The IRS will sometimes audit your return. It can be because they see something in your return that makes them believe you made a mistake, or it can be because they have other information in your file that disagrees with how you prepared your return, like a missing 1099 or other form. It can even be completely random! IRS audits can be intimidating if you don’t have experience dealing with auditors. It’s hard to know exactly what they’re looking for and saying you might owe. Most often, taxpayers owe much less than the IRS says they do, if anything at all. You should have someone on your side who has experience dealing with the IRS and who knows tax laws inside and out.
