Estonian Mileage & Per Diem

Keep the personal car logbook (soidupaevik) and record foreign assignments, within the tax-free ceilings of tulumaksuseadus 13 lg 3 and the daily allowance minimum of maarus nr 110. Estonia has no domestic daily allowance, and the app explains why.

Someone logs the trip and the tax-free allowance is worked out at the official rates for Estonia, then lands in the ledger already coded. No claim spreadsheet, and no rate table for a finance person to remember to update when the authorities move them.
