Where does painting a rented studio go?

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

Painting a rented studio belongs on Line 21, repairs and maintenance.

Why line 21

Repainting keeps a space in the condition it was already in, so it is repairs and maintenance on line 21 even though the landlord owns the walls. Paint inside a larger project is treated differently: when it is part of a build out that betters the space or adapts it to a new use, the whole job including the paint is capitalised as a leasehold improvement. On its own, a repaint between clients or at the start of a lease is a current expense.

What painting a rented studio is confused with

Form 4562, form 4562, carried to schedule c line 13
Paint on its own is line 21, but paint that is part of a build out adding walls, wiring or new floors goes into the capitalised improvement.
Line 30, line 30, business use of your home
If the room you are painting is inside your own home, there is no full line 21 deduction and a whole house repaint reaches the return only through the home office calculation on line 30.
Line 20b, rent or lease of other business property
The rent for the studio is line 20b, while work you do inside it is line 21 or a capitalised improvement.
