Tax Audit

Tax Audit — what it means, how it works, and a real example, explained without the jargon.

What is Tax Audit?

An audit is an IRS review of your return to verify that the income, deductions, and credits you reported are accurate.

How it works

Most audits are simple correspondence audits handled entirely by mail — the IRS asks for documentation on one or two items. Field audits are rarer and more involved. Solid records are your best defense in either case.

A quick example

The IRS mails you a letter questioning a large charitable deduction. You send copies of your donation receipts, and the matter closes with no change.

What people get wrong

Audit odds are low for most filers, but they rise with big round-number deductions, large Schedule C losses, and unreported 1099 income. Keep receipts for at least three years.
