Connecticut LLC Business Licenses — Step 7 of 8

Connecticut has no general state business license — but if you sell taxable goods, you'll need a Sales and Use Tax Permit. Remote sellers should pay close attention to Connecticut's unusual nexus rule, which requires clearing two thresholds, not just one.

Quick Answer

Connecticut does not require a general state business license. If you sell taxable goods, you'll need a Sales and Use Tax Permit from the Department of Revenue Services — a one-time $100 fee, renewed every two years. Remote sellers trigger economic nexus only when they exceed both $100,000 in sales AND 200 transactions (measured over the 12 months ending September 30) — one of the few states requiring both thresholds together. Certain professions also require state board licensing.

Connecticut's Licensing Landscape

Connecticut is light-touch at the state level — there's no blanket "state business license" every LLC must get. What actually applies depends entirely on what you sell and how:

  • No general state business license — unlike many states, Connecticut doesn't require every LLC to hold a basic operating license.
  • Sales and Use Tax Permit required if you sell taxable goods — issued by the Department of Revenue Services, this is the closest thing to a universal requirement for product-based businesses.
  • Statewide sales tax rate — 6.35% everywhere, with no local or home-rule city layer to navigate, unlike some neighboring states.
  • Professional and occupational licenses — certain regulated fields (contractors, healthcare, cosmetology, real estate, and more) need licensing through the relevant Connecticut state agency, independent of your LLC formation.

Getting Your Sales and Use Tax Permit

  • Register through myconneCT — the Department of Revenue Services' portal for tax registration, filing, and payments (Form REG-1).
  • $100 non-refundable registration fee — a temporary permit is available to print immediately after applying; the permit renews every two years.
  • Statewide rate is 6.35% — the same everywhere in Connecticut, with no local variation to track (unlike states with home-rule cities).
  • Remote sellers must clear BOTH thresholds — $100,000 in gross Connecticut sales AND 200 separate transactions, measured over the 12-month period ending September 30. Meeting only one threshold does not trigger nexus.
  • Marketplace sales still count toward your own threshold calculation in Connecticut, even when the marketplace (Amazon, Etsy, etc.) is separately collecting and remitting tax on your behalf.

Connecticut's "AND" threshold is unusually strictMost states use an "either/or" nexus standard — hit one threshold and you're registered. Connecticut requires both: $100,000 in sales and 200 separate transactions. A business doing $250,000 in Connecticut sales through just 80 large orders technically hasn't triggered economic nexus, while a business doing $60,000 through 220 small orders also hasn't. Don't assume crossing one number means you're required to register — check both, and track the 12-month window that ends September 30, not the calendar year.

Ahmad Adil's Take: Connecticut's overall licensing burden is genuinely light — no state business license, uniform sales tax statewide, and a straightforward two-year permit renewal cycle. The real thing to watch is the "AND" nexus rule if you sell remotely; it's easy to misread as an "or" and either over-register when you don't need to, or under-register because you crossed one number but not the other. Track both figures over the September-ending 12-month window, not the calendar year.

Frequently Asked Questions

Connecticut Business Licenses — FAQ

Does Connecticut require a general business license?
No. Connecticut does not require a blanket state business license. Licensing requirements depend on what you sell and your profession.
What is Connecticut's economic nexus threshold for remote sellers?

How much is Connecticut's Sales and Use Tax Permit?
A $100 non-refundable registration fee. Unlike some states, there's no annual renewal fee — the permit itself renews every two years.
What is Connecticut's state sales tax rate?
A flat 6.35%, applied uniformly statewide — Connecticut has no local sales tax layer or home-rule cities to track separately.
