There are three types of audits: a correspondence audit, an office audit and a field audit. A correspondence audit is simply a letter from the IRS indicating that they are questioning something on a tax return you filed and are proposing a change to your tax return. An office audit is completed by an IRS Revenue Agent at the Revenue Agent’s office. A field audit is conducted at your home, place of business or accountant’s office. Office and field audits are generally more detailed audits. The most common audits are correspondence and office audits. A correspondence audit can be something simple like an addition error on your tax return or something more complex like Earned Income Credit. It is important to get good representation to help with office audits, field audits and many correspondence audits. Call IRS Tax Fighters at 1-888-959-2671 for help.
