Property purchase tax

How it works

Apply the tax system for the property’s location

Residential property purchases use Stamp Duty Land Tax in England and Northern Ireland, Land and Buildings Transaction Tax in Scotland, and Land Transaction Tax in Wales. Each system has its own bands, reliefs and higher-rate rules.

The main rates are progressive: each rate normally applies only to the part of the price within its band. The calculator shows that band-by-band calculation separately from any whole-price supplement, then adds the amounts to estimate the total tax and effective rate.

The completion or effective date matters because rates can change and transitional rules can apply. The calculator is designed around the current residential rule sets; it is not a complete historical tax calculator.

England, Scotland and Wales

The same purchase price can produce different tax

For a standard £350,000 residential purchase under the current rules, the calculator estimates £7,500 SDLT in England or Northern Ireland, £8,350 LBTT in Scotland, and £7,500 LTT in Wales.

With the default £50,000 deposit and £2,500 entered buying costs, the illustrated cash required is £60,000 in England, Northern Ireland or Wales and £60,850 in Scotland. This cash total is a planning figure: the deposit and buying-cost entries do not change the tax calculation itself.

First-time buyers

Eligibility matters as much as the threshold

For qualifying first-time buyers in England and Northern Ireland, current relief applies to a main-residence purchase costing no more than £500,000. The first £300,000 is charged at 0% and the portion from £300,000 to £500,000 at 5%. On the £350,000 example, that gives estimated SDLT of £2,500.

Scottish first-time buyer relief raises the residential nil-rate threshold from £145,000 to £175,000 and can save up to £600. It reduces the £350,000 example from £8,350 to £7,750. Revenue Scotland states that the relief is unavailable where the Additional Dwelling Supplement applies.

Wales does not provide a general first-time buyer LTT relief, so the calculator does not show that option for Welsh property. Eligibility can depend on every purchaser, previous ownership anywhere in the world, intended occupation and the precise transaction.

Additional property and residency

Higher-rate treatment can materially increase the total

For current England and Northern Ireland transactions, the higher rates for an additional dwelling add five percentage points to each residential band. The £350,000 example therefore produces estimated SDLT of £25,000. A separate 2% non-UK resident surcharge can also apply and can combine with other residential rates.

Scotland’s Additional Dwelling Supplement is currently 8% of the relevant consideration, in addition to ordinary LBTT. On £350,000, the calculator adds £28,000 to standard LBTT, producing £36,350.

Wales uses separate higher residential bands rather than adding one flat supplement. At £350,000, the current higher-rate calculation is £24,950. Replacing a main residence, ownership by another purchaser, previous-property disposal timing and refund rules can all change whether higher rates ultimately apply.

Company purchases

The company option is deliberately limited

Selecting a company purchase applies the ordinary higher residential treatment for the chosen jurisdiction. It does not determine whether a relief or specialist corporate rule applies.

In England and Northern Ireland, certain corporate bodies buying a residential property for more than £500,000 can be charged SDLT at 17% on the whole price, subject to reliefs and exceptions. Annual Tax on Enveloped Dwellings may also need separate consideration. The calculator does not model those rules.

Assumptions and limitations

Confirm the transaction before filing

The estimate assumes a straightforward purchase of one residential property for the entered price. It does not calculate lease rent net present value, linked transactions, shared-ownership elections, mixed-use or non-residential rates, trusts, partnerships, alternative finance, inherited interests, divorce-related exceptions or every available relief.

Historical and transitional rules can depend on contract exchange, substantial performance or another date rather than completion alone. The Scottish ADS change, for example, refers to when the transaction was entered into, while Welsh higher-rate transitional provisions can preserve earlier treatment for some contracts.

The “cash required” result adds the entered deposit, other buying costs and estimated tax. It excludes any costs not entered and does not indicate mortgage affordability. Ask a conveyancer or tax professional to confirm the return and payment deadline for the actual transaction.
