KiwiSaver and Tax
Updated for 2026 IRD rates
KiwiSaver Overview
KiwiSaver is a voluntary, work-based savings scheme designed to help New Zealanders save for retirement. It is administered by Inland Revenue, with funds managed by private KiwiSaver providers. Contributions come from employees, employers, and the government. Understanding the tax implications of KiwiSaver is important for managing your overall tax position.
Employee Contributions
As an employee, you choose your KiwiSaver contribution rate. The options are:
- 3% — Minimum employee contribution
- 4%
- 6%
- 8%
- 10%
Your contributions are deducted from your gross (before-tax) pay and are not subject to income tax. They are also not included in your taxable income for the purposes of Working for Families or student loan repayments.
Important: KiwiSaver contributions are deducted from your after-tax earnings for ACC purposes, meaning ACC levies are calculated on your gross pay before KiwiSaver deductions.
Employer Contributions
Employers must contribute at least 3% of your gross salary or wages to your KiwiSaver account. For the 2026 tax year:
- Employer contributions are subject to Employer Superannuation Contribution Tax (ESCT)
- ESCT rates vary from 11.5% to 33% depending on the employee's gross annual earnings from that employer
- Employer contributions are not subject to ACC levies or student loan deductions
- Employer contributions are tax-deductible for the employer
| Employee Gross Annual Earnings | ESCT Rate |
|---|---|
| $0 – $18,500 | 11.5% |
| $18,501 – $53,500 | 18.5% |
| $53,501 and over | 33% |
Member Tax Credits (Government Contribution)
The government contributes up to $521.43 per year to your KiwiSaver account as a member tax credit. This is calculated as 50¢ for every $1 you contribute, up to a maximum government contribution of $521.43 per year. To receive the full member tax credit, you need to contribute at least $1,042.86 to your KiwiSaver account between 1 July and 30 June each year.
PIE Tax on KiwiSaver Funds
KiwiSaver funds are invested through a Portfolio Investment Entity (PIE). This means the investment earnings in your KiwiSaver account are taxed differently from standard investments:
- PIE tax is calculated at your Prescribed Investor Rate (PIR)
- Your PIR is based on your total taxable income from the last 2 years
- PIE tax rates are typically lower than your marginal income tax rate
- The fund manager pays the tax on your behalf — you don't need to include KiwiSaver investment earnings in your personal tax return
Your PIR options are:
- 10.5% — if your total taxable income is $14,000 or less
- 17.5% — if your total taxable income is between $14,001 and $48,000
- 28% — if your total taxable income is over $48,000
If you notify your KiwiSaver provider of the wrong PIR, you may end up with a tax shortfall and be required to pay the difference through your annual tax return.
KiwiSaver and Your Tax Return
Generally, KiwiSaver contributions and investment earnings do not need to be included in your annual tax return. However, you should check:
- If you've been using the wrong PIR, you may need to adjust your tax position
- If you've been over-deducted or under-deducted for ESCT on employer contributions
- If you're making voluntary lump-sum contributions and want to claim the maximum member tax credit
