IRD report shows wealthy NZers pay much lower tax rates than other earners

Revenue

 Inland Revenue research released today reveals a large differential between the tax rates ordinary New Zealanders pay on their full income compared with the super-wealthy, Revenue Minister David Parker says.

“This internationally ground-breaking research provides hard data showing that the wealthiest New Zealanders pay tax at much less than half the rate of other Kiwis,” David Parker said.

“The data, based on full income information from 311 of our wealthiest citizens, shows that the average person in this group pays an effective tax rate of just 8.9% tax on their economic income – that is, income from all sources, including capital gains on investments.

“In contrast, most New Zealanders pay tax at more than twice that rate. For example, someone earning a salary of $80,000, with no other income, pays 22% tax on that income, excluding GST.

“The difference is mainly because the very wealthy earn only a small portion of their income from wages and salaries, unlike most New Zealanders.

“The differential is even larger when GST is included: for the wealthiest, their effective tax rate rises to 9.5%, but for the person on an $80,000 salary, it goes up to around 28 or 29%. That is because wealthy New Zealanders spend a much smaller portion of their income each year, compared with other earners.”

The High Wealth Individuals Research Project is internationally significant because it uses real data, unlike other overseas studies which draw on surveys or scenarios, David Parker says.

“In 2020, the Government changed the law to enable IRD to require high-wealth individuals to provide their earnings data, in order to do this work,” David Parker says.

“To be clear, this work is not about chasing tax avoiders, nor is it about attacking the rich. Wealthy New Zealanders are usually hard-working and creative people who comply with current rules. They have assisted IRD with this inquiry, and I am grateful for that.

“The excellent work in this survey will enable future discussions on tax policy to be based on solid evidence. Later this year, we intend to introduce a Tax Principles Bill to ensure that information like this continues to be transparently collected and reported on.”

Today’s IRD report release is accompanied by a new Treasury report setting out effective average tax rates across the population. It uses scenarios to show that effective tax rates paid by middle New Zealanders (including GST) are between 6.8 and 10.8 percentage points higher than for the wealthiest people.
