In short: A Māori authority is a Māori land trust, incorporation, marae or other eligible Māori organisation that has chosen to be taxed under special rules. It pays income tax at 17.5%. When it pays taxable distributions to its members, it can attach Māori authority credits for the tax it has already paid, and members use those credits in their own tax.

Many Māori land trusts, incorporations and marae pay tax under a separate set of rules built for collectively owned Māori assets. Used well, the rules keep more of the income working for owners and whānau (families). Used carelessly, they can create penalties when distributions are paid. This guide covers who can elect, how the rate and credits work, and what trustees need to file.
Who Can Be a Māori Authority?
Inland Revenue lists the organisations that can elect to be a Māori authority. They include:
trusts and companies under Te Ture Whenua Māori Act 1993, including Ahu Whenua trusts and Māori incorporations, and the Māori Trustee acting for landowners
Māori Trust Boards
mandated iwi (tribal) organisations and their asset-holding companies under the Māori Fisheries Act 2004
trusts and companies that receive and manage Treaty settlement assets for Māori claimants
the Crown Forestry Rental Trust
Marae (communal meeting places) are generally treated as Māori authorities, but can choose to be taxed under the general rules instead.
To elect, the organisation completes Inland Revenue’s Māori authority election form (IR483) and chooses the date it wants the rules to apply from. Inland Revenue confirms the outcome in writing.
What Is the Māori Authority Tax Rate?
A Māori authority pays income tax at 17.5%. For comparison, ordinary trustee income is taxed at 39% (from the 2024–25 income year), and companies pay 28%.
Example: a trust earns $100,000 of taxable income and keeps it. As a Māori authority, the tax is $17,500. Taxed as ordinary trustee income at 39%, it would be $39,000. The real comparison depends on how much is distributed and who receives it, so it’s worth modelling before you elect.
Should Your Trust Elect?
The 17.5% rate is the headline, but it isn’t the whole picture. Weigh up:
Income kept in the trust. If the trust reinvests most of its income in the whenua (land), farm or other assets, the lower rate usually helps most.
Who receives distributions. Credits pass through to members. Members on lower personal tax rates get a refund of the difference, and members on higher rates pay a top-up.
Charitable status. A trust that is a registered charity with an income tax exemption may pay no income tax at all, so it’s a different decision.
Administration. A Māori authority must keep a credit account, report taxable distributions to Inland Revenue every month they’re paid, and file an extra annual return. That needs good records and a clear process.
Getting out later. An authority can leave the rules, but any credit balance is cancelled when it does.
There’s no single right answer. We run the numbers on the trust’s actual income, distribution plans and owners before recommending a path.
How Do Distributions Work?
Distributions to members (owners or beneficiaries), in cash or in kind, are either taxable or non-taxable.
Taxable distributions come from the authority’s taxable income.
Non-taxable distributions come from exempt income or income already taxed under other rules. Some older reserves may also be non-taxable.
The trustees or directors decide which applies, so good records of where each reserve came from matter. Distributions must be shared in proportion: you can’t give taxable amounts to some members and non-taxable amounts to others.
Kaumātua and Education Grants
Kaumātua (elder) grants and education grants are Māori authority distributions too. They can be taxable or non-taxable depending on where the money comes from.
Scholarships and bursaries for study at a school, wānanga (Māori tertiary institution), polytechnic or university are generally exempt income for the student, even when the authority treats them as taxable distributions. To qualify, the payment needs to be for the student’s education and attendance at the institution. Other support doesn’t automatically get this exemption, so check before you pay.
What Are Māori Authority Credits?
Māori authority credits work much like imputation credits on company dividends. They pass the tax the authority has paid through to its members.
The most you can attach is $17.50 of credit for every $82.50 of distribution (a 17.5:82.5 ratio).
The first taxable distribution in a tax year sets the ratio (the benchmark) for the rest of that year. Attaching more than the benchmark can trigger a penalty. Changing it needs a declaration to Inland Revenue (IR407).
The authority keeps a Māori authority credit account (MACA) to track tax paid and credits passed on. The MACA year runs from 1 April to 31 March.
Example: a member receives $82.50 in cash with $17.50 of credits attached, so $100 of taxable income.
On a 10.5% tax rate: tax on $100 is $10.50. The $17.50 credit covers it, and the extra $7.00 is refunded to the member through their tax return.
On 17.5%: tax is $17.50, fully covered by the credit.
On 33%: tax is $33.00. The credit covers $17.50, and the member pays the other $15.50.
What Do Trustees Need to File?
An income tax return (IR8) every year, even if there’s no income, unless a non-active declaration has been filed.
A MACA return (IR8J), due by the same date as the income tax return. Most Māori authorities must file one.
Monthly distribution reporting. Taxable distributions must be reported to Inland Revenue by the 20th of the month after they’re paid, usually online, even if no tax was withheld. The report includes each member’s name, amount, credits and any tax withheld.
Distribution statements to members, so they can complete their own tax.
Provisional tax, under the usual rules, if the authority’s residual income tax is more than $5,000.
Members without an IRD number. If a member hasn’t given their IRD number and the distribution is more than $200, the authority must deduct resident withholding tax at 39%, less any credits attached.
A debit balance in the MACA. If the MACA is in debit at 31 March, further income tax is due by 20 June, plus a 10% penalty. This usually happens when credits attached to distributions exceed the tax paid, so check the MACA before every distribution.
Before You Pay a Distribution: A Checklist
Confirm the trust deed or order allows the distribution, and the trustees have resolved to pay it.
Decide whether it’s taxable or non-taxable, based on where the money comes from.
Check the MACA balance and the benchmark ratio before attaching credits.
Make sure you hold an IRD number for every member being paid, or allow for withholding tax.
Pay the distribution and issue statements to members.
Report it to Inland Revenue by the 20th of the following month.
Other Things to Know
Charities. If the Māori authority is a registered charity with an income tax exemption, the distribution rules above don’t apply.
GST. A Māori authority must register for GST if its taxable turnover is over $60,000 in a 12-month period.
Koha and payments to people. Koha (gifts) and payments for services can have PAYE or GST consequences. Inland Revenue’s guide IR278 covers payments in the Māori community.
Trustee and shareholder changes must be notified to Inland Revenue, with supporting documents from the Māori Land Court.
Donations. A Māori authority can claim a deduction for donations to a Māori association (such as a Māori committee, district Māori council or the New Zealand Māori Council) and for gifts to approved donee organisations, such as kōhanga reo (Māori language preschools). The total deduction is capped at the authority’s net income for the year, before the donation deduction.
Records. Keep tax records for at least seven years.
Leaving the rules. An authority can stop being a Māori authority by writing to Inland Revenue. Any credit balance in its MACA is cancelled at that point, so get advice first.
Common Questions
Is a Māori authority the same as an Ahu Whenua trust? No. An Ahu Whenua trust is a type of trust under Te Ture Whenua Māori Act 1993. It becomes a Māori authority for tax only if it elects to.
What is the Māori authority tax rate? 17.5% of taxable income.
Do members have to pay tax on distributions? Taxable distributions are income for the member. The credits attached count towards the member’s tax, any excess is refunded, and if the credits don’t cover the member’s tax, the member pays the difference. Non-taxable distributions aren’t income for the member.
Should every Māori land trust elect? Not always. It depends on the trust’s income, how much it distributes, its members’ tax rates and whether it has charitable status. It’s worth running the numbers.
What happens if we attach too many credits? The MACA can go into debit, which means further income tax by 20 June plus a 10% penalty. Exceeding the benchmark ratio can also trigger a penalty.
