CT HB05161

Municipalities with populations of 25,000 or more must require nonresident rental property owners, project-based housing providers, or agents in charge to report identifying information (name, date of birth, residential address, driver's license or government ID number) to the tax assessor

Nonresident owners include individuals, corporations, partnerships, trusts, or other entities that own rental property but do not reside there, as well as controlling participants who exercise day-to-day financial or operational control

Address changes must be reported within 21 days; if no address is filed, the property tax billing address becomes the default for service of municipal or state orders

Violations carry fines of $250 to $1,000, increased from the previous infraction classification

All reports submitted to tax assessors are confidential and exempt from public disclosure under Connecticut's Freedom of Information laws; effective date is October 1, 2026
