And many people get around paying any taxes. People think the IRS can see everything and has access to everything and that is not true at all. Depending on the amount involved determines the extent to which they allocate resources to your case. Your bank account records have to come from you or court ordered. You can, by several ways, eat up too much time for an agent to continue working on your case. The IRS has budget constraints, over-worked agents and managers with time limits. Tax payers make many of the same common mistakes. Don't claim too much, leave some crumbs for use later. Don't try to write off the space in your home, office, garage or yard space. These allowances usually raise flags automatically. Trade mags, clothes, charity, can wait. If you regain 10% of the write-offs in audit your penalties must be reset at zero and the audit is closed. The IRS has 30 days to notify you they want to continue the case.
