Address and privacy issue
Connecticut LLC filings can ask for member or manager business and residence address information. Review the filing carefully before submission if privacy is important.
A commercial registered agent can help keep a home address out of the registered agent field, but it does not automatically remove every owner or manager address requirement.

- Approve local licenses
- Open a bank account
- Elect S corporation tax status
Common filing mistakes
Filing with a name that has not been checked
Search before paying the filing fee.
Using inconsistent names across records
Use the exact accepted legal name on IRS, bank, DRS, payroll, and license accounts.
Ignoring address visibility
Review registered agent and member/manager address fields before filing.
Waiting on the annual report
