In 2015 George Osbourne announced the phased reduction of tax relief on buy-to-let mortgage interest.
Prior to April 6th 2017 landlords were able to write off 100% of mortgage payments as tax deductions from their rental income. However, since April 6th 2017 landlords have seen the amount they can write off for tax purposes drop by 25%. It will continue to drop a further 25% every tax year until 2020 when landlords will have to declare all their rent as income, pay income tax on the total and then claim 20% back as a credit.

Landlords will have less tax relief and could see their incomes rise for the purposes of declaring income to the tax man.
