 (age 65, both) + $12,000 (senior, both) = $47,500
- Taxable income: $15,500, so tax is about $1,550
If both chose 7%, they would withhold $3,360, more than double what they owe. Each spouse files a separate request for their own benefit, so here Tom alone could choose 7% ($1,820 a year) and Linda could withhold nothing.
Example 3: Social Security as your only income
A single person whose only income is $22,000 a year of Social Security has combined income of $11,000, well under the $25,000 base amount. None of the benefit is taxable. Withholding here would just be an interest-free loan to the IRS that comes back as a refund.
How to Fill Out Form W-4V, Line by Line
Download the current form from irs.gov/FormW4V. It is one page.
| Line | What to enter |
|---|
| 1 | First name, middle initial, last name |
| 2 | Your Social Security number |
| 3 | Home address. Outside the U.S., write the full country name |
| 4 | Your Social Security claim number (see below) |
| 5 | Skip. This box is for unemployment benefits only |
| 6 | Check one box: 7%, 10%, 12%, or 22% |
| 7 | Check only if you want to stop withholding |
| Signature | Sign and date. The form "is not valid unless you sign it" |
Line 4 trips people up. For Social Security, the claim number is the Social Security number the benefits are paid under, followed by a letter or letter-number suffix, such as 123-45-6789A or 123-45-6789B6. The suffix shows the type of benefit. If you get spouse or survivor benefits on someone else's record, the claim number may be their Social Security number, not yours. It appears on your award letter and other notices. If you are unsure, call Social Security at 1-800-772-1213.
Check only one box across lines 5, 6, and 7.
How to Submit Your Withholding Request
You have three ways to start, change, or stop withholding. The current W-4V instructions list all three.
Online through my Social Security
- Sign in at ssa.gov/myaccount (or create an account).
- Go to the tax withholding section under your benefits.
- Choose 7%, 10%, 12%, or 22%, or choose to stop withholding.
- Save the confirmation.
This is usually the fastest route, and it skips the paper form entirely.
By phone
Call 1-800-772-1213 (TTY 1-800-325-0778), Monday through Friday, 8 a.m. to 7 p.m. Tell the representative which percentage you want withheld from each monthly payment.
By mail or in person
- Fill out and sign Form W-4V.
- Make a copy for your records.
- Mail it to, or drop it off at, your local Social Security office. Find yours with the office locator on ssa.gov.
Do not mail it to the IRS. The IRS does not process W-4V forms; only the payer does.
When withholding starts
The form tells you to ask the payer "exactly when income tax withholding will begin." In practice it often takes one or two payments to show up. Check the amount on your next deposit or your benefit notice. If nothing has changed after two months, call Social Security.
How to Change or Stop Withholding
- To change the rate: submit a new request online, by phone, or with a new W-4V with a different box checked on line 6. The new rate replaces the old one.
- To stop: check line 7 on a new W-4V, fill in lines 1 to 4, sign, and send it to Social Security. Or stop it online or by phone.
Withholding does not reset each January. Once set, it continues every year until you change it.
Withholding vs. Quarterly Estimated Payments
If you will owe federal tax, you can either withhold from your benefits or make quarterly estimated payments with Form 1040-ES. The W-4V instructions say withholding "is more convenient" for many people, but suggest estimated payments if you have other income that isn't subject to withholding.
| W-4V withholding | Quarterly estimated payments |
|---|
| Effort | Set once, runs every month | Four deadlines a year |
| Amount control | Only 7%, 10%, 12%, or 22% | Any dollar amount |
| Timing credit | Counted as paid evenly through the year, even if started late | Counted on the date you pay |
| Fixing a shortfall late in the year | Raising withholding in the fall still counts toward earlier quarters | A late payment does not cure earlier missed quarters |
| Cash flow | Smaller checks all year | You keep the money until each due date |
| Best fit | Steady benefits plus pension or IRA income | Lumpy income, such as capital gains, self-employment, or rental income |
When withholding beats estimated payments
- You keep missing deadlines. Withholding cannot be late.
- You are behind partway through the year. The IRS treats withholding as paid evenly across the year, so raising your rate in the fall can wipe out an underpayment penalty for earlier quarters. An estimated payment made in December cannot.
- Your income is predictable. Social Security plus a pension or required IRA withdrawals is easy to match with a fixed percentage.
When estimated payments make more sense
- You need a precise amount that none of the four rates hits.
- You have a one-time event, such as selling a house or stock, that would throw off a fixed monthly rate.
- You are self-employed or have rental income with no withholding at all.
The penalty rules both methods are aiming at
You generally avoid an underpayment penalty if you owe less than $1,000 when you file, or if your withholding and estimated payments cover at least 90% of this year's tax or 100% of last year's tax (110% if last year's adjusted gross income was over $150,000). Any mix of withholding and estimated payments counts.
Other places to withhold
Social Security is not the only option. Form W-4P sets withholding on pension and annuity payments, and Form W-4R sets it on IRA withdrawals and other one-time distributions, where you can choose any whole percentage from 0% to 100%. If your IRA or pension can hit an exact number and Social Security cannot, withholding there may fit better. Many retirees use both.
Special Situations
SSDI. Disability benefits use the same W-4V and the same four rates. If you expect a large back-pay award, part of it may be taxable for the year you receive it; our guide on whether SSDI is taxable covers the lump-sum election.
SSI. Supplemental Security Income is not taxable, so W-4V does not apply. If you get both SSI and Social Security, only the Social Security part can have tax withheld.
State taxes. Social Security does not withhold state income tax. If your state taxes benefits, make state estimated payments or withhold more from a pension.
At tax time. Box 6 of your Form SSA-1099 shows the federal tax withheld during the year. Report it on your Form 1040 with your other 1099 withholding.
Frequently Asked Questions
Can I have a specific dollar amount withheld from Social Security?
No. Social Security can only withhold 7%, 10%, 12%, or 22% of each payment. The form says "no other percentage or amount." If you need an exact dollar figure, combine a W-4V rate with estimated payments or with withholding from a pension or IRA.
Where do I send Form W-4V for Social Security?
Mail it to, or drop it off at, your local Social Security office. Do not send it to the IRS. You can also skip the form and make the request online through my Social Security or by calling 1-800-772-1213.
What is the claim number on line 4 of Form W-4V?
It is the Social Security number your benefits are paid under, plus a letter suffix such as "A" or "B6." It may not be your own number if you get spouse or survivor benefits. It is printed on your award letter.
Does Social Security withhold federal tax automatically?
No, with rare exceptions (such as certain benefits paid to people who are not U.S. residents). For most beneficiaries, nothing is withheld unless you ask.
What W-4V percentage should I choose?
Divide the federal tax you expect to owe, minus any tax already withheld from other income, by your yearly Social Security benefit, then pick the closest rate. Many retirees with modest pensions or IRA withdrawals land at 7% or 10%, even when their top bracket is 12%, because only part of their benefit is taxable.
How long does it take for withholding to start?
It often takes one or two payments. The IRS instructions say to ask Social Security exactly when it will begin. Check your next deposit, and call if nothing changes after two months.
Do I need a new W-4V every year?
No. Your choice stays in effect until you change it, stop it, or your payments end. Review it each fall, especially after a cost-of-living increase or a change in other income.
Can I withhold state tax from Social Security?
No. Form W-4V covers federal income tax only, and Social Security does not withhold state tax.
