Caribbean Tax Comparison 2026: Antigua vs Grenada vs Dominica vs St Kitts

A comprehensive Caribbean tax comparison 2026 reveals that all four leading CBI nations — Antigua and Barbuda, Grenada, Dominica, and St Kitts and Nevis — impose zero personal income tax on worldwide earnings, zero capital gains tax, and zero inheritance tax. With citizenship by investment programmes starting from $200,000 and processing in as little as three months, these jurisdictions remain among the most tax-efficient second-citizenship destinations available to UHNW investors.

What Is a Caribbean Tax Comparison and Why Does It Matter in 2026?

A Caribbean tax comparison is a side-by-side analysis of the fiscal regimes across the Caribbean nations that offer citizenship by investment programmes. It evaluates personal income tax, corporate tax, capital gains tax, inheritance and estate tax, property transfer tax, value-added tax (VAT) or consumption levies, and any withholding taxes on dividends, interest, or royalties. For high-net-worth individuals evaluating a second citizenship, understanding these fiscal structures is not a matter of academic interest — it is central to wealth preservation, succession planning, and operational efficiency.

In 2026, this comparison carries particular urgency. The global tax landscape is shifting rapidly. The OECD's Base Erosion and Profit Shifting (BEPS) 2.0 framework and its Pillar Two global minimum corporate tax of 15% are reshaping how multinational enterprises and their beneficial owners think about jurisdictional planning. Meanwhile, the European Union continues to expand its list of non-cooperative tax jurisdictions. Against this backdrop, the Caribbean CBI nations have demonstrated a remarkable ability to maintain competitive tax regimes whilst simultaneously strengthening their transparency and compliance credentials.

For investors who hold or are considering Caribbean citizenship, a thorough understanding of each nation's tax code is essential — not merely for the headline personal income tax rate, but for the entire fiscal ecosystem that surrounds residency, business formation, and wealth transfer.

Personal Income Tax: All Four Jurisdictions Compared

Antigua and Barbuda

Antigua and Barbuda operates a territorial tax system with a notable distinction: there is no personal income tax on income earned outside of Antigua and Barbuda. For individuals who become citizens through the CBI programme but do not reside on the islands or earn local income, their effective personal income tax rate is zero. Even for those who do reside in Antigua, the country abolished personal income tax in 2016, replacing it with a revenue recovery charge and other indirect levies. This means that whether you are a non-resident citizen or a tax-resident individual, Antigua imposes no direct personal income tax.

Grenada

Grenada levies personal income tax on a graduated scale for tax residents, with rates ranging from 15% to 30% on locally sourced income. However — and this is the critical distinction — Grenada does not tax foreign-sourced income. For CBI citizens who maintain their primary tax residence elsewhere and do not generate income within Grenada, the effective personal income tax burden is zero. Grenada's unique position as the only Caribbean CBI nation with a US E-2 Treaty of Commerce and Navigation adds a strategic dimension that extends well beyond its domestic tax code.

Dominica

Dominica employs a graduated personal income tax system for residents, with rates ranging from 15% to 35% on taxable income. As with its Caribbean counterparts, however, Dominica does not tax foreign-sourced income for non-resident citizens. The practical effect is that CBI citizens who are not tax-resident in Dominica — the vast majority of programme participants — face no personal income tax liability. Dominica's appeal, reinforced by its position as the most affordable Caribbean CBI programme at $200,000, lies in this combination of fiscal neutrality and low entry cost.

St Kitts and Nevis

St Kitts and Nevis stands alone among the four in having no personal income tax whatsoever — not on domestic income, not on foreign income, and not for residents or non-residents. The Federation has never imposed a personal income tax. This absolute absence of personal income tax, combined with the prestige and track record of the world's oldest CBI programme (established in 1984), positions St Kitts and Nevis as the benchmark for tax-neutral second citizenship.

Personal Income Tax Comparison — Caribbean CBI Nations 2026

Tax Category	Antigua & Barbuda	Grenada	Dominica	St Kitts & Nevis

VAT / Consumption Tax	15% (ABST)	15% (GCT)	15% (VAT)	17% (VAT)

Corporate Tax, Withholding Tax, and Business Structuring Considerations

Corporate Tax Rates

While the personal tax environment is uniformly favourable across all four nations, corporate taxation is where meaningful differentiation emerges. St Kitts and Nevis applies the highest headline corporate tax rate at 33%, followed by Grenada at 28%, and Antigua and Barbuda and Dominica each at 25%. For investors considering establishing holding companies, trading entities, or international business corporations (IBCs) in their new country of citizenship, this differential can have a material impact on after-tax returns.

It is important to note, however, that headline corporate rates tell only part of the story. Each jurisdiction offers various incentive schemes, free-trade-zone benefits, and sector-specific concessions — particularly for tourism, agriculture, technology, and financial services — that can significantly reduce the effective corporate tax burden. Antigua's special economic zone framework, for instance, can reduce the effective corporate rate well below 25% for qualifying enterprises.

Withholding Taxes

Withholding taxes on cross-border payments of dividends, interest, and royalties are another critical variable. Antigua and Barbuda and St Kitts and Nevis generally do not impose withholding taxes on these outbound payments, making them particularly attractive for holding structures. Grenada and Dominica, by contrast, levy a standard 15% withholding tax on dividends and interest paid to non-residents, though this can be reduced or eliminated under certain double taxation treaties.

Double Taxation Agreements

The breadth and quality of a nation's double taxation agreement (DTA) network is often an overlooked factor in Caribbean tax planning. Grenada and Dominica, as members of the CARICOM treaty framework, benefit from a regional DTA that covers intra-Caribbean transactions. However, none of the four nations maintains the kind of extensive global DTA network found in jurisdictions like Malta, Cyprus, or Singapore. This is rarely a disadvantage for CBI citizens who are using their Caribbean passport primarily for mobility and personal tax efficiency rather than as the domicile for complex corporate structures.

Capital Gains, Inheritance, and Wealth Transfer Taxes

Zero Capital Gains Tax Across the Board

One of the most compelling features of all four Caribbean CBI jurisdictions is the complete absence of capital gains tax. Whether an investor realises gains from the sale of real estate, equities, private business interests, cryptocurrency, or other assets, no capital gains tax is payable in any of these nations. For UHNW individuals managing diversified global portfolios, this represents a significant fiscal advantage — particularly when contrasted with capital gains rates of 20%–37% in the United States, up to 28% in the United Kingdom, or the wealth-eroding solidarity surcharges applied in several European jurisdictions.

No Inheritance or Estate Tax

Succession planning is a cornerstone of wealth preservation for multi-generational families. All four Caribbean CBI nations impose zero inheritance tax, zero estate tax, and zero gift tax. This means that assets can be transferred to the next generation without the fiscal drag that characterises succession in many developed economies. When combined with the ability to include family members — spouses, dependent children, parents, and in some programmes, siblings — in a single CBI application, the Caribbean citizenship proposition becomes a powerful tool for dynastic wealth planning.

Property Transfer Considerations

While there is no capital gains tax on the disposal of property, investors should be aware that property transfer taxes (stamp duty equivalents) do apply in all four jurisdictions at varying rates. In Antigua and Barbuda, the Alien Landholding Licence fee and stamp duty can add 7.5%–10% to the cost of a real estate transaction. Grenada applies a property transfer tax of 5%–15% depending on the buyer's residency status. These are transactional costs rather than recurring taxes, but they merit consideration when evaluating the real estate route of any CBI programme.

CBI Programme Costs and the Full Fiscal Picture

A true Caribbean tax comparison 2026 cannot be divorced from the investment required to obtain citizenship in the first place. The CBI contribution is, in effect, the entry cost to accessing these tax-efficient regimes. Understanding how each programme is priced — and what the total cost of acquisition looks like — is essential for any investor conducting a rational cost-benefit analysis.

CBI Programme Investment Requirements — 2026

Programme	Minimum Investment	Visa-Free Countries	Processing Time	Key Distinction
Antigua & Barbuda	$230,000	144	3–6 months	No personal income tax for residents; 5-day residency requirement
Grenada	$235,000	140	5–7 months	Only CBI with US E-2 treaty access
Dominica	$200,000	136	4–6 months	Most affordable Caribbean CBI; strong due diligence
St Kitts & Nevis	$250,000	148	4–6 months	World's oldest CBI (est. 1984); highest visa-free access

When the CBI investment is viewed as the cost of accessing a lifetime of zero personal income tax, zero capital gains tax, zero inheritance tax, and enhanced global mobility, the value proposition becomes clear. An investor paying $200,000 for Dominica citizenship to eliminate ongoing capital gains exposure on a multi-million-dollar portfolio, for example, may recover the investment cost within a single tax year — depending on their current tax residence and the composition of their assets.

ECCIRA, Global Compliance, and What They Mean for Tax Transparency

The New Caribbean CBI Regulator

The establishment of the Eastern Caribbean CBI Regulatory Authority (ECCIRA) in December 2025, with full operations commencing in April 2026, represents a watershed moment for Caribbean investment migration. Headquartered in Grenada, ECCIRA is tasked with harmonising due diligence standards, processing protocols, and pricing floors across the participating Caribbean CBI nations. While ECCIRA's primary mandate is regulatory rather than fiscal, its existence reinforces the credibility and longevity of the programmes it oversees — which in turn protects the tax-planning value of Caribbean citizenship.

Common Reporting Standard (CRS) and FATCA Compliance

All four jurisdictions are committed signatories to the OECD's Common Reporting Standard (CRS) for the automatic exchange of financial account information. They are also FATCA-compliant with respect to US-person reporting obligations. This means that while the tax rates themselves are extraordinarily favourable, the era of banking secrecy is firmly in the past. Caribbean citizenship is a tool for legal tax optimisation — not evasion. Investors must ensure that their use of a Caribbean passport is fully aligned with the tax reporting obligations of their country of primary tax residence.

EU Considerations

As of 2026, none of the four Caribbean CBI nations appears on the EU's list of non-cooperative tax jurisdictions (the so-called "EU blacklist"). This is significant because inclusion on the blacklist triggers defensive measures from EU member states, including withholding tax surcharges and enhanced scrutiny of transactions involving listed jurisdictions. The Caribbean nations' compliance posture — supported by their CRS commitments, FATCA agreements, and willingness to engage with international regulatory bodies — has thus far protected their standing.

Strategic Scenarios: Which Caribbean Jurisdiction Suits Which Investor?

The Globally Mobile Entrepreneur

For a tech entrepreneur or digital nomad with no fixed base and income sourced from multiple jurisdictions, St Kitts and Nevis offers the cleanest tax profile: zero personal income tax with no territorial distinctions, zero withholding taxes, and the strongest passport (148 visa-free destinations). The premium investment of $250,000 is justified by the programme's unmatched track record and global recognition.

The US-Market-Focused Investor

Grenada is the only rational choice for an investor whose strategic objective includes operating a business in the United States. The E-2 Investor Visa treaty allows Grenadian citizens to live and work in the US by investing in a US-based enterprise — a pathway that is unavailable to citizens of the other three nations. Despite Grenada's domestic income tax rates of 15%–30% and 15% withholding taxes, the non-resident CBI citizen who uses Grenada purely as a passport jurisdiction faces none of these charges on foreign income.

The Cost-Conscious Family Office

For a family seeking the most capital-efficient entry into Caribbean citizenship, Dominica at $200,000 delivers the essential tax benefits — zero foreign income tax, zero capital gains, zero inheritance tax — at the lowest investment threshold. Dominica's programme is also renowned for its rigorous due diligence, which paradoxically enhances the passport's credibility and acceptance in international banking circles.

The Real Estate Investor Seeking Residency Flexibility

Antigua and Barbuda is particularly attractive for investors who wish to spend time in the Caribbean. Its zero personal income tax for residents (not merely non-residents) is a distinctive feature. The five-day minimum residency requirement over the first five years of citizenship is the most relaxed in the region, making it feasible for investors who want the option of eventual physical presence without a punitive tax consequence.

Frequently Asked Questions

Do I Have to Pay Tax in the Caribbean If I Get Citizenship but Live Elsewhere?

No. If you obtain citizenship through a Caribbean CBI programme but do not become a tax resident of that nation — meaning you do not reside there for a sufficient number of days per year and do not earn local income — you will not owe personal income tax, capital gains tax, or any other direct tax in that jurisdiction. Your tax obligations remain with your country of primary tax residence. Caribbean citizenship provides a platform for legal tax planning, not automatic tax exemption from your current country of residence.

Which Caribbean CBI Country Has the Lowest Taxes Overall?

St Kitts and Nevis has the most comprehensively zero-tax personal regime: no personal income tax (for residents or non-residents), no capital gains tax, no inheritance tax, no wealth tax, no gift tax, and no withholding taxes on dividends or interest. Its higher corporate tax rate (33%) is relevant only if you operate a locally incorporated business. For the typical CBI applicant, St Kitts offers the cleanest tax profile.

Can Caribbean Citizenship Help Me Reduce My Tax Burden Legally?

Caribbean citizenship can be a powerful component of a legal tax optimisation strategy, particularly when combined with a change of tax residence. For example, an investor who relocates their tax residence from a high-tax European jurisdiction to a Caribbean nation — or to a third jurisdiction such as the UAE — and holds a Caribbean passport for global mobility, can significantly reduce their personal tax exposure. However, this must be structured carefully and in full compliance with the tax laws of your current country of residence. Mirabello Consultancy works with specialist international tax advisers to ensure every client's strategy is fully compliant.

Are Caribbean CBI Nations Compliant with International Tax Standards?

Yes. All four nations — Antigua and Barbuda, Grenada, Dominica, and St Kitts and Nevis — are signatories to the OECD's Common Reporting Standard (CRS) and have intergovernmental agreements with the United States under FATCA. They participate in the Global Forum on Transparency and Exchange of Information for Tax Purposes and have received broadly positive peer reviews. The establishment of ECCIRA in 2026 further reinforces the region's commitment to regulatory excellence.

Does Grenada's E-2 Treaty Affect My US Tax Obligations?

The E-2 Investor Visa allows Grenadian citizens to live and operate a business in the United States, but it does not exempt them from US taxation. If you reside in the US on an E-2 visa, you will be subject to US federal and state income taxes on your US-sourced income. The E-2 visa is a pathway to the American market, not a tax shelter. It is, however, an extraordinarily valuable commercial tool — and it is available exclusively through Grenada's CBI programme among Caribbean options.

How Do VAT and Consumption Taxes Compare Across the Four Nations?

All four nations levy value-added or goods-and-services taxes on domestic consumption. Antigua and Barbuda applies the Antigua and Barbuda Sales Tax (ABST) at 15%. Grenada levies a General Consumption Tax (GCT) at 15%. Dominica charges VAT at 15%. St Kitts and Nevis applies VAT at 17%. These taxes affect the cost of living and doing business locally but are irrelevant for CBI citizens who reside elsewhere. Essential goods such as food and medicine are typically zero-rated or exempt in all four jurisdictions.

Can I Include My Family in a Caribbean CBI Application?

Yes. All four Caribbean CBI programmes allow the inclusion of family members in a single application. Typically, this includes a spouse, dependent children (up to age 30 in most programmes), dependent parents (typically aged 55 or older), and in some cases, unmarried siblings. The ability to secure citizenship — and its associated tax benefits — for an entire family unit under one application is a significant advantage.
