If you have kids, your spouse's income may impact the amount you receive for the Canada Child Benefit (CCB). The CCB is calculated using your Adjusted Net Family Income (ANFI). See more details from the Government of Canada website here. Your ANFI is impacted by your RRSP contribution and by your spouse's RRSP contribution. The amount entered in the form on this website should be your spouse's portion of your ANFI.
