Box 26

[sharronammann]

When I am filling in the boxes from my t4 to the easy form on turbo tax, on the left hand side I can see I am getting a refund, when I put the info into box 26 as indicated on my t4 it now shows I have to pay in. Please explain why as box 26 is not income.

Box 26 is for CPP/QPP pensionable earnings. If you didn't pay enough into CPP/QPP, you would have to do so on your tax return, which can cause you to owe money to the CRA.
