The four boxes that affect your return
Box 3: Benefits paid
Gross Social Security benefits paid or credited during the calendar year, including amounts withheld for Medicare premiums or voluntary federal income tax.
Box 4: Benefits repaid to SSA
Social Security benefits you repaid during the year, including amounts withheld to recover an overpayment.
Box 5: Net benefits
Box 3 benefits paid minus Box 4 benefits repaid. This is the amount used to determine how much Social Security enters gross income.
Box 6: Voluntary federal income tax withheld
Federal income tax SSA withheld from benefit payments after a voluntary withholding request.
Who receives the form?
SSA generally mails or posts an SSA-1099 in January to people who received Social Security benefits in the prior year. A noncitizen may receive SSA-1042S instead. SSI-only recipients do not receive either statement because SSI is not taxable.
How to replace a missing form
