Whether you pay tax on Social Security depends on your other income
You may owe federal income tax on your Social Security benefits if your total income exceeds a certain threshold. The threshold is low — it has not changed since 1984 — and most of it comes from sources other than Social Security itself. This means even people with modest pensions, investment income, or part-time work can end up owing tax on benefits they thought were theirs to keep.
The tax applies only to the federal level. Social Security benefits are not taxed by most states, though a handful — Colorado, Connecticut, Kansas, Minnesota, Missouri, Montana, Nebraska, New Mexico, Rhode Island, Utah, and Vermont — tax them under certain conditions. The amount you owe depends on what the IRS calls your "combined income," which includes half your Social Security benefits plus all your other income sources.
Key Takeaways
- If your combined income exceeds $25,000 as a single filer or $32,000 as a married couple filing jointly, you will owe tax on at least some of your benefits.
- Combined income includes half your Social Security benefits plus all wages, pensions, interest, dividends, rental income, and other earnings.
- You can reduce the amount of tax you owe by having the Social Security Administration withhold taxes directly from your monthly payment.
- Some states tax Social Security benefits under their own rules, even though the federal threshold is the same for everyone.
How the federal tax calculation works
The IRS uses a two-tier system to determine how much of your benefit is taxable. First, add up your combined income: your adjusted gross income plus nontaxable interest plus half your Social Security benefits. Then compare that total to two thresholds.
If you file as single and your combined income is between $25,000 and $34,000, you may owe tax on up to 50 percent of your benefits. If your combined income exceeds $34,000, you may owe tax on up to 85 percent of your benefits. For married couples filing jointly, the thresholds are $32,000 and $44,000. Married people filing separately face much stricter rules and should speak with a tax professional.
The actual calculation is not straightforward — the IRS worksheet in the tax instructions walks through it step by step. Many people find it easier to use tax software or work with a tax preparer. The Social Security Administration also publishes a simplified worksheet on its website that can give you a rough estimate.
What counts as income for this calculation
Combined income includes far more than just wages. It includes pensions, 401(k) withdrawals, IRA distributions, interest from savings accounts and bonds, stock dividends, rental income, self-employment income, and capital gains. It also includes income from a spouse's IRA or pension if you file jointly.
Some income does not count. Supplemental Security Income (SSI) is excluded, as are certain veterans' benefits and some other government payments. Tax-exempt bond interest counts toward combined income even though you do not owe federal tax on it — this is one reason the calculation surprises people.
If you are still working and receiving benefits before your full retirement age, your earnings reduce your benefit amount directly. That reduction is separate from the tax calculation. Once you reach full retirement age, your earnings no longer reduce your benefit, but they still count toward combined income for tax purposes.
Withholding taxes from your benefit payment
You can ask the Social Security Administration to withhold federal income tax from your monthly benefit check. This does not change how much tax you owe — it just spreads the payment across the year instead of asking you to pay it all at tax time.
To set up withholding, complete Form W-4V and send it to your local Social Security office or mail it to the address listed on the form. You can choose to withhold 7, 10, 15, or 22 percent of your benefit. You can also change or stop withholding at any time by submitting a new form.
Withholding is optional. Some people prefer to pay the tax in a lump sum at tax time or through quarterly estimated tax payments. Others use withholding to avoid a large bill in April. There is no advantage to one method over the other — the choice depends on your cash flow and preference.
State taxation of Social Security benefits
Eleven states tax Social Security benefits under their own income tax rules. The rules vary by state and often depend on your age, income level, or whether you are a resident.
| State | Who pays tax |
|---|---|
| Colorado | Residents over 55 with income above a threshold; threshold varies by filing status |
| Connecticut | Residents with income above $75,000 (single) or $100,000 (married) |
| Kansas | Residents with income above $75,000 (single) or $100,000 (married) |
| Minnesota | Residents with income above $85,000 (single) or $110,000 (married) |
| Missouri | Residents over 59½ with income above $100,000 (single) or $150,000 (married) |
| Montana | Residents with income above $34,000 (single) or $43,000 (married) |
| Nebraska | Residents with income above $32,000 (single) or $50,000 (married) |
| New Mexico | Residents over 65 with income above $100,000 (single) or $150,000 (married) |
| Rhode Island | Residents with income above $80,000 (single) or $100,000 (married) |
| Utah | Residents with income above $25,000 (single) or $32,000 (married) |
| Vermont | Residents with income above $32,000 (single) or $50,000 (married) |
If you live in one of these states, check your state tax return instructions or contact your state revenue department to see whether you owe state tax on your benefits. Some states allow deductions or exemptions that reduce the taxable amount. A few states have reciprocal agreements with other states that affect how they tax residents who moved.
Reporting Social Security on your tax return
The Social Security Administration sends you a Form SSA-1099 each January showing the total benefits you received in the previous year. Use this form to report your benefits on your federal tax return.
If you received benefits and had other income, you will likely need to file a return even if your total income is below the standard deduction. The IRS has specific rules about when Social Security recipients must file. You can find the current thresholds in the instructions for Form 1040 or on the IRS website.
If you owe tax on your benefits and did not have withholding, you may owe estimated tax payments for the following year. Estimated payments are due quarterly — April 15, June 15, September 15, and January 15. Your tax software or preparer can help you calculate whether you need to make these payments.
Frequently Asked Questions
Can I reduce the amount of my benefits that gets taxed?
You cannot reduce your benefits themselves, but you can reduce your combined income by managing other income sources. Delaying when you withdraw from IRAs or 401(k)s, realizing capital losses to offset gains, or timing the sale of investments can lower your combined income and reduce the tax you owe on benefits.
What if I did not have taxes withheld and now owe a large amount?
You can set up withholding going forward to prevent the same situation next year. If you owe a large amount, you may be able to pay it in installments through an IRS payment plan. Contact the IRS directly or work with a tax professional to discuss your options.
Do I have to pay tax on my spouse's Social Security benefits?
No. Only the person receiving the benefits pays tax on them. However, if you file jointly, your spouse's benefits count toward your combined income, which may push you into a higher tax bracket on your own income.
Does working part-time while receiving Social Security affect my taxes?
Yes. Your wages count toward combined income for tax purposes. If you are under full retirement age, your earnings also reduce your benefit amount directly — the Social Security Administration withholds $1 in benefits for every $2 you earn above an annual limit, which changes each year.
What if I moved to a state that taxes Social Security?
You will owe state tax on your benefits under that state's rules, even if you did not owe state tax in your previous state. Some states have transition rules for recent residents. Contact your new state's revenue department to learn what you owe for the year you moved.
