Formula & Theory - Texas Tax Calculator
The Texas Tax Calculator uses these formulas:
State Income Tax = 0
Combined Sales Rate = (6.25% state) + min(Local Rate, 2%)
Sales Tax = Annual Taxable Purchases × Combined Sales Rate
Property Tax = Property Assessed Value × Effective Property Tax Rate
Total Tax = Sales Tax + Property Tax
Effective Rate vs. Income = Total Tax ÷ Annual Income × 100%| Symbol | Meaning |
|---|---|
| Combined Sales Rate | State 6.25% + local rate (capped at 2%) |
| Property Rate | Local effective rate (varies by county/ISD) |
| Effective Rate | Total Texas tax as % of gross income |
Assumptions and Limits
The Texas Tax Calculator ignores sales tax exemptions (groceries, prescriptions, etc.) and property tax exemptions (homestead, senior, disabled). Both can substantially lower real tax. Always check local rules.
