How the tax bands work

SDLT is generally calculated progressively: each slice of the price is charged at its applicable rate. Additional-property, residency and company rules can affect the result. The calculator uses the selected treatment and rounds the final charge down to whole pounds. Confirm eligibility and reliefs with your conveyancer.

Rules are shown with the calculation. Read HMRC's residential rates and company purchase guidance.
