How Grayson County Assesses Property

100%of market value

Assessed by: Grayson Central Appraisal District

Assessment cycle: annual

Notices typically mailed: April-May

In Texas, properties are assessed at 100% of their market value, meaning the assessed value equals the market value before exemptions are applied. For example, if your home's market value is $278,000 (the county median), at Texas's 100% assessment ratio your assessed value would be $278,000. After applying a typical $100,000 school district homestead exemption, your taxable value would be $178,000, resulting in approximately $3,720 in annual taxes at the county's effective rate of 2.09%.

The Protest Process

Appeals are heard by the Appraisal Review Board (ARB). ARB hearings in Grayson County are informal proceedings where you present your evidence to a panel of appointed citizens. You'll have the opportunity to explain why your property value should be reduced and present comparable sales, photos, or other supporting documentation. The appraisal district will also present their evidence. Hearings typically last 15-30 minutes.

1

Step 1: Review your Notice of Appraised Value when it arrives (typically April-May). Compare your property's assessed value to comparable homes in your neighborhood and note any discrepancies in property details.

2

Step 2: File your protest by May 15, 2026 or within 30 days of receiving your notice, whichever is later. You can file online at graysonappraisal.org, by mail, in-person, or via the 24/7 drop-box at the appraisal district office.

3

Step 3: Request an informal meeting with appraisal district staff to resolve your dispute before the formal ARB hearing. The Grayson Central Appraisal District offers informal meetings where you can present your evidence and potentially settle your case without attending a formal hearing.

4

Step 4: Gather evidence to support your protest, including comparable sales data from similar properties that sold for less, photos showing property condition issues, repair estimates, and documentation of any errors in the appraisal district's records (incorrect square footage, missing defects, etc.).

5

Step 5: Attend your Appraisal Review Board (ARB) hearing if the informal meeting doesn't resolve your protest. Present your evidence clearly and professionally. ARB hearings are open to the public and scheduled throughout the protest season.

6

Step 6: Receive the ARB's decision in writing. If you disagree with the ARB's determination, you have the right to appeal to district court, request binding arbitration, or appeal to the State Office of Administrative Hearings (SOAH) depending on your property type and protest grounds.

7

Step 7: If you pursue further appeals and are still unsatisfied, you may take your case to district court for judicial review as a final option.

How much can I save by protesting my property taxes in Grayson County?
Based on 2023 data, property owners in Grayson County who successfully protested their assessments saved an average of $463 per account. However, savings vary widely depending on how much your property was overvalued and the strength of your evidence.

What evidence do I need for a successful property tax protest in Grayson County?
To build a strong property tax protest in Grayson County, you should gather comparable sales data from at least three to five similar homes in your neighborhood that sold for less than your assessed value within the past year. Include photos documenting any property condition issues, deferred maintenance, or defects that might reduce your home's value. Bring copies of repair estimates or inspection reports that identify needed work. Review the Grayson Central Appraisal District's property records for your home and document any errors in square footage, room count, garage size, or other features. You may also include a professional appraisal if you have one. Present your evidence in an organized format, such as a comparison grid showing how your home differs from higher-valued comparable properties.
Can I get an informal hearing before my ARB hearing in Grayson County?
Yes, Grayson County offers informal meetings with appraisal district staff as a way to resolve disputes before attending a formal Appraisal Review Board hearing. During the informal meeting, you can present your evidence and discuss your concerns directly with an appraiser who may have the authority to adjust your property's value on the spot if your evidence is compelling. Many property owners find that informal meetings result in faster resolutions and avoid the need for a formal ARB hearing. To request an informal meeting, contact the Grayson Central Appraisal District at 903-893-9673 after filing your protest. These informal settlements can save you time while still achieving significant property tax reductions. In 2024, informal protests in Grayson County resulted in $130,000 in homeowner savings.
