Appraisal District (CAD)
The County Appraisal District or Central Appraisal District (CAD) is the local government entity responsible for discovering, appraising, and valuing all taxable property within a county for property tax purposes. Texas has 254 county appraisal districts, each governed by a board of directors. The CAD determines property values, grants exemptions, maintains property records, and conducts appraisal review board hearings. Understanding how the local appraisal district operates can help property owners review notices, records, evidence, and protest procedures more effectively.

Appraisal Notice (Notice of Appraised Value)
Property owners should review this notice carefully because it may include the protest deadline and information needed to evaluate whether the noticed value or property records should be reviewed.

Appraisal Review Board (ARB)
An independent panel of local citizens appointed by the appraisal district board of directors to hear property tax protests and resolve disputes between property owners and the appraisal district. The ARB conducts informal hearings where property owners present evidence supporting lower valuations and the district defends its appraisal. ARB decisions are binding unless appealed through arbitration or judicial proceedings. Most Texas counties conduct thousands of ARB hearings annually between May and September.

Assessed Value
Assessed value is a value used in the property tax system after applicable exemptions, caps, or special valuations are considered. In some cases, a change in appraised or assessed value may affect taxable value or the tax bill, depending on the property, exemptions, tax rates, and applicable rules.

Business Personal Property (BPP)
Any tangible property owned as of January 1st that is not permanently attached to land, is used for business purposes, and produces income. BPP generally includes computers, equipment, fixtures, furniture, inventory, machinery, supplies, vehicles, and other items in your place of business that are moveable without causing damage to themselves or the associated real property. In Texas, BPP is taxable at the same rate as real property. Most business owners significantly underestimate the complexity of BPP taxation and the opportunities for substantial savings through expert consulting.

CAD Evidence (County/Central Appraisal District Evidence)
Reviewing CAD evidence helps property owners and representatives understand the appraisal district’s position and identify whether property-specific evidence, market data, income data, cost information, or equity data may support a different valuation position.

Comparable Properties (Comps)
Properties with similar characteristics to the subject property, adjusted for any dissimilarities or differences, used to establish market value or demonstrate inequitable assessment. Comparability extends beyond location and includes age, size, style, condition, quality, use, and economic characteristics. For equity protests, comparable properties must be in the same appraisal district. For market value protests, comparable sales from broader geographic areas may be acceptable. Selecting truly comparable properties and making appropriate adjustments requires expertise and market knowledge.

Cost Approach
One of three primary appraisal methodologies used to determine property tax market valuation. The cost approach estimates the depreciated cost of reproducing or replacing the building and site improvements, then adds land value. This approach starts with replacement cost new (RCN), then deducts physical deterioration, functional obsolescence, and economic obsolescence. The cost approach is most reliable for newer properties, special-purpose properties, and properties without sufficient sales or income data. Industrial properties and business personal property are typically valued using cost approach methodology.

Customer Evidence
Documents, photographs, reports, and information provided by the property owner that may be used as evidence in the property tax protest process to support a lower property value. Effective customer evidence includes photographs showing deferred maintenance or negative influences, repair estimates, actual income and expense statements, construction cost documentation, engineer reports, environmental issues, independent appraisals, lease agreements, occupancy data, and comparable sales information. BTA’s consultants expertly identify, organize, and present customer evidence to maximize its impact during ARB hearings.
Learn More: Our Protest Process
Protest Deadline
The protest deadline is the date by which a property owner or authorized representative must file a notice of protest with the appraisal district. In many Texas cases, the deadline is May 15 or 30 days after the appraisal district mails the notice, whichever is later. Missing a deadline may limit or eliminate administrative protest options for that tax year, unless a later deadline or specific statutory procedure applies. Property owners should review the deadline printed on the notice and act early when review is needed.
Learn More: Texas Property Tax Deadlines
Equity Value (Uniform and Equal)
Equity evidence may support a protest when comparable properties appear to be appraised at lower levels under the appraisal district’s records. The strength of an equity argument depends on the property type, comparable set, appraisal district data, and applicable evidence.

Exemption
A reduction in taxable property value granted by law for qualifying properties or property owners. Common exemptions include homestead exemptions (reducing assessed value for primary residences), over-65 exemptions, disabled person exemptions, disabled veteran exemptions, agricultural exemptions, and charitable organization exemptions. Exemptions directly reduce the assessed value subject to taxation. Property owners must apply for most exemptions with their county appraisal district, and exemptions typically remain in effect once granted unless property ownership or use changes.
Learn More: General FAQs
Functional Obsolescence
Loss in value due to factors within a property that make it less desirable compared to newer properties with more modern designs, layouts, or features. Functional obsolescence includes inadequate or outdated building systems, poor floor plans, insufficient loading docks, low ceiling heights in warehouses, lack of modern amenities, or excess construction costs relative to utility. Unlike physical deterioration, functional obsolescence relates to design deficiencies rather than wear and tear. Identifying and quantifying functional obsolescence can significantly reduce property valuations, particularly for older industrial and commercial properties.

Highest and Best Use
The reasonably probable and legal use of vacant land or an improved property that is physically possible, appropriately supported, financially feasible, and results in the highest value. Highest and best use analysis considers current zoning, market demand, physical characteristics, legal restrictions, and economic feasibility. For improved properties, highest and best use may be the current use, a different use, or demolition and redevelopment. Challenging an appraisal district’s highest and best use conclusion can produce substantial value reductions when the district’s assumption doesn’t reflect market realities.
Learn More: Valuation Challenges
Informal Review (Informal Hearing)
An optional meeting between the property owner (or their representative) and an appraisal district appraiser before the formal ARB hearing. Informal reviews provide opportunities to present evidence, discuss valuation issues, and potentially reach agreement without proceeding to ARB. While informal reviews can resolve straightforward disputes, complex cases typically require formal ARB hearings where independent board members evaluate evidence. BTA consultants strategically use informal reviews when appropriate while preserving all evidence and arguments for ARB hearings when necessary.

Market Value
One of two values the appraisal district calculates to determine a property’s appraised value. Market value is defined as the price at which a property would transfer for cash or its equivalent under prevailing market conditions if exposed to the open market for a reasonable time, with both buyer and seller acting prudently, knowledgeably, and without unusual pressure. Three approaches determine market value depending on property type: income approach (income-producing properties), cost approach (industrial, special-purpose, new construction), and sales approach (residential, some commercial). Appraisal districts often overestimate market values by failing to account for property-specific issues or market conditions.

Protest (Property Tax Protest)
A property tax protest is the administrative process used to challenge certain appraisal district actions, including appraised value, classification, exemption denial, or other protestable issues. After a protest is filed, the property owner or authorized representative may present relevant evidence during informal review or an ARB hearing. The strength of a protest depends on the property facts, documentation, appraisal district records, and applicable law.
Learn More: Schedule Your Protest
Rollback Taxes
Additional taxes assessed when property receiving agricultural exemption changes to non-agricultural use. When the county appraisal district removes a property’s agricultural exemption status, it levies rollback taxes equal to the difference between taxes paid under agricultural valuation and taxes that would have been paid at market value for the previous 3 years, plus 5% annual interest. Rollback taxes frequently occur when agricultural land is sold for development. Property owners should protest agricultural land values annually to minimize potential rollback tax liability if use changes occur.
Learn More: Commercial Real Estate Services
Sales Approach (Sales Comparison Approach)
One of three primary appraisal techniques used to determine property tax market value. The sales approach compiles available data on recent sales, pending sales, and listing prices of properties comparable to the subject property. These comparable sales are adjusted for dissimilarities in location, size, age, condition, quality, and other characteristics affecting value. After adjustments, the appraiser estimates the subject property’s value through analysis of the adjusted comparable sales. The sales approach is most reliable when sufficient recent sales of truly comparable properties exist in an active market.
Tax Rate
Property owners do not control tax rates. Taxing units adopt tax rates, while appraisal districts determine appraised values. A lower final taxable value may affect the tax bill, but the actual bill depends on adopted tax rates, exemptions, and other applicable factors.
Taxable Value
Taxable value is the value used to calculate property taxes after applicable exemptions, caps, special valuations, or other adjustments are considered. A changed final appraised value may affect taxable value or the tax bill, depending on the property, exemptions, tax rates, and applicable rules.
Uniform and Equal
Uniform and equal arguments may be relevant when comparable properties appear to be appraised at lower levels. The usefulness of this evidence depends on the comparability of the properties, appraisal district records, and the facts of the protest.

Capitalization Rate (Cap Rate)
A percentage used in the income approach to convert a property’s net operating income into an estimated market value. Cap rates represent the expected rate of return on a real estate investment and vary by property type, location, condition, and market conditions. Lower cap rates indicate higher property values (investors accept lower returns for quality properties), while higher cap rates indicate lower values (investors demand higher returns for riskier properties). Appraisal districts frequently use cap rates that are too low, resulting in overvaluations. Cap rate selection is often the most contested issue in commercial property tax protests.
Learn More: Commercial Property Services
Economic Obsolescence (External Obsolescence)
Loss in property value caused by factors external to the property itself, such as changes in market conditions, neighborhood decline, increased competition, reduced demand, adverse zoning changes, environmental contamination in the area, or economic recession. Unlike physical deterioration or functional obsolescence, economic obsolescence results from forces beyond the property owner’s control. Economic obsolescence affects entire property classes or market areas simultaneously. Quantifying economic obsolescence can produce dramatic value reductions, particularly during economic downturns or when market conditions deteriorate.
Learn More: Commercial Real Estate Services
Income Approach (Income Capitalization Approach)
One of three primary techniques used to determine market value of income-producing commercial real estate for property tax purposes. This approach measures the present worth of future income benefits by capitalizing the property’s net operating income over its remaining economic life. Direct capitalization (dividing net operating income by a capitalization rate) is most common for property tax protests. Discounted cash flow analysis projects multiple years of income and expenses. The income approach is the preferred valuation method for apartments, office buildings, retail centers, hotels, and other commercial properties generating rental income.

Net Operating Income (NOI)
The annual income remaining after deducting all operating expenses from gross income, but before deducting debt service, capital expenditures, and income taxes. NOI is the fundamental measure of a commercial property’s earning power and the numerator in direct capitalization calculations (NOI ÷ Cap Rate = Value). Appraisal districts frequently understate operating expenses or overstate income, producing artificially inflated NOI and resulting overvaluations. Providing actual income and expense statements is critical evidence for commercial property protests.

Occupancy Rate
The percentage of a property’s total rentable space that is actually occupied by paying tenants. Economic occupancy (rent collected) matters more than physical occupancy (space occupied) for valuation purposes. Appraisal districts typically assume stabilized occupancy rates that exceed actual market conditions, particularly during economic downturns or in overbuilt markets. Demonstrating actual occupancy levels below district assumptions provides powerful evidence for income-based value reductions.
Learn More: Retail Property Services
Quarterly Revenue Reports
Reports that Texas hotel and short-term rental owners are legally required to submit to the State Comptroller’s Office every quarter, detailing gross revenue from room rentals. County appraisal districts access these confidential reports for hotel property tax valuations. Quarterly revenue reports provide actual income data rather than estimated income, making them powerful evidence in hotel valuation protests. BTA’s hospitality specialists understand how to analyze quarterly revenue reports and present compelling arguments for value reductions based on actual operating performance.

Freeport Exemption (Freeport Inventory Exemption)
An exemption granted under Section 11.251 of the Texas Tax Code for qualifying inventory that will be forwarded out of Texas within 175 days of acquisition or entry into Texas, or inventory in Texas for assembling, storing, manufacturing, processing, or fabricating purposes. Property owners must apply annually by April 30th. The exemption excludes oil, natural gas, and immediate petroleum derivatives. Not all Texas taxing jurisdictions offer the Freeport exemption—local voters must approve it. Businesses with significant inventory turnover should verify Freeport availability and ensure timely applications to avoid substantial tax liability on inventory.

Process Equipment (Process Manufacturing Equipment)
Specialized machinery, equipment, and systems used in manufacturing processes to transform raw materials into finished products through chemical, mechanical, or biological processes. Process equipment includes reactors, distillation columns, heat exchangers, pumps, compressors, and control systems. Process manufacturing facilities in petrochemical, refining, chemical, pharmaceutical, and food processing industries involve complex, highly specialized equipment that requires expert valuation. Appraisal districts frequently overvalue process equipment by failing to account for technological obsolescence, specialized use limitations, and removal/reinstallation costs.
Learn More: Process Manufacturing Services
Replacement Cost New (RCN)
The current cost to construct a building or improvement with equal utility using modern materials, design, and construction standards, before deducting any depreciation. RCN serves as the starting point for cost approach valuations. Unlike reproduction cost (replicating the exact property), replacement cost considers functionally equivalent modern construction. Appraisal districts frequently overstate RCN by using generalized cost manuals that don’t reflect actual construction costs for specialized industrial facilities. Providing actual construction costs, contractor estimates, or cost segregation studies can dramatically reduce RCN conclusions.

Special Purpose Property
Special purpose properties often require careful review of cost data, depreciation, functional obsolescence, economic obsolescence, market limitations, and property-specific evidence.

Book Value to Market Value Conversion Tables
Schedules used to estimate current market value when the original acquisition cost and year of asset purchase are unknown. These conversion tables apply percentage factors to depreciated book values (shown on tax returns or financial statements) to estimate market value. Different conversion factors apply to various asset categories and acquisition years. Appraisal districts provide these tables but may use aggressive conversion factors that overstate market values. Whenever possible, providing actual acquisition costs and dates produces more accurate and favorable valuations than relying on book value conversions.
Learn More: BPP Equipment Services
Cost Approach of BPP
The valuation technique used to determine business personal property market value for property tax purposes. For BPP, the cost approach estimates replacement cost new (as if the asset were purchased today), then deducts accumulated depreciation based on age, condition, and obsolescence. Unlike real property cost approach, BPP cost approach focuses on individual asset categories (computers, furniture, machinery, vehicles) rather than entire improvements. Appraisal districts use standardized depreciation schedules that may not reflect actual economic lives, technological obsolescence, or market conditions for specific assets.
Learn More: Business Personal Property Services
Depreciation (for BPP)
The reduction in value of business personal property assets due to age, use, wear and tear, technological obsolescence, and market conditions. For property tax purposes, appraisal districts apply standardized depreciation schedules (typically based on IRS Modified Accelerated Cost Recovery System guidelines with adjustments) to determine remaining value percentages for assets of different ages. These schedules vary by asset category and appraisal district. Understanding depreciation schedules and identifying opportunities to apply additional obsolescence is critical for BPP value reductions.
Learn More: BPP Valuation Services
Standardized Depreciation Tables
Schedules maintained by county appraisal districts showing the annual depreciation percentages applied to various business personal property asset categories based on acquisition year. These tables determine what percentage of original cost remains as taxable value for assets of different ages. Depreciation tables vary significantly among Texas counties—the same 10-year-old computer may be valued at 15% of cost in one county but 25% in another. Understanding your county’s depreciation tables and challenging overly aggressive schedules produces substantial BPP savings.

Foreign Trade Zone (FTZ) (Free Trade Zone)
A designated geographic area within the United States, typically near international airports or seaports, where companies can import, manufacture, store, and export raw materials, components, and finished products without paying customs duties until goods enter U.S. commerce. For property tax purposes, inventory designated as within a Foreign Trade Zone is typically exempt from Texas property taxation. Businesses operating in FTZ locations must properly document FTZ status with both customs authorities and county appraisal districts to secure property tax exemptions on qualifying inventory.
Learn More: BPP Inventory Services
Interstate Foreign Commerce (IFC)
An exemption for inventory physically located in Texas on January 1st that is not being manufactured, modified, assembled, or processed and is pre-committed for delivery to an out-of-state customer. To qualify for IFC exemption, inventory must be segregated, identified, and documented with binding sale contracts or purchase orders demonstrating the out-of-state commitment existed as of January 1st. IFC exemptions require meticulous documentation and must be claimed through the rendition process. Many businesses overlook IFC exemptions, paying unnecessary taxes on qualifying inventory.
Learn More: BPP Inventory Services
Inventory (Business Personal Property)
Goods held for sale in the ordinary course of business, raw materials, work in progress, finished goods, and supplies used in business operations. In Texas, inventory is taxable business personal property unless specifically exempted (Freeport, Foreign Trade Zone, Interstate Foreign Commerce). Inventory valuation for property tax differs from financial accounting—tax valuations use lower of cost or market on the January 1st assessment date. Businesses with significant inventory should explore all available exemptions and ensure accurate inventory reporting to minimize tax liability.
Learn More: BPP Inventory Services
Life/Class/Year (LCY) Method
A business personal property reporting methodology that organizes assets by economic life, asset class, and year of acquisition. The LCY method provides appraisal districts with detailed asset information enabling more accurate depreciation calculations. While LCY reporting requires more effort than simpler methods, it often produces lower valuations by precisely matching assets to appropriate depreciation schedules. BTA’s BPP specialists utilize the LCY method strategically, providing sufficient detail to support lower values while avoiding over-disclosure that could increase assessments.
Learn More: BPP Equipment Services
Net Book Value (NBV)
A business’s asset value calculated as original cost minus accumulated depreciation as shown on financial statements or tax returns. Net book value reflects accounting depreciation (typically accelerated for tax purposes) rather than actual market value. Appraisal districts may request financial statements showing net book values, then apply conversion factors to estimate market values. Because accounting depreciation often exceeds economic depreciation, providing actual acquisition costs and years typically produces more favorable tax valuations than allowing districts to convert from net book values.
Learn More: BPP Valuation Services
New Age Mix (Age Mix Adjustment)
An obsolescence factor applied by some appraisal districts when most assets within a category have recent acquisition dates, meaning the age mix is “out of balance” with primarily newer assets. This adjustment compensates for lack of older, heavily depreciated assets in the asset mix. The new age mix schedule typically does not apply to vehicles. Understanding when new age mix adjustments apply—and when they should not apply—requires expertise in BPP valuation methodologies and can prevent overvaluations of businesses that have invested in new equipment.

Rendition
A rendition is a report filed with an appraisal district identifying certain taxable business personal property owned or controlled on January 1. For many Texas BPP accounts, the common rendition deadline is April 15, though some property types, extensions, or special rules may differ. Rendition records may include asset categories, acquisition costs, acquisition years, inventory information, and business location details. Accurate, documented reporting helps support later appraisal review when needed.
Learn More: BPP Services Overview
Year of Acquisition
The calendar year when a business personal property asset was purchased and placed in service. Year of acquisition determines which depreciation schedule and remaining value percentage applies to each asset. Appraisal districts use year of acquisition to calculate current taxable values by applying age-based depreciation to original costs. Accurate reporting of acquisition years is essential—errors can cause significant over- or under-valuations. When acquisition years are unknown, book value conversion methods estimate values, typically less favorably than actual cost and year reporting.

Arbitration Hearing (Binding Arbitration)
A post-ARB appeal option available to property owners unsatisfied with appraisal review board hearing results. Arbitration is filed with the Texas Comptroller’s Office, which provides a list of qualified arbitrators. Both parties select an arbitrator who conducts a hearing and issues a binding decision that cannot be appealed by either party. Arbitration offers a faster, less expensive alternative to judicial appeals for properties valued under $5 million. The arbitrator’s decision is final and binding on both the property owner and the appraisal district. Filing deadlines and deposit requirements apply.

District Court Appeal (Judicial Appeal)
District court appeals are post-ARB legal proceedings. Availability, deadlines, procedures, and legal strategy depend on the property, issue, value, and applicable law. Property owners should consult qualified legal counsel for legal advice. BTA may support valuation documentation and property-specific evidence review when appropriate.
Learn More: Litigation & Arbitration Services
Judicial Appeal
A judicial appeal is a post-ARB legal proceeding filed in district court when a property owner seeks further review of an ARB order. Availability, deadlines, procedure, and legal strategy depend on the property, issue, value, and applicable law. Property owners should consult qualified legal counsel for legal advice.
Learn More: Post-ARB Appeal Options
Manage Litigation Appeal (Litigation Management)
BTA may support post-ARB matters by helping organize valuation evidence, appraisal records, and property-specific documentation in coordination with qualified legal counsel when appropriate. BTA is not a law firm and does not provide legal advice.
Learn More: Litigation & Arbitration Services
Summary Judgment
A legal ruling by a district court judge deciding a case without a full trial when there are no disputed material facts and one party is entitled to judgment as a matter of law. In property tax litigation, summary judgment motions argue that the appraisal district’s valuation methodology was legally flawed, the ARB violated procedural requirements, or undisputed evidence establishes the correct value. Summary judgments resolve cases faster and less expensively than full trials. Both property owners and appraisal districts may seek summary judgment, making early case evaluation and strong evidence development critical.
