Stamp Duty first-time buyer relief explained (2026): thresholds, taper and the £500k cliff
First-time buyer (FTB) Stamp Duty Land Tax relief in England and Northern Ireland is a tiered system with a hard upper boundary. Get the price right and a first-time buyer can save up to £10,000 on their SDLT bill versus a standard buyer. Get it wrong by £1 — pay £500,001 instead of £500,000 — and they lose the relief entirely, paying £15,000 instead of £10,000 for the same property.
This is how the relief works in 2026, with the post-1 April 2025 thresholds, worked examples at every common buyer price, and the cliff edge that catches buyers off guard.
The 2026 thresholds at a glance
Since 1 April 2025, FTB relief in England and Northern Ireland uses these bands (HMRC, residential property):
| Slice of price | First-time buyer rate | Standard rate |
|---|---|---|
| £0 – £125,000 | 0% | 0% |
| £125,001 – £250,000 | 0% | 2% |
| £250,001 – £300,000 | 0% | 5% |
| £300,001 – £500,000 | 5% | 5% |
| £500,001+ | No FTB relief — standard rates apply | 5% / 10% / 12% |
Two key boundaries:
- £300,000 nil-rate threshold — pay this or less and a qualifying first-time buyer pays £0 SDLT.
- £500,000 upper limit — buy at exactly £500,000 and you save £5,000 vs a standard buyer. Buy at £500,001 and the relief vanishes; you pay full standard rates from the first pound.
Across England and Wales, 426,474 transactions completed below £300,000 in 2025 — about 53% of all 800,234 sales recorded by HM Land Registry that year. A first-time buyer in that majority paid no SDLT at all.
What changed on 1 April 2025
The thresholds were temporarily raised between September 2022 and 31 March 2025. From 1 April 2025 they reverted to permanent levels:
| Threshold | Before 1 April 2025 | From 1 April 2025 (current) |
|---|---|---|
| FTB nil-rate ceiling | £425,000 | £300,000 |
| FTB upper price cap | £625,000 | £500,000 |
| Standard nil-rate ceiling | £250,000 | £125,000 |
(Source: gov.uk SDLT residential rates page, HMRC.) The changes affected about 60,278 transactions in the £425k-£500k band in 2025 — buyers who completed in that range after 1 April 2025 paid SDLT they would have escaped under the previous regime.
A separate change took effect on 31 October 2024: the additional property surcharge rose from 3% to 5%. That doesn't affect first-time buyers (additional-property is for buy-to-let or second homes), but it's why a single SDLT walk-through in 2026 has to specify the buyer's status.
Worked examples at common price points
These figures use HMRC's published slabs for purchases in England and Northern Ireland from 1 April 2025 onwards. Each example is for a UK-resident buyer purchasing as a single property (not an additional dwelling).
| Purchase price | Standard SDLT | First-time buyer SDLT | FTB saving |
|---|---|---|---|
| £200,000 | £1,500 | £0 | £1,500 |
| £250,000 | £2,500 | £0 | £2,500 |
| £300,000 | £5,000 | £0 | £5,000 |
| £350,000 | £7,500 | £2,500 | £5,000 |
| £400,000 | £10,000 | £5,000 | £5,000 |
| £425,000 | £11,250 | £6,250 | £5,000 |
| £450,000 | £12,500 | £7,500 | £5,000 |
| £475,000 | £13,750 | £8,750 | £5,000 |
| £500,000 | £15,000 | £10,000 | £5,000 |
| £505,000 | £15,250 | No relief — £15,250 | £0 |
| £600,000 | £20,000 | No relief — £20,000 | £0 |
Two patterns are visible:
- Below £300,000, the FTB advantage is full — the buyer pays nothing at all. The relief saves the entire SDLT bill that a standard buyer would owe (£0-£5,000 depending on price).
- Between £300,001 and £500,000, the FTB pays 5% on the slice above £300,000, while the standard buyer pays 5% on the slice above £250,000. The FTB always saves £5,000 across this whole band — exactly the standard buyer's tax on the £250k-£300k slice that the FTB doesn't pay.
Above £500,000 the relief disappears completely.
The £500,000 cliff edge
This is the part of the rule that costs unwary buyers real money:
- At £500,000: FTB pays £10,000. Saving vs standard buyer: £5,000.
- At £500,001: FTB relief is lost. SDLT becomes £15,000.04 — the same as a standard buyer.
So increasing the purchase price by £1 increases the SDLT bill by £5,000.04. There is no taper across this boundary; it's a binary on/off rule.
In practice, the cliff has two effects in the property market: vendors anchor asking prices at exactly £500,000 (rather than £505,000) when an FTB is the most likely buyer, and FTBs negotiate hard to come in at or below the threshold. The same dynamic existed at £625,000 under the pre-April-2025 regime.

Who counts as a first-time buyer?
HMRC's definition is strict. To claim relief, an individual must:
- Have never previously owned a freehold or leasehold (over 21 years) interest in a residential property anywhere in the world.
- Intend to occupy the property as their only or main residence.
- Be purchasing the property alone or jointly only with other first-time buyers (if any joint purchaser has previously owned, the relief is lost for everyone on the title).
- Be buying a freehold or leasehold dwelling in England or Northern Ireland (Scotland uses LBTT; Wales uses LTT — different reliefs apply).
Inheriting a home, owning a property abroad, or being on the title of a parent's buy-to-let all disqualify a buyer from FTB relief in England. There is no exception for a previously-owned share, a divorced ex-spouse's home, or commercial property the buyer once held.
What FTB relief does not cover
A common misconception is that FTB relief eliminates all up-front purchase costs. It does not. SDLT is one line item among nine; the others — conveyancing, searches, survey, insurance, removals, immediate maintenance — apply to every buyer regardless of FTB status. We've broken these down in the 9 hidden costs of buying a house in the UK, and the impact on the all-in monthly bill is in the £200,000 mortgage cost guide.
Buyers in Scotland (Land and Buildings Transaction Tax) and Wales (Land Transaction Tax) operate under separate regimes with different first-time buyer reliefs and different thresholds. Northern Ireland uses the same SDLT system as England.
Refunds and edge cases
A first-time buyer who paid full SDLT but believes they qualified for relief at completion can claim a refund within 12 months of the filing deadline by amending the SDLT return (HMRC SDLT1). Conveyancers handle this routinely.
Buyers using shared ownership face a separate set of rules: SDLT can be paid on the initial share only ("market value election") or on the full market value up front, and the rules for FTB relief on shared ownership were realigned in November 2017. Speak to a conveyancer before completion.
