Using the AIM provisional tax option

The Accounting Income Method (AIM) is a new way of calculating provisional tax for small businesses in New Zealand.

This page covers AIM eligibility and set up. For more information on filing an AIM statement of activity, see Filing an AIM statement of activity.

Businesses choosing to use AIM will make more frequent provisional tax payments based on their actual current earnings rather than calculations on last year's income. This makes AIM a great 'pay as you go' option for growing businesses or businesses with fluctuating, seasonal income.

How does AIM work?

When it comes time to pay provisional tax, MYOB will use AIM to calculate what you owe straight from your categories (chart of accounts) and gather the info into your statement of activity. This is then sent to Inland Revenue.

Note that a statement of activity isn't an income tax return and isn't processed as one. This means if you make a mistake you can simply fix it in the next statement.

AIM eligibility

You first need to check that your business is eligible to use AIM. See the table below for the AIM requirements. If you have any questions, please see the Inland Revenue website or speak with your accountant.

If you...

Setting up AIM in MYOB

After confirming your eligibility, you need to map each category in MYOB to the AIM statement of activity. This is done from within the GST and provisional tax page in MYOB.

Mapping your categories

  1. Go to the Accounting menu and choose Prepare GST return.

  2. Click Get started.

  3. If prompted, enter your MYOB account details (email address and password).

  4. Click AIM settings.


    The AIM settings page lists every field on the AIM statement of activity. You need to map all of your categories to a field.
    Note that not every field will be mapped to a category, but all of your categories must be mapped before lodging your provisional tax return using AIM.

  5. Starting from the topmost field (Gross income from sales and/or services) and working your way down, click +Map category and select all applicable categories for each field.

    If you're unsure about where to map your accounts, please speak with your accounting advisor.

  6. When you've finished mapping your categories, click Save & Exit. You can come back to this page to finish mapping your categories or to map a newly created category.
