How Property Tax Works

Harris County operates under Texas's property tax system, where local taxing entities including the county, school districts, municipalities, and special districts levy taxes to fund essential public services such as schools, infrastructure, emergency services, and local government operations. The Harris Central Appraisal District (HCAD) serves as the central authority for property assessments, while the Harris County Tax Office handles tax collection and payment processing.

Property owners in Harris County can expect an effective tax rate around 2.4% to 3.2% of their property's assessed value, depending on their specific location and the combination of taxing entities that serve their area. Texas law provides significant protections for homeowners, including a homestead exemption that removes $100,000 of value from school district taxation for primary residences, and a 10% annual cap on assessed value increases for homesteaded properties. The county's tax year runs from January 1 to December 31, with taxes typically due by January 31 of the following year.

Section 4

Supplemental Tax Bills

Supplemental taxes in Harris County are additional property tax assessments that occur when there are changes to a property's ownership, value, or tax status during the tax year. The most common triggers include new construction or improvements completed after the January 1 assessment date, changes in property ownership, removal of exemptions, or corrections to the original assessment. When improvements are made to a property, HCAD will assess the additional value and prorate the taxes for the remaining months of the tax year.

For example, if a homeowner completes a $100,000 home addition in July, HCAD would assess this improvement and calculate supplemental taxes for the remaining six months of the tax year. With a combined tax rate of 2.5%, the annual tax on the improvement would be $2,500, but the supplemental bill would be prorated to $1,250 (6 months ÷ 12 months × $2,500). Business personal property that becomes delinquent may incur additional collection fees of 15-20% after April 1st, while real property delinquent taxes also incur penalties and interest charges.

Escrow & Property Taxes

Most mortgage lenders in Harris County require borrowers to establish an escrow account to ensure property taxes are paid on time. The lender collects monthly escrow payments along with your mortgage payment, typically calculating 1/12 of your annual property tax bill plus a cushion amount. Lenders must provide an annual escrow analysis showing how your payments were applied and any adjustments needed for the coming year. When property taxes increase, your monthly escrow payment will be adjusted accordingly, often resulting in a one-time shortage payment or higher monthly payments.

Property owners should verify their tax information through the Harris County Tax Office website at https://www.hctax.net/ to ensure their escrow company has accurate tax amounts. The tax office provides online access to current and historical tax statements, payment history, and tax rate information. If you pay your own taxes without escrow, remember that Harris County property taxes are due by January 31st each year, with penalties and interest applied to late payments. Online payment options, installment plans, and electronic statement delivery are available through the county's website.
