Stamp Duty Guide UK

Understanding SDLT, property tax and additional surcharges in the UK.

Introduction

Stamp Duty Land Tax (SDLT) is a tax paid when purchasing property in England and Northern Ireland. Different rules apply in Scotland (LBTT) and Wales (LTT). Understanding stamp duty is crucial when budgeting for a property purchase.

If you are buying a property, read our Buying Guide to understand the full process and costs involved.

1. What Is Stamp Duty?

Stamp Duty is a tiered tax based on property value. You only pay tax on the portion of the price within each tax band.

Stamp Duty must be paid within 14 days of completion.

2. How Stamp Duty Is Calculated

Stamp duty uses a banded system similar to income tax.

Example (Illustrative):

  • 0% on first threshold
  • 5% on portion above threshold
  • Higher rates apply for higher bands

You do not pay one flat rate on the entire price — only on each portion within its band.

3. First-Time Buyer Relief

First-time buyers may qualify for reduced stamp duty rates if:

  • They have never owned property before
  • The property is below the qualifying price threshold

This can save thousands in upfront costs.

4. Additional Property Surcharge

If you purchase an additional property (buy-to-let or second home), a 3% surcharge is usually added to standard rates.

This significantly increases tax costs for investors — see our Buy-to-Let Guide for investment insights.

5. Non-UK Resident Surcharge

Non-UK residents may be subject to additional stamp duty charges depending on circumstances.

6. Scotland & Wales Differences

Scotland (LBTT)

Land and Buildings Transaction Tax applies instead of SDLT.

Wales (LTT)

Land Transaction Tax replaces SDLT.

Rates and thresholds differ from England.

7. Other Property-Related Taxes

Council Tax

Annual local authority tax paid by occupier.

Capital Gains Tax

8. Budgeting for Stamp Duty

Always include stamp duty in your total purchase budget along with:
