IRS Form W-4V: Voluntary Withholding Rates, Filing, and Changes

IRS Form W-4V, the Voluntary Withholding Request, is the form you use to ask a government payer to withhold federal income tax from certain benefits, including Social Security, unemployment compensation, and Tier 1 railroad retirement. You pick one of four flat rates — 7%, 10%, 12%, or 22% — and each payment arrives with that percentage already taken out for taxes.¹ Setting up voluntary withholding this way can also spare you from making quarterly estimated tax payments, which are otherwise required whenever you expect to owe $1,000 or more at filing time.²

Which Payments Form W-4V Covers

The form works for a short, specific list of government-administered payments:¹

Unemployment compensation, including payments under the Railroad Unemployment Insurance Act. Unemployment benefits are fully taxable federally, and your state agency will not withhold federal tax unless you send in a W-4V.
Social Security retirement, survivor, and disability benefits.
Tier 1 railroad retirement benefits (the Social Security-equivalent portion).
Commodity Credit Corporation loans treated as income.
Certain crop disaster payments under the Agricultural Act of 1949 or Title II of the Disaster Assistance Act of 1988.
Dividends and other distributions from Alaska Native Corporations.

Wages from a regular employer are not on this list; those still use the standard Form W-4.

Pensions, Annuities, and IRA Distributions Use a Different Form

This is the most common mix-up. Regular pension, annuity, profit-sharing, and IRA payments use Form W-4P, which works more like the wage W-4 and lets the payer calculate a tailored withholding amount based on filing status, dependents, and other income.³ One-time or irregular retirement distributions, including eligible rollovers, use Form W-4R.⁴ Sending in a W-4V for a pension will delay your request; check which type of payment you receive before you fill anything out.

The Four Withholding Rates

You cannot request a custom dollar amount or a different percentage. Your only choices are 7%, 10%, 12%, or 22% of each payment.¹ These loosely correspond to federal income tax brackets but do not line up with any single bracket exactly.

Picking the Right Percentage

The right rate depends on your total income from every source, not just the payment being withheld on. A useful starting point is your effective tax rate from last year’s return — total tax divided by total income. If your effective rate was near 11%, then 12% will slightly overwithhold and likely produce a small refund. If Social Security is your only income and your total benefits fall below the taxable thresholds, you may owe nothing federally and can skip withholding entirely. If you have significant other income pushing you into higher brackets, 22% is often the safest choice, since overwithholding just means a refund while underwithholding can trigger a penalty. The IRS Tax Withholding Estimator at irs.gov helps model different scenarios, especially when wages or a pension are also in the mix.⁵

When None of the Four Rates Is Enough

If your real tax rate lands between the options, or exceeds 22%, voluntary withholding alone may not cover you. You can pair a W-4V election with quarterly estimated tax payments on Form 1040-ES to close the gap.² Someone in the 24% bracket could elect the 22% rate and send a small estimated payment each quarter for the difference.

How to Fill Out and Submit Form W-4V

The form is one page. Download it from irs.gov or request a copy from the agency paying your benefits.⁶ Enter your full legal name, current mailing address, and Social Security number. Check the box for the payment type you want withholding applied to, then check the box for the percentage you want. Sign and date.

One detail people miss: do not send this form to the IRS. Even though the IRS publishes it, Form W-4V goes to the agency actually paying your benefits.¹ Mailing it to the IRS accomplishes nothing.

Where Each Version Goes

Social Security benefits: the Social Security Administration. The fastest route is your my Social Security account at ssa.gov, which lets you start, stop, or change withholding online without printing anything.⁷
Unemployment compensation: your state’s unemployment agency. The mailing address is typically on your benefit determination letter or the agency’s website.
Tier 1 railroad retirement: the Railroad Retirement Board.
Commodity Credit Corporation loans, crop disaster payments, and Alaska Native Corporation distributions: the federal agency or corporation issuing the payment.

When Withholding Actually Starts

The IRS instructions tell you to ask your payer when withholding will begin.¹ For Social Security, expect roughly four to eight weeks for the SSA to update its systems. You will not get a confirmation letter; the first sign it worked is a slightly smaller deposit. If you file late in the year, withholding may not start until the following year, so a one-time estimated payment might be needed to cover the current year.

Changing or Stopping Withholding

Your election stays in place until you change it. To switch percentages, submit a new W-4V with the new rate checked. To stop withholding entirely, submit a new form and check the box to end federal income tax withholding. Processing takes about the same time as the original request. Social Security recipients can make both changes faster through the my Social Security portal than by mailing paper.⁷

Reporting and the Underpayment Penalty

At year-end, the payer sends you a statement showing benefits paid and federal tax withheld. Unemployment, CCC loans, and crop disaster payments come on Form 1099-G, with withholding in Box 4.⁸ Social Security comes on Form SSA-1099, with withholding in Box 6.⁹ You enter both the income and the withholding on your Form 1040, and the withholding is credited against your total tax the same way wage withholding is.

If you underwithhold significantly, the IRS charges an underpayment penalty that works essentially like interest on what you should have paid during the year. The rate is set quarterly.¹⁰ You avoid the penalty entirely if any of these safe harbors apply:¹¹

You owe less than $1,000 after subtracting withholding and refundable credits.
Your total payments cover at least 90% of the current year’s tax.
Your total payments equal at least 100% of last year’s tax (110% if your prior-year AGI was over $150,000, or over $75,000 if married filing separately).

The last one is easiest to work with because you already know the number. If your prior-year tax was $5,000 and your AGI was under $150,000, making sure $5,000 gets withheld or paid in during the current year protects you from a penalty even if your actual tax turns out higher.

State Taxes Are Separate

Form W-4V handles federal tax only.⁶ If you live in a state with an income tax, the federal form does nothing for your state liability. Many state unemployment agencies offer their own withholding option, but the forms and available rates vary. Most states do not tax Social Security, but if yours does, you will need to arrange state withholding or estimated payments on your own through the state tax agency.
