SDLT on Company inheriting property

An elderly widow owns residential investment properties worth £1m. She has two children. If the children were to form a company which, in due course, inherits their mother’s investment properties would there be an SDLT charge on the properties being transmitted/transferred to the company?
Assuming that the IHT is to be paid by instalments over 10 years it does seem that payment from profits after corporation tax is more affordable than after higher rate income tax.
