No double - counting
(1) You cannot count the same amount as * assessable professional income more than once, even if it is described in more than one subsection of section 405 - 20.
Amounts that are partly assessable professional income
(2) If:
(a) you * derive assessable income under or as a result of a * scheme; and
(b) the assessable income consists of a part that is counted as * assessable professional income and another part that cannot be; and
(c) one component is unreasonably large and the other component is unreasonably small, for reasons that are directly or indirectly related to one another;
you must work out your * assessable professional income as if the unreasonably large component were reduced by a reasonable amount and the unreasonably small component were increased by the same amount.
(3) Subsection (2) affects your * assessable professional income:
(a) whether you * derived the assessable income directly or indirectly under or as a result of the * scheme; and
(b) whether or not a reason mentioned in paragraph (2)(c) is the only reason why a component is unreasonably large or small.
