Common questions

How much of my self-employed income should I set aside for tax in Canada?

A common planning range is 25% to 35% of profit once you add CPP, federal and provincial tax. Use your revenue and expenses here for a number built from the actual tables.

How much CPP do self-employed people pay?

You pay both halves: 11.9% of net self-employment earnings between $3,500 and the year's maximum pensionable earnings, plus 8% on earnings between that and the second ceiling (CPP2).

Do I have to pay tax quarterly?

If you owe more than $3,000 in the current year and also did in either of the two years before, CRA expects instalments on March 15, June 15, September 15 and December 15.

When must I register for GST/HST?

When your taxable sales pass $30,000 over four consecutive calendar quarters. GST/HST you collect is not your income, so keep it out of your set-aside.
