Key Takeaways
- Nauru applies the Employment and Services Tax to employment income and service fees, so foreign-owned businesses hiring locally fall within its payroll scope.
- Special EST rates apply to non-residents, expatriates, and regional processing centre workers, making worker status a key factor for hiring decisions.
- Employers carry registration, withholding, monthly remittance, and recordkeeping obligations, with penalties attaching to payroll tax defaults.
- Reforms to Nauru's payroll taxation remain possible, so investors should monitor the outlook when planning workforce arrangements.
Introduction to the Employment and Services Tax (EST) in Nauru
Payroll tax in Nauru operates through the Employment and Services Tax (EST), a levy on employment income and independent service fees earned from sources within the country. The framework is set out in the Employment and Services Tax Act 2014, with rates fixed by Cabinet Regulation and collected by the Nauru Revenue Office. Although there is no personal income tax statute, the EST functions much like a withholding tax on wages, salaries, and service payments, so the obligation falls on employers and payers rather than on the individuals who receive the money.
This article explains how the EST is structured, who pays it, the applicable rates and thresholds, superannuation obligations that sit alongside it, and the registration, remittance, and recordkeeping duties an employer must meet. It is written for foreign business owners, investors, and their advisers weighing whether to hire staff or engage service providers in Nauru.
Legal Basis: The Employment and Services Tax Act 2014 and Its Amendments
The governing statute is the Employment and Services Tax Act 2014, which commenced on 26 September 2014 following publication in the Gazette. It establishes the charge to tax, while the actual rates sit in a Schedule that can be revised without amending the primary law.
Rate changes are made by Cabinet Regulation under Section 29 of the Act. The most recent confirmed revision, the Employment and Services Tax (Amendment to Schedule) Regulations 2023, was deemed to commence on 1 July 2022 and replaced the earlier Schedule introduced by the 2021 Regulations. Each amending instrument repeals and substitutes the entire rate Schedule rather than editing it in part.
Administrative matters such as registration, returns, and enforcement are not housed in the EST legislation itself. They are dealt with under the Revenue Administration Act 2014, which provides the procedural rules common to the EST, the Business Tax Act 2016, and other taxes. Resident and non-resident status, which determines the applicable rate band, is defined in Sections 3 and 7 of the Act.

What the EST Covers: Employment Income vs. Service Fees Within the Payroll Scope
The tax reaches two streams of income: all employment income, and independent service fee income, in each case where the source is in Nauru. A self-employed individual or a non-resident supplying services in the country is taxed under the service fee component at the same rate that applies to employment income.
One feature distinguishes the EST from a conventional payroll tax. Employer superannuation contributions must be added to the monthly salary, and the tax is calculated on the combined figure of salary plus the employer's contribution.
Because the employer's superannuation contribution is included in the amount subject to EST, the effective payroll cost is higher than the headline salary alone. The combined sum is what determines whether the tax-free threshold is exceeded.
Fringe benefits sit outside the charge entirely; no EST is imposed on them. There is also no value added tax or goods and services tax in Nauru, so the EST stands apart from any consumption tax regime.
EST Rates and the Tax-Free Threshold for Employees
For a resident individual, the structure is a flat rate above a tax-free threshold, with no intermediate progressive bands. The threshold and the rate depend on the pay period, but the rate above the threshold is 20% in each case.
| Pay period | Tax-free band (AUD) | Rate above the band |
|---|---|---|
| Monthly | 0 – 9,240 | 20% |
| Fortnightly | 0 – 4,257 | 20% |
| Weekly | 0 – 2,129 | 20% |
On an annualised basis the threshold is AUD 110,800. Nauruan citizens, persons married to Nauruan citizens, and resettled refugees and asylum seekers are not charged the tax where monthly earnings fall below AUD 9,240.
Some employees are paid on a cycle that is neither monthly, fortnightly, nor weekly. In that situation the employer notifies the Secretary of Finance, who advises in writing the amount to be withheld under Section 17(3).
For completeness, individuals in Nauru face no capital gains, inheritance, or wealth taxes. The EST is the operative charge on labour income.

Special EST Rates: Non-Residents, Expatriates, and Regional Processing Centre Workers
The rate Schedule treats certain non-residents differently from resident employees. Two categories are identified expressly: non-resident individuals engaged in connection with the Regional Processing Centre, and non-resident individuals engaged as expatriate employees by the Republic or a state-owned enterprise.
A specific rate applies to persons working in connection with the Regional Processing Centre, while expatriate employees of the Republic or a state-owned enterprise fall under a separate schedule tiered by annual income. "Regional Processing Centre" carries the meaning given in the Asylum Seekers (Regional Processing Centre) Act 2012, and the definition of a non-resident individual sits in Section 7(3).
The precise tiered figures for these non-resident bands are not reproduced in the publicly retrieved Gazette extracts. If you are budgeting for expatriate or Regional Processing Centre staff, confirm the applicable amounts against the NRO rate schedule before fixing employment terms.
Non-resident persons who supply services other than as employees are taxed through the service fee component, at rates mirroring the employment income rates described above.
Nauru Superannuation Fund: Employer and Employee Contributions on Payroll
Running parallel to the EST is the Nauru Superannuation Scheme, a defined contribution arrangement established under the Nauru Superannuation Act 2019. Both employer and employee contribute a percentage of salary, and the scheme is administered by SuperLife, a New Zealand-based fund manager, on behalf of the Department of Finance.
Contribution rates were originally 5% from each side. The 2025–26 Budget doubled the employer share, and the change took effect on 1 February 2026.
| Party | Contribution |
|---|---|
| Employee | 5% of salary or wages |
| Employer | 10% of salary or wages |
Contributions are mandatory for all employers and employees. A narrow exemption exists for small employers with five or fewer staff, annual turnover below AUD 10,000, and gross assets below AUD 5,000.
The interaction with the EST matters for cost planning. The employer's contribution is folded into the monthly salary figure on which the tax is assessed, although where the combined amount stays under the tax-free threshold, no EST is due. Accumulated balances are generally accessible at retirement age, with limited early-withdrawal conditions, and the superannuation arrangements page sets out the scheme detail. The NRO runs compliance initiatives to confirm that employers are paying correctly and that employees are accumulating their entitlements.

Employer Registration and Withholding Obligations
Before any withholding can occur, an employer or payer must obtain a Tax Identification Number from the Nauru Revenue Office. The NRO is the sole body authorised to issue a TIN, and registration is required under the Revenue Administration Act 2014, the same statute that underpins the EST and the Business Tax.
Companies and self-employed individuals who are resident or conducting business in the country must register with the NRO. Once registered, an employer carries the obligation to withhold EST from qualifying payments and remit it on a monthly basis.
A specific notification duty arises where a resident employee is paid on a non-standard cycle. In that case the employer must notify the Secretary in writing, and the Secretary responds with a written notice setting the amount to be withheld.
Monthly Remittance, Return Forms, and Payment Deadlines
EST is withheld and paid over to the NRO every month. The payment date is the 15th of each month, covering tax withheld in the preceding month.
To illustrate, tax withheld during October must reach the NRO by 15 November. Employers report using Monthly EST Withholding Tax Return forms, and these can be submitted to the NRO by email.
Alongside the monthly cycle, an Annual EST Withholding Tax Summary return is also required. The exact annual filing deadline is not specified in the public material, so confirm the due date directly with the revenue authority when setting your compliance calendar.
Recordkeeping, Compliance, and Penalties for Payroll Tax Defaults
Employers must keep accurate financial records for a minimum of five years. The NRO conducts recordkeeping audits across both small and large businesses to test compliance with the tax laws.
Where obligations go unmet, the NRO issues formal penalty documents, including a Notification of Penalties under EST and a Notice of Penalty Assessment. Failure to meet payroll and superannuation duties can lead to penalties, interest on late contributions, and restrictions on business operations.
The specific statutory penalty amounts and late-payment charges are not set out in the publicly retrieved sources. The penalty provisions sit in the Revenue Administration Act 2014, which is the reference point for the exact figures.
On the international front, Nauru received a "largely compliant" rating from the OECD Global Forum in June 2019 and continues to work toward OECD and EU BEPS Inclusive Framework minimum standards.
What the EST Means for Companies and Investors Hiring in Nauru
For a foreign employer, the payroll arithmetic is straightforward in shape. A resident employee attracts 20% EST on salary above AUD 9,240 per month, plus a 10% employer superannuation contribution on all salary, with that contribution itself counting toward the EST base where the combined amount clears the threshold.
Several local features affect hiring decisions:
- There is no statutory minimum wage in the private sector; pay is set by individual contracts or collective bargaining.
- The Nauru Labour Ordinance fixes a standard workweek of 36 hours for office staff and 40 hours for manual workers, with a minimum employment age of 17.
- Companies and individuals registered locally are not subject to capital gains, inheritance, or wealth taxes.
A point that warrants attention from foreign-owned entities: Nauru has no double taxation agreements. A foreign company cannot invoke treaty relief against EST withholding, although the country has signed the OECD Multilateral Convention on Mutual Administrative Assistance in Tax Matters. Non-resident staff at the Regional Processing Centre or within state-owned enterprises follow the distinct schedules noted earlier.
Outlook: Reforms and Future Changes to Nauru's Payroll Taxation
The clearest recent change is on the superannuation side rather than the tax rate itself. The Nauru Superannuation (Amendment) Act 2025 doubled the employer contribution from 5% to 10% and made contributions mandatory for all employers and employees, effective 1 February 2026.
The EST rate Schedule is reviewed annually through Cabinet Regulation, and the most recently confirmed rates took effect on 1 July 2022. Employers should check the NRO website for any later update, as the rate mechanism allows revision each financial year.
No public proposals point to a change in the flat 20% rate or the tax-free threshold beyond this annual regulatory route. Continued engagement with OECD Global Forum standards and EU minimum standards may, over time, prompt further legislative adjustment, and a broader tax base has been considered though no consumption tax has been introduced.
Conclusion
For a foreign business owner weighing workforce arrangements in Nauru, the classification of each worker as a resident, non-resident, expatriate, or regional processing centre employee is not a procedural detail but the single variable that determines which EST rate applies and therefore the real cost of payroll from day one. Getting that classification right, and maintaining the monthly remittance discipline and records that back it up, is where compliance either holds or breaks.
Because reforms to Nauru's payroll taxation remain possible, a hiring plan built on today's rates and thresholds should be reviewed at regular intervals rather than treated as a fixed input to long-term cost modelling.

Frequently Asked Questions
Yes. While no personal income tax statute exists, the Employment and Services Tax functions as a payroll-style levy on employment income and service fees, collected by the employer or payer. The absence of a personal income tax does not make Nauru a zero-tax jurisdiction for payroll purposes.
The rate is a flat 20% on income above the tax-free band, with no progressive steps. For a monthly pay period the band is AUD 0 to AUD 9,240, equivalent to AUD 110,800 per year, and the threshold scales down for fortnightly and weekly cycles.
It is. The employer's superannuation contribution must be added to the monthly salary, and EST is assessed on the combined figure. From 1 February 2026 the employer contributes 10% and the employee 5%, and where the combined amount falls below the tax-free threshold, no EST is payable.
Withheld tax is paid monthly, by the 15th of the month following the month of withholding. Tax withheld in October, for example, is due by 15 November, reported on a Monthly EST Withholding Tax Return that may be submitted by email.
No. Nauru has not concluded any double taxation agreements, so there is no treaty relief against EST withholding. The country has, however, signed the OECD Multilateral Convention on Mutual Administrative Assistance in Tax Matters, which concerns information exchange rather than rate relief.
Financial records must be retained for at least five years. The Nauru Revenue Office carries out recordkeeping audits on businesses of all sizes, and inadequate records can expose an employer to penalty assessments under the Revenue Administration Act 2014.
