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 IRS uses a formula based on your combined income — not just your benefits — to decide if any portion becomes taxable. If you have little or no other income, your benefits stay tax-free. If you have substantial income from wages, pensions, investments, or self-employment, some or all of your benefits may be subject to federal income tax.
The threshold that triggers taxation is the same for everyone, but the amount of your benefits that gets taxed depends on how much you earn above that threshold. This is different from most income: you do not pay tax on the full amount, only on the portion the IRS calculates using their formula.
Key Takeaways
- Your combined income — not your benefits alone — determines whether any benefits are taxable; combined income includes adjusted gross income, nontaxable interest, and half your Social Security benefits.
- If your combined income is below $25,000 (single) or $32,000 (married filing jointly), your benefits are not taxed.
- Between those thresholds and higher limits, up to 50 percent of your benefits may be taxable; above the higher limits, up to 85 percent may be taxable.
- You can reduce the amount of tax owed by managing other income sources, such as delaying retirement or adjusting investment withdrawals.
- The IRS sends Form SSA-1099 each January showing the benefits you received; you report this on your tax return using Form 1040.
How the IRS calculates combined income
Combined income is not the same as your adjusted gross income (AGI). The IRS starts with your AGI and adds back certain items, then adds half of your Social Security benefits. The result is your combined income, and that number determines your tax bracket for benefits.
The items added back include nontaxable interest (such as interest from municipal bonds), foreign earned income exclusions, and foreign housing exclusions. If you have a pension from work not covered by Social Security, you may also add back certain exclusions. The exact calculation depends on your situation, which is why two people with the same AGI can have different combined incomes.
The two income thresholds and what they mean
The IRS uses two thresholds. The first is called the provisional income threshold. If your combined income falls below this threshold, none of your benefits are taxed. If it exceeds the threshold, the IRS calculates how much of your benefits becomes taxable using a two-tier system.
For single filers, the first threshold is $25,000. For married couples filing jointly, it is $32,000. For married couples filing separately, it is $0 — meaning any combined income triggers taxation. These thresholds have not changed since 1984 and do not adjust for inflation each year.
The second threshold is higher. For single filers, it is $34,000. For married filing jointly, it is $44,000. Income above the second threshold triggers a different calculation that can result in more of your benefits being taxed.
How much of your benefits becomes taxable
Between the first and second threshold, up to 50 percent of your benefits may be taxable. The exact amount depends on how far your combined income exceeds the first threshold. For every dollar of combined income above the first threshold, 50 cents of benefits become taxable, up to a maximum of 50 percent of your total benefits for the year.
If your combined income exceeds the second threshold, the calculation becomes more complex. Up to 85 percent of your benefits may be taxable. This includes the 50 percent calculated above, plus an additional amount based on income above the second threshold. For every dollar above the second threshold, up to 85 cents of benefits become taxable.
The IRS publishes a worksheet each year to help you calculate this. The worksheet accounts for the specific amounts and the order in which the two tiers explore. Many tax software programs and tax preparers use this worksheet automatically.
State taxes on Social Security benefits
Thirteen states tax Social Security benefits under certain conditions: Colorado, Connecticut, Kansas, Minnesota, Missouri, Montana, Nebraska, New Mexico, Rhode Island, Utah, Vermont, and West Virginia. The rules vary by state. Some states follow the federal threshold; others have their own thresholds or tax all benefits above a certain income level.
A few states exempt benefits for residents over a certain age, usually 55 or 60. Some states exclude benefits entirely if your income is below a state-specific threshold. You will need to check your state's tax rules or consult a tax preparer familiar with your state's treatment of Social Security.
Reporting Social Security on your tax return
The Social Security Administration sends you Form SSA-1099 in January showing the benefits you received in the previous year. You use this form to report your benefits on your federal tax return. Most people report Social Security on Form 1040, the main individual income tax form.
If you are required to file a return — which depends on your total income and filing status — you must include your Social Security benefits in the calculation, even if none of them are taxable. The IRS uses the information from Form SSA-1099 to cross-check your return.
If you did not receive a Form SSA-1099 or believe it is incorrect, contact the Social Security Administration directly. Do not estimate the amount on your return.
Ways to reduce taxation of your benefits
Because taxation depends on combined income, you can sometimes reduce the amount of tax owed by managing other income sources. Delaying when you claim Social Security can lower your annual benefits income in early retirement years, which may keep your combined income below a threshold. Withdrawing less from retirement accounts in a given year, or timing withdrawals strategically, can also lower combined income.
Some people use tax-deferred accounts like traditional IRAs to reduce taxable income, though required minimum distributions (RMDs) from these accounts count toward combined income once you reach age 73. Roth conversions, which move money from traditional to Roth accounts, increase combined income in the conversion year but may reduce it in later years. These strategies require planning and depend on your specific situation.
Municipal bonds produce nontaxable interest that does not count toward combined income, unlike interest from regular savings accounts or taxable bonds. However, this strategy works only if you have substantial savings to invest and can afford to lock money into bonds.
Frequently Asked Questions
Can I avoid paying tax on Social Security by not filing a return?
No. If you owe tax on your benefits, you must file a return and pay it, regardless of whether you file voluntarily. The IRS receives a copy of your Form SSA-1099 and will contact you if you do not report the income.
What if I worked and paid Social Security taxes — do I get a refund?
No. Taxation of benefits is separate from the Social Security taxes you paid during your working years. Those taxes funded your benefits; they are not refundable. Tax on benefits you receive now is federal income tax, not Social Security tax.
Does my spouse's income count toward my combined income threshold?
Only if you file a joint return. If you are married and file separately, your spouse's income does not count toward your threshold, but your own threshold becomes $0, meaning any combined income triggers taxation. Filing jointly is usually more favorable.
If I work part-time while receiving benefits, does that income count toward the threshold?
Yes. Wages from part-time work count as part of your adjusted gross income, which is the starting point for combined income. This can push you over a threshold and make some of your benefits taxable.
Do I have to pay estimated taxes on my benefits?
Only if you expect to owe $1,000 or more in tax for the year. You can also ask the Social Security Administration to withhold federal income tax from your monthly benefit payment, which is simpler than making quarterly estimated payments.
