How Property Tax Works

Medina County, Texas operates under the state's property tax system, which serves as the primary funding mechanism for local government services including schools, county operations, municipal services, and special districts. Property taxes in Medina County fund essential services such as public education, law enforcement, fire protection, road maintenance, and emergency services. The county follows Texas Property Tax Code regulations, with tax bills typically reflecting a combined rate from multiple taxing entities.

Effective property tax rates in Medina County vary significantly by location within the county due to the presence of different municipal boundaries and special taxing districts. While the base county-wide components remain consistent, residents may pay additional taxes to cities like Castroville, school districts, municipal utility districts, or other special purpose districts depending on their property's location. For the 2025 tax year, Medina County implemented a 9.84% increase in its tax rate, adding approximately $5.20 annually for maintenance and operations on a $100,000 assessed home value.

Supplemental Tax Bills

Supplemental taxes in Texas are generally limited, as the state follows an annual assessment and billing cycle rather than California-style supplemental assessments. However, property tax adjustments can occur when new construction is completed after the January 1 assessment date, or when property ownership changes trigger a reassessment that removes previous exemptions. Under Texas law, new improvements to property may be assessed pro-rata for the remaining tax year once construction reaches a taxable stage.

For example, if a homeowner completes a $100,000 addition to their home in June (after the January 1 assessment date), the addition may be subject to pro-rated taxation for the remaining seven months of that tax year. The calculation would take the improvement value ($100,000), apply the local tax rate (approximately $2.00 per $100), resulting in about $2,000 annual tax, prorated to roughly $1,167 for the seven remaining months.

Escrow & Property Taxes

Most mortgage lenders in Medina County require property tax escrow accounts for borrowers with less than 20% equity. Lenders collect monthly payments equal to 1/12th of the annual tax bill plus a cushion (typically 2-3 months). Texas property taxes become due October 1st and are payable without penalty until January 31st of the following year. Most lenders pay taxes in December or January to take advantage of this extended payment period while ensuring timely payment.

Homeowners should verify their escrow analysis annually when receiving statements from their lender. The escrow analysis will show the previous year's actual tax payments and project the coming year's payments based on current assessed values. Property owners can access their current tax information through the Medina County Appraisal District website to verify accuracy. If taxes increase significantly due to rising property values or rate increases, monthly escrow payments will adjust accordingly, sometimes requiring a one-time catch-up payment.

Frequently Asked Questions

Q: When are property taxes due in Medina County for the current fiscal year? A: Property taxes become due October 1, 2024, for the 2024 tax year and can be paid without penalty through January 31, 2025. After January 31st, interest and penalty charges apply.

Q: What homestead exemptions are available and do they apply automatically? A: The primary homestead exemption is $100,000 off assessed value for school district taxes on your primary residence. Additional exemptions up to 20% of value (minimum $5,000) may be offered by cities, counties, or special districts. All exemptions require application - none are automatic.

Q: When must I apply for homestead exemptions? A: Homestead exemption applications are generally due by April 30th of the tax year, though late applications may be accepted in some circumstances. Apply with the Medina County Appraisal District after purchasing a home or establishing residency.

Q: How does the 10% homestead assessment cap work? A: For properties with approved homestead exemptions, the taxable value cannot increase more than 10% annually, regardless of market value increases. This caps assessment growth but does not reduce the actual market value for other purposes.

Q: When can I appeal my property assessment? A: Informal appeals can be filed with the Medina County Appraisal District typically between January and May. Formal appeals to the Appraisal Review Board must generally be filed by May 31st or within 30 days of receiving your tax notice.

Q: What are the penalties for late tax payments? A: Interest accrues at approximately 1% per month on unpaid taxes after January 31st. Additional penalties may apply, and delinquent taxes can result in tax liens and eventual foreclosure proceedings.

Q: Can I pay property taxes online? A: Yes, Medina County offers online payment options through the county tax assessor-collector's website. Payment methods typically include electronic check, credit card, or debit card, though convenience fees may apply for card payments.

Q: How do special district taxes affect my bill? A: Depending on your property location, you may pay additional taxes to Municipal Utility Districts (MUDs), Emergency Services Districts (ESDs), or other special purpose districts. These rates vary significantly by location and are added to your base county and school taxes.

Q: Are there additional exemptions for seniors or veterans? A: Yes, homeowners age 65 and older may qualify for additional exemptions and tax freezes. Disabled veterans and their surviving spouses may also qualify for significant exemptions based on disability rating. These require separate applications with documentation.

Q: What triggers a property reassessment? A: Properties are reassessed annually as of January 1st. However, new construction, major improvements, or changes in property use can trigger interim assessments. Change of ownership alone does not trigger reassessment but may affect eligibility for existing exemptions.
