Most high earners in Germany pay a mid-five-figure sum to the tax office every year, without knowing that a single paragraph in the Income Tax Act would legally return a substantial part of that amount to them.
This paragraph is § 7i ITA. It governs the increased depreciation rates for listed historic buildings. And it is one of the most powerful and at the same time least understood tax provisions in German law.
I see it again and again in initial conversations: clients with 150,000, 250,000, 400,000 euros of gross income — physicians, lawyers, entrepreneurs, executives — who consult tax advisors regularly, but have never seriously considered § 7i. Not out of negligence, but because most advisors do not actively offer it in their day-to-day work.
What the legislator wanted
The logic behind § 7i is not fiscal but cultural-political. Germany possesses an extraordinary inventory of historic building substance — Gründerzeit districts, baroque townhouses, classicist villas, industrial-architectural witnesses of the 19th century. Preserving this substance costs money. A great deal of money.
Instead of financing this preservation through state subsidies alone, the legislator chose a smarter path: it invited private investors to finance the renovation — and in return offered an extraordinary tax leverage. Anyone who renovates a registered historic building can fully depreciate the renovation portion against their taxable income over twelve years.
The state does not want any taxes on heritage real estate — it gives them back.
— Manfred Braun
This construction is not a loophole. It is constitutional intent. The legislator deliberately created it because they recognised: without private participation, the German heritage stock could not be preserved in its current form.
How the mechanism works
The construction is simpler than most think. With a heritage-protected property, the purchase price is divided into three components: land, old building substance, and renovation portion. Only the renovation portion is depreciable under § 7i — and this is precisely where the leverage lies.
The renovation portion in a typical heritage property is between 60 and 80 percent of the purchase price. In the first eight years after purchase, you can deduct 9 percent of this amount annually against your income, and another 7 percent in the four following years — a total of 100 percent over twelve years.
The Six Requirements
I.Registered historic building with official certification
II.Renovation according to heritage protection standards
III.Renovation costs separately stated in the purchase contract
IV.Rental as source of income (no owner-occupation)
V.Certification under § 7i by heritage authority
VI.Minimum holding period of twelve years
With a gross income of 150,000 euros and a property of 400,000 euros purchase price and 70 percent renovation portion, this results in annual tax savings of around 11,000 euros in the first eight years — from the special depreciation alone. Over twelve years, the savings sum up to a six-figure amount.
This is not tax structuring in a grey area. This is the direct application of a paragraph that has been in effect for decades and has been confirmed by every federal government — regardless of political colour.
What makes § 7i special
There are several tax incentives for real estate in Germany. Linear depreciation for classic income properties. Declining depreciation for new construction. Special depreciation for KfW-certified buildings under § 7b. But none of these provisions reaches the impact of § 7i. What makes this paragraph unique:
- The depreciation amount — up to 100% of the renovation portion
- The depreciation speed — fully written off in twelve years
- The stability of the legal framework — unchanged for decades
- The combinability with other tax advantages such as operating expenses
- The decoupling from market value — the renovation portion remains depreciable even if the property appreciates
This combination does not exist in any other asset class. Equities are subject to capital gains tax. So are ETF returns. Fixed deposits have yielded real negative returns for years. Classic income real estate offers 2 percent linear depreciation — solid, but no tax leverage.
Once you have understood § 7i, you no longer view taxes as a fixed quantity.
What the market does not understand
In my experience, the use of § 7i rarely fails because of money, but almost always because of information. High earners often do not know it exists. And when they hear about it, they consider it an exotic construction — something that only works for very wealthy people or carries legal risk.
Both are wrong. The paragraph is structurally meaningful for incomes from around 100,000 euros gross. And it is legally one of the oldest and most settled provisions of income tax law altogether.
What it takes is an understanding of the mechanism — and the willingness to think in long-term investment horizons. Anyone seeking quick gains is poorly advised with heritage real estate. Anyone wanting to build wealth and at the same time strategically reduce their tax burden will find here one of the few remaining legal tools with this kind of impact.
What you can do now
If you regularly pay five-figure amounts to the tax office, it is worth having § 7i seriously examined once. Not in a quick run-through. But structured, with a realistic model calculation based on your individual income situation.
Ideally, after this initial conversation you will understand whether the model fits you — and if so, in what order of magnitude. If not, I will tell you honestly. There are constellations in which heritage real estate is not the right tool. To say that openly is part of my understanding of consultation.
But for most high earners I work with, the question is not whether § 7i works. The question is why they have not been using it for a long time already.
