Understanding IRS Notices and Audits
What Is an IRS Notice?
An IRS notice is a formal letter issued to alert you of tax discrepancies, missing documents, or potential audit selections. Notices can vary in seriousness, from a simple balance due to a full investigation of your financials.
Common IRS Notices Include:
- CP2000 – Reported income doesn’t match W-2s or 1099s
- CP501 – Reminder of unpaid taxes
- CP3219A – Statutory Notice of Deficiency (possible audit)
What Is a Tax Audit?
A tax audit is an examination of your financial records to verify the accuracy of your return. It can be conducted by mail (correspondence audit), at an IRS office, or on-site at your place of business.
Difference Between Notice and Audit:
- Notice: May not require immediate action beyond clarification.
- Audit: Requires submission of detailed records and often professional representation.

What Triggers an IRS Audit?
IRS audits aren’t always random. Several red flags could increase your audit risk:
- Excessive deductions (especially home office or vehicle)
- Misreporting income
- High income relative to deductions
- Cash-intensive business operations
- Previous audit history
For a full breakdown of common triggers, check the IRS Audit Techniques Guide.
Steps to Take When You Receive an IRS Notice
- Read the Notice Carefully
- Identify the notice type (code), what the IRS wants, and your response deadline.
- Gather Documentation
- Collect W-2s, 1099s, bank statements, receipts, and relevant business records.
- Don’t Panic or Ignore It
- Delays can increase penalties. A timely response shows good faith and improves outcomes.
- Consult a CPA or Tax Professional
- IRS language can be complex. A CPA ensures your response is complete and strategic.
- Respond Professionally
- Submit all required documents and a clear explanation if requested. Never admit guilt or submit unnecessary paperwork.

What Happens During a Tax Audit?
If selected for a full audit, here’s what to expect:
- Notification: You’ll receive a detailed letter outlining what’s being reviewed.
- Preparation: You’ll need to gather and organize receipts, tax returns, payroll reports, depreciation schedules, etc.
- Representation: You can have your CPA represent you in discussions with the IRS.
- Interview: The IRS may ask about your business structure, deductions, and income sources.
A well-prepared audit can limit exposure and prevent future scrutiny. IRS Publication 556 provides an overview of audit procedures.
