First-time buyer relief at £300,000
All £300,000 sits inside the £300,000 zero-rate slice, so a first-time buyer owes £0 and keeps the £5,000 a home mover would pay. Relief needs every buyer on the purchase to be a first-time buyer and the home to be their main residence.
What changes around £300,000
- From £300,000 to £925,000, £625,000 of headroom, every £1,000 more adds £50 for a home mover; the 10% rate starts at £925,001.
- At £350,000 the home-mover bill would be £7,500, £2,500 more than at £300,000.
- At £250,000 the home-mover bill would be £2,500, so the £50,000 step up to £300,000 costs £2,500 in extra stamp duty.
£300,000 is the most a first-time buyer can pay and owe no stamp duty at all. One pound more and the 5% slice starts: at £310,000 a first-time buyer would owe £500. A home mover pays £5,000 here, so relief is worth £5,000, the largest saving it can deliver, and that saving stays fixed all the way up to £500,000.
