A lot depends on how much you make. You wont have to pay EI because you are self employed. tax and Cpp are based on your earnings. I usually pay between $800 and a $1200 dollars but that is mostly CPP. I know that I should put money away each week but life always seems to get in the way. Fortunately hubby gets enough of a refund that nothing comes out of our pockets, we just use his refund.
