Now Government wants to eliminate LIFO. LIFO stands for Last In, First Out. It is an inventory costing methodology. The last in, first out, or LIFO method, selects the most recent purchases whose quantities add up to the total number of items sold during the year. The last in, or most recent purchases, are the first charged out to expense. The primary theory of the LIFO method is that products sold have to be replaced to continue in business and that the most recent (i.e., the last in) costs are the closest to the costs of replacing the products sold. From a tax standpoint, LIFO minimizes tax consequences by using the highest cost of inventory which reduces reported profit.
