Form 1040-SRU.S. Tax Return for Seniors

6a — Social Security Benefits (Gross) Updated for tax year 2025

Does this apply to you?

  • You receive Social Security retirement benefits
  • You receive Social Security survivor benefits
  • You receive Social Security disability benefits (SSDI)
  • You received a lump-sum retroactive Social Security payment
  • Your spouse receives Social Security benefits and you file jointly

Easy to overlook

Lump-sum retroactive payments are included in the current year If you received a lump-sum Social Security payment covering prior years (common when benefits are approved after an appeal), the entire lump sum appears in Box 5 of your SSA-1099 for the year you received it. You can elect to allocate portions back to earlier years using the lump-sum election method in Publication 915, which sometimes produces a lower tax. 1 IRS Publication 915 — Social Security and Equivalent Railroad Retirement Benefits

Voluntary withholding does not reduce the gross amount If you elected to have federal tax withheld from your Social Security benefits (using Form W-4V), the withheld amount is still included in the gross total on line 6a. The withholding goes on line 25b, not as a reduction to line 6a. Filers who subtract withholding from the gross amount understate their benefits. 2 General filing pattern — omitting lump-sum retroactive benefits

Watch out for this

Using Box 3 (benefits paid) instead of Box 5 (net benefits) from Form SSA-1099. Box 5 accounts for any repayments you made to the SSA during the year. Box 3 does not. If you repaid an overpayment, Boxes 3 and 5 differ, and line 6a uses Box 5.
