Tax Treaty Relief in Belize

Belize operates one of the smaller treaty networks in the Caribbean. Rather than a web of bilateral agreements, its treaty framework rests on three pillars: the CARICOM multilateral convention (in force 1994), a bilateral arrangement with the United Kingdom (in force 1948, amended 1973), and a bilateral treaty with Austria. A network of 14 Tax Information Exchange Agreements (TIEAs) supplements these, and Belize joined the OECD Multilateral Instrument (MLI) in 2022. Understanding which pillar applies to a particular cross-border payment is the first step in determining whether Belize-source withholding tax (WHT) can be reduced.

What is the CARICOM double-taxation agreement and how does it affect Belize-source income?

The Agreement Among the Governments of the Member States of the Caribbean Community for the Avoidance of Double Taxation (commonly called the CARICOM DTA) was signed on 6 July 1994 and ratified by Belize on 30 November 1994 [1]. Eleven CARICOM states are parties: Antigua and Barbuda, Barbados, Belize, Dominica, Grenada, Guyana, Jamaica, Saint Kitts and Nevis, Saint Lucia, Saint Vincent and the Grenadines, and Trinidad and Tobago. The treaty's defining architectural choice is source-only taxation: investment income (dividends, interest, royalties, and management fees) is taxed exclusively in the state where it arises, not in the recipient's country of residence. For dividends, the treaty explicitly provides a ceiling rate of 0% at source within the intra-CARICOM relationship [2]. Royalties may be taxed at source at up to 15% of gross amount. Interest and management fees are taxable only in the source state, with no express ceiling below domestic rates in the treaty text itself, making the domestic WHT rate the operative cap unless specific bilateral relief under another agreement applies. In March 2025, CARICOM announced it had finalised a Protocol to modernise the treaty by adding provisions for exchange of information and dispute settlement, aligning it with current OECD standards [1].

What domestic tax rates apply in Belize before treaty relief is considered?

Belize levies two main taxes on business activity. Business Tax (BT) is charged on gross receipts at sector-specific rates -- not on net profit -- making it a turnover tax rather than a classical corporate income tax [3]. Rates range from 0.75% (radio, newspapers, domestic airlines) through 1.75% (general trade and commerce) to 6% (professional services), 15% (financial institutions, gaming), and as high as 19-24.5% for telecommunications. A flat 25% income tax applies to individuals on chargeable income above BZD 26,000 (approximately USD 12,900), with partial relief for earners between BZD 26,001 and BZD 29,000 [3]. Non-resident recipients of Belize-source income face WHT before treaty relief as follows:

Figures for Austria treaty dividend and interest rates are drawn from the PwC Worldwide Tax Summaries withholding-rate table for Austria [4]. The UK arrangement (1947, amended 1973) predates the modern OECD model and does not follow the same dividend/interest/royalty structure; its rate provisions must be read from the treaty text, available through the UK HMRC publications page [5].

How is treaty relief claimed, and what is a certificate of residence?

To claim a reduced WHT rate under any of Belize's treaties, the non-resident payee must ordinarily establish treaty eligibility to the Belizean payer at the time of payment [6]. The standard documentary instrument for this purpose is a certificate of tax residence (COR) -- an official document issued by the tax authority of the payee's home jurisdiction confirming that the payee is resident there for tax purposes in the relevant period. The Belize Tax Service (BTS), which administers income tax (BTS replaced the former Income and Business Tax Department branding), holds responsibility for granting treaty-reduced rates and for issuing CORs to Belize-resident entities claiming relief abroad. Applications are submitted through BTS at bts.gov.bz. Where a payer has already withheld at the domestic rate, the treaty-eligible payee may seek a refund of excess WHT, a process that requires submitting the COR, the payment documentation, and a written claim to BTS [6].

What TIEAs, CRS, and OECD obligations govern information exchange?

Belize has signed 14 Tax Information Exchange Agreements covering Australia, Belgium, Denmark, Faroe Islands, Finland, France, Greenland, Iceland, India, Ireland, Netherlands, Norway, Portugal, Sweden, and the United Kingdom (the UK TIEA supplements the 1947 arrangement) [7]. TIEAs enable the competent authorities of each signatory to request information on specific taxpayers; they do not reduce WHT rates, but their existence influences third-country risk assessments and banking access.

On automatic exchange, Belize signed the Multilateral Competent Authority Agreement on the Common Reporting Standard (CRS MCAA) on 29 October 2015 and began automatic exchanges in September 2018 [8]. Belize also operates under a FATCA Model 1 Intergovernmental Agreement with the United States, meaning Belizean financial institutions report US-account data to BTS, which forwards it to the IRS. Separately, Belize signed the OECD Multilateral Instrument (MLI) on 11 January 2019, deposited its instrument of ratification on 7 April 2022, and the MLI entered into force for Belize on 1 August 2022 [9]. The MLI modifies Belize's covered bilateral tax agreements to incorporate BEPS anti-avoidance provisions (principally the principal-purpose test), meaning the Austria and UK bilateral treaties are subject to MLI overlay.

What economic substance requirements apply to Belize IBCs, and how do they interact with treaty access?

The Economic Substance Act (ESA), effective 11 October 2019, requires Belize International Business Companies (IBCs) engaged in relevant activities to demonstrate genuine economic presence in Belize [10]. Relevant activities include banking, insurance, fund management, finance and leasing, headquarters operations, holding companies, intellectual property, distribution, service centres, and shipping. An IBC claiming Belize tax residency for treaty purposes must satisfy the ESA: adequate board meetings held in Belize, a quorum physically present, strategic decisions minuted, records kept locally, and core income-generating activities (CIGAs) conducted in Belize proportionate to the business. Annual Economic Substance Declarations are filed through the Registered Agent to the International Financial Services Commission (IFSC). Failure to demonstrate substance does not automatically void treaty eligibility, but it may result in classification as a non-included entity with corresponding loss of BZ-resident status, which would preclude treaty claims as a Belizean resident. The ESA was introduced expressly in response to EU concerns about profit-shifting through shell structures.

What is Belize's history on the EU list of non-cooperative jurisdictions?

Belize was added to the EU list of non-cooperative tax jurisdictions (the EU blacklist) in October 2023 following a negative assessment by the OECD Global Forum on exchange of information on request (EOIR) [11]. After Belize implemented remedial measures, the EU Council removed it from the blacklist on 20 February 2024 and moved it to Annex II (the cooperative greylist), pending the outcome of a supplementary Global Forum review [11]. That review concluded in March 2026: the OECD Global Forum assigned Belize a rating of Largely Compliant under the second-round EOIR peer review, resolving the primary concern that triggered the 2023 blacklisting [12]. The Largely Compliant rating reflects remaining minor gaps in beneficial ownership transparency and verification, which Belize has committed to address. As of June 2026, Belize is not on the EU blacklist. Practitioners working with structures that route through or into the EU should confirm current Annex II status at the time of each relevant transaction, as the list is reviewed twice yearly.
