Estimate Stamp Duty Land Tax

For a straightforward purchase of one residential property in England or Northern Ireland.

Enter the chargeable consideration in whole pounds.

Where is the property?

Scotland uses LBTT and Wales uses LTT, not SDLT.

Which buyer situation applies?

Every joint buyer must meet the first-time-buyer conditions. Higher-rate ownership tests include relevant property worldwide.

Does the SDLT non-UK-resident surcharge apply?

This uses a transaction-specific residence test, not nationality or the general Statutory Residence Test.

Is this a special or uncertain transaction?

Choose yes for a company or trust, shared ownership, lease rent, mixed use, linked purchases, six or more dwellings, a transfer of equity, transitional contract or another relief.

Your purchase price is used only for this calculation. It is not added to a lead record or analytics event.

What this calculator includes and excludes

It estimates SDLT on one straightforward residential purchase or lease premium in England or Northern Ireland using rates effective from 1 April 2025.

It does not determine eligibility, calculate lease rent, complete an SDLT return or cover companies, trusts, shared ownership, linked, mixed-use or multi-dwelling transactions.

How to understand your result

Your result is an estimate for the tax year shown on the calculator. The breakdown lists each step, the rates and thresholds used, and the date the figures were last checked against GOV.UK. Amounts are rounded the way HMRC rounds them where a rule exists.

Each calculator lists what it leaves out, such as other income, reliefs or special cases, so read the assumptions before you rely on the figure. For your own position, check your HMRC online account or speak to a qualified professional.
