Decision of the tax office correct?
Question regarding rental and leasing:
For years, I have rented out a granny flat in my owner-occupied house. In my income tax return for 2016, I declared rental income of EU 408,-- cold rent and a lump sum for utilities of EU 92,-- as income, as I have done in previous years. These total EU 1,104,-- per year.
For the deductible expenses, I have allocated expenses for property tax, garbage collection, water, heating (gas), chimney sweep, insurance, interest on loans, immediate deduction for maintenance expenses, and straight-line depreciation based on the rented living area (35.53%). I calculated the following results using Lexware QuickSteuer:
Rental income including utilities: EU 6,000,-
Deductible expenses: EU 6,021,-, Loss: -EU 21,-
The tax office determined a profit of EU 926,--. The explanation in the tax assessment dated 10.10.17 reads: "The utilities for property tax, garbage, etc. were taken into account in the amount of the received utilities of EU 1,104,--. It is to be assumed that the amounts will be balanced out with the tenant as part of a service charge settlement."
Tax repayment according to the tax office: EU 482, + 27.31 solidarity surcharge = EU 509.31, according to my calculations (Lexware) using the above method: EU 249.78.
Note: I have agreed on a flat rent of EU 500,-- including utilities with my tenant (stepson), as a consumption-dependent utility bill for heating, hot water, and water is not possible due to the lack of measuring devices.
Question: Is the tax office's calculation correct? Does it make sense to file an objection? The deadline is on 10.11.17.
