What is it?

Every company in New Zealand need to maintain an ICA account, basically if you are paying income tax then it is advisable to maintain this correctly as when you start distributing dividend you can also distribute imputation credits to the shareholders.
Imputation credit account is a memorandum account (section OA2), and section OA3 defines an ICA account must record all credits and all debits that arise in the account as at their credit date or debit date.

The credit balance recorded in a memorandum account during a tax year or income year, as applicable, is the excess of credits over debits.
