Rental income tax basics
How rental income is taxed for UK landlords. What counts, how it interacts with your other income, and how to report it.
What counts as rental income?
Rent is obvious, but deposits, service charges, and tenant payments for damage all have specific rules. Here is what HMRC expects you to declare.
How is rental income taxed?
Rental profit — income minus allowable expenses — is added to your other income and taxed at your marginal Income Tax rate. There is no separate landlord tax rate: the same profit costs a basic-rate taxpayer 20% and a higher-rate taxpayer 40%, which is why the same portfolio can perform very differently in different hands.
All your UK lettings are treated as one property business: profits and losses across properties pool together, and a loss on one flat offsets a profit on another in the same year.
What counts as rental income
Rent itself, plus anything else the tenancy produces: non-refundable deposits and retained deposit deductions, insurance payouts that replace lost rent, and payments for services like cleaning or utilities where you charge for them. Income counts when it is due to you, not when the tenant happens to pay.
Small-scale exceptions exist. Gross property income of £1,000 or less a year is covered by the property allowance and needs no return at all; the Rent a Room scheme gives up to £7,500 tax-free for letting a furnished room in your own home.
When rental income must be reported
You will normally need a Self Assessment return once property profits pass £2,500, or when gross rents pass £10,000 regardless of profit. First-time landlords must register by 5 October after the end of the tax year the letting started — the deadline that catches more new landlords than any other.
Above the MTD threshold, reporting is quarterly through software rather than one annual return. The tax is the same; the rhythm is not.
Losses: worth reporting properly
A rental loss carries forward automatically against future profits of the same property business — but only if it has been reported. Landlords who skip filing in loss-making years surrender relief they will want in profitable ones.
Section 24 makes this sharper: because mortgage interest is a credit rather than an expense, a letting can be cash-negative while still showing a taxable profit. Knowing your actual taxed position mid-year, not next January, is what monthly portfolio reporting is for.
Frequently asked questions
Is rental income taxed differently from salary?
Same Income Tax bands, different National Insurance: rental profits do not carry NI for an individual landlord. The practical difference is Section 24 — mortgage interest gives a basic-rate credit rather than reducing profit, which raises effective rates for leveraged higher-rate taxpayers.
Do I pay tax on the tenant's deposit?
Not while it is simply held and protected — it is the tenant's money. It becomes income only when some of it stops being refundable: deductions you keep at the end of a tenancy count as income at that point.
My rent barely covers the mortgage. Do I still owe tax?
Possibly, yes. Only the interest attracts relief — at 20%, as a credit — and capital repayments are invisible to the calculation. A cash-neutral letting can still produce a taxable profit, which is the Section 24 effect in one sentence.
How is jointly owned rental income split?
Married couples and civil partners default to 50/50 whatever the ownership shares, unless you formally elect to be taxed on actual beneficial ownership. Unmarried joint owners are taxed on their actual shares. The right split can be worth arranging — before the tax year, not after.
