This credit has been changed for 2015 and now it is a “refundable tax credit”. That means that even if you have no taxable income at all, you can still get a refund of up to $150 per child.
We did have quite a few of these credits reviewed by CRA this year and many of the receipts were denied because they didn’t have one specific piece of information or another. If you have questions about a specific program or if your receipt is valid, let us help you.
