If a fund is a designated group investment fund as defined in section OB 1 of the Income Tax Act 2004, it does not need to complete this form. Otherwise, this form must be attached to its income tax return.
If the fund has only category A income, it must file an IR4 (Company income tax return). If it has only category B income, it must file an IR6 (Estate and trust income tax return).
If the fund receives both category A and category B income, an IR4 must be filed.
