t4 box 24 should be same as 14
T4 slip-NEW RULES went into effect January 2012 for boxes 24 and 26. I've been asked whether the same number in box 14 needs to be entered into box 24 (EI insurable earnings) and box 26 (CPP/QPP Pensionable earnings) or can they be left blank when preparing the T4 slip.CRA introduced new rules for completing a T4 slip as a result of the changes to CPP.Boxes 24 and 26 must ALWAYS be completed now. Prior to 2012, it was acceptable and normal to have boxes 24 and 26 on the T4 slip blank when they matched box 14.For each box, you need to enter the total amount up to the maximums for the year OR zero if exempt. IF there are no insurable and/or pensionable earnings, you need to enter 0 in the field.oxes 24 and 26 must ALWAYS be completed now.
