Calculation of exemption

General municipal and school district taxes:

The schedule to be followed in calculating the exemption depends on which exemption applies to the project that meets energy efficiency and environmental design standards in one of three categories specified in the LEED or equivalent program: certified/silver; gold; or platinum (standards for each category can be found at or their functional equivalents standards under the acceptable alternative programs, as certified by the accredited professional).  For all three exemption schedules below, the exempt amount for each year is calculated as a percentage of the increase in assessed value attributable to the construction or reconstruction meeting the LEED or equivalent standards in the initial year of the term of each exemption schedule.  The following percentages of such increase in assessed value should be applied as follows:

 Year and percentage of exemption
Year of exemption Percentage of exemption
(1) Certified/Silver (2) Gold (3) Platinum
1 100 100 100
2 100 100 100
3 100 100 100
4  80 100 100
5  60  80 100
6  40  60 100
7  20  40  80
8  0  20  60
9  0   0  40
10  0   0  20
