FAQ
Find answers to the most common questions about AfA Sparen, useful life appraisals, and using depreciation for tax purposes.
In our calculator you can generally choose any valuation date retroactively back to 01/01/2020. If you acquired the property after that, it usually makes sense to use the date on which benefits and burdens transferred (“transfer of possession, risk and rewards”). Otherwise, we often recommend using January 1 of a given year. Important: all inputs must reflect the circumstances as of the chosen valuation date. If you are unsure, clarify the best date with your tax advisor.
For tax purposes, land is generally assumed not to wear out. Buildings, however, deteriorate over time due to age, use, and technical obsolescence. Therefore, only the building portion (not the land) is depreciable.
The assessment follows recognized valuation principles, including key concepts reflected in the German valuation framework (e.g., ImmoWertV principles). Core inputs include year of construction/age, construction type, maintenance level, defects and damages, modernizations (type, scope, timing), usage type, and technical equipment. Modernizations can extend useful life; significant deficiencies can shorten it.
In principle, yes—provided the report is technically sound, plausible, and transparent. Following the German Federal Fiscal Court ruling of 28/07/2021 (case IX R 25/19), a shorter actual useful life can be applied when supported by an appropriate proof. Please note that laws, administrative practice, and case law can change over time; seek tax advice if needed.
Yes—this can be possible, especially for tax years that have not yet become final (i.e., where no final tax assessment notice is in place). In such cases, a shorter actual remaining useful life can be applied and the remaining tax basis of the building may be reallocated accordingly. In practice, depreciation is determined on a yearly basis and can be reassessed. Please coordinate the specific implementation with your tax advisor.
