Filing Requirements 8. Does the CIT follow the federal check-the-box regulations?
Yes. A person that is required or has elected to file as a C corporation as defined under sections 1361(a)(2) and 7701(a)(3) of the IRC is by definition a corporation under the CIT. This statutory definition effectively adopts the federal "check-the-box" regulations for CIT purposes.
C corporations, insurance companies, financial institutions, and unitary business groups are subject to tax under the CIT.
