Excess Social Security & RRTA Tax Withheld at a Glance

A credit for taxpayers who:

  • worked for two or more employers and had too much Social Security tax withheld from their pay; OR
  • railroad employees who had excessive tier 1 railroad retirement (RRTA) tax and tier 2 RRTA tax withheld.

This is a refundable tax credit, which means taxpayers may get money back even if they have no tax withheld.
