25 per cent. tolerance for changes outside annual review or periodic current income check

23.—(1) This regulation applies where the non-resident parent’s gross weekly income is based on an amount of current income by virtue of regulation 33(2) and, before the next review date, there is a change of circumstances affecting the amount of that current income.

(2) No supersession decision giving effect to that change may be made unless the amount of that current income has changed by at least 25 per cent.

(3) Paragraph (1) does not prevent a supersession decision that—

(a) is made on the Department’s own initiative under regulation 20 or 22;

(b) is made on the ground mentioned in regulation 17(1)(c); or

(c) supersedes a decision determining the non-resident parent’s gross weekly income on the basis of regulation 41.

(4) Where the condition in paragraph (2) is satisfied, the current income (as changed) is to apply even if it does not differ from historic income by an amount that is at least 25 per cent of historic income.
