Income from the operation of the facilities is thus no longer included in income tax (information on this is available here ).
This regulation has no effect on sales taxation!
The operators of such plants are still entrepreneurs if they feed the electricity generated by the plant in whole or in part, regularly and not only occasionally, into the electricity grid against payment (Section 2.5 (1) UStAE). An intention to make a profit is not required to qualify as an entrepreneur
The system operators are - insofar as they do not generate sales from other activities - regularly small entrepreneurs within the meaning of Section 19 UStG, so that there is no obligation to submit advance VAT returns and annual VAT returns
In order to be able to deduct the total VAT attributable to the acquisition or production costs of the plant as input tax, it is possible to opt for standard taxation. If the entrepreneur makes use of this option, he is bound to this decision for at least five calendar years. As a new entrepreneur, he is obliged to submit quarterly advance VAT returns and an annual VAT return within the first two years. In addition, he must pay tax on his initial sales and on the private consumption of the electricity generated. In return, he also receives the sales tax on the feed-in tariff from the grid operator
