Key Takeaways
- Antigua and Barbuda's treaty network, including the CARICOM multilateral agreement, determines how much relief from double taxation a non-resident can claim.
- Permanent establishment and tie-breaker rules decide where your income is taxed, so structure and residence facts matter before you rely on a treaty.
- Claiming reduced withholding rates requires proving eligibility, and anti-abuse provisions like LOB, the principal-purpose test, and the MLI can deny benefits.
- Coverage gaps in the treaty network may leave parts of your structure exposed, making it worth reviewing which counterparties are actually covered.
Tax Treaties in Antigua and Barbuda: What Foreign Owners Need to Know
Antigua and Barbuda maintains a small network of double taxation agreements, covering 12 jurisdictions, alongside 22 tax information exchange agreements in force. Treaty matters here are administered by the Inland Revenue Department within the Ministry of Finance and Corporate Governance, and the country has moved toward closer alignment with OECD standards, including signing the BEPS Multilateral Convention on 18 June 2025.
These agreements matter most to non-residents drawing passive income from local sources and to regional operators moving between CARICOM states. This article explains what the treaty network covers, how relief works in practice, and where the gaps sit. It is written for foreign owners, investors, and their advisers weighing whether the treaty position supports a particular structure.
The Double Taxation Agreement Network: How Many and With Whom
The treaty network is built around the Caribbean. Nine of the twelve partners are CARICOM neighbours, with only a handful of agreements reaching beyond the region.
| Category | Partners |
|---|---|
| CARICOM members | Barbados, Belize, Dominica, Grenada, Guyana, Jamaica, Saint Kitts and Nevis, Saint Lucia, Saint Vincent and the Grenadines, Trinidad and Tobago |
| Non-regional | Sweden, Switzerland, United Arab Emirates, United Kingdom |
The bilateral income tax treaty with the UAE was signed on 15 January 2017 and entered into force on 24 February 2022, the first such agreement between the two countries. The arrangement with the United Kingdom is far older, signed on 19 December 1947 and in effect locally from 1 January 1968, amended by protocol in March 1968.
Beyond full treaties, the firm sits within a wider exchange-of-information framework. Twenty-two tax information exchange agreements are in force, with partners including Australia, France, Germany, Ireland, the Netherlands, Norway, the United Kingdom, and the United States.
Two further commitments shape how financial data moves. A FATCA intergovernmental agreement with the United States was signed in February 2017, requiring banks to report U.S. account holders, and the CRS Multilateral Competent Authority Agreement was signed on 29 October 2015, with automatic exchange beginning in September 2018.
One point of note for U.S.-connected investors: there is no double tax agreement between this jurisdiction and the United States.

What a Tax Treaty Actually Does for a Non-Resident
A double taxation agreement stops the same income being taxed twice, typically by allocating taxing rights according to where the taxpayer is resident. For a non-resident, the practical value lies in cutting the tax that the source country withholds at the border.
Non-residents are otherwise liable to withholding tax at a statutory rate of 25% on certain locally-sourced income. A treaty can reduce or remove that charge on specific income types, which is why the primary beneficiaries are non-residents holding Antiguan-sourced dividends, interest, or royalties.
The local angle is unusual. Since 2016 the country has applied a zero personal income tax policy, and only locally-sourced income falls under specific tax rules, so the double-taxation risk for most individuals arises in their home country rather than here.
Foreign tax credits are narrow. Relief is generally unavailable unless tax was paid in a British Commonwealth country that grants reciprocal relief, or where a treaty expressly provides for a credit, as the UAE agreement does through the credit method.
The CARICOM Multilateral Double Taxation Agreement
The most consequential instrument in the network is not bilateral. The CARICOM Double Taxation Agreement, signed in 1994, binds ten member states under a single multilateral framework and draws on the 1980 UN Model rather than the OECD Model. Antigua and Barbuda enacted it on 18 February 1998.
Its defining feature is a source-based rule. Article 5 provides that income is taxable only by the member state in which it arises, with limited exceptions, a marked departure from residence-based OECD-model treaties. Self-employed and wage-earning CARICOM nationals are protected from double taxation and are subject to the tax law of their country of origin, not the host state.
For investors, the standout provision is the rate on cross-border dividends.
Dividends paid by a resident of one CARICOM member state to a resident of another are taxed at 0% under the regional agreement, the most practically significant reduced rate in the entire network.
The agreement has not been amended in more than 29 years of operation. You can confirm the ratification dates for each member state through the CARICOM treaty page.

Permanent Establishment and Tie-Breaker Rules Under the Treaties
The regional agreement carries a structural blind spot: it says nothing about permanent establishment. That silence leaves businesses operating across member states uncertain whether their activity creates a taxable presence in a host country.
The bilateral treaties are governed by older language too. Under its provisional MLI position, this jurisdiction reserved out of the convention's permanent establishment anti-avoidance articles, namely Article 12 on commissionnaire arrangements, Article 13 on the specific activity exemption, and Article 14 on the splitting-up of contracts.
It also reserved out of MLI Article 4, the dual-resident entity tie-breaker. The result is that the BEPS-era updates to permanent establishment and dual-residence rules will not modify the existing treaties.
For the UK arrangement, the 1947 and 1968 text continues to govern permanent establishment definitions, a standard that predates the 2017 OECD Model. Older treaty language, rather than recent international updates, decides these questions.
Reduced Withholding Rates and Relief from Double Taxation
Withholding is where treaty relief shows up in cash terms. Income of non-resident companies sourced locally, including dividends, interest, and royalties, is subject to withholding tax, with the statutory rate cited at 25% across most sources. Some sources report an operative rate of 12.5%; the discrepancy should be resolved against the Inland Revenue Department and the Tax Administration and Procedures Act No. 12 of 2018.
The single most useful reduced rate is the CARICOM 0% on dividends paid between residents of member states. Outside the region, relief is patchier and depends on the text of each agreement.
- The UAE treaty eliminates double taxation through the credit method.
- The UK 1947 arrangement covers taxes on income and capital; its specific reduced rates are set by the treaty text itself.
- No public schedule of treaty-reduced rates was retrieved for Sweden, Switzerland, or the UAE beyond the credit-method confirmation.
Where a treaty offers no reduced rate, the domestic withholding rate applies. Foreign tax credits remain limited to Commonwealth partners offering reciprocal relief or to treaty partners that expressly provide for credits.

How to Claim Treaty Benefits and Prove Eligibility
Treaty benefits are administered by the Inland Revenue Department (IRD), which operates within the Ministry of Finance and Corporate Governance under the Commissioner of Inland Revenue. The department administers the Tax Administration and Procedures Act and is the point of contact for tax-residency matters.
Eligibility turns on residency. Residency for tax purposes is defined in the Income Tax Act Cap. 212, and the working standard treats those present in the country for more than 183 days a year as tax residents.
The document that proves residence is a tax residency certificate. Applicants approved under the special tax residency programme receive an official certificate, which a non-resident uses to assert treaty residence to a foreign withholding agent.
No standardised local claim form or refund procedure was found in public sources. As a general matter, the payer in the source country requires a valid residency certificate from the IRD together with the claim form prescribed by that country's own procedure. The IRD portal at ird.gov.ag is the appropriate channel for residency confirmation.
Anti-Abuse Provisions: LOB, Principal-Purpose Test, and the MLI
Treaty abuse rules here are in transition. The country signed the BEPS Multilateral Convention on 18 June 2025, but ratification status should be checked against the OECD MLI database, since the convention is not yet confirmed in force locally.
The provisional position sets several markers. The jurisdiction listed its Covered Tax Agreements under the convention, chose to apply the mandatory binding arbitration provisions in Part VI, and reserved out of the permanent establishment articles and the dual-residence tie-breaker discussed earlier.
The MLI minimum standard requires every party to adopt at least the Principal Purpose Test under Article 7. Full adoption of that test should be confirmed against the final ratified position, and note that the country reserved out of Article 11, the savings clause.
The older instruments contain no modern anti-abuse machinery. Neither the 1947 UK arrangement nor the 1994 CARICOM agreement includes a Limitation on Benefits clause, because both predate the BEPS project, and the regional agreement carries no BEPS-era anti-abuse provisions at all.
Treaty Coverage Gaps and What They Mean for Your Structure
The network's reach is narrow, and the gaps matter more than the coverage for many structures. The absence of any agreement with the United States is the most significant, and there is no totalization agreement either, leaving Americans exposed to potential double social-security taxation.
Major economies sit outside the network entirely. No double tax agreement exists with Canada, Germany, China, India, or any EU member state except through information exchange, so withholding relief is unavailable on income flows to or from those jurisdictions.
- The CARICOM agreement's silence on permanent establishment leaves cross-border regional operators uncertain about taxable presence in a host state.
- The UK arrangement is nearly 80 years old and does not reflect 2017 OECD Model updates, save for whatever the MLI modifies once ratified.
There is a recent compliance history to weigh as well. The country was added to the EU blacklist of non-cooperative jurisdictions in October 2023 and removed in October 2024; that 12-month listing may bear on historical reviews of EU-nexus structures. Independent analysis, including IMF-supported work, has also questioned whether bilateral treaties deliver clear economic benefit to developing states.
Outlook: Treaty Expansion and Reform in Antigua and Barbuda
The direction of travel points toward compliance alignment rather than rapid network growth. The MLI signature in June 2025 is the clearest signal of reform engagement, with the eventual ratification and list of Covered Tax Agreements deciding how many existing treaties are actually modified.
Two further steps reinforce the trend. Removal from the EU non-cooperative list in October 2024 reduced structural risk for EU-connected investors, and accession to the Country-by-Country Reporting Multilateral Competent Authority Agreement on 28 January 2024 extended automatic exchange of those reports.
New bilateral negotiations are another matter. No public data points to active DTA talks with any jurisdiction, and treaty expansion in small Caribbean states tends to move slowly absent bilateral economic pressure or donor programmes. The regional agreement, unchanged since 1994, shows no public proposal for revision, including on permanent establishment or the Principal Purpose Test.
Conclusion
The treaty position rewards regional and a few specific bilateral structures while leaving large economies, the United States foremost among them, outside any relief. For most non-residents the practical double-taxation question arises at home rather than locally, given the zero personal income tax policy, so the value of these agreements is concentrated in reduced withholding on locally-sourced passive income and in the CARICOM zero-rate on dividends. Anyone planning a cross-border structure should confirm the live MLI ratification status and obtain a tax residency certificate before relying on treaty terms. Read each relevant treaty text in full, because reduced rates and anti-abuse language vary widely across this network.

Frequently Asked Questions
The country has double taxation agreements with 12 jurisdictions. Nine are CARICOM neighbours under the regional agreement, with bilateral treaties also covering Sweden, Switzerland, the UAE, and the United Kingdom.
No double tax agreement exists between the two countries, which is the most significant gap for U.S.-connected structures. There is also no totalization agreement, so U.S. nationals may face double social-security taxation, though a FATCA intergovernmental agreement signed in February 2017 governs banking information reporting.
The statutory rate cited across most sources is 25% on locally-sourced income such as dividends, interest, and royalties, while some sources report an operative rate of 12.5%. A treaty can reduce or remove this charge on specific income types, and the discrepancy should be verified with the Inland Revenue Department under the Tax Administration and Procedures Act No. 12 of 2018.
The CARICOM Double Taxation Agreement applies a 0% rate to dividends paid between residents of member states, the most practically significant reduced rate in the network. The agreement also follows a source-based rule, taxing income only in the member state where it arises.
You need a tax residency certificate from the Inland Revenue Department, which proves residence to a foreign withholding agent. Residency for tax purposes follows the Income Tax Act Cap. 212, with the working standard treating presence of more than 183 days a year as residency.
Yes, the country signed the MLI on 18 June 2025, but ratification is not yet confirmed in force and should be checked against the OECD MLI database. It reserved out of the permanent establishment anti-avoidance articles and the dual-residence tie-breaker, so older treaty language continues to govern those points.
