Background: How a Tax Audit Letter Originates

A tax audit letter marks the beginning of an IRS review of your filed tax return. The IRS uses automated systems and manual reviews to identify discrepancies, unusual claims, or data mismatches that could indicate errors or fraud. For example, claiming unusually high business expenses or deductions that don’t align with your reported income can trigger a tax audit. When the IRS decides to review your return more closely, they send this official letter to notify you.

What Does a Tax Audit Letter Include?

The letter clearly specifies:

  • The tax year under audit
  • Which parts of your return need explanation or proof
  • Types of documentation you need to provide (e.g., receipts, bank statements, contracts)
  • Instructions on how to respond and deadlines (usually around 30 days)
  • Contact details for your assigned IRS examiner

Ignoring this letter or missing response deadlines can lead to penalties or additional tax assessments.

Real-World Example

Imagine you filed your 2022 tax return with a substantial charitable donation deduction. The IRS computer flags this as unusually high relative to your income. They send you a tax audit letter asking for donation receipts or acknowledgments. By gathering and submitting these documents promptly, you can resolve the audit smoothly without penalties.

Who Is Likely to Receive a Tax Audit Letter?

While less than 1% of taxpayers are audited annually, certain groups have a higher chance of receiving a tax audit letter:

  • Business owners, freelancers, and self-employed individuals due to complex income and deductions
  • Taxpayers with high incomes or substantial deductions
  • Those with data discrepancies between their filings and IRS records
  • Random selections intended to ensure fairness

It’s important to understand that receiving a tax audit letter does not imply wrongdoing; sometimes it’s a routine check.

Tips for Handling a Tax Audit Letter

  • Stay Calm: Receiving the letter does not mean you are in trouble.
  • Read Carefully: Understand exactly what documentation and information the IRS requests.
  • Gather Accurate Documentation: Provide only what is requested to avoid confusion.
  • Respond Promptly: Meet the deadline to prevent further complications.
  • Seek Professional Help If Needed: Tax professionals like CPAs or enrolled agents can assist with complex audits.
  • Keep Records: Make copies of all correspondence and submitted documents.

Common Misconceptions and Mistakes

  • Believing the audit letter is a criminal accusation (It’s not—it’s part of normal tax enforcement.)
  • Ignoring or delaying your response, which can worsen the situation
  • Overloading the IRS with unsolicited documents, which can complicate the audit
  • Assuming all IRS contact is via phone or email scams; official IRS audit communications come through mail
