A renewed Digital Signature Certificate is a new certificate, not an extension of the old one \u2014 so every portal that knew your old DSC has to be told about the new one.<\/strong> The person, the PAN and the DIN are unchanged, but the certificate carries a new key and serial number, and each portal checks the certificate it has on record. Skipping this step is the most common reason a filing fails in the week after a renewal, usually with a message that blames something else.<\/p>\n\n\n\n

Do the portals you file on most often first. For a company director that is usually MCA and GST; for a deductor, TRACES before the next quarterly statement.<\/p>\n\n\n\n

Three utilities, not one<\/h2>\n\n\n\n

“emSigner” is used loosely for every signing tool, but the portals use different ones, and they run side by side on the same computer:<\/p>\n\n\n\n
