A missed form, a wrong basis, income that never made it onto the return. Amending is routine when it is done carefully. We prepare Form 1040-X and the schedules that change with it.

What to have ready

Frequently asked questions

Generally three years from the original due date to claim a refund. Amending to report additional income has no such limit.

Amended returns are reviewed like any other return. Filing an accurate amendment is the way to reduce exposure, not increase it.
