A balance date is the last day of an accounting year.

For most businesses the accounting year begins on 1 April and ends the following 31 March. When you apply for an IRD number, your balance date will be 31 March. This is called the standard balance date.

The standard balance date might be during your peak season. You can apply to change your balance date.
