Budget 2025 and Investment Boost
On 22 May 2025, the Government delivered the 2025 Budget, which includes several key tax announcements. Some of the reforms have already been enacted with the passage of the Taxation (Budget Measures) Act 2025. The remaining reforms are expected to be introduced into draft legislation later this year and enacted by 31 March 2026. In some cases, application dates for the reforms could be made retrospective.
Investment Boost
The key tax measure announced in Budget 2025 is “Investment Boost”, which allows an accelerated depreciation deduction of 20% of the tax book value of new assets in the year of acquisition. This change has been enacted and applies for new assets acquired from 22 May 2025.
The 20% upfront deduction reduces the cost base, but ordinary depreciation is claimable for the remaining 80% value, including in the year of acquisition. Claiming Investment Boost is optional, on an asset-by-asset basis.
To be eligible, assets must be brand new, new in use or new to New Zealand. In addition, assets must generally be depreciable for Investment Boost to apply. However, the reform specifically includes commercial and industrial buildings as well as certain other assets and improvements. Residential property and fixed-life intangible property are excluded.
For assets acquired and used in undertaking research and development (R&D) activities, both the 20% deduction and standard depreciation are eligible expenditure under the R&D Tax Incentive, potentially giving businesses an additional cash-flow boost.
Investment Boost is likely to be welcome news to many taxpayers. Various practicalities will need to be worked through, such as how to account for Investment Boost within fixed asset systems. Potential impacts on provisional tax obligations and financial reporting may also need to be considered.
Other Budget measures
Other tax-related aspects of Budget 2025 include:
- Additional funding for Inland Revenue compliance and debt management activity: Additional funding for Inland Revenue is perhaps unsurprising and means the recent trend of increased compliance activity is set to continue. Budget 2025 forecasts show that Inland Revenue is expected to deliver an 8:1 return on investment from audit, compliance review and debt collection activities.
- KiwiSaver reforms: Including increasing the minimum contribution for both employees and employers to 3.5% from 1 April 2026 and 4% from 1 April 2028, and reducing the Government subsidy for most savers.
The Government has also confirmed its intention to progress reforms to the:
- Fringe Benefit Tax (FBT) settings, including for the taxation of motor vehicles: Following earlier consultation, the Government has committed to progressing reforms to address concerns with existing FBT settings and to refocus the FBT system on taxing benefits that are provided as remuneration to employees.
- Thin capitalisation settings: A new consultation proposes changes aimed at boosting foreign direct investment in New Zealand, particularly for infrastructure projects. See further below.
- Taxation of certain employee share schemes for the start-up sector: Further to earlier consultation, the Government has committed to progressing reforms to allow an optional deferral for certain employee share schemes to assist the start-up sector to attract and retain talent.

Consultation on changes to thin capitalisation settings
Budget 2025 confirms the Government’s intention to progress reforms to the thin capitalisation regime.
Consultation is currently open, with feedback sought on whether the current thin capitalisation settings might be discouraging foreign investors from investing in infrastructure projects in New Zealand. Reforms are being considered that could allow additional interest deductions for qualifying projects. In particular, two possible solutions are proposed to address the potential issue:
- A rule targeting infrastructure projects: This rule would allow interest on third-party limited-recourse debt for “eligible infrastructure projects” to be fully deductible (what is meant by “infrastructure” remains to be determined).
- A more general rule focusing on arrangement type: This rule, focusing on the type of arrangement (e.g., third-party debt), is not necessarily limited to infrastructure projects and would apply as an alternative test to existing thin-capitalisation thresholds.
The consultation document is available on Inland Revenue’s Tax Policy website here, with submissions closing on 19 June 2025. It is possible that any resulting changes could be introduced in legislation later this year.
Digital Services Tax Bill not proceeding
The Government has decided not to progress draft legislation that would have introduced a Digital Services Tax (the DST Bill). Broadly, if enacted the DST Bill would have imposed a flat 3% digital services tax on the gross “taxable digital services” revenue of large multinational entities where that revenue was attributable to New Zealand users or New Zealand land (subject to certain criteria and exclusions).
The previous Government introduced the DST Bill in 2023 with an original proposed start date of 1 January 2025 (with legislative flexibility to defer the start date by up to five years to 1 January 2030). The DST Bill was intended to serve as a backstop if an acceptable multilateral solution could not be implemented within a reasonable timeframe.
Following the 2023 General Election, the current Government reinstated the DST Bill, however it remained unenacted before Parliament. On 20 May 2025, Minister of Revenue, Hon Simon Watts, announced in a Beehive release that the Government has been monitoring international developments and has now decided not to progress the DST Bill.

Economic update
Treasury has published the Interim Financial Statements of the Government for the nine months ended 31 March 2025. Key figures include:
- Tax revenue of $89.5 billion, which was $0.2 billion (0.2%) higher than forecast.
- Operating balance before gains and losses (excluding ACC) deficit of $6.6 billion, which was $0.5 billion less than the forecast deficit.
Refer to the Treasury media release here for more information.

Other updates
Other updates include:
- As part of a Beehive release on the KiwiSaver changes in Budget 2025, Minister of Finance Nicola Willis stated that “The Government is working to reduce barriers that may stand in the way of KiwiSaver funds investing in a wider range of New Zealand businesses, assets and infrastructure.” Changes to barriers on how KiwiSaver funds can invest their money could therefore be on the horizon.
- As announced during Budget 2025, consultation has opened on proposals for improving Working for Families (WFF), with the intention of making WFF more accurate and helping to prevent families going into debt. Submissions can be made until 3 July 2025, with the Government discussion document available on Inland Revenue’s Tax Policy website here.
