What is Stamp Duty and who pays it?

SDLT applies to qualifying land and property transactions in England and Northern Ireland. The buyer normally files and pays through their solicitor within the HMRC deadline after completion.

  • Standard rates apply to a single residential property.
  • Eligible first-time buyers can claim relief up to the qualifying price limit.
  • Additional properties usually pay 5 percentage points above standard rates.
  • A non-UK resident surcharge may also apply.

First-time buyer relief and additional property rates

Eligible first-time buyers buying a main residence for no more than £500,000 pay 0% on the first £300,000 and 5% on the remainder. If higher additional-property rates apply, the calculator adds 5 percentage points to the standard residential bands.

England and Northern Ireland only: what is not included

Scotland uses Land and Buildings Transaction Tax and Wales uses Land Transaction Tax. This estimate also excludes the non-UK resident surcharge and specialist rules for companies, trusts, shared ownership, lease rent, mixed-use property and linked purchases.

Frequently asked questions

Is Stamp Duty payable everywhere in the UK?

No. SDLT applies in England and Northern Ireland. Scotland uses LBTT and Wales uses LTT, with different bands and rules.

Do first-time buyers pay Stamp Duty?

Eligible first-time buyers pay no SDLT on the first £300,000 and 5% on the portion up to £500,000. If the price is above £500,000, first-time buyer relief is not available.

Do Buy to Let buyers pay extra Stamp Duty?

A BTL or additional-property purchase will usually attract rates 5 percentage points above the standard bands. Ownership, replacement of a main residence and transaction structure can affect the answer.

When is Stamp Duty paid?

An SDLT return and payment are normally due to HMRC within 14 days of the effective transaction date. A conveyancer usually handles this as part of completion.

Does this calculator cover Scotland or Wales?

No. Use the relevant official LBTT calculator for Scotland or LTT calculator for Wales. Do not use an SDLT result to budget for those jurisdictions.

Can Stamp Duty rules change?

Yes. Thresholds, rates and reliefs can change, sometimes with effect from a specified completion date. Check the current HMRC rules and confirm the final amount with your solicitor.

The Stamp Duty result is an estimate only and is not tax or legal advice. The amount due depends on the full transaction, reliefs, surcharges and the rules in force on the effective date. Confirm the final figure with HMRC or your conveyancer.

"I highly recommend Mariusz Wasiluk (mortgage broker) and Magdalena Kurowska (insurance). We had great communication with them from start to finish. They explained everything clearly, were very helpful, and thanks to them the whole process was much less stressful. Great cooperation!"
