How much SDLT do I pay on a £425,000 property as a mover?

£11,250 of Stamp Duty Land Tax on a £425,000 purchase in England or Northern Ireland for the 2026/27 tax year, treated as a mover (replacement of main home). That works out to an effective rate of 2.65% across the whole purchase price. Standard SDLT bands apply: 0% to £125k, 2% to £250k, 5% to £925k, 10% to £1.5m, 12% above.

Would I save SDLT if I qualified as a first-time buyer?

Yes - a first-time buyer at £425,000 pays £6,250, a saving of £5,000 versus the standard mover rate of £11,250. To qualify, every buyer on the title must have never owned a residential property anywhere in the world.

What if I haven't sold my previous main home yet?

If you complete on the new home before selling the previous one, HMRC treats the purchase as an additional property and charges the +5% surcharge - £32,500 at this price instead of £11,250. You can claim the surcharge back if you sell the previous main home within 36 months of completion on the new one. Most movers either bridge the gap with a short-term loan or accept the surcharge upfront and reclaim it after sale.

SDLT must be paid within 14 days of completion. Your conveyancing solicitor typically files the SDLT return and pays HMRC on your behalf at completion. Build the £11,250 into your completion-day cash budget along with the deposit balance and legal fees.
