Sales tax
Ontario charges 13% HST on most sales. Once your sales pass $30,000 in four quarters in a row (or in one quarter), you register, charge it and file GST/HST returns.
Income tax
Ontario taxes income at 5.05% to 13.16% in 2026, on top of federal tax of 14% to 33%, on the profit from your business.
CPP
Working for yourself, you pay both halves of CPP: 11.9% of your earnings from $3,500 to $74,600 in 2026, plus 8% more up to $85,000.
