Trinidad and Tobago Tax Filing Guide 2026

Overview — Tax Filing in Trinidad and Tobago

The Board of Inland Revenue (BIR) operates the eTAC (Electronic Tax Administration and Compliance) system for electronic tax filing, payment, and compliance management. Taxpayers register on the eTAC portal, obtain a Business Tax Account (BTA) number, and file all returns electronically. The system covers income tax (personal and corporate), VAT, PAYE, withholding taxes, the Green Fund Levy, and property tax. The BIR has been modernising its systems to improve taxpayer services and compliance monitoring. Most tax types are now filed exclusively through the eTAC portal.

Taxpayer Identification (BTA Number)

A Business Tax Account (BTA) number is required for all tax filings in Trinidad and Tobago. The BTA is a unique identifier for individuals and businesses. To obtain a BTA:

• Register on the BIR eTAC portal (https://etac.bir.gov.tt)
• Provide valid identification (passport, national ID, or business registration certificate)
• Receive your BTA number electronically

A BTA is required to file tax returns, make tax payments, correspond with the BIR, and obtain tax compliance certificates. Companies must have a BTA before they can operate legally in TT.

Filing Deadlines

Different taxpayers have different filing deadlines in Trinidad and Tobago:

• Individuals (self-employed and PAYE) — annual return by 30 April of the following year
• Companies — annual return by 30 April following the end of the accounting period
• PAYE (employers) — monthly return by the 15th of the following month
• VAT — quarterly return within 25 days after the end of each quarter
• Withholding tax — monthly return by the 14th of the following month
• Green Fund Levy — quarterly with VAT return or annually with CIT return

Late filing attracts a penalty of 10% of the tax due plus interest at the prescribed rate (approximately 1% per month). More severe penalties may apply for persistent non-compliance.

Self-Assessment & Quarterly Instalments

Self-employed individuals and companies must estimate their annual tax liability and pay in quarterly instalments:

• First instalment — due 31 March (25% of estimated tax)
• Second instalment — due 30 June (25% of estimated tax)
• Third instalment — due 30 September (25% of estimated tax)
• Fourth instalment — due 31 December (25% of estimated tax)

If the actual tax computed in the annual return exceeds the total instalments paid, the balance is due at the time of filing. If instalments exceed the actual tax, a refund may be claimed. Underpayment of instalments attracts interest at the prescribed rate.
