Costs for long-distance family calls
Enter here the amount of the expenses you incurred for the telephone calls with your relatives that you made instead of a trip home to your family.
Important: If you do not travel home on a weekend, you can claim the cost of a telephone call for up to 15 minutes in your tax return. However, this is only possible if there are relatives living in your household. Single persons without relatives are not entitled to this deduction.
