Social Security taxes are withheld only if you ask for them, and only from your monthly payment

The Social Security Administration does not automatically take federal income tax out of your benefit check. You have to request it. If you do nothing, you receive your full monthly amount with no tax withheld — but you may still owe federal income tax on those benefits when you file your return.

State income tax is withheld only in a handful of states, and only if you live in one of those states and request it. The withholding process is straightforward: you fill out a form, choose a dollar amount or percentage, and SSA deducts it from your next payment onward.

Whether you should request withholding depends on your total income for the year and your tax situation. Some people owe no tax on their benefits. Others owe tax but prefer to pay it all at once when they file their return rather than have it withheld monthly.

Key Takeaways

  • Social Security does not withhold federal income tax unless you request it on Form W-4V, which you can submit online, by mail, or in person at your local Social Security office.
  • You can choose to have a flat dollar amount withheld each month, or you can request that SSA withhold 7%, 10%, 15%, or 25% of your benefit.
  • Whether your benefits are taxed depends on your combined income — Social Security benefits plus half your benefits plus other income — and your filing status.
  • If you are married and file jointly, you may owe tax on your benefits even if your Social Security income alone is modest.
  • You can change or stop withholding at any time by submitting a new Form W-4V or calling Social Security.

When Social Security benefits are taxed

Your benefits may be subject to federal income tax if your combined income exceeds a certain threshold. Combined income means your adjusted gross income plus nontaxable interest plus half of your Social Security benefits.

For 2024, the thresholds are: if you file as single and your combined income is more than $25,000, up to 50% of your benefits may be taxed. If your combined income exceeds $34,000, up to 85% of your benefits may be taxed. If you are married filing jointly, the thresholds are $32,000 and $44,000.

If you are married filing separately, the rules are stricter: any combined income above zero may trigger taxation of your benefits. Many people in this situation find it more tax-efficient to file jointly.

These thresholds have not changed since 1984, so more people are affected each year as incomes rise. If you have other income — from a job, a pension, rental property, or investments — that income counts toward the threshold even if your Social Security benefit alone is small.

How to request federal income tax withholding

You request withholding by submitting Form W-4V to the Social Security Administration. You can complete it online through your my Social Security account at ssa.gov, mail a paper copy to your local Social Security office, or bring it in person.

On the form, you choose one of four withholding rates: 7%, 10%, 15%, or 25% of your monthly benefit. You can also request a flat dollar amount instead — for example, $50 per month. The withholding starts with your next payment after SSA processes the form.

If you use the online my Social Security account, you can request withholding when ready and see it reflected in your next payment. If you mail or deliver a paper form, allow at least one week for processing.

You can change your withholding at any time by submitting a new Form W-4V. Many people adjust their withholding in the fall if they realize they will owe more or less tax than expected for the year.

State income tax withholding

Only a few states tax Social Security benefits, and the rules vary. Vermont, Colorado, Kansas, Minnesota, Missouri, Montana, Nebraska, New Mexico, Rhode Island, and Utah all tax some or all of Social Security income under certain conditions.

If you live in one of these states and your income exceeds your state's threshold, you can request state withholding on the same Form W-4V. You specify the state and the withholding amount or percentage. Not all states allow percentage-based withholding; some require a flat dollar amount.

If you move to a different state, your withholding does not automatically change. You will need to submit a new Form W-4V to adjust for your new state's rules.

What happens if you do not request withholding

If you do not request withholding, SSA sends you your full benefit with no tax taken out. You still may owe federal income tax on those benefits when you file your annual return. You can pay the tax when you file, or you can make quarterly estimated tax payments throughout the year if you expect to owe a large amount.

Some people prefer this approach because they want to keep their full monthly benefit and handle taxes once a year. Others find it easier to have tax withheld so they do not face a large bill in April.

If you owe tax but do not pay it, the IRS can explore your refund from other income to the debt, or pursue collection. Requesting withholding does not change what you owe — it just spreads the payment across the year.

How to calculate whether you will owe tax

Start by adding your adjusted gross income, any nontaxable interest, and half of your annual Social Security benefit. This is your combined income. Then compare it to the threshold for your filing status.

If your combined income is below the threshold, you owe no federal tax on your benefits. If it is above the threshold, the IRS worksheet in the instructions to Form 1040 or 1040-SR will tell you how much of your benefit is taxable.

A tax professional or the IRS Free File program can help you work through this calculation if your situation is complex — for example, if you have income from multiple sources or are married filing separately.

Changing or stopping withholding

You can increase, decrease, or stop withholding at any time. Submit a new Form W-4V with your new withholding choice, and the change takes effect with your next payment.

Many people stop withholding if their income drops — for example, if they retire from a job or sell an investment at a loss. Others increase withholding if they take a new job or realize they underestimated their tax bill.

You do not need SSA's permission to make changes. The form is yours to update whenever your situation changes.

Frequently Asked Questions

Can I request withholding if I receive benefits as a representative payee?

No. Only the person receiving the benefit can request withholding. If you are a representative payee managing benefits for someone else, that person must submit Form W-4V themselves or authorize you in writing to do so on their behalf. Contact your local Social Security office for the authorization form.

What if I request withholding but still owe tax when I file?

Withholding is an estimate. If you withheld too little, you owe the difference when you file. If you withheld too much, you receive a refund. You can adjust your withholding rate on a new Form W-4V to better match what you expect to owe next year.

Do I have to report Social Security benefits on my tax return if no tax is withheld?

You must report your benefits on your return if your combined income exceeds the threshold for your filing status, even if no tax is withheld. The IRS will compare your return to SSA's records and contact you if there is a discrepancy.

Can I request withholding for a specific dollar amount instead of a percentage?

Yes. On Form W-4V, you can enter a flat dollar amount — for example, $75 per month — instead of choosing a percentage. This is useful if you know exactly how much tax you want to pay each month.

What if I am not sure whether my benefits will be taxed?

Calculate your combined income using the worksheet in the Form 1040 instructions, or contact a tax professional. The Social Security Administration itself cannot tell you whether you will owe tax — that depends on your total income and filing status, which only you and your tax preparer know.
