Why purchase a Buy-to-Let using a Limited Company?

There are pros and cons to purchasing a buy-to-let in a limited company versus under a personal name but the choice depends entirely on the individual circumstances of the borrower.

Why purchase a BTL using a limited company?

In 2017, the government set out changes in the Budget, including a reduction in the amount of tax relief available for interest on BTL mortgages, being gradually reduced until only basic rate, 20% is available (by 2021).   This means that landlords will pay tax on their entire rental income and will be unable to deduct the cost of mortgage interest.  Higher rate tax payers will therefore pay a lot more tax and possibly to the point where they make no profit.

This has led to an increase in the number of landlords purchasing BTL investments in a limited company, due to the fact that limited companies pay corporation tax, currently at 19% but reducing to 17% in April 2019.

Differences in lending

As a limited company is a separate legal entity, normally the lenders stress testing is more favourable and they tend to relax this when it comes to rental calculations.  (Usually rental income must cover 125% of mortgage payments, whereas this is 145% when lending is completed in a personal name.)  However, mortgage costs are often higher for a limited company and additional stamp duty costs need to be taken into consideration.

Owners of more than four buy-to-let properties (portfolio landlords) will have to disclose all property details at end of September meaning that the portfolio will be assessed as a whole and if one property performs less well than others this will affect the underwriting of the whole portfolio.
