French taxe foncière 2026: how to check whether your property tax bill is wrong
In EnglishHow Orka.tax works
A platform founded by two tax lawyers of the Paris Bar, who designed its method. It does not give legal advice and does not represent you: you stay in charge of your claim.
Free simulation
Enter your commune and a few features of your property. In about 60 seconds you get an order of magnitude of what you should be paying. No account, no card.
Complete analysis, €78 incl. VAT per property
We obtain your official assessment sheet (fiche 6675) from the tax administration, rebuild the rental value parameter by parameter and deliver your result: the real amount of your tax, with the claim file ready to submit.
You file the claim
You submit the claim yourself from your impots.gouv.fr personal space, online, from anywhere. You remain the signatory and the administration answers you directly.

Frequently asked questions
Can I use Orka.tax if I live outside France?
Yes. The simulation, the complete analysis and the claim are all handled online. You need your French tax number (numéro fiscal), printed on your taxe foncière bill, to access your impots.gouv.fr space and file the claim. No visit to France and no representative are required.
Is the platform available in English?
The simulator, the platform and the result are in French, because they follow the French tax forms and vocabulary. These guides explain each step in English, and you can write to contact@orka.tax in English.
How much does it cost?
The simulation is free. The complete analysis costs €78 including VAT per residential property, outbuildings such as a garage or a cellar included. There is no subscription and no commission on the refund you obtain.
Which taxes are concerned?
Taxe foncière on residential property. Because the taxe d'habitation on second homes and the new tax on vacant homes are calculated on the same rental value, correcting that value lowers those bills as well.
How far back can a refund go?
A claim filed before 31 December covers the current year and the previous one. When the error is attributable to the administration, up to four more years can be requested, six in total.
