You can use Form 4506 to order a copy of your tax return. Generally, there is a $39.00 fee (subject to change) for requesting each copy of a tax return. If your main home, principal place of business, or tax records are located in a Presidentially declared disaster area, the fee will be waived if the assigned disaster designation (for example, "Kansas Storms") is written in red across the top of the form when filed.taxmap/pubs/p4492a-006.htm#en_us_publink100016370
