Collection notes
- Legal Registration: Issued electronically by the Business Registries Office under the Companies Act 1995 upon registration of a domestic company; confirms company name, registration number, and date of incorporation. For overseas companies a Certificate of Registration of Overseas Company is issued instead. Both are delivered by email via the businessregistries.gov.to portal (launched December 2024). Registration fees range from TOP 100 to TOP 750 (approx. USD 40–100). Basic entity search (name, number, status, address) is free on the portal.
- Constitutive Documents: Filed with the Business Registries Office at incorporation under the Companies Act 1995 and Companies Regulations 2025. Companies may adopt a custom constitution or operate under the standard statutory constitution; if a custom constitution is used it must accompany the registration application (Form 1). The constitution sets out the company’s name, objects (if any), share capital, voting rights, and governance rules. For overseas companies, the equivalent constitutive documents from the home jurisdiction (memorandum and articles, certificate of incorporation) are filed instead.
- Tax Registration: The Ministry of Revenue and Customs issues a TIN Certificate upon tax registration. Businesses with taxable supplies exceeding TOP 100,000/year must also register for Consumption Tax (CT, 15%) and display a Consumption Tax Registration Certificate at each place of business. TIN is the single universal identifier for corporate income tax (25%) and CT. Registration via eTax portal at etax.revenue.gov.to or in-person at MRC offices at Tungi Colonnade Building, Nuku’alofa. TIN registration is free and issued immediately upon submission.
- Operating Permit: Required for all persons (individuals and companies) carrying on business in the Kingdom of Tonga under the Business Licences Act 2002 (as revised to 2020 Edition). Issued by the Business Registries Office, Ministry of Trade and Economic Development. Applications and renewals via the businessregistries.gov.to portal (since December 2024). The business licence is issued per business location; it bears the licensee name, business name, licence number, activity, and expiry date. Annual renewal required.
- Sector-Specific License: The National Reserve Bank of Tonga (NRBT) is the primary financial-sector regulator, licensing banks (Banking Act 2020), financial institutions (Financial Institutions Act 2004), microfinance institutions (Microfinance Institutions Act 2018), moneylenders (Moneylenders Act 2018), and foreign exchange dealers (Foreign Exchange Control Act). Insurance companies are regulated under the Insurance Act 2008 (NRBT oversight). The NRBT also hosts the Transaction Reporting Authority (TRA), Tonga’s financial intelligence unit for AML/CFT. Sector licences are issued by NRBT and displayed at the licensed entity’s premises.
- Governance Records: Companies must maintain a register of directors under the Companies Act 1995. Director information is on record at the Business Registries Office and is partially visible via the free public entity search on businessregistries.gov.to (scored 5/10 for public disclosure). The annual return lists current directors with addresses; the Long-Form Certificate of Good Standing also contains current director information.
- Signing Authority: Board resolution authorising a specific signatory to act on behalf of the company; no statutory form prescribed — standard company letterhead resolution is accepted practice. A notarised Power of Attorney is used where the authorised person is not a director. Tonga is a party to the Hague Apostille Convention (acceded 4 June 1970); documents can be apostillised for cross-border use.
- Address: Conduit universal policy: lease (no time bound) OR utility bill OR bank statement, with utility/bank dated within 90 days. Same evidence satisfies both registered-address and principal-place-of-business checks. Utility providers in Tonga include Tonga Power Ltd (electricity) and Tonga Water Board (water).
- Good Standing: Issued by the Business Registries Office via the businessregistries.gov.to portal (since December 2024). Three forms available: (1) Short-Form Certificate of Good Standing — recites entity name, registration number, and current status; (2) Long-Form Certificate of Good Standing — includes all current information including shareholders and directors; (3) Certified Historical Extract — current and historical information. Available to logged-in users of the portal; companies or their authorised agents can download directly. Confirm certificate is dated within 30–60 days for KYB purposes.

Notes
- The Business Registries Office launched a major new online registry system on 11 December 2024 (businessregistries.gov.to), replacing legacy paper-based processes. Companies, business licences, business names, and foreign investment certifications are all managed through this portal. Registration numbers and certificates are issued electronically.
- All overseas persons (foreign-registered entities and locally registered companies with foreign ownership) must obtain a Foreign Investor Certification from the Business Registries Office under the Foreign Investment Act 2002 before commencing business. This is separate from and additional to company registration.
- Tonga levies income tax on both individuals and companies under the Income Tax Act 2007 (Cap. 11.05). Individuals are subject to a progressive salary and wages tax (PAYE) withheld by employers, with a 0% band on annual income up to TOP 12,000, rising through 10% and 20% bands to 25% on the highest bracket. Corporate income tax is 25% on chargeable income. Consumption Tax (CT) at 15% applies to taxable supplies; businesses must register for CT when annual turnover exceeds TOP 100,000. All three taxes are administered by the Ministry of Revenue and Customs.
- The TIN format is not publicly standardised by MRC. No fixed regex is confirmed from official sources; collect the MRC-issued TIN Certificate and verify the number directly on the eTax portal (etax.revenue.gov.to) when in doubt.
- The Transaction Reporting Authority (TRA) operates within the NRBT as Tonga’s Financial Intelligence Unit (FIU). AUSTRAC provided the TAIPAN analytical system to TRA in December 2022. Suspicious transaction reports and threshold transaction reports are filed with the TRA.
- Tonga is a party to the Hague Apostille Convention (acceded 4 June 1970). Documents issued in Tonga can be apostillised for cross-border use through the relevant competent authority.
- Annual returns must be filed with the Business Registries Office every year. Failure to file more than 6 months after the due date triggers automatic deregistration (striking off). Verify active status via the free entity search on businessregistries.gov.to before accepting company documents.
- The Companies Act 1995 (Cap. 82) and Companies Regulations 2025 govern local companies. Overseas company registration is governed by the Companies Act 1995 and the Foreign Investment Act 2002 together.
