Collin Property Tax: Collin CAD Rates & Appeals (2026)

For 2026 Collin homeowners, the regular real-property protest deadline was midnight on May 15, 2026; if your Notice of Appraised Value was postmarked after April 16, your notice may have shown a later deadline under the 30-day rule. File with the Collin Appraisal Review Board through the Collin CAD Taxpayer Online Portal, or by mail/hand delivery using PROPERTY APPRAISAL – NOTICE OF PROTEST – Tax Year 2026, CCAD-132 at 250 Eldorado Pkwy, McKinney, TX 75069. As of July 30, 2026, the regular 2026 deadline has passed; the next regular real-property deadline is expected to be May 17, 2027 because May 15, 2027 falls on a Saturday, unless your 2027 notice gives a later date.

How assessments work in Collin

Collin Central Appraisal District, usually searched as Collin CAD or CCAD, appraises property for Collin County’s taxing units; the tax office later bills and collects the tax, but CCAD sets the appraised values and administers exemptions. CCAD says it values property at market value as of January 1 each year, sends Notices of Appraised Value around April 15, and includes the prior certified value, proposed current value, exemptions/special valuations, and the protest deadline on the notice. (collincad.org)

The 2026 cycle is unusually concrete because CCAD’s 2025-2026 reappraisal plan publishes dates: January 1, 2026 was the appraisal date; real-estate notices were mailed April 15; informal meetings began April 15; the real-estate protest deadline for notices dated April 15 was May 15; the chief appraiser submitted real-estate records to the ARB May 22; and all ARB panels were scheduled to hear 2026 protests May 22 through July 10. (collincad.org)

For houses, expect a mass-appraisal model, not a private appraisal of your home. CCAD describes using property characteristics, permits, maps, sales, listings, field inspections, cost data, and comparable sales; the three approaches are cost, direct sales, and income, with the sales-comparison approach especially important for improved residential property. (collincad.org)

Whether you should appeal

Appeal if you can prove either market value is too high or your home is not appraised equally and uniformly compared with similar Collin homes. The best Collin-specific evidence is: a closing statement or appraisal near January 1, 2026; photos and repair bids for condition problems CCAD could not see; incorrect square footage, class, pool, garage, or remodel data; and nearby comparable sales or appraisal records from the same subdivision, school district, or market area. The ARB’s own FAQ advises using sales closest to January 1 and comparable homes similar in size, age, location, and construction. (collinarb.org)

Do not appeal just because the tax bill feels high. Texas taxing units set rates later; the ARB decides the appraised value, exemptions, and special-appraisal issues. Also check whether your homestead cap is doing the work: once the homestead limitation applies, your taxable appraised value generally cannot rise more than 10% per year plus new improvements, so reducing a market value that is still above the capped appraised value may not reduce this year’s tax. (collincad.org)

Collin does publish protest volume, but I did not find an official Collin source publishing homeowner success rates or median reductions. In an August 2025 CCAD board packet, the district reported 137,147 total 2025 protests, including 20,074 taxpayer protests and 117,073 agent protests, plus 45,236 total hearings; useful workload context, but not a win-rate. (collincad.org)

Step-by-step how to file

1. Find the deadline on your notice. For most 2026 real property with an April 15 notice date, it was May 15, 2026 at midnight. Statewide, the usual rule is May 15 or 30 days after the notice is mailed, whichever is later; Collin’s 2026 form says a different deadline may apply if the notice was postmarked after April 16. (collincad.org)

2. Use the official protest form or a written protest. The form name is PROPERTY APPRAISAL – NOTICE OF PROTEST – Tax Year 2026, CCAD-132. CCAD also says an official form is not strictly required if your written protest identifies the owner, the property, and the reasons for protest; first-time homeowners should still use CCAD-132 because it prompts the right boxes. (collincad.org)

3. Choose every reason that fits. For a house, the common boxes are Market & Equity - Incorrect appraised (market) value and value is unequal compared with other properties, or just Market - Incorrect appraised (market) value. If you are fighting a denied homestead, over-65, disabled-person, disabled-veteran, ag-use, or other special appraisal issue, check that issue too; do not leave it off and try to add it later. (collincad.org)

4. File by an accepted method. CCAD’s 2026 protest form says protests must be filed using the Online Appeals eFile website, by mail, or in person. The online Taxpayer Portal requires the Owner ID and eFile PIN from your mailed appraisal or exemption notice; CCAD warns not to use a prior owner’s PIN. If you are within four days of the deadline and need a PIN, CCAD recommends mail or in-person filing rather than waiting. (collincad.org)

5. Use the correct address. Mail or hand-deliver to Collin Central Appraisal District / Collin Appraisal Review Board, 250 Eldorado Pkwy, McKinney, TX 75069. CCAD business hours are generally Monday-Friday, 8:00 a.m. to 4:00 p.m.; the ARB FAQ says the doors lock promptly at 4:00 p.m. for in-person deadline filings. (collincad.org)

6. Do not rely on email for the initial protest. The 2026 CCAD-132 filing methods list portal, mail, and in-person—not email. Email is used later for hearing evidence, video/phone requests, rescheduling, and withdrawals; for example, ARB hearing evidence may be sent to CollinARB@CollinARB.org, and reschedule/withdrawal requests use reschedule@cadcollin.org. (collinarb.org)

7. Fee. CCAD’s protest form does not require a filing fee for the ARB protest. Costs can arise only if you continue after the ARB order, such as binding arbitration or court appeal.

What happens after

The appeal authority is the Collin Appraisal Review Board, a separate citizen board from CCAD. The ARB resolves disputes between taxpayers and the appraisal district and its decisions are binding only for that tax year. (collinarb.org)

After a timely protest, the ARB assigns a case number and schedules a hearing. Collin’s ARB must send your hearing notice at least 15 days before the hearing; at least 14 days before the hearing, the appraisal district must send taxpayer-remedies materials, procedures, postponement information, and information about inspecting the district’s evidence. (collinarb.org)

Collin hearings can be in person, by sworn affidavit or written declaration without appearing, or by telephone/video conference if requested. For phone or video, notify the ARB in writing no later than the 10th day before the hearing and submit evidence by affidavit or written declaration before the hearing; the ARB requests evidence three days early for processing. (collinarb.org)

A normal Collin panel hearing is practical and short: check in no earlier than 30 minutes before your time; the district appraiser and recorder are in the room; proceedings are audio-recorded; witnesses are sworn; each side presents evidence; and the panel discusses the evidence and renders a decision. Collin says protests are typically heard by three-member panels, unless a single-member panel is requested, with as many as 15 panels running concurrently. (collinarb.org)

After the hearing, the ARB sends a written final order by certified mail with appeal information. There is no further appeal to the ARB; the next level is generally district court, regular binding arbitration, SOAH for certain properties, or limited binding arbitration for specific procedural violations. (collinarb.org)

Local tips

First, check exemptions before you spend hours on comparable sales. Collin County’s official 2025 tax-rate/exemption summary lists the county rate as 0.149343 per $100, a county homestead exemption of 5% / $5,000 minimum, an over-65 exemption of $30,000, and a disability exemption of $20,000. The same summary shows many school districts with a $140,000 homestead exemption and Collin College with a 20% homestead exemption and $100,000 over-65/disability exemptions. (collincountytx.gov)

Second, file the homestead exemption if you missed it. CCAD says the general homestead application should be filed between January 1 and April 30, but a late homestead application can be filed up to two years after the taxes became delinquent for that year; the county tax office also says there is no fee to file the homestead exemption form. (collincad.org)

Third, use Collin’s evidence rules. Upload evidence through the portal if possible. If not, Collin accepts printed evidence on 8.5-by-11 paper; electronic evidence should be PDF when possible, and accepted file types include Word, Excel, PowerPoint, BMP, JPG/JPEG, PNG, and TIFF—not HEIC/HEIF. (collinarb.org)

Worked savings example. Suppose a McKinney homeowner in McKinney ISD persuades the ARB to reduce taxable value by $25,000. Using the latest official posted rates in the Collin tax-rate summary—Collin County 0.149343, McKinney City 0.412284, McKinney ISD 1.104300, and Collin College 0.081220—the combined rate is 1.747147 per $100. Estimated annual savings: $25,000 ÷ 100 × 1.747147 = $436.79. County tax alone would save only $37.34; your real bill depends on your city, school district, college, MUD, PID, and exemptions. (collincountytx.gov)

Finally, remember payment timing. Collin County tax statements are mailed in October and are due on receipt; to avoid penalty and interest on the current bill, pay by January 31, 2026 for the 2025 tax statement cycle. Appealing your value does not eliminate the need to pay taxes that become due. (collincountytx.gov)

Collin Property Tax Rate

Collin County taxing unit 2025 adopted total property tax rate: $0.149343 per $100 of assessed value (0.149343%). This is only the county taxing unit rate; a homeowner’s total rate also depends on city, school district, college, and any special districts for the parcel.

When Are Property Taxes Due in Collin?

Property tax statements are mailed in October and are due upon receipt; to avoid penalties, pay by January 31, 2026. The county FAQ also states taxes are delinquent on February 1 each year and payments must be postmarked before the delinquency date. Partial payments are allowed, but any unpaid balance after January 31 accrues penalty and interest. Taxpayers with an Over-65 or Disabled Person exemption on their homestead residence may pay current taxes in four installments without penalty or interest: 1/4 by January 31, 1/4 by March 31, 1/4 by May 31, and 1/4 by July 31; if an installment is missed, the full penalty accrues.

This is not the same as the assessment appeal deadline above. The appeal deadline is your window to contest your assessed value; the payment due date is when the resulting tax bill must be paid. Missing one does not affect the other, but missing either has real consequences — one forfeits your right to appeal for the year, the other can trigger penalties and interest.
