IRS audit penalties are the worst. It is in your best interest to avoid these at all cost. There are a few things that can be done in order to avoid audits. First and foremost, be honest. Make sure you tell the truth, the whole truth, and nothing but the truth to the IRS. If you are lying, the IRS will most likely catch you and I can guarantee you it will not be pleasant. Also you want to make sure you use a tax software program or tax professional to file. This is the easiest way to avoid errors and make sure all calculations are correct. A tax professional will more than likely use a tax software program and by using the program it will make sure that your return is complete before you file. Don’t use round numbers because it is not common to have an investment return of $1,000. Using round numbers is a fast way to get your return alerted for an audit.
