State fees summed, years 1 to 3$280Sum of the lines above
Three years of state charges come to the filing fee, the reports owed in years two and three, and a yearly minimum tax where the state levies one. Costs without a fixed amount, newspaper publication for example, are mentioned in the text and excluded from the sum.

What settled it

Duties inside the charge put Mainstay Filing first. That measure is 31% of the order, and charges over three years, charge at renewal, point of equal cost and fee disclosure make up the rest.

The home state counts too; a single account for both scored highest.

The Connecticut foreign LLC registration fee and rules, in the state's own words

If registration is skipped: back fees covering the unregistered stretch.

Filing it yourself
