The order prohibited the reassessment from changing the total revenue raised by each of the affected taxes, which are the county real property tax, the municipality or township real property tax, and the school district real property tax. In other words, the tax RATE would be decreased to the extent the total fair market value of assessed properties INCREASED.
Here is an example. Suppose the total assessment of properties in the taxing jurisdiction before reassessment was $100. Suppose the tax rate was 5 percent. The revenue would be $5. If after the reassessment the total assessment of the properties is $150. To maintain total revenue of $5, the tax rate would be reduced to 3.33 percent.
When the reassessment was announced, and notices published on web sites, mailed to property owners, and discussed in newspaper and other articles, it was made very clear that the tax rate would need to be reduced because the overall assessments were expected to increase. And now that the reassessment is complete, aside from appeals, indeed the total assessment of properties has increased. That was bound to happen, because overall properties had been underassessed compared to fair market value.
Once the reassessment was complete, the county sent each property owner a notice of the new assessment. Technically, the county sent several notices with opportunities for property owners to challenge underlying facts, such as the size of the parcel, the number of bedrooms, and similar characteristics. After that part of the process ended, the county sent the final reassessed value, with provisions for appeal if the property owner disagreed.
It didn't take long for expressions of unhappiness to pop up on neighborhood social media sites. Some property owners complained, paraphrasing, "My assessment went up so my taxes will go up." Several property owners complained about jurisdictions having "extra money" to spend. Despite attempts by others to explain the reality, some people continued to argue that the explanations were not true facts.
One point that had been made consistently throughout the process was that the real property tax for a particular property could end up increasing, decreasing, or staying the same, depending on the change in the tax rate and the change in assessment for a particular property. How can that happen?
Here is an example. Suppose there are five properties, subject to a hypothetical rate of 5 percent:
| Property | Former assessed value | tax |
| Property 1 | 100 | 5 |
| Property 2 | 120 | 6 |
| Property 3 | 150 | 7.50 |
| Property 4 | 200 | 10 |
| Property 5 | 300 | 15 |
So the total assessed value is 870, and the total tax revenue is 43.50. Now suppose these are the new assessments:
| Property | New assessed value |
| Property 1 | 150 |
| Property 2 | 150 |
| Property 3 | 180 |
| Property 4 | 250 |
| Property 5 | 400 |
The total assessed value after reassessment is 1130. To maintain revenue at 43.50, the new tax rate must be set at 3.85 percent (after a slight rounding). Therefore, the new amount of tax for each property, compared to the pre-reassessment tax, is as follows:
| Property | New assessed value | New tax | Old tax | Change |
| Property 1 | 150 | 5.78 | 5 | +0.78 |
| Property 2 | 150 | 5.78 | 6 | --0.22 |
| Property 3 | 180 | 6.93 | 7.50 | --0.57 |
| Property 4 | 250 | 9.63 | 10 | --0.37 |
| Property 5 | 400 | 15.40 | 15 | +0.40 |
So of the five properties, taxes have increased on two and have decreased on three. Though the arithmetic can be a bit tedious for some, it is troubling that two basic principles cannot be understood. With the prohibition against using reassessments to increase total revenue, the idea that taxing jurisdictions will have “extra money” is contrary to logic and common sense. Similarly, the mere fact that the assessment on a property has increased does not mean that the tax will increase, because until the new rate is set, the required computation to make a comparison cannot be done. This, too, is a matter of logic and common sense. Too many people either lack one or both of these traits or simply refuse to make use of them. One need not understand quantum physics to understand the basic principles, and examples, of the reassessment process. Put another way, jumping to conclusions without having all the facts, or having the facts but failing to perform critical analysis, is dangerous in so many ways. These flaws, insufficient or erroneous information and failure to think rather than respond emotionally when emotion is irrelevant, are two of the underlying causes of many of the problems troubling the nation.
