Monthly expenses

Minimising your tax liability

In order to make sure the tax liability on your rental profit is a small as possible, keeping a record of what expenses your rental property has incurred is vital.

There are different rules for what can and can not be claimed for residential properties and we have given a few examples below.

Residential properties

Allowable expenses are things you need to spend money on throughout the day-to-day running of the property, such as:

  • Rents, Rates & Insurance
  • Repairs and Maintenance
  • Loan Interest (abated from 2017-18 reducing to 0% from 2020-21)
  • Legal, Management and Professional fees
  • Cost of Services provided

If you have rented out properties in the past, you may have claimed a 10% wear and tear allowance on your furnished rental property. This has been replaced by a provision for the deduction of expenditure on the replacement of domestic items. Please note however that you will not get relief on the initial cost of furniture or other capital items.

You have to be careful when recording your expenses as some may be of a capital nature, for example initial costs of purchasing the property or building an extension/loft conversion. These types of expenditure are not expense that can be set against your rental income rather the expenses will help reduce any gain if/when you come to sell your rental property.

Furnished holiday lets

If you plan to rent or are renting a furnished holiday let, assuming you meet the qualifying conditions, these rentals are treated as a trade for tax purposes. Furnished holiday lets have certain advantages over other ordinary buy-to-let properties such as 100% of loan interest still being an allowable expense.
