Calculator for post-tax sale proceeds on real estate
Are you selling your property and worried that the tax office will claim a large portion of the profit? Many owners are unaware of the legal deductions and end up giving away up to 45% of the sale profit to the tax authorities. This article will show you how to accurately calculate your net profit after tax on property sales with a precise calculator.
With access to Google, BORIS, and Deep Research.
The profit from a property sale is tax-free if the property has been held for over 10 years or has been owner-occupied in the year of sale and the two previous years.
To calculate the taxable profit, deduct the acquisition and selling costs from the sale price; the remainder is taxed at your personal income tax rate.
For inherited properties, the date of purchase by the deceased is considered, which often exempts heirs from capital gains tax.
The sale of a property is often associated with a significant profit, yet the joy is quickly overshadowed by the emerging question of the tax burden. The so-called speculation tax can significantly reduce your actual profit. Do you know how to make use of the 10-year period or completely avoid tax liability through personal use? An accurate calculation is not a luxury but a necessity. We guide you through the precise calculation of your post-tax sale proceeds and show you the key factors that can determine thousands of euros.
If you sell a property within ten years of purchase, the profit is subject to income tax, colloquially known as speculation tax. This regulation under § 23 EStG is intended to tax short-term speculative transactions and can cost up to 45% of your profit. The key factor here is not the date the contract was signed, but the notarisation by the notary. A precise understanding of this deadline is the first step to making your sale tax-free. Calculating the taxable profit is the next logical step.
The taxable profit is not simply the sale price. The correct formula is: Sale price minus the original purchase costs and current sale 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.
The following items can be used to reduce the profit:
Original purchase price of the property
Ancillary purchase costs at the time (approx. 1.5% notary and land registry fees, up to 6.5% property transfer tax)
Costs for the sale (e.g. agent fees, advertisements, energy performance certificate)
Subsequent production costs (e.g. renovations that increase value)
Prepayment penalty to the bank
Fortunately, there are legal ways to avoid the entire tax burden if certain conditions are met.
You can retain the sale profit entirely 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 took place more than a decade ago, the tax obligation is completely eliminated. The second, often more relevant exception is owner-occupation. If you have lived in the property both in the year of sale and 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 significant for heirs, as the next section shows.
If you have inherited a property, you often fear high tax payments upon sale, often unjustly. For the calculation of the speculation period, it is not the inheritance event that counts, but the original purchase date by the deceased. If the deceased had already owned the property for over 10 years, you can sell it immediately tax-free. The self-utilisation rule of the deceased is also transferred to you. If the deceased therefore lived in it for the last two years plus the year of death, no speculation tax is due for you. This continuity protects heirs from an unexpected tax trap upon sale. To correctly state the value for inheritance tax, an accurate valuation is essential.
Strategic planning can increase your net proceeds by tens of thousands of euros. Carefully check before selling if you are about to reach the 10-year period and whether the deferral is worthwhile. Meticulously gather all evidence of acquisition, sale, and modernization costs to reduce the taxable profit. A professional valuation not only helps determine the price but also serves as proof to the tax office. A data-driven valuation from Auctoa secures your calculations and identifies all deductible cost points.

Determining the post-tax sale proceeds is more than just a mathematical task – it is a strategic process. Knowing about speculation periods, personal use rules, and deductible costs determines the actual financial success of your property sale. Therefore, an accurate calculator for post-tax sale proceeds in real estate is essential. Act informed and secure the profit that is rightfully yours.

Wie berechne ich den steuerpflichtigen Gewinn exakt?
The formula is: sale price - purchase costs - selling costs = taxable profit. Purchase costs include the original purchase price plus additional purchase costs (notary, real estate transfer tax). Selling costs are, for example, brokerage and notary fees for the current sale.
Zählt eine Ferienwohnung zur Eigennutzung?
Yes, even a self-used holiday home or a second home can avoid the speculation tax upon sale. It is important that the property was available to you for personal use during the relevant period and was not permanently rented out to third parties.
Was passiert, wenn ich nur einen Teil des Grundstücks verkaufe?
When selling part of a plot of land or a property, the purchase costs are calculated proportionally. The resulting profit is subject to the same rules of speculation tax as a full sale.
Fällt die Spekulationssteuer auch bei einer Schenkung an?
No, a gift does not trigger speculation tax. However, the recipient assumes the donor's acquisition data. If the recipient sells the property later, the holding period of the donor is considered to check the 10-year period.
Gibt es einen Freibetrag für die Spekulationssteuer?
There is no specific allowance for profits from real estate sales. There is only a threshold of 600 euros per year for all private sales transactions combined. If this limit is exceeded, the entire profit is taxable.
Muss ich den Verkauf immer in der Steuererklärung angeben?
You must report the sale in Schedule SO (Miscellaneous Income) of your tax return if the sale takes place within the 10-year period. Even if no tax is due due to personal use, reporting is advisable for examination by the tax office.
