Can I Transfer RRSP income that I received (in my name), onto my spouse's tax return? Is this considered "income splitting"?

No, you must report any amount reported on a T4RSP issued in your name and SIN on your own return. (There are cases where withdrawals from "spousal RRSPs" are reported as income for the spouse who contributed, not the annuitant whose name and SIN is on the slip).

This is not considered to be Income Splitting. Income Splitting does not apply to most taxpayers, and Pension Income Splitting does not apply to RRSP withdrawals.
