Updated W2 for HSA - Box 12 "W"

mn001 · ‎February 22, 2026

After filing federal and state returns I received an updated W2 with small increase in the employer HSA contribution value in box 12c "W" and no change in any other data. I proceeded to edit the W2 info in TurboTax and entered the new HSA value. After entering the new HSA amount, TurboTax did not reflect any change in the refund amount originally displayed. Do I need to file an amended federal?

No, that change should not require an amended return since nothing changed with the refund/balance due.

Keep the amended W-2 in your records in the unlikely event that you receive a notice from the IRS with regard to not filing an amended return to make the change officially.
