Samoa Tax Residency Guide: 183-Day Rule, DTTs 2026
Samoa determines tax residency based primarily on the 183-day physical presence test. Individuals present in Samoa for 183 days or more in a calendar year are considered tax residents and taxed on worldwide income. Samoa has Double Taxation Treaties with Australia and New Zealand. Here is how tax residency works in 2026.
Tax residency in Samoa is governed by the Income Tax Act 2012 and determines an individual's or company's obligation to pay tax on worldwide versus Samoa-source income. The rules follow international standards. The Ministry of Revenue (MOR) is responsible for determining residency status and issuing Certificates of Residency for treaty purposes.

Real-world example: A digital nomad spends 200 days in Samoa and 165 days in their home country. Since they exceed the 183-day threshold in Samoa, they become a Samoan tax resident and are taxable on worldwide income in Samoa. Their home country may also consider them resident — the applicable DTT is used to resolve dual residency via tie-breaker rules (permanent home, center of vital interests, habitual abode, nationality).

Individual Tax Residency Criteria
- 183-day rule: An individual is resident if present in Samoa for 183 days or more in any 12-month period
- Permanent home: If an individual has a permanent home available in Samoa and spends more than 183 days abroad, they may still be resident if their center of vital interests is in Samoa
- Habitual abode: If no clear permanent home, the habitual abode test applies
Samoan tax residents are taxed on worldwide income. Non-residents are taxed only on Samoa-source income. The tax year is the calendar year.
Corporate Tax Residency
- Place of incorporation: A company is resident in Samoa if it is incorporated under Samoan law
- Place of effective management: A company is also resident if its place of effective management is in Samoa, even if incorporated elsewhere
- Permanent establishment: Non-resident companies with a PE in Samoa are taxed on PE-attributable income
Corporate residency determines whether a company is taxed on worldwide income (resident) or only Samoa-source income (non-resident with PE).
Double Taxation Treaties
Samoa has Double Taxation Treaties with Australia and New Zealand. These treaties follow the OECD Model Convention and provide for:
- Dividends: Reduced withholding tax rates
- Interest: Reduced withholding tax rates
- Royalties: Reduced withholding tax rates
- Business profits: Only taxable in the source country if there is a permanent establishment
- Employment income: Taxable in the work country (subject to the 183-day exemption for short assignments)
Samoa is expanding its treaty network. For countries without a DTT, domestic WHT rates apply (15% on dividends, interest, and royalties).
Certificate of Residency
A Certificate of Tax Residency can be obtained from the MOR to prove Samoan tax residency for treaty purposes. The certificate is typically issued for a specific tax year and states that the individual or company is a resident of Samoa for tax purposes. The application requires: Tax Identification Number (TIN), proof of physical presence (for individuals), and confirmation of tax filings.
Can I be resident in Samoa and another country?
Yes, dual residency is possible. The applicable DTT's tie-breaker clause determines which country has primary taxing rights. The tie-breaker tests are applied in order: permanent home, center of vital interests, habitual abode, and nationality.
What happens if I spend less than 183 days in Samoa?
If you spend fewer than 183 days in Samoa and do not have a permanent home or center of vital interests in Samoa, you are generally a non-resident. You are taxed only on Samoa-source income.
