Second charge mortgage interest and landlord tax relief

Taking out a second charge mortgage does not automatically create a tax deduction. Relief depends on the use of the money, ownership of the property business and the applicable rules.

Personal borrowing for your own home does not normally qualify for rental-business relief. Obtain tax advice before borrowing or transferring property.

In this easy guide, we’ll cover:

• The tax benefits of a second mortgage.
• The total costs and risks of secured borrowing
• Is a second mortgage tax-deductible?
• What is Landlord Mortgage Interest Tax Relief?
• What to check before seeking a second charge mortgage quotation

A possible tax reduction does not make borrowing affordable. Compare the cost and risks as well as the tax treatment.

What are second mortgage tax benefits?

For individual residential landlords, qualifying finance costs are generally dealt with through a basic-rate tax reduction rather than a full deduction in calculating rental profit. The restriction has applied fully since the 2020 to 2021 tax year.

The purpose of borrowing matters more than which property provides the security. A loan secured on your home may fund a rental business, while borrowing on a rental property may be spent privately. Mixed use can require allocation.

Are second mortgages tax-deductible?

The current rules restrict relief for qualifying finance costs of individuals letting residential property. They do not make every interest payment on every second mortgage eligible, and capital repayments are different from interest. See related guidance.

What is Landlord Mortgage Interest Tax Relief?

Qualifying individual residential landlords normally use a basic-rate tax reduction for relevant finance costs, subject to statutory limits. This is not a social-security tax credit.

The calculation considers qualifying finance costs, property-business profits and adjusted total income. Unused finance costs may be carried forward where allowed. It is not an automatic refund of 20% of every mortgage payment.

What does this mean for higher-rate taxpayers?

Higher-rate taxpayers can qualify for the basic-rate reduction. They are not excluded because of their tax band, but relief may be lower than under the former deduction rules. The result depends on the individual calculation. See related guidance.

How does company ownership differ?

Companies have a different tax regime and are not subject to the same individual residential finance-cost restriction. Operating through a company does not automatically make every borrowing cost deductible.

Incorporating an existing property business requires advice about lending, tax and transaction costs. It is not a simple loophole or a guaranteed way to reduce the overall bill.

Is it worth setting up a property rental business?

Whether company ownership is suitable depends on profits, financing, ownership plans and how money will be taken out. Compare the whole position with a qualified adviser.

There are multiple costs associated with incorporating that can far outweigh any financial gain from being allowed to continue mortgage interest deduction in your taxes. For example:

1. Company borrowing rates, product fees and eligibility can differ from individual landlord products
2. You might need to go through a costly process of switching mortgage
3. You might need to pay additional legal costs
4. Transferring property can trigger property transaction taxes and tax on gains; the rules differ across the UK
5. Corporation Tax and tax on extracting money from the company both matter. Keep records and obtain specialist advice before proceeding. Your property may be repossessed if you do not keep up repayments on borrowing secured against it.
