Enter the miles you drove and the rate per mile to see your mileage tax deduction or reimbursement. Pre-filled with the current IRS standard mileage rates, and fully editable. Free, and no signup needed.

It is a free tool that works out your mileage deduction or reimbursement in seconds. Enter the miles you drove for a purpose, pick a rate (it comes pre-filled with the current IRS standard mileage rate), and it multiplies the two for you. Freelancers and small businesses use it to estimate the tax deduction on business driving, and to check a mileage reimbursement before they invoice a client or pay an employee.
The IRS sets a standard rate per mile each year, and for 2026 it raised the business rate mid-year because of fuel prices. These are the current rates:
| Purpose | Rate per mile |
|---|---|
| Business (from July 1, 2026) | 76 cents |
| Business (Jan 1 to June 30, 2026) | 72.5 cents |
| Medical | 23.5 cents (20.5 cents before July 1) |
| Moving, active-duty armed forces | 23.5 cents (20.5 cents before July 1) |
| Charitable (set by law) | 14 cents |
Rates from the IRS Standard Mileage Rates page. The business rate rose to 76 cents per mile effective July 1, 2026. Always confirm the current figure at irs.gov before you file, since the IRS can revise it. This tool is for estimates and general information, not tax advice.
The standard mileage method is simple: multiply your business miles by the rate per mile. So 10,000 business miles at 76 cents a mile is a 7,600 dollar deduction (10,000 times 0.76). Keep a mileage log with the date, purpose, and miles for each trip, because the IRS expects a record if you are ever asked to back up the number. For a deeper look at what qualifies and how to keep a log, see our guide on how to track and deduct business mileage.
There are two ways to deduct car costs for business. The standard mileage rate (what this calculator uses) applies one flat rate per mile and is the simplest to track. The actual expense method adds up your real costs, gas, insurance, repairs, depreciation, and more, then deducts the business-use share. Most people who want an easy, defensible number use the standard mileage rate. If you drive an expensive vehicle or have high running costs, the actual expense method can sometimes give a bigger deduction, so it is worth comparing.
Business miles are trips for work, such as driving to a client, a job site, the bank, or to buy supplies. Your normal commute from home to a regular workplace does not count. Medical and charitable miles have their own lower rates and their own rules, and moving miles only apply to active-duty military moving on orders. When in doubt, keep the trip in your log with a note on its purpose and confirm the treatment with a tax professional.
Whatever the trip is for, the habit is the same: log it as you go. A quick note per trip, date, where, why, and miles, is all the IRS asks for, and it makes tax time painless. If the driving is reimbursable by a client, add it as a line item so it lands on the invoice. When the job is done, our free invoice generator turns those line items into a professional invoice you can send in minutes.
Log expenses, attach receipts, add reimbursable costs to an invoice, and see what each client and project really costs, all from one Billbooks account.
