So, a declaration of Trust saying we are transferring 100% of rental income to 1 of 4 joint tenants is sufficient?

We own a property that myself (father), wife and 2 adult children are 'joint tenants' owners on the land registry (not tenants in common) We are transferring 100% of the rental income to one of 4 owners. From going through the forum replies so far, it seems it is not suitable for us to complete Form 17. That signed Declaration of Trust by all the joint tenants declaring that we are transferring 100% of the rental income to one person would suffice for tax purpose. Am I correct?
