How the tax estimator works

The tax estimator follows the method on the county’s rate sheet, using that sheet’s figures for the district you choose:

1. Taxable value = appraised value × 35%.
2. Tax at the full rate = taxable value × the district’s total mills ÷ 1,000.
3. Reduction = that tax × the district’s reduction factor (Class I for homes and farms, Class II for commercial property).
4. Credits = the tax after reduction × the non-business credit factor (homes and farms) and × the owner-occupancy factor (owner-occupied homes).
5. Homestead, if chosen, removes the tax on the exempt part of the value, in proportion.
6. The HB 186 credit is shown separately: appraised value ÷ 100,000 × the county’s credit for the school district.

The same method produces the worked examples throughout the site and the “tax per $100,000” column in our tax rates table. An automated check recalculates every example and table row from the county’s data before each update is published.

Other tables and figures we calculate

• Effective rates are the county’s full rates after its reduction factors: full rate × (1 − reduction factor).
• Homestead savings use the exempt amount × 35% × the district’s effective rate, after credits.
• Parcel number formats and counts come from our analysis of the county’s public GIS parcel data. The county doesn’t publish a description of its numbering, and our pages say so.
• CAUV parcel counts come from the same GIS data and are labeled as our count.

Data files

Our tools read two public data files, so anyone can check them: tax-rates.json, with the county’s tax year 2025 figures for every district, and facts.json, with dog license fees and office details. Each file lists its sources and the date it was checked.

Limits of our tools

• Estimates leave out special assessments, unpaid amounts, penalties and the county’s exact rounding.
• Rates change every tax year. Until the county publishes the next rate sheet, our tools use tax year 2025 figures.
• Eligibility checkers give a likely answer, not a decision. Only the Auditor’s office can approve an application.
• Maps and parcel lines are for taxation, not surveys.

Your bill from the Treasurer and decisions from the Auditor’s office are always final. See our disclaimer.
