Frequently asked questions

It securely connects to your Tesla account and reads your trips automatically, without a dongle or manual entry.

Odoproof keeps contemporaneous records with date, postcodes, distance and purpose, and a running business-use percentage: the kind of substantiation HMRC expects for Benefit-in-Kind, Self Assessment and VAT. It is not tax advice; your accountant remains your source of truth.

Tracking begins once you connect your Tesla; trips are captured going forward. There is no reliable way to reconstruct journeys you didn't record.

Yes. A pure-electric Tesla has no Car Fuel Benefit Charge (electricity isn't a 'fuel'). Clean journey and charging records let you reclaim business charging at HMRC's Advisory Electricity Rate and keep your Benefit-in-Kind reporting right.

We use least-privilege access to your Tesla data, encrypt it, and never sell it. See our Security page.

Odoproof costs $9/mo for up to 3 vehicles or $49/mo for up to 30. For more vehicles, ask for a Custom plan at contact@odoproof.com.

Yes. Every paid plan includes a 7-day free trial that starts when you subscribe, with immediate access to the app. Cancel anytime during the trial at no charge.

No. HMRC does not treat electricity as a 'fuel', so the Car Fuel Benefit Charge does not apply to a pure-electric company car such as a Tesla. This differs from petrol, diesel and plug-in hybrid cars.

The appropriate percentage for a pure-electric company car is 4% for 2026/27. It rises to 5% in 2027/28, 7% in 2028/29 and 9% in 2029/30. The taxable benefit is the list price times this percentage, and you pay income tax on it at your marginal rate.

From 1 September 2026, HMRC's Advisory Electricity Rate is 7p per mile for home charging and 15p per mile for public charging, unchanged since 1 March 2026 (7p and 14p applied from 1 December 2025). These rates are reviewed quarterly, so check the current figure before each claim.

No. Benefit-in-kind is based on list price and the appropriate percentage, and the number of business miles you drive does not change it. The mileage log supports business-mileage reimbursement, VAT recovery and self-employed cost apportionment.

Each business journey should show the date, start and end locations including postcodes, the purpose of the trip and the distance travelled. Commuting to a regular workplace must be logged as private, and HMRC accepts electronic and telematics records.
