Many taxpayers seem to believe that if the IRS doesn't call them in for an audit within six months after their return is filed, they are home free. The IRS has, at least, three years from the date your return was filed or due, whichever is later, to audit your return. Here are some easy ways to avoid the first IRS audit scan: 1. Report all Form W-2 and Form 1099 income. 2. File on time. 3. Attach all required supporting schedules and forms to your return. 4. Don't round off figures to the nearest $50 or $100. If you cannot pay the full amount of the taxes you owe by the April 15 deadline, you should still pay as much as you can by that date, to reduce penalties and interest. A sure way to get your tax return pulled for special scrutiny and special handling is to try to claim non-deductible expenses.
