States generally employ one of the two following methods in calculating corporate taxable income:
1. Moving (or rolling) conformity—the determination of state-level taxable income begins with federal taxable income as calculated for the current year under the current applicable provisions of the Internal Revenue Code.
2. Static conformity—the determination of state-level taxable income begins with federal taxable income as it would have been calculated under the Internal Revenue Code as of a specified date.
