Hi como,
A certificate of residence is only issued, where you are a UK tax resident and have a foreign income or capital gain.
Where there is no foreign income, but there is a foreign tax implicatiions, we can issue a letter of confirmation of residence.
Where none of these situations apply, you will need to go back to the tax office for the other country to find out what they will accept.
To submit a request for either a certificare of residence or letter of confirmatin of residence, please complete the form here: https://www.gov.uk/guidance/get-a-certificate-of-residence.
