Key Takeaways
- Tax Information Exchange Agreements let Nauru share specified taxpayer information with partner jurisdictions on request, not automatically.
- Nauru's exchange commitments rest on a defined legal framework and align with OECD global transparency standards.
- Requests follow a structured process, and the information disclosed is bound by confidentiality rules and limits on use.
- Non-resident owners and advisers should understand which partners are covered and how the scope of a request affects them.
TIEAs and Nauru: Where the Jurisdiction Stands on Information Exchange
Nauru has no standalone bilateral Tax Information Exchange Agreements. Its exchange-of-information relationships rest instead on the multilateral Convention on Mutual Administrative Assistance in Tax Matters, supervised by the OECD Global Forum.
This matters to any foreign owner, investor, or adviser weighing a structure connected to the island, because the absence of bilateral TIEAs does not mean information isolation. The article explains what a TIEA does, why Nauru has none, how the multilateral route works in practice, and what the broader transparency picture means for a non-resident.
It is most relevant to those holding or planning to hold financial accounts or entities tied to Nauru, and to advisers assessing reporting exposure for clients resident elsewhere.
What a Tax Information Exchange Agreement Actually Does
A TIEA is a bilateral instrument that lets one country ask another for information tied to a specific tax investigation, civil or criminal. The OECD published the model in April 2002 as the standard for effective exchange under its work on harmful tax practices; the model itself binds no one, but supplies two templates that two governments can adopt.
The information covered is whatever is "foreseeably relevant" to administering and enforcing the tax laws of the parties. Crucially, a TIEA operates on request only: a country need not volunteer data it has not been asked for.
This is the feature that separates a TIEA from a double-tax treaty. The treaty exists to prevent the same income being taxed twice; the TIEA exists purely to move information so tax laws can be enforced.
Once an agreement is in place, neither bank secrecy rules nor a domestic limitation on collecting only what the local revenue itself needs can block the exchange. TIEAs have become the base layer for later frameworks, including Automatic Exchange of Information (AEOI) and the Common Reporting Standard (CRS).

Nauru's TIEA Network: How Many and With Which Partners
No bilateral TIEA instruments exist for the island. There is no OECD TIEA portal entry, no published partner list, and no signed bilateral agreement to be found in primary or secondary sources.
This sets the jurisdiction apart from Pacific and offshore peers such as the Cook Islands, the Marshall Islands, Samoa, and Vanuatu, all of which appear regularly as bilateral TIEA partners with major economies. Nauru does not.
Instead, its exchange network runs entirely through the multilateral Convention, covered in the next section. Membership of the OECD Global Forum dates from 2009, and the country applied to join the Convention on Mutual Administrative Assistance in Tax Matters thereafter.
One telling figure: despite being a party to that Convention, the country had received no exchange-of-information-on-request (EOIR) requests as of 2019. The explanation given is the very small economy and the absence of bank accounts on the island, not any deliberate shield.
The Legal Framework Behind Nauru's Exchange Commitments
The backbone of the country's commitments is the Convention on Mutual Administrative Assistance in Tax Matters, to which it is a participant. Domestic implementation flows through the Revenue Administration Act 2014, which sets the procedural rules for assessing, collecting, and enforcing tax; amendments to that Act now provide for implementing tax information exchange agreements.
Separate statutes carry the automatic side of the system. The Automatic Exchange of Financial Account Information Act 2016 empowers Cabinet to make CRS regulations, and the Automatic Exchange of Financial Account Information Regulations 2017 (Gazette No. 52/2017 and No. 527/2017) supply the detail.
| Element | Instrument or body |
|---|---|
| Multilateral basis | Convention on Mutual Administrative Assistance in Tax Matters |
| Tax administration | Revenue Administration Act 2014 |
| CRS primary law | Automatic Exchange of Financial Account Information Act 2016 |
| CRS regulations | Regulations 2017 (GN 52/2017, GN 527/2017) |
| Competent authority | Nauru Revenue Office (NRO) |
| Official legal database | RONLAW (ronlaw.gov.nr) |
The full text of every Act, gazette, and regulation sits in the official legal database, the Republic of Nauru's online repository. The competent authority for any exchange is the Nauru Revenue Office.

Scope of Information Covered Under a TIEA Request
Because no bilateral TIEA exists, there is no Nauru-specific schedule of covered records to cite. The general standard still describes what exchange would reach: information "foreseeably relevant" to administering and enforcing a partner's tax laws, civil or criminal.
A request may concern a person who is not resident in either party. The requested country must collect the information even where it holds nothing already and has no domestic use for it.
For the automatic channel, the CRS sweeps wider still. Financial institutions report data on financial accounts held by non-resident individuals and entities, and that data flows annually to the account holders' jurisdictions of tax residence without any request being made.
How an Exchange of Information Request Works in Practice
An EOIR request is never automatic; the requesting state must take the first step. Its competent authority sends a formal request that is foreseeably relevant to enforcing its own tax law, following the agreed procedure.
Before doing so, the requesting authority is expected to have exhausted its domestic sources and to confirm the request conforms to its own laws and to the exchange instrument. The OECD supplies a model request template to help authorities frame these submissions.
On the receiving side, the Nauru Revenue Office acts as competent authority. No published processing timeframe for responses has been retrieved.
As of 2019 the island had received zero EOIR requests, a function of its very limited economy and the absence of local bank accounts rather than any formal secrecy protection.

Confidentiality, Safeguards and Limits on Disclosure
Information moved under an exchange instrument carries confidentiality obligations. It may reach a court only to decide the tax matter at issue, and disclosure to anyone else in the receiving state requires the written consent of the supplying country's competent authority.
Many countries operate freedom-of-information regimes that open government files to the public. The OECD guidance is clear that a tax confidentiality clause overrides such legislation, so information received through exchange does not fall into the public domain by that route.
The Global Forum tests these safeguards directly. Nauru's 2019 EOIR peer review rated element C.3 (confidentiality) as Compliant, alongside Compliant ratings for elements A.3, B.1, B.2, C.1, C.2, and C.4.
A bilateral TIEA can be ended on six months' notice, yet the confidentiality clause survives termination, so data already exchanged stays protected.
TIEAs and the OECD Global Transparency Standards
The Global Forum on Transparency and Exchange of Information for Tax Purposes was founded in 2000 and restructured in September 2009. It is the body mandated to check that jurisdictions adopt and apply the EOIR standard and the automatic standards covering financial accounts under the CRS and crypto-assets under the Crypto-Asset Reporting Framework.
Nauru's review record runs through a Phase 1 review in 2013, a Supplementary Report in 2016, and a Second Round combined review adopted on 29 July 2019. That review gave the country an overall rating of Largely Compliant with the EOIR standard.
| Rating | Elements |
|---|---|
| Compliant | A.3, B.1, B.2, C.1, C.2, C.3, C.4 |
| Largely Compliant | A.1 (ownership/identity), A.2 (accounting records), C.5 (quality and timeliness) |
On the automatic side, the country signed the Multilateral Competent Authority Agreement for the CRS and put in place domestic rules requiring reporting financial institutions to identify account holders and controlling persons resident in other participating jurisdictions. CRS participation since 2018 means automatic exchange with more than 100 countries.
You can read the 2019 peer review in full for the underlying assessment. No post-2019 standalone EOIR report has been identified; a follow-up was due to the Peer Review Group by 30 June 2020, with no public outcome retrieved.
Scope of Information Covered Under a TIEA Request
The OECD Committee on Fiscal Affairs approved a Model Protocol in June 2015 that lets jurisdictions extend an existing TIEA to cover automatic and spontaneous exchange. That tool would only become relevant should the island ever negotiate bilateral agreements, of which there are none.
What This Means for a Non-Resident Owner or Adviser
The island sits inside both the on-request and the automatic transparency systems. For a foreign owner, the live exposure is the automatic one.
- Financial accounts held on the island by non-resident individuals and entities can be reported automatically to the holder's country of tax residence under CRS, which has run since 2018.
- The lack of bilateral TIEAs does not insulate any structure; multilateral Convention membership already reaches most OECD and G20 countries.
- Zero EOIR requests received reflects the tiny financial sector, not a legal barrier to exchange.
- Comprehensive controlled-foreign-company rules and broad anti-avoidance measures of the kind seen in larger jurisdictions have not been implemented here.
Any arrangement touching a financial institution or entity on the island should be planned around CRS reporting, since the partner list set out in GN No. 527/2017 is broad. Before extending a business across borders, examine the exchange clauses that would apply and the conditions under which data could move.
The primary transparency risk for a non-resident here is automatic CRS reporting to your home jurisdiction, not a bilateral TIEA. Treat any local account or entity on that basis.
Outlook: The Future of Nauru's Information Exchange Position
The Global Forum assessment recorded real improvement in the country's legal and administrative frameworks, while noting that full operation of the compliance and enforcement regime arrived only at the end of the 2019 review period or later. The recommendation was to keep strengthening supervision and enforcement.
In 2025 the Global Forum moved to an enhanced monitoring process, tracking EOIR compliance on a continuing basis rather than through fresh full peer reviews. The island would fall under this monitoring instead of a new standalone review.
More than 70 jurisdictions have committed to the Crypto-Asset Reporting Framework, with first automatic exchanges of crypto-asset data due from 2027; the country's position on CARF is not yet confirmed in the sources retrieved. Targeted Global Forum capacity-building for Pacific Islands jurisdictions could speed up work on the remaining EOIR recommendations.
The direction is toward more transparency, not less. CRS since 2018, Convention membership, and a Largely Compliant EOIR rating together suggest a tightening environment, which makes bilateral TIEAs a lower priority yet a plausible future step. No specific bilateral TIEA negotiations have been identified.
Conclusion
A foreign owner should treat Nauru as a participant in the international tax transparency system rather than as a place outside it. There are no bilateral TIEAs, but the multilateral Convention and live CRS reporting already connect it to most major economies, and the trend points toward closer alignment with OECD standards. Build any structure on the assumption that account and entity information can reach your country of tax residence, and confirm the reporting position before you commit.

Frequently Asked Questions
No standalone bilateral TIEAs have been identified for Nauru in any primary or secondary source. Its exchange relationships run through the Convention on Mutual Administrative Assistance in Tax Matters instead, which reaches most OECD and G20 countries.
Yes. Through the multilateral Convention, partner countries can request information on request, and under CRS, financial account data on non-residents is exchanged automatically each year. The lack of bilateral instruments does not mean information isolation.
As of 2019 it had received no EOIR requests at all. This reflects the very limited size of its economy and the absence of local bank accounts, not any legal protection against exchange.
The 2019 Second Round review, adopted on 29 July 2019, rated the jurisdiction overall as Largely Compliant with the EOIR standard. Confidentiality and several other elements were rated Compliant, with Largely Compliant ratings for ownership information, accounting records, and the quality and timeliness of responses.
The automatic CRS regime is the principal exposure. Financial accounts held by non-resident individuals and entities can be reported to their jurisdiction of tax residence, since CRS has operated on the island since 2018 across a broad list of partner countries.
It is plausible but not confirmed. No bilateral negotiations have been identified, and the existing multilateral and CRS frameworks already cover most exchange needs, which makes new bilateral agreements a lower priority for now.
