Expat Tax Residency in Trinidad and Tobago

Trinidad and Tobago levies income tax under the Income Tax Act Chap 75:01, administered by the Inland Revenue Division (IRD). For foreign nationals, understanding the residency tiers is the essential first step: where you sit on that spectrum determines whether you owe tax on income earned anywhere in the world or only on income sourced inside TT.

How does the 183-day rule make you a tax resident?

A person is treated as a tax resident of Trinidad and Tobago if they have actually resided in the country at one or more times for a period equal in the whole to six months -- 183 days -- of the income year (January 1 to December 31). Days do not need to be consecutive; part-days generally count as full days. Once that threshold is crossed, residency applies for the entire income year and worldwide income is in scope. The Ministry of Finance states plainly that a non-resident is "a person who is employed or a company that is operating in TT for a period of less than 183 days in any year" -- the mirror-image confirmation of the 183-day trigger [1].

What does 'ordinarily resident' and 'domiciled' add to the picture?

The Income Tax Act uses three overlapping concepts: resident, ordinarily resident, and domiciled. PwC's Worldwide Tax Summaries (last updated 2 June 2026) confirm that persons who are resident, ordinarily resident, or domiciled in Trinidad and Tobago are taxed on their worldwide income whether or not those earnings are remitted to TT [2]. Ordinary residence reflects habitual or settled residence over time -- a person who lives in TT year-after-year is ordinarily resident even if they spend a particular year partly abroad. Domicile is the jurisdiction a person treats as their permanent home; it is harder to shed than ordinary residence. Either status alone is sufficient to trigger full worldwide taxation, independent of the 183-day count.

What is the special rule for residents who are not domiciled in TT?

An important carve-out applies to individuals who are resident in TT but not domiciled there. Under the Income Tax Act, income arising outside Trinidad and Tobago and received by an individual who is resident but not domiciled in TT is taxable only to the extent that such income is received in (remitted to) Trinidad and Tobago [3]. This mirrors the UK's historic remittance basis. Foreign investment income left offshore, for example, falls outside the TT tax net for a non-domiciled resident -- but any amount wired into a TT bank account becomes taxable. Employment income is a critical exception: if the employment is exercised in TT, the gains are treated as TT-source income regardless of where payment is received, so non-domiciled residents cannot shelter TT-worked salary by routing it abroad.

What tax rates and allowances apply to residents?

Chargeable income is calculated after subtracting the personal allowance and qualifying deductions from gross income. The personal allowance for resident individuals is TTD 90,000 per year [4]. Chargeable income above that allowance is taxed at the rates in the table below. The 30% band applies to the slice of chargeable income above TTD 1 million -- not the full amount. Non-residents are generally not entitled to the personal allowance (the exception is non-resident pensioners drawing a pension sourced from TT). Non-resident individuals are taxed on income arising in TT, subject to applicable double-taxation treaties.

Do foreign nationals need a work permit before they can work in TT?

Yes. No non-citizen may legally work in Trinidad and Tobago without a work permit issued by the Ministry of National Security, except for a single period not exceeding 30 days in a 12-month period. A permit is tied to a specific employer and must be renewed annually. Applications must be submitted online through the Ministry at least three months before the intended start date; processing typically takes three to six months. The employer must demonstrate that no qualified citizen or resident is available to fill the role. Separately, non-resident workers must register with the IRD's International Tax Unit on arrival, bringing their contract, passport, and work permit for an assessment of their TT tax liability [5]. Crossing the 183-day mark mid-year -- which can happen to a permit-holder on a multi-year assignment -- automatically shifts the individual into resident status for that full income year.

How does residency start, change status, and end?

Residency begins from the first day of presence in TT and crystallises once the 183-day total is reached in a given income year. Residency does not continue automatically into the next year: each year is assessed on its own day-count and status indicators. A person who was ordinarily resident for several years but then permanently departs and severs ties may lose that status; domicile, however, requires a formal change of domicile of choice with clear evidence of intent to remain in a new jurisdiction indefinitely. The IRD can issue a certificate of residence confirming a taxpayer's status; this document is sometimes required by foreign tax authorities under double-taxation treaties to establish TT residency for treaty relief purposes. Taxpayers seeking one should contact the IRD's International Tax Unit at Trinidad House, St Vincent Street, Port of Spain. The IRD's related Tax Clearance Certificate (Form P14) is required for work permit extensions, citizenship applications, and certain government contracts, and confirms that returns are filed and taxes current [5].

For cross-border situations involving income from multiple countries or departure mid-year, the interaction of TT residency rules with double-taxation treaties and the remittance basis can become intricate. Consulting a qualified tax professional with TT experience is the appropriate step before making decisions.
