The Common Types of IRS Notices
and What They Mean
IRS notices fall into several broad categories, each requiring a specific response. Treating a routine adjustment letter the same as an Intent to Levy can trigger devastating financial consequences and missed deadlines. We leverage our decades of inside experience to immediately identify the true threat level of your letter and deploy the right strategic defense.
Notices About Changes to Your Account:
Information Requests
Common Notice Numbers:
- CP2000

What They Mean:
CP2000 (Underreporter Inquiry):
This is one of the most common notices. It means the income or deductions you reported on your tax return don't match the information reported to the IRS by third parties (like employers, banks, or brokers). The IRS proposes changes to your tax, penalties, and interest.
CP2501 (Information Requests):
The IRS needs more information to process your return or verify certain claims.
CP01A (Identity Verification):
A notice related to suspected identity theft involving your Social Security number.
CP507 (Information Request):
This notice informs you of specific adjustments, unresolved penalties, or escalated actions on your tax account that require your immediate attention to prevent further bureaucratic enforcement.
What They Mean to Taxpayers/Business Owners:
These notices are not necessarily an audit, but they require a careful review and often a response within a specific timeframe (usually 30 days). Disagreeing without proper documentation can lead to a formal audit or automatic assessment.
How Saenz Tax Resolutions Helps:
We review the notice, compare it to your records, and determine the correct response. We can gather the necessary documentation, write a formal response to the IRS, and represent you if the matter escalates to an audit, ensuring you don't inadvertently admit to anything or miss deadlines.
Notices About Unpaid Taxes:
Collection Notices
Common Notice Numbers:
- CP14
- CP504
- LT11
- Letter 1058
- CP501
- CP503
What They Mean:
CP14 (Balance Due):
A bill for unpaid taxes, often for a small balance due after filing your return.
CP501/CP503 (Reminder of Balance Due):
Subsequent reminders that your tax is still unpaid, often with increasing interest and penalties.
CP504 (Notice of Intent to Levy):
This is a serious notice, indicating the IRS intends to levy (seize) your state tax refund and potentially other assets if you don't pay or respond.
LT11/Letter 1058 (Final Notice of Intent to Levy):
This is the
final warning before the IRS can legally garnish your wages, seize bank accounts, or take other collection actions. It typically grants you the right to a Collection Due Process (CDP) hearing.
What They Mean to Taxpayers/Business Owners:
These notices indicate escalating IRS enforcement. Ignoring them will lead to wage garnishments, bank levies, or even property seizures. Time is of the essence.
How Saenz Tax Resolutions Helps:
We act immediately to stop or prevent enforced collection actions. We analyze your financial situation to determine the best resolution (Installment Agreement, Offer in Compromise, Currently Not Collectible status) and negotiate directly with the IRS to establish a manageable payment plan or resolve the debt entirely.These notices are not necessarily an audit, but they require a careful review and often a response within a specific timeframe (usually 30 days). Disagreeing without proper documentation can lead to a formal audit or automatic assessment.
Notices About Audits:
These indicate the IRS is formally examining your tax return.
Common Notice Numbers:
- Letter 2000
- Letter 3219
- CP75
- CP75A
- CP2000
What They Mean:
Letter 2000/Letter 3219 (Audit Notification):
These letters inform you that your return has been selected for examination and request specific documents or information.
CP75/CP75A (Audit for Earned Income Tax Credit):
Specific audit notices for claims related to the Earned Income Tax Credit.
What They Mean to Taxpayers/Business Owners:
This is a formal inquiry. The IRS believes there may be an error or discrepancy on your return. Mismanaging an audit can lead to significant additional tax liabilities, penalties, and interest.
How Saenz Tax Resolutions Helps:
We provide comprehensive audit representation. We prepare you for the audit, organize and present your documentation, respond to all IRS inquiries, attend all meetings with the auditor, and advocate on your behalf to minimize any potential tax increases or penalties.
Notices Regarding
Penalties & Interest
These explain specific penalties
or interest charges
Common Notice Numbers:
- CP11
- CP16
- CP20
- CP30
- CP210
- CP220
What They Mean:
These notices detail penalties for issues like failure to file, failure to pay, underpayment of estimated tax, or accuracy-related penalties, along with associated interest.
CP11 (Changes to Your Tax Return - Balance Due):
This notice indicates the IRS found a miscalculation on your tax return, made corrections on your behalf, and you now owe a balance as a result of those adjustments.
CP16 (Changes to Your Tax Return - Refund Offset):
This notice informs you that the IRS corrected a miscalculation on your return and applied your resulting refund directly to other unpaid taxes or debts you currently owe.
CP20 (Return Adjustment - Balance Due):
This notice alerts you that the IRS made changes to your tax return—often due to a discrepancy between what you reported and what third parties reported— resulting in additional taxes owed.
CP30 (Estimated Tax Penalty):
This notice is issued to inform you that the IRS is charging you a penalty because you underpaid your estimated taxes throughout the year or did not pay them on time.
CP210 (Tax Return Adjustment - Business):
This notice informs you that the IRS made changes to your business tax return, either based on a request you submitted or their own internal review, outlining your new balance, penalty, or refund.
CP220 (Tax Return Adjustment - Business Balance Due):
This is a notification that the IRS made specific adjustments to your business tax account, resulting in a new balance due that now includes additional taxes, penalties, or interest.
What They Mean To Taxpayers/Business Owners:
While penalties and interest can significantly inflate your tax debt, they are sometimes abatable (removable) if you have "reasonable cause."
How Saenz Tax Resolutions Helps:
We analyze your situation to determine if you qualify for penalty abatement. We prepare and present a compelling case to the IRS based on their criteria for reasonable cause, leveraging our understanding of their internal policies to argue for the removal of penalties.
