How to Calculate GCT on Invoices in Jamaica (2026 Guide)

Everything you need to know about General Consumption Tax (GCT) for your Jamaican business. Calculate correctly, avoid penalties, and stay compliant with TAJ.

10 min read | February 2026

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%.

Who Must Register for GCT?
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

What Must Appear on a GCT Invoice

TAJ requires the following information on every tax invoice:

  1. The words "Tax Invoice"
  2. Your business name and TRN (Taxpayer Registration Number)
  3. Your GCT registration number
  4. Invoice date and sequential invoice number
  5. Customer's name (and TRN if they're GCT-registered)
  6. Description of goods or services
  7. Subtotal amount
  8. GCT amount (shown separately)
  9. Total amount
Important: GCT must be shown as a separate line item on your invoice. TAJ can reject invoices that bundle GCT into the total without showing it separately.

GCT-Exempt Items

Not everything is subject to GCT. Common exemptions include:

  • Basic food items (rice, flour, sugar, cornmeal)
  • Medical services and prescription drugs
  • Educational services
  • Residential rent
  • Financial services
  • Public transportation
  • Water (piped)
  • Exports

For a complete list of GCT-exempt items, refer to the TAJ website.

Common GCT Mistakes to Avoid

Mistake #1: Not separating GCT on the invoice
TAJ requires GCT to be shown as a separate line item. Don't just show a total that "includes GCT."
Mistake #2: Charging GCT when you're not registered
You cannot legally charge GCT unless you're registered with TAJ. If you're not registered, your invoice should not include GCT.
Mistake #3: Forgetting to file GCT returns
GCT returns are due by the 25th of the month following the reporting period. Late filing attracts penalties and interest.
Mistake #4: Not keeping proper records
TAJ can audit up to 6 years of records. Keep copies of all invoices, receipts, and tax filings.
