General Instructions 49C
Complete this form if an investment tax credit (ITC) carryover is included in the current year's available credit. Once the Form 49C is completed, the carryover will be carried to Form 49.
Carryover Period
ITC earned in tax years beginning on or after January 1, 2000, can be carried forward up to 14 succeeding tax years. Credit earned in tax years beginning before 2000 can also be carried forward up to 14 tax years if the 7-year carryover allowed for these years didn't expire before the first tax year beginning in 2000. For purposes of the carryover period, a short tax year counts as one tax year.
