The provisions of the Tax Procedure Law (TPL), Turkish Accounting Standard 2 (TAS 2), and Financial Reporting Standard for Large and Medium Sized Enterprises (LME FRS) regarding inventories have been compared in the study. In addition to being compatible with the general outlines of the regulations, it has been observed that there were some fundamental differences between them. In the study, these differences were discussed under the headings of borrowing costs and exchange differences in inventories, including maturity differences in inventories, valuation of inventories, and cost methods according to scope. The aim of the study is to determine the effects of these differences on the financial statement items of a production company. For this purpose, the method chosen in the study is the case study method, and besides this method, observation and interview methods have also been included. As a result of the decomposition of borrowing costs and exchange differences in inventories, the cost of inventories has decreased, and the inventories have less value in the balance sheet as well. In addition, late payment differences in the cost of inventories were separated, and since these differences were deducted from the cost of goods sold, the gross sales profit in the income statement increased. Since late payment differences were deducted from inventories as in foreign exchange differences, the value of the inventories group in the balance sheet has decreased. Impairments in inventories were followed in the Inventory Impairment Provision Expenses account. As a consequence of the recording, the decrease in value increased the cost of sales items in the income statement and accordingly decreased the gross sales profit. In spite of this, the same depreciation led to a decrease in the inventory items located on the balance sheet and thus in the total assets. While calculating the costs of sales of the enterprise, which is the subject of the application, it has been observed that the gross profit increased as a result of applying the normal cost method. In line with this information; it has been concluded that the differences between the TPL and the standards affect some account items in the financial statements of the enterprise.
