Personal Property Assessments

Personal Property used in commercial enterprises, such as machinery, equipment, furniture, fixtures, computers, cables, conduits, pipes, tools, leasehold improvements, supplies, video tapes, horses, etc., is subject to assessment in Connecticut and must be declared annually with  costs and acquisition dates.  Business inventory is not taxable. Declaration Forms  are available from the Assessor for businesses to summarize their property by type and year acquired.   The Assessor applies depreciation factors to estimate current values. 

Personal Property Declaration Forms 

Declarations mailed to businesses during September are due to Assessor by November 1st every year.  We do not accept emailed as we cannot guarantee the security, we do offer online filling which is outlined below.   If a business owner needs to request a 6-week extension for filing the form, the written request for an extension must be received by the Assessor's Office by November 1st.  Connecticut law levies a twenty-five percent penalty assessment for failure to file a declaration, omitting property, or filing a declaration late after November 1st without having been approved by the Assessor for a filing extension.  Assessment notices are mailed at the end of January.

It is recommended that business owners first speak with the Assessor's Office before filing a formal appeal, to correct any errors or misinformation. If an owner believes that the personal property of a business has been incorrectly valued by the Assessor, the value may be appealed to the Board of Assessment Appeals.
