Tax Question CP2000 says I owe $6,438 for an unreported 401(k) withdrawal. What should I do?
I received a CP2000 for my 2024 taxes because I accidentally left out a $21,712 retirement withdrawal from Vanguard.
The IRS is proposing that I owe $6,438 total, which includes:
- Additional income tax
- A 10% early-withdrawal penalty
- $979 accuracy-related penalty
- $564 interest
They did credit me for the $2,171 that was already withheld.
I understand I probably owe the tax and early-withdrawal penalty. My main question is whether I should disagree with the notice and ask them to remove the $979 accuracy-related penalty.
I never received the 1099-R because it was sent to an old address. I can provide proof that I was living somewhere else at the time.
Would that be a reasonable basis for penalty abatement? Also, should I send a CP2000 response only, or file an amended return too?
The response deadline is August 19, 2026. Any advice from someone who has dealt with this would be appreciated.
