Assessment of Photovoltaic System Offer

The only problem is that these losses would reduce your income tax if you don’t choose hobby status. Your tip is like advising someone not to file an income tax return even though they would receive a refund.

Please read carefully. That was not a tip, but a statement.
And no, depreciation is not necessarily a good idea in every case; there are catches. Depending on the price at which the system was purchased, whether in cash or with a loan, and how much it produces, it can quickly turn negative after a few years. My tax advisor (who is well versed in photovoltaics and taxes) calculated this for us. In addition, the tax office can be somewhat prickly. That can make life very unpleasant. And I simply trust the expert who has dealt with this several times.

it can quickly lead to tipping after a few years.

That is clear. That is why one switches to the KUR after the fifth full year.

And no, depreciation is not always a good idea, there are catches. Depending on the price at which the asset was acquired, whether in cash or on credit, how much it produces, it can quickly turn after a few years.

I have no idea what you want to tell me with that, nor what it has to do with your previous statement.

Your statement was very simple: profit is not possible, therefore it is a hobby and you have peace.

And that is such a distortion of the facts. Because a loss reduces my tax burden, of course I declare it in the tax return. A profit up to roughly €400 is tax-free, above that it is taxed as income. The idea of a hobby only arises if you have no desire for the paperwork and consciously accept financial disadvantages for convenience.

Nowhere in this discussion does the topic of depreciation come up. And even on that topic: what could go wrong. Please give an example of what catches there are supposed to be.

The whole topic of VAT is then another new field, independent of everything mentioned before.

Um, I basically agree with the Non-Enthusiasts Party, but how else are you supposed to report a loss if you don’t depreciate the asset?

You misunderstood me. The previous discussion was solely about the business management result. The topic of depreciation comes before that, in the calculation of profit/loss. Arguments pro/con depreciation issues are simply misplaced when discussing the utilization of the calculation result and not the calculation method at all.

Stiftung Warentest recommends 7 years in the photovoltaic calculator (point "Value-added tax exemption from the 7th calendar year?*"):
"As a small business owner, you can be exempted from value-added tax again after five calendar years. It is usually most advantageous to apply for the exemption starting from the 7th calendar year. Then no input tax adjustment takes place."
