Tesla Mileage Log

Four things per trip: date, mileage, destination, and business purpose, all recorded timely (at or near the time of the trip, not reconstructed at year-end, per IRS Pub 463). VoltLogger captures the first three automatically from the car itself and lets you set the purpose in one tap.

The IRS business rate is 76 cents per mile from July 1, 2026, after a midyear increase (72.5 cents applied from January through June), and it explicitly applies to electric vehicles. At 12,000 business miles that is a $9,120 deduction, if your log holds up.

There is no IRS per-kWh rate for home charging. The safe route is an accountable plan that reimburses at or below the standard mileage rate, which is deemed to substantiate car expenses and covers operating costs including electricity. Knowing your real kWh cost is the foundation either way.

No. Your Tesla already measures its odometer, location and charging. VoltLogger reads them through the official Tesla Fleet API: connect your account once and every trip is logged from the car’s own odometer, which is what makes the log defensible.

No. VoltLogger polls adaptively: frequently while driving or charging, and it backs off when parked so the car sleeps normally. Even if a poll is missed, no miles are lost: the odometer difference reconstructs the trip and your totals always reconcile with the real odometer.

The app interface is currently Dutch; VoltLogger launched in the Netherlands first. An English version is in the works, and the logging itself (trips, odometer readings, charging sessions, CSV/PDF exports) already works with any Tesla in the US, UK or EU.

De Belastingdienst keurt geen apps of systemen goed, ook kastjes niet. Wat telt is of je registratie sluitend is: elke rit met datum, kilometerstanden, adressen en karakter. VoltLogger vult precies die officiële eisen automatisch, verankerd aan de kilometerteller van je Tesla.

Niet als fiscale administratie: de Tesla-app toont geen kilometerstanden per rit en geen zakelijk/privé-onderscheid, en exporteren kan niet. De auto méét wel alles. VoltLogger leest dat uit via de officiële Tesla-API en maakt er een sluitende rittenregistratie van.

De Tesla-app toont alleen recente laadsessies, zonder kosten tegen jouw stroomtarief en zonder export. VoltLogger bewaart élke sessie (thuis, onderweg, Supercharger) met kWh, kosten en locatie, en exporteert alles als CSV of PDF voor je administratie.

Nee. Je Tesla meet zelf al kilometerstand, locatie en laadstatus. VoltLogger leest die gegevens uit via de officiële Tesla Fleet API. Je koppelt één keer je account en er hoeft niets ingebouwd of aangesloten te worden.
