The IRS and partners in the Coalition Against Scam and Scheme Threats (CASST) have issued several changes for the 2025 filing season designed to help protect taxpayers against scams. One change is stepping up reviews on a variety of “other withholding” claims on Form 1040. Specifically, this refers to “Other forms” of withholding on Line 25C of Form 1040. To reduce delays in verifying the “other withholding” claimed, taxpayers are encouraged to attach supporting documentation to their returns. Key forms covered by Line 25C include Form W-2G, Certain Gambling Winnings and Form 8959, Additional Medicare Tax. We can discuss this when we prepare your tax return. Contact us for help © 2025
