Anyone selling a property often asks first of all: do I have to pay tax on the gain? The answer depends above all on how long the property has belonged to you and whether you lived in it yourself. The so-called speculation tax (Spekulationssteuer) is not a separate type of tax at all, but rather income tax on gains from private disposal transactions under Section 23 of the German Income Tax Act (Paragraf 23 Einkommensteuergesetz, EStG – the statute governing German income tax). We explain clearly when it applies, when it does not – and what you should bear in mind regarding the timing of your sale.
What is the speculation tax – and why is it actually called something else?
The term speculation tax is a common shorthand; it does not appear in the legislation itself. In fact it is the income tax on gains from private disposal transactions, governed by Section 23 of the German Income Tax Act (Einkommensteuergesetz, EStG). If you sell a property from your private assets within certain time limits at a gain, that gain counts as other income and is taxed.
Important to understand: there is no fixed speculation tax rate. The gain is added to your taxable income and charged at your personal income tax rate. Depending on your overall situation, this rate can vary considerably. That is precisely why it is worth thinking through the timing of the sale and its tax effect well in advance.
The 10-year period: the key benchmark when selling
The most important benchmark is the ten-year speculation period. If you sell a developed or undeveloped plot of land only after this ten-year period has elapsed, the gain is generally tax-free – regardless of whether you used the property yourself or let it out.
What counts for the calculation is the period between acquisition and disposal. In practice, the decisive dates are those of the two notarised purchase contracts: the contract by which you acquired the property at the time, and the contract by which you sell it on. If more than ten years lie between these two key dates, the sale is generally no longer taxable.
A practical example: if you bought a let flat by notarial deed in March 2014, you can sell it tax-free from March 2024. Anyone approaching this key date should plan the timing carefully – sometimes a few weeks make the difference for a considerable tax burden. We would be glad to assist you with the timing and a realistic valuation of your property.
The owner-occupation exception: tax-free even within the ten years
Even within the ten-year period a sale can be tax-free – namely where you have used the property for your own residential purposes. The law provides for two variants here:
- Continuous owner-occupation: you have lived in the property yourself throughout the entire period between acquisition and sale.
- Owner-occupation in the year of sale and in the two preceding calendar years: it is sufficient if you used the property for your own residential purposes in the year of disposal and in the two calendar years before that.
The second variant is more generous than it first sounds. According to case law, it need not be a full three years. In practice, a continuous period of just over one year can suffice, provided it is spread suitably across three calendar years – that is, covering the middle calendar year in full and the two outer years at least on the respective key date. Use by a child eligible for tax purposes also counts as use for your own residential purposes. Whether the conditions are met in your specific case should be clarified bindingly with your tax adviser.
How the taxable gain is determined
Where a sale falls under speculation taxation, what matters is the actual gain – not the entire sale price. The calculation follows Section 23(3) of the German Income Tax Act (Paragraf 23 Absatz 3 Einkommensteuergesetz):
- Disposal proceeds (the sale price achieved)
- less acquisition or production costs (your purchase price at the time including incidental costs, or your construction costs)
- less disposal costs (for example estate agent fees, notary fees or advertisements for the sale)
An important point for previously let properties: if over the years you have claimed depreciation (AfA – the German tax depreciation allowance) for tax purposes, this reduces the acquisition or production costs to be applied and thereby increases the taxable gain. If the total gain from private disposal transactions in a given year is below the exemption threshold of 1,000 euros (since 2024; previously 600 euros), it remains tax-free. Note: this is an exemption threshold – if it is exceeded, the entire gain is taxable.
Inherited or gifted property: when did the period start running?
Anyone who inherits or is given a property has not acquired it themselves for tax purposes. Here the so-called step-into-the-shoes principle (Fußstapfentheorie) applies: you step into the tax position of your predecessor in title. For the speculation period, what counts is therefore not the date of the inheritance or gift, but the original acquisition date of the deceased or the donor.
This is often an advantage: if, for instance, your mother bought the inherited house as long ago as 15 years, the ten-year period has long since elapsed and you can sell tax-free. Likewise, the previous owner's acquisition costs at the time are adopted for determining the gain. Since inheritance cases are often complex in tax terms, it is worth taking a careful look at the original purchase documents before a sale – and, in case of doubt, consulting your tax adviser.
Several sales? Keep the three-property threshold in view
The speculation tax concerns private disposal transactions. However, anyone who buys and resells several properties within a short period can slip into a different tax category: commercial property trading. A rough guide here is the three-property threshold developed by case law.
Put simply: if more than three properties are disposed of within a close temporal connection – usually around five years – the tax office may assume commercial property trading. The sales then no longer count as private transactions but as income from a trade or business, with different tax consequences. The threshold is not a rigid automatic rule but depends on the circumstances of the individual case. If you are planning to sell several properties, you should discuss this distinction with your tax adviser at an early stage.
Finding the right time to sell – with experience at your side
Whether a sale remains tax-free often comes down to details: the key date of the notarial contracts, the question of owner-occupation, the original acquisition date. Precisely because so much comes together here, a clear view of the right timing is so valuable.
