Compare LLC Costs: Connecticut vs Delaware

Filing Fees & Formation Costs

Connecticut charges $120 to form an LLC, while Delaware charges $110. Delaware is $10 cheaper upfront. The cost that usually gets overlooked: if you form in Delaware but operate in Connecticut, you must also register as a foreign LLC in Connecticut (a $120 filing) and maintain a registered agent in Delaware (typically around $150 per year). That puts the realistic first-year cost of the Delaware route at roughly $380, versus $120 for simply forming in Connecticut. Speed isn't a basis for choosing between them: neither Connecticut nor Delaware publishes a standard processing time, so any figure comparing the two is guesswork.

Taxes: Connecticut vs Delaware

Both Connecticut and Delaware levy a personal income tax on pass-through business income, and your LLC's profits will be taxed where you live and operate. Forming in Delaware doesn't change what a Connecticut-based owner pays. Delaware LLCs owe a flat $400 annual LLC tax (no report required).

Privacy & Asset Protection

Delaware allows anonymous LLC formation. Member and manager names don't appear on routine public filings. Delaware's Certificate of Formation requires no member or manager names, and LLCs file no annual report, so ownership never appears on a public filing. Connecticut doesn't offer that same privacy. Connecticut's annual report discloses the LLC's members or managers, a public filing. Both states provide charging-order protection for LLC members, and for most small businesses the practical difference in asset protection between the two is minimal. One important caveat: if you register your Delaware LLC as a foreign LLC in Connecticut, that Connecticut registration is itself a public record, which can undercut much of the privacy benefit for a business that operates in Connecticut.

Annual Maintenance Costs

Connecticut LLCs file an annual report ($80, due March 31), and Delaware LLCs file no annual report at all. If you form in Delaware while operating in Connecticut, you maintain filings in both states, Delaware asks for no report, but Connecticut still wants its equivalent for your foreign registration, and pay a Delaware registered agent roughly $150 per year. Counting report fees, the agent and any entity-level tax, that brings the Delaware route to roughly $630 a year, versus about $80 to keep a domestic Connecticut LLC in good standing. The tax inside those totals: Delaware LLCs owe a flat $400 annual LLC tax (no report required).

When Delaware Actually Makes Sense

Forming in Delaware makes sense in a few specific situations: you need anonymous ownership. Connecticut puts owner or manager information on public filings and Delaware doesn't (usually via a holding company, since operating in Connecticut still requires a public foreign registration there), you're raising venture capital or institutional investment. Many investors specifically prefer or require Delaware entities, your business genuinely operates in Delaware, with a real office, employees, or property there, or you're relocating to Delaware in the near future. For a typical small business based in Connecticut, none of these usually apply. Registering a Delaware LLC to do business back home means $120 in Connecticut foreign-registration fees, on top of Delaware's $110 formation fee, while Connecticut's own annual report runs $80 a year and is due March 31. When in doubt, form where you actually do business.
