Letter CP 2000 is sent to notify you that one or more items on your return don’t match what was reported to the IRS by third parties (e.g., employers or financial institutions).
This notice or letter may include additional topics that have not yet been covered here. Please check back frequently for updates.
The letter shows who reported the item that doesn’t match your return, the amount of the item, and explains how the item affects your tax return. Letter CP 2000 is not an IRS audit or a bill. The IRS is proposing to correct your return by adjusting the items listed in Letter CP 2000 unless you provide the IRS with information that shows why the amounts on your return are correct.
The IRS matches the information you reported on your tax return with information reported to IRS by third parties such as employers, banks, businesses, and others. If there is a discrepancy between the amount shown on your return and the amount reported to the IRS, Letter CP 2000 is sent to notify you of the difference, identify the third party who reported the amount in question, and propose adjustments to correct your return.
Read the letter and follow the instructions. Letter CP 2000 will show any amounts reported to the IRS by third parties that don’t match the amounts shown on your return. Compare the items listed in the Letter CP 2000 to the amounts you reported on your tax return to determine if your return was correctly filed or if an adjustment to your return is necessary. If you believe the amount reported by the third party to the IRS is incorrect or does not belong to you, you may need to contact the third party and ask that the item reported to the IRS be corrected.
Complete the form on page seven of your Letter CP 2000 to show whether you agree or disagree with the changes the IRS is proposing in the letter. If you agree, you do not need to amend your tax return. The IRS will make the adjustments detailed in the CP 2000. If you disagree, explain why you disagree and provide any documents or information that supports your position. Make sure to submit all documents and information to the IRS by the due date to the address in the letter. Don’t send original documents send copies. If you fax the information, include your name and Social Security number or Taxpayer Identification Number on each page. This will help the IRS match your documents with your file. After the IRS reviews your response, it may accept your return as originally filed, ask you to send more information, or send you a Letter 3219, Statutory Notice of Deficiency, a legal notice that the IRS has determined a deficiency in your income tax (balance due).
