If you rent out a property, depreciation can be your silent ally in tax reduction – or a missed opportunity that costs you real money every year. Depreciation is not a dry theory from some law but a concrete mechanism that allows you to account for the wear and tear of the building and pay less tax over many years. In this article, we show when the standard depreciation rates are not enough, how to demonstrate the actual technical wear and tear of the property, and how to legally use depreciation to your advantage.
Depreciation – what is it and why should a new property owner know about it from their first tax return?
If you’ve just become the owner of a rental property, it is easy to focus only on rental income, operating costs, and ongoing repairs while completely overlooking one of the most important components of the tax return, namely depreciation. This is a mistake that can really cost a lot – not just once, but year after year. In practice, depreciation is nothing more than accounting for the wear and tear of the building over time, which the legislator recognizes as real rental costs. Importantly, you do not have to physically spend money for these costs to exist – it is enough that the property wears out, which constantly happens anyway, whether you are currently renovating or not.
Many owners view depreciation as a burdensome bookkeeping duty, yet it is one of the strongest tools for reducing taxes. A well-applied property depreciation allows to legally reduce taxable income, often by several tens of thousands of euros over a longer period. And importantly – this is not a solution only for large investors. Even a single rental apartment can bring very tangible advantages if you know from the start how to handle the subject. That is exactly why it is worthwhile to understand what depreciation is, how it works, and when it really „works“ to your advantage instead of viewing it as just a dry definition from a law.
Depreciation of real estate in practice – when are standard depreciation rates insufficient and how can one legally switch to a shorter actual depreciation?
The standard depreciation rates are convenient because they are simple – the legislator assigns buildings a certain useful life, irrespective of their actual technical condition. The problem is that reality often does not fit the tables. An older building, a heavily used property, or a building with a special construction might wear out significantly faster than the „for everyone“ applicable regulations suggest. This is precisely where the opportunity arises for depreciation based on the actual useful life and not a rigid standard.

Tax law gives you the opportunity to deviate from the typical rates, if you can prove that the technical wear and tear of the building progresses faster than the statutory model suggests. This is not a “loophole,” but a legal option confirmed by jurisdiction and the stance of the tax administration. However, it is crucial that the subjective conviction of the owner is not enough. Concrete facts count – the degree of technical wear of the building, its construction, the materials used, usage intensity, or legal restrictions affecting further use of the property. If these elements speak for a shorter lifespan, you have the right to depreciate faster and thereby pay less tax over many years.
In German tax law (AfA – Absetzung für Abnutzung), the basic depreciation rate for residential buildings is currently 2% annually (50 years depreciation period) for properties put into use after December 31, 1924, and for older buildings 2.5% annually (40 years). However, if the taxpayer can – based on a technical report – prove that the actual useful life is shorter, they can apply a higher individual depreciation rate (e.g., 3%, 4%, or more), derived from the documented shortened useful life, according to § 7 paragraph 4 sentence 2 of the EStG.
Depreciation of an apartment and the actual wear and tear of the building – when must the tax office consider a shorter lifespan of the property?
When it comes to depreciation, rental apartments are often dismissed since residential spaces are believed to „always“ have a long useful life. However, reality is often quite different. Buildings from the 50s, 60s, or 70s often show, even after modernizations, advanced wear in the crucial construction elements, such as ceilings, load-bearing walls, or foundations. These elements are crucial in assessing whether an apartment can be depreciated over a shorter actual lifespan.
The tax office does not assess the aesthetics or the standard of furnishings. The determining factor is the technical wear and tear of the building in an objective sense, that is, how long the object can still economically fulfill its function. If a prognosis suggests that before the end of the standard depreciation period there is no viable possibility for further use or adaptation left, the tax administration should take this into account, provided the submitted evidence is convincing and correctly documented. In practice, this means that a well-documented technical condition can indeed result in higher annual tax costs and consequently lower fiscal burden. This solution requires preparation but can make a big difference in rental profitability over the long term.
Rules for determining the technical wear and tear of buildings – how to prove that the depreciation can be higher than „from the table”?
The biggest challenge with applying individual depreciation is not the decision itself, but proving the degree of technical wear and tear of the building in a manner acceptable to the tax office. There is no room for generalities or simplifications here. A crucial role is played by careful documentation, based on technical knowledge and a forecast of future use. In practice, this means the necessity of creating an assessment or expertisethat clearly explains why a particular building wears out faster than the typical rates would suggest.
It is important to note that it’s not just about the current condition, but about the foreseeable time when the property will no longer fulfill its function economically. The technical wear and tear of the building must affect the crucial construction elements, and not just the installation or equipment, which can be relatively easily replaced. However, if the report shows that further use would require disproportionately high investments or become economically unjustifiable, the annual depreciation amount could be significantly higher due to the shortened actual useful life. This solution requires care but offers solid grounds for long-term tax optimization.
Depreciation – what does the tax office see and what does the taxpayer experience in real life?
For the tax office, depreciation is a component of tax calculation, based on regulations and proofs. For you, it is a tool that affects the real cash flow. The difference between the standard depreciation and an individually determined usage period can mean thousands of euros less in tax payments per year. It is important that depreciations have a long-term effect – it is not a one-time depreciation that improves the result only in one year, but a systematic reduction of the tax base throughout the rental period.
Therefore, you should not only pay attention to formalities in depreciation, but consider it as an element of a property management strategy. A conscious approach to the wear and tear of buildings, technical documentation, and usage forecasts allows you to develop a safe, lawful solution that works to your advantage for years. If you plan depreciation well once, you will see the effects in every following tax return – without nerves, without risk, and without the feeling that you left money on the table.
A consciously applied depreciation can significantly reduce rental tax and improve investment profitability, especially when the actual technical wear and tear of the building is considered. In a tax return in Germany, this is of great importance as a correct depreciation directly influences the amount of income declared to the German tax authorities. A well-planned depreciation is not a formality, but a specific tool for long-term tax optimization.
