FAQ
Do I need a CONCORD account?
Yes — creating an account is required for online filing. It also makes future filings (Annual Reports) easier.
Is the old portal.ct.gov/sots still used?
The SOTS (Secretary of the State) website provides general information, but CONCORD (business.ct.gov) is the filing portal. Use business.ct.gov for actual filings.
