What to check first (before you act)

Goal and timeline

Before assuming an audit is happening, consider your overall tax strategy. Are you expecting any particular scrutiny based on recent life events (e.g., starting a business, significant investment gains)? Have you filed accurately and on time in the past? Understanding your own tax situation and history provides context for any IRS communication.

Current cash flow

An audit doesn’t immediately require a large sum of money, but it can lead to additional tax liabilities or penalties. Assess your current financial situation to understand if you could manage any unexpected tax bill. This includes having a clear picture of your income, expenses, and savings.

Emergency fund or safety buffer

A robust emergency fund is crucial for any unexpected financial event, including a tax audit. If you don’t have one, or if it’s depleted, this is a sign to prioritize building it, regardless of audit concerns. A healthy buffer can provide peace of mind.

Debt and interest rates

If an audit results in additional taxes owed, understanding your current debt obligations and their interest rates will help you prioritize repayment strategies. High-interest debt, in particular, can quickly erode your financial health.

Credit impact

While an audit itself doesn’t directly impact your credit score, an unpaid tax liability resulting from an audit can lead to tax liens, which do affect credit. Proactive communication with the IRS and timely payment of any owed amounts are key to avoiding this.

Step-by-step (simple workflow)

Step 1: Receive a communication from the IRS

What to do: Carefully read any letter or notice you receive from the IRS. Note the date, the notice number (if any), and the specific request.
What “good” looks like: The communication is a standard notice about a discrepancy, or a request for clarification on specific items, and it arrived via U.S. Mail.
A common mistake and how to avoid it: Immediately panicking and assuming the worst. Avoid this by staying calm, verifying the sender, and understanding that most IRS notices are not audits.

Step 2: Verify the authenticity of the notice

What to do: Check the return address and the IRS notice number against official IRS resources. You can also call the IRS directly using the number on their official website (not one provided in a potentially suspicious letter).
What “good” looks like: The notice is legitimate and originates from the IRS, typically through U.S. mail.
A common mistake and how to avoid it: Responding to unsolicited emails, phone calls, or texts claiming to be from the IRS. The IRS states they will not initiate contact this way.

Step 3: Identify the type of notice

What to do: Determine if the notice is a simple inquiry, a proposed adjustment, or a formal audit notification.
What “good” looks like: You understand the IRS’s specific concern and what action, if any, is required from you.
A common mistake and how to avoid it: Misinterpreting a routine inquiry as a full-blown audit. Avoid this by reading the notice carefully and researching common IRS notice types.

Step 4: Review your tax return and supporting documents

What to do: Gather the tax return in question and all supporting documentation (receipts, W-2s, 1099s, bank statements, etc.).
What “good” looks like: You have all your records organized and can easily cross-reference them with your filed return.
A common mistake and how to avoid it: Not having adequate records to support your tax filings. This makes responding to any IRS request much more difficult.

Step 5: Understand the IRS’s specific request

What to do: Pinpoint exactly what information the IRS is asking for or what discrepancy they have identified.
What “good” looks like: You clearly understand the scope of the IRS’s inquiry.
A common mistake and how to avoid it: Making assumptions about what the IRS wants instead of reading the notice.

Step 6: Respond by the deadline

What to do: Provide the requested information or documentation by the date specified in the IRS notice.
What “good” looks like: Your response is complete, accurate, and sent within the timeframe.
A common mistake and how to avoid it: Missing the deadline, which can lead to further penalties or actions.

Step 7: Consider professional help

What to do: If the notice is complex, involves significant amounts, or you feel overwhelmed, consult a qualified tax professional (CPA, Enrolled Agent, or tax attorney).
What “good” looks like: You have expert guidance to navigate the IRS process.
A common mistake and how to avoid it: Trying to handle a complex audit alone if you lack tax expertise, potentially making costly errors.

Step 8: Cooperate with the IRS

What to do: Be truthful, organized, and timely in your interactions with the IRS.
What “good” looks like: A smooth and efficient resolution of the IRS’s inquiry.
A common mistake and how to avoid it: Being evasive or providing incomplete information, which can prolong the process and raise further suspicion.

Common mistakes (and what happens if you ignore them)

Mistake	What it causes	Fix
Ignoring IRS notices	Escalation of the issue, potential penalties, interest, liens, and wage garnishment.	Respond promptly to all IRS correspondence by the stated deadline.
Believing IRS scams	Identity theft, financial loss, and still owing taxes to the IRS.	Never share personal information via phone, email, or text from unsolicited contacts claiming to be the IRS. Verify through official channels.
Not keeping good records	Inability to support deductions or income, leading to disallowed claims and audits.	Maintain organized financial records for at least three years after filing (longer in some cases).
Assuming a notice is an audit	Unnecessary stress and potential overreaction.	Carefully read the notice to understand its specific purpose; most are not audits.
Providing incomplete or inaccurate info	Extended IRS review, potential penalties, and a higher likelihood of a full audit.	Be thorough and honest when responding to IRS requests. Consult a tax professional if unsure.
Not responding by the deadline	Automatic assessment of taxes, penalties, and interest without your input.	Note all deadlines on IRS notices and prioritize meeting them.
Hiring an unqualified tax preparer	Errors on your return that can lead to audits or penalties.	Choose a credentialed tax professional (CPA, Enrolled Agent) with a good reputation.
Failing to report all income	Underreporting is a major audit trigger, leading to back taxes, penalties, and interest.	Accurately report all income from all sources, including freelance work, investments, and side hustles.
Claiming excessive or unsubstantiated deductions	These are common audit triggers; the IRS will ask for proof.	Only claim deductions for which you have legitimate expenses and supporting documentation.
Not understanding audit types	Mismanaging expectations and response strategy.	Familiarize yourself with different IRS audit methods (mail, office, field) to prepare appropriately.

Decision rules (simple if/then)

• If you receive a letter from the IRS via U.S. Mail, then open and read it carefully because it’s the official way the IRS communicates.
• If the letter demands immediate payment or threatens arrest, then it’s likely a scam because the IRS does not operate this way.
• If the notice is a CP2000 notice, then it means the IRS found a discrepancy between your return and information reported by third parties, and you need to respond with documentation.
• If you are unsure about the legitimacy of an IRS notice, then contact the IRS directly through their official website or a verified phone number because this avoids scams.
• If the IRS notice is a formal audit notification (e.g., Letter 2141 for a field audit), then you should take it seriously and consider seeking professional tax advice because audits require careful handling.
• If you have extensive or complex financial transactions, then you are at a higher risk for an audit, so ensure your records are impeccable.
• If you claimed significant deductions or credits that are unusual for your income level, then be prepared to provide detailed substantiation because these can be audit triggers.
• If you’ve been audited in the past and found to have significant issues, then you may be subject to increased scrutiny in future audits because the IRS may flag your return.
• If you are contacted by phone or email claiming to be the IRS asking for personal or financial information, then hang up or delete the message because this is a common scam tactic.
• If you decide to respond to an IRS notice yourself, then ensure your response is accurate, complete, and submitted by the deadline because this is crucial for a positive resolution.
• If your tax return was prepared by a tax professional, then review it thoroughly before signing because you are ultimately responsible for its accuracy.
• If the IRS proposes changes to your tax liability, then you have the right to appeal, so understand your options and consider professional guidance.
