Rental Income Tax Calculator

Working out what you actually owe on rental income means combining your taxable profit, the Section 24 mortgage interest credit, your other income, and - depending where you live - Scottish rates of income tax.

This calculator will bring all of that together into one clear figure, plus a side-by-side view of how your bill changes once the new property income tax rates land in April 2027.

This calculator will let you work out:

✓ Your taxable profit and a full income tax breakdown by band
✓ The Section 24 credit applied to your bill
✓ Your after-tax rental income and effective tax rate
✓ A 2026/27 vs 2027/28 side-by-side comparison

We're building this calculator now - every tool on UK Landlord Tools runs entirely in your browser, with no sign-up required. Join the launch mailing list on the homepage and we'll let you know the moment it's live, along with our other UK landlord calculators and guides.
