Quick Method for Ontario sole proprietors
Ontario's 13% HST means you collect a meaningful amount on every invoice. Under the Quick Method, Ontario service providers remit just 8.8% of their tax-included revenue to CRA — keeping the 4.2-point spread as additional income. With the largest concentration of registered sole proprietors in Canada, Ontario consultants, designers, and freelancers are among the biggest beneficiaries of this election.
To elect the Quick Method: file Form GST74 with CRA before the first day of the reporting period you want it to apply to. Once elected, you must stay on Quick Method for at least one full fiscal year before switching back.
Who can't use Quick Method: accountants, bookkeepers, lawyers, notaries, financial advisors, and actuaries are ineligible in all provinces. Most other sole proprietors with annual taxable revenue under $400,000 qualify.
