Houston’s Property Tax Changes Explained: What Owners & Buyers Should Prepare For
Houston’s property tax landscape is shifting in 2025, with new updates making waves for current homeowners, new buyers, and real estate investors. Here’s what you need to know to stay ahead of the curve, protect your wallet, and confidently make real estate decisions in the Bayou City.
How Houston’s Property Taxes Work
Property taxes in Houston are made up of several components:
- City of Houston tax
- Harris County tax
- Houston ISD (Independent School District) tax
- Special taxes (like MUDs—Municipal Utility Districts) depending on where you live
For 2025, the key tax rates are:
- City of Houston: $0.51919 per $100 of assessed value
- Harris County: $0.38529 per $100
- Houston ISD: $0.86830 per $100
On top of those, MUD or special district taxes can add a few hundred to several thousand dollars annually, depending on your property’s location.
Each year, the Harris Central Appraisal District (HCAD) assesses the market value of your property as of January 1. These values—combined with the tax rates—determine what you’ll owe in the coming year.
What’s New: 2025 Assessment Changes
This year, the biggest news is rising property values, not increases in the tax rate itself. Based on recent HCAD numbers:
- Harris County property tax bills are set to rise by a whopping $1.05 billion in 2025.
- Homeowners are picking up around 51% of that increase.
- 56% of single-family homes had values go up since last year.
- If your home is valued at $750,000 or more, there’s an 84% chance you saw your home’s assessed value increase.
- Luxury homes and new apartments are facing the largest jumps in taxes.
These changes are mainly due to Houston’s hot housing market throughout 2024—demand drove prices up, and now those higher values are reflected on appraisal notices.
Important Deadlines: What, When & How to Pay
Understanding when and how to pay property taxes can keep you in the clear from late fees and penalties. Here’s the rundown for Houston:
- First Installment Due: October 1
(Becomes delinquent after November 30) - Second Installment Due: February 1
(Becomes delinquent after January 31)
Even though bills are annual, many mortgage lenders collect estimated taxes each month in escrow—so your payment schedule might feel more spread out.
If you just bought your home, double-check with your lender to be sure your taxes are included in your mortgage payment.
Appeals: Fighting a High Assessed Value
Think the county valued your house too high? You’re not alone—about 3 in 10 Houston homeowners appealed their assessments in 2024. And here’s the good news: a strong case can get you real savings.
- Appeal Deadline: May 15 OR 30 days after your notice
- Who Should Appeal: Anyone whose notice shows a dramatic increase or feels out of step with similar homes nearby
- What You Need: Comparable recent sales, photos, repair estimates, and any other evidence your home’s value is overstated
Don’t wait—successful appeals can save you hundreds, even thousands. For best results, consult a qualified tax protest firm or real estate expert familiar with Houston’s market.
Special Tips for Buyers (Especially First-Timers)
Buying in Houston for the first time? Here’s what you should know about property taxes:
- On closing, you become responsible for any unpaid taxes. Do your due diligence!
- First-year taxes are usually included in your monthly mortgage payments via escrow.
- New construction: Your initial appraisal might be based on the sale price or a “cost approach.” Watch for a jump in your second-year bill.
- Exemptions from the previous owner (homestead, senior, veteran) don’t automatically transfer—file any that apply to you as soon as possible.
If you’re concerned about a high first-year bill, ask your agent or lender for a property tax estimate before closing.
Exemptions—Are You Taking Advantage?
Property tax exemptions can make a serious dent in your bill, so make sure you’re getting every break you qualify for:
- Homestead exemption: Most common; available to primary residence owners
- Senior or disabled exemption: For homeowners age 65+ or with disabilities
- Veteran exemption: For qualifying veterans
For a full list and how to apply, check with HCAD or visit the City of Houston’s property tax resources. Always update your exemptions ASAP after a move.
How Market Trends Impact Your Tax Bill
Here’s the catch—the rates only tell half the story. Houston’s tax rates have stayed steady (or even dropped a bit), but your home’s value is likely climbing because:
- The supply of homes has been tight, especially in popular neighborhoods.
- Houston is seeing plenty of luxury and new construction projects.
- Texas’ strong job market keeps the pressure on prices.
Your bill will reflect market value jumps—even without a rate hike. Stay alert to neighborhood trends and review your annual assessment for accuracy.
Quick Action Plan: How To Stay Ahead
- Open your assessment notice as soon as it arrives
- Compare values with similar properties in your area—check HAR and recent sales
- Mark your calendar for appeal dates and paperwork deadlines
- Ask your lender or title agent about your property tax escrow
- Double-check your exemptions each year
