If the employee receives less than the legally defined additional subsistence expenses and accommodation allowances for his/her travels, then he/she can claim the difference as income-related expenses in his/her tax return.
If the option Show income-related expenses is selected, then the amount that the employee can show as income-related expenses in his/her tax return is printed in the travel expense report.
If the expense groups are assigned on the Days level, the income-related expense deduction is only calculated for the days on which an expense group has been assigned that has the Show income-related expenses option switched on. Therefore, at least one expense group with the option Show income-related expenses must be selected in the trip. Please note that the income-related expenses are not calculated for the days on which a expense group is selected without the option Show income-related expenses.
