InputValue
Purchase price£295,000
Buyer typeMoving home, not first-time buyer
SDLT due£4,750

A £295,000 mover pays £4,750: 0% on the first £125,000, 2% on the next £125,000 (£2,500), and 5% on the remaining £45,000 (£2,250).

Relief is 0% to £300,000 and 5% on the next £200,000. Above £500,000 the relief is lost entirely and standard bands apply.

Method & assumptionsAuthoritative sources

This calculator applies the residential Stamp Duty Land Tax (SDLT) bands in force in England and Northern Ireland from 1 April 2025. SDLT is charged in slices. It includes first-time buyer relief and the 5% higher rates for an additional property, but it does not combine those mutually exclusive treatments.

It does not model the separate 2% non-UK resident surcharge, purchases by companies, linked transactions, mixed-use property or other specialist rules. Scotland and Wales use LBTT and LTT instead. Verify your position with HMRC and your conveyancer before exchange.

Common mistakes

  • !Comparing rent and ownership costs without including taxes, fees and maintenance.
  • !Using purchase price alone without testing financing or vacancy assumptions.
  • !Relying on yield or growth in isolation instead of reviewing the full property case.
  • !Using the wrong national transaction-tax calculator for the purchase location.

What to do next

  • Confirm which buyer status applies, especially if anyone in the purchase already owns residential property.
  • If the property is in Scotland or Wales, switch to the LBTT or LTT calculator instead of using these England and NI bands.
  • Verify the final liability with the conveyancer and current HMRC guidance before exchange or completion.
