State tax filing
@paylesstax Do Caterpillar and Abbvie still qualify for River Edge Development Zone Dividend subtractions on Illinois state income tax form 1299-C in 2022? I used Peoria as the zone for Caterpillar but wasn't aware Abbvie qualified. What zone are they in? How many years can I go back and submit an amended return for Illinois?
