The starting point is whoever has beneficial ownership of the property also has beneficial ownership of the income.
If you are the sole owner of the property and you want to transfer the right of all or part of the income to your wife, then this can be done by a valid declaration or deed of trust without transferring ownership. See the following guidance:
Ownership and income tax
From the date the declaration/deed came into effect, HMRC would expect the income to be reported by reference to the respective beneficial interests. SDLT is dealt with by a different department of HMRC, please follow the contact details below:
