It's true, the Value Adjustment Board(s) have been in effect for years in Florida's counties. However, it has only been within the past couple of years (this past year in particular), that market values have risen so sharply that people have actually gone to the trouble of petitioning their property assessments.
And while I think it is a good effort on the part of the Governor and the State Legislature to attempt to establish some type of property tax reform, I believe that the system we already have in place would work just fine if our collective taxing authorities would stop "backing in" to their budgets. And whether they like to hear it or not, that's exactly what they do. Rather than determine what their budget needs are going to be for the upcoming year, they simply sit back and wait to receive the preliminary tax roll figures from the county property appraiser, and then calculate how much money they'll have to "play with" using their current millage rates.
That's not how it is supposed to work, and, IMHO, it demonstrates laziness on the part of the taxing authorities.
Perhaps the easiest thing the State could do would be to only allow the taxing authorities to increase their budgets by the rate of growth their county or municipality has seen from the previous year, plus the Consumer Price Index, or roughly 3%.
This way the taxing authorities could easily project their budgets, and "craziness" in the market, such as what we've all seen over the past couple of years, would not have such a dramatic affect on property taxes.
And while that may not be a perfect solution (even though I personally think it comes pretty darn close), it sure beats trying to reinvent the wheel.
