Belize GST calculator 2026

General Sales Tax (GST) in Belize is charged at a standard rate of 12.5%. The Belize Tax Service states this rate in its current documents for businesses that issue tax invoices.

Use the calculator in two ways. Enter a price before tax to see the GST and the total, or enter a shelf price that already includes GST to see how much of it is tax.

How it's calculated

To add GST, multiply the price before tax by 12.5% and add the result to the price.
To take GST out of a price that includes it, divide the total by 100 plus the rate and multiply by the rate. At 12.5% that is the total times 12.5 divided by 112.5.
The Belize Tax Service works its own invoice examples the same way, with the tax applied to the value of the sale after any excise duty and environmental tax have been added.
Zero-rated and exempt supplies do not carry GST at the standard rate. Check the GST schedules, or ask the Belize Tax Service, before you apply the rate to a particular good or service.

An example

A supplier sells diesel and the value of the sale before GST is BZ$26,964.30. GST at 12.5% is BZ$3,370.54, so the customer pays BZ$30,334.84. This is the example used in the Belize Tax Service manual for electronic tax documents.

For a shelf price that includes GST, take BZ$225.00. The tax inside it is BZ$25.00 and the price before tax is BZ$200.00.
