Vehicle Mileage Deduction

2026 standard mileage rate

The IRS sets the standard mileage rate each year, and for 2026 it's $0.655 per mile. That number isn't arbitrary — it's calculated from an annual study of what it actually costs to own and operate a vehicle in the US: fuel, maintenance, depreciation, insurance, registration and fees, and finance charges. The 2026 rate reflects continued elevated vehicle costs, particularly around fuel and insurance premiums.

The standard mileage rate bundles everything into one per-mile number. You don't separately deduct gas, oil changes, tire replacements, insurance, or depreciation — it's all baked into the $0.655 rate. The one exception: you can still deduct parking fees, tolls, and the business-use portion of vehicle loan interest and personal property tax on top of the standard mileage rate. Those aren't included.

Historically, the rate fluctuates with gas prices and broader vehicle costs. It was $0.655 in 2025 too, held steady after a series of mid-year adjustments during the volatile fuel price period of 2022–2023. For comparison, 2022 started at $0.585 but got bumped to $0.625 mid-year — the first mid-year adjustment since 2011.

What counts as business miles

Not every mile you drive is deductible. Here's what the IRS considers legitimate business mileage:

• Driving between two work locations. If you work at two different offices, client sites, or job sites, the miles between them count. A contractor driving from one job site to another across town — that's business mileage.
• Driving from your home office to meet a client. If you have a qualifying home office (see our home office deduction guide), any trip from that office to a client meeting or work site is business mileage. This is a big one — commuters lose out, but home-office filers convert what would be commuting miles into deductible miles.
• Trips to a temporary work location. If you normally work at one office but drive to a different site for a one-week project, the miles between your home and that temporary location are deductible — regardless of whether you have a home office. The IRS defines "temporary" as a location you expect to work at for less than a year.
• Errands that are ordinary and necessary for your business. Driving to the bank to deposit client checks, picking up supplies at Office Depot, dropping off packages at the post office for your Etsy shop. These are business miles.
• Driving for ride-share or delivery work. All miles driven while the app is on and you're available for trips — including the miles between dropping off one passenger and picking up the next. For delivery drivers, miles driven to the restaurant and from the restaurant to the customer both count.
• Business travel away from home. Driving to the airport for a business trip, or driving your car to a multi-day work conference — deductible.

What doesn't count

The biggest category of non-deductible miles is commuting. Driving from your home to your regular place of business — that's commuting, and it's never deductible. Doesn't matter how long the drive is. Doesn't matter if you take work calls while driving. The IRS draws a hard line here.

Other non-deductible miles:

• Personal errands. Picking up groceries on the way home from a client meeting doesn't turn the whole trip into a business trip. Only the portion to the client meeting counts; the detour to the grocery store doesn't.
• Driving between home and a regular work location if you don't have a qualifying home office.
• Miles driven for a hobby, not a business. If your photography side hustle loses money every year, the IRS may classify it as a hobby — and hobby mileage isn't deductible.
• Miles added by taking an unnecessarily long route. If a direct route is 12 miles and you take a 20-mile scenic route, only 12 miles count. The IRS expects you to use the shortest reasonable route.

Actual expenses method

Instead of per-mile math, the actual expenses method tracks real costs: gas, oil changes, repairs, tires, insurance, registration, lease payments, and depreciation. You total everything up, then multiply by your business-use percentage.

Here's an example with a vehicle driven 20,000 total miles, of which 14,000 are business miles (70% business use):

• Gas: $3,200
• Insurance: $1,800
• Repairs & maintenance: $1,100
• Registration & fees: $400
• Depreciation: $5,000

Total: $11,500 × 70% business use = $8,050 deduction.

Compare that to the standard mileage rate for the same 14,000 business miles: 14,000 × $0.655 = $9,170. In this case, the standard method wins.

So when does the actual expenses method come out ahead? Generally when you drive a high-cost vehicle with a low business-use percentage. Gas-guzzling trucks, luxury sedans with expensive insurance, vehicles with major repair bills — these can tip the scales toward actual expenses. If you drive a modest, fuel-efficient sedan with mostly business miles, the standard rate almost always wins.

The actual method also comes with heavier recordkeeping. You need receipts for every expense, not just a mileage log. Many people start with the standard method and only switch if the numbers clearly favor actual expenses in a given year.

Depreciation limits on vehicles

If you go the actual expenses route, vehicle depreciation is one of the biggest deductions — but the IRS caps it. These are the "luxury auto limits," and they apply to any passenger vehicle, not just actual luxury cars.

For vehicles placed in service in 2026, the maximum first-year depreciation deduction is roughly $12,800 for passenger autos (assuming 100% business use and taking bonus depreciation). Without bonus depreciation, it's around $8,000. The exact numbers get adjusted annually for inflation, but the principle is: the IRS won't let you write off the full cost of a $65,000 SUV in one year just because you drive it for business.

SUV loophole: vehicles with a gross vehicle weight rating over 6,000 pounds — think Chevy Suburban, Ford Expedition, many full-size pickups — are exempt from the luxury auto limits. These qualify for full Section 179 expensing, up to $30,500 in 2026. This is why you see so many self-employed people driving large SUVs. The tax code literally incentivizes it.

For most self-employed filers with a standard sedan or crossover, the standard mileage rate is simpler and the depreciation component is already factored into the $0.655/mile rate.

Mileage tracking requirements

The IRS wants three things for every business trip: date, miles driven, and business purpose. That's it. You don't need odometer photos or GPS coordinates. But you do need a contemporaneous log — something created at or near the time of the trip. Reconstructing a year's worth of mileage the night before filing is technically fraud, and if you get audited, the IRS will throw it out.

Tracking apps like MileIQ, Everlance, and Triplog automate most of this. They run in the background, detect drives, and let you swipe to classify business vs. personal. Expect to pay $5–$15/month for a decent one. The cost of the app itself is deductible, by the way.

A manual paper log still works. A small notebook in your glovebox with columns for date, starting odometer, ending odometer, miles, and purpose — dated and kept current — satisfies the IRS just fine. The key is consistency: a log with January–March fully filled out and then "estimate" for April–December will not hold up under scrutiny.

One more thing: the IRS can ask for your total mileage for the year (business + personal). This establishes your business-use percentage, which matters for the actual expenses method and helps verify your business-mile claims. Keep a record of your odometer reading on January 1 and December 31. Most tracking apps do this automatically.

The first-year rule

This is where people make an expensive, irreversible mistake. Here's the rule:

If you use the standard mileage rate in the first year the vehicle is in service for your business, you can switch between standard and actual expenses in any later year. Standard year one, actual year two, back to standard year three — all fine.

If you use actual expenses in the first year, you're locked into actual expenses for the entire life of that vehicle. No switching back. Ever.

This matters because most vehicles depreciate fastest in their first few years. The standard mileage rate bakes in average depreciation — but your actual depreciation might be much higher in year one. Many tax preparers recommend using the standard rate for year one specifically to preserve the option to switch later, then running both calculations in subsequent years to see which method produces the bigger deduction.

One exception: if you lease the vehicle, and you used the standard mileage rate the first year, you must continue using the standard rate for the entire lease term. Leased vehicles have their own set of rules that make switching less flexible.

Mixed-use vehicles

Most people don't have a separate work-only vehicle. You drive the same car to client meetings, to the grocery store, and to your kid's soccer practice. That's a mixed-use vehicle, and it's completely normal.

The standard mileage rate handles mixed use easily: only business miles count. 15,000 total miles, 10,000 business miles. You log all 15,000 in your tracker and deduct 10,000 × $0.655 = $6,550. The personal miles are simply excluded.

With the actual expenses method, you calculate the business-use percentage: 10,000 business miles ÷ 15,000 total miles = 66.7%. Then apply that percentage to every expense category. If your annual gas bill is $3,000, you deduct $2,001. Same percentage for insurance, repairs, and depreciation.

A common scenario: you own one car used 60% for business and 40% personal. Spouse owns a separate car used 100% personal. You can't blend them — the business-use percentage applies to the business vehicle only. The spouse's car isn't part of the calculation.
