For tax-driven investors
Using the investment deduction (IAB) with photovoltaics
A business planning an investment can claim part of the cost against tax in advance. Photovoltaic systems are often used for this. OMSI 24 shows you suitable projects.
Register as an investorWhat the IAB is
The investment deduction under section 7g of the German Income Tax Act lets businesses deduct up to 50 percent of the expected acquisition cost of a planned investment from their profit in advance. The tax burden falls in the year the deduction is made; the investment follows later.
Whether and to what extent the IAB is an option for you depends on your business. Limits and deadlines apply, which your tax adviser checks for your case.
Why photovoltaics suits it
- Predictable size: purchase price and capacity of a project are fixed, the investment sum can be quantified early.
- Selection by budget: on the marketplace you filter by purchase price and find projects of the size that matches your deduction.
- Documents for the tax adviser: key figures and documents are available in a structured form.
Find the right projects
On the marketplace you filter by purchase price and project stage. Your contact at OMSI 24 helps you choose.
