Social Security and Federal Income Tax Are Separate

Social Security benefits themselves are not taxed by the federal government in most cases. However, if you have other income — wages, pensions, interest, or self-employment earnings — you may owe federal income tax on that income, and you may be may have access to to a refund if too much was withheld. The fact that you receive Social Security does not change how the tax system works for your other income sources.

A portion of your Social Security benefits can become taxable only if your "combined income" exceeds certain thresholds. Combined income is calculated as your adjusted gross income plus nontaxable interest plus half of your Social Security benefits. For 2024, if you are single and your combined income exceeds $25,000, up to 50 percent of your benefits may be taxable. If it exceeds $34,000, up to 85 percent may be taxable. For married couples filing jointly, those thresholds are $32,000 and $44,000. These thresholds have not changed since 1984.

If you do owe tax on a portion of your benefits, the Social Security Administration does not withhold it automatically. You must either make quarterly estimated tax payments to the IRS or request that Social Security withhold federal income tax from your monthly benefit check.

Key Takeaways

  • Social Security benefits are generally not taxed unless your combined income (adjusted gross income plus half your benefits) exceeds $25,000 for single filers or $32,000 for married couples filing jointly.
  • If you have other income and too much tax was withheld, you can file a federal tax return to claim a refund, just as any other taxpayer would.
  • You can request that Social Security withhold federal income tax from your monthly check by completing Form W-4V and submitting it to your local Social Security office.
  • The IRS Free File program and AARP Tax-Aide offer free tax preparation to people over 60 with limited income, and both can help you determine whether benefits are taxable in your situation.

When Your Social Security Benefits Become Taxable

The IRS uses a specific formula to determine whether you owe tax on benefits. Start with your adjusted gross income (the income reported on your tax return before the standard deduction). Add any nontaxable interest you earned — typically from municipal bonds. Then add half of the Social Security benefits you received during the year. If that total exceeds the threshold for your filing status, a portion of your benefits is taxable.

The taxable portion is the lesser of two amounts: either 50 percent of the amount by which your combined income exceeds the first threshold, or 85 percent of your total benefits. Once combined income exceeds the second threshold, the calculation becomes more complex, but the IRS worksheet on Form 1040 or Form 1040-SR walks through it step by step.

Many people are surprised to learn that a small amount of other income — even $1 of wages or a pension — can push them over the threshold. If you are on the edge, even a year with unusually high interest income or a one-time distribution from a retirement account can trigger taxation of benefits that were not taxable in previous years.

How to Request Tax Withholding From Your Benefits

If you expect to owe federal income tax because your benefits are taxable, you can ask Social Security to withhold a flat dollar amount from your monthly check. You do this by completing Form W-4V (Voluntary Withholding Request) and submitting it to your local Social Security office in person, by mail, or through your online my Social Security account.

On the form, you specify a dollar amount to withhold each month — for example, $50 or $100. Social Security will reduce your benefit payment by that amount and send it to the IRS on your behalf. The withholding takes effect the month after Social Security receives and processes the form, which typically takes two to four weeks.

You can change or stop withholding at any time by submitting a new Form W-4V. If you want to withhold a percentage of your benefit rather than a flat amount, you cannot do that through Social Security; instead, you would need to make quarterly estimated tax payments directly to the IRS using Form 1040-ES.

Filing a Tax Return as a Social Security Recipient

You are required to file a federal income tax return if your gross income exceeds the standard deduction for your age and filing status. For 2024, the standard deduction is $14,600 for single filers age 65 and older, and $29,200 for married couples filing jointly where at least one spouse is 65 or older. If your only income is Social Security and it falls below these amounts, you generally do not have to file.

However, you may want to file even if you are not required to, because you may be may have access to to a refund. If you had federal income tax withheld from wages, a pension, or other income during the year, or if you made quarterly estimated tax payments, filing allows you to claim that back. Additionally, you may be may have access to to the Earned Income Tax Credit or the Credit for the Elderly and the Disabled, both of which require filing a return to claim.

You can file using Form 1040 or Form 1040-SR (a simplified version designed for people age 65 and older). You will need to report your Social Security benefits on lines 5a and 5b of the form, and complete the worksheet to determine the taxable portion.

Free Tax Preparation Resources for Social Security Recipients

The IRS offers free tax preparation through the Free File program to people with income below a certain threshold — for 2024, that is generally $79,000 or less in adjusted gross income. You can search for a participating provider on the IRS website and file your return online at no cost.

AARP Tax-Aide is another free resource specifically for people age 60 and older. Trained volunteers at AARP sites help you prepare and file your return in person, and they are familiar with the rules around Social Security taxation. You can find a location near you on the AARP website. Tax-Aide is available from early February through mid-April each year.

If your income is higher than the Free File threshold, you can still find low-cost tax preparation through Volunteer Income Tax Assistance (VITA) sites, which are run by nonprofits and community organizations in most areas. Search for a VITA site near you on the IRS website.

What Happens if You Owe Tax on Benefits

If you file a return and discover that you owe tax on a portion of your Social Security benefits, you owe that tax just as you would owe tax on any other income. You can pay it when you file, or if you cannot pay in full, you can set up a payment plan with the IRS.

The amount of tax you owe depends on your total taxable income and your tax bracket. It is not a flat percentage of your benefits. For example, if you are single, have $30,000 in combined income, and your benefits are partially taxable, you might owe federal income tax on $2,500 to $4,250 of your benefits, depending on the exact calculation. At the 2024 tax rates, that could mean owing $300 to $600 in federal tax, though the exact amount depends on your other income and deductions.

If you did not withhold enough during the year and owe a large amount, you may also owe a penalty for underpayment of estimated tax. However, the IRS waives this penalty if you did not have a tax filing requirement in the prior year, or if your prior-year tax was zero.

Frequently Asked Questions

Do I have to pay taxes on my entire Social Security check?

No. Social Security benefits are generally not taxed at all unless your combined income exceeds specific thresholds. Even if your benefits are partially taxable, only a portion of them — up to 85 percent — can be included in your taxable income. Most Social Security recipients pay no federal tax on their benefits.

Can I get a refund if I withheld too much tax from my Social Security?

Yes. If you requested withholding on Form W-4V and too much was withheld, you can file a tax return and claim a refund for the overpayment. The refund is processed by the IRS, typically within 21 days of filing electronically.

What if I did not withhold any tax and now I owe?

You can file a return and pay what you owe. If you cannot pay in full, you can request a payment plan from the IRS. Going forward, you can submit Form W-4V to Social Security to withhold an amount each month, or make quarterly estimated tax payments to avoid owing a large amount next year.

Does receiving Social Security affect my ability to claim other tax credits?

Social Security benefits do not disqualify you from most tax credits, but they do count toward your income for purposes of determining whether you are may be able to access. For example, the Credit for the Elderly and the Disabled has income limits, and your Social Security counts toward those limits. A tax professional or AARP Tax-Aide volunteer can help you determine which credits you may be may have access to to claim.
