In previous years i have opted to split my pension earnings with My spouse however I didn’t notice that option this year. Did I miss it or was it not an option this year?

Here's how to locate the pension splitting optimizer (which is found in the Review section)

1. open your return and click the Find option (magnifying glass) in the upper right corner,
2. type Pension and select Pension Split with your spouse from the list and select Go.
