A tax audit is a review or examination of a taxpayer’s accounts and financial information by the IRS (or state tax agency) to ensure that the information reported on a tax return is accurate and complete. Most taxpayers are never audited. Keeping records that support the information on your return is the best way to prepare in case you’re contacted by a tax agency.
🧾 Why Audits Happen
Audits may be triggered by:
- Math errors or mismatched income documents (like W-2s or 1099s)
- Unusually high deductions or credits
- Random selection by IRS algorithms
- Related audits (e.g., business partners or investors)
🔍 Types of Audits
- Correspondence Audit
- Done by mail
- Usually for simple issues (e.g., missing documents)
- Office Audit
- Conducted at an IRS office
- Involves more detailed questions and documentation
- Field Audit
- Done at the taxpayer’s home, business, or accountant’s office
- Most comprehensive type
📅 What to Expect
- The IRS will send a letter explaining what they’re reviewing
- You’ll be asked to provide supporting documents (receipts, bank statements, etc.)
- You can respond yourself or authorize a tax professional to represent you
✅ How to Prepare
- Keep organized records for at least 3 years
- Respond promptly and politely to IRS requests
- Know your rights: You can appeal audit findings if you disagree
🛠️ Example:
A taxpayer claims $15,000 in charitable donations but doesn’t provide receipts.
The IRS may audit the return and request proof. If the taxpayer can’t verify the donations, the deduction may be disallowed.
