Does number 12. AA on your W-2 represent how much your contributed to your Roth IRA?

[Carl]

Yes, it is the amount contributed to your employer sponsored ROTH 401(k) plan. That amount is taxable and is already included in box 1 of your W-2.

[dmertz]

Code AA indicates a contribution to a Roth 401(k).  A Roth 401(k) is not a Roth IRA.  Do not enter anything reported in box 12 of your W-2 anywhere in TurboTax other than on TurboTax's W-2 form.  Do not enter any of these amounts under Deductions and Credits as regular IRA contributions.

What is the maximum $ amount that I can contribute to my company's Roth 401 K?

[dmertz]

The maximum Roth 401(k) contribution for 2019 was $19,000 plus, for those over age 50 in 2019, a $6,000 catch-up; it's too late to contribute for 2019 unless you are self-employed and before the end of 2019 you made the election to make the Roth contribution.  For 2020 it's $19,500 plus a $6,500 catch-up.

Good thing I came here. Assuming people are going to know that a Roth IRA contribution is NOT the same as their Roth IRA contributions via their 401(k) is reckless and confusing.

[dmertz]

Roth contributions via the 401(k) are not Roth IRA contributions.  They are Roth 401(k) contributions.

Is there an income limit (MFJT) on who can contribute to Roth 401K?

[PattiF]

No, there are no income limits to contribute to a Roth 401(k).

Please see the comparison chart in this IRS piece.

There is no income limit affecting eligibility to make contributions to employer-provided retirement plans.

Enter amounts in box 12 of your W-2 only in box 12 of TurboTax's W-2 from, nowhere else in TurboTax.  A 401(k) is not an IRA.

Thanks @PattiF , it (Roth 401K) has been most confusing for me recently since it is first time using it with my new employer, and Google was not much helpful getting anywhere.

@dmertz Hello, I know this has been a while, but I'm hoping you can help. Turbotax thinks my box 12 amount is for a Roth IRA but it is a Roth 401k. So it is saying we over contributed, but we didn't, and now it won't let us file unless we enter our over-contribution amount in the deductions and credits area.  Any ideas on what we should do?

[RobertB4444]

What code is in box 12 with the amount?  If it is not AA then the system would not recognize your contribution as a Roth 401K contribution.

@juliaong

Thanks, @RobertB4444 Yes, it is AA. And I do not have the amounts anywhere in the deductions and credits part either, as that is a Roth IRA. I'm very confused. I decided to pay to have a turbotax person look into it. The first person I got on the phone couldn't help, so she said she would find someone and give me a call back.
