Hi
The original question related to income tax on a French savings account. Article 12 of the tax treaty covers interest and advises that interest arising in France and is owned by a resident of the UK, is only taxable in the UK. (
UK/FRANCE DOUBLE TAXATION CONVENTION ). If the individual is a UK resident, they should request a certificate of residence (
How to apply for a certificate of residence to claim tax relief abroad) which they can use to claim the tax back from the French tax authorities. The UK resident should declare the gross interest in the self assessment tax return, but cannot claim a foreign tax credit, as tax is not payable in France on the interest.
