You would enter the T3 slip for one spouse, then at the bottom of the T3, enter a percentage in the box labeled “Enter percentage of slip to claim on your spouse's tax return (if applicable).” Then click the “Done with T3” button to go to the “T3 – Summary.” When you are finished entering all your T5 slips, click on “Done with T3s,” and continue on until the “Here's your income summary.” You will see the T3 split on that page, not the “T3 – Summary” page.
If you have imported the information from CRA by using Auto-Fill, we suggest deleting the slip and re-entering it again.
Thank you for choosing TurboTax.
