Brookfield officials are looking to crack down on residents who have their cars registered elsewhere.  Bids are being sought by the Tax Assessor's Office to identify these vehicles and collect owed revenues.  First Selectwoman Tara Carr says she hears frequently about an uptick in out-of-state license plates in school pick-up lines and at local sporting fields. Carr says the assessor’s office does a great job, but through COVID and just people becoming more transient, the office needs the support.  Only a few firms specialize in the use of technology capable of identifying vehicles owned by local residents but that are not yet registered in Brookfield.  Bethel, New Milford and others have hired Shelton-based Municipal Tax Services, which collects 50 percent of vehicle and property taxes found in the initial years of service.  Bethel reported finding $115,000 in tax revenue from a total of 440 vehicles found not to be registered in town since January 2021.  New Connecticut residents must register their cars within 60 days of moving.
