Quadrennial Form Filing Requirements
Connecticut General Statutes §12-81(7), (10), (11), and (16) require the filing of a Tax Exempt Return seeking property tax exempt status. This also requires a quadrennial filing from the initial application assessment year. Connecticut General Statute §12-87 requires exempt organizations to report any additional property acquired since the filing of the initial application or the last previous quadrennial report on a supplemental tax return.
Organizations initially requesting a property tax exemption during the interim years should check the box labeled INITIAL APPLICATION. The quadrennial filing period remain the same when filing in an interim year.
The following documentation is required to be attached to the application:
A copy of the Organization's Internal Revenue tax exempt certificate under Section 501(c) or 501(d) of the IRS Code
Copies of the Organization’s By-laws and or Charter, if applicable.
