Hi @RobertB4444
Later I found a paragraph in page Credit for Taxes Paid to Another State | Virginia Tax (copied below), which fits my situation, does it affect your conclusion that I still have to file Illinois tax return in order to claim Virginia tax credit?
- Pass-through entity composite returns: If you are an owner or shareholder in a pass-through entity (PTE), and you are included in a nonresident composite return filed by the PTE in another state, attach a composite filing statement from the PTE showing your inclusion in the filings as well as your share of the income, tax liability, and taxes paid. Preferred formatting for a composite filing statement.
