Audits from the IRS are no picnic. The Internal Revenue Service has a job to do, and that often involves targeting people they think are gaming the system for a more intensive inspection. The IRS can ask for clarification, adjust your tax filing for you (and allow you to either accept the changes or show proof that you had the correct figures to begin with), or go all in with an audit of your finances. They are rare, but the IRS is more likely to audit taxpayers whose returns have certain red flags.
