Declaring foreign interest on Form 2047

Tax 2021 (2020 income)

Hi. New to the forum and to France so I apologise in advance for the naivety of the following questions. I’m fairly familiar with how U.K. tax system works, but didn’t want to presume the same (I know it won’t) will apply to France. We only arrived here on the 16th December 2020. Do we fill in a tax return for the final 2 weeks of 2020 or do the French authorities need to know about income from the whole of 2020? I know the French authorities need to know about global bank accounts held, but I don’t know if international fintech accounts should be put through U.K. tax or French tax after 17/12? Any assistance on nothing tax related and any tips would be greatly appreciated.

There is a helpful pdf attached and page 18 of this pdf shows you what to do.

Enjoy!
