If you own a home, for example, in Harris County, you can protest your property taxes (kotei sanzei).  You can did this online and the first deadline is coming up, April 30.  From this Channel 13 News story, here are some details:  http://abclocal.go.com/ktrk/story?section=news%2Fconsumer&id=8590111

The easiest away to protest values is by using HCAD's internet-based iFile system.

Altinger explained, "When they get their scheduling notice for the hearing, they can also get the information online for what will be presented in the hearing."

Homeowners have two deadlines to file protests. The first is April 30, but if you have not gotten your property tax valuation in the mail by then, you still have until May 31 to protest. You can do all of this online.

If you have any kind of damage to your home that HCAD does not know about, like a cracked foundation, that can be used to lower your value. Also, check the value of the homes around your house and any recent sales to see if your value is higher than it should be.     

It's worth it to try!!!
