W-2 employer’s 401k failed ADP/ACP testing and I’m getting a taxable corrective distribution. Can I put this in solo 401k?

I had 1099 and W-2 income income in 2022. My W-2 employer’s 401k failed ADP/ACP testing and I’m getting a taxable corrective distribution of about $2,100. Does this now free up 2022 contribution space, and could I now make a 2022 contribution to my solo 401k?



  1. As Alan indicated in two separate posts in the last day. Distributions of excess contributions are never rollover eligible. Using separate funds for employee deferrals would be subject to other restrictions.
  2. If the employee deferral limit has already been reached. A return of excess contributions does not restore the employee deferral space.
  3. Even if you have unused employee deferral space including the excess contributions. You could only make an employee deferral to a one-participant 401k in the  unlikely event you had an enabling employee deferral election in place by 12/31.
  4. You would need an employee deferral election something to the effect; “100% of compensation up to the employee deferral limit less deferrals to other 401k, 403b and SIMPLE IRA plans and within the annual addition limit.”

Ok, since it sounds like I cannot make an additional employee deferral, I am wondering what the reporting would look like here. I already rolled over the funds from my old employer 401k to my Solo 401k, so I’ll need to withdraw the $2,100 plus any investment gains. I think what I need to correct is the Solo 401k needs to issue me a 1099-R for 2022 showing gross distribtion in Box 1, any investment gains in Box 2a, and Box 7 should show the distribution code 8 for excess contribution. Does this sound right?

When did you roll over the old 401k, and did the plan just send you a letter that 2100 of the rollout was an excess contribution?  If so, they should issue a 2023 1099R coded 8 next January at the latest and another 1099R coded G for the  remaining balance rolled over to the soloK. Then, as you indicated, you will have to distribute the excess amount in the solo K adjusted for gain or loss and the solo K will have to issue a 2023 1099R coded E to report the corrective distribution.  In other words, the taxable distribution of the excess should be reported from the old K plan, and that amount then becomes an after tax excess amount rolled into the solo k that must be distributed adjusted for gain or loss. The 1099R from the solo K should show the gain (if any) in Box 2a and the difference between the gain and the gross distribution in Box 5. That will prevent double taxes on the same excess amount being distributed from two different plans. 

Let me describe the timing of events: March 2022- I contribute $20,500 to employer 401k for 2022. I leave W-2 employer and roll Transamerica 401k balance to my Vanguard IRA December 2022- I set up a Solo 401k and make an employer contribution based on my self employment income for the year January 2023- I make a transfer of assets from Vanguard IRA to Solo 401k February 2023- I receive email from W-2 employer informing me their 401k plan failed ADP testing, and I’ll be receiving a corrective distribution as an HCE March 2023- I recieve two 1099-Rs from Transamerica. One has gross disbution of of $18,198 with code G, second has gross distribution of $2,401.55, taxable amount of $2,401.55, and code 8.

Appreciate your help with this, Alan! I administer the Solo 401k so I will handle that reporting. Thanks again so much for explaining.
