New Haven's property taxes are on a 5 year phase-in. You can find out more at: http://www.cityofnewhaven.com/TaxCollector/index.asp. You can also go to the Finance Department and it will calculate your taxes based on your old assessment and your new assessment.
Of course, there are deductions given to veterns and for other special needs..\
