If you do not have complete records to prove an element of an expense, then you must prove the element with:
*Your own written or oral statement, containing specific information about the element, and
*Other supporting evidence that is sufficient to establish the element.

Destroyed records. If you cannot produce a receipt because of reasons beyond your control, you can prove a deduction by reconstructing your records or expenses. Reasons beyond your control include fire, flood, and other casualty. Go through your bank statements, canceled checks, credit card statements and other records to collect as much information as you can.
