Market Value vs Assessed Value in Texas: Key Differences Explained

Quick Answer: Market Value vs Assessed Value in Texas

Market value is what your home would sell for in today's market, while assessed value is what your county appraisal district says your property is worth for tax purposes. In Texas, your assessed value directly determines your property tax bill, but it may be capped below market value thanks to the homestead exemption's 10% annual increase limit.

Understanding the Three Key Property Values

Texas homeowners encounter three different property values each year. Here's what each one means:

Market Value (What Your Home Could Sell For)

Market value represents the price your home would likely sell for in the current real estate market. This figure changes based on:

• Recent comparable sales in your neighborhood
• Current buyer demand
• Interest rates and financing availability
• Local economic conditions
• Seasonal market fluctuations

Real estate agents typically determine market value through a Comparative Market Analysis (CMA) using recent sales of similar homes.

Appraised Value (County's Market Value Estimate)

Your county appraisal district estimates your property's market value as of January 1st each year. This becomes your "appraised value" on your property tax notice. Texas law requires this appraised value to represent market value.

Counties use mass appraisal techniques, analyzing:

• Property characteristics (size, age, condition)
• Recent sales data
• Construction costs
• Income potential for commercial properties

Assessed Value (What You're Taxed On)

Assessed value is your taxable value after exemptions and caps are applied. This number determines your actual property tax bill.

Key Point: In many Texas counties, assessed value stays below appraised value due to the homestead cap, even when home values rise rapidly.

How the Texas Homestead Cap Works

The homestead exemption includes a 10% annual increase cap on assessed value for your primary residence. Here's how it protects homeowners:

Example: Homestead Cap in Action

Let's say you bought a home in Austin in 2023:

• 2023: Appraised value $400,000 = Assessed value $400,000
• 2024: Appraised value $480,000, but assessed value capped at $440,000 (10% increase)
• 2025: Appraised value $520,000, but assessed value capped at $484,000 (10% increase)
• 2026: Appraised value $550,000, but assessed value capped at $532,400 (10% increase)

Without the cap, this homeowner would pay taxes on an additional $17,600 in value for 2026 alone.

When the Cap Doesn't Apply

The 10% cap has important limitations:

• Only applies to homestead properties (your primary residence)
• Doesn't apply to new improvements you add
• Resets when you sell the home
• Doesn't apply to other exemptions like over-65 or disability

Real-World Examples from Major Texas Counties

Harris County Example (Houston Area)

According to Harris County Appraisal District data, the median home value increased 23% between 2023 and 2024. However, homestead properties saw assessed values increase by only 10% due to the cap.

A typical scenario:

• Market value (per recent sales): $385,000
• County appraised value: $380,000
• Assessed value (with homestead cap): $345,000
• Property tax calculation based on: $345,000

Travis County Example (Austin Area)

In rapidly appreciating areas like Austin, the gap between market and assessed value can be substantial. A home that sold for $650,000 in 2024 might have an assessed value of only $520,000 due to the homestead cap.

Why These Differences Matter for Property Tax Protests

Understanding these values helps homeowners evaluate whether to file a property tax protest:

When Market Value Evidence Helps

If recent comparable sales show your home's market value is lower than the county's appraised value, you may have grounds for a protest. Homeowners often use:

• Recent sales of similar homes
• Professional appraisals
• Market condition reports
• Property condition issues

When the Homestead Cap Provides Sufficient Protection

If your assessed value is already capped significantly below both market value and appraised value, protesting may not provide additional tax savings.

Consider This: Even if you successfully reduce appraised value, your assessed value might not change due to the homestead cap.

How to Find Your Property Values

Texas counties provide this information on your annual property tax notice and online:

What to Look For

• "Market Value" or "Appraised Value": The county's estimate
• "Assessed Value" or "Taxable Value": What you're actually taxed on
• "Homestead Cap Savings": Dollar amount the cap saved you

• Travis County: traviscad.org

Impact on Your Property Tax Bill

Your property tax calculation works like this:

1. Start with assessed value (after exemptions and caps)
2. Multiply by total tax rate (city + county + school + other)
3. Result = your annual property tax bill

Example Calculation

For a home in Plano (Collin County):

• Assessed value: $450,000
• Total tax rate: 2.1% (combined rate for area)
• Annual property tax: $9,450

If the assessed value were $50,000 lower due to a successful protest, the tax savings would be approximately $1,050 annually.

Bottom Line: What This Means for Texas Homeowners

The difference between market value and assessed value can significantly impact your property tax bill. The homestead cap provides valuable protection in rising markets, but it's important to understand when protesting might still provide additional savings.

Homeowners have several options for addressing property tax concerns: filing their own protest using county websites, working with tax consultants, or using document preparation services like FairPath ($249 flat fee) to prepare professional evidence packets.

The key is understanding which value matters most for your situation and whether the gap between appraised value and market evidence justifies taking action.
