Frequently asked questions.

No. A CP2000 is an underreporter inquiry — the IRS is saying the income reported to them doesn't match your return. It's not an audit and not a final bill, but it does have a response deadline, usually about 30 days.

You can try — but a general AI tool or blank template doesn't read your specific notice, doesn't know which of your figures the IRS is questioning, and won't tell you whether the IRS is even right. It also won't format the response the way the IRS expects. NoticeFiled is purpose-built for exactly this one job, so you're not guessing whether you got it right on a deadline that matters.

If our analysis shows the IRS is right, we'll tell you plainly, and your response letter will reflect that so you avoid extra penalties. Knowing you owe the right amount is just as valuable as disputing a wrong one.

No, and that's intentional. You stay in control. We give you the analysis and a ready-to-submit letter; you review, sign, and submit it yourself.
