IRS Notice
Official correspondence from the IRS regarding your tax account, such as balance due, adjustments, or collection actions.
Full Definition
An IRS notice is official mail from the Internal Revenue Service regarding your tax account. Notices can inform you of changes to your return, request additional information, notify you of a balance due, or warn of pending collection actions. Each notice has a specific code (like CP14, CP504, or LT11) that indicates its purpose. It's important to read notices carefully, respond by the deadline if required, and keep copies for your records. Not all IRS notices require action, but many have strict deadlines.
