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. Because Connecticut runs an annual bracket, low-volume veterinary practices can go twelve months between returns — which is exactly how long a liability account can drift before anyone looks at it.
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.

Service, pharmacy, and retail in Connecticut
A veterinary practice in Connecticut sells three things the Connecticut Department of Revenue Services treats differently: professional services, dispensed medication, and retail product such as food, supplements, and supplies. Retail is squarely taxable at 6.35% plus local; professional services generally are not; medication sits between them and depends on how it is dispensed. 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. A practice running everything through one revenue account cannot produce a defensible return, and the fix is at the point-of-sale level — the categories have to exist in the system that rings up the sale, not be reconstructed monthly from a spreadsheet.
Dispensed medication in Connecticut
Prescription medication is treated more favourably than general merchandise in most sales tax states, but the boundaries for veterinary use are narrower than people assume — a drug dispensed under prescription and the same drug sold over the counter can carry different answers, and prescription diets and supplements frequently sit on the taxable side of the line. Connecticut sets its own scope through the Connecticut Department of Revenue Services. The bookkeeping consequence is that drug inventory needs categorising by how it is sold rather than by what it is, which is also what makes expiry and controlled-substance tracking workable.
Payroll and employer registration in Connecticut
Employer registration in Connecticut runs through the Connecticut Department of Labor, a different agency from the Connecticut Department of Revenue Services that handles your sales tax — a separate account number, a separate login, and separate deadlines. Standing with one says nothing about standing with the other, and for veterinary practices the first sign of a gap is usually a notice rather than a reminder. Your unemployment insurance rate is set by the Connecticut Department of Labor from your own claims history, which means it is a cost you can actually influence — and one that quietly changes each year while the payroll journal entry stays the way somebody set it up.
Connecticut rates and sourcing
The Connecticut statewide base rate is 6.35%. That sits mid-table nationally, with local rates layered on top and sourced to the delivery address rather than to your own location. Sourcing is where this is won or lost, and with economic nexus set at $100,000 in sales and 200 transactions, it becomes your problem the moment that threshold is crossed.
