S221 Income Tax (Trading and Other Income) Act 2005
Where the qualifying trade, profession or vocation is carried on in partnership, averaging claims may be made by each individual partner in respect of his or her share of partnership profits. It is not necessary for all of the partners to make a claim.
The partnership profits should therefore be allocated to the individual partners before averaging takes place.
A partnership change does not affect the availability of relief to any individual who was carrying on the trade both before and after the change.
