As self employed, do I now have to enter my GST and PST collected even though I already file these taxes. I notice this changes balance considerably?

If you are a GST Registrant, there is no need to include the GST in your income or expenses on the Business Statement.

If you remit PST, it is included in income, then subtracted on the line/box that asks about GST/HST/PST
