IRS CP2000 Notice Not Resolved? The Notice of Deficiency and the 90-Day Tax Court Deadline

A CP2000 is the IRS’s proposal to change your return because income reported by a third party, such as on a Form 1099 or W-2, does not match what you reported; it is not a bill or a final determination. If you do not reply by the date on the notice, or no agreement is reached, the next step is a statutory notice of deficiency, and from its mailing you generally have 90 days to petition the U.S. Tax Court, a deadline the IRS cannot extend.

Answering the CP2000 first

Reply by the date listed on the notice. IRS Tax Topic 652 asks for a response within 30 days of the notice date, or 60 days if you live outside the United States, for a quick resolution. The response form lets you agree, or disagree with a signed statement and supporting documents; if you need more time, IRS Publication 5181 says to call the number on the notice.

Publication 5181 asks you to address every item and identify the line or schedule where you reported each amount; if an amount sits inside a larger total, give a breakdown of that total. If the form itself is wrong, ask the payer for a corrected document or a statement explaining the error, and send a copy with your reply. Interest keeps accruing on unpaid balances; Publication 5181 says paying the full proposed tax, penalties and interest as a designated section 6603 deposit stops that accrual.

A Form 1099-R reports both a gross distribution and a taxable amount, so the dispute can be about what part is taxable, not whether money changed hands. Our Braun case analysis explains how the court found taxable income from a life insurance policy converted to term coverage with no check paid out.

No reply or no agreement: the statutory notice of deficiency

Publication 5181 says that if an agreement is not reached, or you do not respond or get an extension, the IRS will send a statutory notice of deficiency by certified mail; before then, it says, you can ask to speak with the examiner and then a manager. Section 6212 authorizes that notice by certified or registered mail, and a notice mailed to your last known address is sufficient. Our old-address guide explains that rule.

For income reported by third parties, the IRS’s CP3219A notice is that statutory notice. If you agree, you sign the enclosed Form 5564 waiver. You can still send the IRS information during the 90 days, but the IRS says: “We can’t extend the time you have to file a petition with the U.S. Tax Court if you choose to do so.”

The 90-day petition deadline

Under section 6213(a), you may petition the Tax Court within 90 days after the notice is mailed, or 150 days if the notice is addressed to a person outside the United States. A Saturday, Sunday or District of Columbia legal holiday does not count as the last day, and a petition filed by the last date the IRS specifies in the notice is treated as timely. For income tax, the IRS generally cannot assess the deficiency or levy for it until that period ends or, if you petition, until the Tax Court’s decision is final.

If you neither agree nor petition, the CP3219A page says the IRS will assess the proposed changes and send a bill.

If neither the income tax deficiency in dispute, counting any penalties and additions to tax in dispute, nor any claimed overpayment exceeds $50,000 for any one taxable year, section 7463 lets you elect a small tax case, with the Tax Court’s concurrence. The decision cannot be reviewed by any other court and is not precedent for any other case.

In Tax Court, the IRS can rely on the Form 1099 unless you raise a reasonable dispute and cooperate

Section 6201(d) sets when the IRS needs more than the form. In a court proceeding, the IRS must produce reasonable and probative information beyond a third party’s information return if you assert a reasonable dispute about an item of income reported on it and have fully cooperated with the IRS, including giving it, within a reasonable time, access to witnesses, information and documents within your control as reasonably requested.

In Braun, a small tax case, the taxpayer attached a note to his return saying he was not reporting the Form 1099-R amount and said in his petition that he received nothing from the insurer, but the court found no evidence supporting a reasonable dispute about the form’s accuracy, so the IRS could rely on it. Our reading: the CP2000 reply is where that dispute starts. A corrected form, a payer’s statement, a breakdown tying the amount to your return or the payer’s own basis figures can support a reasonable dispute; disagreement alone did not in Braun.
