Whether you're a sole trader offering graphic design services or a registered company selling equipment, getting your invoices right isn't optional in Jamaica. Tax Administration Jamaica (TAJ) has specific requirements for what appears on commercial invoices — and getting it wrong can create problems during audits.
Here's a practical guide to what every Jamaican invoice needs, when GCT applies, and how to handle it properly.
Your TRN: The Foundation
Every Jamaican taxpayer has a Taxpayer Registration Number (TRN). It's a 9-digit number issued by TAJ, and it should appear on every invoice you issue. Even if you're not registered for GCT, your TRN identifies you as a legitimate business in Jamaica's tax system.
Place your TRN prominently on your invoice — typically near your business name and address at the top.
When Does GCT Apply?
General Consumption Tax (GCT) is Jamaica's goods and services tax, currently set at 15%. You're required to register for GCT if your annual gross revenue exceeds J$10 million. If you're below that threshold, GCT registration is optional.
If you're GCT-registered: You must charge 15% GCT on all taxable supplies and clearly show it on your invoice. Your GCT registration number must also appear on the invoice.
If you're not GCT-registered: Do not charge GCT. Your invoice should show the total amount without any GCT line item. Including GCT when you're not registered is actually illegal.
What Must Appear on a GCT Invoice
TAJ requires the following on every GCT invoice (also called a "tax invoice"):
Your business name and address — the name registered with TAJ
Your TRN — prominently displayed
Your GCT registration number — if registered
Invoice number — unique and sequential
Invoice date — when the invoice was issued
Client's name and TRN — for B2B transactions
Description of goods or services — specific, not vague
Quantity and unit price — for each line item
Subtotal — before GCT
GCT amount — clearly shown as a separate line
Total — subtotal + GCT
GCT Calculation Example
Let's say you're a web developer billing a client for a website redesign:
Website redesign (5 pages): $150,000 JMD
Hosting setup: $25,000 JMD
Subtotal: $175,000 JMD
GCT (15%): $26,250 JMD
Total: $201,250 JMD
The GCT must be shown as a separate line — you can't just inflate your prices by 15% and claim "GCT included" without showing the breakdown.
Invoicing International Clients
When you provide services to clients outside Jamaica, the GCT treatment changes. Exported services are generally "zero-rated" for GCT purposes — meaning you don't charge GCT, but you can still claim input tax credits on your GCT return.
Your invoice to an international client should note "Zero-rated — exported service" where the GCT line would normally appear. Keep records of the client's overseas address and the nature of the service to support the zero-rating.
Record-Keeping Requirements
TAJ requires you to keep copies of all invoices (issued and received) for at least six years. Digital records are acceptable as long as they're complete and accessible. If you're using invoicing software, make sure it stores invoice history and allows you to export records.
Penalties for Non-Compliance
Issuing invoices without a TRN, charging GCT when you're not registered, or failing to charge GCT when you should — these can all result in penalties from TAJ. The specifics vary, but the principle is simple: keep accurate records, charge the right tax, and file on time.
The easiest way to stay compliant? Use an invoicing platform that handles GCT calculation automatically, includes your TRN on every invoice, and stores your records digitally. It's less error-prone than manual invoicing and gives you a clean audit trail.
