Plan ahead
Sole proprietors often need to set aside income tax, CPP or QPP, Quebec QPIP where applicable, and sales-tax remittances separately from money available to spend. This estimate uses official brackets but does not replace a full return with personal credits and deductions.
GST/HST and QST in Quebec
If you are registered, GST/HST collected on invoices affects your net remittance everywhere in Canada. QST applies on Quebec supplies when you are registered with Revenu Québec. Pair this estimator with a line-by-line tax calculator.
