Annual report cost

Connecticut LLCs file an annual report online each year. The Secretary of the State lists the annual report fee as $80 and the filing window as January 1 through March 31.

The annual report is separate from Connecticut tax filings. It updates the Secretary of the State’s business record.

Sales tax permit cost

If the LLC sells taxable goods or services, it may need a Connecticut sales and use tax permit from the Department of Revenue Services. DRS lists the permit fee as $100.

Connecticut sales tax is state-level. DRS notes there are no additional sales taxes imposed by local jurisdictions in Connecticut.

Common cost mistakes

Treating $120 as the all-in price

$120 is the entity formation filing. It is not a complete operating budget.

Missing the January-March annual report window

The report is due every year even if the LLC had little activity.

Confusing registered agent service with LLC formation

Registered agent service is only the official contact/address role unless the provider also sells formation filing separately.

Forgetting DRS registration

Connecticut tax accounts are separate from Secretary of the State formation.
