F(requently) A(sked) Q(uestions)

Costs for tax advice are deductible as income-related expenses or business expenses if they are incurred for the purpose of determining your income, i.e. if they are professionally related. You cannot deduct privately incurred tax consulting costs from your taxes.

Not in principle. If you make your tax return voluntarily, you can decide each year anew whether the income tax return is worthwhile for you or not. You don’t slide into liability just because you started voluntarily declaring your taxes once.

Important to know: the authority may only query the so-called master data, but not account movements or account balances (Section 93 (7) AO). If the query is made in the context of criminal tax proceedings, the tax authorities’ duty to provide information is not given in this way (Section 24c para. 3 No.21) 12.2010)).

But the tax authorities usually want to go even further back and use a trick: The failure to file a tax return is, in fact, always tax evasion, or at least reckless tax evasion. And then the assessment period can be extended to five or even ten years. (

The tax office has several ways of checking a landlord’s rental income. Since real estate purchases are notarized in Germany, tax offices receive information about this. The tax office may also become aware of the landlord through the tenant’s tax return. (
For real estate, there is the property tax, which is due annually. It is determined by the municipalities themselves. When buying a property, a real estate transfer tax is payable, which is determined individually by each federal state. In addition, the speculation tax and the inheritance tax also relate to real estate.
Of course, you can change the tax advisor in the current year. However, you should always make sure that the timing is sensible. Your old tax advisor may charge a partial fee for the work you have started.
As a rule of thumb, the less expertise or interest you have in tax matters, and the more complex your tax case, the more likely it is to pay to see a tax advisor.
