The Belize Tax Service Department (BTSD) is rolling out a mandatory Electronic Invoicing (E‑Invoicing) system that will require most businesses to issue invoices electronically through a government‑approved platform. The accompanying Frequently Asked Questions (FAQ) provides a comprehensive overview of the new regime, outlining the legal basis, scope, and timeline for implementation. It explains which taxpayers must comply, the categories of transactions covered, and the technical prerequisites such as acquiring a digital certificate and integrating with the tax authority’s API. The document details the step‑by‑step registration process, data submission standards, and record‑keeping obligations that align with audit requirements. It also addresses practical concerns including invoicing for exempt sales, handling adjustments, and the transition period for existing paper‑based systems. The FAQ emphasizes that businesses must begin issuing electronic invoices within six months of the regulation’s effective date and should start preparing their systems immediately to avoid disruption. Additionally, it outlines the support mechanisms available, such as help‑desk assistance, training resources, and authorized service providers, and highlights the penalties for non‑compliance. Stakeholders are encouraged to regularly consult the portal for updates and to submit queries through the designated channel to ensure a smooth adoption of the E‑Invoicing framework.
