Where does equipment servicing go on Schedule C?

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

Servicing business equipment belongs on Line 21, repairs and maintenance.

Why line 21

Line 21 covers incidental repairs and maintenance that keep business property working, and a service visit is the clearest case of it. The deciding test comes from the tangible property rules: an amount has to be capitalised only if it betters the property, restores it, or adapts it to a new use, and keeping a machine running does none of the three. Routine servicing you reasonably expect to repeat during the property's class life also falls inside the routine maintenance safe harbour, which keeps it a current deduction even when the bill is large.

What servicing business equipment is confused with

Form 4562, form 4562, carried to schedule c line 13
A service visit that keeps the machine running is line 21, while rebuilding a worn out machine to like new condition is a restoration and is capitalised.
Line 9, car and truck expenses
Line 21 is property other than vehicles, so servicing a work van or truck is a car and truck expense on line 9.

Examples that belong on line 21

What does not belong here

The limit that applies

Routine maintenance safe harbour: maintenance on property other than a building stays a current deduction when you reasonably expect to perform it more than once during the property's class life.

What to keep

Keep the service invoice naming the machine and describing the work, and the service history for the asset. A dated history is what shows a cost was recurring upkeep rather than a one off restoration.
