Where do Square fees go on Schedule C?

Updated October 10, 2026 路 Schedule C, Line 10
Short answer Schedule C, Line 10 Commissions and fees

Square fees belongs on Line 10, commissions and fees.

Why line 10

Square's per-swipe and per-invoice percentage is a cost of collecting revenue, which the Schedule C instructions treat as a commission or fee on line 10. Square settles net, so put the gross ticket on line 1 and the fee here rather than reporting only what hit the bank. Hardware and monthly software plans are separate expenses and should not be mixed into the fee total. Preparers who prefer to list all card fees on line 27a as merchant fees are also within normal practice; consistency is what gets tested, not the label.

Stop looking up lines one at a time. ClaryBook totals your year into an IRS Schedule C worksheet in form order, Part I and Part II line by line, so Square fees lands on Line 10 without you sorting it.
