What if you also pay wealth tax in another country?
You can deduct this tax sum from payable IFI
While this will apply to relatively few people, if you have paid wealth tax in another country on certain possessions you own outside France, you can deduct this tax sum from payable IFI up to the amount of French tax that would have been levied on them.
This only applies to French tax residents and to property taken into account in the French IFI calculation.
To calculate the amount deductible fill in Annex 6 of the 2042-IFI.
