Home Inspector Mileage Deduction: What Counts and What Does Not

A home inspector running three inspections a day is deducting the drives between them, not just the drive to the first one. At the 2026 rates (72.5 cents per mile through June 30, then 76 cents), an inspector covering 18,000 business miles a year is looking at roughly $13,400 in deductions. The mistake that costs the most is treating the first and last drive of the day as deductible when they usually are not.

Which inspection miles are deductible

What decides it is the purpose of the drive. Distance is irrelevant. An inspector's day usually breaks into four kinds of driving, and only three of them count.

• Office or home to the first inspection: generally commuting, and not deductible.
• Between inspections: fully deductible business miles.
• To a supply house, a county records office, or a client meeting: deductible.
• Last inspection back home: generally commuting, and not deductible.

That first-and-last exclusion is what the commuting rule does, and it applies whether you drive two miles or forty. On a four-inspection day with 20 miles between each stop, you deduct the 60 miles in the middle and not the 25 at each end.

The home office exception, which changes everything

If your home qualifies as your principal place of business, the calculation flips. Trips from a qualifying home office to a work location are business travel from the first mile, which converts what would have been commuting into deductible miles.

Most independent inspectors have a genuine claim here, because the administrative core of the business really does happen at home: scheduling, report writing, invoicing, and continuing education. The requirement is that the space be used regularly and exclusively for business and be the principal place where you conduct administrative work with no other fixed location for it. Read the interaction between the home office and mileage deductions before relying on it, because the exclusivity test is stricter than most people assume.

What 18,000 miles is actually worth

The 2026 tax year has two rates because the IRS made a rare mid-year increase, so the arithmetic has to split at July 1. Take an inspector with 18,000 business miles, split roughly evenly:

• 9,000 miles at 72.5 cents (January 1 to June 30): $6,525
• 9,000 miles at 76 cents (July 1 to December 31): $6,840
• Total deduction: $13,365

For a sole proprietor in the 22 percent bracket, that deduction also reduces self-employment tax at 15.3 percent on 92.35 percent of net profit, so the combined saving is meaningfully larger than the income tax alone. Under-recording by even 15 percent of miles gives up around $2,000 of deduction.

Standard mileage or actual expenses?

Inspectors tend to drive high-mileage, moderate-value vehicles, which usually favours the standard mileage rate. The actual expense method can win where the vehicle is expensive, heavily depreciated in early years, or used for equipment hauling that drives up running costs.

One constraint decides it more often than the math does: if you want the option to switch methods later, you have to use the standard mileage rate in the first year the vehicle is placed in service. Start with actual expenses and you are locked out of the standard rate for that vehicle for good. Our comparison of the two methods works through the trade-off.

What else an inspector deducts alongside mileage

The mileage rate covers the cost of operating the vehicle: fuel, maintenance, insurance, and depreciation. It does not cover everything vehicle-adjacent.

• Tolls and parking at an inspection site: deductible separately, on top of the mileage rate
• Moisture meters, thermal cameras, ladders, and crawlspace gear: deductible as equipment
• E and O insurance, state licensing, and continuing education: deductible
• Report software subscriptions and scheduling tools: deductible

Do I need to log every single inspection drive?

You need a contemporaneous log: records made at or near the time of the drive showing date, mileage, and business purpose. A spreadsheet filled in at the end of the quarter from calendar entries is a reconstruction, and reconstructions are what fail in an audit.

What if I inspect for one firm as a contractor?

If you are paid on a 1099 you are self-employed for tax purposes and deduct on Schedule C as normal. If a firm classifies you as a W-2 employee, the federal unreimbursed employee expense deduction no longer exists, so you would need the firm to reimburse you under an accountable plan instead.

Does driving to a re-inspection count?

Yes. A return visit to the same property is business travel like any other inspection trip, subject to the same first-and-last-drive commuting analysis for the day.

Three inspections a day means dozens of short business drives a week, and short drives are the ones that never make it into a manual log. TruMile captures them automatically. Try TruMile →
