Mortgage payment tax relief

Hi, I currently own a property as tenants in common with my wife and we have submitted a deed of declaration and form 17 to HMRC declaring the beneficial ownership in unequal shares 99:1 in favour of my wife. All rental payments are paid to my wife's account and all mortgage payments go out from her account. What I am trying to understand is how the 20% mortgage interest should be treated for self assessment purposes. The mortgage is held in both of our names but my wife makes all of the monthly payments. I suggest there are two options: 1) As my wife pays 100% of the mortgage payment then she receives 100% of the mortgage interest relief 2) The mortgage interest relief is apportioned as per the 99:1 share in the property - with my wife claims 99% of it and myself 1% Can you please confirm which of the two options are the correct treatment please? Thanks, Mitch

Hi
Thank you for your question.
As you can claim 20% of the mortgage interest against the 20% rental income you will receive.
I have attached guidance for you to consider.
