What kind of plan are you referring to? There are a number of non-qualified plans.
Are you referring to a Deferred-compensation plan? If so, what IRS section refers to it?
Any of those plans. The answer is W-2 form.
I don't understand, after all W-2 data are input, why TT is asking if it is a contribution or withdrawal, when boxes 1 and 11 are filled in. If it was a contribution, box 1 would be blank.
Employers use box 11 to report money you put into a non-qualified plan in a prior year, but they also may use it to report money that you withdrew from a non-qualified plan. Thus, TurboTax needs to ask whether the amount was a contribution or a withdrawal.
But if box 1 contains data, it is definitely not a contribution. The program should be able to detect it and make the related determination.
Please read W2 instructions issued by the IRS regarding Box 11. It mentions Under nonqualified plans or nongovernmental 457(b) plans, deferred amounts (contributions) that are no longer subject to a substantial risk of forfeiture are taxable even if not distributed. Report these amounts in boxes 3 (up to the social security wage base) and 5. Do not report in box 11 deferrals included in boxes 3 and/or 5 and deferrals for current year services (such as those with no risk of forfeiture).
In answer to your question, the contribution should be reflected in Boxes 3 and Box 5 and not in Box 11. Reach out to us if you need further assistance.
