3. Current Tax Exemptions & Statutory Limitations
Property tax bills reflect two distinct types of CAD adjustments: local taxing jurisdiction exemptions (which reduce taxable value below appraised value) and statutory appraisal limitations (which limit the annual growth of appraised value itself). Each taxing entity establishes its own exemption amounts and tax rates.
The current CAD record shows a homestead exemption. Reduces Rockwall ISD taxable value by $140,000 (from $517,349 net appraised value to $377,349 school taxable value). Current owner’s exemption, not guaranteed to transfer to buyer.
Statutory 10% limitation on annual increase in appraised value for qualifying residence homestead (Texas Tax Code § 23.23). This is an appraisal-stage limitation, not a local taxing jurisdiction exemption.
Each taxing jurisdiction may apply its own exemptions, limitations, and taxable-value adjustments. The figures shown reflect the current CAD record. Specific exemption details are displayed when available from the source. A buyer’s exemptions and future tax obligations may differ.
4. Value After CAD Reductions
This is where CAD reductions, exemptions, limitations, or special-use valuation may affect the value used for tax calculations.
CAD Market Value $599,922 − All Current CAD Reductions -$82,573 = Current Taxed Starting Point $517,349
This reflects the CAD net appraised value after current CAD reductions. Individual taxing units may use different taxable values when exemptions apply.
Taxable-value reduction for applicable school district (Rockwall ISD); current owner’s exemption, not guaranteed to transfer to buyer. Other local taxing units on this record apply $0 exemption reduction (taxed at $517,349 net appraised value). Separate from -$82,573 10% homestead cap already reflected in the $517,349 net appraised value.
5. Who Taxes It?
These are the local entities included in the current CAD/tax estimate. A property tax bill can include a city, county, school district, municipal utility district, public improvement district, or other special district. Each entity may use its own taxable value, rate, and exemption treatment.
| Entity | Taxable Value | Rate (per $100) | Est. Tax (No Ex.) | Savings | Est. Tax (Current) |
|---|---|---|---|---|---|
|
City
CITY OF ROCKWALL |
$517,349 | 0.2575 | $1,332 | — | $1,332 |
|
County
ROCKWALL COUNTY |
$517,349 | 0.2510 | $1,299 | — | $1,299 |
|
School District
ROCKWALL ISD |
$377,349 (H) | 1.0669 | $5,520 | -$1,494 | $4,026 |
(H) Taxable reduction reflected in school district taxable value.
Each taxing jurisdiction may apply its own exemptions, limitations, and taxable-value adjustments. The figures shown reflect the current CAD record. Specific exemption details are displayed when available from the source. A buyer's exemptions and future tax obligations may differ.
6. Estimated Tax Bottom Line
Est. Taxes (No Exemptions) $8,150 − Est. Tax Reductions / Savings $1,494 = Est. Taxes (With Current Exemptions) $6,657
The current CAD tax estimate shows exemptions and adjustments reduce the estimated annual taxes by about $1,494. Estimated taxes without exemptions are calculated by applying each jurisdiction's tax rate to its pre-exemption taxable value. Exemption savings represent the difference between this unexempted estimate and the county's current tax estimate. Taxable values and tax rates vary by jurisdiction. Future taxes depend on buyer qualification and future adopted rates.
The current tax estimate reflects a homestead exemption on the property's present CAD record. That exemption does not automatically transfer to a new owner; a buyer must qualify for their own exemptions. For comparison, the current estimate is $6,657 with the exemptions shown today and $8,150 without exemptions. Actual future taxes will depend on buyer eligibility, future appraised values, and adopted tax rates.
7. CAD Values Over Time
YOY Change reflects the change in CAD Market Value from the prior appraisal year. Taxed / Appraised reflects the CAD net appraised value after CAD reductions, or the certified capped appraisal value where jurisdictions differ. Individual taxing units may use different taxable values when exemptions apply.
| Year | Land | Impr. | Market | Taxed / Appraised | YOY Change |
|---|---|---|---|---|---|
| 2021 | $163,860 | $158,570 | $322,430 | $321,233 | +$30,400 / +10.41% |
| 2022 | $340,310 | $184,480 | $524,790 | $353,356 | +$202,360 / +62.76% |
| 2023 | $442,403 | $176,248 | $618,651 | $388,692 | +$93,861 / +17.89% |
| 2024 | $307,981 | $204,582 | $512,563 | $427,561 | -$106,088 / -17.15% |
| 2025 | $425,388 | $198,889 | $624,277 | $470,317 | +$111,714 / +21.80% |
| 2026 | $425,388 | $174,534 | $599,922 | $517,349 | -$24,355 / -3.90% |
8. List Price vs CAD Value
The current list price and the county’s CAD market value are not the same thing. CAD market value is used for property-tax context and may lag the open market, reflect prior protests, exemptions, caps, agricultural or special-use treatment, or other appraisal district methods.
How does the list price compare with the CAD value?
CAD values are appraisal-district values used for property-tax purposes and can differ from current asking prices and eventual sale prices.
Current List Price $700,000 − Current CAD Market Value $599,922 = Over CAD Value +$100,078 (+16.7%)
A sale price can become part of the appraisal district’s future evidence. A buyer’s future taxable value and tax bill may change after purchase, especially if exemptions, caps, or special-use valuation change.
For tax planning, buyers should confirm future taxable value, exemptions, and special-use treatment with the appraisal district, tax office, lender, CPA, or other qualified advisor.
