Key Takeaways
- Foreign-owned companies meeting the filing criteria must submit a corporation tax return in Barbados, with registration handled through a TAMIS account.
- Resident and non-resident companies report different scopes of income, so confirming your status determines what must be declared on the return.
- Filing deadlines are set according to your company's fiscal year-end, and returns are submitted online through TAMIS to the Barbados Revenue Authority.
- Late, missing, or incorrect filings can trigger penalties, making accurate reporting and timely payment of any tax due essential for non-resident owners.
Understanding the Corporation Tax Return in Barbados
The Corporation Tax Return is the annual income tax filing every company doing business in Barbados must submit to the Barbados Revenue Authority. This obligation does apply, and it begins from the date of incorporation, regardless of whether the business earns a profit. The governing law is the Income Tax Act, Cap. 73, supported by the Income Tax Act and its 2024 amendments, with administration handled through the online TAMIS platform.
This article explains who must file, how to register, what income and schedules the return covers, when it is due, how payment works, and what happens if a filing is late or wrong. It is written for foreign owners and their advisers responsible for keeping a Barbados company compliant from outside the country.
Which Companies Must File a Corporation Tax Return
Any company that has carried on business is required to file Corporation Tax Returns for every income year. The duty runs from incorporation, not from first profit, so a dormant or pre-revenue entity still files.
Resident companies are taxed on worldwide income. A non-resident firm is taxed only on income arising from sources and operations within the jurisdiction, and there is no tax on capital.
If your business no longer trades, filing alone does not end the obligation. To stop the annual return cleanly, you must dissolve the company by filing Articles of Dissolution with the Registrar of Companies, which requires the entity to be in good standing under the Companies Act, Cap. 308.
A company that falls out of good standing by breaching the Companies Act can be struck off the Companies Register. Filing returns is part of staying in good standing.

Tax Registration and Obtaining a TAMIS Account
Before you can file anything, the company needs a Tax Identification Number. Registration happens through TAMIS, the online system the revenue authority launched in June 2018, which issues a unique 13-digit TIN used to file returns, make payments, and receive refunds.
When registering a company, the authorised person or agent selects "I am an authorised person or agent registering a new non-individual entity" on the Registration Type page, and enters the entity's CAIPO registration date as the commencement date. Have a valid email address you can access and a scanned copy of valid ID ready before you start.
After signing up as a web user and submitting the tax details, a confirmation email follows once the application is verified. If the system returns an REG reference number rather than an immediate TIN, an officer must vet the application first before the number is issued.
| Item | Detail |
|---|---|
| Portal | https://tamis.bra.gov.bb |
| Identifier issued | 13-digit Taxpayer Identification Number (TIN) |
| Commencement date to enter | The entity's CAIPO registration date |
| Support line | 535-ETAX / 535-3829, 7:30 am to 8:30 pm |
Resident and Non-Resident Companies: Scope of Income Reported
What you report turns on residence. A resident company declares income from all sources, inside and outside the country, less expenses incurred to produce assessable income within a fiscal period that cannot exceed 53 weeks.
A non-resident company reports a narrower base: only income derived from sources and operations conducted locally. Capital gains fall outside the net entirely, since there is no tax on capital.
Rates effective from income year 2024 set the standard corporate rate at 9%, with 5.5% for specified small companies and 4.5% on qualifying intellectual property income by election. Separately, a Qualified Domestic Minimum Top-Up Tax reaches resident members of multinational groups with annual consolidated revenue of EUR 750 million or more, lifting their effective rate to the global minimum of 15%.
Ongoing Compliance in Barbados
Keep your Barbados entity compliant with filings, returns, and statutory obligations.
What Must Be Reported on the Corporation Tax Return
The return is an annual self-assessment of the fiscal period's assessable income, allowable deductions, capital allowances and wear and tear, and the net tax owed. A Capital Allowance and Wear & Tear Schedule must accompany every filing.
Loss treatment changed with effect from income year 2025: tax losses may be carried forward only for five income years after the year in which the loss arose. Several credits can reduce the liability if your business qualifies.
- A jobs credit, for companies and permanent establishments in specified sectors with eligible payroll expenditure incurred after 1 January 2024, on a sliding scale of 25% to 100% of that expenditure.
- An R&D credit of 50% of eligible expenditure, available to any entity carrying on qualifying research and development, usable against other tax liabilities for four years.
- A patent box election taxing qualifying intellectual property income, including software copyright and patents, at 4.5%.
Multinational groups at or above the EUR 750 million revenue threshold also address top-up tax under the Corporation Top-Up Tax Act, 2024, which is a separate levy filed alongside the standard return. The revenue authority issued a revised 2024 return inside TAMIS, so confirm you are using the updated version and delete any saved draft of the earlier one before you begin.
The authority recommends the Firefox browser and advises clearing your browser cache before filing. Deleting old draft returns avoids submitting on a superseded form.
Filing Deadlines Based on Your Fiscal Year-End
There is one Corporation Tax Return per income year, and no government fee for submitting it. The deadline depends on when your fiscal year ends.
| Fiscal year-end | Return due by |
|---|---|
| 1 January to 30 September | 15 March of the following year |
| 1 October to 31 December | 15 June of the following year |
For the 2024 income year only, a transitional extension applied. To ease the move to the updated return, corporate taxpayers were given until 31 July 2025 for both fiscal year-end groups, after an earlier interim extension had moved the dates to 17 April 2025 and 15 June 2025 respectively.
Prepayments are a separate timetable from the return itself. General companies, meaning those other than approved small businesses, prepay corporation tax monthly at one-twelfth of the tax payable on the taxable income of the year before the preceding income year, due no later than the 15th of each month.
Approved small businesses follow a lighter instalment pattern:
- Those with a 1 January to 30 September year-end pay one instalment by 15 September equal to 50% of the prior year's net tax, with the balance due on filing by 15 March.
- Those with a 1 October to 31 December year-end pay two instalments, by 15 December and by 15 March.
A company expecting lower profits than in the reference year may apply to reduce or waive its instalments. Note that monthly prepayments do not apply to a company with gross income under BBD 2 million that is registered as an approved small business under the Small Business Development Act.

How to File Online Through TAMIS with the Barbados Revenue Authority
Filing is online only. Returns are submitted through TAMIS at https://tamis.bra.gov.bb, and there is no paper alternative for current years.
Inside the platform, use the "Add Return" button to create a new return, then choose the Tax Type, Year, and Period. A return you have saved but not yet submitted can be reopened from the returns list by selecting "EDIT" beside it.
Attach the Capital Allowance and Wear & Tear Schedule when you file; the schedule is available to download from the help page. Returns can be filed for income year 2017 onward once registration is complete, while anything before income year 2010 must be prepared manually and uploaded with the 2010 submission.
A practical point for non-resident owners: an agent or adviser can be granted access to act on the entity's behalf within TAMIS, and queries can be raised through the in-system help function. This lets a local representative manage the filing and payment process without your physical presence.
Paying Corporation Tax Due
Tax is filed and paid in the same system. Within TAMIS, payment runs through the EZpay+ tab on the payments page, by credit card or by debit account.
The debit account route requires a one-time setup: register at ezpay.gov.bb, log in, open "Bank Accounts" to validate the account, and then select the debit option in TAMIS. For an in-person payment, file the return first, generate an Electronic Payment Advice, and either print it or write the EPA number on the back of a cheque presented to the cashier.
The balance of tax falls due on filing. A company with a 1 January to 30 September year-end pays any remainder by 15 March of the following year; one with a 1 October to 31 December year-end pays by 15 June. All amounts are in Barbados dollars, fixed at BBD 2.00 to USD 1.00.
Penalties for Late, Missing, or Incorrect Filing
Late or absent filings carry fixed and proportional charges, and these stack with interest the longer an amount stays unpaid.
| Default | Charge |
|---|---|
| Failure to file the return on time | BBD 500 plus 5% of tax assessed at the due date |
| Failure to pay income tax on time | 5% of the tax assessed and unpaid at the due date |
| Interest on unpaid tax and penalties | 1% per month on the largest amount outstanding in that month |
| Missing a CIT instalment | 10% of the instalment due, plus 0.5% per month interest on the outstanding instalment |
The Commissioner's officers hold broad audit powers. At any reasonable time they may inspect books, records, and other documents, examine property, request the owner's assistance, and seize or retain anything relevant to the information that should appear in the records.
Records and vouchers supporting a return must be kept for up to five years after the end of the relevant income year, unless the Commissioner directs otherwise. The authority can reduce or waive penalties in certain circumstances at its discretion, though no formal amnesty or escalation schedule is published.
Legal Basis: The Income Tax Act, Cap. 73 and the 2024 Amendments
The foundational statute is the Income Tax Act, Cap. 73, which imposes corporation tax on both resident and non-resident companies and operates on self-assessment. The Barbados Revenue Authority administers it under the Barbados Revenue Authority Act.
Two measures reshaped the regime in 2024. The Income Tax (Amendment and Validation) Act, 2024 and the Corporation Top-Up Tax Act, 2024 were assented to on 21 May 2024 with a commencement date of 24 May 2024, though most provisions take effect from 1 January 2024.
The amending Act sets the 9% standard rate and the 5.5% small-company rate, introduces the 4.5% rate on elected intellectual property income, fixes the five-year loss carry-forward limit from income year 2025, and lays out prepayment calculations. The top-up tax statute imposes the Qualified Domestic Minimum Top-Up Tax on qualifying resident members of large multinational groups to meet the 15% global minimum.
Two related duties sit outside the Corporation Tax Return and are covered separately: Country-by-Country Reporting, in effect for fiscal years beginning on or after 1 January 2021 with a return due 12 months after year-end, and economic substance obligations for accounting periods beginning on or after 1 January 2020. Treat both as distinct filings rather than part of the return discussed here.
Conclusion
For a foreign owner, the Corporation Tax Return is not optional and not contingent on turning a profit: the duty starts at incorporation and ends only on a clean dissolution. The mechanics are manageable from abroad, since registration, filing, and payment all run through one online system and an agent can be authorised to act for you.
The single thing to settle early is whether your company is resident or non-resident, because that decides whether you report worldwide income or only local-source income, and it drives which rates, credits, and prepayment rules apply.
