Working with financial advisors or public accountants in economical matters in our country dates back to the first periods of the Republic. Since 1950, contemporary taxation system, similar to those in western countries, has been put into effect in the Turkish Tax System and the need for public accountants has increased in paralel with that system. The increase in the relative importance and presence of the private sector in the Turkish economy has expanded the actual working areas as well as the need for public accountants.The Law No. 3568 that came into force in 1989 is considered a milestone for our occupation. In the following years, public accountants were encharged with numerous responsibilities and duties. The tax inspection authority of the public is partially privatised. In particular, with the regulation of full certification authority in 1995 and its attornment to Sworn-in Certified Public Accountants, the responsibility of investigating, confirming and ensuring the accuracy of the tax to be paid has been handed over to the members of the profession.Sworn-in Certified Public Accounting is a career profession. Working with a Sworn-in Certified Public Accountant, getting consultancy service from them, working within the scope of full certification is a way of showing seriousness. In other words, companies that take their job seriously, do not want to be in a difficult situation in the face of public regulations, and want to minimize their mistakes generally prefer to work with a Certified Public Accountant.
