Is the IRA Contribution the same as box 12c code AA on your w2

[JulieS]

No,an IRA contribution is usually made by an individual account holder outside of their work.

Code AA in box 12 of your W-2 form is a designated Roth contribution to a 401(k) plan. Because it is on the W-2 form, the contribution was handled by your employer and the figure should not be entered as an IRA contribution on your tax return.

And to be clear, a 401(k) plan is not an IRA.
