Tax Deductions for Construction: What Owners Commonly Miss
Last updated: October 17, 2026Written by Shane Atkins, founder of TaxSaver Pro
Construction owners move between sites and suppliers, pay for materials out of pocket, and blend a work truck into daily life, so receipts scatter and business costs mix with personal ones. That blur is where legal write-offs quietly slip away. This guide walks through the deduction categories construction owners most often overlook.
Commonly missed deductions
01Vehicle and mileage
- What qualifies
- Truck costs and miles driven to sites and suppliers.
- What doesn't qualify
- Commuting between your home and a regular workplace, personal errands and trips, the personal-use share of a mixed-use vehicle, traffic tickets and fines, and claiming both the standard mileage rate and actual expenses for the same vehicle in the same year.
- Records to keep
- A mileage log kept as you go, showing date, destination, business purpose, and miles for each trip; odometer readings at the start and end of the year; parking and toll receipts; and receipts for gas, repairs, and insurance if you use the actual expense method.
02Tools and equipment
- What qualifies
- Heavy gear, power tools, and replacement parts.
- What doesn't qualify
- The personal-use share of tools you also use at home, tools a client reimburses you for, and items already billed into a job and counted as cost of goods.
- Records to keep
- The receipt or invoice showing date, vendor, item, and amount. For larger equipment, also record the date you started using it in the business and its business-use percentage.
- Current rate
- See the current Section 179 limit on IRS.gov.
03Home office
- What qualifies
- The space used for project management and estimating.
- What doesn't qualify
- Space also used for personal or family purposes, occasional or incidental work at home, and costs for parts of the home not used for business. W-2 employees working from home generally can't take this deduction on their federal return.
- Records to keep
- Measurements of the office and of the whole home, a photo or floor plan of the space, and, if you use the regular method, rent or mortgage interest statements, utility bills, homeowner's or renter's insurance, and repair receipts.
04Licenses and insurance
- What qualifies
- Bonds, liability, and workers' comp coverage.
- What doesn't qualify
- Personal life insurance where you or your family are the beneficiary, personal auto or homeowner's policies (those are covered through the vehicle or home office deduction), and insurance that replaces your own lost income. Self-employed health insurance is claimed separately, not as a business expense.
- Records to keep
- Policy declaration pages, premium invoices, and proof of payment.
- IRS source
- IRS Publication 535 — Business Expenses
05Job-site supplies
- What qualifies
- Materials and consumables purchased per project.
- What doesn't qualify
- Materials for personal projects, materials a client paid for directly, and materials already counted in cost of goods sold (don't deduct them twice).
- Records to keep
- Receipts or invoices listing the items, and a note of the job or project they were used on.
- IRS source
- IRS Publication 535 — Business Expenses
