Q: How much stamp duty will I pay on a £300,000 home?

As a mover, £5,000 : nothing on the first £125,000, 2% (£2,500) on the slice to £250,000 and 5% (£2,500) on the slice to £300,000. As a first-time buyer you pay £0 — the whole price sits inside the £300,000 relief band.

Q: When do I pay stamp duty?

The SDLT return and any payment are due within 14 days of completion (the effective date). Your conveyancer usually files it, but the liability is yours — late filing draws penalties and interest even when the bill itself is £0.

How stamp duty is calculated

SDLT is charged slice by slice, like income tax — not as a single percentage of the price. For a mover buying at £295,000 (GOV.UK's own worked example): nothing on the first £125,000, 2% on the next £125,000 (£2,500) and 5% on the final £45,000 (£2,250), for a total of £4,750. First-time buyers replace the first two bands with a single 0% band to £300,000 and pay 5% up to £500,000 — a £400,000 first home costs £5,000 — but above £500,000 the relief vanishes and standard rates apply to the whole price, so a £500,001 purchase costs about £15,000. Additional properties add 5 percentage points to every band. See the first-time buyer relief guide for who qualifies and the traps that disqualify.
