Frequently Asked Questions
How long does a dependent audit take?
It varies. Simple correspondence audits may take a few weeks to a few months. More complex audits can take 6 months to a year or more.
Do I need a tax professional for an audit?
Not always, but it's often helpful, especially for complex situations or if you're uncomfortable dealing with the IRS. A professional can represent you and knows the audit process.
What if I don't have all the documents?
Provide what you have and explain what's missing. The IRS may accept alternative documentation or may disallow the claim if you cannot prove it.
Can I appeal if the IRS disallows my claim?
Yes. You have appeal rights. You can appeal the IRS determination through the appeals process or go to tax court.
What if the audit finds I made an honest mistake?
