My taxpayer has a net business income and taxable of 12,587$. The taxpayer is a single individual and not handicap. Profile give me a CWB on line 45300 of 3,160$ whereas the maximum is 1,295$.
Hmmm, line 17 on the schedule that you provided indicates that he does have a spouse and an eligible dependant, so I am afraid you will have to get some technical assistance from Profile.
Everything is ok. Amount are different for Quebec resident:
