You never stop paying taxes on Social Security based on age alone

There is no age at which Social Security becomes tax-free. The amount of tax you owe on your benefits depends on your total income in a given year, not on how old you are. Some people pay federal income tax on their Social Security at 62; others never pay tax on it at age 85 or older. The difference is what else you earned that year.

The IRS uses a formula called combined income to decide whether your benefits are taxable. Combined income means your adjusted gross income plus nontaxable interest plus half of your Social Security benefits. If that number exceeds a certain threshold, you owe tax on a portion of your benefits. The threshold depends on your filing status and has not changed since 1984.

Key Takeaways

  • Social Security becomes taxable when your combined income (wages, pensions, interest, plus half your benefits) exceeds $25,000 for single filers or $32,000 for married couples filing jointly.
  • If you have no other income, you can receive up to $12,000 in Social Security per year without owing federal tax, because half your benefits count toward the threshold.
  • State taxes on Social Security vary widely — some states tax it like any other income, others exempt it entirely, and most fall somewhere in between.
  • Working while receiving Social Security can push you over the taxable threshold, even if your wages alone would not trigger a tax bill.
  • The combined income thresholds have remained the same since 1984 and do not adjust for inflation, so more beneficiaries owe tax each year.

How the combined income threshold works

The IRS divides filers into two groups. Single filers — including head of household and may have access to widow(er) — have a threshold of $25,000. Married couples filing jointly have a threshold of $32,000. Married people filing separately have a threshold of $0, meaning any combined income triggers taxation.

If your combined income is below the threshold, none of your Social Security is taxable. If it exceeds the threshold, up to 50 percent of your benefits become taxable, depending on how far over you go. If your combined income exceeds a second, higher threshold ($34,000 for single filers, $44,000 for married filing jointly), up to 85 percent of your benefits can be taxable.

The thresholds apply to your income in a single tax year. If you have a year with very low income — for example, you retire mid-year — your combined income that year might fall below the threshold even though you normally exceed it.

What counts toward combined income

Combined income includes wages, self-employment income, interest, dividends, capital gains, pensions, and distributions from retirement accounts like IRAs and 401(k)s. It also includes half of your Social Security benefits themselves. Nontaxable interest — such as interest from municipal bonds — still counts toward the threshold, even though it is not taxable income.

Some income does not count. Supplemental Security Income (SSI) is excluded. Veterans' benefits are excluded. Certain railroad retirement benefits are excluded. Roth IRA conversions and may have access to charitable distributions from IRAs have special rules and may or may not count depending on your situation.

If you are still working and receiving Social Security before your full retirement age, your wages push your combined income higher. This is one reason people often delay claiming Social Security until full retirement age — it keeps combined income lower in the years before they stop working.

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. The rules vary by state. Some use the same federal combined income thresholds; others have their own thresholds or tax all benefits above a certain age or income level.

Thirty-seven states and the District of Columbia do not tax Social Security at all. If you live in one of those states, you owe no state income tax on your benefits regardless of your combined income, though you may still owe federal tax.

If you move to a different state after you start receiving Social Security, check the tax rules in your new state. Some people move specifically to avoid state taxation of benefits, though this is only one factor in a relocation decision.

How to calculate whether you owe tax

Start with your adjusted gross income (AGI) from your tax return. Add any nontaxable interest you received. Add half of your Social Security benefits for the year. That is your combined income.

Compare your combined income to the threshold for your filing status. If you are under the threshold, stop — you owe no federal tax on your benefits. If you are over the threshold, use IRS Worksheet 1 (in the instructions for Form 1040) or IRS Publication 915 to calculate how much of your benefits are taxable. The worksheet accounts for the two-tier system and ensures you do not pay tax on more than 85 percent of your benefits.

You report taxable Social Security on Form 1040 or Form 1040-SR (for people 65 and older). The IRS sends you a Form SSA-1099 each January showing how much you received the previous year. Keep that form with your tax records.

Withholding and estimated taxes

If you owe tax on your Social Security, you can have the Social Security Administration withhold federal income tax from your monthly payment. You do this by completing Form W-4V and submitting it to your local Social Security office. You can choose to withhold 7, 10, 12, or 22 percent of your benefit.

Withholding is optional. Some people prefer to withhold and reduce their tax bill throughout the year rather than owing a large amount when they file. Others prefer to pay when they file their return. There is no penalty either way, as long as you pay what you owe by April 15.

If you have other income sources and expect to owe tax, you may need to make quarterly estimated tax payments using Form 1040-ES. This applies whether or not you withhold from Social Security.

What happens if you claim early and still work

If you claim Social Security before your full retirement age and continue working, your combined income will likely be higher because your wages count toward it. This can push you over the taxable threshold. Additionally, if you have not yet reached your full retirement age, Social Security reduces your monthly benefit by $1 for every $2 you earn above an annual limit ($23,400 in 2024, though this amount changes yearly). This earnings test applies only until you reach full retirement age.

The reduction in benefits due to earnings is separate from taxation. You may owe tax on the full benefit amount even though your actual payment was reduced. This is one reason financial advisors often recommend delaying Social Security if you plan to work.

Frequently Asked Questions

Can I avoid paying tax on Social Security by delaying my claim?

Delaying reduces your combined income in the years before you claim, which may keep you below the taxable threshold during those years. Once you claim, whether you owe tax depends on your other income, not on when you claimed. Delaying does increase your monthly benefit, which means higher combined income once you start receiving it.

Does the standard deduction protect Social Security from taxation?

No. The standard deduction applies to your overall tax liability, not to the combined income calculation. You can owe tax on Social Security even if your total income is below the standard deduction, because combined income is calculated differently.

What if I have a very high income one year — will I owe tax on 85 percent of my benefits?

Possibly. If your combined income exceeds $34,000 (single) or $44,000 (married filing jointly), up to 85 percent of your benefits become taxable. The exact amount depends on how far over the threshold you are. Use IRS Publication 915 or a tax professional to calculate the precise amount.

If I move to a state with no Social Security tax, do I stop owing federal tax?

No. Federal tax on Social Security is determined by the IRS, not by your state. Moving to a state with no state tax on Social Security saves you state tax only. You still owe federal tax if your combined income exceeds the federal threshold.

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

Not necessarily. If your only income is Social Security and it is below a certain amount (roughly $12,000 for single filers in 2024), you generally do not have to file. However, if you have other income or if you want to claim a refundable tax credit, you may want to file anyway. Check the IRS filing requirements for your situation.
