Key Takeaways
- Companies operating in Samoa face corporate income tax on a residence-based liability, with the tax base built from computed company profits.
- Foreign-owned businesses should review how permanent establishments and international company exemptions affect their position before establishing a presence.
- Compliance involves filing returns, meeting provisional tax and payment obligations, and avoiding penalties tied to late filing and late payment.
- Looking ahead, the BEPS agenda and the OECD global minimum tax under Pillar Two may shape reform and influence planning for non-resident investors.
Understanding Corporate Income Tax in Samoa
Corporate income tax in Samoa is a real and actively enforced charge, not a nominal one. Companies that are resident in the country, and non-resident companies earning income sourced from within it, pay tax on their net profits at a flat rate of 27%, under a framework built on the Income Tax Act 2012 and its administrative companion, the Tax Administration Act 2012.
A separate track exists for International Companies registered under the International Companies Act, whose offshore profits carry an effective rate of 0%. The two regimes sit side by side, and which one applies to you depends entirely on where your income is sourced and how your entity is structured.
This article explains how the corporate tax (often referred to locally as company income tax) is calculated, filed, and paid, the deductions and incentives available, and how foreign ownership and global minimum tax reform affect the picture. It is written for non-resident owners, investors, and their advisers weighing incorporation or assessing an existing entity's obligations.
Legal Basis: The Income Tax Act 2012 and Company Income Tax
Two statutes carry most of the weight. The Income Tax Act 2012 sets out what is taxed and at what rate; the Tax Administration Act 2012 governs assessment, filing, and enforcement.
Both were assented to on 25 June 2012 and commenced on 1 January 2013. The administration Act replaced the older Income Tax Administration Act 1974, modernising the procedural rules that surround a company's annual obligations.
The wider framework also includes the Excise Tax Act 1984, the Tax Information Exchange Act 2012, and the Value Added Goods and Services Tax Act 2015. For corporate income tax, however, the first two Acts are the ones you will deal with most.
Every company must lodge an annual income tax return in the prescribed form, known as Form IR4. The full statutory text is published by the Ministry of Customs and Revenue and mirrored on the Pacific Islands Legal Information Institute, so the source language is open to inspection rather than locked away.

Corporate Income Tax Rate and Residence-Based Liability
The headline rate is 27%, and it does not vary by company size or sector for ordinary trading entities. Resident companies pay 27% on income derived in the jurisdiction; non-resident companies pay the same 27% on income that is sourced there.
| Entity type | Income covered | Effective rate |
|---|---|---|
| Resident company | Samoa-sourced income | 27% |
| Non-resident company | Samoa-sourced income | 27% |
| International Company (IC) | Offshore profits | 0% |
The dividing line that matters most to a foreign owner is between an ordinary company and an International Company. ICs registered under the International Companies Act are exempt from local income tax, and their offshore profits are effectively untaxed.
ICs are generally non-resident in character and do not derive income from within the country. What makes a company "resident" is a separate question with its own rules, covered in the dedicated residency article rather than here.
Determining the Tax Base: How Company Profits Are Computed
The 27% rate applies to net profit, meaning assessable income less allowable deductions, not to gross turnover. Assessable income is broadly all income a company derives from business or investment activity conducted in or sourced from the country.
A company may use either the cash basis or the accrual basis to account for its income and expenditure, provided the same basis is applied consistently to both sides.
- On the cash basis, income is derived when received and expenditure is incurred when paid.
- On the accrual basis, income is derived when it becomes due and expenditure is incurred when it becomes payable.
A "small business" carries a narrower definition tied to the VAGST registration threshold: it is a business run by an individual whose annual assessable income falls below that threshold and who is not VAGST-registered. That category sits in the personal income tax sphere rather than the corporate one, so it rarely affects an incorporated foreign-owned entity.

Allowable Deductions and Loss Relief for Companies
Ordinary operating costs reduce the tax base. Salaries, rent, utilities, and supplies are deductible as the routine expenses of running a business, and employer payments such as bonuses, gratuities, retiring allowances, and lump-sum redundancy amounts are also allowed.
Capital assets are written down over time rather than expensed at once. Straight-line depreciation applies the IFRS-determined rate to the cost of assets such as machinery, equipment, and buildings.
Bad debts may be deducted where the conditions set out in the Act are met. For intangible assets, the cumulative deductions claimed across the current and all prior years cannot exceed the original cost of the intangible.
Where deductions for a year exceed assessable income, the company has a loss. That loss carries forward to the next year and is set against assessable income; any unused balance rolls forward again, year after year, until absorbed.
The Act allows losses to be carried forward, but a specific cap on the number of years is not clearly stated in public sources. Carry-back of losses is not a standard feature of Pacific Island regimes, so do not assume it is available; verify both points against the consolidated Act before relying on them.
Filing, Provisional Tax, and Payment Obligations
The tax year runs from January to December, with a balance date of 31 December. Every business must file its annual return within three months of year-end, which fixes the deadline at 31 March of the following year.
A company wanting a different balance date must obtain the Commissioner's approval before adopting it. Absent that approval, the standard December year-end and March filing date apply.
Form IR4 is the prescribed return for companies. The system is one of self-assessment, with provisional tax payable during the year based on the prior year's taxable income; the precise instalment schedule should be confirmed with the revenue authority, since provisional tax is typically split across the year.
- File Form IR4 by 31 March following the December year-end
- Pay provisional tax during the year, calculated on the prior year's liability
- Use the Samoa eTax (SET) portal to file returns, pay, and view statements
The Tax Invoice Monitoring System (TIMS), launched in 2020, captures transactions across business entities and feeds the revenue authority's view of trading activity. For a foreign-owned company operating locally, this means transaction-level reporting is part of day-to-day compliance, not just an annual event.

Penalties for Late Filing and Late Payment
Missing a payment deadline triggers a penalty of 10% on the unpaid tax once the grace period from the due date has passed. This sits on top of "late payment interest" charged separately under the Tax Administration Act 2012.
A distinct late-filing penalty generally applies independently of the late-payment charge, though the exact rate and the length of the grace period are not set out in public sources; the official IRS notice on deadlines and penalties is the place to confirm current figures. Continued non-compliance can escalate to mounting interest and legal action, so a missed return is best corrected quickly rather than left to accrue.
Tax Incentives and Reduced-Rate Sectors for Companies
Incentives are targeted, not general. Tourism is the clearest example: tax-resident investors in the sector can access import duty exemptions and certain tax holidays, subject to meeting investment, employment, and performance conditions.
These reliefs come with strict qualifying rules. Minimum investment amounts and job-creation targets are typical conditions, and a holiday usually runs for a defined number of years measured from the start of the qualifying investment.
The single most valuable preference is the International Company regime. An IC registered under the International Companies Act faces an effective 0% rate on offshore profits, which is why the structure is used for holding companies, trading companies, and asset-protection and wealth-management vehicles.
Foreign-Owned Companies, Permanent Establishments, and International Company Exemptions
For a foreign-owned company earning income within the jurisdiction, the rate is the same 27% that applies to local resident companies. There is no surcharge or reduced rate purely on the basis of foreign ownership; what matters is the source of the income.
The country has concluded tax treaties with several partners to support investment and reduce double taxation. Where a company from a treaty country operates locally, the treaty may lower withholding tax on dividends, interest, and royalties; outside a treaty, certain payments under the Income Tax Act 2012 attract a 15% withholding tax.
The International Company route changes the calculation entirely. An IC is exempt from local income tax, with an effective 0% rate on foreign-sourced profits and exemptions extending to stamp duties on international transactions, because such companies are typically non-resident and earn nothing from within the country.
The exact statutory definition of a permanent establishment, and the identity of the treaty partners whose agreements are in force, are not set out in the public sources reviewed here. If your structure depends on either point, confirm it against the consolidated Act and the relevant treaty text before committing.
Corporate Tax Outlook: BEPS, the OECD Global Minimum Tax (Pillar Two), and Reform
In October 2021, more than 135 jurisdictions backed the OECD/G20 plan that includes the Global Anti-Base Erosion rules. Those rules aim to ensure that large multinational groups pay a minimum level of tax wherever they operate.
Pillar Two sets a global minimum effective rate of 15% and applies to multinational groups with annual revenue above EUR 750 million. The threshold deliberately confines the rules to the largest groups, keeping smaller businesses outside their reach.
The GloBE rules operate as a "common approach": a jurisdiction is not compelled to adopt them, but if it does, it must implement them as agreed. In January 2026, the Inclusive Framework on BEPS agreed a "Side-by-Side" package setting out coordinated operation of the global minimum tax arrangements.
The pressure point for the country lies in its dual structure. A 0% offshore regime for International Companies alongside a 27% domestic rate is exactly the kind of arrangement the Income Inclusion Rule and Undertaxed Profits Rule are designed to reach from the parent jurisdiction's side, even where the source country itself levies nothing.
Whether the jurisdiction has formally joined the Inclusive Framework, or enacted any domestic Pillar Two measure such as a qualified minimum top-up tax, is not confirmed in public sources. Many small Pacific states have not yet legislated their own rules, yet an IC's ultimate parent country may still apply a top-up tax on its low-taxed profits.
A 0% IC rate does not guarantee a 0% group outcome. For multinational groups above the EUR 750 million revenue threshold, profits left untaxed locally may be topped up to 15% in a parent jurisdiction under the GloBE rules, so the saving you expect may not survive at group level.
Conclusion
For a foreign business owner, the permanent establishment rules and the scope of any international company exemptions are the fork in the road: they determine whether Samoa's corporate tax applies at all, making that threshold question more consequential than the rate itself. Once presence is confirmed, compliance timing governs real cost, because Samoa's penalty regime attaches to procedural failures as directly as it does to unpaid tax.
The thread worth watching after that is not an abstraction but a specific policy direction: Pillar Two sets a floor that could erode the value of any reduced-rate incentive a foreign-owned structure currently relies on, which means the compliance picture today may not be the compliance picture at the next filing cycle.

Frequently Asked Questions
The flat rate is 27% on net taxable profit, and it applies to both resident companies on their locally derived income and non-resident companies on income sourced within the jurisdiction. There is no separate small-company rate for incorporated entities.
No. An International Company registered under the International Companies Act is exempt from local income tax, and its offshore profits carry an effective rate of 0%, with further exemptions for stamp duties on international transactions. These companies are generally non-resident and do not earn income from within the country.
The tax year ends on 31 December, and the annual return on Form IR4 must be filed within three months of year-end, making 31 March of the following year the standard deadline. A company seeking a different balance date must first obtain the Commissioner's approval.
A late-payment penalty of 10% applies to the unpaid amount once the grace period after the due date has passed, and the Tax Administration Act 2012 adds separate late-payment interest on top. Persistent non-compliance can lead to further interest and legal recovery action.
Yes. Where deductions exceed assessable income, the resulting loss carries forward and is set against income in later years until fully used, with any unused balance rolling forward again. A specific year cap is not clearly stated in public sources, so confirm the limit against the consolidated Act.
Targeted incentives exist, most notably for the tourism sector, including import duty exemptions and tax holidays for qualifying tax-resident investors. They depend on conditions such as minimum investment and job creation, and the International Company regime remains the most significant preference for genuinely offshore activity.
