Taxes in Southlake
Texas's no-state-income-tax status applies fully in Southlake, and the city's combined sales tax rate sits at 8.25% -- the same statutory maximum already established for Dallas and Denton in this build (6.25% state, 1.75% city, 0.25% special district, per Avalara data reviewed August 2026). Property tax is where the real weight lands for a Southlake household, and given the city's median home value, that weight is large in dollar terms even where the underlying rate itself is unremarkable for the region.

Learn moreNo State Income Tax (Statewide, Not Southlake-Specific)
Texas is one of a small number of states with no state personal income tax, a structural fact that applies statewide, including in Southlake. Given the city's high median household income (cited around $250,001, per Point2Homes data reviewed August 2026), this is a genuinely large dollar advantage for Southlake households specifically compared to an equivalent income in a state that taxes income progressively.
Southlake's Combined Sales Tax Rate
The combined sales tax rate in Southlake is 8.25% as of 2026, per Avalara rate data reviewed August 2026: the state's 6.25% base rate plus 1.75% city sales tax and 0.25% special-purpose-district tax. This is the statutory ceiling Texas law allows local jurisdictions to reach -- the same maximum already cited for Dallas and Denton in this build, not a Southlake-specific outlier.
Property Taxes: A High Bill in Dollar Terms
The City of Southlake's own adopted (and, per Fort Worth Report coverage from August 2025, trending downward) property tax rate was proposed at $0.295 per $100 of assessed value for fiscal year 2026-27, down from $0.305 the prior year -- continuing a multiyear trend of the city council lowering its own rate. That city-only rate is just one layer of the full bill, which also includes Tarrant County, Carroll ISD, and other overlapping levies. Aggregated property-tax research (Ownwell, reviewed August 2026) cites a median effective combined rate around 1.22% for the 76092 ZIP code, with a median annual property tax bill around $13,633 -- more than five times the $2,400 national median, a direct function of Southlake's high home values rather than an unusually high rate by DFW standards. Confirm your specific parcel's current rate and assessed value against the Tarrant Appraisal District before budgeting precisely.
2026 Homestead Exemption Increase
Texas's general homestead exemption for school-district property taxes rose to $140,000 in 2026 (up from $100,000), a statewide change applying fully in Southlake -- removing that amount from a primary residence's taxable value for Carroll ISD's school-district levy specifically. Seniors (65+) and homeowners with a qualifying disability receive an additional $60,000 school-district exemption ($200,000 combined), plus a school-tax ceiling that freezes that specific levy at qualification-year levels -- see the retiring topic page for how this affects a Southlake retiree's tax picture. Texas also caps annual appraised-value increases on a homesteaded residence at 10% per year statewide, a real protection in a market that has seen sharp valuation swings.
Key takeaways
- No Texas state income tax -- applies statewide, and a particularly large dollar advantage given Southlake's high median household income (~$250,001).
- Southlake's combined sales tax rate is 8.25% (6.25% state + 2% local add-ons) -- the statutory maximum any Texas jurisdiction can reach, matching Dallas and Denton.
- The City of Southlake's own rate was proposed to fall to $0.295/$100 valuation for FY2026-27 (from $0.305), continuing a multiyear downward trend -- but the full combined effective rate (city + county + Carroll ISD + other levies) runs around 1.22% for the 76092 ZIP per one aggregator, producing a median annual bill around $13,633, more than five times the national median.
- Texas's 2026 general homestead exemption ($140,000) and the additional $60,000 senior exemption apply fully in Southlake, alongside a 10%-per-year statewide cap on homestead appraised-value increases.
