Antigua & Barbuda Tax Residency Guide: 183-Day Rule, Territorial System 2026

Q: Can I be resident in Antigua and another country?

Yes. Dual residency is possible. The applicable DTT's tie-breaker clause determines primary taxing rights. Antigua's territorial system benefits dual residents.

Q: What happens if I spend less than 183 days in Antigua?

You are generally a non-resident and taxed only on Antigua-source income at applicable rates.

Antigua and Barbuda determines tax residency based primarily on the 183-day physical presence test. Individuals present for 183 days or more in a calendar year are considered tax residents. However, Antigua operates a territorial tax system — residents are taxed only on Antigua-source income, not worldwide income. Here is how tax residency works in 2026.

Tax residency in Antigua and Barbuda is governed by the Income Tax Act and determines an individual's or company's obligation to pay tax. The territorial system means that even tax residents are not taxed on foreign-source income, making Antigua highly attractive for internationally mobile individuals. The Inland Revenue Department (IRD) is responsible for determining residency status and issuing Certificates of Residency. Personal income tax →

Real-world example: A digital nomad spends 210 days in Antigua and 155 days in their home country. Since they exceed the 183-day threshold, they become an Antigua tax resident. However, because Antigua uses a territorial system, their foreign-source income (e.g., foreign salary, overseas investments) is not taxed in Antigua. Only income earned from Antigua sources (e.g., local employment, local business) is subject to tax. This is a major advantage over countries that tax worldwide income.

Individual Tax Residency Criteria

183-day rule: An individual is resident if present in Antigua and Barbuda for 183 days or more in a calendar year
Permanent home: Having a permanent home available in Antigua may indicate residency even with fewer than 183 days
Habitual abode: Pattern of presence and intention to reside can establish residency
Citizenship by Investment: CIP participants who meet the physical presence test become tax residents

Antigua tax residents are taxed only on Antigua-source income (territorial system). Non-residents are taxed only on Antigua-source income as well, but potentially under different withholding rules. The tax year is the calendar year.

Corporate Tax Residency

Place of incorporation: A company is resident in Antigua if it is incorporated under Antiguan law
Place of effective management: A company is also resident if its central management and control is exercised in Antigua
Permanent establishment: Non-resident companies with a PE in Antigua are taxed on PE-attributable income

Corporate residency determines CIT obligations. Resident companies are taxed on Antigua-source income. Non-resident companies with a PE are taxed only on income attributable to the PE.

Double Taxation Treaties

Antigua and Barbuda has a limited Double Taxation Treaty network, primarily within CARICOM. Key treaty partners include:

CARICOM members: Trinidad and Tobago, Barbados, Jamaica, Guyana, Belize, and other CARICOM states (CARICOM Double Taxation Agreement)
Other: A limited number of bilateral treaties with select countries

Antigua has fewer DTTs than many other jurisdictions. The territorial system reduces the need for treaties since foreign-source income is not taxed. Treaties generally follow the OECD Model and provide for reduced withholding rates and dispute resolution.

Certificate of Residency

A Certificate of Tax Residency can be obtained from the IRD to prove Antiguan tax residency for treaty purposes. The certificate is typically issued for a specific tax year. The application requires: tax identification number (TIN), proof of physical presence, and confirmation of tax filings. Processing time is typically 5-15 business days.

Can I be resident in Antigua and another country?

Yes, dual residency is possible. The applicable DTT's tie-breaker clause determines which country has primary taxing rights. Given Antigua's territorial system, dual residents typically benefit from not being taxed on foreign income in Antigua.

What happens if I spend less than 183 days in Antigua?

If you spend fewer than 183 days and do not have a permanent home or center of vital interests in Antigua, you are generally a non-resident. You are taxed only on Antigua-source income at applicable rates.
