Texas residents may be concerned about getting selected for an audit by the Internal Revenue Service. However, having knowledge about what the process can entail and what a person's rights are in the process can go a long way toward addressing many concerns. First of all, its important to know that an audit does not always mean that there is a problem. It is possible someone is selected for an audit based on a statistical formula. Tax returns are compared against similar tax returns with the help of a computer program. Tax returns can also be selected for an audit if they involve issues with other taxpayers whose audits were selected for audit.
