Child tax credit for those two years, but only for children under 17, not 18.

If you are referring to the $2,000 per child non-refundable credit for children %26lt; 18 then No.

There is a credit called %26quot;eligible dependent%26quot; for those people that are not married nor in common-law relationship and have children %26lt; 18 living with them.
