Intro

Use this commercial stamp duty calculator to estimate UK non-residential property purchase tax. It covers SDLT in England and Northern Ireland, LBTT in Scotland, and LTT in Wales using commercial property bands checked against official sources on 20 May 2026.

What this commercial stamp duty calculator does

The calculator estimates tax from:

  • Commercial or mixed-use property price.
  • Property location.

It then shows the estimated tax, effective rate, total cost including tax, and a band-by-band breakdown.

How it works

Commercial property transaction tax is charged in slices. Each part of the purchase price is taxed at the rate for that band rather than one rate being applied to the full price.

For England and Northern Ireland, the calculator uses non-residential SDLT bands. For Scotland, it uses non-residential LBTT bands. For Wales, it uses non-residential LTT bands.

Example calculation

For a 275,000 commercial property in England or Northern Ireland, the calculator applies:

  • 0% on the first 150,000.
  • 2% on the portion from 150,001 to 250,000.
  • 5% on the portion from 250,001 to 275,000.

The result is an estimated SDLT bill of 3,250.

How to use the result

Use the estimate when comparing purchase prices, planning cash required on completion, or checking a solicitor's early estimate. For a wider purchase budget, compare it with the Commercial Lease Stamp Duty Calculator and Moving Costs Calculator.

Assumptions and limitations

  • The calculator is for commercial, non-residential, or mixed-use purchase estimates.
  • It can also approximate tax on a lease premium, but it does not calculate rent NPV; use the lease calculator for that.
  • It excludes linked transactions, reliefs, transitional rules, multiple purchases, companies-specific advice, VAT, legal fees, and filing deadlines.
  • Tax rules can change, and the effective date of the transaction matters.
  • Confirm the final figure with a solicitor, accountant, or the relevant official calculator before completion.

FAQs

  • Is this the same as residential stamp duty? No. Commercial and mixed-use property normally use non-residential bands, which differ from residential bands.
  • Does this cover Scotland and Wales? Yes. Choose Scotland for LBTT or Wales for LTT.
  • Does this include lease rent tax? No. Use the separate commercial lease stamp duty calculator for rent NPV.
