Where does a janitorial service go?

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

Routine cleaning of business premises belongs on Line 21, repairs and maintenance.

Why line 21

Routine cleaning keeps business premises in ordinary efficient operating condition, which is what line 21 covers, and the contract labor instructions tell you not to put a payment on line 11 when it is includible on line 21. So a recurring janitorial contract for a shop, studio or workshop sits naturally in repairs and maintenance. A single payment to an individual cleaner is often reported as contract labor on line 11 instead, and some filers itemise cleaning in Part V on line 27a; all three are accepted if you use one of them consistently year to year. What is not optional is the home case: cleaning a home office runs through Form 8829 and line 30.

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 routine cleaning of business premises lands on Line 21 without you sorting it.

What routine cleaning of business premises is confused with

Line 11, contract labor
A payment to an individual cleaner is reportable as contract labor on line 11, but line 11 defers to line 21 where the service is upkeep of the premises, so pick one line and stay there.
Line 30, line 30, business use of your home
If the space being cleaned is inside your home, there is no line 21 deduction and the cost enters the home office calculation on line 30.
Line 22, supplies
Mops, bags and chemicals you buy and use yourself are supplies on line 22, while paying someone to clean is a service.

What does not belong here

What to keep

Keep the cleaning contract or the monthly invoices and proof of payment, plus a W-9 for an individual cleaner. If the space is in your home, keep the square footage calculation instead, because the deduction runs through Form 8829.
