Kørselsfradrag
In development
An iOS app that keeps track of your commutes and works out the Danish mileage deduction (befordringsfradrag) under § 9 C of the Danish Tax Assessment Act. Everything stays on your own phone.
What the app does
Log one leg at a time — the outbound trip and the return are separate entries.
Two starting points: your usual residence and a summer house. Trips from the summer house still count, but are capped at what the day would have given from the usual residence.
Distances are calculated as a driving route between the addresses you enter, not as the crow flies. When routing fails, the app says so plainly rather than pretending otherwise.
Ferry costs, with a photo of the receipt.
Øresund crossings, at the fixed statutory amount per crossing.
CarPlay: log a trip with a single tap from the car. Trips logged this way are flagged so you can add the receipt and amount afterwards.
A yearly summary with the total deduction and an estimate of its tax value, exportable as CSV.
How the deduction is calculated
The deduction is banded on the whole day's round trip, not on each leg on its own. So the app adds up the day's legs before spreading the kilometres across the rates:
The first 24 km of the day yield nothing.
25–120 km are deducted at the full rate.
Above 120 km the rate drops — unless your usual residence is in an outlying municipality (yderkommune), where the full rate continues all the way up. Bornholm is one such municipality.
Status
The app is in development and is not on the App Store yet. CarPlay support additionally depends on Apple granting the required entitlement, which cannot be enabled without their approval.
A caveat
The app is a calculator, not tax advice. Rates and thresholds change from year to year, and the figures the app uses should be checked against SKAT's own page on befordringsfradrag before you put any result on your tax return. What you file remains your responsibility.
Privacy
The app does not send your trips, addresses or receipts anywhere. There is no account, no analytics and no third parties. The privacy policy spells it out.
