How Property Tax Works

Marion County, Texas operates under the state's property tax system to fund essential local services including schools, county operations, emergency services, and infrastructure maintenance. Property taxes are levied annually based on the assessed value of real estate and personal property, with the tax year running from January 1 to December 31. The county's adopted tax rate for 2025 is $0.5358775 per $100 of assessed valuation, which represents an increase from the previous year's no-new-revenue rate of $0.5180983 per $100.

Property owners should note that actual tax rates vary significantly by location within Marion County due to overlapping special taxing districts, including school districts, municipal utility districts, and other local entities. The total effective tax rate typically ranges from approximately 2.0% to 2.8% of assessed value when combining county, school district, and local municipal taxes. Texas law caps annual assessment increases at 10% for homestead properties, and the state provides a substantial $100,000 homestead exemption for school district taxes on primary residences.

Supplemental Tax Bills

Supplemental taxes in Marion County are additional property tax assessments that occur when there are changes to property ownership, improvements, or new construction after the annual assessment date of January 1. These supplemental bills are calculated based on the difference between the old and new assessed values, prorated for the remaining months in the tax year. Common triggers include home sales, major renovations, new construction completion, or additions that increase property value.

For example, if you purchase a home in Marion County in July and the new assessed value is $50,000 higher than the previous assessment, you would receive a supplemental tax bill for the increased value covering July through December (6 months). The calculation would be: ($50,000 ÷ $100) × applicable tax rate × (6 months ÷ 12 months). With a combined tax rate of 2.5%, this would result in a supplemental tax of approximately $625. Supplemental taxes are due within 30 days of the bill date and become delinquent if not paid, subject to penalties and interest.

Escrow & Property Taxes

Most mortgage lenders in Marion County require property tax escrow accounts to ensure timely payment of property taxes. Your lender collects a portion of your estimated annual property tax bill with each monthly mortgage payment, typically one-twelfth of the annual amount. The lender deposits these funds into an escrow account and pays your property taxes directly to Marion County when bills are due. Texas law requires property tax payments by January 31st annually, though Marion County offers a split payment option with installments due October 15th and December 1st.

Your lender will provide an annual escrow analysis statement showing the previous year's tax payments and adjusting your monthly escrow amount based on current tax assessments. If your property taxes increase due to rising property values or rate changes, your monthly mortgage payment may increase to cover the higher escrow requirement. Conversely, if you successfully appeal your assessment or qualify for new exemptions, your escrow amount may decrease. Property owners should review their annual tax statements and notify their lender of any discrepancies to ensure accurate escrow calculations.

Frequently Asked Questions

Q: When are Marion County property taxes due for the current fiscal year? A: Property taxes are due by January 31st annually. However, Marion County offers split payment options with first installment due October 15th and second installment due December 1st. Taxes become delinquent February 1st and incur penalties and interest.

Q: What homestead exemptions are available and how do I apply? A: The primary homestead exemption provides $100,000 off assessed value for school district taxes only. You must apply with the Marion County Appraisal District by April 30th of the tax year. The exemption also caps annual assessment increases at 10%. Additional exemptions are available for seniors (65+), disabled veterans, and disabled persons - all require separate applications.

Q: How does the 10% homestead cap work? A: For properties with approved homestead exemptions, the assessed value for tax purposes cannot increase more than 10% annually, regardless of market value increases. This caps assessment growth, not the actual market value. If market value increases 20%, your taxable assessment can only increase 10% that year.

Q: When can I appeal my property assessment? A: Property owners may file appeals with the Marion County Appraisal Review Board typically between May 1st and July 25th annually. You'll receive a notice of appraised value in April with specific appeal deadlines and procedures. Appeals must be filed within 30 days of receiving your notice.

Q: What are the penalties for late property tax payments? A: Taxes become delinquent February 1st and incur immediate penalties of 6% in February, 7% in March, and 8% from April forward. Interest accrues at 1% per month. Attorney fees may be added for collection actions, and properties can eventually be subject to tax foreclosure.

Q: Can I pay my property taxes online? A: Yes, Marion County typically offers online payment options through the county tax office website. Payment methods usually include electronic check, credit card, and debit card, though convenience fees may apply for card payments.

Q: Why do tax rates vary within Marion County? A: Property tax bills combine multiple taxing entities - county, school districts, cities, and special districts (MUDs, utility districts, etc.). Each sets its own rate, so your total rate depends on which combination of districts serves your specific property location.

Q: Are there property tax exemptions for veterans? A: Yes, disabled veterans may qualify for exemptions based on their disability rating. Veterans with 10% or higher service-connected disabilities can receive partial exemptions, while 100% disabled veterans may qualify for total exemptions. Surviving spouses may also qualify. Applications must be filed with the Marion County Appraisal District with required VA documentation.
