The exemption is not automatic and physical damage must meet a minimum degree of 15% to qualify.

Below are the Damage Levels as set by Section 11.35 of the Texas Property Tax Code:
Level
Damage Assessment
Damage Description
Exemption Percentage
I
15% < 30%

II
30% < 60%
Nonstructural damage and waterline < 18″ above floor if flooded.
30%
III
60% < 100%
Significant structural damage and waterline 18″+ above floor if flooded.
60%

The amount of the exemption is determined by multiplying the building or personal property value, as applicable, by the exemption percentage based on the damage assessment level and is then multiplied by a proration factor (the number of days remaining in the tax year after the date the governor declares the disaster is divided by 365).
Sample disaster exemption calculation:
A $200,000 home received $40,000 in physical damage from burst pipes that resulted in nonstructural damage.
  • $40,000 / $200,000 Home Value = 20%.
  • Damage assessment level 1
  • $200,000 Home value times 15% exemption percentage = $30,000
  • $30,000 time the proration factor (0.88) = $26,400 exemption amount for tax year 2021.
  • Exemption will expire January 1, 2022
A $200,000 home received $29,000 in physical damage from burst pipes that resulted in nonstructural damage.
  • $29,000 / $200,000 Home Value = 14.5%.
  • Damage does not meet the minimum threshold.
  • No exemption will be applicable to this property.
