Common questions

How is stamp duty calculated on commercial property?
SDLT on non-residential and mixed-use freehold purchases in England and Northern Ireland is charged in slices: 0% on the value up to £150,000, 2% on the portion from £150,001 to £250,000, and 5% on anything above £250,000. Each rate applies only to the part of the price within that band.
What counts as commercial or mixed-use for SDLT?
Commercial (non-residential) property includes shops, offices, warehouses, industrial units, agricultural land and other non-dwelling property. Mixed-use means a single transaction containing both residential and non-residential elements — for example a shop with a flat above. Both use the non-residential rates above.
Does this include leasehold or VAT?
This calculator covers the SDLT on the purchase price (consideration) of a freehold or assigned lease. SDLT on the rent element of a new lease (the net present value charge) is calculated separately and is not included. VAT, if charged, can also affect the SDLT base — check with your solicitor.
Who pays the SDLT and when?
The buyer pays SDLT. An SDLT return must normally be filed and the tax paid to HMRC within 14 days of completion. Your solicitor or conveyancer usually handles this on your behalf.
