VAT tax invoices and record retention in Trinidad: an audit-ready checklist

What the customer should see on a tax invoice

The Inland Revenue Division requires a tax invoice to identify itself with the words 'Tax Invoice', carry an identifying serial number and issue date, and state the supplier's name, address and VAT registration number. It also identifies recipient name and address among the requirements.

The description of goods or services, exclusive amount, tax value and full total should be understandable without consulting an unrelated quotation. Check the complete IRD guidance for the particular form of tax invoice and transaction. A missing VAT number or misdescribed supplier can disrupt another business's bookkeeping.

Keep the purchase evidence too

Input VAT is not established simply because a business paid a supplier. Keep genuine tax invoices issued by VAT-registered suppliers and classify the underlying expenses correctly. Review whether the purchase is related to taxable business supplies and meets the IRD's conditions for credit.

A credit-card statement or bank transfer may show payment but not every detail required to substantiate input VAT. Attach the original supplier invoice, credit note where relevant, goods receipt and description of why the expense relates to the registered activity.

Apply the retention rule

The IRD's published VAT guidance says books and records should be retained for six years or three years from the date of filing returns, whichever is later. A business needs a retention procedure that preserves older years even after changing accounting software or closing a bank account.

Records must also be available in English, in Trinidad and Tobago currency and in a form enabling the Board of Inland Revenue to test return accuracy. Digitally stored information should be readable and backed up with access controls, not kept on an employee's private phone alone.

Build a predictable filing structure

Create folders or accounting records by tax period and keep separate streams for issued sales tax invoices, supplier invoices, credit notes, purchase details, VAT adjustments, bank reconciliations and filed return confirmations. Mark which documents relate to standard-rated, zero-rated or exempt treatment where applicable.

The folder should make a tax figure traceable to its underlying transaction. If a sales figure is revised later, retain both the original and the legitimate credit or correction documentation. An unexplained replacement of a tax invoice can make the audit trail harder to follow.

Prepare for a query from IRD

The IRD says invoices are not normally attached to VAT returns but must be available when requested. A company that files totals without preserving individual documents may be unable to substantiate a credit or explain a difference.

An owner can practise a simple review: choose five transactions at random, find their invoice numbers, confirm names and amounts, match them to the VAT ledger and reconcile the payment evidence. If that exercise cannot be done easily, the record system deserves improvement before an actual review.

Example: a small distributor

A distributor purchases stock, sells to retailers and issues 200 tax invoices per two-month period. The business uses a consistent numbering sequence and saves supplier invoices separately from sales invoices, then compares purchase and sales summaries with its VAT return.

A customer later asks for a replacement copy of an earlier invoice. The distributor can retrieve the original record without inventing a fresh invoice date or altering a historical transaction. This protects customer relations and the business's own audit evidence.
