An estimate produced by software, not tax advice. England and Northern Ireland only, rates as at April 2025. SDLT depends on facts this calculator does not capture, including linked transactions, reliefs, trusts, partnerships and mixed-use apportionment. A company buying a dwelling for more than £500,000 may pay a flat 17% unless a relief such as the property rental business relief applies; this estimate assumes the relief applies. Have the figure confirmed by the client's conveyancer or a tax adviser.

How stamp duty works on a limited company purchase

A company or SPV buying residential property pays the higher rates: the standard residential bands plus 5% on every band, from the first pound. On a £300,000 purchase that is £20,000 rather than £5,000. If the company is controlled by non-UK residents, a further 2% applies. Purchases of six or more dwellings in a single transaction can be taxed at non-residential rates, which top out at 5%. Multiple Dwellings Relief was abolished for completions on or after 1 June 2024.

Questions brokers ask

What stamp duty does a limited company pay on a buy-to-let?

A company buying a dwelling pays the higher residential rates: the standard bands plus a 5% surcharge on every band. A non-UK resident company pays a further 2%.

Do companies pay 17% stamp duty?

A company buying a dwelling for more than £500,000 can be charged a flat 17%, but reliefs are available, most commonly for a property rental business letting to unconnected tenants. This calculator assumes the relief applies.

Is semi-commercial property cheaper for stamp duty?

Mixed-use property is taxed at non-residential rates: 0% to £150,000, 2% to £250,000 and 5% above. There is no additional-dwelling surcharge on mixed-use purchases.

Can a block of flats be taxed as non-residential?

A purchase of six or more dwellings in one transaction can be treated as non-residential for SDLT, which is often lower than the higher residential rates.

Does this cover Wales or Scotland?

No. Wales has Land Transaction Tax and Scotland has LBTT, which are different taxes. This calculator covers England and Northern Ireland.
