402G Excess Contribution in 2023 - How to Handle Refund on Tax Return?
I switched employers last year (2023) and accidentally over-contributed to my Traditional 401Ks by about $276. I caught the mistake and contacted the plan administrator in February 2024 to request a refund of the excess. They processed it and I received the refund by March 15th, 2024, but my former employer never sent an updated W2. Fast forward to now - I just received two separate 1099-R forms in January 2025 for this situation. Both forms are related to the excess contribution refund, but I'm totally confused about how to handle these on my 2024 taxes. Do I need to report these? Will this affect my 2023 return that I already filed? Should I be amending something? Has anyone dealt with 402G excess contributions before? I really don't want to mess up my taxes over a $276 mistake!

The good news is that you caught and corrected your 402G excess contribution within the proper timeframe! Here's how to handle those 1099-Rs: Those 1099-R forms you received in January 2025 are for reporting the correction of your 2023 excess 401k contribution. One form likely shows the return of the $276 excess contribution itself, while the other probably reports the earnings on that excess amount (if any). You'll need to include both 1099-Rs on your 2024 tax return (the one you're filing now in 2025). You don't need an updated 2023 W-2 because the excess contribution is handled through the 1099-R reporting. You also don't need to amend your 2023 return because the correction is reported on your 2024 return instead. When you enter these 1099-Rs in your tax software, make sure to indicate they're for a returned excess contribution. Most tax software has a specific option for this scenario.

•Thanks for the quick response! That makes sense, but I'm still a bit confused about the tax implications. Will I owe additional taxes on these 1099-Rs? The excess amount was already taxed as income in 2023, so it seems like I'd be double-taxed if I report it again on my 2024 return. Also, how do I indicate in TurboTax that these are for returned excess contributions?

•You won't be double-taxed on the principal amount of $276 since that was already included in your taxable income for 2023. When you properly code the 1099-R in your tax software as a returned excess contribution, the system will recognize that the principal shouldn't be taxed again. However, any earnings on that excess amount will be taxable for 2024. That's probably why you received two 1099-Rs - one for the principal and one for the earnings. In TurboTax, when entering the 1099-R, you'll see a question asking about the reason for the distribution. Look for options like "correction of excess contribution" or "returned excess contribution." Select that option and follow the prompts. TurboTax should then properly handle the tax treatment.

After dealing with a similar 402G excess contribution issue last year, I found this online tool that was super helpful for understanding the tax forms: https://taxr.ai I uploaded my 1099-Rs and W-2s, and it immediately flagged my excess contribution situation and explained exactly how to handle it. It even generated a detailed explanation of which boxes on the 1099-R forms corresponded to the principal vs. the earnings, which was confusing me. The tool explained that one 1099-R had a code "P" in Box 7 (which means principal return) and shouldn't be taxed again, while the other had code "8" (for earnings) that IS taxable. Worth checking your forms for these codes!

•Did this actually work? I'm dealing with a similar situation where I over-contributed to both a Roth 401k and traditional 401k because of job changes. The plan administrator sent me like 4 different 1099-Rs and I'm totally lost. Can it handle multiple forms at once?

•I'm skeptical about these "upload your tax documents" services. How do you know your sensitive financial info is secure? What if they sell your data or get hacked? Seems risky just to get some tax advice.

•It worked perfectly for me! Yes, you can upload multiple forms at once - I had 3 different 1099-Rs (two for the excess principal from different plans and one for combined earnings). The system analyzed them all together and explained how they related to each other. Regarding security concerns, I had the same worries initially. What convinced me was that they use bank-level encryption and don't store your documents after analysis. You can also black out your SSN before uploading if you're extra cautious. They have a detailed security explanation on their site that addressed my concerns.

Just wanted to update after trying taxr.ai for my complicated excess contribution situation. It was actually really helpful! The tool identified exactly which of my 1099-Rs were for the principal vs. earnings portions, and explained that I only owed taxes on the earnings part. It even pointed out that one of my 1099-Rs had the wrong code in Box 7 (should have been "P" but was "1"), and gave me instructions on how to properly report it despite the error. This saved me a potential audit headache. Definitely worth checking out if you're confused by the 402G excess contribution forms like I was!

If you're still getting nowhere with understanding these 1099-Rs, you might want to call the IRS directly. They can explain exactly how to handle your specific situation. I know calling the IRS sounds awful (I've spent HOURS on hold), but I recently used this service called https://claimyr.com and was shocked at how well it worked. You can see how it works here: https://youtu.be/_kiP6q8DX5c They basically hold your place in the IRS phone queue and call you when an agent picks up. I was dealing with a complex retirement account distribution issue last month and needed official guidance. Used Claimyr in the morning, got a call back after lunch, and the IRS agent walked me through exactly how to report my unusual distribution.

•How does this actually work? Does it just auto-dial the IRS repeatedly until it gets through? And do you still get to talk to a real IRS agent or is it some third-party service giving tax advice?

•Right, and I'm sure they're doing this out of the kindness of their hearts. Come on, there's no way this is legit. The IRS phone system is deliberately designed to be frustrating. No way some random service has "hacked" it. Sounds like a scam to get your phone number or payment info.

•It works by using an automated system that navigates the IRS phone tree and waits on hold for you. When an actual IRS agent picks up, their system calls you and connects you directly to that IRS agent. You're speaking with a real IRS employee, not a third party. No, it's definitely not free - they provide a valuable service by saving you from sitting on hold for hours. But considering I was able to get official IRS guidance on my retirement account issue without wasting half a day on hold, it was worth every penny to me. They don't ask for any tax info, just your phone number to call you back when an agent is on the line.

I need to eat my words and apologize about my skepticism. After struggling for THREE DAYS trying to reach the IRS about my 402G excess contribution situation, I gave in and tried Claimyr out of desperation. Got a call back in 1 hour 20 minutes with an actual IRS agent on the line. The agent confirmed that for 402G excess contributions, you do NOT need to amend your prior year return, and the 1099-R with the "P" code is just informational and not taxable again. Saved me from making a big mistake on my return AND from wasting more days trying to get through to the IRS. Sometimes being proven wrong is actually a good thing!

Quick reminder for everyone dealing with 402G excess contribution issues: the 2024 401k contribution limit is $23,000 (or $30,500 if you're 50+). If you're changing jobs this year, make sure you track your contributions across employers to avoid going over! My financial advisor told me an easy way to avoid this problem is to use a spreadsheet to track your contributions from each employer. Also, let your new employer's HR know if you've already contributed at a previous job that year.

•Do those limits apply to both Traditional and Roth 401k combined? Or can I do $23,000 in Traditional and another $23,000 in Roth? Also, does the employer match count toward the limit?

•The $23,000 limit applies to your combined Traditional and Roth 401k contributions - it's a total limit for all your elective deferrals. So you can split it however you want between Traditional and Roth, but the total can't exceed $23,000 (or $30,500 if you're 50+). Good news though - employer matching contributions don't count toward this limit! They fall under a separate, much higher limit (the "415(c) limit") which is $69,000 for 2024. This higher limit includes all contributions to the plan (your elective deferrals plus employer contributions).

Has anyone here actually looked at the codes in Box 7 of your 1099-Rs? Mine has code "E" which I can't figure out what it means. The IRS website is so confusing on this. Anyone know if that's the right code for excess contributions?

•Code "E" actually means distribution under a QDRO (qualified domestic relations order), which is usually for divorce situations. For excess contributions, you should normally see code "P" for principal or code "8" for earnings on excess contributions. You might want to contact your plan administrator because they may have coded your 1099-R incorrectly.
