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 farms and agriculture 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.

Agricultural exemptions in Connecticut
Connecticut exempts a defined set of agricultural purchases from sales tax — typically inputs consumed in production such as seed, feed, and fertiliser, and often machinery used directly in farming — with the exemption claimed by certificate at the point of purchase through rules the Connecticut Department of Revenue Services sets. 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. The boundary is where it gets expensive: a vehicle or a piece of equipment used partly for farming and partly for something else, or a purchase made without presenting the certificate, is taxable, and recovering it afterwards means a refund claim. Filing the certificates and coding exempt purchases as exempt is what makes the position defensible.
Farm payroll in Connecticut
Farm payroll in Connecticut runs through the Connecticut Department of Labor like any other employer registration, but agricultural employment carries its own rules and they are the ones that cause problems: seasonal and migrant labour with concentrated hiring, overtime and wage rules that treat agriculture differently from other industries in some states, and where an operation uses a temporary agricultural visa program, an entirely separate set of wage and housing obligations. Records have to support all of it and have to be built as the season runs — a harvest crew is not something anyone reconstructs in March. Crew leaders and custom operators paid as contractors need their information returns handled at the time, and where a custom operator's charge includes materials rather than labour alone, the Connecticut Department of Revenue Services may treat that differently from a pure service — worth settling before the invoice rather than after.
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.
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.
