Common Questions About IRS Tax Defense

What are the most common reasons for an IRS tax audit?

The IRS typically audits returns that show unusually high deductions, complex transactions such as those involving foreign accounts or entities, and discrepancies between reported income and third-party information reports.

Can I negotiate with the IRS to reduce my tax debt?

Yes, through an Offer in Compromise program, you may be able to settle your tax debts for less than the full amount if certain criteria are met, such as proving payment in full would cause financial hardship.
