Where do cleaning supplies go on Schedule C?

Updated October 10, 2026 路 Schedule C, Line 22
Short answer Schedule C, Line 22 Supplies

Cleaning chemicals and cloths belongs on Line 22, supplies.

Why line 22

A cleaning business consumes its chemicals, cloths, bags and pads doing the work it bills for, which is the definition of a line 22 supply. Nothing is held as stock and nothing is sold on, so Part III does not come into it. Paying someone else to clean your own premises is a different cost and lands in repairs and maintenance or contract labor instead.
