A CP2000 is a proposal — not a final tax bill. The IRS computer matched a 1099 or W-2 to your return and flagged a mismatch. Most CP2000s are wrong, partially wrong, or fixable with a single supporting document.You can read through the wizard now; it produces the document once its rules are reviewed by a licensed attorney.
The IRS CP2000 response template is waiting for a licensed attorney to review its rule data. Until then SynthCounsel does not produce this document, so answering the questions will not give you one.
You can still read through the questions to see what it asks and what to gather.
Silence is the worst response to a CP2000. The IRS will issue a Notice of Deficiency under IRC § 6212 and assess the proposed tax, interest, and any penalties — and your low-cost remedy (Tax Court petition under IRC § 6213(a)) closes 90 days later.
Send by USPS Certified Mail, Return Receipt Requested to the IRS address on your notice. Keep a copy. Log the tracking number. The IRS typically replies in 60–90 days with a corrected notice (no change), a revised proposal, or a final Notice of Deficiency.
Complex CP2000 disputes — multiple years, large amounts, fraud allegations, or business returns — warrant a CPA or tax attorney. Look for an Enrolled Agent (EA) or attorney admitted to practice before the U.S. Tax Court. SynthCounsel is not a law firm or accounting firm.
