Property capital gains tax (Spekulationssteuer): the ten-year period explained
If you sell a rented property before ten years have passed since purchase, you may have to pay income tax on the gain — commonly called property capital gains tax (Spekulationssteuer). For private investors, this is one of the most important tax rules because it helps determine when a sale may make sense for tax purposes. This guide explains what the tax involves, how to calculate the 10-year period correctly, the exemption for owner-occupied property and how taxable gains are calculated, including the often overlooked effect of depreciation (AfA).
A note before we begin: tax rules can change and depend heavily on individual circumstances. Please check all information against current rules and consult a tax adviser before making specific decisions.
What property capital gains tax means
The German term “Spekulationssteuer” is slightly misleading: this is neither a separate tax nor a separate tax rate. It refers to taxation of private disposal transactions under section 23 EStG. If you sell a privately held property at a profit within the statutory period, that gain counts as other income and is taxed together with your remaining income at your personal income tax rate.
This has an important consequence: there is no general answer to how much tax will be due. It depends on your total taxable income in the year of sale. If the property is sold only after the period has expired, a gain on privately held property is generally tax-free — one reason many investors plan for the long term from the outset.
Calculating the 10-year period correctly
For rented properties, the capital gains tax period is ten years. It begins with acquisition and ends with sale; the dates of the notarised purchase contracts determine both points. Neither the key handover, the purchase price payment nor the land register entry is relevant to calculating the period.
For example, if your purchase contract was notarised in March 2016, the period runs until March 2026. The sale falls outside the ten-year period only if the notarised sale contract is executed after that point. If you are considering selling shortly before expiry, plan the notarisation date carefully: a few days can determine whether tax is due. If in doubt, discuss the timing with your tax adviser first.
Owner-occupation exemption: when a sale is not a taxable private disposal
The law provides an important exemption for owner-occupied property. If you used the property as your own home in the year of sale and the two preceding years, the sale remains tax-free even within ten years. The exemption mainly concerns owner-occupiers; it does not apply to investments that have been rented out throughout.
Whether you meet the owner-occupation requirements depends on the details — for example, exactly how the property was used during the three years concerned. Before planning a sale, review these questions with your tax adviser under the current rules rather than relying on rules of thumb.
How the gain is calculated — and why depreciation increases it
In simplified terms, the taxable gain is the sale price less acquisition costs and costs directly associated with the sale. One point is often overlooked: depreciation (AfA) claimed during the rental period reduces the acquisition costs used in the calculation, increasing the taxable gain. The depreciation you deducted as rental expenses over the years is therefore effectively added back when you sell within the period.
A simple numerical example
- Sale price: €300,000
- Original acquisition costs including incidental costs: €250,000
- Depreciation claimed during ownership: €20,000
- Reduced acquisition costs: 250,000 − 20,000 = €230,000
- Selling costs: €5,000
Taxable gain = 300,000 − 230,000 − 5,000 = €65,000
Without the depreciation adjustment, the gain would be €45,000: the €20,000 depreciation claimed increases the taxable gain by exactly that amount. The tax due depends on your personal income tax rate in the year of sale; giving a general percentage would be misleading. This example is deliberately simplified and cannot replace an individual tax calculation.

The three-property threshold: beware of commercial property trading
Private sellers should know a second threshold alongside the capital gains tax period: the three-property threshold. Anyone selling more than three properties within around five years risks the tax office treating this as commercial property trading, with significant tax consequences that can go beyond income tax on individual gains. The distinction depends on the circumstances and case law. If you plan several sales, or intend to sell inherited or gifted properties, discuss the situation with a tax adviser early.
What this means for buy-and-hold investors
For long-term investors, the ten-year period is more a planning framework than a threat. Buying an investment property for a long holding period from the outset — with a sound location, conservative figures and sustainable financing — helps avoid having to sell at short notice and potentially incur tax. After ten years, a privately held property can generally be sold tax-free; whether, when and at what price a sale succeeds still depends on market conditions. Property values can fluctuate, and properties have limited liquidity: a gain on sale is not guaranteed.
