The WCAD Same-Day Hearing Structure
WCAD's most distinctive feature: informal and formal hearings take place on the same day.
When you arrive for your scheduled hearing date, you first meet informally with a WCAD appraiser. If you reach an agreement, the protest is resolved. If not, you proceed immediately to the formal ARB hearing — same day, same visit. This is fundamentally different from Travis County, where informal meetings are scheduled weeks before any ARB hearing.
Virtual Hearings via RingCentral
Virtual hearings use the RingCentral platform, where you enter a digital waiting room. A WCAD representative collects your information via chat, then you meet informally with an appraiser for approximately 15 minutes. If unresolved, you are moved to a Virtual ARB Waiting Room and then into a private breakout room for the formal hearing.
Telephone hearings are also available but include only the formal ARB hearing — not the informal review.
Important: hearings are not scheduled by protest submission date. Filing early does not guarantee an earlier hearing, and WCAD warns of potentially longer-than-expected wait times.

WCAD Practical Tips
WCAD provides excellent transparency tools. You are entitled to a copy of the Chief Appraiser's evidence at least 14 days before your hearing — request it through the online form on wcad.org. WCAD also publishes explanatory guides for their comparable sales grid and equity comparable grid, which show exactly how they calculate adjustments between properties.
When you file online, you may receive the list of properties WCAD used to determine your value with a “Comparable Sales Click Here” link. Analyze these before your hearing to identify whether WCAD is comparing your home to substantially different properties — those with pools, more upgrades, or significantly different lot sizes.
Experienced protesters recommend scheduling hearings later in the season (closer to July) when more sales data is available to support your case.
