Free in Version 1
Can't understand your property tax notice?
The Property Tax Notice Checker recalculates your notice step by step – free and without specialist knowledge.
Version 1 is completely free – all features, no account required.
All 4 calculation models
Federal model, Bavaria, Baden-Württemberg and Hamburg – the app detects your model automatically.
Transparent calculation
Every calculation step is shown with formula and intermediate result. No black box.
Objection draft in minutes
If a discrepancy is found, the app generates a customisable objection draft – recommended: have it reviewed by a lawyer before submitting.
Check your objection deadline
The objection period is only 1 month after the notice is issued (§ 355 AO). When does your deadline expire?
Legal Notice: Grundwächter is an informational checking tool and does not constitute legal advice. Generated objection drafts do not replace advice from a lawyer or tax advisor. The app works based on your inputs – verify all information against your original notice.
