IHTM27174 - Certification of tax paid: France


Certification of French succession duty paid

Where a double taxation credit is due, you may give a provisional allowance but the case must not be closed until the payment has been certified by the French authorities. The form used for the certification is form No. 50.

If a credit seems appropriate, send two prints of form No. 50 to the parties. Ask them to complete the forms and return both copies to us so that we can send the Forms 50 to France. When you receive the completed form No. 50’s, please send them to TG, for onward transmission to France.

In due course, we will receive a certified form No. 50 back from France. The certified form should be checked carefully, and the necessary credit allowed. If you are uncertain about any aspect of the certified form No. 50, or if you think that the Convention may not have been correctly applied, please refer the case to TG, with a note of your view.


  • The credit given for the French duty cannot exceed the amount of the tax payable here on the property concerned.
Certification of IHT paid

A certificate of IHT paid is given on the French form No. 5180 once the IHT is finalised and paid.

A stock of that form is held TG. It must be completed in triplicate and after completion, must be returned to us.

After checking (it is important that the forms No. 5180 are not marked in any way), they and the file should be sent, with a note of any error or omission, to TG. When the case is closed TG arranges for two copies to be certified and sent, with a schedule of any necessary amendments, to the French authorities. The third copy of the form is retained on our file. The parties do not receive a copy of the certified form, but they should be notified of the despatch of the certificate to France, and a copy of any amendment appended to the form should be sent to them.
