Property Transaction Tax Calculator UK (2026/27)
This property transaction tax calculator helps you estimate the upfront tax due when buying a residential property in the UK. It covers Stamp Duty Land Tax for England and Northern Ireland, Land Transaction Tax for Wales, and Land and Buildings Transaction Tax for Scotland.
It is designed for buyers who want a quick estimate before making an offer, comparing regions, or planning their total moving costs.
What this calculator includes
- England and Northern Ireland Stamp Duty Land Tax (SDLT)
- Wales Land Transaction Tax (LTT)
- Scotland Land and Buildings Transaction Tax (LBTT)
- Main residence, first-time buyer and additional property scenarios
- Property price and buyer-type based estimates
- Non-UK resident surcharge where applicable
How it works
Property transaction tax is charged in bands, which means different portions of the purchase price are taxed at different rates. This calculator applies the relevant bands and thresholds for the selected UK region, then totals the amount due based on the buyer type you choose.
If you are buying an additional property or are affected by a regional surcharge, the estimate reflects those higher rates where supported by the selected settings.
Why your result may be different
This calculator provides an estimate for standard residential purchases, but actual tax can differ depending on the transaction details.
- Linked transactions or mixed-use properties
- Reliefs, exemptions or replacement-main-residence rules
- Company purchases or trust ownership
- Leasehold calculations or unusual contract structures
- Changes to rates or thresholds after a tax-year update
Who it’s for
- Home buyers checking likely tax before purchasing
- First-time buyers comparing purchase prices
- Second-home or buy-to-let buyers assessing higher-rate costs
- Anyone budgeting for total upfront moving expenses
