Self-Employed Appliance Repair Technician Tax Deductions: 2026 Schedule C Guide to Parts, Miles & Tools

Published: July 23, 2026 · Reading time: 8 min

TL;DR: If you run your own appliance repair business or work on a 1099, you're self-employed — and nearly every cost of the work is deductible on Schedule C. The big ones: miles between calls at $0.725/mile on Line 9, replacement parts as COGS or supplies, meters, gauges, and tools as supplies on Line 22 (or Section 179 on Line 13 for pricier gear), EPA 608 and trade licenses on Line 23, liability insurance on Line 15, and dispatch software on Line 22. Report all income on Line 1, pay 15.3% self-employment tax, and note appliance repair generally isn't an SSTB, so you usually qualify for the 20% QBI deduction.

Diagnosing a dead compressor or a washer that won't drain is the job you trained for — the tax return is the part nobody trains you for. But if you invoice customers directly or a company pays you on a 1099 rather than a W-2, you are a business, and the return is yours to file. This guide maps every common appliance-repair write-off to the exact Schedule C line for 2026.

First, the threshold question.

Are you an independent contractor or an employee?

It decides everything below.

• Independent / own shop. If you run your own repair business or a warranty company pays you on a 1099 and you control how you work, you're self-employed. You report income and deduct expenses on Schedule C, and everything in this guide applies.
• W-2 employee of a repair company. If a company withholds taxes and controls your schedule and routes, you're an employee — and unreimbursed job costs generally aren't deductible on a federal return through 2025 law. Your best move is an accountable-plan reimbursement from the employer.

The rest of this guide assumes you're the self-employed kind.

Mileage: usually the biggest number

A service tech drives all day — between calls, to the parts counter, back to a customer for a follow-up. That travel is deductible.

• Driving between jobs, to suppliers, and on callbacks is business mileage at the 2026 rate of $0.725/mile on Line 9.
• With a qualifying home office, the drive from home to your first call and home from your last also counts — see commuting vs business miles.
• Track it with a contemporaneous mileage log showing date, destination, miles, and purpose. Personal errands don't count.

Because you're on the road constantly, mileage is often your single largest deduction — log it daily.

Parts: cost of goods sold vs. supplies

This is the part unique to a repair trade, so get it right:

• If you resell parts to customers (you buy a control board, mark it up, and bill it on the invoice), those parts are inventory — you track them as cost of goods sold (COGS) in Schedule C Part III, which flows to Line 4 and reduces gross profit. See Part III / lines 33–34.
• If you don't hold inventory and just buy materials as each job needs them, many technicians deduct them as supplies on Line 22 in the year purchased.

Either way the cost comes off your income — the difference is which section it lands in. Keep every supplier invoice and match parts to the job they went into.

Tools and test equipment

The gear that makes a diagnosis possible is deductible:

• Lower-cost tools — nut driver sets, multimeters, clamp meters, refrigerant gauges, leak detectors, cordless drills, work lights — are typically deducted in full as supplies on Line 22 in the year you buy them.
• A more expensive item — a refrigerant recovery machine, a professional diagnostic kit, or a van upfit — can be expensed in full under Section 179 on Line 13 or depreciated.

Keep the receipt and note the business use.

Licenses, certifications, and insurance

Appliance and HVAC-adjacent work is regulated, and those costs are deductible:

• EPA Section 608 certification (required to buy and handle refrigerant) → Line 23 (taxes and licenses)
• State contractor, trade, or business licenses and renewals → Line 23
• Continuing education and manufacturer training that maintains or improves your skills → Line 27a (other expenses)
• Liability, tool, and commercial-auto insurance → Line 15 (insurance)

The rest of the everyday costs

• Dispatch, scheduling, and invoicing software → Line 22
• Advertising, your website, and truck lettering → Line 8 (advertising)
• Payment-processing and lead-generation fees → Line 10 (commissions and fees)
• Shop rags, gloves, cleaners, and disposables → Line 22
• A share of your phone bill for dispatch and customer calls → business-use percentage on Line 27a or utilities
• Vehicle repairs and upkeep — deductible only if you use the actual-expense method instead of the standard mileage rate (you can't claim both on the same vehicle)

Report all income and pay self-employment tax

Every payment — check, card, app, or cash — is part of your gross receipts on Line 1. There's no cash exception; the IRS treats unreported cash jobs as underreported income. Keep a simple daily income log.

You'll owe 15.3% self-employment tax on your net profit and generally make quarterly estimated payments, since no one withholds for you.

QBI: appliance repair usually qualifies

Repair is a skilled trade, not a specified service trade or business (SSTB) like health, law, or consulting. So a self-employed technician generally qualifies for the 20% qualified business income deduction on net profit, subject to the taxable-income limits. Because QBI starts from your Line 31 net profit, complete records of parts, miles, and tools make the deduction both bigger and more defensible.

Frequently Asked Questions

What can a self-employed appliance repair technician write off on taxes?

Mileage between calls at $0.725/mile (Line 9), replacement parts as COGS or supplies, meters and tools as supplies (Line 22) or Section 179 (Line 13), EPA 608 and trade licenses (Line 23), liability insurance (Line 15), dispatch software (Line 22), advertising (Line 8), and a share of your phone bill. Independent techs report all of it on Schedule C.

How does an appliance repair technician deduct parts they install?

If you resell parts to customers, track them as cost of goods sold in Schedule C Part III. If you don't hold inventory, many techs deduct materials as supplies on Line 22. Either way they're deductible — keep supplier invoices and match parts to jobs.

Can an appliance repair tech deduct mileage between service calls?

Yes. Driving job to job, to suppliers, and on callbacks is deductible at $0.725/mile on Line 9 with a log. A qualifying home office also makes the first and last drive of the day count. Personal errands don't.

Are tools and test equipment deductible?

Yes. Lower-cost tools like meters, gauges, and drills go on Line 22 as supplies; pricier gear like a recovery machine can be expensed under Section 179 on Line 13. Keep receipts and note business use.

Does an appliance repair technician qualify for the QBI deduction?

Generally yes. Repair isn't an SSTB, so a self-employed technician usually qualifies for the 20% QBI deduction on net profit, subject to income limits. It starts from your Line 31 net profit, so complete records help.
