Can I claim mortgage interest as a deduction on my rental property accounts?

I have a portfolio of four rental properties and I want to ensure that I am claiming all relevant expenses against the income. I am a little confused over the changes to the claim of mortgage interest, can I claim this or not?

By Catherine Heinen, FCCA

You’re correct. There have been changes to the ability to claim mortgage interest on rental properties from April 2017. Initially, the costs were restricted to 75%, then 50% and then 25%. From the 2020/21 tax year, only a basic rate deduction was allowable.

This restriction does not affect limited companies who own rental properties, or furnished holiday lets.

The restriction is also known as the 20% tax credit for landlords, and provides 20% tax relief on the lower of:

Total finance costs
Property net profit before the finance costs have been deducted
Adjusted total income

If the lower of the three figures is not finance costs (point 1), the difference will be carried forward. Any unused finance costs will be carried forward and added to the total finance costs for the next tax year.

What other expenses can you claim against your property income?

Here are some examples, the list is not exhaustive.

Agency fees, service charges and ground rent
Insurance
Repairs and maintenance
Mileage to carry out landlord checks
Accountancy fees
Council tax and other utility costs on empty properties

What expenses can’t you claim against your property income?

Capital costs, including enhancements and improvements to the property
Costs that are not wholly and exclusively for the purpose of renting out the property

When determining if repair costs can be included on your tax return, it's important to consider:

What state was the property in when you purchased it? What it in a fit state for renting out, or was some of the work carried out to get it to a fit state?
What type of property you are renting out? Furnished, unfurnished or a Furnished Holiday Let (FHL)?
Are the expenses you have incurred repairs to the building/furniture or improvements or enhancements?
