For each tax year in which a firm—
a
carries on a trade, and
b
has untaxed income or relievable losses from other sources,
each partner's share of the firm's untaxed income or relievable losses other than trading profits or losses is treated, for the purposes of Chapter 15 of Part 2, as profits or losses of a trade carried on by the partner alone (the “notional business”).

A partner starts to carry on a notional business at the later of—
