In line with the efforts on harmonisation with the European Union and international tax treaty applications, the Law Amending Certain Laws (Law No. 5838) was enacted on 18 February 2009. This law has introduced the concept of "tax credit" as a form of investment incentive. According to this amendment, revenue derived from the investments indicated within the Law, linked with incentive certificates (to be obtained from the Undersecretariat of the Treasury), will now be subject to the reduced corporate tax starting from the fiscal year of initial investment until the investment amount reaches the legally prescribed investment contribution amount on the part of the Treasury.

This law has also introduced various corporate tax incentives for the purpose of business relocations with respect to textile, ready-to-wear/confection, garments, leather and leather products sectors while amending the scope of the related incentive provisions in the Corporate Tax Law.
