- Non-resident owners face practical considerations around obtaining and using a Samoan TIN that differ from those of local applicants.
Tax ID in Samoa: What Foreign Owners Need to Know
A Tax Identification Number, or TIN, is the number the Samoa Ministry for Revenue assigns for tax purposes, and it sits at the centre of how a business meets its obligations in this independent Pacific state. The point that surprises most foreign owners is that the TIN is not handed automatically to every tax resident; it is tied to holding a business licence, a rule set out in the Tax Administration Act. This article explains when a Samoan TIN is issued, how to apply, what documents you need, and how the number functions for filing, banking, and information exchange.
It matters most to non-resident investors and advisers weighing a company in this jurisdiction, and to anyone whose financial account here will be reported under international standards.
Does Samoa Issue a Tax Identification Number?
Yes. The Ministry for Revenue issues a TIN as the official identifier for tax matters, governed by Sections 12 to 14 of the Tax Administration Act 2012.
The number reaches individuals, businesses, and legal entities, but only on a specific trigger: it is granted to those engaged in a business or economic activity who obtain a business licence. Passive tax residents do not receive one by default.
This article concerns the independent state of Samoa. American Samoa is a US territory with a separate tax system administered by the IRS, and its rules do not apply here.

The TIN System and the Samoa Ministry for Revenue
The Samoa Revenue Service, operating under the Ministry for Revenue, issues TINs and keeps the register of taxpayers compliant with their obligations. Its public portal is revenue.gov.ws, and online filing runs through the Samoa eTax (SET) system.
The Ministry was formerly styled the Ministry of Customs and Revenue; current branding reads simply "Ministry of Revenue." A memorandum of understanding with the Samoan Institute of Accountants formalises cooperation on tax matters, and tax agents are recognised in their own right under the same governing Act.
Note one practical limitation for researchers: at the date of the OECD's published TIN information sheet, no dedicated TIN guidance appeared on the Ministry's own domestic website. Much of the verifiable structural detail therefore comes from the OECD record rather than a local page.
Who Must Obtain a Samoan Tax ID
The main trigger is straightforward. When an individual undertakes business or economic activity and applies for a business licence, the TIN is issued on approval of that licence.
A second route catches employers. A person not directly in business but employing staff to run their organisation is also brought into the system, with the number appearing on their Confirmation Letter for Registration rather than on a licence certificate.
| Holder type | TIN issued |
|---|---|
| Sole trader (individual business) | Yes |
| Individual partner in a partnership | Yes |
| Partnership entity | Yes |
| Company | Yes |
| Trust (including charitable trust) | Yes |
| Non-profit organisation | Yes |
| Statutory body | Yes |
| Passive tax resident with no licence | No |
Every entity must hold a business licence before a TIN can be issued to it. For a foreign owner, that sequence matters: licensing comes first, the tax number follows.

Format and Structure of the Samoan TIN
There is no defined segment structure for the Samoan TIN. Numbers are sequential integers assigned by reference to the last one issued, with allocation having begun from 70004.
The number is purely numeric, with no confirmed letters, hyphens, or check-digit formula in official sources. One unified TIN serves across individuals, businesses, and entities; the jurisdiction does not run separate categories of tax number.
A note on a common claim: a third-party source states the TIN runs to nine digits for both individuals and businesses. The OECD's official TIN sheet, the primary record, confirms only sequential integers without a fixed length, so treat the nine-digit figure with caution.
The TIN appears on all Business Licence Certificates, on the firm's invoices and receipts, and on every notice the Ministry sends to a business.
How to Apply for a Tax ID in Samoa
The standard path is the business licence application itself. Approve that, and the TIN is granted; there is no separate stand-alone TIN form for most applicants.
Two channels exist:
- Online, through Samoa eTax (SET). The registration page asks for the applicant's full name, email address, a chosen username, and the TIN of the business being registered. After submission, the Ministry contacts the applicant to confirm identity, typically within three to five working days.
- In person, by visiting the local Samoa Revenue Service office and completing the paperwork. The office sits at Level 4, Development Bank Building, Beach Road, Apia, and recorded walk-in waits range from about five minutes to two hours.
On the available public information, there is no fee for obtaining a TIN.

Documents Required for TIN Registration
Individuals supply a valid identification document, such as a passport or birth certificate. A business provides its registration certificate, proof of business address, and identification for the owner or owners.
No specific public guidance was found on extra apostille, notarisation, or certified-translation requirements for non-resident entities. As a general matter, a non-resident applying through an agent supplies certified copies of formation documents together with director and shareholder identification, and only registered tax agents (or lawyers performing legal work) may accept fees and advertise as such.
How the Tax ID Differs from Company Registration and Other Numbers
These two numbers come from different places. The TIN is issued by the Ministry for Revenue for tax purposes, while company incorporation and its registration number come from a separate registry; the two are not interchangeable.
Once assigned, a single TIN does several jobs. The holder uses it to register, file, pay, and claim refunds for income tax, VAGST (Samoa's value-added tax), PAYE, provisional tax, and withholding tax.
There is no separate VAT number. The TIN is the VAT identifier, used for VAGST filings, collections, and remittances.
The TIN is also distinct from the Global Intermediary Identification Number (GIIN) that a Samoan financial institution obtains from the IRS for FATCA reporting. That is a financial-institution registration, not a taxpayer number.
What the Tax ID Is Used For: Filing, Banking and Self-Certification
Beyond filing income tax, VAGST, and PAYE, the TIN carries the holder's provisional tax and withholding tax obligations under one identifier. It is the reference the Ministry expects on returns and correspondence.
The number also surfaces in information exchange. Samoa is a CRS-participating jurisdiction and began due diligence on new accounts from 1 January 2017, in an early reporting wave alongside Australia, New Zealand, the Bahamas, and others.
Reporting Financial Institutions register on the Ministry's MDES platform and collect required data from account holders, including tax residency, TIN, account details, and controlling persons. A self-certification form confirms the account holder's jurisdiction of tax residence and records the TIN and date of birth; without it, an institution cannot meet its CRS obligations.
For banking, expect to give your home-country TIN on CRS self-certification forms when you open or hold a Samoan account, and be ready for foreign banks to ask for the Samoan entity's TIN as part of their own KYC checks. On FATCA, no signed Intergovernmental Agreement between Samoa and the United States was confirmed in retrieved sources, which means Samoan institutions may register directly with the IRS as participating FFIs; verify current status against the US Treasury table.
Practical Considerations for Non-Resident Owners
The licence-first rule has a direct consequence for foreign shareholders. A non-resident who is merely a passive shareholder in a Samoa company may never hold a Samoan TIN in their own name, because the number attaches to business activity and a licence, not to ownership.
That does not remove your tax footprint. Non-resident withholding tax applies where a person in this jurisdiction pays interest, royalties, insurance premiums, management fees, professional service fees, or natural resource amounts to a non-resident, and the Ministry of Finance issues a P5 Withholding Certificate as evidence of payment on government contracts involving non-residents.
New Zealand residents should check the double tax agreement between Samoa and New Zealand, and confirm any NZ Inland Revenue obligations, before bidding or contracting.
In CRS exchange, the primary identifier reported for a non-resident is your home-country TIN, not a Samoan one. Keep it accurate on every self-certification form a Samoan bank gives you.
For information exchange thresholds, accounts below USD 1 million receive simplified review, while those of USD 1 million or more attract enhanced review including a relationship manager inquiry. No specific public data was found on processing times for non-resident TIN applications or on remote and proxy filing; engaging a locally registered tax agent or law firm is the usual route.
Conclusion
A Samoan TIN follows a business licence rather than residence, so for most foreign owners the practical question is whether the entity or activity needs licensing at all. If it does, the number is free, issued by the Ministry for Revenue, and serves as your single reference for income tax, VAGST, PAYE, and withholding. If you are a passive shareholder, your home-country TIN, not a Samoan one, will carry most of the weight under CRS reporting. Confirm FATCA status and any treaty position before you commit, and use a local agent where remote filing is unclear.
