Personal Income Tax
Income tax in Connecticut is affected by exemptions and credits for which you might be eligible, your income level, and your filing status. Taxes are calculated according to a graduated scale but do not exceed 5 percent. Generally, adjustments to gross income allowed by the federal government also apply to the state. The self-employed or those who earn income from non-taxed sources may also need to provide estimated payments throughout the tax year.

Part-year residents, non-residents, trusts and estates will also be taxed on the portion of their income that is attributable to sources within Connecticut. By the same token, credit is available to Connecticut residents and part-year residents for income taxes paid to other states. For answers to questions or further assistance with your specific tax situation, contact the State Department of Revenue Services or stop by one of the regional offices.

Sales/Use Tax
The general sales tax levied on nonexempt goods and services in Connecticut is 6 percent, although some items and services may be taxed at lower rates. Among the sales tax exemptions are food, prescription drugs, utilities, and a number of other categories. In general, goods or services are subject to the Connecticut 6 percent use tax if they were purchased outside the state but would have been taxed had the purchased occurred in the state such as Internet or catalog orders. Full or partial credit is given for sales tax properly paid to another state. For example, an automobile purchased in a state with a 5 percent sales tax would require an additional 1 percent paid to Connecticut at the time of registration. Use tax must be reported and paid by April 15, for all purchases subject to Connecticut use tax made during the previous calendar year.

Personal Property Taxes
Personal property taxes are levied by the community on automobiles, motorcycles, and mobile homes at 70 percent of the present true and actual value times the mil rate of the community. Inventories are exempt from property taxes. Contact your local tax official for details.

Real Property Tax
Real estate taxes are levied by individual communities and reassessed every four years. They are calculated on 70 percent of the fair market value times the mil rate of the community. Many factors can affect the valuation of a specific property, from the location of the property to special taxes in your municipality. The most detailed and accurate information on property taxes will always be available from your local tax assessor. Assessing and recording is handled at the city and town level. For more information, contact your local tax official.
