SolvedSDLTM33520 | Special provisions relating to partnerships: Transfers of a chargeable interest to a partnership
From HM Revenue & Customs · Stamp Duty Land Tax Manual
If Para10 applies to the transfer of a chargeable interest to a partnership, the chargeable consideration for the transaction is computed as a proportion of the market value - see SDLTM04140 of the chargeable interest transferred.
That proportion is calculated as (100 - SLP)%, where SLP is the ‘sum of the lower proportions’.
Where Para10 applies, the sum of the lower proportions is computed in accordance with the steps set out in Para12 - see SDLTM33550.
