BIR Audit Support in Trinidad & Tobago

When the BIR comes calling

Few letters concentrate the mind like one from the Board of Inland Revenue (BIR). Whether it is a routine request for information, a detailed query on a specific return, or a formal assessment proposing additional tax, the instinct is to worry — and to wonder how serious it really is. The honest answer is that a BIR audit is manageable, but only if it is handled correctly from the start.

The difficulty for most businesses is that an audit lands in unfamiliar territory. The correspondence uses technical language, the deadlines are firm, and a poorly judged response — conceding a point too quickly, or supplying more than was asked — can turn a narrow query into a broad examination. Many businesses make their position worse simply by trying to be helpful without understanding what is at stake.

Handled well, an audit is a process with rules, rights and remedies. With experienced representation, the great majority of matters are resolved sensibly, and where an assessment is wrong, there are clear routes to challenge it. The key is to engage the right help early, before informal replies harden into positions that are difficult to walk back.

It helps to understand what BIR is actually doing. An audit is not an accusation; it is a request to substantiate what you have already declared. The officer wants to see that the figures on your returns are supported by records and applied correctly under the law. Where they are, the matter closes. Where they are not, the officer proposes an adjustment — and it is precisely at that point that experienced advice changes the outcome, because the difference between an adjustment that stands and one that is reduced or withdrawn usually comes down to how well the position is documented and argued.

How BIR audits work in Trinidad & Tobago

The Board of Inland Revenue, within the Inland Revenue Division of the Ministry of Finance, administers Trinidad & Tobago's main taxes — corporation tax (currently 30% for most companies, higher for petrochemical and certain regulated sectors), the Business Levy (currently 0.6% of gross revenue) and Green Fund Levy (currently 0.3%), VAT (currently 12.5%, filed bi-monthly), and payroll taxes including PAYE, Health Surcharge and NIS. An audit can touch any one of these, or several at once.

BIR does not select cases at random alone. Reviews are commonly prompted by mismatches between returns, unusual movements in declared income or expenses, persistent losses, large refund claims, late or inconsistent filings, and industry-wide focus areas. Once a matter is opened, it typically moves through stages: an initial request for records and explanations; a review of the responses; a proposed adjustment or assessment setting out additional tax, interest and any penalties; and then, if you disagree, a formal process to object and, if necessary, appeal.

Because deadlines to respond and to object are strict, the single most important step is to act quickly and deliberately at each stage.

How Andersen TT helps

We take the audit off your desk. From the moment a query or assessment arrives, a partner reviews what BIR is actually asking, assesses the real exposure, and sets the strategy — what to provide, how to frame it, and which points to contest. We then manage the correspondence and the technical arguments on your behalf, so you deal with us rather than with the pressure of the process.

Our approach is measured and constructive. The objective is a fair, defensible outcome reached efficiently — not a confrontation for its own sake. Where BIR has a valid point, we help you resolve it cleanly and limit the cost. Where an assessment is overstated or wrong, we build the case, lodge a formal objection, and pursue an appeal where that is the right course.

Tone and timing matter as much as the technical argument. A response that is precise, professional and on time signals a taxpayer in control of their affairs and tends to keep an examination focused. A response that is late, defensive or inconsistent invites the opposite. Because we manage the exchange day to day, we keep the engagement on track — meeting every deadline, answering exactly what is asked, and ensuring nothing said in one reply undermines a position taken in another. That consistency is often what turns a tense matter into a routine one.

Because Andersen TT runs no in-house statutory audit practice, our advocacy is wholly independent — we represent your interests with no competing relationship to manage. And as the only accredited Andersen Global member firm in Trinidad & Tobago, where a matter involves cross-border issues we can draw on international colleagues to support the position.

Our BIR audit support services

We provide end-to-end support across the audit lifecycle:

• Initial query response — reviewing what BIR has asked and crafting a precise, complete reply.
• Audit management and liaison — acting as your point of contact with BIR throughout the examination.
• Records and documentation — assembling and presenting the supporting evidence BIR requires.
• Assessment review — analysing proposed adjustments and quantifying the true exposure.
• Objections — preparing and lodging formal objections to assessments you dispute, within the required time limits.
• Appeals support — advancing matters to the appropriate appellate stage where resolution is not reached.
• Penalty and interest mitigation — arguing for relief where the facts support it.
• Voluntary disclosure — helping you come forward on identified issues on the best available terms.
• Representation — experienced partners speaking for you in dealings with BIR.

Signs you should call us now

The earlier we are involved, the more we can do. Get in touch if:

• You have received any letter, query or request for information from BIR.
• You have been issued an assessment proposing additional tax, interest or penalties.
• You disagree with an assessment and the window to object is running.
• You are partway through an audit and feel out of your depth, or worry earlier replies have weakened your position.
• You have identified an error in a past return and want to disclose it on the best terms.
• You suspect your records would not stand up to scrutiny — a tax health check can find and fix gaps before BIR does.
• Your matter involves related-party or cross-border pricing, where our transfer pricing team can support the defence.

Why choose Andersen TT

In an audit you want two things: someone who knows the rules cold, and someone who is unambiguously on your side. Andersen TT delivers both. Our engagements are partner-led — an experienced adviser owns your matter, with more than 50 years of combined partner experience behind the firm — not a file passed down to junior staff.

Our independence is a real strength here. With no statutory audit arm, we have no conflicting relationship and no reason to soften our advocacy; we argue your case wholly in your interest. As the only accredited Andersen Global member firm in Trinidad & Tobago, we bring Big-Four-calibre technical depth with the responsiveness and direct access that the Big Four seldom give SMEs, family businesses and international investors.

Above all, we bring calm. An audit is stressful precisely because it is unfamiliar; for us it is routine. We handle the deadlines, the technical exchanges and the negotiation, and keep you clearly informed at each step. For broader resilience, pair audit support with proactive corporate tax advisory and a periodic tax health check.

How we work an audit

Our process is designed to take pressure off you while protecting your position:

1. Rapid assessment. We review the BIR correspondence, identify what is genuinely at stake, and confirm the deadlines.
2. Strategy. We agree the approach — what to provide, what to contest, and the outcome we are targeting.
3. Response and liaison. We prepare the replies and documentation and manage all contact with BIR.
4. Objection or settlement. Where the assessment is wrong, we object formally; where a point is valid, we resolve it efficiently.
5. Appeal and closure. If needed we escalate to appeal, and we see the matter through to a documented resolution.
