Calculating property taxes accurately

[Ismael Ayala Jr.]

Hello, I'm new to investing and active in the market. I'm in the Tampa Bay area(Hillsborough County) and I'm trying to accurately calculate property taxes. I'm seeing taxes that are much higher than the actual property tax percentage of Hillsborough County which I believe is is 1.09%. 

I understand Zillow gives estimates and is not always accurate, however,  I've confirmed numbers through the county Appraiser website. But Im only able to pull up AD Valorem taxes but not non-Ad Valorem taxes on the county website which adds more to my confusion.

Would someone knowledgeable in this area be able to walk me through a live example? I'm doing something wrong and Google answers are not helping.
