IRS Notice CP2000

Internal Revenue Service (“IRS”) Notice CP2000 is a computer-generated notification of additional tax for taxpayers who filed a federal individual income tax return. IRS Notice CP2000 effectively operates as an IRS audit of underreported income and is administered by the IRS AUR program to flag potential underreporters. CP2000 notices are triggered when the IRS receives additional information from third parties reporting taxable income earned under the taxpayer’s social security number (or other tax identification number) that does not match the income information reported on the taxpayer’s tax return or amended tax return. The CP2000 notice also contains a proposed amount due.

The first step a taxpayer should take after receiving a CP2000 letter is to identify the notice response due date. Failure to respond by this date will limit your rights to challenge the proposed assessment. Once the deadline is identified, the taxpayer should carefully review the CP2000 notice to understand the basis for each proposed change identified by the IRS. For example, the CP2000 notice could propose a change to income for an item left off the taxpayer’s return, or the IRS could propose a decrease to an expense item as the third party reported the expense as less than the taxpayer reported it on their return.

Once the taxpayer understands the proposed changes, the taxpayer must determine whether to accept or challenge the proposed changes. The taxpayer should compare their tax documents (such as IRS forms w-2 or 1099) with the proposed changes outlined in the CP2000 notice. If the taxpayer’s documents agree with the proposed IRS changes, then the taxpayer should complete the response section of the notice and return it to the IRS. The taxpayer can then either pay the full amount of tax or request an installment agreement or payment plan.

If the taxpayer’s documents do not agree with the proposed changes outlined in the CP2000 notice, the taxpayer is entitled to challenge the proposed changes. The taxpayer can challenge the proposed changes by submitting a response to the IRS. This response can be mailed to the IRS at the address on the CP2000 notice or transmitted to the fax number listed on the CP2000 notice. The taxpayer’s response should include an explanation of the taxpayer’s position, supporting documentation, and a copy of the CP2000 notice. The supporting documentation can range from forms received from financial institutions showing the correct amount of income received to self-prepared schedules and the underlying documents supporting the numbers on the self-prepared schedule.

The IRS will review the taxpayer’s CP2000 response and, through a separate IRS letter, either reverse or uphold the proposed assessment. If the IRS upholds the proposed assessment, the taxpayer will receive a separate Statutory Notice of Deficiency. This notice allows the taxpayer to further challenge the proposed assessment in U.S. Tax Court by filing a Petition within 90 days of the issue date of the Statutory Notice of Deficiency.
