Yes, federal income tax can be taken from your Social Security benefits

Social Security payments are not automatically tax-free. The federal government taxes part or all of your benefits depending on your total income for the year. This is true even if you have no other income — Social Security alone can trigger a tax bill.

The amount you owe depends on what the IRS calls your "combined income," which includes your Social Security benefits plus other earnings, interest, and certain deductions. If your combined income exceeds a threshold set by law, you will owe federal income tax on a portion of your benefits. The thresholds have not changed since 1984, so more people are affected now than when the rule began.

You can choose to have taxes withheld from your benefit payments each month, or you can pay estimated taxes quarterly, or you can wait and pay when you file your tax return. Most people who owe taxes on Social Security do not have them withheld and instead discover the bill at tax time.

Key Takeaways

  • Social Security benefits are taxable income if your combined income (benefits plus other earnings) exceeds $25,000 for a single filer or $32,000 for married filing jointly.
  • You can request federal tax withholding on your Social Security payments by completing Form W-4V and submitting it to the Social Security Administration.
  • The tax applies to a percentage of your benefits, not the full amount, and the percentage increases as your combined income rises.
  • State income tax does not explore to Social Security in most states, but thirteen states tax benefits under their own rules.

How the federal tax calculation works

The IRS uses a two-tier system to determine how much of your benefit is taxable. The first tier applies if your combined income is between the base threshold and a higher threshold. The second tier applies if your combined income exceeds the higher threshold.

For 2024, the thresholds are $25,000 for single filers and $32,000 for married couples filing jointly. If you are married filing separately, the threshold is $0 — meaning any combined income triggers taxation. Combined income includes your adjusted gross income, nontaxable interest, and one-half of your Social Security benefits.

If your combined income falls between $25,000 and $34,000 (single) or $32,000 and $44,000 (married), you may owe tax on up to 50 percent of your benefits. If your combined income exceeds $34,000 (single) or $44,000 (married), you may owe tax on up to 85 percent of your benefits. The exact amount depends on how far above the threshold you are.

The Social Security Administration does not calculate this for you. You will need to work through the calculation yourself, use tax software, or consult a tax preparer to know what you owe.

Requesting tax withholding from your payments

If you want the Social Security Administration to remove federal income tax from your monthly benefit, you must complete Form W-4V and submit it to your local Social Security office or mail it to the address on the form. You can also request withholding by calling Social Security at 1-800-772-1213.

On the form, you choose a withholding rate: 7 percent, 10 percent, 12 percent, or 22 percent of your benefit. You do not specify a dollar amount — only a percentage. If none of these rates matches what you actually owe, you can request a custom amount, but Social Security will round it to the nearest dollar.

Withholding begins the month after Social Security receives your form. If you change your mind, you can submit a new W-4V at any time to increase, decrease, or stop withholding. Keep a copy of the form for your records.

State income tax on Social Security

Most states do not tax Social Security benefits. However, thirteen states tax benefits under their own income tax rules: Colorado, Connecticut, Kansas, Minnesota, Missouri, Montana, Nebraska, New Mexico, Rhode Island, Utah, Vermont, and West Virginia.

Each state uses different thresholds and calculations. Some states exempt benefits below a certain income level, while others tax all benefits. Some states tax only the portion that is taxable under federal law, while others use their own formula. You will need to check your state's tax agency website or consult a tax preparer to know whether your state taxes your benefits and by how much.

If you live in a state that taxes Social Security, you cannot request withholding through the Social Security Administration. You will need to pay state estimated taxes on your own or handle the tax bill when you file your state return.

What happens if you do not have taxes withheld

If your benefits are taxable and you do not request withholding, you will owe the tax when you file your federal income tax return. The Social Security Administration sends you a Form SSA-1099 each January showing the total benefits you received in the previous year. You use this form to report your benefits on your tax return.

If you owe a large amount and did not have taxes withheld throughout the year, you may face a penalty for underpayment of estimated taxes. The IRS charges interest on unpaid taxes from the due date of your return. If you expect to owe, you can file Form 1040-ES to pay estimated taxes quarterly and avoid the penalty.

If you cannot pay the full amount when you file, the IRS offers payment plans and other options. Contact the IRS directly or work with a tax professional to discuss what is available to you.

Reducing your taxable Social Security income

One way to lower the amount of your benefits that is taxable is to reduce your other income. If you have earned income from work, reducing that income lowers your combined income and may move you below a tax threshold or into a lower tax bracket.

If you have investment income, you can manage when you sell investments to spread gains across multiple years rather than taking a large gain in one year. You can also direct new savings into tax-advantaged accounts if you are still working.

If you receive distributions from a traditional IRA or 401(k), you can explore whether a Roth conversion or other strategy makes sense for your situation. These decisions are complex and depend on your full financial picture, so consulting a tax professional or financial advisor is worth the cost if you have significant income from multiple sources.

Frequently Asked Questions

Do I have to pay federal income tax on Social Security if it is my only income?

It depends on how much you receive. If your combined income (which includes one-half of your Social Security benefits) is below $25,000 for a single filer, you owe no federal tax. If it is above that threshold, you may owe tax on part of your benefits even if Social Security is your only source of income.

Can I avoid taxes on Social Security by not claiming it?

No. Once you begin receiving Social Security, the benefits are taxable income whether you spend the money or not. You cannot reduce your tax bill by not depositing the check or by donating it to charity.

What if I move to a state that does not tax Social Security?

You will no longer owe state income tax on your benefits once you establish residency in that state. However, you will still owe federal income tax if your combined income exceeds the federal threshold. Some people move specifically to avoid state taxation, but the federal tax remains the same regardless of where you live.

How do I know if my state taxes Social Security?

Check your state's department of revenue or taxation website, or call their helpline. The thirteen states that tax benefits are Colorado, Connecticut, Kansas, Minnesota, Missouri, Montana, Nebraska, New Mexico, Rhode Island, Utah, Vermont, and West Virginia. All other states do not tax Social Security.

Can I change my tax withholding if my income changes during the year?

Yes. You can submit a new Form W-4V at any time to increase, decrease, or stop withholding. Changes take effect the month after Social Security receives your form. If your income drops significantly, you may want to reduce withholding to avoid overpaying taxes.
