SSA-1099 box guide
SSA-1099 Box 6: Voluntary federal income tax withheld
Federal income tax SSA withheld from benefit payments after a voluntary withholding request.
How to use Box 6
Include Box 6 with other federal withholding on Form 1040 line 25b. It is a payment toward tax, not the amount of Social Security that is taxable.
Example
With a $2,000 monthly benefit and a 10% Form W-4V election, SSA generally withholds $200 per payment and Box 6 accumulates the withholding for the year.
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.
