Anyone who sells a property at a profit within ten years of purchasing it may have to pay tax on this profit as a private disposal transaction – quickly amounting to a five-figure sum. Completely legally, however, this so-called speculation tax can often be avoided or significantly reduced. We show you which strategies work in 2026, when they apply and what you should pay attention to.
What is speculation tax?
“Speculation tax” is the colloquial name for income tax on private disposal transactions pursuant to Section 23 EStG. It is not a separate type of tax: The profit is simply added to your other income and taxed at your personal tax rate – depending on income, up to 45 percent plus the solidarity surcharge and, where applicable, church tax.
The sale is taxable only if no more than ten years lie between acquisition and disposal. The dates of the two notarized purchase agreements are decisive, not the entry in the land register. The taxable profit is calculated in simplified form as follows:
- Sale price
- minus the original acquisition or production costs
- minus income-related expenses and disposal costs (such as the broker’s commission or early repayment penalty)
An important detail: For rented properties, the purchase price is reduced by the depreciation (AfA) already claimed. Anyone who has claimed depreciation for years thereby increases their taxable disposal gain.
Five legal ways to avoid speculation tax
Whether and how much tax is payable depends heavily on preparation. These strategies can be used individually or in combination.
Option 1: Wait until the ten-year period has expired
The cleanest approach is also the simplest: Anyone who sells the property only after ten years have elapsed pays not a cent of speculation tax on the profit – regardless of its amount. The period begins on the date of the notarized purchase agreement and ends exactly ten years later.
Check the date of your purchase agreement before listing the property. If the period expires only a few weeks or months in the future, it may be worthwhile to deliberately schedule the notary appointment after the deadline. Signing the agreement even slightly too early makes the entire profit taxable.
Option 2: Establish owner-occupancy
Even within the ten-year period, the sale remains tax-free if you have occupied the property yourself. Section 23 EStG provides two alternatives for this:
- The property was used exclusively for your own residential purposes throughout the entire period between acquisition and sale, or
- it was used for your own residential purposes in the year of sale and the two preceding years.
The second alternative is the practical lever. It does not require three full calendar years: The middle of the three years must be occupied by you continuously; in the year of sale and the preceding year, a consecutive period in each is sufficient. Thus, mathematically, a period of slightly more than one year is enough—provided it is distributed correctly across the calendar years. Anyone who moves into a rented apartment themselves before the sale can thus avoid the tax entirely. Use for one's own residential purposes also includes providing the property free of charge to a child for whom you receive child benefit.
Option 3: Spread out the sale over time
If the sale can neither be postponed nor saved through owner-occupancy, it is worth looking at the timing. Because the gain is taxed at your personal tax rate, the year in which you sell makes a major difference. Selling in a year with low other income—for example, after retirement, during parental leave, or during a career break—noticeably reduces the tax rate on the gain.
Anyone who owns several properties should also spread out the sales: If you sell more than three properties within five years, the tax office may classify this as a commercial property trade under Section 15 EStG. In that case, the ten-year tax exemption is lost completely, and trade tax is also due. With sufficient time between sales, you remain within tax-favorable private assets.
Option 4: Reduce the taxable gain
If speculative tax is applicable in principle, the tax base can at least be reduced. You may deduct all costs associated with the sale from the sale proceeds, for example:
- Brokerage commission and sales advertisements
- Costs for the energy performance certificate and valuation report
- Early repayment penalty for the premature repayment of the loan
- Notary and land registry costs borne by the seller (for example, for the deletion ofReal estate liens)
Value-enhancing modernizations and conversions also increase the acquisition or production costs and thus reduce the profit. Caution: Extensive repairs within the first three years after purchase may qualify as acquisition-related production costs and must be treated separately. Collect all receipts carefully – every deductible euro reduces the tax.
Option 5: Properly classify inheritance and gifts
Anyone who inherits or receives a property as a gift does not start a new ten-year period. The transfer free of charge is not an acquisition within the meaning of Section 23 EStG; instead, you are credited with the holding period of the deceased or donor. If the deceased had already owned the property for more than ten years, you can sell it immediately tax-free. If the legal predecessor purchased it less than ten years ago, you take over the remaining period – and should use the original purchase agreement to calculate the period.
Calculation example: How the period affects you
Assume you purchased a rented condominium in 2020 for 300,000 euros and sell it in 2026 for 400,000 euros. Over the six years, you depreciated 30,000 euros, and you pay an estate agent’s commission of 12,000 euros for the sale.
- Sale price: 400,000 euros
- less acquisition costs (300,000 euros − 30,000 euros depreciation): 270,000 euros
- less selling costs: 12,000 euros
- taxable profit: 118,000 euros
At a marginal tax rate of 42 percent, this would amount to around 49,560 euros in tax. If, on the other hand, you wait until 2030 – i.e. until after the ten-year period has expired –, the entire profit remains tax-free. This example shows why patience or smart structuring is particularly worthwhile when it comes to speculation tax.
Advantages and disadvantages of avoidance strategies
Not every strategy suits every situation. Weigh up the following:
- Advantage – full tax exemption: Waiting out the period and occupying the property yourself make the profit completely tax-free, without any grey area.
- Advantage – predictability: Anyone who plans the sale early can deliberately control deadlines and the year of sale.
- Advantage – receipts are worthwhile: Carefully collected selling and modernization costs reduce the tax even when they are unavoidable.
- Disadvantage – time commitment: Waiting out the period or moving in for personal use costs months to years and ties up capital.
- Disadvantage – market risk: Anyone who waits solely because of the tax risks fallingPrices or rising interest rates.
- Disadvantage – Complexity: Particularly with rented properties, inheritances, or multiple sales, the rules are prone to errors—tax advice is advisable here.
FAQ on the Speculation Tax
How high is the speculation tax?
There is no fixed rate. The profit is added to your taxable income and taxed at your personal tax rate—from around 14 to 45 percent, plus the solidarity surcharge and possibly church tax.
Is there a tax-free allowance?
There is an exemption threshold of 1,000 euros per year (raised from the previous 600 euros since 2024). If the total profit from private sales transactions is below this amount, it remains tax-free. However, if the threshold is exceeded, the full amount is taxable—which is the rule for real estate.
Does a home office count as detrimental use?
No. According to current case law, a home office in an otherwise owner-occupied property does not preclude tax exemption. The property is still considered to be used for the owner’s own residential purposes.
Exactly when does the ten-year period begin and end?
The period begins on the date of your notarized purchase contract and ends exactly ten years later. A sale on the day after the period expires is already tax-free—a sale one day too early makes the entire profit taxable.
Do I have to report the sale on my tax return?
Yes. You must also report a tax-free sale within the period—such as due to owner-occupancy—in Annex SO of your income tax return. The tax office will independently verify the requirements for tax exemption.
Conclusion: With planning, the tax can usually be avoided
The speculation tax primarily affects those who sell under time pressure and without preparation. The strongest levers are waiting until the ten-year period has elapsed and owner-occupancy—both make the profit completely tax-free. If the sale cannot be postponed, the right timing and careful deduction of selling costs reduce the burden. Since mistakes can quickly occur with inherited properties and multiple sales, you should seek tax advice early in cases of doubt—the savings usually exceed the advisory costs many times over.
