Use this UK Stamp Duty Land Tax (SDLT) calculator to estimate how much stamp duty you may pay when buying a residential property in England or Northern Ireland.
It includes:
- Standard SDLT rates
- First-time buyer relief (where eligible)
- Additional property surcharge (5%)
Enter your purchase price and select the options that apply to you.
Important: This calculator provides an estimate only. It does not cover every scenario (for example: non-UK resident surcharge, mixed-use property, companies, leases, or complex ownership arrangements). SDLT rules can change and your circumstances may affect the outcome. Always confirm figures with a solicitor or tax adviser.
