Calculate your IRS business mileage deduction at $0.70/mile for 2026. Compare standard vs. actual expense method and see total tax savings including SE tax.
The 2026 IRS standard mileage rates are: Business $0.70/mile · Medical/Moving $0.21/mile · Charitable $0.14/mile. The business rate is used on Schedule C (self-employed) or Schedule F (farming). W-2 employees cannot deduct unreimbursed business mileage on federal taxes (suspended through 2025 by TCJA). The IRS requires a contemporaneous mileage log — use apps like MileIQ or Everlance to automate tracking.
The IRS standard mileage rate is designed to cover the full cost of business vehicle use in one simple per-mile rate. The rate is calculated annually by the IRS to reflect the cost of owning and operating a vehicle — including fuel, depreciation, insurance, maintenance, and registration. By multiplying business miles by the standard rate ($0.70 in 2026), you arrive at your total vehicle expense deduction without needing to track individual costs.
The key distinction is what qualifies as business mileage. Driving between your home and a regular workplace is commuting and is never deductible. Business mileage includes driving between job sites or clients, driving to a temporary work location, business errands and supply runs, travel to meetings, and travel to a secondary work location if you have a qualified home office. If you use a personal vehicle for both business and personal trips, only the business percentage is deductible.
For self-employed individuals, the mileage deduction reduces Schedule C net income, which reduces both federal income tax AND self-employment tax (15.3%). This double tax benefit makes the mileage deduction one of the most valuable deductions available to freelancers, Uber/Lyft drivers, gig workers, and small business owners who drive for business.
Olivia is a self-employed real estate agent in Arizona earning $75,000 net, single filer, who drives 10,000 business miles per year. She also has $8,000 in total vehicle expenses with 60% business use.
Olivia's $7,000 standard mileage deduction generates $2,703 in combined tax savings — that's a 38.6% effective tax benefit on her mileage deduction. The standard method outperforms actual expenses by $2,200 in deduction, adding approximately $848 in additional tax savings she would have missed using actual expenses.
Standard vs. actual method decision
Choose between standard and actual based on your vehicle's costs. Fuel-efficient vehicles typically fare better under the standard method since the IRS rate assumes average fuel costs. Older, expensive-to-operate vehicles with high maintenance and insurance costs may benefit from the actual method. You must use the standard mileage method in the first year a vehicle is used for business to retain the option to switch to actual later. You cannot switch from actual to standard after the first year.
Contemporaneous records are required
The IRS's record-keeping requirements for mileage are strict. You need the date, destination, business purpose, and miles for each trip, recorded at or near the time of the trip. Apps like MileIQ, Everlance, and TripLog automatically capture this data using GPS and allow you to swipe left (personal) or right (business) to categorize trips in seconds. At audit, a well-organized digital log is significantly more defensible than a handwritten log created months after the fact.
Multiple vehicles and mixed use
If you use multiple vehicles for business, you can track and deduct mileage on each vehicle separately. For vehicles used for both personal and business trips, only business miles are deductible. Track total annual miles for each vehicle — the IRS requires you to show the business use percentage. A vehicle used 100% for business can deduct its full mileage. A vehicle used 40% for business deducts 40% of either actual expenses or the standard rate mileage for business trips.

The IRS standard mileage rate for business driving in 2026 is $0.70 per mile ($70 cents per mile). This rate covers the full cost of operating a vehicle for business — gas, depreciation, insurance, and maintenance — so you cannot deduct actual vehicle expenses separately if you use the standard mileage rate. The 2026 medical and moving mileage rate is $0.21 per mile, and the charitable mileage rate is $0.14 per mile (the charitable rate is set by Congress and does not change as frequently as the other rates).
Self-employed individuals, business owners, and independent contractors can deduct business mileage on Schedule C or Schedule F (farming). Employees who use their personal vehicle for work purposes cannot deduct unreimbursed mileage on federal taxes — this deduction was suspended by the 2017 Tax Cuts and Jobs Act for tax years 2018 through at least 2025. If you are a W-2 employee with significant unreimbursed mileage, request reimbursement from your employer under an accountable plan rather than trying to deduct it. Some states still allow employee mileage deductions — check your state tax rules.
The standard mileage method multiplies business miles driven by the IRS rate ($0.70/mile in 2026) and deducts the result. It is simple but may understate or overstate your actual costs. The actual expense method tracks all vehicle costs — gas, oil, tires, insurance, registration, lease payments, and depreciation — then multiplies by the business use percentage. If actual costs × business% exceed the standard rate deduction, the actual method produces a larger deduction. You must choose your method in the first year you use the vehicle for business, and switching from actual to standard is restricted.
The IRS requires a contemporaneous mileage log documenting: the date of each trip, the destination (city or name of place), the business purpose, and the miles driven. "Contemporaneous" means recorded at or near the time of the trip — reconstructed logs created later are less likely to survive an audit. Apps like MileIQ, Everlance, TripLog, and Hurdlr automatically track mileage using your phone's GPS and categorize trips as business or personal. Without a mileage log, the IRS can disallow your entire mileage deduction, even if the trips were genuinely business-related.
Yes. For self-employed individuals, the mileage deduction reduces net self-employment income on Schedule C. This reduction flows through to lower SE tax (15.3%) as well as lower federal and state income tax. For example, a $7,000 mileage deduction at the 15.3% SE tax rate saves $1,071 in SE tax alone, plus $1,540 in federal income tax at the 22% bracket, for a total savings of $2,611. This dual tax benefit makes mileage deductions particularly valuable for freelancers and small business owners compared to W-2 employees.
