Find answers to the most common questions about Gut8en, useful life appraisals, and using depreciation for tax purposes.
You receive a well-documented appraisal report on the property’s actual remaining useful life as a PDF via email. In addition, you get a practical cover letter template (pre-drafted by a tax advisor) that you can submit together with the report as part of your tax filing.
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.
The free preliminary assessment in our calculator needs no documents at all — only basic building details (year of construction, construction type, areas, modernizations, condition, use). If you then commission the appraisal, the purchase contract is the most important document: it determines how the purchase price is split between land and building, and therefore the base your depreciation is calculated on. Floor plans, a living area calculation, an energy certificate, the sales listing and — for apartments — owners association meeting minutes are also helpful. We do not need building authority records. We tell you upfront what is actually required in your case.
In many cases, the appraisal fee can be deducted—typically as income-related expenses for rental income or as business expenses for business-use properties—because it relates to determining and optimizing depreciation. The exact treatment depends on your situation; consult your tax advisor if in doubt.
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.
