|  | (a)  Notwithstanding the requirements of Section 25.18 and | 
|  | regardless of whether the appraisal office has appraised the |

|  | year, an appraisal office may increase the appraised value of a | 
|  | residence homestead for a tax year to an amount not to exceed the | 
|  | lesser of: | 
|  | (1)  the market value of the property for the most | 
|  | recent tax year that the market value was determined by the | 
|  | appraisal office; or | 
|  | (2)  the sum of: | 
|  | (A)  five [ 10] percent of the appraised value of | 
|  | the property for the preceding tax year; | 
|  | (B)  the appraised value of the property for the | 
|  | preceding tax year; and | 
|  | (C)  the market value of all new improvements to | 
|  | the property. | 
|  | SECTION 2.  This Act applies only to the appraisal for ad | 
|  | valorem tax purposes of residence homesteads for a tax year that | 
|  | begins on or after the effective date of this Act. | 
|  | SECTION 3.  This Act takes effect January 1, 2010, but only | 
|  | if the constitutional amendment proposed by the 81st Legislature, |

|  | maximum appraised value of a residence homestead for ad valorem tax | 
|  | purposes to 105 percent or more of the appraised value of the | 
|  | property for the preceding tax year is approved by the voters.  If | 
|  | that amendment is not approved by the voters, this Act has no | 
|  | effect. |
