Stamp Duty Guide 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.

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
