Understanding the Annual Business Tax Return (Form BTS290) in Belize
Every company registered in Belize must file an Annual Business Tax Return, known officially as Form BTS290, with the Belize Tax Service Department (BTSD). This obligation is real and unconditional: it applies to all Belize companies, including the entities formerly classified as International Business Companies (IBCs) and now treated as Business Companies. The governing law is the Income and Business Tax Act, Chapter 55 of the Laws of Belize.
This article explains how the return works for a company owned from abroad: who must file, what the form captures, when it is due, how to submit and pay through the official online system, and what happens if a deadline slips. It is written for foreign business owners, investors, and the advisers who manage their Belize entities from outside the country.
A point that surprises many owners of former IBCs deserves stating early. The annual return must be filed even when a company earned nothing and even when its income is fully exempt from tax; the filing duty and the tax liability are two separate things.
Legal Basis: The Income and Business Tax Act and the Tax Administration and Procedure Act
Two statutes control this obligation. The Income and Business Tax Act (Chapter 55, Revised Edition 2020) sets the substantive rules: it imposes a business tax on the gross receipts of registered companies and fixes the filing deadline. The 2019 reforms, carried through several amending Acts, ended the automatic tax exemption that IBCs once enjoyed.
The filing rule itself sits in section 31(1) of that Act, which requires every chargeable person to file a return of income on or before the last day of the third month following the end of the basis year, without waiting for any notice or demand. In plain terms, the duty to file is on the company; the tax authority does not have to ask first.
The administrative machinery comes from the Tax Administration and Procedure Act (Chapter 51, Revised Edition 2020). That statute creates the office of the Director General of the BTSD, governs taxpayer identification numbers and record-keeping, sets enforcement powers, and grants the authority to extend deadlines. Most foreign owners never need to read either Act in full; what matters is that the return is mandatory and the penalties for ignoring it are statutory.

Which Companies Must File the Annual Business Tax Return
The filing obligation reaches every Belize company. Former IBCs, now registered as Business Companies, are firmly inside the net, and the BTSD has issued repeated reminders directed specifically at these entities.
Belize operates a gross-receipts business tax. Unlike a corporate income tax computed on profit, the levy applies to total revenue, with no deductions unless the authorities specifically grant them. Both resident and non-resident entities that conduct business in the country fall within the regime.
Exemption from the tax is possible, but narrowly. A company may avoid business tax where it is a non-included entity under the Economic Substance Act, is tax resident in a foreign jurisdiction that is not on the EU blacklist, and can produce supporting evidence such as a letter from that jurisdiction's tax authority or payment receipts.
Even a company that qualifies for a business tax exemption must still file Form BTS290. The exemption relieves the tax owed, not the obligation to lodge the return.
Every Belize company must also keep a registered agent resident in the country. That agent receives legal mail and supports compliance, but it does not displace the company's own responsibility to file.
Tax Registration Before Filing
A return cannot be filed without a Taxpayer Identification Number (TIN). Any business operating in Belize, whether a company, partnership, or sole proprietorship, must register with the BTSD to obtain one. Directors and shareholders are required to hold a TIN as well.
The number runs to seven digits, made up of a six-digit identifier and a single check digit, and is generated through the BTSD's revenue system once an application is accepted. Approval typically takes around seven working days.
For entities that were previously IBCs, registration follows a specific route. Under the Belize Companies Act (Act No. 11 of 2022) and the consolidation of the registries into the Belize Companies and Corporate Affairs Registry, former IBCs submit their TIN applications directly to the Belize Tax Service by email at Internationalcompliance@bts.gov.bz.
Two forms appear in the registration process:
- Form BTS101 registers shareholders, directors, and employees; a copy of a passport and, where relevant, a social security card supports the application.
- Form BTS104 records later changes, such as a new company name, address, or location, or cancels a registration.
No published government fee for issuing a TIN to a former IBC has been confirmed. Verify the position directly with the BTSD before assuming any charge applies.

What Must Be Reported on Form BTS290
Form BTS290 is the prescribed annual return, organised into five parts. The structure walks a filer from identification through to the final tax figure.
- Taxpayer information: company name, TIN, registration number, and contact details as held by the BTSD.
- Tax declaration and computation: gross receipts by activity type, the applicable rate, and the total business tax payable for the basis year.
- Statutory declaration: a signed, dated certification of the return's accuracy, including the signer's name and position.
- Foreign-source income: declaration of income arising outside the country.
- Net gain: supporting figures and documentation, including evidence where a foreign tax residency exemption is claimed.
Tax is charged at rates that depend on the kind of activity. Trade and general business income attracts 1.75 percent; rental income and licensable financial services to non-residents attract 3 percent; professional services attract 6 percent. A pure equity holding company that conducts no relevant activity is taxed at 0 percent, while certain regulated sectors such as telecommunications can reach rates as high as 19 percent.
| Activity | Rate |
|---|---|
| Trade and general business income | 1.75% |
| Rental income; licensable financial services to non-residents | 3% |
| Professional services | 6% |
| Pure equity holding company (no relevant activity) | 0% |
| Certain regulated sectors (e.g. telecommunications) | up to 19% |
Financial statements travel with the return. Former IBCs must include a certified copy of their annual financials. Where a company's gross receipts exceed US $6,000,000, or where it meets other criteria such as a stock exchange listing or IFSC regulation, audited statements prepared under IFRS are required; below that threshold, certified financial statements suffice. All returns and supporting documents must be submitted in English.
Filing Deadline, Basis Period, and Frequency
The return covers a basis year running from 1 January to 31 December and is filed once a year. The standard deadline is 31 March following the close of that year, the fixed date that section 31(1) produces by requiring filing in the third month after the basis year ends.
Returns for the 2024 basis year were due on 31 March 2025. The Director General has, however, granted relief for the following year: for former IBCs now registered as local companies, the due date for Business Tax Annual Returns and Financial Statement Returns for 2025 was extended to 30 June 2026.
No government filing fee for the return itself has been identified. Confirm this with the BTSD if budgeting precisely.

Nil Returns: Filing Obligations for Companies With Zero Revenue
A dormant company is not a silent one. Where a firm earned no revenue during the basis year, it must still file Form BTS290 declaring nil income.
The point is worth being blunt about: a company with zero tax to pay can still be penalised for failing to file. The filing obligation stands on its own, independent of whether any tax is owed.
The same logic applies to companies claiming a foreign tax residency exemption. They lodge the return with the supporting documentation from the overseas jurisdiction; the exemption removes the liability, not the paperwork. There is no carve-out for dormant or zero-revenue entities.
How to File Electronically Through the IRIS Belize E-Portal
Filing on paper is no longer an option. Effective 1 April 2023, returns and payments are accepted only online, through the Integrated Revenue Information System known as IRIS Belize, reached at irisbelize.bts.gov.bz. The official notice on online filing confirms the change. The BTSD no longer accepts payments at its offices.
The registration flow on the portal has one trap that catches first-time users. After authentication, the system emails an activation link that stays valid for only one hour; if it is not clicked in time, the sign-in process has to be repeated from the start.
During setup, a taxpayer tells the department which tax accounts to attach to the online profile and what permissions any sub-users should hold. Once the account is live and the return is approved on submission, the system records the filing electronically, and the BTSD issues a confirmation once it accepts the return. Payments register in the account in real time.
All queries and correspondence now route through the Taxpayer Services Unit at tps@bts.gov.bz, the single contact point for registration, filing, account questions, and general assistance.
Paying Tax Due on the Annual Business Tax Return
Payment follows the same online-only rule as filing. Tax is settled through IRIS Belize, and amounts paid appear in the account immediately. Office-counter payment is not available.
Remember that the tax is calculated on gross receipts, not net profit, so the figure owed reflects revenue at the activity rate with no deductions unless the authorities have specifically allowed them. A monthly Statement of Account shows the running position of debits and credits, which lets a foreign owner reconcile from a distance.
Where a payment is allocated to the wrong tax type, it has to be corrected with the BTSD directly. Accepted payment methods inside IRIS are not published in detail; confirm the options with the Taxpayer Services Unit or the portal help desk before a deadline rather than after.
Requesting an Extension From the Director General
Section 31 of the Income and Business Tax Act gives the Director General power to extend the standard 31 March deadline, and that power is used in practice. The extension for the 2025 returns to 30 June 2026 is a live example, issued by official notice to former IBCs as a group.
Extensions in Belize tend to be granted collectively, by Director General notice and press release, rather than through a per-company application form. No standard individual extension form has been published; a company needing relief should approach the BTSD directly at tps@bts.gov.bz or through IRIS.
A later filing date does not push back the date tax is due. Late-payment interest continues to accrue on any outstanding balance regardless of a filing extension, so settle the liability on time even if the return follows.
Companies should also note that updated late-filing penalties took effect on 1 January 2025; outstanding returns need to reach the BTSD by whatever extended date the Director General has announced to stay clear of them.
Penalties for Late or Incorrect Filing
Missing the deadline carries a defined cost. Late filing is penalised at 10 percent of the tax due for each month of delay, subject to a minimum of BZD 10 per month and a ceiling of 24 months. Late payment is charged separately at 1.5 percent per month on the unpaid balance.
Persistent failure escalates. In serious cases, a company that does not file can face a fine of up to BZD 10,000, imprisonment of up to two years, or both, and the BTSD may pursue arrears and penalties for up to six years from the date of the breach.
| Breach | Rate / amount | Cap |
|---|---|---|
| Late filing | 10% of tax due per month (min BZD 10/month) | 24 months |
| Late payment | 1.5% per month on unpaid balance | None stated |
| Failure to file (criminal) | Fine up to BZD 10,000 and/or imprisonment | 2 years' imprisonment |
| Recovery limitation period | Up to 6 years from violation | — |
Enforcement under the Tax Administration and Procedure Act moves in stages. Where public disclosure of defaulters does not produce compliance, the department turns to liens on property, levies on assets, and the courts. Recent amendments let a court compel a person to file by a set time, and paying a court-imposed fine does not discharge the underlying duty: the return must still be filed.
Conclusion
The lesson for any foreign owner of a Belize company is that filing Form BTS290 is not optional and not waived by inactivity or exemption. A dormant entity, a zero-revenue entity, and a fully exempt entity all owe the same annual return, and the penalties for skipping it now bite harder than the old IBC regime ever suggested.
Before the next 31 March, or whatever extended date the Director General has set, confirm that the company holds a valid TIN, that its financial statements are ready in English, and that its IRIS Belize account is active. Treat the filing date and the payment date as separate obligations, because an extension to one does not move the other.
