Which forms report Social Security income to the IRS
If you receive Social Security benefits, the Social Security Administration sends you a Form SSA-1099 each January showing how much you were paid in the previous year. This is the form you use to report Social Security income on your federal tax return. You do not request it — SSA mails it automatically to everyone who received benefits during the year.
The form shows your gross benefit amount in Box 5. If you had Medicare premiums deducted from your benefits, those appear separately in Box 6. You will receive one SSA-1099 for each Social Security account you hold — if you receive both retirement and spousal benefits, you get one form per benefit type.
You must include this income when you file your tax return, even if no tax is owed. The IRS cross-checks SSA-1099 forms against your return, so omitting it flags your filing for review. If you did not receive your form by mid-February, contact SSA at 1-800-772-1213 or visit ssa.gov to request a replacement.
Key Takeaways
- Form SSA-1099 arrives in January and shows your total Social Security benefits for the prior year; you report this on your federal tax return.
- Whether you owe tax on Social Security depends on your combined income (adjusted gross income plus nontaxable interest plus half your Social Security benefits), not the benefit amount alone.
- If you work and earn wages, you also receive a W-2 or 1099 form from your employer, which you file alongside your SSA-1099.
- Some states do not tax Social Security; others tax it under the same rules as the federal government, so check your state's requirements separately.
- If you received benefits as a spouse or survivor, your SSA-1099 shows only your portion; your spouse or other family members receive their own forms.
How to determine if you owe federal tax on Social Security
Not all Social Security income is taxable. The IRS uses a calculation called combined income to decide whether you owe tax. Combined income is your adjusted gross income plus any nontaxable interest plus half of your Social Security benefits.
If you are single and your combined income is under $25,000, you owe no federal tax on Social Security. If it falls between $25,000 and $34,000, you may owe tax on up to 50 percent of your benefits. If it 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.
These thresholds have not changed since 1984 and do not adjust for inflation, so more people fall into taxable ranges each year. If you have other income — from a job, a pension, rental property, or investments — that income counts toward combined income even if your Social Security alone would be below the threshold.
What to do if you work and receive Social Security
If you work and receive Social Security, you will have both a W-2 (if you are an employee) or a 1099 form (if you are self-employed) and an SSA-1099. File both forms with your tax return. Your W-2 or 1099 income counts toward your combined income calculation, which determines how much of your Social Security is taxable.
If you earn wages before your full retirement age, SSA may reduce your benefits by $1 for every $2 you earn above an annual limit. In 2025, that limit is $23,400. This reduction is separate from taxes — it is a benefit rule, not a tax rule. The reduction stops the month you reach full retirement age. Report your earnings to SSA if you think you will exceed the limit; do not wait for SSA to discover it.
Once you reach full retirement age, you can earn any amount without losing benefits. Your earnings still count toward combined income for tax purposes, but they do not trigger benefit reductions.
State tax forms and requirements
Thirteen states tax Social Security benefits under their own rules: Colorado, Connecticut, Kansas, Minnesota, Missouri, Montana, Nebraska, New Mexico, Rhode Island, Utah, Vermont, and West Virginia. The other 37 states do not tax Social Security at all.
If you live in a state that taxes Social Security, you file a state income tax return and report your SSA-1099 income there as well. Some states follow the federal combined income calculation; others use different thresholds or exclude certain types of income. Contact your state tax authority or check its website to learn the specific rules for your state.
If you moved during the year, you may owe tax to two states. File a part-year resident return in the state you left and a part-year resident return in the state you moved to, reporting only the income earned in each state during the months you lived there.
Correcting errors on your SSA-1099
If your SSA-1099 shows an incorrect amount, contact SSA immediately. Call 1-800-772-1213, visit your local Social Security office, or create an account at ssa.gov and use the message center. Have your Social Security number and the form handy when you contact them.
SSA will investigate and issue a corrected form (marked as a replacement) if an error is found. Corrected forms are mailed by the end of February. If you already filed your return and the corrected form shows a different amount, you will need to file an amended return using Form 1040-X with the IRS.
Do not file your tax return until you have confirmed the amount on your SSA-1099 is correct. If you file and then discover an error, amending takes longer and may delay any refund you are owed.
Medicare premium deductions and tax reporting
If you pay Medicare Part B or Part D premiums, SSA deducts them from your benefit before sending you the payment. The gross benefit (before deductions) appears in Box 5 of your SSA-1099, and the Medicare deductions appear in Box 6. You report the gross amount as income on your tax return, not the net amount you actually received.
Medicare premiums are not deductible on your federal tax return as a medical expense, even though they were deducted from your benefits. The tax calculation uses the gross benefit amount, so the deduction does not reduce your taxable income.
If you paid Medicare premiums out of pocket (for example, if you delayed claiming Social Security and were not yet receiving benefits), you may be able to deduct them as a medical expense if your total medical expenses exceed 7.5 percent of your adjusted gross income. Keep receipts and consult a tax preparer about whether this applies to you.
Frequently Asked Questions
Do I have to file a tax return if I only receive Social Security?
Not necessarily. If Social Security is your only income and it falls below the filing threshold for your age and filing status, you do not have to file. However, if you have other income or if your combined income exceeds the thresholds listed above, you must file. When in doubt, file anyway — it takes little time and protects you from IRS penalties.
What if I did not receive my SSA-1099 by February?
Contact SSA at 1-800-772-1213 or visit ssa.gov. You can request a replacement form or ask SSA to provide the information over the phone so you can file on time. Do not delay your tax return waiting for the form to arrive; you can file with the information SSA gives you and update your return later if needed.
Can I file my taxes before I receive my SSA-1099?
You can file early if you know your benefit amount from SSA statements or your online account, but the IRS will cross-check your return against the SSA-1099 when it arrives. If the amounts do not match, your return may be delayed or flagged for review. It is safer to wait for the form.
Does my spouse need to report my Social Security on their tax return?
No. Each person reports only their own Social Security income. If you are married filing jointly, you combine your incomes to calculate whether either of you owes tax on Social Security, but each person's SSA-1099 is reported separately on the joint return.
What if I received benefits for only part of the year?
SSA still sends you an SSA-1099 showing the benefits you received during that year. Report only the amount shown on the form. If you started or stopped benefits mid-year, the form reflects only the months you received payments.
