At £12,000 gross rent, claim actual expenses rather than the £1,000 Property Allowance — a typical BTL with agent fees, insurance, gas/electrical checks, and repairs easily exceeds that flat deduction. Keep receipts for at least 6 years.
Property Allowance vs actual expenses
HMRC lets you choose the bigger of (a) the £1,000 Property Allowance or (b) your actual allowable expenses. You can't use both on the same property.
| Scenario | Deductible | Taxable profit | Tax |
|---|---|---|---|
| Property Allowance (£1,000 flat) | £1,000 | £11,000 | £2,200 |
| Actual expenses (~20% of rent) | £2,400 | £9,600 | £1,920 |
"Actual expenses" here is an illustrative 20% placeholder — use your own schedule of expenses for a true result.
Basic vs higher-rate taxpayer — 2026-27
| Profile | Other income | Tax | Net cash flow |
|---|---|---|---|
| Basic-rate payer | £30,000 | £2,200 | £8,800 |
| Higher-rate payer | £60,000 | £4,400 | £6,600 |
2025-26 vs 2026-27
Property Allowance (£1,000), income tax bands (20% / 40% / 45%), and Personal Allowance (£12,570) are all unchanged between 2025-26 and 2026-27 for rental income. Under the same basic-rate assumptions, this £12,000 rent produces £2,200 tax in 2025-26 and £2,200 in 2026-27 — identical.
About Section 24 (mortgage interest restriction)
Residential landlords can't deduct mortgage interest as an expense. Instead HMRC gives a 20% tax credit against the interest paid. A higher-rate taxpayer with a heavily-mortgaged BTL can end up paying tax on income they haven't actually earned as cash. If the £12,000 rent in this page is from a mortgaged property, add the interest in the full calculator to see the credit applied.
This page's figures assume no mortgage interest. Incorporation, furnished holiday lets (FHL), and commercial property have different rules.

Frequently asked
How much tax on £12,000 rental income UK?
£2,200 for a basic-rate taxpayer with the £1,000 Property Allowance and no mortgage (2026-27, basic-rate band). A higher-rate payer pays £4,400. Claim actual expenses instead if they exceed £1,000.
Do I declare £12,000 rental income on Self Assessment?
Yes. Gross property income over £1,000 requires declaration. From April 2026, MTD for Income Tax starts phasing in for landlords with combined self-employed + property turnover over £50,000 — quarterly digital updates to HMRC rather than annual SA.
Can I use the £7,500 Rent a Room Scheme instead?
Only if the £12,000 comes from letting a room in your own home. Rent a Room gives a £7,500 tax-free allowance (£3,750 if jointly let). For whole-property BTL, you get the £1,000 Property Allowance or actual expenses — not £7,500.
