The 2026 Montgomery County Protest Deadline Is Almost Here
If you own property in Montgomery County — The Woodlands, Conroe, Magnolia, Willis, New Caney, Montgomery, or anywhere else in the county — and you think your appraised value is too high, Texas law gives you the right to protest. But that right expires on a fixed date. Miss it, and you're stuck with whatever the Montgomery Central Appraisal District (MCAD) has decided your home is worth — and the tax bill that comes with it.
Here's what Montgomery County homeowners need to know about the 2026 protest deadline.
The Standard Deadline: May 15, 2026
For most Montgomery County homeowners, the deadline to file a property tax protest is May 15, 2026. This is set by Texas state law and applies to residential properties across the state.
Your protest must be received by MCAD on or before this date — not postmarked. If you're filing by mail, send it well in advance. Better yet, file online through MCAD's online protest system at mcad-tx.org to avoid mail delays entirely.
The 30-Day Rule: Your Safety Net
There's one important exception under Texas Tax Code Section 41.44(a)(1). If MCAD mails your appraisal notice after April 15, 2026, you get 30 days from the date on the notice to file your protest — even if that date falls after May 15.
How it works in practice:
- Notice dated April 10, 2026 → deadline is May 15, 2026 (standard deadline)
- Notice dated April 22, 2026 → deadline is May 22, 2026 (30 days from the notice)
- Notice dated May 3, 2026 → deadline is June 2, 2026 (30 days from the notice)
Always check the date on your appraisal notice. The 30-day rule can give you extra time, but only if your notice was mailed late. Don't assume — verify.
What Happens If You Miss the Deadline?
If you miss the deadline, MCAD will not accept your protest. There are no extensions, no grace periods, no appeals. Your appraised value for 2026 becomes final, and your tax bill will be calculated based on that number.
Montgomery County's combined tax rate runs around 2.0-2.1% depending on your city, school district, and MUD. That means a $40,000 over-assessment can cost you roughly $820 in unnecessary property taxes for the year. In high-value neighborhoods like The Woodlands and Carlton Woods, where home values are higher, the absolute dollar gap from an over-assessment can be much larger — easily $1,500 to $3,000 a year for a meaningful over-assessment.
How to File Your Protest With MCAD
Filing is simpler than most people think. You don't need a lawyer, and the filing itself is free. Montgomery County homeowners have three options:
Option 1: File Online (Recommended)
MCAD's online protest system is accessible from mcad-tx.org. Most protests are filed this way. You'll need your property account number (it's on your appraisal notice) and some basic information.
Benefits of filing online: - Instant confirmation that your protest was received - Many protests can be settled through evidence review without an in-person hearing - You can upload evidence documents directly
Option 2: File by Mail
Download the protest form from mcad-tx.org or use the one included with your appraisal notice. Fill it out, sign it, and mail it to the address listed on the form.
Important: Mail it at least 7-10 days before the deadline. Consider sending it via certified mail so you have proof of delivery.
Option 3: File in Person
You can bring your completed protest form directly to the MCAD office in Conroe. This guarantees delivery but requires a trip and possible wait time.
What to Include When You File
The filing itself is straightforward. You need to:
- Identify your property (account number or address)
- State the reason for your protest (most homeowners choose "value is over market value")
- Sign and date the form
You do not need to include your evidence when you file. Evidence — comparable sales, photos, property record corrections — comes later, either online or at your hearing. The filing just gets you in the door.
That said, start gathering evidence right away so you're not scrambling later.
A Simple 2026 Timeline for Montgomery County
- Early April: Receive your appraisal notice from MCAD. Review it immediately.
- Mid-April: Decide whether to protest. Look up comparable sales and check your property record for errors.
- Late April: File your protest online through mcad-tx.org. Don't wait until the last minute.
- May – July: Settle through online review, or attend your informal hearing and/or ARB hearing.
- After decision: If successful, your appraised value drops and so does your tax bill.
Why Filing Early Beats Filing Late
Montgomery County processes tens of thousands of protests each year, and the volume keeps climbing as the county grows. Filing early in April or early May gives you real advantages:
- No risk of missing the deadline due to illness, travel, or forgetfulness
- Earlier hearing dates — MCAD schedules in the order protests are received
- More time to gather evidence and build a strong case
- Informal settlement opportunities before your formal ARB hearing
In master-planned areas like The Woodlands, comparable sales data tends to be especially clean — homes are built to similar specs and recent sales are easy to identify, which makes it easier to build a well-supported protest.
