Whether your Social Security is taxed depends on your other income

Social Security benefits themselves are never taxed by the federal government unless you have income from other sources. The tax applies only if your combined income exceeds a threshold set by the IRS. Combined income means your adjusted gross income plus nontaxable interest plus half your Social Security benefits.

If you have little or no other income — from a job, pension, investments, or rental property — your Social Security is not taxed at all. But if you work part-time, draw from a retirement account, or have investment income, you may owe tax on a portion of your benefits.

The thresholds are $25,000 for single filers and $32,000 for married couples filing jointly. These numbers have not changed since 1984, so more people cross them each year as wages and account balances grow.

Key Takeaways

  • Social Security is taxed only if your combined income (wages, pensions, investments, plus half your benefits) exceeds $25,000 for single filers or $32,000 for married couples filing jointly.
  • If you are below the threshold, you owe no tax on your benefits, even if you receive a large amount.
  • If you are above the threshold, you may owe tax on up to 85 percent of your benefits, depending on how far above the threshold you are.
  • You can reduce taxable income by delaying Social Security, working less, or withdrawing less from retirement accounts in a given year.

The two income thresholds and what they mean

The IRS uses two thresholds to determine how much of your benefit is taxed. The first threshold is $25,000 for single filers and $32,000 for married couples filing jointly. If your combined income is at or below this amount, none of your Social Security is taxed.

The second threshold is $34,000 for single filers and $44,000 for married couples filing jointly. If your combined income falls between the first and second threshold, up to 50 percent of your benefits may be taxed. If your combined income exceeds the second threshold, up to 85 percent of your benefits may be taxed.

The word "may" matters here: you do not automatically owe tax on the full percentage. The actual amount depends on how far above the threshold you are and the size of your benefits. The IRS worksheet on Form 1040 or a tax software program will calculate the exact amount.

How to calculate your combined income

Combined income is not the same as adjusted gross income. Start with your adjusted gross income from your tax return, then add nontaxable interest (such as interest from municipal bonds) and half of your Social Security benefits.

For example: if you have $20,000 in wages, $3,000 in nontaxable interest, and $15,000 in Social Security, your combined income is $20,000 + $3,000 + (half of $15,000) = $27,500. Since this exceeds $25,000, some of your benefits are taxed.

Certain income does not count toward combined income. Railroad retirement benefits, veterans benefits, and Supplemental Security Income (SSI) are excluded. Some people also exclude foreign earned income if they may have access to for the foreign earned income exclusion.

Strategies to reduce the tax on your benefits

If you are close to a threshold, small changes to your income can make a difference. Delaying Social Security by even one year reduces the amount you receive annually, which lowers combined income in that year and future years. Working less or taking unpaid leave can reduce wages.

Withdrawing less from IRAs, 401(k)s, or other retirement accounts in a given year also lowers combined income. If you have a choice about when to take a distribution — such as from a Roth conversion or a required minimum distribution — timing it in a lower-income year can help.

Some people use a strategy called "tax-loss harvesting" in investment accounts: selling investments at a loss to offset gains, which reduces taxable income. This is most useful if you have significant investment income, and you should consult a tax professional before doing it.

If you are married and both receive Social Security, filing separately instead of jointly may lower your combined income, though this approach has trade-offs and requires careful calculation.

What happens if you owe tax on your benefits

If you owe tax on Social Security, you can pay it when you file your tax return in April, or you can have the Social Security Administration withhold taxes from your monthly benefit. To set up withholding, complete Form W-4V and send it to your local Social Security office or submit it online through your my Social Security account.

Withholding is optional, but it prevents a large bill at tax time. The amount withheld is your choice — you can request 10, 15, 25, or 28 percent of your benefit, or a flat dollar amount.

If you did not withhold and owe tax, you can pay the full amount with your return or set up a payment plan with the IRS. Penalties and interest explore if you do not pay by the important date.

State taxes on Social Security

Thirteen states tax Social Security benefits: Colorado, Connecticut, Kansas, Minnesota, Missouri, Montana, Nebraska, New Mexico, Rhode Island, Utah, Vermont, and West Virginia. Most of these states follow the federal thresholds or use similar rules, though some have their own income limits.

A few states tax Social Security only for higher-income retirees. For example, Colorado taxes benefits only if your federal adjusted gross income exceeds $24,000 for single filers. Nebraska taxes benefits for retirees with federal adjusted gross income above $32,000.

If you live in one of these states, check your state tax return instructions or contact your state revenue office to learn the exact rules. Some states allow a deduction or credit for Social Security tax paid, which can reduce the amount you owe.

Frequently Asked Questions

Can I avoid paying tax on Social Security by not claiming it?

No. The tax is based on whether you receive the benefit, not whether you claim it on your tax return. If Social Security deposits money into your account, it counts as income for tax purposes, even if you do not report it.

Does Medicare premium withholding count toward my combined income?

No. Medicare premiums are withheld from your Social Security check, but they do not reduce your combined income for tax purposes. Your combined income is calculated before Medicare withholding.

What if I work and receive Social Security at the same time?

Your wages count as part of combined income. If you earn $30,000 and receive $20,000 in Social Security, your combined income is $30,000 + (half of $20,000) = $40,000, which exceeds both thresholds. Up to 85 percent of your benefits may be taxed.

Do I have to file a tax return if my only income is Social Security?

Not if your combined income is below the threshold. However, if you had taxes withheld from your paycheck during the year, you may want to file to claim a refund. Check the IRS filing requirements for your age and income level.

Can I deduct Social Security tax I paid?

No. Social Security tax is not deductible. However, some states offer a deduction or credit for state-level Social Security tax, so check your state rules if you live in a state that taxes benefits.
