The Office of Policy and Management (OPM) has limited authority in the area of property (real, personal, motor vehicle) assessment and taxation. Assessment and taxation are administered on the municipal level and one should check with their local assessor and tax collector for more information. OPM issues guidelines for property tax exemption and tax credit programs for which municipalities receive state reimbursement for their tax losses. OPM determines annual personal property taxes for certain companies that provide telecommunications services. OPM also prescribes the application that a taxpayer uses to obtain maritime heritage land classification.
OPM does not have the authority to waive taxes or the interest on delinquent taxes. We do not have the authority to override a determination that a local assessor or tax collector makes, nor provide legal opinions about assessment and taxation legislation that municipal officials administer. Because property taxation affects the vast majority of

Local governmental officials administer the property assessment and taxation. State law governs the manner in which a town or city assessor determines property assessments and the procedures that tax collectors use to collect property taxes. State law also authorizes property tax exemptions, credits and abatements.
Some cities and towns contain specific taxing districts, such as fire districts, that provide services that the city or town does not provide. The assessment of property that a city or town assessor determines is the basis for the tax that a district collects.
The grand list is a record of all taxable and tax exempt property in a taxing jurisdiction as of the assessment date. Assessors generally file the grand list by the end of January, but some may do so by the end of February. If the assessment of real estate or personal property, other than a motor vehicle, increases from one assessment date to the next, an assessor must send an increase notice to the affected taxpayer (Chapter 203 - Sec. 12-55).
A taxpayer who disagrees with an assessor’s determination regarding an assessment has the right to submit a written request for a hearing to a local board of assessment appeals (Chapter 203 - Sec. 12-111). The date for submitting a hearing request is either February 20 or March 20, depending on when the grand list is completed; hearings occur in March or April and their duties must be concluded by March 31 or April 30. Boards of assessment appeals also meet at least once during the month of September to hear appeals related to motor vehicle assessments (Chapter 203 – Sec. 12-112). A taxpayer must appear at a hearing before the board of assessment appeals, or must ensure that someone appears on the taxpayer’s behalf (Chapter 203 – Sec. 12-113). If a taxpayer disagrees with a determination of a board of assessment appeals, the taxpayer may file an appeal with the superior court for the judicial district in which the property is located (Chapter 203 – Sec. 12-117a).
After the board of assessment appeals finalizes determinations for hearings held in March or April, a taxing jurisdiction determines the amount of property tax revenue that it will need for the upcoming fiscal year and sets a mill rate. Multiplying the mill rate (the basis for which is a thousandth of a dollar) by a property’s net assessment results in the property tax. The net assessment of a property is the assessment minus all exemptions for which a taxpayer qualifies.
Although a taxpayer establishes a property tax liability as of October 1, a tax collector does not mail a tax bill for that liability until the following June. (A tax collector may mail a tax bill even later if there is a delay in establishing the mill rate.) Also, tax collectors do not mail tax bills for some motor vehicles until the following January. While state law requires tax collectors to mail tax bills, it also specifies that a tax collector’s failure to do so does not invalidate the tax. Failure to receive a tax bill does not exempt you from payments of all taxes and all interest charges (Chapter 204 - Sec. 12-130).
Local jurisdictions determine whether property taxes are due in one or more installments. State law provides a 30-day grace period for a property tax payment (Chapter 204 - Sec. 12-142). If a taxpayer pays a tax after the 30-day grace period, the payment is delinquent. State law requires tax collectors to add interest, at the rate of 1 ½ percent per month or any portion of a month, to a delinquent tax bill (Chapter 204 - Sec. 12-145). For example, a tax due July 1 is payable on or before August 1. If the tax is paid August 2, interest equals 3% (1 ½ percent for July and 1 ½ percent for August).
Interest becomes part of the property tax when a tax collector imposes it. Tax collectors cannot accept a partial payment of a delinquent tax that is less than the total of the accrued interest on the principal of the tax. Each payment reduces the interest before reducing the principal (Chapter 204 - Sec. 12-146).
Tax collectors may issue tax warrants to collect outstanding property taxes (Chapter 204 - Sec. 12-135). They may initiate foreclosure proceedings with regard to delinquent real estate taxes (Chapter 204 - Sec. 12-157). They may report taxpayers who are delinquent in paying motor vehicle property taxes to the Department of Motor Vehicles, in which case the taxpayer cannot obtain a registration or registration renewal without providing proof of payment of the outstanding tax. Municipalities may refer delinquent taxpayers to collection agencies and may also use other means to collect taxes that are delinquent.
State law allows for the collection of property taxes within 15 years after a tax due date (Chapter 204 - Sec. 12-164).
The chief elected official of towns, cities and boroughs may abate a tax or interest for a person who is poor and unable to pay, or for a railroad company under certain circumstances (Chapter 204 - Sec. 12-124). A municipality’s legislative body (or its board of selectmen in a town in which the legislative body is a town meeting) may abate the property tax for an owner-occupied residential dwelling, to the extent that the tax exceeds 8% or more of the total income of all occupants (Chapter 204 - Sec. 12-124a).
A tax collector may waive the interest on delinquent property taxes if the tax collector and the assessor, jointly, determine that the delinquency is attributable to an error by the tax assessor or tax collector and is not the result of any action or failure to act on the part of the taxpayer (Chapter 204 - Sec. 12-145). Also, state law requires a municipality to waive interest on a delinquent tax for any taxpayer who received compensation from the State of
An assessor has the authority to correct a clerical error or omission in a property assessment within the time period that state law allows (Chapter 203 – Sec. 12-60). An assessor also has the authority to issue a certificate of correction regarding personal property within a specified time period and to issue corrections regarding certain motor vehicles (Chapter 203 – Section 12-57).
If a correction occurs after a tax payment is made, a taxpayer may send a written request for a refund of an overpayment to the tax collector, not later than three years from the date the tax was due (Chapter 204 – Sec. 12-129). State law provides a more extensive time period for the recovery of a tax overpayment by a member of the
Real estate is all land and all improvements (such as buildings, fences, and paved driveways), as well as easements to use air space (Chapter 203 - Sec. 12-64).
With the exception of certain classified land, the assessment of each parcel of real property represents 70% of its estimated fair market value as of the date of a revaluation (Chapter 203 - Sec. 12-62, Sec. 12-62a and Sec. 12-63). Assessors value classified farm, forest, open space and maritime heritage on the basis of use, rather than on a fair market value basis (Chapter 203 - Sec. 12-107b through Sec. 12-107f and Public Act 07-127).
When a revaluation occurs, an assessor establishes the current fair market value of all real estate, in order to equalize the tax burden among property owners. While assessors must revalue all real estate not later than five years after the October 1 effective date of the previous revaluation, they may revalue real estate more often than once every five years (Chapter 203 - Sec. 12-55 and Sec. 12-62).
Before a revaluation becomes effective, taxpayers may receive questionnaires so that they may verify information concerning their properties. At least once in every 10 assessment years, an assessor (or an assessor’s designee) may request a taxpayer’s permission to enter a building in order to verify its condition, and other information the assessor needs, to establish its fair market value (Chapter 203 - Sec. 12-63). State law also imposes reporting requirements that affect owners of certain income-producing real estate in conjunction with revaluations (Chapter 203 - Sec. 12-63c).
Cities and towns may choose to phase in real estate assessment increases when implementing a revaluation. They may phase in all or a portion of the increase for up to five years (Chapter 203 – Sec. 12-62c).
Upon the completion of new construction (including building additions) in any year after the effective date of a revaluation, a taxpayer’s property assessment increases. The increase represents the portion of an assessment year during which the newly constructed improvement may be used for its intended purpose (Chapter 203 - Sec. 12-53a). Under certain circumstances, a real estate assessment reduction may occur during an assessment due to the demolition of a building (Chapter 203 - Sec. 12-64a).
In general, personal property is anything that is moveable and is not a permanent part of real estate, including items such as business-owned furniture, fixtures, machinery or equipment, as well as horses and unregistered motor vehicles and snowmobiles that anyone owns (Chapter 203 - Sec. 12-71).
A taxpayer must file a Personal Property Declaration with the assessor of the city or town in which personal property is subject to taxation by November 1 annually (Chapter 203 - Sec. 12-41). An assessor may grant a taxpayer an extension of up to 45 days to file a declaration (Chapter 203 - Sec. 12-42). Nonresident taxpayers must also file a declaration (Chapter 203 - Sec. 12-43).
Lessors of personal property must also file a report with assessors by November 1, annually. This requirement affects any personal property (other than a
On a Personal Property Declaration, a taxpayer provides information concerning the year of acquisition of personal property, as well as the original cost of acquisition, freight and installation. Assessors apply depreciation to the total cost a taxpayer declares to obtain the depreciated value of personal property. The assessment of the property is 70% of the depreciated value.
If a taxpayer files a Personal Property Declaration subsequent to the date it is due, the assessor adds a 25% assessment penalty to the taxpayer’s assessment. A 25% assessment penalty can also be applied if a taxpayer fails to file a declaration, in which case an assessor uses the best information available to determine the value of the taxpayer’s personal property (Chapter 203 – Sec. 12-41 and Sec. 12-42).
An assessor (or an assessor’s designee) may conduct an audit regarding a taxpayer’s personal property. If an audit reveals that a taxpayer omitted property from a declaration or did not accurately report personal property costs, state law provides for a 25% penalty of the assessed value. Interest is applicable to the tax for such property from the tax due date for the assessment year to which the audit relates (Chapter 203 – Sec. 12-53).
In general, motor vehicles are subject to taxation in the city or town where, in the normal course of their operation, they most frequently leave from and return to or remain, although state law provides some exceptions to this general rule (Chapter 203 – Sec. 12-71).
The assessment of a motor vehicle is 70% of its average retail value. Generally, assessors use average retail values that the National Automobile Dealer’s Association (NADA) compiles annually. Assessors are responsible for determining the value of any motor vehicle for which the NADA Guide does not provide an average retail value.
All motor vehicles a taxpayer owns on an assessment date are subject to taxation, regardless of whether the Department of Motor Vehicles issues a
A property tax reduction or credit is available when a taxpayer sells a motor vehicle and does not replace it with another vehicle. If a taxpayer replaces one vehicle with another, the assessor reduces the assessment of the replacement vehicle on the supplemental grand list to reflect the credit (Chapter 203 - Sec. 12-71b).
A property tax reduction or credit is also available for a vehicle which is sold, totally damaged, stolen or registered in another state. Taxpayers must claim this credit within the time period that state law prescribes (Chapter 203 - Sec. 12-71c).
Beginning with the 2015 assessment year, the law allows municipalities and special taxing districts to tax motor vehicles at a different rate than other taxable property, but it imposes a cap on the mill rate for motor vehicles. The cap was 37 mills for the 2015 assessment year and 32 mills for the 2016 assessment year, 39 mills and thereafter. For fiscal year ending June 30, 2018 the cap was 39 mills. For fiscal year 2020 and thereafter, the cap is 45 mills. Pursuant to PA 22-118 Section 414, municipalities may not impose mill rates higher than 32.46 mills on motor vehicles for the assessment year commencing October 1, 2021 (Fiscal Year 22-23). It applies to any town, city, borough, consolidated town and city, consolidated town and borough, and village, fire, sewer, or combination fire and sewer districts, and other municipal organizations authorized to levy and collect taxes. This provision supersedes any special act, municipal charter, or home rule ordinance (CGS § 12-71e).
State law authorizes various property tax exemptions for
Some property tax exemptions are available only in a city or town that authorizes them via adoption of an ordinance (Chapter 203 – Sec. 12-81n through Sec. 12-81bb). Property tax abatements may also be available for certain types of new construction or rehabilitation in areas of cities or towns (Chapter 203 - Sec. 12-65 to Sec. 12-65h) and cities or towns may also authorize tax abatements of up to 50% for certain types of property uses (Chapter 203 - Sec. 12-81m).
The statutes that govern property tax exemptions set forth eligibility and application filing requirements.
