From April 2017 the restriction on loan interest as an expense for rental properties owned by individuals, trusts and partnerships began a graduated implementation. In the 2019/20 tax year there is a 25% finance costs deduction against the rental income and 75% is given as a basic rate deduction against tax due. In 2020/21, none of the loan interest will be allowable as an expense against the rental income and all of it will be given as a basic rate deduction against tax due. Companies owning rental property are unaffected by these restrictions.
