Mileage Tracker for Taxes: What Records You Need and How to Keep Them
A mileage tracker for taxes only helps if your log has the fields tax authorities care about. Here is what to record for US and Canadian business driving, how to build the habit all year, and how MileLog fits—without guessing at year end.
Mileage Tracker for Taxes: What Records You Need and How to Keep Them
MileLog is currently available for iPhone and iPad through the App Store. These tips are for drivers who track work trips with an iOS device.
Direct answer: If you drive for work as a self-employed person, contractor, realtor, or gig driver, you need a contemporaneous log of business travel—not a year-end guess. A useful tax mileage log usually includes the date, distance, business purpose, and enough route context (start/end or destination) to show the trip was real. In the US, many people use the IRS standard mileage rate or actual expenses, but both still need clear records. In Canada, CRA commonly expects business kilometres as a share of total kilometres plus trip detail (and odometer context for the period). A mileage tracker helps only if it captures those fields while you drive and can export something you or your bookkeeper can actually use.
This is not tax advice; actual savings depend on your driving, records, and local rules. MileLog organizes mileage records—it does not file your return or decide what is deductible.
What a tax mileage log should include
Treat this as a practical checklist. Your accountant or local rules may ask for more.
| Field | Why it matters |
|---|---|
| Date | Shows the trip happened in the tax period |
| Distance (miles or km) | Basis for rate methods or business-use % |
| Business purpose | Separates work from personal driving |
| Start / end or destination | Supports that the trip was real and work-related |
| Business vs personal | Prevents mixing categories in one total |
| Notes (optional) | Client, job, platform, or showing ID when useful |
| Period odometer (especially CA) | Helps support total km vs business km for the year |
Rebuild-from-memory logs fail for two reasons: you under-count real work miles, or you cannot explain the ones you claimed. The log that protects a deduction is the one built while the trip is still fresh.
US and Canada: same habit, different framing
Rules change by year and situation. Use official pages for current rates and eligibility—do not treat any blog number as permanent law.
United States (high level)
- The IRS publishes standard mileage rates and explains when the standard-rate method may apply: IRS standard mileage rates.
- Broader travel and recordkeeping context lives in IRS materials such as Publication 463 (Travel, Gift, and Car Expenses). Check the current edition for examples of what a daily log can look like.
- Many self-employed drivers choose between standard mileage rate and actual expenses. The choice and eligibility depend on your facts; a clean mile log still matters either way.
- Do not hardcode a cents-per-mile figure from memory into your process. Look up the rate for the tax year you are filing.
Canada (high level)
- CRA motor vehicle guidance for businesses explains recording total kilometres and kilometres driven to earn business income, and listing trip date, destination, purpose, and kilometres, plus odometer readings for the fiscal period: CRA motor vehicle expenses.
- A common mental model is: business-use percent = business km ÷ total km, then apply that percent to eligible vehicle costs. Eligible costs and limits depend on your situation.
- Kilometre logs without receipts (or receipts without kilometres) are incomplete for many claims.
Shared truth for both countries
- Contemporaneous beats reconstructed.
- Business purpose is not optional decoration.
- Exports should match what your bookkeeper asked for (period, columns, totals).
- App marketing language is not a substitute for official rules.

A year-round routine that actually sticks
Tax season is a reporting problem. The hard part is the 50 weeks before it.
- Capture trips automatically while you work (background tracking on your phone).
- Classify business vs personal the same day or end of shift—while you still know why you drove.
- Add a short purpose when the trip is not obvious from the address (client name, job site, platform block, open house).
- Export monthly or quarterly and store the file with your tax folder—not only in the app.
- Review odd trips before they pile up (personal runs mis-tagged as work, missing chunks of a multi-stop day).
If you only open a mileage app in March, you will rebuild history under stress. If you spend two minutes after a shift, tax time is mostly export and review.
What to hand a bookkeeper or tax preparer
Ask them what they want. A strong package often includes:
- Date range for the tax year or fiscal period
- Business miles/km total and personal total (or clear filters)
- Trip-level detail: date, distance, purpose, locations
- Any odometer period summary they request (especially Canada)
- Related vehicle cost receipts if you use actual expenses / cost methods
- A short note on how you track (app + review habit), if they ask for process
MileLog is built to make that package less painful: automatic mileage capture, business/personal review, purposes, and exportable reports so you are not pasting screenshots into a spreadsheet the night before a deadline.
How MileLog helps (and what it does not do)
Helps with:
- Automatic mileage tracking on iPhone and iPad so work trips are less likely to disappear
- Quick business vs personal classification
- Purposes and history you can review before export
- Reports you can share with yourself or a preparer
- A lighter daily habit than a paper logbook after a long shift
Does not do:
- Decide whether a trip is legally deductible
- Replace a CPA, EA, or tax lawyer
- Guarantee savings, refund size, or audit outcome
- Make “CRA-compliant” or “IRS-compliant” a magic stamp—authorities care about your facts and records, not a product slogan
For drivers who also care about whether miles are worth the payout, see the real profit mileage guide. For multi-app days where trips blur together, see the multi-app gig driver guide.
Limits and non-claims
- This page is educational product guidance, not tax, legal, or accounting advice.
- Deductibility, rates, and methods depend on jurisdiction, entity type, and tax year.
- Automatic tracking can miss trips if permissions, battery settings, or device state block location—review your log; do not assume perfection.
- “Audit-ready” in marketing means organized, detailed, exportable records. It does not mean “immune to questions” or “pre-approved by a tax agency.”
