Stamp Duty Land Tax Calculator (England)
Estimate residential SDLT for purchases in England and Northern Ireland using current post-April 2025 thresholds.
How this English stamp duty calculator works
Stamp Duty Land Tax (SDLT) in England is charged in bands. That means each slice of the purchase price is taxed at a different rate, rather than applying one rate to the full amount. This calculator applies the rates progressively and then adds any relevant surcharges for additional properties and non-UK residents.
The result includes:
- Total estimated SDLT payable
- Effective tax rate (tax as a percentage of price)
- Marginal rate on the highest slice of the purchase
- Band-by-band breakdown so you can see exactly where the number comes from
Current residential SDLT rates in England (from 1 April 2025)
| Portion of property price | Standard rate |
|---|---|
| Up to £125,000 | 0% |
| £125,001 to £250,000 | 2% |
| £250,001 to £925,000 | 5% |
| £925,001 to £1,500,000 | 10% |
| Above £1,500,000 | 12% |
First-time buyer relief
Eligible first-time buyers can pay a reduced amount on purchases up to £500,000:
| Portion of property price | First-time buyer rate |
|---|---|
| Up to £300,000 | 0% |
| £300,001 to £500,000 | 5% |
If the purchase price is above £500,000, first-time buyer relief does not apply and standard rates are used.
Surcharges that may increase your bill
Additional property surcharge
If you are buying an additional residential property (for example, a second home or buy-to-let), a surcharge is usually added to each band. This calculator applies a 5% surcharge where selected.
Non-UK resident surcharge
For buyers treated as non-UK residents under SDLT residence rules, an extra 2% surcharge may apply. This can stack with the additional property surcharge.
Quick examples
- £350,000 standard purchase: SDLT = £7,500
- £425,000 first-time buyer: SDLT = £6,250
- £350,000 additional property: SDLT = £25,000 (standard tax plus surcharge)
Common mistakes people make
- Applying one percentage to the whole property value instead of using tax bands
- Forgetting the additional property surcharge when buying a second home
- Assuming first-time buyer relief still applies above £500,000
- Ignoring residency status for SDLT purposes
Final note
This tool is built for education and planning. Always verify your exact SDLT with your conveyancer or a qualified tax adviser before exchanging contracts, especially where ownership structures, leaseholds, trusts, or relief claims are involved.
