England & NI: Standard Stamp Duty Breakdown
Stamp Duty Land Tax (SDLT) on a £450,000 standard residential purchase is calculated in bands — you only pay each rate on the portion of the price that falls within that band.
| Band | Rate | Tax on this portion |
|---|---|---|
| Up to £125,000 | 0% | £0 |
| £125,001 - £250,000 | 2% | £2,500 |
| £250,001 - £925,000 | 5% | £10,000 |
| Total stamp duty | £12,500 | |
Calculated using published SDLT rates in force since 1 April 2025. Applies to a standard purchase — not a first home or additional property.
First-Time Buyer Relief on a £450,000 House
First-time buyers in England and Northern Ireland pay 0% stamp duty on the first £300,000 of a property, and 5% on the portion between £300,001 and £500,000. On a £450,000 house, that means you pay stamp duty of £7,500 — only the portion of the price above £300,000 is taxed, at 5%. That is a saving of £5,000 compared with the standard rate of £12,500.
To qualify, you (and anyone you are buying with) must never have owned a residential property anywhere in the world before, and the property must be your only or main residence.
Second Home or Buy-to-Let: £35,000
If you already own a residential property and are buying a £450,000 house as an additional property — a second home or a buy-to-let — a 5% surcharge is added on top of every standard band in England and Northern Ireland (raised from 3% on 31 October 2024). That brings the total stamp duty on a £450,000 additional property to £35,000, an extra £22,500 on top of the standard rate.
