Enter the property purchase price and click Calculate. You'll instantly see the total stamp duty payable, broken down by band, along with the effective rate and the total cost including stamp duty.
Stamp Duty Land Tax (SDLT) is paid in bands — you only pay each rate on the portion of the price that falls within that band. So on a £375,000 property, you pay 0% on the first £250,000 and 5% only on the remaining £125,000.
Stamp duty must be paid within 14 days of completing your property purchase. Your solicitor or conveyancer usually handles this on your behalf and will include it in their completion statement.
- How much stamp duty on a £300,000 property?
- On £300,000 you pay 0% on the first £250,000 and 5% on the remaining £50,000 — a total of £2,500 stamp duty.
- How much stamp duty on a £500,000 property?
- On £500,000 you pay 0% on the first £250,000 and 5% on the remaining £250,000 — a total of £12,500 stamp duty.
- Is there stamp duty on properties under £250,000?
- No — properties priced at £250,000 or below attract zero stamp duty under the standard 2025/26 rates.
- Does stamp duty apply in Scotland and Wales?
- No. Scotland has Land and Buildings Transaction Tax (LBTT) and Wales has Land Transaction Tax (LTT). This calculator covers England and Northern Ireland only.
- Can stamp duty be added to a mortgage?
- Some lenders allow you to add stamp duty to your mortgage, though this increases your total borrowing and interest paid. Most buyers pay it from savings at completion.
- Do first-time buyers pay stamp duty?
- First-time buyers pay no stamp duty on properties up to £300,000 under the standard first-time buyer relief. On properties between £300,001 and £500,000, first-time buyers pay 5% only on the amount above £300,000. Properties over £500,000 receive no first-time buyer relief. Note: this calculator shows standard rates — first-time buyer relief requires separate calculation.
- Do I pay extra stamp duty on a second home?
- Yes. If you are buying an additional residential property (a second home or buy-to-let), you pay a 3% surcharge on top of the standard rates at every band. This applies even if the additional property is lower in value than your main home.
- When must stamp duty be paid?
- Stamp duty must be paid within 14 days of completing your property purchase. Your solicitor or conveyancer handles this on your behalf and includes it in their completion statement. Missing the deadline can result in penalties and interest.
