Formula

How the calculation works

Estimated new annual tax equals assessed value multiplied by tax rate, minus exemptions or credits. Monthly tax is annual tax divided by 12. Monthly change compares new monthly tax with current monthly tax.

Example calculation

A $450,000 assessed value at a 1.2% tax rate equals $5,400 annual tax before exemptions. If current annual tax is $4,200, the monthly tax change is about $100.
