Key Takeaways
- Nauru has no conventional income tax; individual income is instead charged through the Employment and Services Tax (EST).
- Liability under the EST turns on residence status and the source of an individual's income, affecting both residents and non-residents.
- Employment income, termination payments, allowances and self-employment service fees fall within the EST, while certain income remains outside the charge.
- Individuals face withholding and monthly payment obligations, and the regime carries specific implications for expatriates, employees and investors.
Understanding Personal Income Tax in Nauru: The Employment and Services Tax (EST)
Nauru does not run a broad personal income tax of the kind found in larger economies. What it does levy is the Employment and Services Tax (EST), introduced by the Employment and Services Tax Act 2014, which charges tax on employment income and on fees earned by independent service providers from sources in Nauru.
The EST is the closest instrument the country has to a personal income tax, and there is no separately titled income tax act for individuals. It reaches anyone earning employment or service-fee income with a Nauru source, including expatriate staff and non-resident contractors. You can confirm the governing statute and its amendments through the Nauru Revenue Office legislation page.
This article explains how the EST applies to individuals: who is liable, the rates and thresholds, how employment and self-employment income are treated, filing duties, and what the regime means for foreign employees and investors. It is most relevant to expatriates taking up work in Nauru, foreign-owned businesses employing staff there, and advisers assessing exposure for non-resident clients.
Legal Basis: The Employment and Services Tax Act 2014 and Why Nauru Has No Conventional Income Tax
Three statutes frame individual taxation. The Employment and Services Tax Act 2014 imposes the EST and defines who counts as a resident and non-resident; the Revenue Administration Act 2014 sets the rules for assessment, collection, enforcement, and Tax Identification Number registration; and the Business Tax Act 2016 deals with business profits rather than personal earnings.
The country imposed an income-type tax for the first time on 1 October 2014, initially a flat 10% on higher earners. Regulatory amendments under the Act have since lifted the top rate, with Cabinet empowered to amend the rate Schedule by Regulation.
Two such amendments matter for the rate tables. One was gazetted in March 2021 (GN No. 122/2021); another, deemed to have commenced on 1 July 2022, was gazetted in 2023 (GN No. 179/2023).
Before 2014, the jurisdiction was regarded as a tax haven, owing to an international financial centre that offered offshore banking. The EST marked a clear break from that zero-tax history.
Several familiar taxes remain absent. There is no capital gains tax, no conventional corporate income tax on profits, and no wage tax operating as a standalone levy outside the EST framework.

Who Is Liable: Residents, Non-Residents, and the Source of Individual Income
Liability turns on the source of the income and on whether you are a resident or non-resident person, as those terms are defined in the Act. Non-resident individuals are generally taxed only on income derived from sources within the country.
For residents, the scope is set by the statutory residence definitions and the detailed rules in the Act and its explanatory memorandum. Note one point that often surprises foreign workers: holding Nauruan citizenship, or the right to reside, does not by itself make you a tax resident.
A contrast with business taxation is worth flagging. The Business Tax Act was amended from 1 January 2021 to tax the foreign income of resident persons, moving that regime to a worldwide basis.
The EST has not been amended to follow the business-tax shift to worldwide income. Its charge on individuals remains tied to Nauru-source employment and service-fee income.
Residency tests are addressed in full in our separate residency article and are touched on here only where unavoidable.
EST Rates and Bands: The Tax-Free Threshold and the 20% Rate on Employment Income
The headline structure for protected residents is a generous exemption topped by a flat upper rate. Nauruan citizens, persons married to Nauruan citizens, and resettled refugees and asylum seekers pay no EST where they earn below AUD $9,240 per month, equivalent to AUD $110,800 per year.
Above that threshold, employment income is taxed at a maximum rate of 20%.
| Annual employment income | EST treatment |
|---|---|
| Up to AUD $110,800 | Exempt |
| Above AUD $110,800 | Taxed at a maximum rate of 20% |
Some secondary sources round the threshold to AUD $110,000; the figure published by the revenue authority is AUD $110,800 per annum.
Non-resident and expatriate workers are treated differently. Non-resident individuals engaged by the Republic or a state-owned enterprise as expatriate employees, and non-residents engaged in connection with employment in Nauru, fall under separate rate categories in the Schedule, each set by annual income bands.
The precise monetary bands within those non-resident categories were revised by the 2021 and 2022 gazette amendments. For the operative figures, consult the current Schedule and the rate tables published by the revenue office, because the full non-resident table is not reproduced here.
Ongoing Compliance in Nauru
Keep your Nauru entity compliant with filings, returns, and statutory obligations.
Taxing Employment Income: Salaries, Termination Payments, Allowances, and Superannuation
The EST applies to all employment income earned from sources in the country. Salaries and wages sit squarely within the charge, alongside service-fee income, both of which the revenue office confirms are in scope.
One category is clearly outside the net: fringe benefits are not taxed under the EST regime.
Superannuation operates as a parallel employer obligation. The revenue office runs compliance work to ensure employers meet Nauru superannuation law and that local employees accumulate their entitlements, which signals that employer contributions exist as a separate duty from the EST itself.
Termination payments and allowances are described in the official guidance, but the detailed statutory treatment is not set out in the public summaries available here. As a general principle, Pacific island EST regimes commonly fold termination payments and allowances into the employment income base; the specific position should be verified against the full text of the Employment and Services Tax Act before you rely on it.
Self-Employment and Service Fees: How Independent Contractors Are Taxed
Independent contractors are not outside the system. The EST reaches all independent service-fee income earned from sources in Nauru, covering self-employed individuals and non-residents who supply services there.
The rate matches employment income, so service fees are charged at the same percentages that apply to salaried earnings. A structural difference matters for cash flow: the charge falls on the gross amount earned from service fees, not on net profit after expenses.
What counts as a "service fee" is treated as a distinct question in the official Q&A guidance, which signals that the definition is an active administrative point worth checking against current guidance for your activity.
Contractors connected to the Regional Processing Centre face their own treatment. Non-resident persons providing services to or in connection with that centre are subject to a specific rate set in the Schedule, as amended by GN No. 122/2021.

Personal Exemptions, Allowances, and What Income Falls Outside the Charge
The main personal relief is the exemption already noted: protected residents pay nothing on annual income below AUD $110,800. Beyond that allowance, several categories of income and several taxes are simply absent.
- Fringe benefits are explicitly excluded from the EST charge.
- There is no capital gains tax, so gains on the disposal of assets are not taxed.
- No inheritance or wealth tax applies to individuals or to companies registered in the jurisdiction.
- There is no VAT or GST system.
Passive income deserves a careful distinction. The EST does not reach foreign-source passive income of resident individuals; where non-residents receive interest or royalties, any charge arises under the business-tax regime, not the EST. Dividend distributions to individuals are not listed as attracting a dividend tax under the published legislation.
Filing, Withholding, and Monthly Payment Obligations for Individuals
Most employees never file personally, because the system runs on employer withholding. Employers deduct EST from pay and remit it using monthly return forms submitted to the revenue office.
Self-employed individuals and registered businesses pay on a monthly cycle, with tax due on the 15th of the following month. Tax for October, for example, must be paid by 15 November.
Returns may be lodged electronically, with monthly EST return forms accepted by email. The revenue office issues both Monthly EST Withholding Tax Return forms and an Annual EST Withholding Tax Summary Return.
- All employers and payers must register for a Tax Identification Number with the revenue office.
- Financial records must be kept for at least five years.
- An annual EST withholding summary is required in addition to the monthly remittances.
Two timing points are worth holding together. Payments follow the monthly 15th-of-the-following-month rule, while the fiscal year itself runs from 1 July to 30 June; the exact due date for the annual summary should be confirmed with the revenue office.
What the Individual Tax Regime Means for Expatriates, Employees, and Investors
For many residents, the practical effect of the threshold is no liability at all, since earnings below AUD $110,800 escape the charge entirely. Foreign employees should look closely at which Schedule category applies to them, because the position differs sharply by role.
Expatriates employed by the Republic or a state-owned enterprise fall under a distinct rate Schedule introduced by GN No. 122/2021, and those connected to the Regional Processing Centre sit in yet another category. The figures within these bands are set by Regulation and should be read against the current Schedule.
Relief from double taxation cannot come from a treaty here.
Nauru has no double taxation agreements, so an expatriate cannot use a treaty to relieve double taxation. You must rely on home-country mechanisms, such as foreign tax credits or exclusions, instead.
United States citizens remain taxable on worldwide income regardless of where they live and must continue filing in the US, though the Foreign Earned Income Exclusion and Foreign Tax Credit may reduce the bill. Passive investors face a simpler picture: with no conventional personal income tax, residency carries no direct income tax consequence, because the EST is triggered only by employment or service-fee income with a Nauru source.
Financial-account reporting still reaches expatriates. The jurisdiction is a signatory to the Common Reporting Standard, so reporting financial institutions must identify account holders who are tax resident in other participating countries, a point detailed in the OECD residency note.
Outlook: Possible Reforms to the Taxation of Individual Income in Nauru
The clearest signal of direction comes from business taxation, not the EST. The Business Tax Act move to a worldwide basis for residents, effective 1 January 2021, broadened that base, while the EST has not followed with any equivalent extension to foreign-source individual income.
The government continues to work with international bodies toward OECD transparency standards and BEPS Inclusive Framework minimum standards, alongside PFTAC diagnostic outcomes. Tax transparency ratings have improved over time: the OECD upgraded the country's standing in July 2017, and the Global Forum ratified a "largely compliant" rating in June 2019 following a Fast Track review.
Base-broadening has been considered, but no consumption tax has been adopted, and no published proposal to extend the EST to foreign-source individual income has been announced. The trajectory points toward a wider base over time, yet the personal EST threshold and rate structure remain as set by the existing Schedule until any new Regulation is gazetted.
Conclusion
Personal income tax planning in Nauru is, at its core, a source-and-status question: whether income arises within Nauru and whether the earner is a resident determines exposure under the EST far more than rate arithmetic does. For a non-resident foreign business owner, that means the structure of any service arrangement or employment contract is the variable that most directly controls the tax outcome.
Before committing to a structure, confirm how Nauru's withholding and monthly payment obligations would fall on any individuals your entity engages there, because those mechanics impose compliance timelines that sit outside the rate discussion entirely.

Frequently Asked Questions
Not in the conventional sense. The closest instrument is the Employment and Services Tax under the Employment and Services Tax Act 2014, which charges employment income and independent service-fee income from Nauru sources rather than operating as a broad income tax on all personal earnings.
The maximum rate is 20%. For protected residents, namely Nauruan citizens, persons married to citizens, and resettled refugees and asylum seekers, income up to AUD $110,800 per year is exempt, and the 20% ceiling applies above that level.
Yes. Self-employed individuals and non-residents supplying services from a Nauru source pay EST at the same rate as employees, but the charge falls on gross service-fee receipts rather than on net profit.
Employers withhold EST and remit it monthly, and self-employed payers also pay on a monthly cycle, with tax due on the 15th of the following month. Returns can be submitted by email, and an annual EST withholding summary is required in addition to the monthly returns.
No. The jurisdiction has no double taxation agreements, so relief must come from home-country rules such as foreign tax credits or income exclusions. United States citizens, for instance, must still file at home but may apply the Foreign Earned Income Exclusion or Foreign Tax Credit.
No. The EST remains source-based and reaches only Nauru-source employment and service-fee income, even though the separate business-tax regime moved to a worldwide basis for residents from 1 January 2021.
