Property Taxes on 10 Acres in Texas: How the Bill Is Calculated, How to Estimate It Before You Buy, and How to Lower It (2026)

Texas has no state property tax. Your bill on rural land comes from a county appraisal district's value and the rates of each local taxing unit. Here is the math, the calendar, the homestead exemption and the protest process, with official sources.

TL;DR

Texas has no state property tax. Local taxing units (the county, the school district and, depending on the tract, special districts such as a junior college or hospital district) set rates and collect the tax.
The county appraisal district (CAD) sets the value of your land as of January 1 each year, based on market value unless the land qualifies for a special valuation such as agricultural use.
The formula: taxable value ÷ 100 × each unit's rate (rates are expressed in dollars per $100 of taxable value), added up across every unit that taxes the tract.
You can estimate the bill before you buy using the CAD's public records, the county's "Truth in Taxation" rate table and the appraisal district's property tax database.
Once you live there, a residence homestead exemption (including $140,000 off school district value) and a 10% annual cap on homestead value increases can change the bill a lot. If a value looks wrong, the usual protest deadline is May 15 or 30 days after your notice, whichever is later.

I'm Rodrigo Blanco, Founder & CEO of TerraFunded. Property taxes are the one cost of owning rural land that never goes away. Here is how the bill is built, how to estimate it for a specific 10-acre tract, and how to keep it fair, based on the Texas Comptroller's 2026 Texas Property Tax Basics and the Tax Code.

Who sets the value and who sets the rate

The appraisal district values the property. Each county has an appraisal district that appraises taxable property at market value as of January 1, and it must reappraise all property at least once every three years. Market value is what the property would sell for in the open market, with a reasonable time to find a buyer and both sides knowing its uses and restrictions.

Taxing units set the rates. The Comptroller explains that counties and school districts tax all nonexempt property in their territory, while cities and special purpose districts, such as hospital, junior college or water districts, may also tax. Rural land outside city limits usually pays no city tax, but it can sit inside one or more special districts. Each unit adopts its own rate between late July and the end of September.

Who	What they do	When
Appraisal district (CAD)	Appraises value as of Jan. 1, processes exemptions, sends notices	Jan. 1 to April 30; notices by May 1 for most non-homestead property
Appraisal review board (ARB)	Hears protests	Generally after May 15, most hearings done by July 20
Taxing units (county, school district, special districts)	Adopt tax rates and calculate levies	July 25 to Sept. 30
Tax assessor-collector	Sends bills and collects	Bills begin around Oct. 1; due by Jan. 31

How a CAD values 10 acres of rural land

For vacant rural land, the appraisal district relies mostly on the sales comparison approach: it compares your tract to similar properties that sold recently and adjusts for differences. Under the Tax Code, a sale generally counts as comparable only if it happened within 24 months of the appraisal date (unless there are too few sales), and comparables must be adjusted for things like location, lot size, access and amenities. Easements, deed restrictions and other legal burdens that affect the property's ability to sell must also be considered.

Three things change the value of a 10-acre tract more than anything else:

Improvements. A house, a mobile home you own, a barn or a slab are appraised along with the land. New improvements show up in the next appraisal.
Special valuation. Land that qualifies for agricultural (1-d-1 open-space) appraisal is valued on its capacity to produce agricultural products instead of market value, which usually lowers the taxable value a lot. It is not automatic; the owner must apply. Our Texas ag exemption guide covers qualification, the five-of-seven-year history requirement and rollback.
Splits. If the tract was recently divided from a larger property, the record you find online may still describe the parent property. Ask the CAD how and when the new tract will be appraised on its own.

What does not count: an RV or other personal property you own and do not use to produce income is generally exempt under Tax Code Section 11.14 (manufactured homes are the exception and are taxed).

The formula, with a real-rate example

Texas tax rates are written in dollars per $100 of taxable value. The Tax Code uses that unit for the no-new-revenue and voter-approval rates that every unit calculates. For each taxing unit:

tax = taxable value ÷ 100 × that unit's rate

Then you add the results for every unit that covers the tract. Taxable value is the appraised value minus any exemptions that unit grants, so the taxable value can differ from one unit to the next.

Here is the math with real 2025 rates from the Comptroller's rates and levies files and a hypothetical appraised value of $100,000, chosen only to make the arithmetic easy (it is not a TerraFunded price):

Taxing unit (2025)	Rate per $100	Tax on a $100,000 value
Lamar County	$0.3063	$306.30
North Lamar ISD	$0.8169	$816.90
Total for a tract taxed only by these two units	$1.1232	$1,123.20

The Comptroller's special district file also lists the Paris Junior College District in Lamar County at $0.066324 per $100, marked as a community college district that may collect a tax in some school districts. If a tract falls inside its taxing area, that line is added too. That is the practical lesson: the combined rate depends on exactly which units cover the tract, and two tracts in the same county can have different totals because they sit in different school districts.

How to estimate the bill before you buy

You can do this in about half an hour with public records.

Find the property on the CAD's website. Search by owner, address or property ID. Note the market value, the appraised value and any special valuation or exemptions on the account.
Write down the taxing units. The account lists every unit that taxes the property, and the annual notice of appraised value is required to list them as well.
Get each unit's rate. Tax Code Section 26.16 requires each county's website to post a "Truth in Taxation Summary" table with the adopted rate for each taxing unit in the county for the most recent five years. Section 26.17 requires each appraisal district to maintain a property tax database, searchable by address and owner, that shows a property's market value, taxable value, each taxing unit and its rates, and the taxes that would result.
Do the math for each unit and add the results.
Adjust for what will change. If the current value reflects an agricultural valuation and you will not continue a qualifying use, expect the value to move toward market value and check rollback exposure. If you plan to build, add the improvement. If you will live there, apply the homestead exemption (below).
Check for unpaid taxes. The Comptroller recommends getting a tax certificate from all units that tax a property before buying; it shows whether the prior owner owes delinquent taxes. In a title company closing, Schedule C of the title commitment requires satisfactory evidence that taxes and assessments have been paid.

For some TerraFunded listings, our public property feed includes an estimated annual property tax figure. Treat it as an estimate and confirm it with the CAD.

When you move in: the homestead exemption

What qualifies. A residence homestead is a structure, including a manufactured home you own, that you own and occupy as your principal residence, together with the land used in the residential occupancy of the structure, up to 20 acres. You may receive a residence homestead exemption on only one property in a year. Bare land with no home does not qualify. If the CAD grants the exemption on only part of your acreage, the Comptroller advises showing how much land you actually use as a residence.

What it is worth.

Exemption	Amount	Who must offer it
General residence homestead	$140,000 of appraised value	School districts (required)
Age 65 or older, or disabled	Additional $60,000	School districts (required)
Optional percentage exemption	Up to 20% of appraised value, at least $5,000	Any taxing unit, by local choice
Farm-to-market or flood control	$3,000	Counties that collect those taxes

How to apply. File Form 50-114 with the appraisal district. The general deadline is before May 1, but a homestead application can be filed late, up to two years after the date the taxes become delinquent. If you acquire the home after January 1, you can receive the exemption for the part of the year you own it, as long as the previous owner did not have a homestead exemption on it that year. Once granted, you do not reapply each year unless the chief appraiser asks or your situation changes.

The 10% cap. Starting January 1 of the year after you qualify, the appraised value of your homestead cannot rise more than 10% a year, plus the value of new improvements.

Non-homestead land. Through December 31, 2026, Texas also has a temporary "circuit breaker" that limits yearly increases in appraised value to 20% for qualifying non-homestead real property valued at or below a threshold ($5 million for 2024, adjusted for inflation). It takes effect the year after you first own the property on January 1, and land under special appraisal such as agricultural use is not eligible.

How to protest a value

If the appraised value looks too high, you have the right to protest to the appraisal review board.

Deadline: before May 15 or within 30 days after the notice of appraised value was delivered, whichever is later. If the deadline falls on a weekend or holiday, it moves to the next business day.
Form: the protest must be in writing. You can use Comptroller Form 50-132, or 50-132-A in counties under 120,000 people, but any written notice that identifies you, the property and what you disagree with works.
Informal conference: the appraisal district must offer to meet with you to try to resolve it before the hearing.
Evidence: for a market value protest, sales of comparable properties and facts about the property's condition. For an unequal appraisal protest, a reasonable number of comparable properties, properly adjusted.
After the ARB: the Comptroller describes further appeals to district court, regular binding arbitration or the State Office of Administrative Hearings, each with its own requirements. To appeal, you generally must pay the undisputed amount on time.

For rural land, physical facts often matter most: limited access, a large easement or no utilities nearby are differences the CAD must weigh against comparable tracts.

Paying the bill, and what late costs

Bills start going out around October 1 and are generally due by January 31. On February 1, penalty and interest begin. The Comptroller explains that the penalty can reach 12% depending on how long the taxes stay unpaid, interest accrues at 1% per month with no maximum, and private attorneys hired to collect delinquent accounts can add another 20%. Some tax offices offer local options such as split payments, so ask yours.

Who owes the tax. You owe taxes on property you own on January 1 of the tax year. A tax lien attaches to the property on January 1 to secure that year's taxes (Tax Code Section 32.01) and takes priority over other liens, including a seller's lien (Section 32.05). Read the tax provisions of your Deed of Trust.

How it works at TerraFunded

When you buy from TerraFunded, you receive a Warranty Deed recorded in your name at closing, and the land is legally yours from closing day, not when you finish paying. As the owner of record, the property tax account and the homestead and agricultural applications are yours to manage with the county appraisal district. The closing statement shows how the taxes for the year of the sale are handled. Our listings note that agricultural valuation is not automatic: you apply through the county CAD. Financing is fixed 10% APR for 10 or 15 years with approval without a bank. See current tracts on the marketplace and the steps on how it works.

Frequently asked questions

How much are property taxes on 10 acres in Texas?

There is no single statewide number: it depends on the tract's appraised value and the combined rate of the units that tax it. Divide the taxable value by 100, multiply by each unit's rate and add them up. For scale, a tract taxed only by Lamar County and North Lamar ISD at 2025 rates pays $1.1232 per $100 of taxable value.

How do I find the property tax rate for rural land?

Look up the property on the appraisal district's website to see which taxing units cover it, then check the county's "Truth in Taxation Summary" table (Tax Code Section 26.16) or the appraisal district's property tax database (Section 26.17). The Comptroller also publishes rates and levies for every county, city, school district and special district.

Do I pay city taxes on land outside city limits?

Generally no. Cities tax property inside their limits. Land outside city limits is still taxed by the county and the school district, and it may be inside special districts such as a junior college, hospital or water district.

Can I get a homestead exemption on 10 acres?

Yes, if you own and occupy a home on it as your principal residence. The homestead can include up to 20 acres of land used in the residential occupancy of the home. Vacant land without a residence does not qualify.

When is the deadline to protest my appraisal?

Before May 15 or within 30 days after your notice of appraised value was delivered, whichever is later. File in writing with the appraisal review board; the Comptroller's Form 50-132 or 50-132-A is available but not required.

What happens if I pay my property taxes late?

Penalty and interest start on February 1. The penalty can reach 12%, interest runs at 1% per month with no cap, collection attorneys can add up to 20%, and the tax lien takes priority over other liens on the land.

Does the ag exemption transfer when I buy land?

The agricultural valuation is not automatic for a new owner; you apply with the county appraisal district (Form 50-129) and must keep a qualifying use. See our ag exemption guide for the details and rollback rules.
