Introduction to Non-Resident Tax: Nauru's Withholding Tax on Outbound Payments
Nauru levies a withholding tax on certain outbound payments to non-residents, known as Non-Resident Tax (NRT). The charge sits within the Business Tax Act 2016 and applies a flat 20% to interest, royalties, and insurance premiums derived from sources in the country by a non-resident person. This is not a zero-withholding jurisdiction for those payment types, and because the country has signed no double taxation treaties, no reduced treaty rate is available to any recipient.
This article explains what NRT covers, how the 20% rate is calculated, when the obligation is triggered, what falls outside the net, and the duties and penalties that bind the payer. It is most relevant to foreign lenders, licensors, and insurers receiving Nauru-source income, and to the resident businesses that pay them and must withhold. The governing rules and consolidated legislation are published by the Nauru Revenue Office on its legislation page.
Legal Basis: The Business Tax Act and the Revenue Administration Act 2014
The primary statute is the Business Tax Act 2016, which has applied since 1 July 2016 and imposes three separate taxes: Small Business Tax, Business Profits Tax, and Non-Resident Tax. NRT is the withholding layer of that framework. Its charging provision subjects non-residents who derive interest, royalties, or insurance premiums from local sources to the rate set out in Schedule 1, while the operative withholding mechanics sit in section 44.
Procedure is handled by a companion statute, the Revenue Administration Act 2014, which commenced on 1 October 2014. That Act governs collection, recovery, and the administrative penalties that apply when tax is not withheld or remitted.
The Revenue Office issues binding public rulings on NRT through the Secretary for Finance. Payers facing an interpretive question can rely on those rulings, which remain binding on the Secretary until formally withdrawn.

Payments Caught by Withholding: Interest, Royalties, and Insurance Premiums to Non-Residents
Three categories of passive income trigger NRT when paid to a non-resident: interest, royalties, and insurance premiums sourced in the country. The list is exhaustive. A payment type not named here is not within the NRT net.
The charge bites only on amounts derived from local sources. Where the income is attributable to a permanent establishment of the non-resident in the jurisdiction, it is carved out of NRT and taxed instead under Business Profits Tax.
Service fees are deliberately excluded. Payments for services to non-residents are dealt with under a separate mechanism, the Employment and Services Tax, covered further below.
NRT applies to interest, royalties, and insurance premiums. Dividends and service fees sit outside it and follow different rules.
The Revenue Office has issued Taxation Determinations addressing whether each of the three payment types is deductible for the payer: TD 1-2020 for royalties, TD 2-2020 for insurance premiums, and TD 3-2020 for interest.
The 20% Non-Resident Tax Rate and How the Withheld Amount Is Calculated
NRT is charged at a single rate of 20%. It applies to the gross amount paid to the non-resident, with no deductions allowed against that base.
Because the levy is calculated on the gross figure, none of the recipient's expenses reduce the charge. A royalty of AUD 100,000, for example, yields AUD 20,000 of NRT regardless of the costs the licensor incurred to earn it.
The tax is final. Once the payer withholds and remits the 20%, the non-resident has no further filing obligation under the Business Tax Act in respect of those amounts.

|---|---|
| Rate | 20% |
| Tax base | Gross amount paid |
| Deductions | None allowed |
| Nature | Final tax |

Withholding on Service Payments: The Employment and Services Tax Mechanism
Payments for services to non-residents are not within NRT. They fall under the Employment and Services Tax Act 2014, which taxes employment income and independent service-fee income earned from local sources.
For a non-resident individual, both the employment tax rate and the services tax rate are 10%. The tax operates much like a withholding: the entity making the payment, rather than the recipient, accounts for it.
What matters is where the service is performed, not where the money moves. The gross amount earned from work or services rendered in the country is taxable whether or not payment is actually made there.
A contractor will not face services tax where the work is delivered through a permanent establishment of a non-resident in the jurisdiction; that income is captured by Business Profits Tax instead. Payers must lodge Monthly EST Withholding Tax Return forms and an Annual EST Withholding Tax Summary with the Revenue Office.
The Position on Dividends: Why No Withholding Applies at Source
Dividends paid to non-residents carry no withholding. The NRT charge is limited to interest, royalties, and insurance premiums, and dividends do not appear in that list.
The reason is structural. Profits are taxed at the company level under Business Profits Tax, and dividends distributed from after-tax profits carry no second withholding layer under the law as it stands.
With no double taxation agreements in force, no treaty provision alters this outcome in either direction. A foreign shareholder receiving a dividend from a resident company therefore faces no source-state withholding on that distribution.

When Income Is Treated as "Paid": Triggers for the Withholding Obligation
The duty to withhold arises when the relevant amount is paid. From that point, the payer has until 15 days after the end of the month of payment to remit the withheld NRT to the Secretary.
Failure to withhold does not reset the clock. Where the tax is not deducted and a deemed assessment follows, late payment penalty accrues from the original due date, being 15 days after month-end, not from the date the assessment is later raised.
A separate rule links remittance to the payer's own tax position. A Business Profits Tax deduction for a payment subject to NRT is withheld until the tax year in which the NRT has actually been paid to the Secretary, which gives the payer a direct financial reason to remit on time.
Exemptions and Payments Outside the Withholding Net
Several payment streams fall outside NRT altogether:
- Interest, royalties, or insurance premiums attributable to a permanent establishment of the non-resident in the country (taxed under Business Profits Tax instead)
- Service fees to non-residents (taxed under the Employment and Services Tax mechanism)
- Dividends paid by a resident company to non-resident shareholders
- Proceeds of asset disposals, since capital gains, inheritance, and wealth are not taxed
There is no domestic VAT or GST, so no indirect-tax withholding applies to cross-border payments either.
No formal NRT exemption certificate, reduced-rate application, or treaty-override procedure exists. This is consistent with the absence of any tax treaties to apply.
The Payer's Duties: Withholding, Record-Keeping, and Remittance Deadlines
The withholding obligation falls on the person making the payment. A resident person, or a permanent establishment of a non-resident, must deduct NRT from the gross amount before it leaves their hands.
Remittance is due within 15 days after the end of the month in which the income was paid. For Employment and Services Tax, the same timing applies: tax withheld for October, for instance, must reach the Revenue Office by 15 November.
Before any of this, payers must register for a Tax Identification Number with the Revenue Office. The OECD has published a TIN reference describing how identifiers are issued under the governing legislation.
Maintain accurate financial records for at least five years, file the required annual summary returns, and remember that your Business Profits Tax deduction for a payment is deferred until the related NRT is paid.
Penalties for Failure to Withhold or Remit
The consequences of getting this wrong rest squarely on the payer. A person who fails to withhold NRT becomes personally liable to pay the tax themselves.
The Revenue Administration Act treats non-compliance as a criminal offence: failing to withhold, or withholding and then failing to remit, can be prosecuted. On conviction, a person faces a fine of up to AUD 5,000, imprisonment of up to two years, or both.
The Revenue Office may instead pursue an administrative penalty as an alternative to prosecution, including a late payment penalty. That penalty runs from the date the tax was originally due, not from any later deemed assessment.
Beyond these direct sanctions, non-remittance also defers the payer's own Business Profits Tax deduction for the underlying payment until the NRT is settled. The compliance cost of delay is therefore both a penalty and a lost deduction.
Outlook: The Future of Withholding Tax in Nauru
Legislative direction points toward expansion rather than rollback. Amendments effective 1 January 2021 broadened the tax base to include the foreign income of resident persons, replacing the earlier purely territorial approach.
International cooperation is also deepening. The country has signed the OECD Multilateral Convention on Mutual Administrative Assistance in Tax Matters, and amendments to the Revenue Administration Act now allow for tax information exchange agreements with other states.
Earlier classification as an uncooperative jurisdiction has given way to transparency commitments. No announced plan exists to alter the 20% NRT rate, add new payment categories, or introduce withholding on dividends, and the absence of any treaty pipeline means no bilateral rate reductions are in prospect.
Conclusion
Withholding tax in Nauru places the compliance burden squarely on the payer, meaning a foreign business receiving payments from a Nauruan counterpart must confirm that counterpart understands and meets its obligations, since a failure to withhold creates penalties that can affect the commercial relationship on both sides. The decision that deserves the most attention is therefore not whether to receive income from Nauru, but whether the specific payment type falls under the 20% rate, the services mechanism, or an exemption, because that classification determines the entire cash-flow and compliance picture before any money moves.

Frequently Asked Questions
Non-Resident Tax is charged at a flat 20% on the gross amount of interest, royalties, or insurance premiums sourced in the country and paid to a non-resident. No deductions reduce the base, and because there are no double taxation treaties, no reduced rate is available.
No. The withholding charge is limited to interest, royalties, and insurance premiums, and dividends are not on that list. Profits are taxed at the company level under Business Profits Tax, so distributions to non-resident shareholders carry no further withholding.
The withheld NRT must reach the Secretary within 15 days after the end of the month in which the income was paid. The Employment and Services Tax follows the same timing, so tax withheld in October is due by 15 November.
No, service fees are explicitly excluded from Non-Resident Tax. They are instead taxed under the Employment and Services Tax mechanism, where the rate for a non-resident is 10% on the gross amount earned for services performed in the country.
The payer becomes personally liable for the tax and may face criminal prosecution, with a fine of up to AUD 5,000, imprisonment of up to two years, or both. As an alternative, the Revenue Office can apply an administrative late payment penalty that runs from the original due date.
No. The jurisdiction has no double taxation agreements in force, so no treaty-reduced rate or relief procedure exists for any non-resident recipient. The 20% rate applies regardless of the recipient's country of residence.
