Collin County property tax rates for 2026, city by city
Collin County's tax office lists every 2026 rate in one table (Collin County Tax Assessor-Collector). Among the nine covered cities in it, McKinney has the lowest city rate and Wylie the highest, but the city rate is only part of the story: Plano and Frisco take 20% off a homestead's value before the rate applies, and McKinney, Celina and Wylie take nothing (Collin County Tax Assessor-Collector). In every example below, the school district line is the largest.
The 2026 rates, per $100 of taxable value
City rates, lowest to highest: McKinney $0.412284, Allen $0.414700, Frisco $0.425517, Plano $0.437600, Melissa $0.454116, Prosper $0.505000, Anna $0.548282, Celina $0.571677 and Wylie $0.596554 (Collin County Tax Assessor-Collector). Collin County's own rate is $0.151414, and Collin College's is $0.081220 (Collin County Tax Assessor-Collector).
School district rates, lowest to highest: Frisco ISD $1.019400, Plano ISD $1.032750, McKinney ISD $1.066400, Allen ISD $1.103700, Wylie ISD $1.175200, Melissa ISD $1.200800, Prosper ISD $1.201100, Celina ISD $1.208800 and Anna ISD $1.215800 (Collin County Tax Assessor-Collector). A district's name is not a city limit: the district on your bill depends on your address, so check it before you compare.
Homestead exemptions differ more than the rates
State law requires every school district to exempt $140,000 of a residence homestead's value, and lets any taxing unit add its own exemption of up to 20% of appraised value, at least $5,000 (Texas Comptroller). All nine school districts above list the $140,000 (Collin County Tax Assessor-Collector). The cities choose differently: Plano and Frisco exempt 20%, Prosper 17.5%, Melissa 6%, Allen 5% and Anna 3%, while McKinney, Celina and Wylie list no general homestead exemption (Collin County Tax Assessor-Collector). Collin County exempts 5% and Collin College 20% (Collin County Tax Assessor-Collector).
What that means on a $500,000 homestead
Applying each listed rate and exemption to a homestead appraised at $500,000, the city line comes to about $1,702 in Frisco, $1,750 in Plano, $1,970 in Allen, $2,061 in McKinney, $2,083 in Prosper, $2,134 in Melissa, $2,659 in Anna, $2,858 in Celina and $2,983 in Wylie (our arithmetic on (Collin County Tax Assessor-Collector)). McKinney has the lowest rate, but Frisco's and Plano's 20% exemptions give them the lower city bills. Collin County adds about $719 and Collin College about $325.
The school line, after the $140,000 exemption, is about $3,670 in Frisco ISD, $3,718 in Plano ISD, $3,839 in McKinney ISD, $3,973 in Allen ISD, $4,231 in Wylie ISD, $4,323 in Melissa ISD, $4,324 in Prosper ISD, $4,352 in Celina ISD and $4,377 in Anna ISD (our arithmetic on (Collin County Tax Assessor-Collector)). These are illustrations, not bills: they leave out special districts, other exemptions and any limit on a homestead's appraised value.
Owners 65 and older
School districts must give owners who are 65 or older or disabled an extra $60,000 homestead exemption (Texas Comptroller), and the table shows that for all nine districts (Collin County Tax Assessor-Collector). The cities' extra exemptions for owners 65 and older range widely: $90,000 in McKinney, $80,000 in Frisco, $50,000 in Allen, $40,000 in Plano, $30,000 in Anna, Celina, Melissa and Wylie, and $10,000 in Prosper (Collin County Tax Assessor-Collector). Plano, Prosper and Wylie (2004), Celina (2018), Frisco (2022) and Melissa (2025) are listed with the optional tax freeze, as are Collin County and Collin College (2004) (Collin County Tax Assessor-Collector). Under Texas Tax Code 11.261, a county, city or junior college district that adopts it may not raise the total tax on a qualifying 65-or-older or disabled owner's homestead above the first year's amount, except for new improvements (Texas Tax Code Section 11.261 (Texas Public Law)).
What the table leaves out
Some neighborhoods also pay a special district: the same county table lists more than 30 special districts, including municipal management and utility districts, each with its own rate, such as Celina MMD #2 at $0.770000 and Rainwater Crossing MMD at $0.800000 (Collin County Tax Assessor-Collector). Where part of a city lies in another county, that part is taxed on the other county's list, not this one.

Which covered Collin County city has the lowest 2026 city tax rate?
McKinney, at $0.412284 per $100 (Collin County Tax Assessor-Collector). On a $500,000 homestead, though, Frisco and Plano come out lower on the city line (about $1,702 and $1,750 against McKinney's $2,061), because both exempt 20% of a homestead's value and McKinney lists no general homestead exemption (Collin County Tax Assessor-Collector).
Do all Collin County school districts give the same homestead exemption?
Yes for the general exemption: state law sets it at $140,000 for every school district, plus $60,000 more for owners 65 or older or disabled (Texas Comptroller), and the county table shows those amounts for the districts listed here (Collin County Tax Assessor-Collector). What differs from district to district is the tax rate.
