How Property Tax Works

Johnson County, Texas operates under the state's property tax system, which serves as the primary funding mechanism for local government services, school districts, emergency services, and infrastructure maintenance. Property taxes in Johnson County fund essential services including public education, law enforcement, fire protection, road maintenance, and county administration. The county follows Texas Property Tax Code guidelines, with property assessments conducted annually by the Johnson County Appraisal District.

The effective property tax rate in Johnson County typically ranges from approximately 2.2% to 2.8% of assessed value, depending on your specific location within the county. This variation occurs because property owners pay taxes to multiple overlapping jurisdictions, including the county, school districts, cities or municipal utility districts, and various special taxing districts such as emergency services districts or water districts. Your exact tax rate depends on which combination of these taxing entities serve your property location. The Johnson County Appraisal District determines property values, while individual taxing entities set their respective tax rates annually.

Supplemental Tax Bills

Supplemental taxes in Johnson County are additional property tax assessments that occur when property ownership changes or when new construction is completed during the tax year. These supplemental bills are issued to account for changes in property value or ownership that occur after the January 1 assessment date but before the current tax year ends.

Supplemental taxes are most commonly triggered by: property sales or transfers, completion of new construction, additions or major improvements to existing structures, or subdivision of land. The supplemental tax is calculated as the difference between the new assessed value and the previous assessed value, multiplied by the applicable tax rate, and prorated for the remaining months in the tax year.

Example: If you purchase a newly constructed home in Johnson County in July with an assessed value of $400,000, and the previous assessed value of the vacant land was $50,000, you would owe supplemental taxes on the $350,000 difference. At a combined tax rate of 2.5%, this would equal $8,750 annually, prorated for 6 months (July-December), resulting in a supplemental tax bill of approximately $4,375 due within 30 days of the bill date.

Escrow & Property Taxes

Most mortgage lenders in Johnson County require property tax escrow accounts for borrowers with less than 20% down payment, though some lenders require escrow regardless of down payment amount. Your lender collects monthly property tax payments as part of your mortgage payment, deposits these funds into an escrow account, and pays your annual property tax bill directly to Johnson County on your behalf.

Lenders typically collect 1/12 of your estimated annual property tax bill each month, plus an additional cushion (usually 2-3 months of payments) to ensure sufficient funds are available when taxes are due. Since Johnson County property taxes are due January 31st annually, your lender will pay the bill in January using funds accumulated throughout the previous year. After paying your taxes, your lender will provide an escrow statement showing the transaction.

You should verify that your lender pays your property taxes on time, as you remain ultimately responsible for the tax obligation even when using escrow. Monitor your annual escrow analysis statement for accuracy, and notify your lender immediately of any changes to your property tax exemptions or assessments. If your property taxes increase significantly due to rising assessments or new special district taxes, your lender may require an immediate escrow shortage payment or increase your monthly escrow collection amount.

Frequently Asked Questions

Q: When are Johnson County property taxes due for FY 2025-2026? A: Property taxes are due January 31, 2025. Payments received after February 1st are considered delinquent and subject to penalties and interest charges that accrue monthly.

Q: What tax exemptions are available and do I need to apply? A: Major exemptions include the $100,000 school district homestead exemption (requires application), county homestead exemption of $5,000 or 5% of value, over-65 exemptions, disability exemptions, and veteran exemptions. ALL exemptions require application with the Johnson County Appraisal District by April 30th annually. Applications are not automatic.

Q: How does the homestead exemption work? A: The homestead exemption provides two benefits: it reduces your taxable assessed value (by $100,000 for school taxes), and it caps your assessment increases at 10% annually. You must file an application with supporting documentation. The 10% cap applies to the total assessed value for tax purposes, not market value.

Q: When does the county assess property values and how can I appeal? A: Property values are assessed as of January 1st each year. Assessment notices are mailed by April. You can protest your assessment with the Johnson County Appraisal Review Board through May 31st (or within 30 days of receiving your notice if later). File protests at johnsoncad.com or call (817) 556-6600.

Q: What are the penalties for late property tax payments? A: Penalties begin at 7% for February, increase to 8% in March, 9% in April, 10% in May, 11% in June, and 12% from July forward. Interest accrues at 1% monthly. Additional attorney fees may apply for severely delinquent accounts.

Q: Can I pay my Johnson County property taxes online? A: Yes, visit the Johnson County Tax Assessor-Collector website or search for "Johnson County Texas tax payments." E-check payments typically have lower fees than credit card payments. You can also pay in person, by mail, or by phone.

Q: Why do properties in the same neighborhood have different tax rates? A: Johnson County contains multiple overlapping taxing entities including different school districts, municipal utility districts, emergency services districts, and other special districts. Your specific combination of taxing entities determines your total rate, which can vary significantly even within the same subdivision.

Q: What triggers a supplemental tax assessment? A: Property sales, new construction completion, major renovations, property splits or combinations, and changes in property use can trigger supplemental assessments. These are prorated for the portion of the tax year remaining after the change occurs.

Q: Are there additional exemptions for seniors or disabled property owners? A: Yes, property owners 65 or older qualify for additional exemptions and a tax ceiling that freezes school district taxes at the level when the exemption begins. Disabled persons may qualify for similar benefits. Both require annual application and documentation with the appraisal district.

Q: How do I verify my property is in the correct taxing districts? A: Check your tax bill or contact the Johnson County Appraisal District at (817) 556-6600. Your property account will list all applicable taxing entities. If you believe there's an error in district assignments, you can protest this with the appraisal review board.
