In Connecticut the property assessment is equal to 70% of the fair market value of the property as established by the municipal Assessor. The property tax rate is expressed in mills or thousandths of a dollar. A tax rate (mill rate) of 11.74 mills is equivalent to $11.74 of taxes per $1,000 of assessed value.
Each town sets its own mill rate; some municipalities have different mill rates for different districts within that town. Assessment dates for property on the Grand List must be assessed by October 1st of the preceding year. So for property taxes due July 1st, 2014 and January 1, 2015 are determined from assessments computed by the town assessor prior to October 1, 2013 Grand List. Typically the majority of Connecticut towns, real property taxes are payable for the current tax year on July 1st and January 1st, this is the same as the state’s fiscal year. But in some towns payments are made quarterly so check with town hall first.
