Lost my envelope - Where do I mail signed CP2000 Notice for IRS?

Thanks for the info! Quick followup q - if I'm agreeing with the CP2000 but want to explain some circumstances about why the income wasn't reported, should I still just sign the response form or should I include a letter? And do I need to send anything else besides the signed form and possibly my explanation?

You can absolutely include a letter explaining your circumstances. While it won't change the amount you owe if you're agreeing to the adjustment, it's good to have your explanation on record. This is especially helpful if a similar issue happens in the future. You should include the signed response form, your explanation letter, and any supporting documentation that helps explain your situation. You don't need to include another copy of your tax return unless they specifically requested it.

Does taxr.ai help with other IRS notices too? I just got something called a CP11 and I'm totally confused about what to do next.

I'm a little skeptical about using some random website with my tax info. How do you know its secure? And is there a cost for using it or is it one of those "free until you need the actual help" kind of things?

Yes, it helps with pretty much any IRS notice! You just upload your document and it explains exactly what the notice means and what steps you need to take. The CP11 is a math error notice, so it would break down what the IRS thinks is wrong and your options for responding. Their security is actually really solid - they use bank-level encryption and don't store your documents after analysis. I was concerned about that too, but they explain their security measures clearly on the site. And while there is a cost for the full analysis, it's way less than what I'd have paid a tax pro just to tell me where to mail my form.

How does this actually work? Do they somehow jump you ahead in the IRS phone queue or something? That seems too good to be true.

Yeah right. Nothing can get through to the IRS faster. I've tried calling them for weeks about MY CP2000 and can't get through. No way some service can magically make the IRS call you back when they won't even answer their own phones.

They don't jump the queue, they basically wait on hold for you. Their system navigates the IRS phone tree and waits in the queue, then when an agent finally answers, they call and connect you. It's basically like having someone else wait on hold instead of you having to do it yourself. It definitely works. I was skeptical too until I tried it. The IRS actually did call me back, and I was able to speak with an agent who confirmed everything about where to send my forms. The whole process took less than an hour total instead of the multiple attempts I was making trying to get through on my own.

Thanks for the clear answer! I'm definitely keeping copies of everything. Would you recommend sending it certified mail or priority mail? I just want some kind of tracking to prove I sent it before the deadline.

Priority Mail with tracking is good, but I'd actually recommend Certified Mail with Return Receipt. That gives you proof of exactly when it was delivered and who signed for it. It's a bit more expensive but worth it when dealing with the IRS. For something this important, the extra few dollars is definitely worth the peace of mind. The IRS doesn't always process mail immediately when they receive it, so having that delivery confirmation can save you if there's ever a dispute about whether you responded on time.

Is there a way to check if they've received and processed your response to a CP2000? I'm wondering if there's an online status checker or something similar.

You can check the status through the IRS website at irs.gov using their "Get My Payment" tool if you've made a payment, or you can call the AUR line directly. However, it typically takes 4-6 weeks for them to process CP2000 responses, so don't panic if you don't see an update right away. You can also create an account on irs.gov to view your tax account transcript, which will eventually show when they've processed your response and applied any payments. Just be patient - the IRS moves slowly but they do process everything eventually!

This is really helpful advice! I didn't realize the interest keeps accruing after the CP2000 is issued. Quick question - when you say use the IRS online payment system to calculate the current balance, do you mean the EFTPS system or is there a different tool on irs.gov? I want to make sure I'm looking at the right place to get the most up-to-date amount owed.
