The topic briefly and concisely
The profit from a property sale is tax-free if the property has been owned for more than 10 years or if it was occupied by the owner during the year of sale and the two preceding years.
To calculate the taxable profit, subtract the purchase and selling costs from the sale price; the remainder will be taxed at your personal income tax rate.
For inherited properties, the purchase date of the deceased is considered, which often exempts heirs from capital gains tax.
Selling a property is often associated with a substantial profit, but the joy is quickly dampened by the looming question of tax liability. The so-called speculation tax can significantly reduce your actual profit. Do you know how to take advantage of the 10-year rule or completely avoid tax liability through owner-occupation? A precise calculation is not a luxury but a necessity. We guide you through the exact calculation of your net sale proceeds and show you the decisive factors that can account for thousands of euros.
The speculation tax: An overlooked factor in property sales
If you sell a property within ten years of purchase, the profit is subject to income tax, colloquially known as speculation tax. This regulation according to § 23 EStG is intended to tax short-term speculative transactions and can cost up to 45% of your profit. The decisive factor here is not the date of the contract conclusion, but the notarization by the notary. Knowing this deadline precisely is the first step to making your sale tax-free. Calculating the taxable profit is the next logical step.
Accurate Profit Calculation: The Formula for Your Net Income
The taxable profit is not simply the selling price. The correct formula is: Selling price minus the original acquisition costs and current disposal costs. The result is added to your annual income and taxed at your personal tax rate. Even €10,000 in deductible costs can reduce your tax burden by up to €4,500.
You can apply the following items to reduce the profit:
Original purchase price of the property
Original acquisition incidental costs (approx. 1.5% notary and land registry fees, up to 6.5% property transfer tax)
Selling costs (e.g., broker fees, advertisements, energy certificates)
Subsequent construction costs (e.g., renovations that increase value)
Prepayment penalty to the bank
Fortunately, there are legal ways to bypass the entire tax burden if certain conditions are met.
Securing Tax Exemption: The Two Key Exceptions
You can keep the sales profit completely tax-free if one of two conditions is met. The most well-known is the holding period of over 10 years for rented properties. If the notarised purchase was more than a decade ago, the tax obligation is completely waived. The second, often more relevant exception is personal use. If you have lived in the property in the year of sale and in the two preceding calendar years, the profit is also tax-free. A period of just 13 months can be sufficient for this if it spans three calendar years (e.g. December 2023 to January 2025). These rules are particularly important for heirs, as the next section shows.
Special Case Inheritance: How Heirs Can Optimally Use the Speculation Period
If you have inherited a property, you often unjustly fear high tax payments upon sale. For calculating the speculation period, the inheritance event is not the deciding factor, but rather the original purchase date by the deceased. If the deceased had owned the property for over 10 years, you can sell it immediately tax-free. The deceased's personal use rule is also transferred to you. So, if the deceased lived there themselves for the last two years plus the year of death, no speculation tax applies to you. This continuity protects heirs from an unexpected tax trap when selling. To declare the value accurately for inheritance tax, a precise valuation is essential.
Strategic Planning: Actively maximise sales proceeds after tax
Forward-looking planning can increase your net profit by tens of thousands of euros. Before selling, carefully check whether you are about to reach the 10-year deadline and whether delaying is worthwhile. Meticulously collect all evidence of acquisition, sale, and modernization costs to reduce the taxable gain. A professional valuation serves not only for pricing but also as proof for the tax office. A data-driven evaluation by Auctoa safeguards your calculations and identifies all deductible cost points.

Conclusion: Accurate calculation is the key to full revenue
Determining the post-tax sales proceeds is more than a mere calculation task – it is a strategic process. Knowledge of speculation periods, owner-occupancy rules, and deductible costs determines the actual financial success of your property sale. Therefore, an accurate calculator for the post-tax sales proceeds of real estate is essential. Act informed and secure the profit that is rightfully yours.

FAQ
How do I calculate the taxable profit accurately?
The formula is: Selling price - Acquisition costs - Disposal costs = Taxable profit. Acquisition costs include the original purchase price plus incidental purchase costs (notary, property transfer tax). Disposal costs include, for example, agent and notary fees for the current sale.
Does a holiday apartment count as personal use?
Yes, even a holiday apartment or a second home used personally can avoid the capital gains tax on sale. It is important that the property was available for your own use during the relevant period and was not let out to third parties on a permanent basis.
What happens if I sell only part of the property?
When selling a part of a plot of land or a property, the acquisition costs are calculated proportionally. The resulting profit is subject to the same capital gains tax rules as a complete sale.
Does the speculation tax also apply to a gift?
No, a gift does not trigger speculation tax. However, the recipient assumes the acquisition data of the donor. If the recipient sells the property later, the holding period of the donor is taken into account to check the 10-year period.
Is there an allowance for speculation tax?
There is no specific allowance for profits from property sales. There is only an exemption limit of 600 euros per year for all private disposal transactions combined. If this limit is exceeded, the entire profit is subject to tax.
Do I always have to declare the sale on the tax return?
You must declare the sale in the 'Other Income' section of your tax return if the sale takes place within the 10-year period. Even if no tax is incurred due to personal use, it is advisable to include it for examination by the tax office.
