What Are IRS Notices?
IRS notices are formal letters issued by the Internal Revenue Service to notify taxpayers of issues such as underreported income, identity verification, or unpaid taxes. Each notice is identified by a number—like IRS NOTICE CP2000 or IRS NOTICE CP3219A—which indicates the specific issue and required action.
If you receive a notice, it’s important to read it carefully, note the date, and take appropriate action before the due deadline to avoid additional penalties.
Types of IRS Notices (and What They Mean)
CP501, CP503, and CP504
These notices alert you of a balance due on your tax account. CP504 is more urgent, warning that the IRS may take collection action.
CP2000
IRS CP2000 notice is sent when your reported income does not match data from employers or financial institutions. This usually results in a proposed adjustment to your tax return.

Also known as a Statutory Notice of Deficiency. Indicates the IRS plans to assess additional tax unless you respond within 90 days.
CP90 and CP297 / CP91 and CP298
Final notices before wage garnishments or levies on Social Security benefits are initiated. These require urgent attention.
LETTER 1058 / LETTER 11 / LETTER 3172
These letters are associated with liens and levies. They’re part of the IRS's collection process and signal that your case is escalating.
CP523
Sent when you’ve defaulted on an existing IRS installment payment plan.
What to Do When You Receive an IRS Notice
Step 1: Read the Notice Carefully

- Ensure your mailing address is updated in your IRS account.
Step 3: Respond by the Deadline
- Most notices require action within 30–90 days.

Step 4: Get Help from a Dallas Tax Professional

Why IRS Notices Are Sent
The IRS issues notices and letters for several reasons, ranging from simple mistakes on a return to more serious issues, such as unpaid taxes or suspected identity theft. Understanding the common reasons behind these notices can help you respond appropriately and avoid future problems.
1. Filing Errors
One of the most frequent reasons taxpayers receive IRS notices is due to errors or inconsistencies on their tax returns. This might include:
- Misspelled names or mismatched Social Security numbers
- Omitting income that was reported by employers or financial institutions
- Miscalculating tax owed or credits claimed
- Filing with the incorrect status or dependent information
When the IRS detects discrepancies between your return and the information it receives from third parties (like W-2s or 1099s), it will send a notice to correct or clarify the issue. Notices such as CP2000 are commonly sent for unreported income.
2. Unpaid Taxes
If the IRS determines that you owe additional taxes, whether due to underpayment, late filing, or failure to file altogether, it will begin issuing a series of balance-due notices. These may include:
- CP14 – First notice of unpaid taxes
- CP501 or CP503 – Reminders that a balance is still due
- CP504 – Final notice before collection actions begin
Remember: Ignoring these notices can lead to serious consequences, including interest accrual, penalties, wage garnishment, or liens. It’s essential to respond promptly or work with a tax professional to resolve your balance.
3. Identity Verification
To combat tax fraud and identity theft, the IRS sometimes issues letters asking taxpayers to verify their identity before processing a return. These letters are sent when suspicious activity or inconsistencies are detected, such as:
- Unusual filing locations or methods
- Duplicate returns using the same Social Security number
- Returns claiming refunds that seem excessive
The most common notices related to identity verification include Letter 4883C and Letter 5071C. Failing to respond can delay your tax refund or prevent your return from being processed. The IRS typically provides instructions for verifying your identity online or by phone, and timely compliance helps ensure your account is secure.
