NB - ACC does not need to be setup when you start a new business. NB - When you submit your first tax return, the IRD sends the information through to ACC who setup an account and send you an invoice based on your earnings. NB - You will receive an invoice every year you are in business (submit a tax return). NB - Businesses receive two invoices, one for shareholders and one for employers. These are calculated based on profit from shares and margin of the return amount you filed.
NB - ACC uses your BIC code to calculate the levies you will need to pay (only if you have earnings liable for ACC levies). Supplying an incorrect BIC code will mean your ACC invoices are calculated incorrectly.
