What are current England and Northern Ireland SDLT thresholds?

For residential purchases from 1 April 2025, standard SDLT is 0% to £125,000, 2% on the next £125,000, 5% from £250,000 to £925,000, 10% to £1.5 million and 12% above. Eligible first-time buyers pay 0% to £300,000 and 5% up to £500,000; purchases above £500,000 do not qualify. The former £250,000 standard and £425,000 first-time-buyer thresholds are historical.

How much SDLT is due on a £500,000 home?

Under current England/NI residential rates, a standard buyer pays £15,000. An eligible first-time buyer pays £10,000. An additional-property buyer normally pays £40,000 including the 5 percentage-point surcharge, before any non-resident surcharge or special relief. Scotland and Wales have different bands and supplements.

What may change the final bill?

Main-home replacement rules, a possible 2% non-resident SDLT surcharge, lease rent, linked transactions and corporate purchases can change liability. An estimate is not a conveyancer's assessment. SDLT returns and payment are normally due within 14 days of the effective transaction date.

What regional rules and scope are supported?

The engine uses separate date-specific SDLT, Scottish LBTT with Additional Dwelling Supplement, and Welsh LTT main and higher bands. England/NI first-buyer relief is capped by purchase price; Scottish relief has no purchase-price cap, and Wales has no special first-buyer relief. The 2% non-resident supplement applies only to SDLT. Supported effective dates are 6 April 2021 to 5 April 2027. Company purchases, lease rent, mixed-use, linked transactions and transitional contract rules are not supported. Eligibility and refunds are not automatically determined: verify with the relevant authority or your conveyancer.
