Do non-residents pay more in Connecticut?
The state fees above are the same for everyone - Connecticut does not charge non-residents more to form or maintain an LLC. What changes is the surrounding process and your tax obligations, not the price.
- A Connecticut registered agent is mandatory - you cannot list your own foreign address.
- Get your EIN with Form SS-4 by fax or phone (the instant online tool needs an SSN or ITIN).
- A foreign-owned single-member LLC must file Form 5472 every year - a $25,000 penalty if missed.
- You may owe no US income tax on remote work, but still have US reporting and home-country tax.
- US banking is harder and depends on your residence country - check eligibility before you form.
- You can act as your own registered agent with a Connecticut street address.
- You can get an EIN online instantly with your SSN.
- Form 5472 generally does not apply; you report on your personal return.
- An S-corp election can cut self-employment tax once profit is high enough.
- Forming outside your home state can create a second registration and fee set.

Does Connecticut fit your situation?
Connecticut puts ownership on the public record, so it is not the choice if you need anonymity. It levies a state income tax. Straightforward, mid-cost.
If you do not live or operate in Connecticut, remember that forming here while working elsewhere can create a second state registration (foreign qualification) and a second set of fees. For most non-residents the decision comes down to banking acceptance and total cost - see the best-state comparison.
