Code 420 on transcript - examination or audit? Need clarity!
My transcript just updated with code 420 and has been stuck there for days now. Been reading different things online - some say its just a simple review others say full blown audit. Getting anxious about what this actually means for my return.

Code 420 indicates that your return has been selected for examination. This could mean anything from a correspondence audit (mail audit) to a more detailed review. The best thing to do is wait for an official IRS notice which will explain exactly what they need from you. Don't panic - many 420 codes are resolved through simple document verification.

•Typically 30-90 days, but could be longer depending on what they're reviewing and current backlog situation

Hey guys instead of stressing about codes, I've been using taxr.ai to analyze my transcripts. It costs $1 but totally worth it - gives you super specific timeline predictions and explains exactly whats happening. Been way more helpful than trying to decode these numbers myself https://taxr.ai

Had this last year. Call the IRS examination department directly at 866-xxx-xxxx. Sometimes they can tell you exactly what triggered it

Code 420 can be stressful but try not to worry too much! In my experience, it's usually something minor like income verification or document matching. The IRS will send you a letter (CP2000 or similar) explaining exactly what they need. Keep all your tax documents handy and respond promptly when you get the notice. Most of these resolve quickly once you provide the requested info.

•This is really reassuring to hear! I've been spiraling a bit since seeing that code pop up. Do you remember roughly how long it took from when the code first appeared to when you got the letter? Just trying to get a sense of the timeline so I know what to expect.

Code 420 is definitely nerve-wracking when you first see it! I went through this exact situation about 6 months ago. The code appeared on my transcript on a Wednesday, and I got the CP2000 notice in the mail exactly 12 days later. In my case, they were questioning some 1099 income that didn't match what I reported. I gathered my documents, responded within the 30-day window, and my refund was released about 5 weeks after I sent my response. The waiting is the hardest part, but most of these examinations are really straightforward once you know what they're looking for. Hang in there!

•Thanks for sharing your timeline! 12 days for the letter and 5 weeks after response is super helpful to know. I'm on day 4 since the code appeared so hopefully I'll hear something soon. Did you have to provide a lot of documentation or was it pretty straightforward once you knew what they wanted?

I'm dealing with the exact same thing right now! Code 420 showed up on my transcript 3 days ago and I've been checking it obsessively ever since. Reading through everyone's experiences here is actually making me feel a lot better - sounds like it's usually not as scary as it initially seems. Really appreciate everyone sharing their timelines and outcomes. Guess I just need to be patient and wait for that letter to arrive!
