# Caribbean IBC Banking: How to Open a Business Account in 2026 Opening a Caribbean IBC business account in 2026 means passing full AML and KYC checks, documenting source of funds, and demonstrating genuine economic substance, then completing setup fees of roughly $1,500 to $5,000 over four to twelve weeks. Accounts are CRS and FATCA reportable. This is general information, not tax or legal advice. ### Key Takeaways - Account opening typically takes **4-12 weeks**; a complete documentation package is the single biggest factor in approval. - The old **0% IBC regimes are closed** in all five Eastern Caribbean CBI countries (repealed or ended 2018-2022). Companies are taxed where they are managed and controlled. - Banks look for a **genuine business purpose**, verifiable source of funds and, where relevant, local substance. - Caribbean citizenship can make banking in the region easier, but it is **not a shortcut past due diligence** and does not by itself make you tax resident. - All five countries take part in the OECD **Common Reporting Standard**: account information is exchanged with your country of tax residence. - Multi-currency accounts in USD, EUR and GBP are widely available from regional and international banks. ## Caribbean IBC Banking: How to Open a Business Account in 2026 Opening a business bank account for a Caribbean company in 2026 usually takes **four to twelve weeks** and succeeds or fails on one thing: documentation. The company itself has changed. Between 2018 and 2022 the five Caribbean citizenship by investment countries closed their tax-exempt International Business Company (IBC) regimes, so a Caribbean company is now taxed where it is managed and controlled, and banks expect a clear business purpose, substance and source of funds. This guide explains what still works, what banks ask for, and how Caribbean citizenship fits in. ### Key Takeaways - Account opening typically takes **4-12 weeks**; a complete documentation package is the single biggest factor in approval. - The old **0% IBC regimes are closed** in all five Eastern Caribbean CBI countries (repealed or ended 2018-2022).

An International Business Company was a company formed under special offshore legislation for business conducted outside the country of incorporation, usually exempt from local tax. Under pressure from the OECD and the European Union's work on harmful tax practices, the five Eastern Caribbean citizenship by investment countries ended these regimes: | Country | What happened to the IBC regime | Company tax today | | --- | --- | --- | | Grenada | International Companies Act repealed from 31 December 2018 | 28% on worldwide income for resident companies | | Dominica | International Business Companies Act repealed from 1 January 2022 | 25% on worldwide income for resident companies | | Antigua & Barbuda | Tax exemption repealed from 31 December 2018 | 25% on worldwide income if managed and controlled there | | St. Kitts & Nevis | Exemption closed to entities formed after 31 December 2018 | 25% on worldwide income if managed and controlled in the Federation | | St. Lucia | IBCs still exist, without the old exemption | 30% on Saint Lucia-source income only | Existing companies in Antigua and Barbuda, St. Kitts and Nevis and St. Lucia were grandfathered only until 30 June 2021. The full background is in our guide to [Caribbean citizenship and company structures](https://www.mirabelloconsultancy.com/blog/caribbean-citizenship-ibc-business), and our [Caribbean company formation guide](https://www.mirabelloconsultancy.com/blog/caribbean-ibc-formation-guide-best-island-2026) compares the islands for new companies. ## Why Banking Still Matters A company still needs a bank, and Caribbean companies still have legitimate uses: holding investments or property, trading, or running a business that is genuinely managed in the region. Banks, both regional and their international correspondents, carry out extensive due diligence before onboarding a company. That is not a barrier for a real business; it is a filter, and the way through it is a well-prepared file. ## Step-by-Step: How to Open a Business Account ### Step 1: Decide Where the Company Will Be Managed (Before Forming It) Where the company is managed and controlled now decides where it pays tax, and banks will ask about it. Settle this with a tax adviser first, then choose the type of company (an ordinary company, a [Nevis LLC](https://www.mirabelloconsultancy.com/blog/nevis-llc-asset-protection-business-structure-2026) or another vehicle) and appoint directors and a registered agent. ### Step 2: Prepare the Documentation Package (Weeks 1-4) This is where most applications succeed or fail. Banks typically ask for: - Certificate of incorporation and constitutional documents (certified) - Certificate of good standing, if the company is not newly formed - Board resolution authorising the account and naming signatories - Registers of directors and shareholders, certified by the registered agent - Beneficial ownership declaration identifying every ultimate beneficial owner - Identification for all directors, signatories and beneficial owners: passport copies, proof of address, professional references - A business plan or activity summary: what the company does, expected transaction volumes, source of funds and markets - Bank reference letters from existing banking relationships - Source of funds and source of wealth evidence: accounts, tax returns, sale agreements, investment records - The bank's own KYC and anti-money laundering questionnaire ### Step 3: Due Diligence (Weeks 4-8) The bank's compliance team reviews the file, runs background checks on international databases and may ask for more information. For politically exposed persons, enhanced due diligence can add several weeks. ### Step 4: Activation and First Deposit (Weeks 8-12) Once approved, the bank issues account details and may ask for a minimum opening balance, which varies by bank. Online banking is standard, and most banks offer USD, EUR and GBP accounts. Not sure which programme is right for you?

A company that is in fact run from your home country will usually be taxed there, whatever its place of registration. Many Caribbean jurisdictions also adopted economic substance rules for certain activities when their exemptions ended. ### Common Reporting Standard and Anti-Money Laundering All five Eastern Caribbean CBI countries participate in the OECD's [Common Reporting Standard](https://www.oecd.org/tax/automatic-exchange/). Banks report balances, interest, dividends and sale proceeds to the tax authority of the account holder's country of tax residence. Anti-money laundering checks follow the standards of the [Financial Action Task Force](https://www.fatf-gafi.org/). A Caribbean account is a tool for international business and diversification, not for secrecy. ### ECCIRA The Eastern Caribbean Citizenship by Investment Regulatory Authority (ECCIRA), established in December 2025 and expected to begin operating later in 2026, is set to introduce a supranational regulatory framework overseeing all five Eastern Caribbean CBI programmes; none of its measures is yet in force. Common due diligence standards for citizenship applicants should, over time, also support the region's credibility with international correspondent banks. ## Where Caribbean Citizenship Helps A Caribbean passport does not exempt anyone from due diligence: the applicant has already passed government due diligence to obtain it, and the bank will still run its own. In practice, though, citizenship can help with banking in the region, particularly when combined with real ties such as a home or business there, because the bank is dealing with a national rather than a non-resident with no connection to the country. It is one reason some clients pair a company with [St. Kitts and Nevis](https://www.mirabelloconsultancy.com/immigration/citizenship-by-investment-in-st-kitts-nevis), [Antigua and Barbuda](https://www.mirabelloconsultancy.com/immigration/antigua-and-barbuda-citizenship-by-investment) or [Dominica](https://www.mirabelloconsultancy.com/immigration/dominica-citizenship-by-investment) citizenship. Citizenship is not tax residence. Your personal tax position still follows where you actually live, and the company's follows where it is managed. ### Grenada and the US E-2 Visa [Grenada](https://www.mirabelloconsultancy.com/immigration/grenada-citizenship-by-investment) is the only Caribbean CBI country whose nationals can apply for the US E-2 Treaty Investor visa. The old idea of a "Grenada IBC parent" no longer applies: the International Companies Act was repealed from 31 December 2018. What matters for the E-2 is that the US business is at least 50% owned by Grenadian nationals, and since 23 December 2022 a citizen by investment must first have been domiciled in Grenada for three continuous years. Our [Grenada E-2 strategy guide](https://www.mirabelloconsultancy.com/blog/grenada-e2-visa-ibc-strategy-us-business-access-2026) explains the route in full. ## Common Pitfalls and How to Avoid Them ### Insufficient Source of Funds Evidence The most common reason for rejection. Banks need a clear, verifiable trail from the origin of the wealth to the opening deposit and the expected activity. Bank statements alone are not enough; provide the contracts, letters and certificates that show how the money was earned. ### A Vague Business Plan A plan that cannot explain the company's purpose, markets, transaction volumes and revenue model will raise compliance concerns. It need not be long, but it must be specific and consistent with the declared source of funds. ### Planning Around a Tax Regime That No Longer Exists Telling a bank that a company exists to be "tax-free" is now a red flag in itself, and in the five CBI countries it is no longer true. Present the real commercial reason for the company and its actual tax position. ### Choosing the Wrong Bank Banks differ widely in their appetite for international companies, and that appetite changes with correspondent banking pressure. An adviser who knows the current position of each bank saves months. ## What to Budget | Cost Category | Low Estimate (USD) | High Estimate (USD) | Notes | | --- | --- | --- | --- | | Company formation | $1,000 | $3,500 | Varies by jurisdiction and complexity | | Registered agent (annual) | $800 | $2,000 | Required in all jurisdictions | | Bank account setup | $500 | $2,500 | Includes compliance processing | | Legal, tax and advisory fees | $2,000 | $7,500 | Documentation, tax advice, application support | | Local management and accounts | $1,500 | $5,000+ | Only if the company is genuinely managed in the Caribbean | | Annual banking fees | $600 | $2,400 | Maintenance, transfers, reporting | Banks may also require a minimum balance. If you are combining a company with citizenship by investment, the citizenship investment (from $200,000 in Dominica) is a separate decision, and should be made on the merits of the passport, not on tax promises about companies.

Frequently asked questions ## Frequently asked questions ### Do Caribbean IBCs Still Get 0% Tax? No, not in the five Caribbean citizenship by investment countries. Grenada and Dominica repealed their international company laws, and Antigua and Barbuda, St. Kitts and Nevis and St. Lucia removed the tax exemption, with existing companies grandfathered only until 30 June 2021. A company is now taxed where it is managed and controlled. ### Can I Open a Caribbean Business Account Without Citizenship? Yes. Citizenship is not a legal requirement. It can make banking in the region easier, especially with real ties to the country, but the decisive factors are a clear business purpose, complete documentation and a verifiable source of funds. ### How Long Does It Take to Open the Account? Typically four to twelve weeks, depending on the bank, the completeness of the file and the profile of the owners. Politically exposed persons and complex ownership structures take longer. ### Which Caribbean Jurisdiction Is Best for a Company in 2026? It depends on where the company will really be managed, what it will do and which banks it needs. Because tax now follows management and control, the right answer starts with your own residence and business plan. We assess this case by case with independent tax advisers. ### Are Caribbean Bank Accounts Reported Under CRS? Yes. All five Eastern Caribbean CBI countries participate in the OECD Common Reporting Standard. Banks report account information to the tax authority of the account holder's country of tax residence, so full compliance at home is essential. ### Can a Grenada Company Help Me Get a US E-2 Visa? Not in the old way. Grenada's International Companies Act was repealed from 31 December 2018. For the E-2, the US business must be at least 50% owned by Grenadian nationals, and a citizen by investment must first have been domiciled in Grenada for three continuous years. ### How Do I Start with Mirabello Consultancy?
