Where does a laptop repair go on Schedule C?

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

A laptop screen or battery replacement belongs on Line 21, repairs and maintenance.

Why line 21

A repair keeps property you already own in ordinary efficient operating condition, which is exactly what line 21 is for. Swapping a cracked screen or a worn battery puts the machine back the way it was and adds nothing to it, so the cost is deductible in the year you pay it. Buying the laptop is the opposite answer: that is a capital asset recovered on Form 4562 and reported through line 13. If the machine is also used personally, deduct only the business share of the repair bill.

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 a laptop screen or battery replacement lands on Line 21 without you sorting it.

What a laptop screen or battery replacement is confused with

Line 13, depreciation and section 179 expense deduction
Fixing the machine you own is line 21, while buying a replacement machine is a capital asset whose cost reaches the return through line 13.
Line 18, office expense
A cheap part or accessory bought as office overhead can sit on line 18, but paying a shop to repair the machine is repairs and maintenance on line 21.

Examples that belong on line 21

The limit that applies

Only the business use percentage of a mixed use machine's repair bill is deductible.

What to keep

Keep the repair shop invoice showing the device and the work performed, plus proof of payment. Invoice wording that describes a fix rather than an upgrade is what keeps the cost on line 21 if anyone looks years later.
