Will be receiving the grant every month for next three years into Mexican account from the government for creative activities and the same is tax-free there. Then I transfer the funds into my UK account as I spend mostly in UK and living here only. I have a dual nationality. I have a Spanish nationality, which is how I settled in the UK, and I have a Mexican nationality, which is how I got this fund.
What should be the treatment of the grant from tax point of view? Do I need to report on my self-assessment tax return of the same will be considered as tax-free?
