Starting in April 2017 landlords with residential properties will enjoy less tax relief on their mortgages and other finance costs. This guide explains how the new rules will operate and how landlords can beat the tax increase by increasing or postponing tax deductible expenses, accelerating finance costs, making pension contributions, reducing buy-to-let mortgages, selling properties, investing in other types of property, converting properties to a different use, using alternative investment structures, transferring properties to their spouses/partners, and using a company.
