You are required to register for GST if your annual taxable turnover is more than $1million at the end of any calendar quarter (for periods prior to 2019) or end of any calendar year (from 2019 onwards).
This calculator helps you to compute your annual taxable turnover and determine whether you are required to register for GST for the calendar year 2019 onwards. To determine whether you are required to register for GST for earlier periods, please use the GST registration calculator (prior to 2019).
