How the IRS Mileage Deduction Actually Works (2026)

A plain-English guide for gig drivers, contractors, and the self-employed.

Updated for the 2026 tax year

If you drive for work and you're self-employed, the IRS lets you deduct the cost of those miles — and for most people, the simplest way to do that is the standard mileage rate. The catch nobody tells you: the deduction is only as good as your records, and you can't reconstruct miles you never wrote down. Here's how it actually works.

The 2026 standard mileage rates

Each year the IRS publishes a set of cents-per-mile rates. You multiply your qualifying miles by the rate for that category. For 2026:

So 10,000 business miles in 2026 is a $7,250 deduction — not a $7,250 refund, but $7,250 knocked off the income you're taxed on. At a 22% marginal rate that's roughly $1,595 in your pocket. The charitable rate is set by statute and rarely changes; the business rate moves most years with fuel and vehicle costs.

Standard mileage vs. actual expenses

There are two ways to deduct vehicle costs, and you generally pick one:

• Standard mileage — multiply qualifying miles by the IRS rate. One number to track (miles), and the rate already bakes in gas, depreciation, insurance, and maintenance.
• Actual expenses — deduct the business-use percentage of every real cost: fuel, repairs, insurance, depreciation, etc. More paperwork, sometimes a bigger deduction for expensive vehicles.

For most gig and contract drivers, standard mileage wins on simplicity and usually on dollars too. One important rule: if you want to use standard mileage for a car you own, you generally must choose it in the first year you use the car for business.

What counts as a business mile

Business miles are trips with a business purpose — driving between job sites, to a client, to pick up supplies, or (for gig workers) while you're online and available for deliveries or rides. What doesn't count:

• Commuting from home to a regular workplace is personal, not deductible.
• Personal errands, even in the same trip, have to be separated out.

For rideshare and delivery drivers, the miles between accepting gigs — and often the miles driving to your first one and home from your last — can qualify. The rules have nuance, so when in doubt, log the trip and let your tax pro classify it.

What records the IRS actually requires

This is where most people lose money. To support a mileage deduction, the IRS wants a contemporaneous log — records made at or near the time of the trip, not reconstructed from memory in April. A defensible log shows, for each trip:

• The date
• The miles driven
• The destination or route
• The business purpose

Why "track now" isn't a sales pitch

Mileage is the one tax input you physically cannot recreate later. You can dig up a bank statement for an expense, but you can't go back to May and remember every delivery run. Every month you don't track is deduction you simply forfeit. If you wait until tax season to think about it, the money for the first three quarters of the year is already gone.

How DriveDeck handles all of this

DriveDeck is built to produce exactly the record the IRS asks for, with as little effort as possible:

• GPS or manual logging — start a trip and drive, or enter odometer readings after the fact.
• Date, distance, route, and purpose captured per trip — the four things a defensible log needs.
• Current IRS rates built in, with the correct historical rate applied automatically if you back-date a trip to a prior year.
• Tax-ready PDF and CSV reports you hand straight to your accountant, with the IRS rate citation printed on them.
• One-time $7.99 to unlock exports — no monthly subscription, unlike most mileage apps. Track free all year; pay once when you need the report.

DriveDeck is a recordkeeping tool, not tax advice. Rates and rules summarized here are for general information and can change; the IRS publishes the official figures each year. Consult a qualified tax professional about your specific situation.
