A mileage tracker app that doesn't live alone
Log a trip, and FinnLion turns it into a deduction using the standard IRS rate — right next to the budgets, invoices, and tax estimate it's already feeding.

Date, purpose, and miles — that's it. No odometer photos, no separate account to manage.
Automatic IRS-rate math
Every logged mile multiplies by the current standard rate — update the rate once when the IRS changes it, and every trip recalculates.
Tagged business or personal
A side hustle's miles never get mixed in with your day job's, or your personal errands.
Flows into your tax estimate
Mileage deductions aren't stuck in a standalone log — they're part of the same numbers behind your quarterly tax estimate.
Why not just use a dedicated mileage app?
A standalone mileage tracker gives you a deduction number that still has to be copied somewhere else to matter — into a spreadsheet, into your accountant's intake form, into a separate budgeting app. FinnLion logs the trip once and uses it everywhere: in your quarterly tax estimate, in your budget's business spending, and in your year-end numbers. One less app, one less number to reconcile by hand.
Frequently asked questions
What mileage rate does FinnLion use?▼
The standard IRS business mileage rate, which you can update any time a new rate takes effect. FinnLion multiplies your logged miles by that rate to calculate the deduction automatically.
Do I need a separate app just for mileage?▼
No — mileage tracking is built into FinnLion alongside your budgets, invoices, bank sync, and quarterly tax estimate, so your deduction feeds straight into your real financial picture instead of sitting in an app you check separately.
Can I track mileage for more than one business or side hustle?▼
Yes. Each trip is tagged business or personal and can be linked to a category, so mileage from a side hustle stays separate from your main business or day job.
Mileage is one piece. FinnLion is the whole picture.
Invoicing, budgeting, bank sync, debt payoff, and quarterly taxes — built for freelancers and side hustles, not an enterprise team you don't have.
