What Are IRS CP-Series Notices?

IRS CP-Series Notices are standardized letters issued by the Internal Revenue Service to address issues related to individual or business tax returns. These notices are commonly sent for unpaid balances, missing payments, or discrepancies between information reported on a tax return and data received by the IRS from third parties such as employers or financial institutions.

CP notices typically follow a progressive sequence, meaning the level of urgency increases if earlier notices are not resolved. Understanding which notice you have received helps determine the seriousness of the situation and the appropriate response.
