Canadian Registered Pension Plan

[KS99]

Is a "registered" Canadian Pension plan considered a "qualified" retirement plan (as defined in IRC code sections 402 through 408 or section 457)? I can't tell if this is addressed in the Canada-US tax treaty. In my case, the State of Illinois want proof before they will allow me to subtract the retirement income.

A "pension" is not a qualified plan, and distributions are taxable income to the recipient.

Read https://smartasset.com/retirement/what-is-a-pension-plan to understand just what a pension plan is and to confirm that is "in fact" what you have.

I believe most pensions ARE qualified plans:

Also, I see there is a check box near the bottom of the TurboTax generated 1099-R form which states "Check if NOT from a qualified retirement plan or IRA"

My dilemma is how to determine if a Canadian pension can be considered qualified (just as is my US employer pension is). In Illinois, qualified retirement income can be subtracted from federal AGI.
