Box 040 of your Form T5013, Statement of Partnership Income will show the amount of CCA the partnership claimed on your behalf. This amount has already been deducted from the Business income in box 116 or the Professional income in box 120 of the T5013 slip. So it is for information only and doesn’t require you to input the amount.
