Landlords Warned of Potential Tax Bills After Incorporation Advice

Landlords who transferred their property businesses into companies and repaid personal or partnership mortgages with new company borrowing could face unexpected Capital Gains Tax (CGT) bills. This follows a recent First-tier Tribunal judgment highlighting a technical issue with the conventional incorporation process.

For many years, it was common practice for landlords to move mortgaged property portfolios into limited companies by repaying old mortgages with new company loans. This process often involved accountants, tax advisers, solicitors, incorporation providers, and mortgage brokers.

The Tribunal judgment has drawn attention to the difference between a company taking over an existing mortgage and repaying that mortgage with a new company loan. While the financial outcome may appear similar, the legal and tax treatment can differ. If the old mortgage was replaced rather than taken over, HMRC could argue that part of the incorporation was funded with something other than shares, potentially restricting Incorporation Relief and leaving part of the property gain taxable from the date of incorporation.

The Tribunal case involved Property118 and Cotswold Barristers challenging Scheme Reference Numbers imposed by HMRC under the Disclosure of Tax Avoidance Schemes rules. The Tribunal cancelled the Scheme Reference Numbers but did not decide the final tax liability of any individual landlord. The Tribunal noted that the Property118 incorporation model enabled a landlord to obtain Incorporation Relief in full, which “may not be able to obtain if there was a refinancing.”

This finding means advisers can no longer safely assume that repaying old mortgages with new company borrowing is automatically tax-neutral. It does not mean every landlord who refinanced now owes tax, but it highlights the need for careful review.

Transactions may require review where a personally owned or partnership property business was transferred to a company, existing mortgages were repaid at or around the incorporation date, new company borrowing funded those repayments, full Incorporation Relief was claimed, and the professional file does not clearly explain why the new financing qualified for the relevant HMRC treatment. The presence of these features does not prove that tax is payable; contracts, mortgage documents, tax calculations, and movement of money must be examined in each case.

This development is relevant for letting agents and inventory clerks working with landlords who have incorporated property businesses, as it may affect clients’ tax positions and require further professional review.
