Key Takeaways
- TIEAs provide exchange of information on request and, unlike a double tax treaty, deliver transparency rather than any tax relief.
- Requests follow a defined process, and the information covered is matched by confidentiality rules that limit how disclosed data can be used.
- Non-resident owners and advisers should understand which partners Samoa exchanges with and how the legal framework supports those obligations.
- Samoa's alignment with OECD transparency standards shapes the current network and the outlook for future information exchange.
TIEAs in Samoa: What Exchange of Information on Request Really Means
A Tax Information Exchange Agreement, or TIEA, is a bilateral instrument under which two governments agree to share tax data on request. TIEAs in Samoa operate through the Exchange of Information on Request (EOIR) standard set by the OECD, administered domestically by the Ministry of Customs and Revenue.
Samoa entered the EOIR system in 2009 and now sits within the OECD Global Forum framework, holding a "Largely Compliant" rating from its 2019 peer review. For a foreign owner of a Samoan company, trust, or other vehicle, this matters because it determines when your home tax authority can obtain information about your structure.
This article explains how the request mechanism works, which countries are partners, what information can be disclosed, and where the limits lie. It is written for non-resident owners and their advisers assessing exposure before they incorporate or while they maintain a Samoan entity.
How a TIEA Differs from a Double Tax Treaty: No Relief, Only Transparency
A TIEA does one thing: it compels the transfer of tax information between competent authorities on request. It grants no reduction in withholding rates, no allocation of taxing rights, and no relief from double taxation.
A Double Tax Treaty (DTC) does the opposite work. It allocates taxing rights between two states and lowers or removes tax at source, while a TIEA touches none of these and serves only as a disclosure channel.
The distinction is visible in practice. Australia and Samoa signed a TIEA in 2009 and, separately, a companion "Agreement for the Allocation of Taxing Rights" covering retirees, government employees, and students and providing a route to resolve transfer pricing disputes.
That a second agreement was needed for those functions confirms the point: the TIEA itself does not allocate or relieve anything. TIEAs also tend to require signatory states to subordinate domestic secrecy rules to the exchange obligation, a feature absent from most classic treaties.

Samoa's TIEA Network: How Many Agreements and With Which Partners
Samoa signed its first TIEA in 2009, and the Ministry of Customs and Revenue records that the initial batch covered 13 jurisdictions. That figure is the most reliable official count available.
The authoritative partner list is maintained by the Ministry of Foreign Affairs and Trade on its dedicated TIEA page. Each agreement is bilateral, so a foreign owner's exposure depends entirely on whether their home country sits on that list.
| Country | TIEA with Samoa | Note |
|---|---|---|
| Australia | Yes, signed 16 December 2009 | Companion taxing-rights agreement also signed |
| United States | No | US obtains data on US persons via FATCA/IGA instead |
Samoa appears among the Asia-Pacific jurisdictions that have entered TIEAs, alongside Brunei, the Cook Islands, Hong Kong, Macao, the Marshall Islands, and Vanuatu. Advisers should confirm a client's specific home jurisdiction against the Foreign Affairs list rather than assume coverage.
The presence or absence of a TIEA is country-specific. Check the Ministry of Foreign Affairs partner list for the exact jurisdiction before drawing conclusions about disclosure exposure.
The Legal Framework Behind Samoa's Commitment to Information Exchange
Three statutes underpin tax information exchange: the Income Tax Act 2012, the Tax Administration Act 2012, and the Tax Information Exchange Act 2012. The last of these is the operative instrument for TIEAs.
The Tax Information Exchange Act 2012 authorises the Minister to enter agreements covering taxes on income or profits, capital, net wealth, and estate, inheritance or gift taxes, plus any substantially similar tax. Its purpose extends to assessment, collection, enforcement, and the investigation or prosecution of tax matters.
Critically for a foreign owner, the same Act overrides domestic secrecy. A lawful obligation of confidentiality or non-disclosure does not block exchange under a valid TIEA, and the Commissioner of Inland Revenue holds enforcement authority over the regime.
Samoa joined the BEPS Inclusive Framework as an Associate on 4 February 2021, extending its transparency commitments beyond bilateral agreements. The Competent Authority for all EOIR, AEOI, and BEPS matters is the Ministry of Customs and Revenue, Level 4, DBS Building, Apia.

Scope of Information Covered Under a Samoan TIEA
The taxes within reach are wide. Income or profits taxes, capital taxes, net wealth taxes, estate, inheritance and gift taxes, and any identical or substantially similar levy of either state all fall under the Tax Information Exchange Act 2012.
Exchange is permitted to help determine, assess, and collect tax, to recover and enforce tax claims, and to investigate or prosecute tax matters. The Australia agreement covers both civil and criminal tax matters, the standard OECD-model formulation.
The information that can be requested follows the Global Forum peer-review elements:
- Ownership and beneficial ownership records, plus identity information (element A.1)
- Accounting records (element A.2)
- Bank account details (element A.3)
Requests must concern information that is "foreseeably relevant" to the requesting country's tax administration. A request without a defined tax subject, a so-called fishing expedition, is not something Samoa is obliged to fulfil.
How a Request for Information Works in Practice
Nothing moves automatically under a TIEA. Information passes only when the competent authority of one government sends a formal request to its counterpart, and the agreement sets out what that request must contain.
- The requesting state's tax authority sends a written request to the Ministry of Customs and Revenue in Apia.
- The request must name the taxpayer, describe the information sought, state the tax purpose, and explain why the data is foreseeably relevant.
- Inland Revenue Services, under the Ministry, locates and retrieves the information from holders such as banks, registered agents, and trust and company service providers.
- The information is transmitted to the requesting authority and treated as confidential under the terms of the agreement.
Samoa must use its best endeavours to ensure that domestic rights and safeguards are not applied in a way that unduly delays effective exchange. No statutory response deadline appears in the legislation; the OECD standard expects a reply within 90 days, but that is a soft benchmark enforced through peer review rather than a hard legal limit.

Confidentiality, Safeguards and Limits on Disclosure
Information shared under the Australia–Samoa agreement is confidential under Article 8 of that text. The rights and safeguards a person holds under the laws or administrative practice of the requested state continue to apply.
Use is limited. A receiving authority may use the information only for the tax purposes specified in the request, may disclose it in public court proceedings or judicial decisions, but may not pass it to any other person or entity.
Several grounds let a requested state decline. Legal professional privilege, public policy, national security, and the principle that no state need act contrary to its own laws all remain available as limits.
Domestic secrecy, by contrast, is not a valid ground. The Tax Information Exchange Act 2012 expressly subordinates Samoan confidentiality rules to a valid request, so bank or corporate secrecy alone will not shield a structure. Whether a Samoan agreement requires the taxpayer to be notified before information is shared is not settled in the sources here; the OECD model permits notification but does not require it.
TIEAs and the OECD Transparency Standards: Where Samoa Stands
Samoa is a member of the OECD Global Forum on Transparency and Exchange of Information for Tax Purposes. Its standing has risen over successive reviews.
| Review | Year | Rating |
|---|---|---|
| First Round (2010 ToR) | 2015 | Partially Compliant |
| Fast-Track review | 2017 | Largely Compliant (provisional) |
| Second Round | 2019 | Largely Compliant |
The 2019 report records improvement across several elements, including ownership and identity information and the quality and timeliness of responses, all of which moved up from the earlier round. A "Largely Compliant" rating means the standard is implemented to a large extent, with some material but limited-impact deficiencies remaining.
Automatic exchange runs alongside the request channel. Samoa began Automatic Exchange of Information under the Common Reporting Standard in September 2018, so it engages in both EOIR and AEOI.
What TIEAs Mean for a Non-Resident Owner or Adviser
If you own or control a Samoan entity, an International Company, an LLC, or a trust, a TIEA offers no shield against disclosure to your home tax authority where that authority files a valid, foreseeably-relevant request. Your actual exposure turns on whether your home country has an agreement or equivalent arrangement with Samoa.
Two channels deserve separate attention. A TIEA is reactive and request-based; CRS reporting is automatic, sending financial account data such as balances, interest, and dividends to committed partner jurisdictions each September regardless of whether a TIEA exists.
The instrument that applies varies by client. Australia uses its 2009 TIEA, while the United States, absent from the TIEA list, draws information on US persons through FATCA and intergovernmental agreements, so advisers should match the instrument to each home jurisdiction.
Beneficial ownership is a primary target of any request. The Companies Act 2017 introduced the beneficial owner definition and the duty to keep ownership records, and trust and company service providers licensed by the Samoa International Finance Authority, under the Central Bank of Samoa, must produce that information on demand from the revenue authority.
A TIEA imposes no Samoan tax on a non-resident. It is purely an information mechanism with no rate or liability consequence inside the jurisdiction itself.
Outlook: The Future of Information Exchange in Samoa
The direction of travel is toward wider, deeper exchange. Having joined the BEPS Inclusive Framework in February 2021, Samoa runs the bilateral request channel and automatic CRS flows in parallel, treating the two as complementary rather than alternative regimes.
The 2019 review left recommendations on the availability of ownership and identity information and on timeliness, which Samoa is expected to address under ongoing Global Forum monitoring. As a Global Forum member, the jurisdiction will also fall within monitoring for the Crypto-Asset Reporting Framework (CARF), which extends automatic reporting to crypto assets.
Regional momentum reinforces this. The OECD's Tax Transparency in Asia 2026 Initiative, whose progress report appeared on 6 June 2026, tracks transparency gains across the region, and Samoa sits within that framework's scope. Whether the network expands through further bilateral TIEAs, accession to the Multilateral Convention, or a move toward a public beneficial ownership register is not confirmed in available sources.
Conclusion
TIEAs in Samoa are a transparency tool, not a tax. For a foreign owner, the practical reality is that domestic secrecy will not block a properly framed request, beneficial ownership records are accessible to the revenue authority, and CRS reporting flows automatically alongside the request channel. The sound approach is to confirm whether your home country holds an agreement with Samoa, to structure on the assumption that information may be shared, and to keep accurate ownership and accounting records that will stand scrutiny.

Frequently Asked Questions
No. A TIEA shares information only and carries no tax rate, relief, or liability effect inside Samoa. Reductions in withholding or relief from double taxation come from a Double Tax Treaty, which is a separate instrument.
The Ministry of Customs and Revenue records an initial batch covering 13 jurisdictions when Samoa entered the EOIR system in 2009. The authoritative partner list is maintained by the Ministry of Foreign Affairs and Trade, which advisers should check for any specific home country.
No. The US Treasury's published TIEA list does not include Samoa. The United States instead obtains information on US persons through FATCA and intergovernmental agreements rather than a TIEA.
No. The Tax Information Exchange Act 2012 subordinates domestic secrecy and confidentiality rules to a valid TIEA request, so bank or corporate secrecy alone will not prevent disclosure. A requested state may still decline on narrow grounds such as legal professional privilege or public policy.
Both channels operate. A TIEA shares information only when a competent authority sends a specific request, while CRS reporting transmits financial account data automatically each September to committed partner jurisdictions, regardless of whether a TIEA exists.
The OECD Global Forum's 2019 Second Round peer review rated Samoa "Largely Compliant," an improvement on the "Partially Compliant" rating from the 2015 First Round. The rating indicates the standard is implemented to a large extent with some remaining deficiencies of limited practical impact.
