The deadline to file a property tax protest in Rockwall County is May 15 or 30 days after your Notice of Appraised Value is mailed, whichever is later. You can file online at https://www.rockwallcad.com, by mail, or in person at the Rockwall CAD office. Don't wait until the last day — filing early gives you more scheduling flexibility for your hearing.

File Form 50-114 with Rockwall CAD. You must own and occupy the property as your primary residence as of January 1. The deadline is April 30. A late homestead exemption application is accepted if it is filed not later than two years after the delinquency date for the taxes on the homestead, which is usually February 1 of the year after the tax year (Tax Code §11.431, §31.02). A late application for a tax year before 2025 gets that year's school exemption amounts, which were lower. A homestead exemption reduces your school district taxable value by $140,000, and you qualify for the 10% annual appraisal cap.

The strongest evidence includes: (1) comparable property sales within 1 mile that sold for less than your appraised value, (2) photos showing condition issues like foundation cracks, roof damage, or outdated interiors, (3) your property's per-square-foot value compared to neighbors (for unequal appraisal arguments), and (4) any errors in your property record (wrong square footage, room count, etc.).

At the Appraisal Review Board hearing, you present your evidence to an independent panel. First, you'll have an informal meeting with an appraiser from Rockwall CAD who may offer a settlement. If you don't agree, you proceed to the formal hearing where panel members review both sides and make a binding decision. The process typically takes 15-30 minutes.

Yes. Texas law gives you the right to protest your property's appraised value every year, even if you protested last year. Appraisal districts reassess all properties annually, so last year's reduction doesn't carry forward — you should review your new value each year and protest if it seems too high.

Yes. Rockwall CAD considers new construction sales as comparables. If new homes in your area sold for less than your appraised value, that's strong protest evidence. Conversely, if new homes are selling at premium prices, the appraisal district may use those to justify higher values for existing homes — in which case, focusing on condition differences between your home and new construction is important.

You can pay Rockwall County property taxes online, by mail, or in person at the Rockwall CAD. Online payments typically accept credit card (with a convenience fee) and eCheck. The payment deadline is January 31 (or the next business day when it falls on a weekend or holiday) — after that, penalties and interest begin accruing at approximately 7% in February and increase monthly. If you need more time, ask about installment payment plans.

Beyond the standard homestead exemption, Rockwall County homeowners may qualify for: (1) Over-65 exemption — an additional $60,000 off school taxable value plus a tax ceiling that freezes your school tax amount, (2) Disabled person exemption — similar benefits to over-65, (3) Disabled veteran exemption — partial to full exemption based on disability rating, and (4) Agricultural (ag) exemption for qualifying rural properties.
