GST/HST Threshold Checker

This worksheet is designed to help sole proprietors keep an eye on the GST/HST small supplier threshold before it becomes a problem.

Many business owners do not run into GST/HST trouble because they misunderstand the rules. They run into trouble because they do not realize the threshold has started to apply to them. This tool provides a simple way to review revenue across consecutive quarters and notice when registration may soon need attention.

It is not a filing tool or a full GST/HST tracker. It is an early-awareness worksheet designed to help users reduce the risk of missed registration, late action, penalties, and interest.

Inside, the worksheet helps you:

• record taxable revenue by quarter
• review total revenue across four consecutive quarters
• see whether the $30,000 threshold may be getting close
• build a simple habit of checking before GST/HST becomes urgent
• reduce the risk of treating registration as an afterthought

This tool is best suited to sole proprietors, freelancers, and early-stage business owners who want a simple way to keep GST/HST threshold awareness visible without using a full bookkeeping system.
