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.
  • A Sales and Use Tax Permit is required for applicable taxable goods or taxable services; review DRS classifications, nexus and any exemptions.
  • The general statewide sales and use tax rate is 6.35%; special rates and exemptions apply to some goods and services.
  • 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.
  • Use the applicable DRS rate for the specific taxable good or service; 6.35% is the general rate, with special-rate and exemption exceptions.
  • 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.
