Where does a camera sensor clean go?

Updated October 10, 2026 路 Schedule C, Line 21
Short answer Schedule C, Line 21 Repairs and maintenance

A camera sensor clean belongs on Line 21, repairs and maintenance.

Why line 21

A sensor clean is maintenance on equipment you own, so it belongs on line 21 with the rest of the upkeep that keeps your gear working. It does not better the camera, restore it from a state of disrepair, or adapt it to a new use, which is the three part test that would otherwise push a cost onto Form 4562. The camera body itself is a capital asset, so keep the service bills and the purchase apart in your records.
