Can I deduct my vehicle for work as a 1099 contractor?

Yes — 1099 contractors, sole proprietors, and other self-employed taxpayers can deduct the business portion of vehicle operating costs under IRC §162. The IRS standard mileage method is the simplest route: multiply business miles by the year-specific Rev. Proc. rate.

What is the 2026 IRS standard mileage rate for business miles?

The IRS publishes the business standard mileage rate annually (and semi-annually for some years). Confirm the rate effective on the date each mile was driven on IRS Notice 2026-XX or the current Rev. Proc. Applying the wrong rate — even the wrong mid-year rate for a January-versus-July trip — is a common exam adjustment.

Can I switch between standard mileage and actual expenses?

You can switch from standard to actual in a later year, but once you use the actual method with MACRS depreciation on the vehicle, the IRS bars a return to the standard method on that same vehicle. Choose standard mileage in year one to preserve flexibility.

Are commuting miles deductible?

No — the trip between home and the first/last worksite of the day is commuting and is not deductible. Driving from home to a client site unrelated to the office is deductible as business miles if the home is the principal place of business. Allocate the commute portion carefully in the log.

What catches practitioners off guard

The risk to review

Why AI + human review matters here

The Rev. Proc. business-mileage rate changes every year (twice in some years) — apply the rate effective on the date miles were driven, not the most recent rate.
