This page breaks down every cost of forming and maintaining a Connecticut LLC in 2026: the one-time state filing fee, the mandatory annual costs, optional and situation-specific fees, and the true three-year total under each formation option. Every figure is drawn from the Connecticut Secretary of the State and cross-checked against our Connecticut LLC formation guide.
The number most people search for is the formation fee: $120. What this page adds is the complete picture: the ongoing state minimum ($80 per year, which is the $80 annual report), when each item is due, what happens if you miss a deadline, and how total costs compare across formation options over three years.

True 3-Year Total Cost Comparison
The formation fee is paid once. What actually determines your LLC's affordability is the total cost over the years you operate it. Here is the 3-year total under each formation option .
| Scenario | Year 1 | Year 2 | Year 3 | 3-Year Total |
|---|---|---|---|---|
| Northwest Registered Agent | $159 ($120 state + $39 service, RA free) | $205 ($80 state min + $125 RA) | $205 | $569 |
| ZenBusiness (Starter) | $219 ($120 state + $0 service + $99 RA) | $279 ($80 state min + $199 RA) | $279 | $777 |
| DIY, self as registered agent | $120 (filing) | $80 (state minimum) | $80 | $280 |
Finding: Over three years, the difference between DIY (self as agent) and Northwest Registered Agent is $289. That covers registered agent service, keeping your home address off the public record, and compliance reminders so you never miss a filing deadline. For most owners who do not want their home address public, that is a worthwhile trade.
Optional and Situation-Specific Costs
These costs apply only in specific situations. Exact amounts vary; verify current fees with the Connecticut Secretary of the State before filing.
| Cost Item | Typical Amount | When You'd Pay This |
|---|---|---|
| Certified copy of formation documents | $10 to $50 | Some banks and contracts require one |
| Certificate of Good Standing | $10 to $50 | Required for foreign registration or financing in other states |
| Registered agent change | $0 to $25 | When switching registered agents |
| Amendment to formation documents | $25 to $100 | Changing LLC name, address, or other formation details |
| DBA / trade name registration | $10 to $50 | Operating under a name different from your LLC name |
| Expedited processing | Varies by state | When you need faster approval than standard processing |
| Dissolution filing | $0 to $100 | When formally closing the LLC |
| Local business license | $50 to $500/year | Varies by city/county; many localities require one |
Connecticut LLC Cost vs. Other States
Here is how Connecticut compares with several commonly referenced states, using the same 3-year state-minimum methodology (filing fee plus two years of the ongoing state minimum):
| State | Formation Fee | Annual State Minimum | Income Tax | 3-Year State Minimum |
|---|---|---|---|---|
| Connecticut | $120 | $80 | Yes | $280 |
| Wyoming | $100 | $60 | None | $220 |
| Texas | $300 | $0 | None | $300 |
| California | $70 | $810 | None personal / $800 franchise | $1,690 |
| New York | $205 | $29.50 | Up to 10.9% | $264 + publication |
| Delaware | $110 | $300 | None (out-of-state) | $710 |
Finding: Connecticut is on the higher side for ongoing state costs. Weigh that against forming in your actual home state, which is almost always the right choice for a business that operates there.

When a Connecticut LLC Is Not Worth the Cost
An LLC is a great fit for many businesses, but there are situations where the cost outweighs the benefit:
- Pre-revenue or very low-revenue side project: If your business earns little, the annual state costs and any registered agent fee are pure overhead. Operating as a sole proprietor is free until the business is generating real income.
- You plan to keep the LLC dormant: A Connecticut LLC with no activity still owes its ongoing state costs until it is formally dissolved. Dormant LLCs accumulate fees and risk administrative dissolution if a filing lapses.
- You are not actually in Connecticut: Forming here when your business operates elsewhere adds compliance costs and often a second registered agent fee with no benefit. Form in the state where you actually do business.
