Best 2026 Connecticut LLC Formation Services
Last Updated: March 2026
Interested in starting a business in Connecticut? This guide covers everything you need to know about Connecticut LLC formation services, including the state's 2021 repeal of its biennial business entity tax and its streamlined annual report process.
This guide covers:
- Connecticut's specific requirements, including a $120 filing fee, $20 annual report, and no franchise tax (business entity tax repealed)
- When national providers make sense versus local Connecticut registered agents
- Direct comparisons of LLC Attorney, LegalZoom, Northwest Registered Agent, ZenBusiness, and Bizee
- Which option fits your business based on your budget and growth plans
Whether you're starting a financial services firm, a professional services practice, a healthcare company, or a tech startup in Hartford, Stamford, or New Haven, you'll know exactly what you're getting into with a Connecticut LLC.
Understanding Connecticut's Unique LLC Requirements
Connecticut charges $120 to file Articles of Organization with the Connecticut Secretary of State. Processing typically takes 3–5 business days. Connecticut made a significant change in 2021 — it repealed its $250 biennial business entity tax, substantially reducing the ongoing cost of maintaining a Connecticut LLC.
Business entity tax repealed. Connecticut previously required LLCs to pay a $250 biennial business entity tax. This tax was repealed effective in 2021, eliminating a significant ongoing cost for Connecticut LLCs. There is now no franchise tax or equivalent for Connecticut LLCs — only the $20 annual report fee applies.
$20 annual report. Connecticut requires an annual report with a $20 fee, due each year. At $20, this is one of the lower annual report fees among northeastern states. Your registered agent must have a physical Connecticut street address.
Connecticut does not require a written operating agreement by statute, but it is strongly recommended. Without one, Connecticut's default LLC statutes govern your business. LLC Attorney can help you draft an operating agreement that protects you, your partners, and your personal assets.
No franchise tax. Since the repeal of the business entity tax, Connecticut LLCs face no franchise tax. Profits pass through to members and are taxed on personal federal and Connecticut state returns only. Connecticut's income tax rates range from 3% to 6.99%.
Connecticut LLC Formation: The Basics
Before comparing services, here's what you're actually filing.
What you file: Articles of Organization with the Connecticut Secretary of State. You must designate a registered agent with a physical Connecticut street address.
State filing fee: $120 (one-time formation fee).
Standard processing: 3–5 business days. Many formation services offer expedited submission.
Using a professional registered agent keeps your home address off public records and ensures you receive legal documents and state notices properly.
National vs Local Business Formation Providers
National Providers
Companies like LLC Attorney, LegalZoom, and Northwest Registered Agent operate nationwide. They're your best bet if you're planning to grow beyond Connecticut, need extra support services, or think you might register in other states down the road.
National providers bundle in services beyond registered agent services; for instance, compliance calendars, annual report filing, tax election changes, document storage, and expert support. If you expand to multiple states, you can manage everything from one dashboard with one provider. Pricing runs from $125 to $249 per year. Northwest charges $125/year. LegalZoom is at the higher end with $249/year. LLC Attorney structures things differently by bundling registered agent service into their compliance plans starting at $14.99/month. That Standard plan includes mail scanning and access to professionally trained Business Success Advisors.
Local CT Providers
Local providers focus exclusively on in-state services. They primarily serve Connecticut-only businesses seeking standalone registered agent services. While local providers are typically lower cost for registered agent services alone, they offer limited support beyond basic compliance services and cannot assist with multi-state operations.
Making Your Decision
Choose a local provider if:
- Your business is Connecticut-only and will never expand to other states
- Cost is the primary factor and you want the lowest annual fee
- You don't need bundled services, just basic registered agent functionality
Choose a national provider if:
- You want bundled services like mail forwarding and document storage managed in one place
- You need scalability: one provider relationship and one dashboard for multiple or evolving businesses
- You prefer established support infrastructure with dedicated account representatives
- You value having legal or professional guidance available (business success advisors or access to attorneys)
- You anticipate business growth beyond Connecticut, adding additional businesses, or may want to evolve your business into a more complex entity (such as transitioning from an LLC to a corporation)
Consider LLC Attorney specifically if you want professionally guided services with room to grow. View LLC Attorney pricing or see how Connecticut LLC formation with first year registered agent service works.
Base Service Fee Comparison
Here's what each provider charges before you add anything else:
Main Pricing Comparison
| Provider | Starter/Basic Plan | Mid-Tier Plan | Premium Plan |
|---|---|---|---|
| LLC Attorney | $49 + state fee | Professional: $199 + state fee | International+: $399 + state fee |
| ZenBusiness | $0 + state fee | Pro: $199/yr | Premium: ~$349 (renews $399/yr) |
| Bizee | $0 + state fee | Standard: $199 + state fee | Premium: $299 + state fee |
| LegalZoom | $0 + state fee | Pro: $249 + state fee | Premium: $299 + state fee |
| Northwest Registered Agent | $39 + state fee | N/A (Single tier) | N/A |
What These Numbers Actually Mean
Cheapest upfront: ZenBusiness, Bizee, and LegalZoom advertise $0 plans, but these exclude essential services you'll need to pay for separately.
Most transparent: Northwest ($39 + state fee) and LLC Attorney ($49 + state fee) show you the real starting price with clearer included features.
Professional formation: LLC Attorney provides professionally trained Business Success Advisors who can guide you through decisions. LegalZoom offers attorney connections through their premium plans.
24-hour filing included: LLC Attorney includes same-day filing at no extra cost. Most competitors charge between $50 to $170 for expediting, a significant hidden cost when you need quick turnaround.
Hidden reality: Those "free" plans become $200-400+ once you add required services like registered agent, EIN, and operating agreement.

Key Differentiators
LLC Attorney: Offers professionally trained Business Success Advisors, 24-hour filing included in every package, professionally drafted Operating Agreements, flat-fee attorney consultations, and optional subscription tiers for ongoing compliance support. Serves all 50 states with multi-state anonymous filing options. Standard subscription includes CTA compliance assistance and mail scanning.
- 24-hour filing included: LLC Attorney includes same-day filing at no extra charge. When you're racing against a real estate closing deadline or investor timeline, this included service saves you $100+ that competitors charge.
- Professionally drafted documents: LLC Attorney provides professionally drafted Operating Agreements, not just auto-generated templates. This matters for complex ownership structures or asset protection planning.
- Ongoing attorney access: LLC Attorney offers flat-fee consultations available anytime. Virtual Office+ subscription includes free consultation if sued, providing peace of mind that template-only services can't provide.
- Unlimited updates: LLC Attorney's Virtual Office+ subscription provides unlimited OA updates and state filings (pay state fees only), critical for growing businesses that need flexibility without per-transaction fees.
Registered Agent Cost Comparison
Registered agent service is legally required in Connecticut.
Using a registered agent keeps your home address off public records — a requirement under Connecticut business formation laws.
Ongoing Annual Costs
| Provider | First Year RA Cost | Renewal Cost (Annual) | Included in Base? |
|---|---|---|---|
| LLC Attorney | Included in monthly compliance subscription ($14.99/mo on Starter) | Included in monthly compliance subscription ($14.99/mo on Starter) | Via subscription |
| ZenBusiness | $99 (add-on to Starter) | $199/year | Not included Starter or Pro; Premium only |
| Bizee | Free first year | $119/year | Free first year, then paid |
| LegalZoom | $249/year | $249/year | Not included (always paid) |
| Northwest Registered Agent | Free first year (with formation) | $125/year | Free first year |
Cost Reality
LegalZoom has the highest registered agent costs ($249/yr) and never includes a free first year. LLC Attorney bundles registered agent service with compliance subscriptions. Connecticut's $20 annual report and eliminated business entity tax means registered agent fees are now the primary ongoing compliance cost.
Key Differentiators: What Actually Separates These Services
1. Filing Speed & Turnaround Time
Different providers have different standard processing times for LLC formation filings. Some providers include expedited filing in their base packages, while others charge additional fees for faster processing.
| Provider | Standard Timeline | Expedited Options |
|---|---|---|
| LLC Attorney | 24 business hours | Included (no extra charge) |
| ZenBusiness | 7-10 business days | Available for $79+ fee |
| Bizee | 5-10 business days | Available from $50 (dependent on state) |
| LegalZoom | Up to 30 business days (Basic) | $100+ for 1-5 days |
| Northwest | Standard processing | Available for fee |
LLC Attorney: 24-hour filing is included in every package, even the $49 Starter. When competitors charge $79+ for expedited processing, this alone can make LLC Attorney's $49 base price more cost-effective than "free" alternatives. Plus, professionally trained Business Success Advisors review your filing before submission, reducing the risk of costly errors and rejections that delay your formation even further.
2. Legal Expertise & Attorney Access
LLC Attorney:
- Business Success Advisors available for free (professionally trained support), professionals who understand entity formation law and can guide your decisions
- Flat-fee 30-minute attorney consultations available anytime, no surprise hourly billing
- Professionally drafted Operating Agreements — customized for your specific business structure, not generic templates
- Personalized legal guidance for your specific situation, whether you're structuring multi-member ownership or planning for asset protection
- Virtual Office+ includes free attorney consultation if sued, legal support when you need it most
- Attorney-trained advisors guide entity selection, structure, and next steps, helping you avoid costly mistakes before they happen
LegalZoom Premium:
- 30-minute attorney consultations for 30 days in Pro subscription plan (new topics)
- Connects to third-party attorneys (not in-house)
- No attorney-client confidentiality with LegalZoom itself
All Other Providers:
- Customer service cannot provide legal advice, just administrative support
- Automated document generation only
- Must hire separate attorney for legal questions (typically $200-400/hour)
3. Privacy & Confidentiality
When forming an LLC, sometimes it is desirable to form it with private filings or anonymity. Some reasons include: real estate investors who want to prevent tenants or competitors from finding their other property holdings; e-commerce sellers avoiding competitor research by keeping business structure confidential; high-net-worth individuals seeking asset protection through separation of personal identity from business assets; businesses in litigious industries reducing exposure to frivolous lawsuits; public figures and content creators maintaining personal privacy while running businesses.
Strongest privacy:
LLC Attorney: Attorney-trained advisors understand privacy structuring, not just filing forms but strategic planning; multi-state expertise for clients needing privacy across jurisdictions.
Northwest: Strong privacy policy, no data-selling, corporate commitment to client confidentiality.
Caution: ZenBusiness: Data-sharing reported; marketing partnerships. Bizee: Data-sharing and upsells reported. LegalZoom: Large company, unclear data practices.
4. Support Quality & Response
The quality of customer support matters when you're navigating complex business formation decisions.
| Provider | Support Quality | Attorney Access | Customer Reviews |
|---|---|---|---|
| LLC Attorney | Business Success Advisors + attorney access | Yes | 4.3/5 on Trustpilot (December, 2025) |
| LegalZoom | Phone/chat/email 7 days | Premium only (30 days) | 4.6/5 on Trustpilot (December 2025) |
| Northwest | Great phone/email | No | 3.8/5 on Trustpilot (December 2025) |
| ZenBusiness | Chat/email | No | 4.8/5 on Trustpilot (December, 2025) |
| Bizee | Chat/email | No | 4.7/5 on Trustpilot (December, 2025) |
What sets LLC Attorney apart: Business Success Advisors aren't just customer service reps; they're professionally trained professionals who understand business law. They can guide your entity selection decisions, explain ownership structures, and help you determine when you need full attorney consultation. This level of expertise is unavailable from chat-only support teams at other providers.
5. Transparency & Hidden Fees
Most transparent:
LLC Attorney: Clear base pricing with optional add-on subscriptions you can evaluate upfront. Northwest: Clear pricing, no upsells, straightforward service model.
Hidden fees/upsells:
LegalZoom: $249/yr registered agent always costs extra; frequent upsells; Basic plan takes 30 days (forcing expedite fees). ZenBusiness: Dashboard upsell prompts after formation, additional services pushed constantly. Bizee: Many add-on charges, what looks cheap becomes expensive.
6. Ongoing Compliance & Updates
Annual compliance requirements vary by state, but every LLC needs ongoing support to maintain good standing. Compliance memberships provide proactive support for registered agent services and other compliance-related needs.
LLC Attorney:
- Standard subscription ($14.99/mo): Registered agent service, CTA compliance assistance, 5 free mail scans/year
- Professional subscription ($29.99/mo): Standard + unlimited mail scans + unlimited OA updates + legal templates, tools you need as you grow
- Virtual Office+ subscription ($49.99/mo): Professional + custom OA + unlimited Certificates of Good Standing + unlimited state filings + free attorney consultation if sued, comprehensive protection for established businesses
- Business Success Advisors provide ongoing guidance, not just automated reminders, but actual support
LegalZoom: Separate compliance services (extra cost), pay per transaction or service. Others: Automated alerts only, no attorney guidance, you're on your own to figure out requirements.
Why this matters: According to the Small Business Administration, failing to maintain compliance can result in administrative dissolution, loss of liability protection, and penalties. Having professionally trained advisors available gives you confidence you're handling requirements correctly.
Total Cost of Ownership: 3-Year Comparison
Here's what you'll actually pay over three years, including required services. This realistic comparison factors in costs that every LLC needs: formation, registered agent, operating agreement, EIN, and compliance monitoring.
Assumptions: CT LLC, $120 state fee, registered agent required, $20 annual report, no franchise tax, operating agreement recommended, EIN needed
| Provider | Year 1 | Year 2 | Year 3 | 3-Year Total |
|---|---|---|---|---|
| LLC Attorney (Starter + Standard subscription) | $398.88 ($49 + $120 state + $179.88 sub + $20 annual report) | $199.88 ($179.88 sub + $20 annual report) | $199.88 | $798.64 |
| LegalZoom (Basic + required add-ons) | ~$618 ($0 + $249 RA + $120 state + $249 Pro) | $269 ($249 RA + $20 annual report) | $269 | ~$1,156 |
| ZenBusiness (Starter + add-ons) | ~$417 ($0 + $120 state + $99 RA + $99 OA + $99 EIN) | $219 ($199 RA + $20 annual report) | $219 | ~$855 |
| Bizee (Basic + add-ons) | ~$230 ($0 + $120 state + $0 RA + $40 OA + $70 EIN) | $139 ($119 RA + $20 annual report) | $139 | ~$508 |
| Northwest | ~$209 ($39 + $120 state + $0 RA + $50 EIN) | $145 ($125 RA + $20 annual report) | $145 | ~$499 |
Key Insights
- "Free" plans aren't cheaper once you add required services; the advertised $0 becomes $300-700+ in year one alone.
- LegalZoom is most expensive due to high registered agent costs ($249/yr), nearly over $400 more over three years compared to LLC Attorney.
- LLC Attorney provides attorney access at competitive pricing, professional guidance without the premium typical of professionally guided services. You're getting law firm expertise at online service prices.
- Over 100,000 businesses formed, proven track record helping entrepreneurs launch successfully across all 50 states.
