Frequently asked questions

How is the mileage tax deduction calculated?

We multiply your business miles (or kilometers) by the official standard rate for your tax authority and year — the same rates MileLog uses in IRS- and CRA-compliant PDF reports. Tiered schedules (like Canada's first 5,000 km) are applied automatically.

What marginal tax rate should I use?

Use the tax bracket rate on your last dollar of income — your accountant can confirm this. If you're unsure, 22% is a reasonable US federal starting point for many self-employed filers; add state/provincial tax if applicable.

Is this tax advice?

No. This calculator is for estimation only. Tax situations vary. Consult a qualified tax professional before filing.

What counts as business mileage?

Generally, driving between work locations, to meet clients, or for other business purposes — not commuting from home to a regular workplace. Rules differ by country; MileLog helps you categorize and document trips for your records.
