TAX INFO FOR NORMAL PEOPLE
A plain-English CAD, tax, exemption, parcel, and improvement snapshot from county appraisal records.
View Official CAD Page
1. CAD Big Picture: Land + Improvements = Market Value
This shows what the CAD market value is made of. Appraisal districts usually separate value between the land and the improvements. Improvements may include the home, garages, shops, patios, pools, decks, storage, and other structures.
3. Exemptions That Lower Taxable Value
Exemptions and CAD reductions can lower the taxable value used to estimate property taxes. A common example is a homestead exemption for an owner-occupied home. Some properties may also have agricultural or special-use valuation, where part of the land is taxed differently than land valued for development. Not every taxing entity applies the same exemption or reduction.
The current CAD record shows a disabled veteran exemption.
The current CAD record shows a homestead exemption.
A buyer’s future exemptions, taxable value, and tax bill 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.
This reflects the CAD net appraised value after current CAD reductions. Individual taxing units may use different taxable values when exemptions apply.
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.

6. Estimated Tax Bottom Line
The current CAD tax estimate shows exemptions reduce the estimated annual taxes by about $1,683. A buyer’s future tax bill may differ.
7. CAD Values Over Time
YOY Change reflects the change in CAD Market Value from the prior appraisal year. Taxed Value reflects the CAD net appraised value after CAD reductions in the value history. Individual taxing units may use different taxable values when exemptions apply.
| Year | Land | Impr. | Market | Taxed | YOY Change |
|---|---|---|---|---|---|
| 2021 | $91,020 | $208,160 | $299,180 | $299,180 | +$26,160 / +9.58% |
| 2022 | $155,000 | $253,040 | $408,040 | $329,098 | +$108,860 / +36.39% |

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.
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.
