Short answer

Both methods price the same business miles, so the decision is which figure is larger and which one you can document. For 2026 the standard mileage rate is 72.5 cents per mile from January 1 to June 30 and 76 cents per mile from July 1, and it already covers fuel, oil, repairs, tires, insurance, registration and depreciation. The actual expense method deducts your own costs multiplied by the share of the year's miles that were for business. The standard rate pays more for most drivers of ordinary cars; actual expenses can pay more when the car is expensive to run relative to how much of its driving is business. The decision that is hard to undo is the first-year election, not this year's total.

At a glance

  • 2026 business rate: 72.5 cents per mile January 1–June 30 and 76 cents per mile from July 1. Each trip uses the rate in force on the day it was driven.
  • The standard rate bundles fuel, oil, maintenance, tires, insurance, registration and depreciation. Business parking fees and tolls are deductible on top of it.
  • Actual expenses use one ratio for everything: business miles ÷ total miles for the year, applied to every eligible cost.
  • First-year election: for a car you own, choose the standard rate in the first year it is available for business use, or the standard rate is off the table for that car later.
  • A leased car stays on whichever method you start with for the entire lease period, renewals included.
  • The standard rate is unavailable if you claimed MACRS, a Section 179 deduction or the special depreciation allowance on the car, or if you use five or more cars at the same time.

Where each side fits

When the standard rate wins

Standard mileage
  • Your cost per mile driven is average or below, so the published rate is the better price for the miles.
  • You want one number per trip and no receipt file: a log with date, destination, purpose and miles is the whole record.
  • You drive a lot of business miles, because the rate pays per mile while most car costs do not rise with them.
  • You are not ready to commit: starting with the standard rate keeps the option to switch to actual expenses later.

When actual expenses win

Actual expenses
  • The car costs a lot to run — fuel, insurance, repairs or depreciation — relative to the share of its miles that are business.
  • A large repair, or a lease or loan year, lands in the same year as a lot of business driving.
  • You already keep every receipt and the lease or loan paperwork, and you want the deduction to follow real costs.
  • You claimed, or have to claim, depreciation separately — for example because a Section 179 or bonus depreciation election was made.

The two methods, side by side

The same miles, priced two ways. Everything below is what the two methods differ on once the mileage log itself is in place.

The 2026 rate, and why the year has two of them

The IRS published the 2026 business rate at 72.5 cents per mile in Notice 2026-10. Rising fuel prices then pushed it to 76 cents per mile from July 1 under Announcement 2026-11, which modified the earlier notice rather than replacing it. Both figures are still 2026 rates, and the date the miles were driven decides which one applies.

6,000 business miles in each half of the year therefore price out at $4,350.00 plus $4,560.00, or $8,910.00. Applying the later rate to the whole year would give $9,120.00 and overstate the claim by $210.00.

  • A trip that crosses June 30 splits at the date boundary rather than taking one rate for the whole journey.
  • Medical and moving mileage moved with the business rate: the second-half figure is higher than the first-half one.
  • The charitable rate is the exception. It stays at 14 cents per mile because the Code sets it, not the IRS cost study.

How the actual expense method is figured

One ratio carries the whole method. Add the year's total miles and business miles, divide the business figure by the total, and apply that share to every eligible cost. The costs that count are fuel and oil, repairs and maintenance, tires, insurance, registration and licence fees, lease payments, the business part of loan interest, and depreciation or a Section 179 election.

Take a car driven 20,000 miles in the year, 12,000 of them for business, with $14,000.00 of running costs. The business share is 60%, so actual expenses give $8,400.00. The same 12,000 business miles at the second-half rate give $9,120.00: a cost of 70¢ per mile driven is cheap enough that the standard rate wins by $720.00.

That comparison is the whole decision, and it is worth re-running each year. A repair year, a lease that has ended or a change in how much you drive can flip it without the car changing at all.

  • Personal miles are never deductible, so the business-use share is what keeps the claim honest.
  • Commuting between home and a regular workplace is personal mileage, even though it is driving you do for work.
  • If you claim actual expenses, keep the receipts for the costs you count. The mileage log is still required, because the business-use share comes from it.

The break-even test you can run on your own numbers

Actual expenses only pay more than the standard rate when your cost per mile driven is high enough to beat the rate divided by your business-use share. Dividing matters: at a 60% business-use share, three-fifths of every cost is deductible, so the car has to be significantly more expensive per mile than the rate itself before the actual method pulls ahead.

The table below is that line for 2026, at each business-use share. Find your share, compare it with your own cost per mile driven, and the method with the larger figure wins.

Business-use shareCost per mile driven that beats the 76 cents per mile rate (Jul–Dec)Cost per mile driven that beats the 72.5 cents per mile rate (Jan–Jun)
100%76¢72.5¢
80%95¢90.6¢
70%108.6¢103.6¢
60%126.7¢120.8¢
50%152¢145¢
40%190¢181.2¢

Cost per mile driven is total vehicle costs for the year divided by total miles driven. Above the line, actual expenses pay more than the standard rate.

The first-year rule, and what switching costs

For a car you own, the standard rate has to be chosen in the first year the car is available for business use. Choose it, and later years can use either method. Start with actual expenses instead, and the standard rate is no longer available for that car. The IRS asks for the choice by the due date of the return, including extensions, and it cannot be revoked.

Switching from the standard rate to actual expenses in a later year is allowed, but the depreciation changes: you estimate the car's remaining useful life and use straight-line depreciation, with the basis reduced by the depreciation already included in the miles you claimed at the standard rate. That basis adjustment is why switching is not a free option.

A leased car follows a different rule. If you use the standard rate for it, you keep using the standard rate for the entire lease period, renewals included, and you cannot move that car onto actual expenses.

When the standard rate is not available

The rate is optional, and the IRS lists the cases where the option is gone. Each one is about depreciation or scale rather than about the driver's preference.

  • Five or more cars are used for business at the same time, as in a fleet operation. Alternating between cars does not count as using them at the same time.
  • Depreciation was claimed on the car using a method other than straight line for its estimated useful life.
  • The car was depreciated under MACRS, or a Section 179 deduction or the special depreciation allowance was claimed on it.
  • Actual expenses were claimed on a car you lease, after 1997.
  • The car was provided by an employer: unreimbursed actual costs can be deductible in the narrow cases below, but the standard rate cannot be used.

Records both methods need — and where the $75 figure comes from

The log is the record that decides whether either method survives a review, and the IRS asks for it to be made at or near the time of the trip rather than reconstructed at filing. Approximated or estimated amounts cannot be deducted.

  • Date, destination, business purpose and mileage for each business trip.
  • Total miles for the year as well as business miles, because actual expenses need the ratio and the ratio is easier to defend when the odometer record is complete.
  • Receipts, invoices and the lease or loan agreement for every cost claimed under the actual method.
  • The $75 figure is a documentation threshold for travel expenses, not a mileage rule: receipts are required for each expense of $75 or more other than lodging, and for lodging at any amount. It never substitutes for the mileage log.

Employees, employers, and the rate as a reimbursement benchmark

For a W-2 employee, the two methods in this comparison are rarely a personal deduction at all. Unreimbursed employee expenses have not been deductible since 2018, and the suspension was made permanent, so the route for an employee is the employer's reimbursement policy rather than a return.

The exception list is narrow: a member of the Armed Forces or a military reservist, a qualified performing artist, and a fee-basis state or local government official. Everyone else deducts nothing for unreimbursed business driving.

For the self-employed, the same rates become a Schedule C deduction, and it reduces income tax and the self-employment tax that applies to net profit. Employers using an accountable plan can reimburse at the standard rate without the payment becoming taxable income, provided the plan requires the date, destination, business purpose and miles, and any excess advance is returned.

Choosing on the numbers you have

Work through these in order; each one is a figure you already have or can get from your own records.

  • Write down the year's total miles and business miles. Both methods need the log; only actual expenses need the ratio.
  • Add up fuel, oil, repairs, tires, insurance, registration, lease or loan payments, and any depreciation you claimed.
  • Divide total costs by total miles. That is your cost per mile driven.
  • Compare it with the break-even line for your business-use share in the table above.
  • Check the lock-ins before choosing: the first year for a car you own, the whole lease period for a leased car, and any depreciation already claimed.
  • If you are still unsure, start with the standard rate. It preserves the option to move to actual expenses in a later year.

Common questions

Can I switch between standard mileage and actual expenses each year?

Only in one direction for a car you own. If you used the standard rate in the first year the car was available for business use, later years can use either method, and moving to actual expenses means straight-line depreciation with a basis adjustment for the depreciation already inside the miles you claimed. If you started with actual expenses, the standard rate stays unavailable for that car. A leased car keeps the method you started with for the whole lease period.

What is the $75 rule in the IRS?

It is a receipts threshold, not a mileage rule. For business travel you need documentary evidence for each expense of $75 or more other than lodging, and for lodging at any amount. It does not let you claim mileage or vehicle costs without records, and it does not raise the standard mileage rate.

Can you deduct both mileage and car expenses?

Not for the same miles. The standard rate stands in for fuel, oil, repairs, tires, insurance, registration and depreciation, so those costs cannot be deducted on top of it. Business parking fees and tolls are the exception and are deductible alongside either method. The business part of state and local personal property taxes, and vehicle loan interest, follow their own rules rather than the rate.

Does the standard mileage rate cover a big repair?

The repair is inside the rate, so it cannot be deducted separately. A year with an expensive repair is exactly when the actual expense method can beat the standard rate, which is why it is worth pricing both methods for that year rather than assuming the rate always wins.

Which method pays more for a high-mileage driver?

High business mileage usually favours the standard rate, because the rate pays for every mile while most car costs do not rise with mileage. Actual expenses tend to win on cars that are expensive per mile driven, or where the business-use share is high and the operating costs are well documented.

Does the standard mileage rate apply to a leased car?

Yes, at the same rate, but with a lock-in. Choose the standard rate for a leased car and you must use it for the entire lease period, renewals included, and the car cannot move to actual expenses later.

Can I deduct unreimbursed mileage as an employee?

No, with a short list of exceptions. Unreimbursed employee expenses have not been deductible since 2018 and the suspension was made permanent, so a W-2 employee's route is the employer's reimbursement policy. The exceptions are members of the Armed Forces and military reservists, qualified performing artists, and fee-basis state or local government officials.

Do I have to use two rates for 2026?

Yes. Each trip uses the rate in force on the day it was driven: 72.5 cents per mile before July 1 and 76 cents per mile from July 1. Price the two halves of the year separately rather than applying the later rate to all of it, and split a trip that crosses June 30 at the date boundary.
