Correspondence audit — conducted by mail for a single issue like a missing form Office audit — you visit an IRS office to review specific items with an examiner Field audit — an IRS agent visits your home or business for a broader examination Most audits are correspondence audits — field audits are less common

Statute of Limitations

The IRS generally has 3 years from the filing date to audit a return This extends to 6 years if gross income is understated by more than 25% There is no time limit for fraudulent returns or if no return was filed You can agree to extend the statute but are not required to do so

No change — the IRS accepts your return as filed and closes the case Agreed — you accept the IRS findings and pay additional tax, interest, and penalties Unagreed — you disagree with the findings and can request an appeals conference In some cases the IRS may issue a refund if the audit uncovers an overpayment

IRS Appeals is an independent office that reviews disputed audit findings You typically have 30 days from the examination report to file a written protest Appeals conferences are informal and often result in compromise settlements If appeals fails, you can petition U.S. Tax Court before paying the disputed amount

Reducing Your Audit Risk

Report all income — the IRS matches every W-2, 1099, and K-1 against your return Keep thorough documentation for deductions, especially charitable and business File accurate, complete returns on time — amended returns do not increase audit risk Use a qualified tax preparer for complex situations to reduce errors
