How do I calculate my GST Threshold?

Your GST turnover is essentially your gross business income excluding GST included in sales, any sales that are not for payment, input-taxed sale, and sales not connected to Australia. To calculate whether you are over the threshold you simply take away any of the exclusions from your gross business income.

To determine if you meet the threshold look at your current GST turnover and your projected GST turnover. If turnover for the current month plus either the previous 11 months, or future 11 months equals $75,000 you must register for GST.
