Tax Tips

Best Tax Deductions for Plumbers

Common Schedule C write-offs for independent plumbers and HVAC pros — tools, vehicle, supplies, and insurance.

Tools and equipment

Hand tools, pipe cutters, wrenches, and specialty equipment purchased for work are generally deductible. Keep the receipt and note the job if you use the item for both personal and business purposes.

Vehicle and mileage

Travel between job sites is usually deductible. Track miles or actual vehicle expenses (gas, maintenance, insurance).

Supplies and materials

PVC, fittings, solder, and consumables you buy for client jobs are classic Schedule C expenses. Snap a photo when you leave the supply house.

Insurance and licenses

General liability, workers comp (where required), and trade license renewals support your business and are typically deductible.
