Think your value is too high?

Asking for a lower market value

Free review: Talk with your county appraiser first. It is free.
Formal appeal: Your County Board of Equalization, filed through the county clerk. You can appeal further to the Board of Tax Appeals or district court.
Deadline: File with the county clerk by the fourth Monday in June. The board meets from that Monday through the second Monday in July.
Good to know: It is not confirmed whether the board can raise your value, so be aware that it might.

A formal appeal reopens your whole value: the board can raise it as well as lower it. Bring recent sales of similar homes.

What can't come off

Charges you can't remove

Value above the 50% / $125,000 homeowner's exemption.
Tax on acreage over one acre, or on a home that is not your primary home.
Solid waste, irrigation and other fees.
Interest and late charges once a half is late.
The circuit breaker is capped at $1,500 and needs the homeowner's exemption.
