There is no legal right to have a valid tax bill reduced by the IRS -- it is entirely a matter of government discretion. But if you qualify for something known as an offer in compromise, you may be able to wipe your tax slate clean at an enormous discount.
In an audit, you must convince the IRS that you reported all of your income and were entitled to any credits, deductions, and exemptions that are questioned. Postponing the audit usually works to your advantage. Request more time whenever you need it to get your records in order, or for any other reason.
Questions I am being audited and the deadline for filing this year's return is fast approaching. Should I file? I am being audited and I haven't heard from the auditor for months. What can I do to get the audit over with? Do I have to let the IRS into my home? The auditor is impossible to get along with.
