Tax help for landlords: who we can help
CalculateMyTax helps anyone who earns rent from UK property understand the tax on it. That includes first-time landlords, people letting a room in their own home, joint owners, landlords with a mortgage, landlords in Scotland and landlords approaching Making Tax Digital. The calculator and guides are free and need no sign-up.
Situations we can help with
The tax on your rent depends on how you let, who owns the property and where you live. Find the situation closest to yours below. Each one points to the guide that covers it in detail.
Your first rental property
Property income of £1,000 or less a year, before expenses, does not need to be declared because the property allowance covers it. Above that you must tell HMRC, normally by registering for Self Assessment by 5 October after the tax year ends. The guide to your first landlord tax return covers registering, records and the dates that matter.
Letting a room in your own home
If you let furnished accommodation in the home you live in, Rent a Room relief lets you receive up to £7,500 a year tax free. The guide to the Rent a Room Scheme explains who qualifies, and the calculator compares the relief with claiming your expenses.
Owning property jointly
If you own a rental property with someone else, you pay tax on your own share of the profit, at the rates your own income reaches. Married couples and civil partners who live together are usually taxed in equal shares. Tax on rental income: how much you pay shows how the profit is worked out, and the calculator handles any ownership split.
Landlords with a mortgage
Mortgage interest is not deducted from your rent. Under Section 24 you get a tax credit of 20% of the interest instead, which can leave higher rate taxpayers paying more tax than they expect. The guide to Section 24 mortgage interest relief shows how the credit is limited and how unused interest is carried forward.
Landlords in Scotland
If your main home is in Scotland, your rental profit is taxed at Scottish income tax rates, which use more bands than the rest of the UK. The guide to rental income tax in Scotland sets out the bands and shows where your profit falls.
