About the service
StampDutyCal provides general information and estimated property purchase tax calculations. It is an independent website, not an official government service or a provider of personalised tax advice.
Calculator scope
The SDLT and LTT calculators support straightforward residential freehold purchases by individual buyers in England, Northern Ireland and Wales. The LBTT calculator supports straightforward individual residential purchases in Scotland. All use the stated current rates. It does not establish whether you qualify for relief or whether a surcharge applies.
Companies, trusts, shared ownership, new leases with rent, linked transactions, multiple-dwelling purchases and specialist reliefs need a separate assessment. The property-price-plus-tax figure excludes other buying costs.
Your circumstances
Enter accurate information and confirm the appropriate category. Ask your conveyancer or the relevant tax authority to confirm your final liability and filing obligations. Do not use this calculator to determine an earlier transaction’s tax without checking the applicable historical rules.
Availability and accuracy
We research the published rules and update information when changes occur, but cannot promise that the site will always be available or that every error will be identified immediately. An estimate is not a tax assessment or a submitted return.
Corrections and questions
Please report potential errors to [email protected]. These terms do not seek to exclude rights or responsibilities that cannot lawfully be excluded.
