Strike-off company monitoring for GST revenue protection through regular review of MCA lists and related categories. CBIC GST-investigation formations are directed to regularly monitor Ministry of Corporate Affairs lists relating to companies under strike-off proceedings and other associated categories, including STK-5, STK-6 and STK-7, so that any necessary protective action can be initiated to secure the interest of revenue. The guidance emphasises a proactive review of the MCA website because the available lists are RoC-wise but may still affect GST registrations or business footprints across the country.
