Tax Payment Due Dates

To give you a starting overview, here are the main dates for small businesses, which typically have a financial year ending 31 March.

End-of-year income tax payment dates

For the year ending 31 March the year before.

7 February if you don’t have a tax agent
7 April if you have a tax agent and a valid time extension

GST payment dates

If you earn less than $500,000 a year you can choose to file monthly, two-monthly or six-monthly.

28th of the month after each of your GST periods ends, except for the period ending 31 March (due 7 May) and the period ending 30 November (due 15 January)

Provisional tax payment dates

These are income tax instalments paid in advance during the year.

7 May, 28 August and 15 January if you file GST returns every month or two months
7 May and 28 October if you file GST returns every six months
The same as the two-monthly GST dates, if you use the ratio method for calculating provisional tax i.e. 7 May, 28 June, 28 August, 28 October, 15 January, 28 February

Fringe benefit tax (FBT) payment dates

The same as your end-of-year tax payment date if you file and pay FBT on an income year basis
31 May, 20 July, 20 October20 Jan if you file and pay FBT quarterly
31 May if you file and pay FBT annually

Employer deduction payment dates

20th of each month if you deduct less than $500,000 total PAYE and ESCT a year
5th and 20th of each month if you deduct more than $500,000 PAYE and ESCT a year

The Inland Revenue website has a table that lets you search, filter and sort key New Zealand tax dates.

For example, if you don’t employ staff and only need income tax (including provisional tax) and GST dates, you can click both those in the filter. You can then sort by ‘soonest first’ to see the results in date order from the date you’re using the table.

Afirmo makes keeping track of your particular tax payment dates easy. One of the free tools provides crucial tax event reminders.

Tax forms and when to file them

Most tax forms can be completed and filed through Inland Revenue’s online service, myIR. Once you’ve registered and have a login, it’s by far the easiest way. Paper-based and downloadable pdf forms are also available if you can’t access myIR for some reason.

End-of-year income tax forms and filing dates

Most businesses file their end-of-year income tax return through myIR. The common online and paper-based forms are:

Sole traders – IR3 individual income tax return, including income from all other sources
Companies – IR4
Partnerships – IR7, plus each partner files an IR3 individual income tax return

For each accounting year ending 31 March, you file your return by:

7 July the same year if you don’t have a tax agent or extension of time
31 March the following year if you have a tax agent and a valid time extension

GST forms and filing dates

Most people file GST returns through myIR. Some accounting software packages will also do this for you. If you don’t have a myIR account Inland Revenue will send you a form.

If you earn less than $500,000 a year you can choose to file monthly, two-monthly or six-monthly. The filing dates are:

28th of the month after each of your GST periods ends, except for the period ending 31 March, which is due 7 May, and the period ending 30 November, which is due 15 January

Provisional tax forms and filing dates

Provisional tax is just income tax paid in advance instalments during the year, so the forms and return filing dates are the same as the end-of-year income tax dates above.

Fringe benefit tax (FBT) forms and filing dates

You can file FBT returns online through myIR. Paper-based forms are also available. They range from IR418 to IR422, depending on whether you file and pay FBT on an income year, quarterly or annual basis.

The FBT filing dates are the same as the FBT payment dates mentioned above, which are:

The same as your end-of-year tax payment date if you file and pay FBT on an income year basis
31 May, 20 July, 20 October and 20 Jan if you file and pay FBT quarterly
31 May if you file and pay FBT annually

Employer deductions forms and filing dates

You file an employment information form – which includes deductions made – for each employee and for every payday. The filing dates are:

If you file online through myIR, within two working days of each employee’s payday
If you file by paper (your annual PAYE and ESCT must be less than $50,000):
- Within 10 working days of each employee’s payday, or
- For paydays between the 1st and 15th of the month, within 10 working day of the 15th; for paydays between the 16th and the end of month, within 10 days of the end of the month

If you file by paper, Inland Revenue will send you these forms:

IR348 – Employment information
IR349 – Employment information (if you have more employees than rows on the IR348)
IR346 – New employee detail
IR344 – Employment information amendments (to correct an IR348 you’ve already filed)

Filing employment information works differently for:

Lump sum payments
Out of cycle payments
Holiday pay paid in advance
Employee share scheme benefits
Schedular payments (taxes deducted and paid to IRD on behalf of contractors)
IR56 taxpayers, such as part-time private domestic workers who are not self-employed but pay their own taxes

The Inland Revenue website has more on these examples of non-standard filing for employment information.

Where to find support and more information

The Inland Revenue website has a huge amount of useful information, but there’s a lot to get your head around, particularly if you’re starting out or stepping up. That’s why it’s important to get professional advice from a business coach, accountant or business lawyer – even if it’s only to get you started on the right footing.

Afirmo makes this easy for small business owners by giving you free tools like set-up wizards, tax registration guides and even crucial tax event reminders. We also have heaps of helpful resources in our learning hub, such as our articles on money and tax and handy tax calculators.
