What changed in April 2025?
During the cost-of-living support period, first-time buyers paid zero stamp duty on the first £425,000 of a property purchase (up to a maximum price of £625,000). Those thresholds have now reverted:
| Before April 2025 | Now (2025/26) | |
| FTB nil-rate threshold | £425,000 | £300,000 |
| Max purchase price for FTB relief | £625,000 | £500,000 |
| Rate above threshold | 5% | 5% |
What first-time buyers now pay: worked examples
Here's the stamp duty bill on popular purchase prices, compared to what you would have paid before April 2025:
£300,000 property:
- Stamp duty: £0 (still within the nil-rate band)
- Previously: £0 — no change at this price
£350,000 property:
- Stamp duty: £2,500 (5% on £50,000 above the £300k threshold)
- Previously: £0 — you now pay £2,500 more
£400,000 property:
- Stamp duty: £5,000 (5% on £100,000 above the £300k threshold)
- Previously: £0 — you now pay £5,000 more
£450,000 property:
- Stamp duty: £7,500 (5% on £150,000 above the £300k threshold)
- Previously: £1,250 — you now pay £6,250 more
£500,000 property:
- Stamp duty: £10,000 (5% on £200,000 above the £300k threshold)
- Previously: £3,750 — you now pay £6,250 more
Impact on your total buying costs
For a first-time buyer purchasing a £350,000 home with a 10% deposit (£35,000), the stamp duty adds another £2,500 to your upfront costs. Combined with legal fees (~£1,500) and survey costs (~£500), you're looking at roughly £39,500 needed before you even get the keys.
On a £315,000 mortgage at 4.5% over 25 years, your monthly repayment would be approximately £1,752. You'd need a household income of around £50,000 to comfortably afford this.
How to reduce the hit
- Buy at or below £300,000: You'll still pay zero stamp duty as a first-time buyer
- Negotiate with the seller: In a buyer's market, sellers may accept a lower price to account for the stamp duty increase
- Consider shared ownership: You only pay stamp duty on your share of the property
- Use a Lifetime ISA: The 25% government bonus (up to £1,000/year) can help offset the stamp duty cost
