BIM80635 - Computing the amount to assess: business changes: succession and changes in ownership: partial changes in ownership

A ‘partial’ change is one where at least one person is engaged in carrying on the trade both before and after the change. The most common examples are a change in membership of a partnership and a sole trader taking on a partner.

On a partial change of ownership, the cessation and commencement provisions do not apply to the persons who are engaged in carrying on the trade both before and after the change (unless exceptionally there is at the same time an actual cessation of one trade and the commencement of a new one). They do apply separately to the individuals who commence or cease to trade.
