Commercial stamp duty calculator

Work out an SDLT estimate for a commercial purchase or a new lease. Enter the price or rent schedule to see the separate charges and the assumptions behind them.

England and Northern Ireland. Straightforward commercial purchases and new leases. This tool does not decide a property's tax classification or calculate reliefs and linked transactions.

Planning estimate only. Confirm the tax treatment with your adviser before proceeding with a transaction.

Scope and assumptions

Standard commercial freehold purchases and supported complete-year new leases in England or Northern Ireland. Answer each scope question before calculating.

Assigned leases, mixed-use property and uncertain VAT treatment need a different calculation or review. A nil tax estimate does not itself establish whether a return is needed.

Your transaction

Answer each scope question. Nothing is saved or sent by this calculator. Amounts are in pounds sterling.

Where is the property?What is the transaction?How is the property classified for tax?Is this a single, straightforward transaction?

Confirm there are no linked transactions, special reliefs, connected-party or partnership transfers, uncertain consideration or specialist features.

Effective date of the transaction

Usually completion. Earlier occupation or substantial performance may change this. Supported rules period: 6 April 2026 to 5 April 2027 (2026/27).

Purchase price excluding VAT (£)VAT on the purchase price

Confirm VAT treatment separately. This tool cannot decide an option to tax, exemption or transfer of a going concern. Official VAT rates.

Method and official sources

Rules period: 2026/27. This calculator supports standard commercial freehold purchases and a limited set of new leases. An assigned lease, a mixed-use property or uncertain VAT treatment needs a different calculation or review. A nil tax estimate does not by itself tell you whether a return is needed.

Check the official SDLT reporting guidance. Scotland uses Land and Buildings Transaction Tax; Wales uses Land Transaction Tax.
