French lawyer requests HMRC letter stating I have a NI number

My French solicitor is asking me to produce a letter from the HMRC to prove that I have a NI.

She sent a template letter called “confirmation of residency and UK liability”.

I called the HMRC on the NI helpline and they have no idea about this letter and won’t type a letter that is not one of their standard letter.

My French sollicitor refuses a P60 as proof.

Does anyone know how to prove to the French authorities I have a valid NI number or what to request from the HMRC?

Hi, do you have an account on the gov.uk site? If so, you can print off a confirmation letter here…

I’d like to help,but it’s not entirely clear from the details why your French lawyer needs proof of your having an NI number, or indeed where you are tax resident.

The title of the lawyer’s template - ‘Confirmation of residency..’ etc probably won’t be proved by having an NI number. Residents and non-residents can both have NI numbers.

Would a certificate of UK tax residence help - IF you’re UK resident?

Can you not show the lawyer copies of your UK tax returns filed as a UK resident?

If you’re French resident, I must admit I can’t work out why you would need to show NI numbers etc. Perhaps a little more information or background on the lawyer’s requirement for either an NI number and/or UK residence status would enable us to help?

Is this for exemption from social charges on capital gains on a house sale? There is a form one can get from HMRC for this .

If you confirm this is what you want then I’ll look it up for you.

Yes that’sto reduce the social charges to 7.5% instead of 17.2%.

I just filled form CA8421 but the first page seems to imply it’s for people working in two countries, however in the middle of it, it asks if I am selling a property abroad (so maybe that’s the right form and the first page is incorrect?)

It"s dual purpose. Not at home rightnow but can look later.
