Ha! Yes, you do need to pay it. And you can pay it at any of the Paymaster locations as well as any of the tax offices island wide. The tax offices can be paid online at this link:

You should be able to pay online using Paymaster Online:

If you plan on visiting Jamaica again, please pay the ticket. It will save you much grief in the future. And you are lucky you didnt get taken in for trying to bribe an officer. That old, misguided information to say "how much is the fine if I pay it now?" will generally get you a "go directly to jail, do not pass go" kinda day... (grin)
