Amended tax return and IRMAA: get the new income used

By Elder PaperworkUpdated

Short answer

If you amended the tax return Social Security used, it can use the amended one instead. No appeal is needed.

Send it with an IRS receipt letter or an IRS transcript.

Ask within 3 calendar years after the end of that tax year.
