What is the 4-Step Prep Checklist?
Gather these four items before starting your application to avoid session timeouts:
1. Texas ID
Must be updated to match your new property address exactly.
2. Account Number
Your 13-digit HCAD account number (found on your deed or tax bill).
3. Occupancy Date
The exact date you moved in and claimed the home as your primary residence.
4. Supporting Docs
Have your vehicle registration, utility bill, or trust documents handy if prompted.
How does the $140k vs. 20% math work?
The updated tax relief laws provide two distinct benefits for homeowners in Harris County:
- $140,000 School Tax Exemption: Every eligible homeowner gets $140,000 deducted from their home's assessed value before school taxes are calculated.
- 20% Harris County Exemption: In addition to the school tax break, you receive a flat 20% off the assessed value for the county portion of your property taxes.
- Senior Bonus: Homeowners 65+ get a total of $200,000 off school taxes and a 'Tax Freeze'.
Example: On a $350k Houston home, you save approximately $1,400 per year with the new $140k exemption.
