Common Mistakes When Filing Online

Avoid these errors that can weaken or disqualify your protest:

1. Missing the May 15 deadline - File early to avoid last-minute issues
2. Missing the 5-day evidence deadline - Evidence must be uploaded within 5 calendar days
3. Not checking all applicable boxes - Select all relevant protest reasons
4. Confusing market value vs. appraised value - Know what you're protesting
5. Using inaccurate comparable sales - Verify HCAD's comps against actual data
6. Uploading vague evidence - Photos and estimates need context
7. Not checking for data errors first - Fix wrong square footage or features
8. Missing your ARB hearing - Attend or file a written explanation within 4 days
