Taxes and Photovoltaics: What You Need to Know as a System Operator

Anyone operating a photovoltaic system must expect certain tax obligations – income tax, trade tax, and VAT related to PV systems all come into play. As soon as you feed electricity into the public grid and generate income, you are often considered an entrepreneur for tax purposes. The choice of legal form directly affects liability and tax treatment. As a small business (Kleinunternehmer), you may benefit from VAT exemptions. To make the most of your PV system, you should be familiar with depreciation options and available tax allowances.

Photovoltaics and Taxes

If you operate your photovoltaic system as a business, the income from feed-in tariffs is subject to taxation — something you should factor in early on. Several types of taxes may be relevant:

Income Tax Return

An income tax return for photovoltaics is required if the PV system is operated through a sole proprietorship or partnership. In this case, profits from the system must be declared as business income and taxed at the individual income tax rate.

Income-Expenditure Statement (EÜR)

A photovoltaic system is typically operated as a small business. This means that profits are determined using the income-expenditure statement. Operating income (primarily feed-in tariffs) is compared to operating expenses (e.g., acquisition costs, annual depreciation of 5% over 20 years, repair and maintenance costs).
Operating expenses can only be deducted for the months in which the PV system is actually in operation.

Trade Tax Return

If the system has been registered as a business, a trade tax return is mandatory. Whether trade tax is actually due depends on the taxable profit. Sole proprietors and partnerships currently benefit from an allowance of €24,500.

Balance Sheet and Corporate Tax Return

If the PV system is operated through a corporation (e.g., GmbH), proper accounting is required. This includes preparing a balance sheet and submitting a corporate tax return.

VAT – Advance Returns and Annual Return

There are also VAT obligations. Under standard taxation, the operator receives a VAT amount in addition to the feed-in tariff, which must be paid to the tax office. Monthly or quarterly VAT advance returns and an annual VAT return are required.
Alternatively, operators can opt for the small business regulation, where no VAT is charged or paid.

Conclusion

Operating a photovoltaic system as a business involves several tax obligations. With professional tax advice or suitable software, these requirements can be fulfilled efficiently and in compliance with the law.

Small Business (Kleinunternehmer) Status

Small business status is a sensible option for many small companies. The regulation was created to relieve businesses with modest revenues from VAT obligations. In practical terms, this means: as a small business operator, you issue invoices without VAT and are not required to submit regular VAT advance returns. This saves time and administrative effort.

To qualify for small business status, the following requirements apply:
– Your gross annual revenue in the previous fiscal year was below €22,000.
– In the current fiscal year, your expected revenue does not exceed €50,000.

Important: Even as a small business, you are still required to submit the annual VAT return. So while some bureaucracy remains, the administrative burden is significantly reduced.
