Follow a Collin County Property From Growth-Grid Search to Tax and Deed Verification

Start with Collin Central Appraisal District when you need the property ID, geographic ID, appraisal owner, situs address, legal description, subdivision, market value, appraised value, taxable value, exemptions or improvement details.

Do not stop at the appraisal record. Use the Collin County Tax Assessor-Collector for the live tax statement, balance, payment and receipt, and use the County Clerk when you need a recorded deed, lien, release, plat or certified land document.

Collin CAD does not collect property taxes, and its owner field is not a deed. Collin CAD determines appraisal values, maintains appraisal records and administers exemptions and protests. The Tax Assessor-Collector handles tax statements and payments. The County Clerk maintains recorded land documents.

Start with your goal

What are you trying to complete in Collin County?

FIND A PROPERTY Search the appraisal account

Use Owner, Address, ID or Advanced Search, then confirm the property ID, legal description and map location.

Follow the official search steps
NEW HOME OR SUBDIVISION Check builder and parcel history

Fast-growing communities may show builder ownership, partial construction, new parcel IDs or incomplete-year improvements.

Review new-construction guidance
PAY PROPERTY TAX Leave CAD and open the tax ledger

Confirm the property, tax year, balance, payment fee and receipt through the county tax portal.

Use the payment workflow
FILE AN EXEMPTION Use Collin CAD forms or portal

Homestead, over-65, disability and veteran applications are appraisal-district matters, not tax-payment tasks.

Prepare an exemption filing
PROTEST A VALUE File and organise evidence

Use the notice deadline, save the record, schedule an informal review and prepare for the independent ARB.

Build the protest file
VERIFY OWNERSHIP Search recorded land documents

Use the County Clerk for deeds, liens, releases, plats and instrument history instead of relying on the CAD owner name.

Follow the land-record route

Go directly to the Collin County property task

The first sections solve the property search. Later sections cover notices, exemptions, protests, hearings, taxes, deeds and local offices.

Existing article image retained

Use the Collin CAD search tabs shown in the current article image

Collin CAD property search page showing Owner, Address, ID, ARB Search and Advanced Search tabs
Existing Collin County article image preserved in the improved guide. Portal wording and layout can change, so use the instructions below with the current official interface.
Owner tab

Begin with the last name. Try partial names, trusts, estates, LLCs or builder names when a full owner name fails.

Address tab

Start with the street number and main street name. Remove suffixes, directions, city and ZIP code when needed.

ID tab

Use a known property ID or account identifier from an appraisal notice, tax statement or saved property record.

ARB Search tab

Use protest-related fields such as protest status, hearing date or other ARB criteria when available.

Advanced Search

Narrow results with subdivision, neighborhood, geographic ID, legal description, property type, city or tax year.

Before opening a result

Do not assume the first result is correct. Compare the property ID, address, legal description and subdivision.

Portal troubleshooting

What to do when Collin CAD property search is slow or unavailable

Collin CAD currently warns that system maintenance and high traffic can temporarily delay or interrupt access to property records. The district links an alternate property search and the Texas Open Data Portal as fallback resources.
The search page will not load Wait a few minutes, refresh once, try a different browser or device and reopen the portal from CollinCAD.org.
The page loads but returns no result Simplify the owner or address search and remove optional filters that may exclude the property.
The result is outdated Note that the primary search is described as updated nightly. Contact CAD when a time-sensitive deed, split or correction is still missing.
You need bulk or downloadable data Use Collin CAD’s Open Data Portal instead of repeatedly opening individual property accounts.
Check current Collin CAD alerts Open appraisal and GIS data Open Texas Open Data
Parcel-location research

Use the Collin CAD GIS map to confirm the property and its surroundings

Open the official interactive map Open Collin CAD GIS Property Maps
Locate the account Use the property ID, address, owner or map navigation tools available in the current interface.
Compare the parcel with nearby property Check subdivision placement, road frontage, neighboring parcels and the general relationship to school or special-district areas.
Open the linked appraisal account Verify that the map parcel, property ID, legal description and appraisal page refer to the same property.
Use recorded documents for legal decisions Obtain the deed, plat, survey or title information before deciding a boundary, easement, acreage or construction issue.
The GIS boundary is not a professional survey. Do not use the appraisal map alone for fence placement, setback decisions, access rights, easements, lot-line disputes or legal acreage.
Property-account decoder

Understand what each Collin CAD field tells you

Use the appraisal field as a route to the next controlling record
Field What it identifies What it does not prove Best next action
Property ID The appraisal account used by Collin CAD. That every county database uses the same number. Save it and match it to the tax account.
Geographic ID A geographic or parcel-related identifier used in appraisal and mapping records. A surveyed legal boundary. Compare it with GIS and recorded documents.
Owner shown The owner carried in the appraisal system for administrative purposes. Complete legal title or lien status. Use County Clerk land records for ownership research.
Situs address The physical property location used in the appraisal record. The owner’s mailing address or complete legal description. Compare it with the map and deed.
Legal description The subdivision, lot, block, abstract, tract or condominium reference shown. That the abbreviated description is sufficient for a legal filing. Obtain the recorded deed, plat or survey.
Market value CAD’s opinion of market value as of January 1. A guaranteed sale price or final tax bill. Compare sales, condition and equal-appraisal evidence.
Appraised value The value after an applicable appraisal limitation. The value after every exemption. Continue to taxable value and taxing-unit lines.
Taxable value The value remaining after applicable exemptions for a taxing unit. The live amount due, penalties or payment status. Open the county tax-account lookup.
Land and improvements Land class, building area, year built, condition, use and improvement details. That every characteristic is correct. Document errors with measurements, photos or records.
Taxing units The county, city, school district and other local jurisdictions connected to the account. The final combined tax rate or bill. Use tax transparency and the tax statement.
Value explanation

Do not confuse market value, appraised value and taxable value

STEP 1 Market value

Collin CAD’s opinion of the property’s normal market value as of January 1.

STEP 2 Appraised value

The value after an applicable appraisal limitation, such as a qualifying homestead cap.

STEP 3 Taxable value

The value remaining after exemptions. It can differ by taxing jurisdiction.

Do not estimate the tax bill from market value alone. The amount depends on taxable value for each jurisdiction, adopted tax rates, exemptions, tax ceilings, credits, penalties and payment history.
Review taxing-unit rates and exemptions Open Collin tax transparency
Fast-growth property scenarios

Check new construction, builder ownership and recently created parcels carefully

Builder still shown as owner

The deed may still be processing into the appraisal system. Confirm the recorded instrument before requesting an owner update.

Improvement is partly complete

Review the completion percentage, building area and January 1 condition rather than comparing only the total value.

New address returns nothing

Search the builder, subdivision, street name, parent parcel, property ID or geographic ID.

Parcel split or replat

New land records may not appear immediately. Search the parent account and review the recorded plat or replat.

Similar subdivision names

Confirm the city, phase, lot, block, neighborhood and school district before relying on a result.

Special taxing districts

Review every jurisdiction on the account. Newer developments may include municipal utility or other special districts.

Condominium or townhome

Match the unit number, legal description, property ID and geographic ID rather than using the shared street address alone.

Recent purchase price

Save the closing disclosure, contract, inspection, repair estimates and photographs when the purchase condition supports a lower value.

Future tax estimate

The seller’s cap, exemptions and ceiling may not transfer. Recalculate using the buyer’s likely taxable value and exemptions.

2026 appraisal notice

Read every part of the Collin County Notice of Appraised Value

Collin CAD states that 2026 real-property Notices of Appraised Value were scheduled to be mailed on April 15. The first batch of business personal property notices was scheduled for May 13, with additional notices continuing into early June.
Owner and account

Confirm the owner, property ID, address, legal description and mailing address.

Proposed values

Compare prior and current market and appraised values, including land and improvement components.

Property characteristics

Check use, class, area, year built, condition and other details that can affect valuation.

Exemptions

Verify every expected homestead, age, disability, veteran or special-use benefit.

Protest deadline

Use the exact deadline printed on the notice rather than relying only on a general calendar.

Owner ID and eFile PIN

Protect these credentials. They can be used to enrol the property in the taxpayer portal.

An appraisal notice is not the property-tax bill. Taxing units adopt rates later, and the Tax Assessor-Collector issues the tax statement.
Online account access

Use the Collin CAD taxpayer portal for documents and protests—not tax payment

Open the official taxpayer portal Open Collin CAD Taxpayer Portal
Create a user account Use a current email address and follow the registration steps.
Add the property with its Owner ID and eFile PIN These credentials appear on the most recent appraisal or exemption notice.
Do not use the previous owner’s PIN Collin CAD states that owner PINs are unique. A buyer should use credentials issued for the current owner.
Review documents and communication choices Use the portal for available property details, notices, electronic communication and appraisal-protest services.
Use the county tax portal to pay The taxpayer portal specifically states that it cannot accept property-tax payments.
Keep the eFile PIN private. Collin CAD describes the PIN as a digital signature. Do not post it publicly or share it with an unauthorised person.
Office routing

Use Collin CAD, the Tax Office or County Clerk for the correct task

Send the request to the office that controls the record
Your question Correct starting point What to prepare
Why did my value change? Collin Central Appraisal District Property ID, notice, tax year and supporting value evidence.
Why is an exemption missing? Collin Central Appraisal District Application proof, identification and qualification date.

Record corrections

Correct the database that actually contains the error

Incorrect appraisal owner Confirm the recorded deed or probate document, save the instrument number and provide Collin CAD with the documentation it requests.
Incorrect mailing address Update the appraisal-district mailing record and complete the Tax Office address-correction process when the tax bill is also wrong.
Incorrect property address Determine whether the situs issue belongs to CAD, the city, emergency addressing or another authority.
Wrong building area or condition Save the account and prepare measurements, photos, plans, permits, appraisals or repair estimates.
Missing exemption Confirm the application, filing date, identification, occupancy and supporting documents.
Incorrect tax payment or balance Contact the Tax Office with the receipt, property account, year, amount and confirmation number.
A correction request does not automatically protect a protest deadline. File a timely protest when the issue is protestable and unresolved before the date on the appraisal notice.
Exemption filing

Apply for Collin County homestead and related exemptions without paying a filing service

Collin County and Collin CAD state that there is no fee to apply for an exemption through the appraisal district. Be cautious with private mailers or websites that charge for a form available from the official district.
Residence homestead

The property generally must be owned and occupied as the individual owner’s principal residence.

Age 65 or older

Review the additional exemption, school-tax ceiling and any available instalment or deferral provisions.

Disabled person

Prepare the required disability evidence and review possible ceiling or payment protections.

Disabled veteran

Use the application matching the disability rating, residence status and surviving-spouse situation.

Surviving spouse

Review the age, disability or veteran exemption continuation rules for the specific situation.

Agricultural or special use

Prepare use history, acreage, leases, production evidence and other documentation requested by Collin CAD.

Bring all evidence to the informal review Appraisers can make value decisions during the meeting, so do not arrive with only a verbal complaint.
Review the district evidence Compare sales, property characteristics, model information and the district’s position with the actual property.
Prepare for the formal ARB hearing Organise the strongest point first and label each photograph, comparable, estimate and supporting document.
Preserve the written order Review any binding-arbitration, court or other appeal deadline immediately after receiving the ARB decision.
Evidence recommended by Collin CAD for informal review
Property type Useful information How to organise it
Residential real property Closing disclosure, contracts, comparable sales, appraisals, loan documents, repair estimates and photographs. Create a one-page requested-value summary with numbered exhibits.
Commercial real property Rent rolls, leases, income and expense statements, construction documents and market information. Separate income, expenses, occupancy, condition and market evidence.
Business personal property Depreciation schedules, balance sheets, IRS returns and CPA statements concerning inventory or equipment. Tie every requested adjustment to an asset category.
Telephone appraisal inquiries are not the same as an in-person informal review. Collin CAD states that telephone inquiries are typically answered by mail within approximately 15 business days.
Focused protest statement
I am protesting property ID [number] for tax year [year] because [specific value or property-record issue]. The current account shows [current information]. My evidence shows [correct information]. I am requesting [specific value or correction].

Formal protest hearing

Prepare for the independent Collin Appraisal Review Board

The Collin ARB is separate from Collin CAD. It resolves taxpayer protests, taxing-unit challenges and disputes involving exemptions or agricultural appraisal for the tax year under review.
Key Collin ARB hearing preparation rules
Hearing item Published guidance Practical next step
Hearing notice The ARB sends hearing notification at least 15 days before the hearing. Check the date, time, participation method and submission instructions immediately.
Telephone or video request The owner must generally request remote participation in writing no later than the tenth day before the hearing. Include the owner name, address and property account number.
Remote-hearing evidence Evidence must be offered by affidavit or written declaration and received before the hearing. Use the ARB form and submit evidence early.
Requested evidence timing The ARB requests affidavits, declarations and evidence approximately three days before the hearing. Do not wait until the hearing morning to upload or send files.

Read Collin ARB hearing steps Open ARB forms Review binding arbitration
Bills, payments and receipts

Move from the Collin CAD appraisal account to the county tax ledger

The appraisal account explains value and exemptions but does not show the controlling payment ledger. Property-tax statements are generally mailed in October and are due upon receipt.

Open the official tax-account lookup Open Collin County Search and Pay Property Tax
Search the strongest account detail Use the tax-account number when available. Otherwise search with the owner or property information supported by the current portal.
Match the tax record to Collin CAD Compare the property address, account, owner, legal description and tax year before paying.
Review all years and balances Check current and delinquent amounts, penalties, interest, partial payments and refund information.
Read the payment fee Confirm the current service or convenience fee at checkout before authorising payment.
Save the receipt Keep the account, tax year, amount, fee, payment date, confirmation number and payment method.
Reopen the account after processing Verify that the payment posted to the correct property and tax year.
No tax statement by November 1? The county directs property owners to use the Tax Account Lookup or contact the Property Tax Department at 972-547-5020.
Use the property-tax payment page, not a motor-vehicle payment page. Card fees and processing rules can differ by county service. Treat the fee shown in the property-tax checkout as controlling.
Search and pay property taxes Read property-tax guidance Open tax forms and payment-plan form
Recorded land documents

Use the Collin County Clerk for deeds, liens, plats and instrument history

The County Clerk advises users who know only the physical property address to find the property details through Collin CAD first, then search recorded documents by name, instrument number or volume and page.
Open the official Land Recordings page Open Collin County Land Recordings
Continue to the county deed search Search by grantor or grantee name, instrument number, or volume and page.
Use the correct instrument-number format Records from January 2006 through April 2022 generally use a 17-digit number with a trailing zero. Records beginning May 2, 2022 generally use a 13-digit number.
Match the recorded document Compare parties, recording date, legal description, subdivision, acreage and instrument number with the CAD account.
Order the required copy Determine whether a plain copy, certified copy or official records request is needed.
Use a title professional for title conclusions The online database may contain redactions and does not replace the official repository or a complete title examination.
Selected Collin County land-recording fees published at the time of review
Service Published fee Practical note
Standard land-record document $25 first page and $4 each additional page Confirm non-standard, indexing and document-specific fees before filing.
Name, legal or document-type search $10 Online self-search may avoid an unnecessary paid staff search.
Document copies $1 per page Confirm the page count before ordering.
Certified copy $1 per page plus $5 certification Use certification only when required by the receiving party.
New deed not showing online? The County Clerk states that newly recorded documents may take approximately 7–10 business days to appear on public search stations.
Buyer and new-owner checks

Complete these checks before buying or relying on a Collin County property record

Confirm parcel identity

Match the property ID, geographic ID, legal description, unit, subdivision and map location.

Check tax status

Review current and delinquent years, payment history, refunds and the correct tax account.

Search recorded documents

Review deeds, liens, releases and plats. Use a title company for a complete title examination.

Recalculate exemptions

The seller’s homestead, age, disability, veteran or tax-ceiling benefit may not transfer.

Review taxing units

Check city, county, school, utility and special-district jurisdictions associated with the parcel.

Compare property facts

Review building area, use, year built, class, condition and completion against the actual property.

Check builder history

Determine whether the current account still reflects builder ownership or partial construction.

Review future tax exposure

Estimate taxes without assuming the seller’s appraisal limitation or exemptions will continue.

Save closing evidence

Keep the deed, title policy, survey, closing disclosure, tax certificate and exemption confirmation.

The current tax statement may understate the buyer’s future bill. A sale can change exemptions, appraisal limitations, tax ceilings and the owner information used in future appraisal years.
Public information

Use Collin CAD open data before filing a custom records request

Individual property account

Use Property Search for one owner, parcel, value or exemption record.

GIS and appraisal exports

Use the Open Data Portal for downloadable appraisal files and GIS shapefiles.

Appraisal reports

Review annual reports, certified totals, value summaries, mass-appraisal reports and taxpayer reports.

Existing government record

Use an open-records request when the identifiable record is not already published online.

ARB evidence

Request the appraisal-district information required for a protest through the applicable protest-evidence process.

Recorded deed or lien

Use the County Clerk rather than a Collin CAD open-records request.

An open-records request must seek existing records. Collin CAD is not required to create new records, perform legal research or answer a list of general questions.
Collin CAD states that confidential sales information is generally not public under the ordinary open-records process, but applicable appraisal evidence must be disclosed for ARB hearings under the property-tax protest rules.

Collin County answers

Accuracy, ownership and official-use notice

AppraisalDistrict.org is an independent informational resource. It is not Collin Central Appraisal District, the Collin Appraisal Review Board, Collin County, the Tax Assessor-Collector, the County Clerk, the Texas Comptroller, a surveyor or a title company.

Property owners, appraisal values, exemptions, property characteristics, protest status, tax balances, payment fees, office hours, forms and deadlines can change. Verify the live official record before paying, filing, travelling, buying, selling or making a legal or financial decision.

Appraisal maps, acreage and abbreviated legal descriptions are research resources and should not replace a recorded deed, plat, title examination or professional survey.
