Where do water and trash bills go on Sch C?

Updated October 10, 2026 路 Schedule C, Line 25
Short answer Schedule C, Line 25 Utilities

Water, sewer and trash for business premises belongs on Line 25, utilities.

Why line 25

Water, sewer and refuse collection at a business premises are all line 25 utilities, deductible in full. Municipal bills usually arrive as one combined invoice carrying water, sewer, storm water and sometimes a solid waste charge, and the whole thing goes on line 25 without unpicking it. Two things on these bills are not utilities. A charge that is really a property tax or a local assessment is taxes and licenses on line 23, and a dumpster or roll-off hired for a specific construction job is equipment rental, not a utility.
