Social Security wage base: $176,100 (2025 wage base — update annually).

Amended Return Status Guide
Amended returns take far longer than original returns because they are processed by hand. Here is the typical timeline and a checklist you can track.
Typical processing timeline
-
File Form 1040-X
Mail it or e-file it, and keep a copy plus proof of mailing or the e-file confirmation.
-
About 3 weeks — intake
The IRS receives, sorts, and digitizes the return. It usually will not show up in the tracker yet.
-
8 to 12 weeks — manual review
A person reviews the changes and checks them against the original return and any supporting documents.
-
Up to 16 weeks — typical completion
Most amended returns are finished within about 16 weeks. Complex ones can take longer.
-
Check the status
Use the official IRS tool to confirm where your amended return is in the process.
