What You Need to Know About Samoa Corporate Tax

Samoa applies the same 27% corporate tax rate to both resident and non-resident companies, but the scope is different: residents pay on worldwide income while non-residents pay only on Samoa-sourced earnings. Provisional tax is collected in three installments throughout the year, so you need a solid profit forecast from day one. Here is what the rules look like in practice and how to file correctly.

1. What is Corporate Tax?

Corporate tax is a direct tax on the profits of companies operating in Samoa. The Ministry of Customs and Revenue administers corporate tax under the Income Tax Act. The standard corporate tax rate is 27% for both resident and non-resident companies. Resident companies are taxed on their worldwide income, while non-resident companies are taxed only on income derived from Samoa sources.

2. Who does it apply to?

This usually applies to:

Companies incorporated in Samoa
Foreign companies earning income from Samoa sources
Branches of overseas companies operating in Samoa
Trusts and other entities with taxable income
Non-resident companies with a permanent establishment in Samoa
Public bodies and statutory corporations earning taxable income

3. Why does it matter?

Understanding corporate tax helps you:

Stay compliant with tax laws
Avoid penalties and late fees
Keep proper records
File and pay correctly
Plan your cash flow better

4. How does it work?

Here's the basic process:

Calculate your company's total income from all sources during the tax year
Deduct all allowable business expenses and depreciation
Arrive at your taxable income
Apply the 27% corporate tax rate
Calculate any tax credits (foreign tax credits, withholding tax credits)
Pay provisional tax in installments during the year
File your annual corporate income tax return with the Ministry of Customs and Revenue
Pay any remaining tax or claim a refund if overpaid

5. What forms are involved?

Corporate Income Tax Return - Annual return filed with the Ministry of Customs and Revenue
Provisional Tax Assessment - Notice of estimated tax payable in installments
Financial Statements - Audited or reviewed accounts submitted with the return
Tax Computation Schedule - Detailed calculation of taxable income
Withholding Tax Return - Filed when making payments subject to withholding tax

6. What information do you need?

Before handling corporate tax, make sure you have:

Company TIN (Tax Identification Number)
Audited or reviewed financial statements
Detailed records of all income and expenses
Depreciation schedules for fixed assets
Records of tax losses carried forward
Withholding tax certificates received
Details of related-party transactions
Records of any tax exemptions or incentives claimed

7. Important deadlines

Tax year: Generally the calendar year or an approved substitute period
Provisional tax installments: Payable in three installments during the year
Annual return filing: Within the timeframe specified by the Ministry (typically within 4-5 months after year-end)
Payment of balance tax: Due with the filing of the annual return
Year-end requirements: Prepare financial statements, reconcile provisional tax, file the annual return

8. Common mistakes to avoid

Not paying provisional tax installments on time
Underestimating provisional tax and facing a large balance at year-end
Claiming deductions for private or non-business expenses
Not maintaining proper records of related-party transactions
Forgetting to claim available tax credits
Not carrying forward tax losses correctly
Missing the annual return filing deadline

9. Simple example

Your company in Samoa earns WST 500,000 in revenue and has WST 350,000 in allowable expenses.

Taxable income: WST 500,000 - WST 350,000 = WST 150,000
Corporate tax at 27%: WST 150,000 x 27% = WST 40,500

You pay provisional tax in three installments during the year:

First installment: WST 13,500
Second installment: WST 13,500
Third installment: WST 13,500
Total provisional: WST 40,500

If your actual tax differs from your provisional payments, you either pay the balance or receive a refund.
