Tax
Summary
The ad asks: "Should a teacher pay twice the tax rate of a multi-millionaire?" This reflects a real finding from Inland Revenue's 2023 High-Wealth Individuals Research Project: when tax is measured against broad 'economic income' including unrealised capital gains, the median high-wealth family paid 8.9% in tax, or 9.5% including GST, while Treasury analysis found effective tax rates for many middle-income New Zealanders were at least twice as high. However, this is an effective-tax-rate comparison using a broad economic-income measure, not a comparison of the statutory income-tax rates applied to teachers and wealthy people.
Official research found that, when tax is measured against broad economic income including capital gains, many middle-income New Zealanders paid effective tax rates at least twice those of the high-wealth families studied. The comparison is valid on that measure, but it does not mean teachers literally have a statutory income-tax rate twice as high as multi-millionaires.

What the ad gets right
- +Inland Revenue's High-Wealth Individuals Research Project found the median high-wealth family paid 8.9% of its economic income in personal, company and trustee taxes over 2015 to 2021, rising to 9.5% when GST was included.
- +The official report states that Treasury's accompanying work showed effective tax rates for middle-income New Zealanders were at least double those paid by the high-wealth group on this economic-income basis.
- +The Inland Revenue report specifically listed school teachers among occupations paying substantially higher effective tax rates than the high-wealth families studied.
- +The disparity largely arises because around 80% of the high-wealth group's measured economic income came from capital gains, much of which was not subject to income tax.
What the ad gets wrong or leaves out
- −The phrase "tax rate" is ambiguous. A teacher does not literally face a statutory income-tax rate twice that of a multi-millionaire; New Zealand's personal income-tax rates are progressive and reach 39% above $180,000.
- −The comparison uses an 'effective tax rate' calculated against economic income, which includes unrealised capital gains and other income not normally included in taxable income.
- −On taxable personal income alone, Inland Revenue found the high-wealth group had a median effective income-tax rate of about 30%, so the striking difference depends on including broader economic gains in the denominator.
- −The underlying research covered the 2015 to 2021 period and a selected group of 311 high-wealth families, rather than every multi-millionaire in New Zealand today.
- −The question format presents a fairness judgement to the viewer; whether the difference is appropriate is a policy and values question rather than a factual conclusion.
Detailed Verdict
The ad is grounded in official Inland Revenue and Treasury research showing that middle-income workers, including teachers, can pay effective tax rates at least twice those of very wealthy families when tax is measured against broad economic income. It needs context because this is not a comparison of ordinary statutory income-tax rates and depends heavily on including untaxed capital gains as income.
