Travel Expense Calculator
German per diems and mileage
Calculates business-trip allowances under German tax rules and turns them into a report for your records or your employer. Domestic per diems follow § 9 (4a) EStG: the partial rate for more than 8 hours away and for arrival and departure days, the full rate for days with 24 hours away, and the rule for trips over midnight without an overnight stay. Trips abroad use the country and city rates of the BMF table in force on the travel date, the place reached before midnight and the last place of business abroad, and the BMF fallback rules for countries the table does not list. Meals provided by the employer reduce the per diem, never below zero. Mileage uses the statutory per-kilometre rates for cars and other motor vehicles; the overnight flat rate is applied only for employer reimbursement. Receipts you enter are added at actual cost. You get an itemised breakdown in chat, a PDF report and a CSV for payroll or bookkeeping, and every result names its source and valid-from date. Not covered: public-sector travel law (BRKG and state laws), the three-month rule, receipt scanning and filing with ELSTER or any tax office.
