TKC Systems Laboratory is the site where innovations take place, with approximately 450 engineers hard at work. The laboratory takes on challenges of developing new systems that help achieve "the complete performance of the services by certified public tax accountants" and "the support for the survival and development of SMEs", based on decisions by the System Development Committee of TKCNF. It is an absolute requirement that systems are developed in full compliance with laws and regulations. The challenge also includes realizing continuous profits in the clients' financial statements through ensuring that their managers have thorough performance management, backed by accurate accounting information. Furthermore, the Center aims to provide them with valuable support for the establishment and implementation of feasible management plans, as well as to leverage the latest technologies of ICT.

TKC Internet Service Center (TISC) is the site from which our "safe, secure, and convenient" cloud services are provided, combining various application software and outsourcing services, as well as online real time processing services for the data transmitted from such places as tax consulting firms.

TKC Local Data Processing Centers is dedicated to information processing functions that "receive, in a form for printing, the data received by TISC from tax consulting firms which has been processed on a real-time basis, print them in a business form, and deliver the forms by the morning of the following day." The center has ultra-high speed printers with an aggregated printing capacity of about 700 thousand lines per minute with nine printing centers. It has also a mechanism where, if one of its centers is prevented from processing data due to a disaster, accident, or power failure, other consolidated centers can act as alternates in collaboration with TISC.

The Local Governments Business Division strives to equip local municipalities with the latest ICT, in line with our second business objective, "management of data processing service bureaus for consultants to improve the administrative efficiency of local governments." Today, the environment surrounding local governments is undergoing drastic changes, such as severe financial conditions, a depopulating society drawing near, and a rapidly aging society coupled with a declining birthrate. We believe that our TKC Government Cloud Service is one of the solutions for these challenges. The TKC systems support improvements in operation processes and help achieve "higher levels of service" and "more simplified and efficient administrative work" in addition to the improvements.
