Property Taxes in Plano
Property taxes are a genuine, ongoing cost for Plano homeowners, and the effective rate carries some real disagreement depending on what's being measured: a Collin County-wide effective rate around 1.58% is commonly cited, while the more directly Plano-specific combined rate across Plano ISD, the City of Plano, Collin County, and Collin College runs closer to 1.71%. What's not in dispute: the state's homestead exemption and appraisal cap were both meaningfully expanded for 2026, applying here exactly as they do statewide.

Learn moreFour Overlapping Taxing Entities -- Simpler Than Houston's Seven-Plus
A typical Plano homeowner pays property tax into four layers: Plano ISD (the school district), the City of Plano, Collin County, and Collin College -- a meaningfully simpler stack than the seven-plus overlapping entities a typical Harris County homeowner pays into (school district, city, county, hospital district, flood control district, port authority, and county department of education). Each entity sets its own rate annually; the combined total, not any single entity's rate, is what determines the actual bill.
Effective Rate: A Real Disagreement Depending on What's Measured
Sources reviewed this session cited genuinely different figures depending on methodology: a Collin County-wide effective rate around 1.58% (Ownwell-style synthesis), while a separate source describing the "typical Plano homeowner" cited a combined rate closer to 1.71% across Plano ISD, city, county, and Collin College. A third source cited notably lower, ZIP-specific effective rates -- 1.22% for ZIP 75024 and 1.14% for ZIP 75025 -- that appear to reflect exemption-adjusted effective rates on specific, likely higher-value properties rather than a nominal combined rate; this discrepancy is disclosed rather than resolved. Confirm your specific parcel's current combined rate against the Collin Central Appraisal District directly rather than relying on any single aggregated figure, including this range.
Homestead Exemption: Meaningfully Larger for 2026 (Statewide Fact)
The mandatory school-district homestead exemption jumped from $100,000 to $140,000 for the 2026 tax year, following Proposition 13, approved by Texas voters in November 2025 -- a real, recent, statewide increase that applies in Plano ISD exactly as it does everywhere else in Texas. Homeowners 65 or older or disabled receive an additional $60,000 on top of that, for up to $200,000 total exempted from school-district taxes. This exemption applies only to school-district levies specifically; it does not reduce the city, county, or Collin College portions of the bill the same way.
Texas's 10% Appraisal Cap
Once a homestead exemption is on file with the county appraisal district, Texas Tax Code §23.23 caps how fast the assessed (taxable) value of that home can rise year to year at 10% maximum, regardless of how much the market value actually moves. This is a real protection against a sudden appraisal spike, and it applies in Collin County exactly as it does statewide -- a homeowner in a fast-appreciating Plano-area neighborhood can still see meaningful, compounding assessed-value growth year over year, but not an uncapped one.
No MUD Tax Layer for Most of Plano
Because most of Plano is served directly by City of Plano utilities rather than a Municipal Utility District (see the moving topic page), most Plano homeowners don't carry the additional MUD tax layer that's common in newer, still-developing suburban Houston-area or outer-DFW developments. Confirm this for a specific address regardless, since utility districts and city boundaries don't always align exactly, especially near the city's edges.
Key takeaways
- Plano homeowners typically pay into four overlapping taxing entities (Plano ISD, City of Plano, Collin County, Collin College) -- simpler than Harris County's seven-plus.
- Sources disagreed on the effective rate this session, likely reflecting different methodologies: a Collin County-wide figure around 1.58%, a Plano-specific combined rate closer to 1.71%, and notably lower ZIP-specific figures (1.14%-1.22%) that appear to reflect exemption-adjusted rates on specific properties -- confirm your parcel's rate with the Collin Central Appraisal District.
- The school-district homestead exemption rose from $100,000 to $140,000 for 2026 (Proposition 13, approved November 2025), a statewide change that applies fully in Plano ISD; homeowners 65+ or disabled get an additional $60,000 (up to $200,000 total).
- Texas's 10% annual appraisal cap (for homesteaded properties) applies here exactly as it does statewide -- real protection, but it still allows meaningful year-over-year assessed-value growth.
- Most of Plano is served directly by city utilities rather than a MUD, so most homeowners don't carry the additional MUD tax layer common in some newer DFW-area and suburban Houston developments -- confirm for a specific address.
