UK Residential Stamp Duty Calculator (England & Northern Ireland)
Enter your purchase details to estimate Stamp Duty Land Tax (SDLT). This tool applies progressive tax bands, first-time buyer relief (where eligible), and optional surcharges.
What this stamp duty calculator calculator helps you do
Buying property is expensive, and stamp duty can be one of the biggest upfront costs after your deposit. This calculator helps you estimate that tax quickly so you can plan your cash flow before exchange and completion.
It is designed for residential purchases in England and Northern Ireland, using a progressive system: you only pay each rate on the portion of the price within that band, not one single rate on the full purchase price.
How stamp duty is calculated
SDLT follows a tiered structure. Think of your property price as slices. Each slice is taxed at the rate for its band. The final tax bill is the total of all slices.
Standard residential SDLT bands used in this calculator
| Price band | Rate |
|---|---|
| £0 – £125,000 | 0% |
| £125,001 – £250,000 | 2% |
| £250,001 – £925,000 | 5% |
| £925,001 – £1,500,000 | 10% |
| Over £1,500,000 | 12% |
Reliefs and surcharges included
1) First-time buyer relief
If eligible and the property price is up to £625,000, this calculator applies first-time buyer rates:
- 0% on the first £425,000
- 5% on £425,001 to £625,000
If the purchase price is above £625,000, standard rates apply instead.
2) Additional property surcharge
If this is an additional dwelling (for example, a buy-to-let or second home), an extra 3% is added. In practical terms, this calculator applies that surcharge to the full purchase price.
3) Non-UK resident surcharge
If applicable, a further 2% surcharge can apply. This calculator includes that option so you can stress-test your budget.
Worked examples
Example A: Standard buyer at £350,000
- 0% on first £125,000 = £0
- 2% on next £125,000 = £2,500
- 5% on remaining £100,000 = £5,000
- Total SDLT = £7,500
Example B: First-time buyer at £500,000
- 0% on first £425,000 = £0
- 5% on next £75,000 = £3,750
- Total SDLT = £3,750
Example C: Additional property at £300,000
- Standard SDLT = £5,000
- 3% surcharge on £300,000 = £9,000
- Total SDLT = £14,000
Budgeting tips beyond stamp duty
Stamp duty is only one line item. Build a complete completion budget that also includes:
- Solicitor or conveyancing fees
- Searches and Land Registry fees
- Survey costs
- Mortgage arrangement and valuation fees
- Broker fees (if any)
- Removal and setup costs after moving
A good rule is to keep an extra contingency fund so a small surprise does not derail your move.
Frequently asked questions
Is this calculator exact?
It provides a strong estimate for many normal residential scenarios, but it is not legal or tax advice. Some transactions have special rules, exemptions, or edge-case treatment.
Does this include Scotland or Wales?
No. Scotland uses LBTT and Wales uses LTT, each with different bands and rules. This page is specifically for England and Northern Ireland SDLT.
When is stamp duty paid?
Typically shortly after completion, filed through your solicitor/conveyancer. They usually handle the SDLT return and payment process as part of completion.
Why does the effective tax rate look lower than the top band?
Because SDLT is progressive. Only the top slice is taxed at the top rate; earlier slices are taxed at lower rates or 0%.
