IRS Notice & Statutory Examination FAQ
What should I do immediately after receiving an IRS notice?
First, verify the notice code in the top or bottom right corner (e.g., CP2000, CP14, CP504). Note the response deadline immediately, as IRS statutory deadlines (typically 30 calendar days) are strictly enforced. Never ignore an IRS letter — proposed adjustments become final binding assessments if left unanswered.
What is IRS First-Time Penalty Abatement (FTA)?
First-Time Abatement (FTA) is an administrative waiver authorized under Internal Revenue Manual (IRM) 20.1.1.3.6.1. It allows qualifying taxpayers with a 3-year clean compliance history to completely remove failure-to-file and failure-to-pay penalties without needing to establish reasonable cause.
Is a CP2000 notice an official tax audit or bill?
No. A CP2000 is an automated underreporter (AUR) proposed adjustment letter, not an official audit or statutory bill. It informs you that information reported by third parties (such as 1099s or W-2s) does not match what was filed on your return. You have the statutory right to disagree and provide supporting documentation.
What happens if I miss the 30-day CP2000 or LT11 response window?
Missing the response window triggers a Statutory Notice of Deficiency (90-day letter). Once that occurs, your only formal avenue to challenge the proposed tax without paying it first is filing a formal petition with the United States Tax Court within exactly 90 days.
