Incorrect Social Security Benefit Statements (Form SSA-1099)

What Happened:  Every January, the Social Security Administration (SSA) mails Form SSA-1099 to beneficiaries who received payment from the Agency during the previous calendar year.  Due to a programming error, SSA-1099’s containing incorrect information were mailed to many Missourians.  The Social Security Administration quickly fixed the problem and corrected Form SSA-1099’s were mailed on January 25, 2008.


Question 1: I just received a corrected Form SSA-1099; what should I do?

If you have not filed your Missouri income tax return or Property Tax Credit (PTC) claim, use the corrected Form SSA-1099 to prepare your income tax return or PTC claim.  If you have already filed, please use the corrected Form SSA-1099 to file an amended income tax return or PTC claim. See Question 4 and Question 5 for how to amend your return.
