Dividend and Investment Tax in New Zealand

How does New Zealand tax dividends?

New Zealand operates a dividend imputation system under Part L of the Income Tax Act 2007. When a NZ-resident company pays NZD 28 of corporate income tax at the 28% rate, it credits its Imputation Credit Account (ICA) with NZD 28 and may attach those credits to dividends paid to shareholders. A shareholder receiving a fully imputed dividend of NZD 72 cash grosses up to NZD 100 of assessable income and claims the NZD 28 imputation credit against personal income tax at their marginal rate. The maximum imputation ratio is 28:72 — matching the 28% corporate rate — meaning a company cannot pass on more than NZD 38.88 of credits per NZD 100 of dividend declared. For a 39% top-bracket investor, this leaves NZD 11 of additional tax to pay above the imputation credit. For a 17.5%-bracket investor, the NZD 10.50 excess imputation credit is not refundable to individuals — unlike Australia's franking-credit regime — so it is effectively lost. Resident Withholding Tax (RWT) at 33% applies to the non-imputed portion of any dividend under Section RE 2 of the Act; the paying company withholds and remits this to Inland Revenue before the net cash reaches the shareholder [IRD-DIV].

How is interest income taxed?

Interest earned by NZ residents is subject to Resident Withholding Tax (RWT) under Subpart RE of the Income Tax Act 2007. Savers elect a rate that matches their marginal income tax bracket. The 2025-26 rates, updated for the income tax threshold changes effective 1 April 2025, are: 10.5% on taxable income up to NZD 15,600; 17.5% from NZD 15,601 to NZD 53,500; 30% from NZD 53,501 to NZD 78,100; 33% from NZD 78,101 to NZD 180,000; and 39% above NZD 180,000. Banks and other payers withhold at the elected rate before crediting interest; the default rate where no election is lodged is 33%. For most savers, RWT operates as a final tax on interest income — the gross interest and RWT credit are included in the IR3 return but produce no additional liability when the elected rate matches the marginal rate. Inland Revenue's Smart RWT system now enables financial institutions to apply the correct rate automatically using the saver's IRD records [IRD-RWT].

What is the PIE regime and the 28% PIR cap?

The Portfolio Investment Entity (PIE) regime under Subpart HM of the Income Tax Act 2007 is a managed-fund vehicle that taxes investors at their Prescribed Investor Rate (PIR) rather than their marginal personal rate. Three PIR tiers are available: 10.5%, 17.5%, and 28%. The critical feature is the 28% ceiling — investors earning above NZD 180,000 and facing a 39% marginal rate still pay only 28% PIR on income attributed to them by a PIE. The PIE pays tax on attributed investor income at the fund level, and that income is treated as excluded income under Section CX 56, meaning it is not added to the IR3 and does not inflate the investor's marginal rate calculation. For investors on the 39% rate, the 11-percentage-point saving (39% down to 28%) compounds meaningfully over time. Most KiwiSaver retirement funds are structured as PIEs, making KiwiSaver accumulation subject to the PIR cap throughout the savings lifecycle. If an investor supplies no PIR, the default rate of 28% applies automatically. PIR thresholds are set in Section HM 60 of the Act and are now aligned with the personal income tax thresholds updated from 1 April 2025 [IRD-PIE].

How does the FIF regime tax offshore shares?

The Foreign Investment Fund (FIF) regime under Subpart EX of the Income Tax Act 2007 applies to NZ-resident investors whose attributing interests in offshore entities exceed NZD 50,000 in total cost at any point during the income year. The threshold is based on original purchase price in NZD — not current market value — so a portfolio bought for NZD 48,000 that has grown to NZD 90,000 remains below the threshold; one bought for NZD 55,000 that has fallen to NZD 40,000 still triggers FIF. The default calculation method is the Fair Dividend Rate (FDR): 5% of the opening market value of FIF interests is treated as assessable income for that year, taxed at the investor's marginal rate. Under FDR, actual dividends received and actual capital gains are irrelevant to the taxable income figure — a portfolio that grows 25% or falls 10% both produce 5% of opening value as the taxable amount. The Comparative Value (CV) method is an alternative: taxable income equals the portfolio's closing value plus any dividends and sale proceeds, minus opening value and new purchases. In a down year with no distributions, CV income is zero. Investors may switch between FDR and CV annually. A Revenue Account Method (RAM) was enacted in March 2026, effective from the 2025-26 tax year (1 April 2025), and is available to eligible recent migrants and returning residents. The 2026 Budget, delivered 28 May 2026, proposes raising the individual exemption threshold from NZD 50,000 to NZD 100,000, pending legislation. Direct holdings in companies listed on the Australian Stock Exchange All Ordinaries index that maintain a franking account are generally exempt from FIF; dividends from those shares remain taxable at marginal rates but without the FIF overlay. NZ-domiciled PIE funds that invest offshore are also exempt from FIF at the investor level — the PIE itself handles the tax, capped at 28% PIR [IRD-FIF].

Is there a capital gains tax on investments in New Zealand?

New Zealand does not have a general capital gains tax. Gains made on the sale of most NZ and Australian shares, property held outside the bright-line period, and the vast majority of financial assets are not taxable as capital gains. The bright-line test applies to residential property: sales within ten years of acquisition (reduced to two years for new builds and land) trigger income tax on the gain at the seller's marginal rate. For share investors, the absence of a CGT means that growth in a domestic portfolio value above the FIF threshold is not subject to tax — only the 5% FDR deemed income on the opening portfolio value is assessable. Non-residents investing in NZ shares are subject to Non-Resident Withholding Tax (NRWT): dividends face 30% NRWT on non-imputed amounts and 0% on fully imputed dividends — a feature unique to NZ where the corporate-level imputation extinguishes NRWT entirely; interest faces 15% NRWT (or a 2% Approved Issuer Levy paid by the borrower in lieu); royalties face 15%, reducible by double tax agreement to 10% or 5% [IRD-CGT].
