A guide to navigating landlord tax responsibilities

IF YOU’RE CONSIDERING BECOMING A LANDLORD or already renting out a property, it’s crucial to understand your current responsibilities. Tax rules related to letting out a home are constantly evolving and can often seem quite complicated to manage on your own.
Any rent you receive, along with nonrefundable deposits or extra payments from tenants for cleaning, repairs, or utility bills, is all considered income. You must officially declare this money to the tax authorities. The same principle applies to any funds kept from a returnable deposit at the end of a tenancy.
Managing Your Tax Brackets
Your rental profits are taxed at the same rates as your regular employment income. Depending on which tax band your total earnings fall into, you will pay 0%, 20%, 40%, or 45%. Since this rental income is combined with your existing earnings, it could potentially push you into a higher tax bracket, which is important to consider if you want a secondary income source.
You must declare your rental income for the relevant tax year, even if the payment is made after the year ends. Fortunately, you can deduct allowable expenses related to work completed during a specific tax year, regardless of whether you settle the final bill before or after the deadline.
Understanding Landlord Tax Relief
Historically, private landlords could deduct mortgage interest payments directly from their rental income before calculating tax. However, a new buy-to-let tax system introduced gradually from 2017 has significantly changed this. Since 2020, landlords can no longer deduct mortgage interest payments from rental income upfront.
Instead of the old deduction, your entire interest payment now qualifies for a flat 20% tax relief. This change means landlords in higher tax brackets may pay significantly more tax than before. Rather than being taxed on rental income minus their annual mortgage costs, they are taxed on a percentage of their total rental income.
Capital Gains and Property Sales
When you decide to sell a buy-to-let property, you will probably face a capital gains tax bill based entirely on the profit you make, not the final sale price. If you have let all or part of the property, a portion of the financial gain remains taxable. Basic-rate taxpayers currently pay 18% on the profit from the sale of a property, while higher- and additional-rate taxpayers pay 28%.
Every individual receives an annual tax-free capital gains allowance, and couples who jointly own assets can combine their allowances to effectively double their tax-free threshold. Anyone making a taxable capital gain from a residential property must submit a residential property return and pay the amount owed within 30 days of completing the sale. Furthermore, if you previously lived in the rental property, you may be able to claim letting relief to substantially reduce your final tax bill.
