Tax Deductions Checklist
Auto Glass Repair Tax Deductions Checklist (2026)
2026 tax deduction checklist for self-employed auto glass repair technicians. Deduct glass inventory, adhesives, tools, and mobile service costs.
Key Takeaways
- Invest in ADAS calibration equipment and training. The ability to perform post-replacement calibrations in-house generates additional revenue and the equipment cost is deductible through Section 179 or depreciation.
- If you operate a mobile service, your service van likely qualifies for enhanced Section 179 deductions if it exceeds 6,000 pounds GVWR. Check the manufacturer's GVWR rating for your vehicle.
- Track your adhesive usage per installation. High-quality urethane adhesive is expensive, and knowing your per-job material cost helps with pricing and provides granular expense documentation.
As a self-employed auto glass repair technician, you handle windshield replacements, chip repairs, and specialty glass installations, often at the customer's location. Your deductions span glass inventory, urethane adhesives, calibration tools, and a fully equipped service vehicle. This 2026 checklist covers the deductions specific to the auto glass trade.
Use this interactive checklist to review every deduction you might be eligible for. Check off items as you go to track your progress. Each deduction includes the Schedule C line where it belongs, plus a concrete example specific to your profession.

Coverage for damage caused during glass installation, including vehicle interior damage.
Example: Paying $1,500/year for a $1 million general liability policy covering installation damage.
Coverage for customer vehicles while in your care during glass service.

Common Mistakes to Avoid
Not tracking glass inventory accurately for cost of goods sold.
Use glass shop management software to record every windshield purchased and installed. Accurate inventory is critical for your COGS deduction.
Forgetting to deduct the cost of ADAS calibration equipment and training.
ADAS calibration is increasingly required after windshield replacement. Both the equipment purchase and training courses are deductible.
Missing the deduction for glass damaged or broken during installation.
Windshields that break during removal or installation are a deductible business loss. Document the damaged glass with photos and record the cost.
Not deducting adhesive and primer costs separately from glass costs.
Urethane adhesive and primers are significant consumable expenses. Track these separately to ensure you capture the full deduction.
Overlooking insurance billing software subscription fees.
Monthly fees for glass claims management software are deductible business expenses. Track these recurring charges throughout the year.
