Harris County’s Property Tax Rate Hike: What It Means for Your Bill, and How to Fight Back
Harris County homeowners are facing one of the steepest property tax increases in the county’s modern history. On September 17, 2026, county commissioners voted 3-1 to adopt a historic combined property tax rate of $0.67 per $100 of taxable value, roughly a 7.6% to 7.9% increase over the previous rate, and the highest the county has seen in nearly two decades. Commissioners also adopted a $3.1 billion county budget in a separate 3-2 vote.
The new rate is tied to the fiscal year beginning October 1, 2026. For the average $400,000 home, it adds an estimated $193 to $198 per year on the county portion of the tax bill alone, and for many homeowners, the real number will be higher.
Here’s what every Harris County property owner needs to understand about how this works, why the impact won’t be the same for everyone, and what you can do to challenge what you owe.
Tax Rate vs. Appraised Value: The Two Numbers That Decide Your Bill
Your property tax bill is the product of two separate things, set by two separate bodies:
1. Appraised (or assessed) value. This is what your property is worth according to the Harris Central Appraisal District (HCAD). HCAD assesses the value of your home every year. Your taxable value is the appraised value minus any exemptions you qualify for (like a homestead exemption).
2. Tax rate. This is the percentage applied to your taxable value, set by the taxing entities: the county, school district, city, and others. The rate is usually expressed as an amount per $100 of taxable value.
The basic formula looks like this:
Taxable Value ÷ 100 × Tax Rate = Tax Owed
So a home with a $300,000 taxable value at the new rate of 67 cents per $100 would owe roughly $2,010 for the county portion.
Why This Increase Won’t Hit Everyone Equally
Here’s the part county headlines often gloss over: the “average” increase figure assumes your appraised value stays flat. It usually doesn’t.
Because your bill depends on both numbers, a rate increase and an appraisal increase can stack on top of each other. If the county raises the rate and HCAD raises your appraised value in the same year, your bill can jump far more than the “$193 to $198” averages suggest. Two homeowners on the same street can see very different increases depending on their appraised values and which exemptions they carry.
This is exactly why the rate hike matters so much, and why it’s worth making sure the other half of the equation, your appraised value, is accurate and fair.
You Can’t Vote on the Rate, But You Can Challenge Your Appraisal
The tax rate has now been set by elected officials, and it’s locked in for the coming fiscal year. The appraised value, though, is something you have a direct legal right to contest.
Every Harris County property owner can protest their appraised value with HCAD each year. A successful protest lowers your taxable value, which lowers your bill at any tax rate, meaning it directly offsets the sting of this rate increase. Grounds for a protest commonly include:
- Your appraised value is higher than the property’s actual market value
- Your property is assessed unequally compared to similar nearby homes
- Errors in HCAD’s records (wrong square footage, condition, lot size, etc.)
- Missing exemptions you’re entitled to, like the homestead or over-65 exemption
With the county rate now at its highest point in nearly 20 years, an inflated appraisal costs you more than it would have before. Getting your value corrected is one of the few levers a homeowner actually controls.
What You Should Do Now
- Check your appraised value on your latest HCAD notice and compare it against recent sales of similar homes nearby.
- Confirm your exemptions are all in place. Many homeowners miss out on hundreds of dollars simply because an exemption wasn’t filed.
- Mark your calendar for the 2027 protest season so you don’t miss the deadline to challenge your appraised value.
- Get a professional review if your appraisal looks high, unequal, or contains errors.

Frequently Asked Questions
How much is the new Harris County property tax rate?
Harris County commissioners adopted a combined property tax rate of $0.67 per $100 of taxable value on September 17, 2026. That’s roughly a 7.6% to 7.9% increase over the previous rate, and the highest rate the county has set in nearly two decades. The new rate takes effect with the fiscal year beginning October 1, 2026.
How much more will I pay because of the increase?
For an average $400,000 home, the county estimates the increase adds about $193 to $198 per year on the county portion of your tax bill. Your actual increase could be higher or lower depending on your home’s appraised value, the exemptions you carry, and whether HCAD raised your appraised value in the same year.
What’s the difference between my tax rate and my appraised value?
Your appraised value is what your home is worth according to the Harris Central Appraisal District (HCAD). Your tax rate is the percentage applied to that value by taxing entities like the county. Your bill is calculated by taking your taxable value (appraised value minus exemptions), dividing by 100, and multiplying by the tax rate. Both numbers affect what you owe, but you can only challenge one of them: your appraised value.
Can I lower my property tax bill after the rate increase?
Yes. While you can’t change the tax rate, you can protest your appraised value with HCAD. A successful protest reduces your taxable value, which lowers your bill at any tax rate. That makes it one of the most effective ways to offset the impact of the rate increase.
When can I protest my Harris County appraisal?
HCAD typically mails appraisal notices in the spring, and the general deadline to file a protest is May 15 (or 30 days after your notice is delivered, whichever is later). Watch for your 2027 notice and file before the deadline to challenge your value for that tax year.
What are common grounds for a property tax protest?
The most common grounds include an appraised value that’s higher than your home’s actual market value, an unequal appraisal compared to similar nearby homes, errors in HCAD’s records (like incorrect square footage or lot size), and missing exemptions you’re entitled to, such as the homestead or over-65 exemption.
Do I need a professional to protest my property taxes?
You can file a protest yourself, but many homeowners choose to work with a property tax professional who knows how to build a strong case, gather comparable sales data, and negotiate with HCAD. At Republic Property Tax, we handle the entire process for Harris County homeowners so you don’t leave money on the table.
