The Sales and Use Tax is a state-imposed tax on various transactions, including the sale, rental, or lease of goods, sale of taxable services, and operation of lodging establishments within Connecticut. Individuals and businesses engaging in these activities are required to register with the Department of Revenue Services (DRS) and obtain a Sales and Use Tax Permit. Tax rates vary depending on the type of transaction, with special rates applying to certain sales, such as meals, luxury items, and other specific goods. Businesses are required to electronically file Form OS-114 to report all sales activity, regardless of whether taxes are due.
