Property purchase

This calculator covers residential property in England and Northern Ireland.

£
First-time buyer relief only applies when all relevant buyers qualify and the property is within the price limit.
The SDLT residence test is specific and may differ from other tax residence tests.

Your estimate

Use the result as a planning guide and change inputs to test the assumptions that matter most.

How this calculator works

SDLT is calculated progressively on portions of the purchase price. First-time buyer relief uses its own bands where the qualifying price limit is met. Additional-property and non-resident surcharges are then added where selected.

How to use it

  1. Enter the residential purchase price.
  2. Select whether you are a standard buyer, first-time buyer or buying an additional property.
  3. Select non-UK resident for SDLT purposes if applicable.
  4. Review the estimated tax and effective rate.

Assumptions and limitations

England and Northern Ireland only. Scotland uses LBTT and Wales uses LTT. Complex transactions, companies, mixed-use property, lease rent NPV and reliefs other than first-time buyer relief are outside this simplified calculator.
