Collin County Property Records, Appraisals and Tax Help
Search a Collin County home, new-construction property, acreage tract, commercial building or business account by owner, property address, account number or appraisal-district identifier.
This guide explains how to read the certified 2026 record, use the interactive parcel map, verify exemptions, understand taxing jurisdictions, check tax balances, find recorded deeds and determine whether a post-deadline appraisal remedy may still apply.
Start With the Collin County Service You Need
Appraised value, tax balances, deeds, exemptions and parcel maps are handled through different portals. Use the task cards below rather than submitting the same question to several offices.

View the parcel map
Locate an appraisal parcel and compare mapped streets, subdivisions and surrounding account information.
Open interactive map →Manage notices or appeals
Register using the Owner ID and eFile PIN printed on an appraisal or exemption notice.

Search official records →How to Search Collin CAD Property Records
The main Collin CAD search is intended for public property research. Search with the smallest reliable piece of information, inspect the matches and then open the correct account.
Owner-name search
Best for finding several accounts owned by one person, trust or company. Try the last name or main business word before entering the complete legal name.
Property-address search
Best for houses, apartments and commercial sites with a recognized physical address. Do not confuse the situs address with the owner’s mailing address.
Account-number search
Best for appraisal notices, exemption applications, correction requests, open-record requests and repeat research.
No-result search
Try the prior owner, a shorter street name, subdivision, map search or County Clerk record if the deed was recorded recently.
How to Read a Collin County Appraisal Record
| Record field | What it means | What to verify |
|---|---|---|
| Account or property ID | Collin CAD’s unique identifier for the appraisal account. | Use it when contacting the CAD, submitting forms or matching the tax record. |
| Owner ID | An identifier connected with the owner record. | The taxpayer portal may request this ID with the eFile PIN from a mailed notice. |
| Owner and mailing address | The ownership and correspondence information carried by the CAD. | Compare ownership with the recorded deed and keep the mailing address current. |
| Property address | The physical or situs location assigned to the property. | It can differ from the owner’s mailing address. |
| Legal description | An abbreviated lot, block, subdivision, survey or tract description. | Verify it against the recorded deed and plat before using it for legal purposes. |
| Market value | The district’s opinion of market value as of January 1 for the appraisal year. | Check the selected year, land, improvements, condition and property classification. |
| Appraised value | The value after applicable appraisal limitations or special appraisal treatment. | It may differ from market value because of a homestead cap or other limitation. |
| Taxable value | The value remaining for a particular taxing unit after exemptions. | Different entities can show different taxable values. |
| Land value | The appraised component assigned to the lot or acreage. | Review land size, location, use, frontage and neighborhood assignment. |
| Improvement value | The value assigned to houses, buildings and other improvements. | Check square footage, year built, construction class, quality and condition. |
| Exemption codes | Approved homestead, age-65, disability, veteran or other exemption information. | A missing exemption can indicate no application, pending review, denial or account mismatch. |
| Taxing entities | The county, city, school, college, MUD and other districts connected to the account. | Confirm city, school and special-district assignments carefully. |
| Deed history | Appraisal-system references to ownership or transfer activity. | Use the County Clerk’s recorded document for legal verification. |
How to Use the Collin CAD Interactive Map
The GIS map helps identify an appraisal parcel and its relationship to roads, subdivisions and nearby accounts. It is not a boundary survey, zoning certificate or title report.
Collin County Search Tips by Property Location
Collin County includes dense established neighborhoods, fast-growing subdivisions, rural acreage and properties with municipal utility or special-district accounts. The best search method changes with the property.
New-construction check
- Confirm the January 1 completion status.
- Review living area and improvement class.
- Check whether unfinished areas were included.
- Save dated construction photographs.
- Compare the deed and closing date.
MUD or special-district check
- Read every taxing entity on the account.
- Do not assume the city provides every service.
- Check the entity’s tax rate separately.
- Review homestead exemptions by entity.
- Compare the tax statement with the CAD list.
Recently purchased property
- Verify deed recording with the County Clerk.
- Allow time for the CAD owner update.
- Update the mailing address.
- Apply for homestead when eligible.
- Review notices sent to the prior owner.
What 2026 Certified Status Means for Property Owners
Collin CAD’s 2025–2026 reappraisal calendar scheduled appraisal-roll certification for July 25, 2026. The official search now identifies 2026 as certified, and the district has posted a certified value summary and totals.
What certification does
- Finalizes most appraisal records for the tax cycle.
- Allows values to be delivered to taxing units.
- Supports rate and tax-statement calculations.
- Changes the remedy from an ordinary timely protest to narrower statutory procedures.
What certification does not do
- It does not make a CAD record a legal title document.
- It does not prevent ownership or mailing-address updates.
- It does not eliminate all late exemption provisions.
- It does not eliminate qualifying correction motions or supplemental appraisal activity.

Filter, sort, query and export current appraisal information through the linked Texas Open Data Portal.
Open data resources →GIS parcel data

Search grantor, grantee, subdivision, document type, instrument number or plat records through the County Clerk.
Open official record search →| Research goal | Best official source | Important limitation |

| Many appraisal accounts | Open Data Portal | CCAD does not provide technical support for user-created data analysis. |
| Parcel features and GIS data | Interactive map or ArcGIS hub | Mapped lines are not legal surveys. |
| Deed, lien, release or plat | County Clerk official records | The Clerk records documents but does not provide title opinions. |

Collin County Property-Tax Dates to Watch
How to Read Collin County Tax Rates and Exemptions
Collin CAD maintains a searchable table containing entity type, entity code, entity name, exemptions, homestead amounts, age-65 and disability relief, freeze information and maintenance, operations, debt and total tax rates.
City and county entities
Check whether the account is inside an incorporated city and whether the listed county entities match the property’s location.
School district
Verify the assigned ISD and the school homestead, age-65, disability and tax-ceiling information.
MUD and special districts
Newer developments can include municipal utility, water-control, emergency-service or other special taxing districts.
Basic entity-tax estimate
Taxable value ÷ 100 × adopted tax rate = estimated tax for that entity.
Calculate each entity separately using the taxable value shown for that entity. Do not add every rate in the county database because only entities listed on the property account apply.
What to Verify Before and After a Collin County Sale
Before buying
- Match the CAD account to the deed description.
- Check improvement size and completion status.
- Review city, school and special districts.
- Check current and delinquent tax balances.
- Do not assume the seller’s exemptions transfer.
After closing
- Confirm the deed was recorded.
- Allow processing time for the CAD owner update.
- Update the mailing address.
- Apply for homestead when eligible.
- Review notices sent under the previous owner.
New construction
- Check the January 1 completion percentage.
- Compare plans with CAD square footage.
- Document unfinished areas.
- Confirm lot and improvement accounts.
- Check MUD and special-district taxation.
Fix Common Collin CAD Search and Filing Problems
| Problem | Likely reason | Best next step |
|---|---|---|
| No owner-name result | Different spelling, trust, estate, company, prior owner or last-name-first format. | Search the last name alone, remove punctuation and try the property address. |
| No address result | New street, abbreviated suffix, separate unit, incomplete situs address or construction account. | Use the property ID, subdivision, prior address or interactive map. |
| New owner not displayed | The deed was recorded recently or has not completed CAD processing. | Verify the instrument in County Clerk records and contact the CAD if the delay continues. |
| 2026 protest link does not allow filing | The ordinary filing deadline has passed or the account lacks portal eligibility. | Contact Collin CAD and identify the legal basis for a late protest or correction. |
| Taxpayer portal will not register | Wrong Owner ID, wrong eFile PIN, expired notice information or email-verification issue. | Copy the information from the latest mailed notice and use the district help resources. |
| Homestead exemption is missing | No application, pending review, missing documentation, denial or wrong account. | Check the online form status and contact Collin CAD with the submission confirmation. |
| CAD and tax account numbers differ | The appraisal and collection systems can use different identifiers. | Match owner, property address, legal description and appraisal-district number. |
| Wrong MUD or city appears | Jurisdiction coding, annexation, boundary or account-update issue. | Save the CAD account and provide jurisdiction evidence to the appropriate office. |
| Payment not posted | Processor delay, rejected payment or payment applied to another account. | Keep the receipt and contact the County Tax Office. |
| Map boundary appears wrong | GIS lag, parcel split, mapping issue or nonsurvey representation. | Compare the deed, plat and survey before requesting a mapping correction. |
