Once the IRS is certain that they want to do further examination into your tax returns, they then
decide if they want to do the audit by mail correspondence or in person through an interview. For the
mail correspondence audit, they will send you a letter asking for more clarifying information about
your taxes. If this happens, you can either respond by mail or opt for the personal interview. The
in-person audit however, is much more time consuming. This type of audit could take place in the
nearest IRS office branch or in your business office or home and you have a say as to what time you
are able to meet with them.
