Stamp Duty Guide

Stamp Duty Land Tax (SDLT) is one of the biggest upfront costs when buying a property in England and Northern Ireland. This guide explains how it works, with real examples to help you understand what you'll pay.

What is Stamp Duty?

Stamp Duty Land Tax is a tax you pay when you buy a property or land over a certain price in England and Northern Ireland. Like income tax, it's charged in bands—you pay different rates on different portions of the property price.

Note: Scotland has Land and Buildings Transaction Tax (LBTT), and Wales has Land Transaction Tax (LTT), which have different rates. This guide focuses on SDLT in England.

Current SDLT Rates (2025)

Standard Residential Rates

  • Up to £250,000: 0%
  • £250,001 to £925,000: 5%
  • £925,001 to £1.5 million: 10%
  • Above £1.5 million: 12%

First-Time Buyers

If you're a first-time buyer purchasing a property up to £625,000, you get relief:

  • Up to £425,000: 0%
  • £425,001 to £625,000: 5%

If the property costs more than £625,000, you pay standard rates on the entire amount.

Additional Properties

Buying a second home or buy-to-let? You pay an extra 3% on top of standard rates for each band.

Real Examples: What You'll Actually Pay

Example 1: First-Time Buyer - £200,000 Flat

£200,000 Flat (First-Time Buyer)

Stamp Duty: £0

Why? The property is under £425,000, so first-time buyers pay nothing.

Example 2: Standard Purchase - £350,000 House

£350,000 House (Not First-Time Buyer)

  • First £250,000: 0% = £0
  • Next £100,000 (£250k-£350k): 5% = £5,000

Total Stamp Duty: £5,000

Example 3: Family Home - £500,000 House

£500,000 House

  • First £250,000: 0% = £0
  • Next £675,000 (£250k-£500k): 5% = £12,500

Total Stamp Duty: £12,500

Example 4: Additional Property - £300,000 Buy-to-Let

£300,000 Buy-to-Let (Additional Property)

  • First £250,000: 3% (0% + 3% surcharge) = £7,500
  • Next £50,000 (£250k-£300k): 8% (5% + 3% surcharge) = £4,000

Total Stamp Duty: £11,500

Compare to £2,500 for a main residence at the same price!
