Personal Property used in commercial enterprises, such as machinery, equipment, furniture, tools, fixtures, computers, cables, conduits, pipes, 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.
Personal Property Declaration - Online Filing
If you received an invitation to file online, please follow the link below. Create an account using your access code and follow the instructions to complete your filing. The deadline for filing is November 1, 2023.
Declaration forms are available from the Assessor's Office for businesses to summarize their property by type and year acquired. The Assessor applies depreciation factors to estimate the current values.
Declarations mailed to businesses during September are due to the Assessor's Office by November 1 every year. If a business owner needs to request an extension for filing the form, the written request for an extension must be received by the Assessor's Office by November 1.
Connecticut law levies a 25 percent penalty assessment for failure to file a declaration, omitting property or filing a declaration late after November 1 without having been approved by the Assessor for filing an extension. Assessment notices are mailed at the end of January.
Unregistered or Out-of-State Registered Motor Vehicles
Motor vehicles that do not have a current Connecticut registration are subject to personal property tax. Complete the Declaration of Personal Property for Motor Vehicles and return to the Assessor's Office by November 1 annually.
Appeals of the assessment must be made to the Board of Assessment Appeals by February 20, except when a one month extension is granted. It is recommended that business owners first speak with the Assessor's Office before filing a formal appeal, to correct any errors or misinformation.
