How Texas Property Tax Calculations Work

1

Enter Your Property Value

Start with your home's current market value. In Texas, assessed value is typically set at market value each year, but you should check your most recent appraisal notice to be sure.

Texas Tip: Texas assesses properties at full market value every January 1st. Protest your value if it's too high!
2

Select Your Texas County

Each county in Texas has different tax rates. We use the official rates published by each county's appraisal district.

3

Apply Texas Exemptions

Select any exemptions you qualify for, such as homestead, over-65, or veteran exemptions. These reduce your taxable value.

4

Get Your Estimate

We calculate your annual and monthly property tax based on current rates and show you exactly how much you could save with exemptions.

Understanding the Calculation

Your property tax is calculated using this formula:

Property Tax = (Property Value - Exemptions) × Tax Rate

The tax rate includes several components: county general fund, school district, city (if applicable), and special districts like hospitals or community colleges.
