1099 Tax Calculator for Self-Employed Workers

Smart Miles is designed for all-day use. It uses motion detection to activate GPS only when you're driving, and switches to low-power heartbeat mode when stationary. Most users see minimal battery impact — comparable to having Google Maps installed.

Yes. Smart Miles captures every field needed for mileage deductions: date, destination, business purpose, and miles driven. Records are created contemporaneously (at the time of travel), which is what the IRS recommends for substantiation. Export a CSV with all fields for your accountant or tax software.

Absolutely. Tap the + button to manually add a trip with start/end locations, date, time, and purpose. The app calculates the driving distance automatically.

Smart Miles offers three tiers of auto-classification (frequent trip rules, work hours, and manual), accurate road-level routes, and a full web dashboard — all included. We never delete your unclassified trips, and we don't gate exports behind a premium plan.

Smart Miles includes the official IRS Standard Mileage Rates, updated whenever the IRS changes them. For 2026 (as of July 1): Business at $0.76/mile, Medical/Moving at $0.235/mile, and Charity at $0.14/mile. You can also set custom rates if your employer reimburses at a different amount.

Yes. Every Smart Miles account includes a web dashboard where you can view, edit, filter, and export your trips from any browser. Same data, bigger screen.

A W-2 means you're an employee — your employer withholds taxes and pays half of Social Security and Medicare for you. A 1099 means you're an independent contractor: you're considered self-employed, taxes aren't withheld, and you pay both halves of Social Security and Medicare yourself.

No. The IRS expects self-employed taxpayers to pay estimated taxes quarterly. The calculator divides your estimated annual tax by four to give you a rough per-quarter figure. Paying quarterly helps you avoid an underpayment penalty at filing time.

Common deductions include business mileage (usually the largest), a home office, phone and internet used for work, supplies, and professional services. For driving, the standard mileage rate of 76¢/mile in 2026 already bundles gas, maintenance, insurance, and depreciation — so you can't deduct those separately if you use the mileage method.

It's a planning estimate using 2026 federal and state tax figures. It doesn't capture every credit, deduction, or local tax, and it isn't tax advice. Use it to ballpark what you'll owe and how much your mileage deduction is worth — then confirm with a tax professional before filing.
