If you run a business in Jamaica, you need to understand General Consumption Tax (GCT) - what it is, when to charge it, and how to calculate it correctly on your invoices. Getting it wrong can mean penalties from Tax Administration Jamaica (TAJ). This guide breaks it down simply.
What Is GCT?
General Consumption Tax (GCT) is Jamaica's consumption tax, similar to VAT in other countries. As of 2026, the standard GCT rate is 15%.
If your business earns over J$10 million in taxable supplies per year, you are required to register for GCT with Tax Administration Jamaica (TAJ).
Even if you're below the threshold, you can voluntarily register for GCT. This allows you to claim input tax credits on business expenses, which can reduce your overall tax burden.
How to Calculate GCT on an Invoice
The formula is straightforward:
GCT Amount = Subtotal x 15%
Invoice Total = Subtotal + GCT Amount
Example Calculation
You're a graphic designer invoicing a client for design work:
| Item | Amount |
|---|---|
| Logo Design | J$50,000 |
| Business Card Design | J$20,000 |
| Subtotal | J$70,000 |
| GCT (15%) | J$10,500 |
| Total Due | J$80,500 |
