Since Sachse spans both Dallas County and Collin County, protesting a property tax appraisal can involve navigating two similar but distinct systems.

Homeowners in Sachse receive Notices of Appraised Value each spring from either the Dallas Central Appraisal District, or the Collin Central Appraisal District, depending on which county their property is located in.

While both districts operate under the Texas Property Tax Code, their procedures and tools differ slightly.

In both counties, the deadline to file a protest is generally May 15 or 30 days after the notice is sent, whichever is later. If that deadline falls on a weekend or legal holiday, it is extended to the next business day. Property owners must submit a written protest identifying themselves, the property and the reason for dissatisfaction.

In Dallas County, protests for residential and commercial properties can be filed beginning April 15, including through the district’s online system, uFile, https://rb.gy/q8hzhx

The district does not accept protests by email or fax. Online submissions must be completed by midnight on the filing deadline, while mailed protests must be postmarked by that date and in-person submissions must be delivered before offices close.

Collin County allows protests to be filed by mail, in person, drop box or, for eligible property owners, through an online eFile system, https://onlineportal.collincad.org

A personal identification number included on the appraisal notice is required for online filing.

Once a timely protest is filed, the case moves to the Appraisal Review Board, or ARB, an independent panel that hears disputes between property owners and appraisal districts. Both counties are required to provide at least 15 days’ notice of the hearing date, time and location.

Hearings typically take place from mid-May through early July. In Collin County, hearings are conducted at the appraisal district’s offices in McKinney, with multiple panels hearing cases simultaneously. Dallas County follows a similar structure, with hearings that resemble informal court proceedings and typically last about 15 minutes.

Before the hearing, property owners have the right to review the evidence the appraisal district plans to present. They may also submit their own documentation, such as comparable sales data, repair estimates or independent appraisals, to support their opinion of value.

Some disputes may be resolved before a formal hearing. In Dallas County, property owners who submit documentation through the uFile system may receive a settlement offer from an appraiser after review. If an agreement is reached, a formal ARB hearing may not be necessary.

If no resolution is reached, the ARB panel will hear testimony from both sides and issue a decision based on the evidence presented. Written notice of the final order is later sent by certified mail, along with information about further appeal rights.

By July 20, appraisal review boards must complete the majority of hearings and approve appraisal records, with only a small portion of properties remaining under protest.
