Finnish Mileage & Per Diem

Log business trips and claim Finnish per diem — domestic päiväraha and the country-by-country ulkomaanpäiväraha — plus the tax-free kilometre allowance (kilometrikorvaus), at Verohallinto's rates.

Someone logs the trip and the tax-free allowance is worked out at the official rates for Finland, 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.
