Per a current Legal 500 Private Client guide, an individual is Guyana tax resident if any of the following applies: presence in Guyana for more than 183 days in any calendar year (cumulative, not necessarily consecutive), permanent residence in Guyana except for temporary reasonable absences, or presence in Guyana with intent to reside there permanently. Residents are taxed on worldwide income; foreign-source income of non-residents is generally not taxed. Separately, capital gains tax applies to disposals of Guyana-situated assets regardless of the disposer's residency status - gains within 12 months of acquisition are treated as ordinary income, gains realized between 1 and 25 years after acquisition are subject to capital gains tax at 20%, and gains realized more than 25 years after acquisition are exempt.
Confirmed via a Director of Tax's published article in the Caribbean Tax Law Journal: Guyana has no Controlled Foreign Company regime under the Income Tax Act. The Corporation Tax Act instead relies on general anti-avoidance provisions, with the Guyana Revenue Authority monitoring arm's-length principles for intra-group transactions as its primary tool against profit-shifting, rather than a formal CFC attribution regime.
No formal ratio-based thin capitalization rule is imposed in Guyana generally. A targeted anti-avoidance rule does apply to a specific fact pattern: where a Guyana company pays or accrues interest on securities issued to a non-resident company that is either its parent or a fellow subsidiary under common non-resident ownership, restrictions apply to the interest deduction, administered under the Corporation Tax Act's general anti-avoidance and arm's-length framework described above (Guyana Revenue Authority oversight of intra-group transactions) rather than a separate numeric debt-to-equity ratio.
No domestic FBAR/Form 8938-equivalent requiring Guyana residents to self-report their own foreign accounts was identified. Guyana is party to a specific US information-exchange agreement - the Income Tax (Exchange of Information) (United States of America) Order 1992 - covering US federal income, self-employment, transfer, estate, gift, and excise taxes on one side, and Guyana income, corporation, property, and capital gains tax on the other. Separately and independently of Guyana law, US citizens and Green Card holders with Guyana accounts remain obligated to file FinCEN Form 114 (FBAR) once aggregate foreign accounts exceed USD 10,000, and potentially Form 8938, regardless of Guyana's own domestic requirements.
Guyana's treaty network is somewhat broader than many of its Caribbean neighbors, per PwC's current individual foreign-tax-relief page and corroborating sources: comprehensive double tax treaties exist with Canada (Double Taxation Relief (Taxes on Income) (Canada) Order 1987), the United Kingdom (signed August 31, 1992, in force December 18, 1992), the CARICOM member states (Double Taxation Relief (Taxes on Income) (Member States of the Caribbean Community) Order 1995), and the United Arab Emirates. Where a treaty applies, dividend withholding tax can be reduced from the 20% domestic rate to 15%, 10%, or 0% depending on the specific treaty and ownership threshold - for example, the UK treaty caps portfolio dividends at 15% and direct-investment dividends at 10%. No comprehensive US income tax treaty exists (only the 1992 information-exchange agreement noted above).
