SSA-1099 box guide

SSA-1099 Box 4: Benefits repaid to SSA

Social Security benefits you repaid during the year, including amounts withheld to recover an overpayment.

How to use Box 4

Box 4 reduces Box 3 to produce Box 5. If Box 4 is greater than Box 3, the normal worksheet does not apply; none of the current-year benefits are taxable, and a prior-year deduction or credit may require separate analysis.

Example

If Box 3 is $20,000 and you repaid $3,000, Box 5 is generally $17,000. That $17,000 net amount enters the taxability worksheet.

Use this box in a calculation

A single SSA-1099 field does not determine the final tax result. Combine it with filing status, other income, tax-exempt interest, deductions, and other withholding.

What to check before filing

  • A negative Box 5 can offset a spouse’s positive Box 5 on a joint return.
  • Repayments tied to benefits taxed in an earlier year may qualify for a deduction or credit.
  • Keep SSA overpayment notices and payment records with the return.
