Key Takeaways
- Foreign-owned companies in scope must register with the Inland Revenue Department and file a corporate income tax annual return.
- Filing involves set deadlines and frequency, with monthly instalments forming part of how tax due is paid.
- Late, incorrect, or missing returns carry penalties, making accurate reporting and timely submission important.
- Special cases and exemptions can apply to non-resident companies and IBCs, so each entity should confirm its own obligations.
Understanding Corporate Income Tax Filing in Antigua and Barbuda
Tax filing in Antigua and Barbuda centres on the Corporate Income Tax Annual Return, the document every company subject to tax must lodge with the Inland Revenue Department after each fiscal year. The obligation does apply, and it rests on the Income Tax Act, Cap. 212, with administration and enforcement handled under the Tax Administration and Procedures Act No. 12 of 2018. The Inland Revenue Department sits within the Ministry of Finance and Corporate Governance and is led by the Commissioner of Inland Revenue.
This article explains who files, how to register, what the return contains, when it is due, how tax is paid, and the penalties that follow a missed obligation. It speaks most directly to foreign owners of resident companies, branches of foreign firms, and holders of International Business Corporations weighing whether the return reaches them at all.
Who Must File the Corporate Income Tax Annual Return
Every company registered locally carries responsibility for filing returns and remitting tax. Residence drives the scope of that liability.
A company counts as resident if it is incorporated, registered as an external company, or centrally managed and controlled within the jurisdiction. A resident entity is taxed on worldwide income; a non-resident is taxed only on income derived or sourced inside the country.
Non-residents, whether people or companies, owe tax where they have local income sources. With no Antigua-sourced income, a non-resident has no liability and nothing to file.
Branches of foreign companies fall under the standard 25% rate on their Antigua-sourced profits, the same rate domestic firms pay. International Business Corporations sit apart, with a conditional exemption examined later in this article.
If you are not resident but owe tax, you must nominate a person resident in Antigua and Barbuda to act as your agent for compliance purposes. This requirement under TAPA means a foreign owner cannot deal with the tax authority entirely from abroad.

Tax Registration with the Inland Revenue Department
Registration with the IRD comes first. After incorporation, a business applies for a Tax Identification Number, the reference that links every later return and payment to your entity.
The TIN application uses Form F14, available through the government forms portal. Registration covers corporate tax on resident companies' worldwide income and feeds into indirect tax once turnover crosses the relevant line.
For the Antigua and Barbuda Sales Tax, registration becomes mandatory when annual sales of goods or services are expected to exceed EC$300,000. That threshold matters mainly to firms trading inside the country rather than purely offshore structures.
TIN registration is an administrative step. No specific government fee for corporate income tax registration appears in official sources; treat it as a filing rather than a charge.
Where you appoint an agent to act for tax purposes, that person becomes your representative under TAPA, and you must notify the Commissioner of the appointment. Should a representative become unable to serve, you have 30 days to advise the Commissioner in writing of the replacement.
The Corporate Income Tax Annual Return Explained
The return reports a company's results for its fiscal year and settles the tax charge for that period. It is filed with and assessed by the IRD, and it must reach the Department within three months of the fiscal year end.
The standard corporate rate is 25%. Qualifying banks are taxed at 22.5%, while insurance, oil, and telecommunications companies face a 10% rate. Companies incorporated locally are charged on worldwide income.
To prepare the return, the IRD publishes the Corporation Income Tax Return Preparation Guide, issued as Form F01 on the forms portal. The guide walks through the income, expense, and tax computation that the return requires.
Payments to non-residents bring a separate strand. Withholding tax under Sections 39 and 40 of the Income Tax Act applies at 15% for CARICOM-qualifying rates, 25% for companies without a reduced rate, and 20% for individuals without a reduced rate, declared monthly on the WO2 form by the 15th of the following month.
Ongoing Compliance in Antigua and Barbuda
Keep your Antigua and Barbuda entity compliant with filings, returns, and statutory obligations.
What Must Be Reported on the Return
The annual return captures both governance and financial detail. Companies disclose directors, shareholders, and the financial results for the year.
Drawing on the Form F01 guide, the return sets out:
- Gross income of the business
- Total expenses for the year
- Net chargeable income
- Wear-and-tear (depreciation) schedules, showing asset category, current value, acquisition cost, and disposals
- Total tax to pay
Where you have paid non-residents, Appendix B2 of the return provides a worksheet for withholding tax, requiring the amounts paid, the rates applied, and the tax payable under Sections 39 and 40. The Appendix B2 worksheet is published in full on the government forms portal.
Tax losses can generally be carried forward to reduce future taxable profits. All financial statements, invoices, books of original entry, and correspondence with the IRD must be in English.
Whether audited accounts must be attached to the return, rather than retained, is not confirmed in public sources. As a general principle, TAPA requires that underlying records stay available for audit on the Department's request.
Filing Deadlines, Frequency, and Monthly Instalments
The Corporate Income Tax Annual Return is due within three months of the fiscal year end. For a company on a calendar year, that fixes the deadline at 31 March.
Payment does not wait until the return is filed. Tax is paid in monthly instalments set by the prior year's assessment, each instalment falling due on the last day of every complete month of the taxation year.
| Obligation | Timing |
|---|---|
| Annual return filing | Within 3 months of fiscal year end (31 March for calendar-year firms) |
| Monthly instalments | Last day of each complete month of the taxation year |
| Final balance of tax | Within 3 months of the year end |
| Withholding tax declaration (WO2) | 15th of the month following payment |
Corporate tax is paid in Eastern Caribbean Dollars. No published automatic extension mechanism for the annual return deadline was found; the Commissioner holds discretion over assessment and collection under TAPA, but plan around the standard deadline rather than relying on relief.

Paying the Tax Due
Returns and payments both run through the IRD. The Department lists several banking channels for settling tax.
- ACB online
- ECAB MORE Banking
- FCIB online
- Wire transfer, using details published on the IRD website
The Eastern Caribbean Dollar is pegged at US$1 = EC$2.70, so a foreign owner can budget the liability in hard currency with little exchange uncertainty. No government filing fee separate from the tax itself was identified for submitting the return.
One point deserves attention for anyone considering an objection. The Commissioner may enforce collection of tax before any objection or appeal is determined, so a disputed assessment does not, by itself, suspend the duty to pay.
E-Filing and the IRD Portal
The IRD's primary public site is ird.gov.ag, hosting forms, guides, and payment instructions. The same material is mirrored on the Government of Antigua and Barbuda site at ab.gov.ag.
Tax forms live on the forms portal at forms.gov.ag, including the Form F01 preparation guide, the Appendix B2 withholding worksheet, and registration forms in PDF format. These are downloadable documents rather than an interactive filing system.
No dedicated online portal built specifically for submitting the Corporate Income Tax Annual Return was identified in available sources. The IRD publishes PDF forms and accepts payment through the banking channels above; confirm whether electronic submission has become available by checking directly with the IRD.
Incorporation is a separate track. Company formation can be filed manually or through ABIPCO's e-filing system, but ABIPCO handles incorporation, not tax returns, which always go to the IRD.
Legal Basis: The Income Tax Act and TAPA
Two statutes shape the obligation. The Income Tax Act, Cap. 212, originally enacted in 1945 and amended since, governs the charge, computation, and assessment of corporate income tax, and is cited across the IRD's return forms.
Sections 39 and 40 of that Act set the withholding regime on payments to non-residents. Procedure and enforcement come from the Tax Administration and Procedures Act No. 12 of 2018, which consolidated recovery and enforcement provisions into a single law and created an appeals division for taxpayers.
The IBC framework comes from the International Business Corporations Act of 1982. A later reform changed its tax treatment materially: the Miscellaneous Amendments Act deleted articles 270–281, which had granted the blanket exemption, so that an IBC tax resident in the jurisdiction or carrying on a permanent establishment there now falls within the 25% charge.
Two TAPA provisions reach foreign owners personally. Failing to create, maintain, or retain required records draws a penalty of EC$1,000, and a director can be jointly and severally liable for unpaid company tax where they held office at any time in the six months before the failure to pay.
Penalties for Late, Incorrect, or Non-Filing
Missing a deadline is costly, and the charges compound month by month. The structure separates late filing from late payment.
| Default | Penalty |
|---|---|
| Late filing of the annual return | EC$500 or 5% of tax due, whichever is greater, per month outstanding |
| Late payment of tax | 20% of unpaid tax, plus 1% interest per complete month outstanding |
| Late filing of withholding return (WO2) | 5% penalty, minimum EC$500 |
| Late payment of withholding tax (beyond 14 days) | 10% penalty plus 1% interest per month |
| Failure to maintain records | EC$1,000 |
Enforcement under TAPA reaches well beyond financial penalties. The IRD may recover unpaid tax through wage garnishment, asset seizure, or liens on property.
The reach extends to movement. The Commissioner may serve an order on police and immigration officers at ports of entry concerning persons with outstanding tax liabilities, which can affect individuals connected to a defaulting company.
No strike-off mechanism tied specifically to non-filing of tax returns was identified; strike-off is a Companies Act remedy that operates separately. In practice, IRD enforcement runs in parallel with a company's status on the registry.
Exemptions and Special Cases for Non-Resident Companies and IBCs
The treatment of an International Business Corporation depends entirely on where it operates and where it is managed. This is the area most likely to surprise a foreign owner who relied on older descriptions of the regime.
Under the IBC Act, a corporation that conducts business exclusively outside Antigua and Barbuda has long enjoyed exemption from corporate income tax, framed as a 50-year exemption spanning dividends, interest, and royalties involving foreign parties, with no withholding on such payments to non-residents. Where the company trades only offshore, there is no requirement to file audited accounts or tax returns with the authorities.
The reform changed the boundary of that benefit. After the Miscellaneous Amendments Act removed articles 270–281, an IBC that is tax resident in the jurisdiction, or that constitutes a permanent establishment there, is taxed on profits at 25%.
The dividing line is effective management. An IBC stays outside Antiguan tax as long as its effective place of management sits abroad and it operates no permanent establishment locally.
IBCs face activity limits that protect their offshore character:
- No trading within Antigua and Barbuda
- No ownership of local real estate
- No public offering of shares
- No banking, insurance, fund management, or collective investment activity
Crossing those limits risks the exemption. Even so, an IBC must keep financial records reflecting its position and observe AML rules, a point covered in its own dedicated article.
Non-resident ordinary companies are treated differently from IBCs. Where such an entity earns Antigua-sourced income, it files the Corporate Income Tax Annual Return, pays 25% on that income, and meets all TAPA duties, including the resident-agent requirement.
The wider standing of the jurisdiction has improved. The Council of the European Union removed Antigua and Barbuda from its list of non-cooperative tax jurisdictions in October 2024, and the country maintains double taxation treaties with 12 jurisdictions alongside a broad network of tax information exchange agreements and participation in the OECD Common Reporting Standard.
Conclusion
The decisive question for a foreign owner is residence, not nationality. A resident company or a local branch with Antigua-sourced income files the Corporate Income Tax Annual Return at 25% within three months of year end, pays in monthly instalments, and faces real enforcement if it slips; a genuinely offshore IBC managed from abroad files nothing here.
Before you assume the exemption protects you, confirm where your IBC is effectively managed and whether it has created a permanent establishment, because that single fact decides whether the 25% charge applies.

Frequently Asked Questions
An IBC that conducts business exclusively outside the jurisdiction and is not tax resident there has no requirement to file a tax return or audited accounts. If the IBC becomes tax resident or operates a permanent establishment locally, it is taxed at 25% and falls within the standard filing duties.
The return must reach the Inland Revenue Department within three months of the fiscal year end, which falls on 31 March for a company using the calendar year. The final balance of tax is due in the same three-month window, on top of the monthly instalments paid through the year.
Late filing of the return draws EC$500 or 5% of the tax due, whichever is greater, for each month it stays outstanding. Late payment adds a 20% penalty on the unpaid tax plus 1% interest for every complete month the balance remains, and the IRD can enforce collection through garnishment, asset seizure, or liens.
Yes. A person who is not resident but liable to tax must nominate a resident agent for compliance, and that agent must be notified to the Commissioner as the taxpayer's representative under TAPA. If the representative can no longer act, you have 30 days to advise the Commissioner of a replacement in writing.
Payments to non-residents are reported on the WO2 monthly declaration, due by the 15th of the month after payment, with rates of 15% for CARICOM-qualifying recipients, 25% for non-qualifying companies, and 20% for non-qualifying individuals. The same amounts are summarised on Appendix B2 of the annual return under Sections 39 and 40 of the Income Tax Act.
The IRD publishes its forms and guides as downloadable PDFs and accepts payment through online banking channels such as ACB online, ECAB MORE Banking, and FCIB online, plus wire transfer. No dedicated electronic portal built solely for submitting the Corporate Income Tax Annual Return was identified, so confirm current submission options directly with the IRD.
