- New Zealand’s Green Party proposed a 2.5% wealth tax on net assets exceeding ten million dollars.
- A new 33% inheritance and gift tax would apply to transfers over one million dollars if enacted.
- Corporate and bank profits exceeding one billion dollars would face additional levies up to 2%.
(NEW ZEALAND) — New Zealand’s Green Party on June 21, 2026 proposed a broad tax package that would add a 2.5% wealth tax on net assets above $10 million, a 33% inheritance and gift tax above $1 million, a 2% levy on corporate profits above $1 billion, and a 0.75% levy on bank profits above $1 billion.
The package is not law. It is a party proposal released on June 21, 2026. No effective date, bill text, or enacted transition schedule has been published. That matters for tax year 2026, with returns filed in 2027: current rules remain in place unless Parliament adopts the plan.
The Greens said the package would fund income tax changes aimed at low and middle earners. Those changes include a tax-free threshold for income below $10,000, lower tax for most low and middle earners, and a higher top rate on income above $160,000.
The plan is aimed at high-wealth households and large businesses. It also reaches families planning intergenerational transfers, including gifts made during life and inheritances at death. People with New Zealand assets, or with business interests there, would face the closest exposure if the proposal became law.
Immigrants and visa holders with ties to both New Zealand and the United States would need to track two tax systems at once. The United States does not impose a federal wealth tax. U.S. taxpayers still report worldwide income under IRS rules, and foreign accounts may trigger FBAR or Form 8938 filing. IRS Publication 519 and the IRS international taxpayers portal explain the U.S. side.
The proposal also touches tariff-sensitive sectors indirectly. A higher tax bill on very large corporate profits, or on bank profits, can affect pricing, financing, and capital allocation. No official forecast published with the announcement ties the plan to specific tariff changes or trade measures.
| Tax item | Before June 21, 2026 proposal | After proposal, if enacted |
|---|---|---|
| Wealth tax | No announced annual wealth tax in this package | 2.5% on net assets above $10 million; family home exempt |
| Inheritance and gift tax | No announced tax in this package | 33% on inheritances and gifts above $1 million; exemptions for small gifts, family farms, and family home |
| Corporate profits tax | No extra profits levy in this package | 2% on corporate profits above $1 billion |
| Bank profits tax | No extra bank levy in this package | 0.75% on bank profits above $1 billion |
| Low-income threshold | No new tax-free threshold announced in this package | Income below $10,000 would be tax-free |
| Top income tax rate | Current top-rate settings unchanged by this proposal date | Higher top rate on income above $160,000 |
The wealth tax is the headline item. Under the proposal, only net assets above $10 million would be taxed, and the family home would be excluded. A household with $12 million in net assets, including a protected family home, would face the tax only on the amount above the threshold, subject to the final drafting of valuation and debt rules.
That drafting point is not minor. Wealth taxes usually turn on valuation dates, debt offsets, trust treatment, and rules for jointly held property. None of those mechanics has been released. Anyone with closely held companies, offshore assets, or trust structures would need the final bill before calculating exposure.
⚠️ Warning: This package is a proposal, not enacted law. Do not change 2026 tax filings or asset transfers based on the announcement alone.
The inheritance and gift tax proposal would impose a 33% rate on transfers above $1 million. The Greens said small gifts, family farms, and the family home would be exempt. Those exemptions are broad in concept, but narrow in practice until lawmakers define terms such as “small gifts” and set anti-avoidance rules.
A simple example shows the scale. If a parent transferred $1.5 million in assets and the first $1 million remained exempt, the taxable portion would be $500,000. At 33%, the tax on that excess would be $165,000, assuming no other exemption applied. Final liability would depend on the legislation.
Cross-border families would need extra care. The United States treats gifts and estates under different federal rules. A foreign inheritance can also create U.S. reporting on Form 3520 in some cases. IRS international guidance, including this IRS portal, is the starting point for U.S. filers with overseas transfers.
The proposed taxes on corporate profits and bank profits are narrower. The Greens would apply a 2% levy to corporate profits above $1 billion and a 0.75% levy to bank profits above $1 billion. The threshold means the direct burden would fall on a small group of very large firms.
Large employers, importers, and financial institutions would still examine pass-through effects. Extra taxes on profits can alter dividend policy, retained earnings, borrowing costs, or pricing. Those effects are business judgments, not fixed legal outcomes. No official modeling released with the proposal sets out exact price or tariff-linked effects.
The income tax side works in the opposite direction. Income below $10,000 would be tax-free, and most low and middle earners would receive cuts. Higher earners would face a steeper rate above $160,000. Households near that threshold would need to watch salary packaging, bonus timing, and family trust distributions if the plan advances.
| Group | Potential effect if enacted |
|---|---|
| Households with net assets above $10 million | Annual wealth tax exposure above the threshold |
| Families making large transfers | 33% inheritance and gift tax above $1 million, subject to exemptions |
| Companies with profits above $1 billion | 2% extra profits tax |
| Banks with profits above $1 billion | 0.75% extra bank profits tax |
| Low and middle earners | Lower income tax, including a tax-free threshold below $10,000 |
| Earners above $160,000 | Higher top income tax rate |
No grandfather rule has been published. No transition relief has been published either. That leaves open several practical questions: whether pre-existing trusts would be protected, whether earlier gifts would be counted, and what valuation date would apply for the first year.
📅 Deadline Alert: Watch for any bill introduced after June 21, 2026. If legislation appears before year-end, review estate plans, company structures, and large gifts before December 31, 2026.
People with U.S. tax filing duties should not treat a New Zealand proposal as a U.S. tax event by itself. U.S. residents, including many green card holders and visa holders who meet the substantial presence test, still file under normal IRS rules for tax year 2026. That includes possible FBAR filing if foreign accounts exceed $10,000 in aggregate and possible Form 8938 filing if FATCA thresholds apply. IRS Publication 519 remains the main guide for residency status.
Three steps make sense now. First, identify whether net assets exceed $10 million and whether gifts or inheritances may exceed $1 million. Second, gather valuations, trust deeds, and ownership records. Third, book advice before any large transfer, especially in cross-border families or where U.S. reporting forms such as Form 3520 or FinCEN Form 114 may apply.
Anyone changing residency, moving assets, or making family transfers in tax year 2026 should also keep records that show dates, fair market values, and source of funds. If legislation is introduced, those records will shape both compliance and planning.
