If you drive for work, every untracked mile is money left on the table. The IRS standard mileage rate for 2026 sits at 70 cents per mile. Drive 10,000 business miles in a year and you're looking at a $7,000 deduction. Miss those miles because you forgot to log them, and you pay taxes on income you spent on gas, wear, and maintenance.
Tracking mileage sounds straightforward. In practice, most freelancers and self-employed people start strong in January and stop logging by March. This guide covers what counts as business mileage, which tracking method to use, what records to keep, and how to build a system you'll stick with all year.
What Counts as Business Mileage
The IRS considers vehicle costs an ordinary and necessary business expense. But not every trip in your car qualifies. You need to know the difference before you start tracking.
Trips between two work locations count. Driving from your home to a temporary work site counts. Client visits, business errands, and trips to the bank or post office for business purposes all count. Similar rules apply in the UK under HMRC, in Australia under the ATO, in Canada under the CRA, and in New Zealand under the IRD.
Your daily commute from home to a permanent workplace does not count. Carrying tools in your car during a personal commute does not make it a business trip. Displaying a business logo on your vehicle does not convert personal miles into business miles.
- Driving between two different work locations
- Traveling from home to a temporary job site
- Visiting clients or attending business meetings
- Running errands for your business, like picking up supplies
- Driving to the bank or post office for business tasks
Standard Mileage Rate vs. Actual Expenses
You have two options when claiming vehicle expenses on your tax return. The first is the standard mileage rate. You multiply your total business miles by the government-set rate. For 2026 in the US, the IRS rate is 70 cents per mile. Australia, the UK, Canada, and New Zealand each publish their own rates.
The second option is the actual expenses method. You add up everything you spent on gas, insurance, repairs, depreciation, registration, and lease payments. Then you multiply the total by the percentage of miles driven for business. If 60% of your driving was for work, you deduct 60% of those costs.
The standard mileage method is simpler. You track miles and multiply. The actual expenses method requires you to keep every receipt and calculate your business-use percentage. For most freelancers, the standard rate saves more time and often produces a comparable or larger deduction. Run the numbers both ways in your first year to see which works better for your situation.
What Your Mileage Log Needs to Include
Tax authorities want specific details. A vague note saying "drove for work" will not survive an audit. Each trip entry in your log should include the following.
- Date of the trip
- Starting location and destination
- Business purpose of the trip
- Odometer reading at the start and end, or total miles driven
- Name of the client or project, if applicable
Record your odometer reading on January 1 and again on December 31 each year. This gives you total annual miles. Combined with your logged business miles, it shows the IRS or your local tax authority a clear split between personal and business use.
Keep your records for at least three years after filing your return. The IRS and most other tax agencies require this retention period. Store digital copies in case paper logs get lost.
Three Ways to Track Your Miles
Paper logbook
A notebook in your glove box works. Write down each trip as it happens. The problem is consistency. Paper logs are easy to forget, hard to total up at year end, and simple to lose. If you drive fewer than a dozen business trips per month, a paper log is manageable. Beyond that, it becomes a chore.
Spreadsheet
A spreadsheet gives you automatic totals and a searchable record. You enter trip details at the end of each day or week. It is more reliable than paper but still depends on you remembering to log every trip. One busy week without entries and you start estimating, which weakens your records.
Mileage tracking app
A dedicated tracking tool removes the friction. The best apps let you log trips quickly with preset business purposes, built-in tax rates for your country, and running totals of your deduction. You spend 10 seconds per trip instead of 2 minutes. TrackrAI includes mileage tracking with current ATO, IRS, HMRC, CRA, and IRD tax rates built in, so your deduction calculates automatically as you log each trip.
Habits That Keep Your Log Accurate All Year
The tracking method matters less than the habit behind it. People who fail at mileage tracking almost always fail because they try to log trips at the end of the week or month. By then, details blur together.
- Log every trip immediately, before you leave the car
- Set a daily reminder on your phone at the time you usually finish driving
- Review your log once a week to catch missing entries while your memory is fresh
- Take a photo of your odometer on the first and last day of the tax year
- Link mileage tracking to your expense tracking so everything lives in one place
If you already track expenses and time for your freelance work, adding mileage to the same system reduces the number of apps and habits you need to maintain. One place for all your financial records makes tax season faster and less stressful.
Common Mistakes to Avoid
Rounding up miles is tempting but risky. If the IRS checks your log against GPS data or client records and the numbers don't match, your entire mileage claim gets questioned. Log exact miles.
Claiming commuting miles is the most common error. Your regular drive from home to your main office is personal, even if you are self-employed and your office is a coworking space you rent. Trips from your home office to a client site, on the other hand, do qualify.
Reconstructing a log at year end is another red flag. Tax authorities expect contemporaneous records, meaning records made at or near the time of the trip. A log created in bulk the night before filing looks exactly like what it is.
TrackrAI lets you track mileage alongside your expenses, timesheets, and financial reports in one app. With built-in tax rates for the IRS, ATO, HMRC, CRA, and IRD, your deduction updates automatically every time you log a trip. No spreadsheets, no guesswork, no scrambling at tax time.
