How Property Tax Works

Fannin County, Texas operates on a property tax system that serves as the primary funding source for essential local services including public education, county operations, emergency services, and infrastructure maintenance. Property owners pay taxes based on the assessed value of their property multiplied by the applicable tax rate, which varies by location within the county due to different combinations of taxing entities such as school districts, cities, and special districts.

The effective property tax rate in Fannin County for 2025 is approximately $2.35816 per $100 of assessed valuation for the county portion, though total rates typically range from $2.50 to $3.50 per $100 when including all applicable taxing entities. Property assessments in Texas are capped at 10% annual increases for homestead properties, and the state provides a $100,000 homestead exemption for school district taxes. Most exemptions and credits require formal application and are not automatically applied to your property tax bill.

Section 4

Supplemental Tax Bills

Supplemental taxes in Fannin County are triggered when there are changes to property ownership or improvements that occur after the January 1st assessment date. Common triggers include new construction completion, property sales that prompt reassessment, or the addition of structures like pools, garages, or home additions. The supplemental tax is calculated as the difference between the new assessed value and the previous assessed value, multiplied by the applicable tax rate, prorated for the remaining months in the tax year.

For example, if you complete a $50,000 home addition in July and your total tax rate is $3.00 per $100, you would owe a supplemental tax of approximately $750 ($50,000 ÷ 100 × $3.00) prorated for 6 months, resulting in a supplemental bill of about $375. Supplemental taxes are billed separately and have their own due dates, typically 30 days from the bill date.

Escrow & Property Taxes

Most mortgage lenders in Fannin County require property tax escrow accounts, where you pay 1/12th of your estimated annual property taxes with each monthly mortgage payment. Lenders typically collect an initial escrow deposit at closing equal to 2-3 months of taxes, then analyze the account annually to ensure adequate funds. Property tax bills are sent directly to your mortgage servicer, who pays the taxes on your behalf when due.

Texas property taxes are due by January 31st of the following year, though some entities may offer split payment options. If your escrow account has a shortage due to assessment increases or rate changes, your lender will either increase your monthly payment or request a lump sum to cover the deficit. You can request an escrow analysis statement from your lender at any time to verify the calculations and projected payments for the upcoming year.

Frequently Asked Questions

Q: When are property taxes due in Fannin County for the 2025 tax year? A: Property taxes for 2025 are due by January 31, 2026. Some taxing entities may offer split payment options with installments due by different dates.

Q: What homestead exemptions are available and how do I apply? A: The primary homestead exemption is $100,000 off assessed value for school district taxes. You must apply with the Fannin County Appraisal District by April 30th following the year you establish homestead. This is not automatic and requires filing Form 50-114.

Q: How does the homestead 10% assessment cap work? A: For homestead properties, the assessed value cannot increase more than 10% annually, regardless of market value increases. This cap limits assessment growth but doesn't reduce current market value. You must have a homestead exemption on file to qualify.

Q: Are there additional exemptions for seniors or veterans? A: Yes, residents 65 and older can receive additional exemptions and a tax ceiling that freezes school taxes. Disabled veterans may qualify for various exemptions based on disability rating. All require separate applications with supporting documentation.

Q: How do I appeal my property assessment? A: You can protest your assessment with the Fannin County Appraisal Review Board. Informal protests can be filed starting in April, with formal hearings typically held May through July. The deadline is usually May 31st or 30 days after your notice of value.

Q: What are the penalties for late payment? A: Texas law allows penalties of 6% in February, 7% in March, 8% in April, 9% in May, 10% in June, and 12% in July and thereafter, plus 1% interest per month.

Q: Can I pay my property taxes online? A: Yes, most Fannin County taxing entities offer online payment options through their websites or third-party services. Check with your specific tax collector for available payment methods and any associated convenience fees.

Q: Why did my taxes increase when rates went down? A: Even when tax rates decrease, your total tax bill can increase due to rising property assessments. The 10% homestead cap helps limit assessment increases, but new construction and improvements in your area can still affect overall tax calculations.
