Stamp Duty Calculator April 2025 – Higher Tax Bills Explained

From 1 April 2025, the Stamp Duty Land Tax (SDLT) thresholds in England and Northern Ireland will revert to levels last seen before September 2022. The change means most home buyers will face higher tax bills, with the nil rate band for standard purchases dropping from £250,000 back to £125,000. First‑time buyers will see their relief threshold fall from £425,000 to £300,000.

The reduction marks the end of temporary measures introduced by the then‑Chancellor Kwasi Kwarteng in the 2022 mini‑budget. Those measures were designed to stimulate the housing market but included a sunset clause that expires on 31 March 2025. No further changes have been confirmed beyond that date, though future budgets could bring additional adjustments.

The effect will be felt most sharply by buyers in lower‑priced brackets and by first‑time purchasers aiming for properties between £300,000 and £425,000. Scotland and Wales, which have devolved property taxes, are not affected by the SDLT reversal.

What are the new stamp duty rates from April 2025?

Key insights

• Most buyers will pay more SDLT after April 2025. A £300,000 home currently attracts no tax for non‑first‑time buyers (thanks to the £250,000 nil rate band); after April the same property will incur £3,500 in tax.
• First‑time buyers face the largest relative increase. The threshold for 0% tax drops by £125,000, meaning a home priced at £400,000 that previously attracted no tax now generates £5,000 in liability.
• Scotland and Wales are entirely unaffected by these changes; they run separate property tax systems (LBTT and LTT respectively).
• Buyers of additional properties (second homes, buy‑to‑let) already pay a 5% surcharge on each band, which was increased from 3% on 31 October 2024 and remains unchanged.
• The temporary measures reversed were originally introduced in September 2022 as a one‑year nil‑rate‑band increase, later extended to 31 March 2025.
• Properties worth more than £500,000 see less relative change because the percentage rates above £125,000 remain the same as before the temporary rise.

Snapshot of key figures

How does the stamp duty calculator work for April 2025?

Using the official GOV.UK SDLT calculator

The official HMRC stamp duty page provides the current rates and allows you to estimate your liability manually. You enter the purchase price, select whether you are a first‑time buyer or buying an additional property, and apply the appropriate bands. The calculator is updated to reflect the post‑April 2025 thresholds.

Example calculation: £295,000 property

Using the GOV.UK example for a standard (non‑first‑time‑buyer) purchase of £295,000 after 1 April 2025, the breakdown is exactly as above. Before April 2025 the same property would have been taxed £0 because the nil rate band extended to £250,000 and the next £45,000 fell into the 2% bracket, yielding £900 – a difference of £3,850.

Differences with third‑party calculators

Several private calculators, such as those offered by MoneyHelper (MACS), CBRE Residential, Knight Frank, HomeOwners Alliance, and StampDutyCalculator.quest, use the same official rate bands. Some add scenarios for first‑time buyers, additional properties, or regional variations. They are convenient but not authoritative; the HMRC portal remains the definitive source for filing and payment.

What are the stamp duty rates for Scotland from April 2025?

LBTT rates and thresholds (unchanged for 2025)

Scotland uses the Land and Buildings Transaction Tax (LBTT), administered by Revenue Scotland. Current rates are: 0% up to £145,000; 2% from £145,001 to £250,000; 5% from £250,001 to £325,000; 10% from £325,001 to £750,000; 12% above £750,000. The additional dwelling supplement (ADS) remains at 6% for second homes and buy‑to‑let properties. The April 2025 SDLT reversal does not affect LBTT. Official rates are available from the Scottish Government LBTT page.

Are the April 2025 changes applicable to Scotland?

No. The SDLT reversal is a UK government policy for England and Northern Ireland. Scotland and Wales have fully devolved property taxes. Anyone buying in Scotland should use a dedicated LBTT calculator and ignore the SDLT headlines. The Welsh Government LTT rates also remain separate, with a nil rate band of £180,000 for standard buyers and £225,000 for first‑time buyers.

When do the April 2025 stamp duty changes take effect and what is reversed?

The key date is 1 April 2025. Below is a timeline of the events leading to this change.

1. 23 September 2022 – The UK Government announces a temporary increase in the SDLT nil rate band to £250,000 and a rise in the first‑time buyer threshold to £425,000, as part of the mini‑budget.
2. 31 March 2025 – The temporary measures expire. From midnight, the nil rate band reverts to £125,000 and the first‑time buyer nil rate band falls to £300,000.
3. 1 April 2025 – The new lower thresholds take effect for all completions in England and Northern Ireland.
4. Future (speculative) – No further changes have been announced for 2026, but the Spring Budget or subsequent fiscal events could introduce new rates.

Impact on average home buyers

For a typical non‑first‑time buyer purchasing a £300,000 home, the tax bill rises from £0 to £3,500 – a significant additional cost. Buyers of properties between £125,000 and £250,000 will now pay 2% on that portion, whereas before they paid nothing. According to ONS house price data, the average UK house price in late 2024 was around £290,000, meaning most buyers will be affected.

Future outlook: stamp duty 2026 and speculation

There is no confirmed legislation for 2026. Some market commentators have speculated about further surcharges on corporate buyers or adjustments to the additional property surcharge, but these remain unconfirmed. Buyers should monitor official HMRC announcements.

What is confirmed and what remains uncertain about the April 2025 stamp duty changes?

Why were the stamp duty thresholds reduced in April 2025?

The temporary higher thresholds were introduced in September 2022 by then‑Chancellor Kwasi Kwarteng as part of a mini‑budget designed to stimulate the housing market during a period of economic uncertainty. The measure was always intended as temporary; legislation included a sunset clause of 31 March 2025. The reversal returns thresholds to the levels that applied before the 2022 mini‑budget. The UK government did not extend the temporary increase in the 2024 Autumn Budget, confirming the sunset would take effect. For buyers, this means higher tax bills, particularly for first‑time buyers purchasing homes between £300,001 and £425,000.

What are the official sources for the stamp duty changes?

HM Revenue & Customs provides the definitive guidance on SDLT. The official HMRC residential property rates page lists the post‑April 2025 bands. The government’s policy paper “The Growth Plan 2022” contains the original announcement.

“From 1 April 2025, the nil rate band for SDLT will revert back to £125,000 for residential properties.”

— HMRC guidance

“The temporary increase to £250,000 was introduced in September 2022 and will end on 31 March 2025.”

— UK Government policy statement

For Scotland, the Scottish Government LBTT rates are the authoritative source, and for Wales, the Welsh Government LTT rates apply.

What is the key takeaway for buyers?

Any property purchase that completes on or after 1 April 2025 will be subject to the lower thresholds. Buyers who can exchange contracts and complete before that date will benefit from the current higher nil rate bands. However, legal timelines must be realistic; rushing a purchase solely to beat the deadline carries risks. Use a reliable mortgage affordability calculator and consult a tax advisor or conveyancer for personalised advice. For first‑time buyers, the first‑time buyer guide: taxes and costs covers the full range of upfront expenses.
