Connecticut taxes through the Connecticut Department of Revenue Services at a 6.35% statewide base rate, with local rates stacking on top and economic nexus for remote sellers at $100,000 in sales AND 200 transactions. Filing runs monthly, quarterly, or annually by liability. For real estate investors & developers, that combination is what decides how much of your month-end is bookkeeping and how much is compliance.
Employer registration runs through the Connecticut Department of Labor, and the entity is registered with the Connecticut Secretary of the State. One of the few states requiring BOTH thresholds to be met, not either — so high-value, low-volume sellers often are not required to register.

Entity-level obligations in Connecticut
Beyond sales tax, Connecticut entities have their own obligations — registration with the Connecticut Secretary of the State, and whatever annual entity-level tax or report the state imposes. One of the few states requiring BOTH thresholds to be met, not either — so high-value, low-volume sellers often are not required to register. These are recorded as they accrue rather than discovered at year end.
Transfer costs and basis in Connecticut
Connecticut levies a real estate transfer or deed tax at closing, on top of recording fees and title charges. Each of those gets a different treatment — some capitalize into basis, some are deductible now — and drawing that line inconsistently across years is the single most common problem we find in investor books. Getting it right at closing is far cheaper than reconstructing it later.
Connecticut rates and sourcing
The Connecticut statewide base rate is 6.35%. Local rates stack on top and are generally sourced to the delivery address, so the effective rate varies within the state. Getting sourcing right is what keeps the liability account matching what you actually collected.
Registering to do business in Connecticut
Registering to do business in Connecticut runs through the Connecticut Secretary of the State, with tax accounts through the Connecticut Department of Revenue Services and employer accounts through the Connecticut Department of Labor. Connecticut treats these as wholly independent, so being in good standing with one says nothing about the others — and the sales tax account is the one that accrues a real balance while you are not looking.
