Enter your plot size and land value to estimate Heidelberg's 2025 property tax — with every step of the maths shown.
Baden-Württemberg rebuilt the property tax (Grundsteuer) for 2025, and the new model surprises a lot of owners: it taxes the land, not the building. Enter your plot size and its land value and this works out the yearly bill — and shows every step, so the number isn't a mystery.
Work out your estimate
Enter your plot size and its land value. Nothing you type is saved or sent anywhere — it stays on your device.
m²
The land area in square metres. If you own a flat, use your share of the plot (your Miteigentumsanteil of the m²), not the whole building's footprint.
€ / m²
The €/m² land value from BORIS-BW. Use the value dated 1 January 2022 — that is the figure the reform is built on. There's a link to look it up below.
Enter your plot size and land value above to see the estimate.
This is an estimate to help you plan, not your bill. The figure that counts comes from your Grundsteuerbescheid from the Stadt Heidelberg — the value is set by the tax office and the rate by the town.
How it works: the land value (plot size × Bodenrichtwert) is multiplied by the Steuermesszahl of 1.3 ‰, which drops by 30 % to 0.91 ‰ for plots used mainly for homes. That gives the Messbetrag, which is then multiplied by Heidelberg's Hebesatz of 185 %. The size, age or type of the house on the plot does not change the bill — only the land counts.
Good to know
What changed in 2025
Germany rebuilt the Grundsteuer after the old property values were ruled unconstitutional. Baden-Württemberg chose a land-value model (modifiziertes Bodenwertmodell): only the plot's area and its land value count, and the building is ignored. Heidelberg reset its Hebesatz to 185 % so the reform raises the same total as before, not more (aufkommensneutral). Because the basis changed, your new bill can be higher or lower than your old one even though the city's total is unchanged — so an old bill is not a reliable guide.
Find your Bodenrichtwert
Use the BORIS-BW 'Grundsteuer B' viewer and read the value dated 1 January 2022 — that is the one the reform uses. The general BORIS map shows other dates, which are not the Grundsteuer figure. The free map lookup is enough; you do not need a paid certificate.
Flats and shared plots
If you own an Eigentumswohnung, the tax is on your share of the land (Miteigentumsanteil), not the whole building. Enter your share of the plot's m² — your purchase deed or the Teilungserklärung gives the fraction.
