When purchasing a property in Baden-Württemberg, the tax authorities charge 5.0 percent of the purchase price as real estate transfer tax – for an apartment in Stuttgart, this can quickly amount to 15,000 to 20,000 euros. The tax is one of the largest ancillary purchase costs and becomes due before you are entered in the land register as the new owner. We explain how the amount is calculated, where Baden-Württemberg ranks in comparison with the other federal states, and what sums you specifically need to expect in Stuttgart and on Lake Constance.
What is real estate transfer tax?
Real estate transfer tax is a one-time tax incurred when purchasing a plot of land or property. Its legal basis is the Real Estate Transfer Tax Act (GrEStG). In Section 11 GrEStG, it provides for a nationwide standard rate of 3.5 percent – since the federalism reform of 2006, however, the federal states have been allowed to set the rate themselves (Article 105 (2a) of the Basic Law). Baden-Württemberg has made use of this option and raised the rate from 3.5 to 5.0 percent on November 5, 2011. This rate remains unchanged in 2026.
Almost every transfer of ownership for consideration is taxed: the purchase of a house, an apartment, an undeveloped plot of land or a co-ownership share. The tax base is the value of the consideration – as a rule, therefore, the purchase price notarized in the contract. Without payment of the real estate transfer tax, you will not receive clearance for registration in the land register.
How to calculate real estate transfer tax in Baden-Württemberg
The calculation is simple: multiply the purchase price by 5.0 percent. The tax amount is then rounded down to the nearest whole euro.
- Purchase price 300,000 euros × 5.0% = 15,000 euros
- Purchase price 450,000 euros × 5.0% = 22,500 euros
- Purchase price 600,000 euros × 5.0% = 30,000 euros
Important: Only the plot of land together with permanently attached components is taxed. Movable accessories – such as a fitted kitchen, awnings or a sauna – are not included in the tax base. If such inventory is listed separately in the purchase contract and assigned a realistic value, the real estate transfer tax decreases accordingly. The tax office recognizes an appropriate proportion; for a purchase price of 400,000 euros, amounts of up to around five percent are generally unproblematic based on experience.
Calculation examples: Stuttgart and Lake Constance
In the country’s high-price regions, the five-percent rate adds up to considerable amounts. The following examples are based on average prices per square meter at the beginning of 2026:
- Condominium in Stuttgart: 80 m² at around 4,700 euros/m² results in a purchase price of approximately 376,000 euros. The real estate transfer tax amounts to 18,800 euros.
- Single-family house in Stuttgart: A purchase price of 780,000 euros incurs 39,000 euros in real estate transfer tax.
- Condominium in Constance: 90 m² at around 5,650 euros/m² corresponds to approximately 508,500 euros. This results in 25,425 euros in real estate transfer tax.
- Apartment in Überlingen (prime location): With a purchase price of 650,000 euros, 32,500 euros is due.
Real estate transfer tax is only one part of the ancillary purchase costs. Notary and land registry fees of approximately 1.5 to 2.0 percent in total are added, as is – if a broker is commissioned – the proportional commission. Overall, buyers in Baden-Württemberg should expect ancillary purchase costs of around 8 to 12 percent of the purchase price and include these in the financing from the outset.
Baden-Württemberg in comparison with other federal states
At 5.0 percent, Baden-Württemberg is in the national middle range. Bavaria remains the only state to charge the original rate of 3.5 percent, while several states charge up to 6.5 percent. The rates in 2026 are distributed as follows:
- 3.5 %: Bavaria
- 5.0 %: Baden-Württemberg, Lower Saxony, Rhineland-Palatinate, Saxony-Anhalt, Thuringia
- 5.5 %: Bremen, Hamburg, Saxony
- 6.0 %: Berlin, Hesse, Mecklenburg-Western Pomerania
- 6.5 %: Brandenburg, North Rhine-Westphalia, Saarland, Schleswig-Holstein
A direct comparison for a purchase price of 500,000 euros shows how significantly the rate matters: Buyers pay 17,500 euros in Bavaria, 25,000 euros in Baden-Württemberg and 32,500 euros in North Rhine-Westphalia. The difference between the least expensive and most expensive federal state is therefore 15,000 euros – one reason why the tax rate can certainly play a role when moving across a state border.
When is real estate transfer tax due?
You do not have to initiate the process yourself – after notarization, it proceeds largely automatically:
- The notary notarizes the purchase agreement and notifies the competent tax office.
- The tax office assesses the tax and sends the real estate transfer tax notice to the buyer.
- The tax is due one month after the notice is issued.
- Once payment has been received, the tax office issues the Issues a certificate of clearance.
- Only with this certificate does the land registry office register the buyer as the new owner.
According to Section 13 GrEStG, both contracting parties are generally jointly and severally liable for the tax. In almost all purchase contracts, however, payment is imposed on the buyer. If the buyer does not pay, the tax office can, if necessary, hold the seller liable – one reason why registration in the land register is linked to the tax having been paid.
Saving real estate transfer tax: What options are available
Real estate transfer tax cannot be completely avoided in a normal property purchase. In some situations, however, it does not apply in the first place or can be reduced:
- Deduct movable inventory: List the fitted kitchen, furniture, sauna or garden house separately in the purchase contract and state a realistic value (see above).
- Maintenance reserve for condominiums: The portion of the purchase price attributable to the reserve already accumulated may reduce the tax base. However, the tax authorities are increasingly interpreting this point narrowly – seek advice here.
- Acquisition within the family: Under Section 3 GrEStG, purchases by a spouse or civil partner and by relatives in the direct line (parents, children, grandchildren) are tax-exempt.
- Inheritance and gift: Anyone who inherits or receives a property as a gift pays no real estate transfer tax – inheritance or gift tax applies instead.
- Exemption threshold: If the purchase price is no more than 2,500 euros, the acquisition remains tax-free.
Private buyers should steer clear of elaborate structures intended solely to evade tax: They are legally questionable and generally only worthwhile for very large transactions.
