Excess Deferral to 401k due to a merger

[laura0805]

Discovered excess deferral of ~$4500 recently, contacted plan administrator Monday morning 4/8. Expected response in 48 hours. Nothing to date. What do I need to do avoid being taxes twice.  Thanks!

Please be aware, if you do not take out the excess amount by April 15th, then you are taxed twice on the excess deferral left in the plan.  This happens once when you contribute it and again when you receive it as a distribution. You can't include the excess amount in the cost of the contract even though you included it in your income.

Please check with you plan administrator if they can process this in time.

You must include the excess deferral in your wages in the year the excess deferral happened. 

Please follow the steps below to enter the excess deferral on your 2023 return:

1. Login to your TurboTax Account 
2. Click "Wages & Income" (under Federal) on the left side of your screen
3. Scroll  down to "Less Common Income" and click "Show More"
4. Scroll down to "Miscellaneous Income, 1099-A, 1099-C" and click "Start"
5. Select "Other income not already reported on a Form W-2 or Form 1099" and click "Start"
6. On the "Did you receive any other wages?" screen answer "Yes" and click "Continue"
7. Continue until you get to the "Any other earned income" screen, answer "Yes" and click "Continue"
8. On the "Enter Source of Other Earned income" screen select "Other" and click "Continue"
9. On the "Any Other Earned Income" screen enter "2023 Excess 401(k) Deferrals" for the description, enter the amount and click "Done".

If you receive the distribution of the excess deferral and earnings by April 15th then please note for the Tax Year 2024 tax filing due April 15, 2025: 

2024 Forms 1099-R will be issued reporting the excess.

• Form 1099-R with Code P in box 7 can be ignored if you reported the excess as described above in 2023. 
• However, the earnings on Form 1099-R with Code 8 in box 7 should be reported in 2024.
