**1. Introduction**

Every country initially established its own accounting techniques to report the results of the activities of the enterprises to the relevant interest groups. Due to economic, historical, and traditional differences, there are differences between the accounting techniques. A need to standardize accounting techniques was born both locally and internationally in order to eliminate these differences, which caused negativity about the consistency and comparability of the information in the financial statements. The existence of different accounting systems for different countries can cause various difficulties for international money flow, while a Uniform Accounting System makes it easier for businesses. The existence of a single accounting system to be implemented by all enterprises increases the speed of international transactions, facilitates transparency, and supervision in financial statements and also facilitates transactions.

To eliminate the differences in accounting practices; to perform uniformity in the accounting principles; to ensure that the financial statements are clear,

appropriate, understandable, objective, and comparable; to prevent misappropriation of the individuals and institutions related to enterprises; to prevent wrong decisions; and to create a common language during the production and presentation of financial information, Uniform Accounting System and Uniform Chart of Accounts came into force in Turkey in 1994 and still continue today.

As with financial reports prepared in accordance with the different legal and financial structures of countries, International Accounting Standards (IAS) were made compatible which resulted in an exact translation of the International Accounting Standards (IAS), and International Financial Reporting Standards (IFRS) were entered into force as Turkish Financial Reporting Standards (TFRS) in Turkey. Public Oversight, Accounting and Auditing Standards Authority (POAASA) is authorized for the creation, publishing, and monitoring of changes of the accounting standards that are in compliance with international standards. POAASA aims to ensure the transparency, reliability, comprehensibility, comparability, and consistency of the financial statements of the firms. Currently, there are various accounting practices in Turkey, and the preference of which one to be used depends on being subject to independent audit by the enterprises. Companies whose shares are traded on the stock exchange and that are subject to independent audit apply TFRS, while Large- and Medium-Sized Enterprises which are subject to independent audit but whose shares are not traded on the stock exchange and do not apply TFRS, apply Financial Reporting Standards for Large- and Medium-Sized Enterprises (FRS for LMEs). Enterprises that are not subject to independent audit apply Uniform Accounting System.

Uniform Chart of Accounts is used by all businesses. Despite the application of new accounting standards in Turkey, there are no new regulations regarding the needs of Uniform Chart of Accounts, which are used by the companies that perform accounting and reporting in accordance with these new standards. In Uniform Chart of Accounts, there is a need for a revision of the needs of enterprises.

Banks and insurance companies: private financial institutions: financial leasing, factoring, and financing companies: security mutual funds, brokerage houses, and investment trusts are subject to Banking Regulation and Supervision Agency (BRSA) legislation and have a different chart of accounts, and a revision has been performed for this chart of accounts. The mentioned company activities are accounted in accordance with the declarations of BRSA and TFRS.
