Use this calculator to estimate residential Stamp Duty Land Tax (SDLT) for purchases completing in 2025. It includes standard rates, first-time buyer relief, additional property surcharge, and non-UK resident surcharge.
Guidance only. Tax rules can change, and individual circumstances matter. Confirm figures with your solicitor or tax adviser.
How stamp duty works in 2025
Stamp Duty Land Tax is charged in bands, which means each slice of your property price is taxed at a different rate. Many buyers overestimate their bill by applying one rate to the full purchase amount. In reality, the system is progressive, just like income tax bands.
This page focuses on residential SDLT in England and Northern Ireland. If you are buying in Scotland or Wales, different systems apply (LBTT and LTT respectively), and this calculator should not be used for those jurisdictions.
Standard residential SDLT bands used in this calculator (2025)
| Portion of purchase price | Rate |
|---|---|
| £0 to £125,000 | 0% |
| £125,001 to £250,000 | 2% |
| £250,001 to £925,000 | 5% |
| £925,001 to £1,500,000 | 10% |
| Over £1,500,000 | 12% |
First-time buyer relief in 2025
First-time buyers may pay less SDLT if they meet eligibility rules. The calculator applies relief on this basis:
- 0% on the first £300,000
- 5% on the portion from £300,001 to £500,000
- No relief where purchase price is above £500,000 (standard rates apply)
If you select first-time buyer status and enter a price above the qualifying ceiling, the calculator automatically falls back to standard rates and explains why in the result panel.
Additional property and non-resident surcharges
Some buyers pay surcharges on top of standard or first-time buyer rates:
- Additional property surcharge: +5% of the entire purchase price
- Non-UK resident surcharge: +2% of the entire purchase price
These can stack, so a non-UK resident buying an additional property may pay both surcharges in addition to normal SDLT.
Worked examples
Example 1: Standard buyer, £295,000 home
- 0% on £125,000 = £0
- 2% on £125,000 = £2,500
- 5% on £45,000 = £2,250
- Total SDLT = £4,750
Example 2: First-time buyer, £295,000 home
- 0% on full £295,000 under first-time buyer relief
- Total SDLT = £0
Example 3: Additional property, £425,000
- Standard SDLT = £11,250
- Additional property surcharge (5% of £425,000) = £21,250
- Total SDLT = £32,500
Tips for planning your property budget
When buying a property, stamp duty is only one of several up-front costs. A better budget includes:
- Solicitor/conveyancer fees
- Survey and valuation costs
- Mortgage arrangement and broker fees
- Moving costs and immediate repairs
- A contingency reserve for unexpected expenses
Many buyers set aside 1% to 3% of purchase price as a practical cushion beyond deposit and tax.
Frequently asked questions
Is this calculator suitable for Scotland and Wales?
No. Scotland uses LBTT and Wales uses LTT, each with separate bands and rules.
Does first-time buyer relief apply to buy-to-let?
No. Buy-to-let is generally treated as an additional property, so higher rates apply and first-time buyer relief is not available.
Can I rely on this figure for completion?
Use it as an estimate for planning. Your legal representative should confirm the exact amount payable based on your facts and current HMRC guidance.
