Buy-to-let landlords - a quick reminder about the expenses you can claim against tax...
Allowable expenses must be wholly and exclusively for the purpose of renting out the property, for example:
📌 General property maintenance and repairs (e.g. fixing a boiler, repainting between tenants)
📌 Utility bills (if paid by you): water, gas, electricity
📌 Insurance (e.g. building, contents and public liability)
📌 Letting agency fees/management fees
📌 Accountant’s fees
This list is not exhaustive!
The area of expenses which causes the most confusion with sole trader landlords is mortgage interest relief. Before April 2020, landlords could deduct mortgage interest from their rental income to reduce their taxable profits. This relief was phased out between 2017 and 2020.
Today, landlords cannot deduct mortgage interest from rental income. Instead, they receive a 20% tax credit on mortgage interest paid.
