The preclusive period for claiming reimbursement of costs is 6 months. The period begins on the day after the end of the business trip. As compensation for additional expenses for meals, business travellers receive a daily allowance for all domestic business trips, the amount of which is measured in accordance with the provisions of the Income Tax Act. Travel and flight costs: Class 1 train journeys may only be booked if the train journey itself takes at least 2 hours (excluding transport time from the main departure point). Otherwise, only journeys in 2nd class will be reimbursed. For flights, bookings of business flights of 6 hours or more are covered. Overnight allowances can only be granted for necessary overnight stays.
