The 10 best tax write-offs for electrical contractors in 2026 - Section 179, bonus depreciation, vehicles, retirement plans and more from Division 26 CPA.
Division 26 CPA works exclusively with electrical contractors across North and South Carolina, and the same theme comes up every tax season: contractors overpay because no one plans for the deductions their trade actually earns. Electrical work is equipment-, vehicle- and materials-heavy — which makes it deduction-heavy when someone is paying attention all year. Here are ten of the most valuable write-offs heading into 2026.
Vans, service trucks and trailers used for the business are deductible — either by actual costs (fuel, maintenance, insurance, repairs) or the standard mileage rate. Keep a mileage log so the deduction holds up.
Wire pullers, benders, meters, drills, generators and lifts are deductible. Under Section 179 and bonus depreciation, you can often write off the full cost the year you buy them rather than depreciating over several years.
Wire, conduit, breakers, fixtures and devices are deductible job costs. Reconciling supply-house statements through weekly bookkeeping makes sure none of it slips through the cracks.
Larger purchases — bucket trucks, trailers, shop equipment — can be depreciated over time when full expensing isn't the better move. The right call depends on your year, which is exactly what tax planning sorts out.
If you run the business from a dedicated home office or shop, a portion of rent or mortgage, utilities and maintenance is deductible.
General liability, workers' compensation, commercial auto and the premiums on your bonds are deductible business expenses.
License fees through the NC Board of Examiners of Electrical Contractors or SC LLR, exam and renewal fees, and continuing-education courses are all deductible.
Payments to subcontractors are deductible — and we file the 1099s to keep you compliant.
A SEP IRA or solo 401(k) lets you set aside significant pre-tax dollars while building your own future.
Once your profit is high enough, an S-corp election can cut self-employment tax when paired with a reasonable salary. It's one of the biggest levers we model for electrical contractors.
Deductions are won during the year, not at filing. Book a consultation with Division 26 CPA and see how our packages work.
