Constant Yield Tax Rate

In the last taxable year, the County real property tax rate as of July 1, 2020 was $1.10, and the certified assessment of the net assessable real property was $87,943,865,531. The assessment multiplied by the rate produced property tax revenues of $967,382,521. For this taxable year, the certified assessment of the net assessable real property is $89,683,738,048. To produce the same real property tax revenue as last year, the tax rate would have to be $ 1.0787. This rate is called the Constant Yield Tax Rate.

For this taxable year, the actual property tax rate is $1.10 which is different from the Constant Yield Tax Rate. The rate is more than the Constant Yield Tax Rate and will produce in real property tax revenues $19,102,636 more than would be produced by the Constant Yield Tax Rate.
