Whether Your Social Security Is Taxed Depends on Your Other Income

Social Security benefits are taxed only if your combined income exceeds certain thresholds set by the IRS. Combined income is not the same as your Social Security payment alone — it includes wages, interest, dividends, and half of your Social Security benefits added together. Most people receiving Social Security do not pay tax on it, but if you have other income sources, you may owe tax on a portion of your benefits.

The IRS uses two income thresholds to determine how much of your benefits are taxable. For single filers, the first threshold is $25,000; for married couples filing jointly, it is $32,000. If your combined income falls below these amounts, you owe no tax on your Social Security. If it exceeds these amounts, you calculate tax using a specific formula that the IRS publishes each year.

Key Takeaways

  • Combined income includes half your Social Security benefits plus all wages, interest, dividends, and other income — not just your Social Security payment alone.
  • If your combined income is below $25,000 (single) or $32,000 (married filing jointly), your Social Security is not taxed.
  • The IRS Worksheet for calculating taxable Social Security is included in Publication 915, which you can read free from IRS.gov.
  • You can reduce your combined income by making contributions to a traditional IRA or by timing when you claim certain income sources.
  • Social Security taxes are withheld by the Social Security Administration if you request it, or you can make quarterly estimated tax payments to the IRS.

The Three Income Thresholds and How They Work

The IRS actually uses two separate thresholds, and crossing the second one means more of your benefits become taxable. 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 taxable. If your combined income exceeds the second threshold, up to 85 percent of your benefits may be taxable. These percentages are maximums — you will not necessarily owe tax on that full amount.

These thresholds have not changed since 1984, so they do not adjust for inflation. This means more people cross into the taxable range each year as their income grows.

Step-by-Step Calculation Using IRS Publication 915

The IRS provides a worksheet in Publication 915 (Social Security Benefits) that walks you through the calculation. You can read it free from IRS.gov or request a printed copy by phone at 1-800-829-3676. The worksheet takes about 10 minutes if you have your income documents ready.

Start by adding up your combined income: your wages, interest, dividends, capital gains, rental income, and half of your Social Security benefits. Write this total on line 1 of the worksheet. Next, subtract the applicable threshold ($25,000 or $32,000 depending on your filing status) on line 2. If the result is zero or negative, you stop — your Social Security is not taxed.

If the result is positive, you move to the next part of the worksheet, which compares this amount to your total Social Security benefits. The worksheet then calculates how much of your benefits are taxable using the IRS formula. The final number goes on your tax return as income.

What Counts as Combined Income

Combined income includes more than just your Social Security payment. The IRS counts wages from employment, self-employment income, interest from savings accounts and bonds, dividends from stocks, capital gains from selling investments, rental income, pension payments, and distributions from retirement accounts like IRAs and 401(k)s.

Importantly, combined income also includes half of your Social Security benefits, even though you are trying to figure out how much of that is taxable. This creates the threshold effect: as your other income rises, more of your Social Security becomes taxable.

Some income does not count toward combined income. Supplemental Security Income (SSI), Medicaid, food stamps, and housing information do not count. Tax-exempt interest from municipal bonds does not count either, though it does count toward the thresholds for determining whether you must file a return at all.

Reducing Your Combined Income Before Year-End

If you are close to a threshold, you may be able to reduce your combined income before December 31 and lower your tax bill. Contributing to a traditional IRA reduces your adjusted gross income dollar-for-dollar, which lowers your combined income. For 2024, you can contribute up to $7,000 to a traditional IRA (or $8,000 if you are age 50 or older), and the contribution is deductible if you do not have an employer retirement plan.

Timing the sale of investments can also help. If you are planning to sell stocks or mutual funds, selling in a year when your other income is lower keeps your combined income below a threshold. Similarly, if you have the option to defer a bonus, pension payment, or IRA distribution to the following year, doing so can reduce your current-year combined income.

These strategies work best if you plan ahead. If you are already in December and your combined income is higher than expected, your options are limited. Consult a tax professional if you are considering a large IRA contribution or investment sale to make sure it aligns with your overall tax situation.

How to Have Tax Withheld From Your Social Security Check

If you owe tax on your Social Security benefits, you can ask the Social Security Administration to withhold federal income tax from your monthly payment. This is simpler than making quarterly estimated tax payments and ensures you do not underpay throughout the year.

To request withholding, fill out Form W-4V (Voluntary Withholding Request) and mail it to your local Social Security office or bring it in person. You can read the form from SSA.gov. On the form, you choose a withholding rate: 7 percent, 10 percent, 12 percent, or 22 percent of your benefit amount. Social Security will begin withholding the following month.

You can change your withholding rate at any time by submitting a new Form W-4V. If you want to stop withholding, submit a new form requesting zero withholding. Keep in mind that withholding is not the same as paying your full tax bill — it is an estimate. You will still need to file a tax return to settle what you actually owe.

Frequently Asked Questions

What if I am married and my spouse has no income?

You file jointly and use the $32,000 threshold for married couples. Your spouse's lack of income does not change the threshold — it is based on your combined household income. If your combined income is below $32,000, neither of you owes tax on your Social Security.

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

No. If Social Security is your only income and it is below the filing threshold for your age and status, you do not have to file. However, you may want to file anyway if you had taxes withheld, because you could receive a refund.

Can I claim a deduction to lower my combined income?

Standard deductions lower your taxable income, but they do not lower your combined income for Social Security tax purposes. Combined income is calculated before deductions. However, contributions to a traditional IRA do lower combined income because they reduce your adjusted gross income.

What if I worked and received Social Security in the same year?

Both your wages and your Social Security count toward combined income. Add them together along with any other income sources, then use the worksheet in Publication 915 to calculate how much of your Social Security is taxable.

Do I owe state income tax on Social Security too?

That depends on your state. Most states do not tax Social Security benefits, but a few do — including Colorado, Connecticut, Kansas, Minnesota, Missouri, Montana, Nebraska, New Mexico, Rhode Island, Utah, and Vermont. Check your state's tax agency website to learn the rules where you live.
