How Stamp Duty is estimated
First-time buyers
Qualifying first-time buyers pay 0% up to £300,000 and 5% from £300,001 to £500,000.
Additional properties
Higher rates are generally 5 percentage points above standard residential rates.
Rates & assumptions
SDLT is marginal: each rate applies only to the part of the property price within that band. Additional-property rates are 5 percentage points above the standard residential rates. A qualifying non-UK-resident residential transaction usually adds a further 2 percentage points to the applicable rates.
| Price band | Standard | Additional property | Non-resident standard* |
|---|---|---|---|
| Up to £125,000 | 0% | 5% | 2% |
| £125,001–£250,000 | 2% | 7% | 4% |
| £250,001–£925,000 | 5% | 10% | 7% |
| £925,001–£1.5m | 10% | 15% | 12% |
| Above £1.5m | 12% | 17% | 14% |
*The 2% non-resident surcharge can also sit on top of additional-property rates. Eligibility and residence tests have exceptions, so check HMRC guidance for unusual transactions.
Worked example: A standard £350,000 purchase gives estimated SDLT of £7,500: £0 on the first £125,000, £2,500 on the next £125,000 and £5,000 on the remaining £100,000.

How this SDLT estimate is built
Stamp Duty Land Tax is calculated marginally, so each percentage applies only to the slice of the purchase price inside that band. The calculator separately models first-time-buyer treatment, the higher rates for additional dwellings and the optional non-UK-resident surcharge; unusual transactions should still be checked against HMRC guidance.
Frequently asked questions
Does this cover Scotland or Wales?
No. Scotland uses Land and Buildings Transaction Tax and Wales uses Land Transaction Tax.
What if a first home costs over £500,000?
First-time buyer relief does not apply and standard residential rates are used.
Is this a substitute for HMRC advice?
No. Special transactions and reliefs can change the amount due, so use it as an estimate.
