Understanding Your Tax Burden: Property, Income, and Sales Tax

Understanding your tax burden is critical for Houston homeowners, especially as property taxes continue to rise. The tax burden is the total amount of taxes you pay relative to your income, and it varies depending on the type of tax:

• Property Tax:
  Houston homeowners face some of the highest property tax rates in the nation, averaging 2.23% of a home’s assessed value in 2025. For a $300,000 home, this results in an annual tax bill of $6,690. Property taxes are based on appraised values, which can be protested to lower your bill. Tools like TaxLasso simplify this process, providing professional-level insights in just 5 minutes—saving you hours of DIY research or thousands of dollars compared to hiring a legal firm.

• Income Tax:
  Texas has no state income tax, a significant advantage for Houston residents. However, federal income taxes still apply, and deductions for property taxes are capped at $10,000, impacting high-value homeowners.

• Sales Tax:
  Houston’s combined sales tax rate is 8.25%, one of the highest in Texas. While this doesn’t directly affect homeowners, it contributes to the overall tax burden, especially for those making large purchases.

The Challenge of High Property Taxes in Houston

Property taxes represent the most significant and controllable part of your tax burden. If your home’s appraised value is too high, you’re likely overpaying. Protesting your property tax valuation can save you hundreds or even thousands annually.

• DIY Approach: Time-consuming and complex, often requiring hours of research.
• Legal Firms: Expensive, with fees often exceeding $1,000.
• TaxLasso: The ideal middle ground—affordable, fast (just 5 minutes), and effective, providing you full control without the high cost.

By taking action now, you can reduce your property tax burden and keep more of your hard-earned money.

Why Taxes Are So High: 5 Key Factors

Houston homeowners often wonder why their property taxes are so high. The answer lies in a combination of local policies, rising property values, and funding needs for essential services. Here are the 5 key factors driving high taxes in 2025:

1. Rising Property Valuations
   Houston’s booming real estate market has led to significant increases in home valuations. In 2025, the average home value in Harris County is projected to rise by 8-10%, directly impacting tax bills. Higher valuations mean higher taxes, even if tax rates stay the same.

2. Local Government Spending
   Counties and school districts rely heavily on property taxes to fund services like education, infrastructure, and public safety. In 2025, Houston-area school districts are expected to increase budgets by 5-7%, pushing tax rates higher.

3. Lack of State Income Tax
   Texas has no state income tax, which means property taxes are a primary revenue source. This places a heavier burden on homeowners compared to states with diversified tax systems.

4. Tax Rate Increases
   Local governments may raise tax rates to meet growing demands. For example, Harris County’s 2025 budget includes a proposed 3% tax rate hike to address infrastructure projects.

5. Limited Homestead Exemptions
   While Texas offers homestead exemptions, they often don’t keep pace with rising valuations. In 2025, the exemption cap remains at $40,000, providing minimal relief for homeowners facing double-digit valuation increases.

What Can Houston Homeowners Do?

If you’re facing high taxes due to rising valuations, consider protesting your property tax assessment. Tools like TaxLasso make it easy to file a protest in just 5 minutes, saving you hours of DIY research or thousands of dollars compared to hiring a legal firm. TaxLasso combines affordability, professional insights, and full homeowner control, making it the ideal solution for reducing your tax burden.
