Reply to "Eighty percent of active self-employed didn’t submit income tax returns last year -Auditor General finds."

What are the penalties for not filing a self-employment tax return? Are there any way of knowing how much a self-employed person make in a fiscal or calendar year in Guyana? Do they assess you based on prior year income, or put leans against your assets or business after a certain time?

Please enlighten me, Django.
