How to Start a Private Investigation Business in Texas (2026)

Texas’s private investigation industry is licensed and regulated by the Texas Department of Public Safety Private Security Bureau (DPS PSB) under Texas Occupations Code Chapter 1702. The structure is built around three company license classes: Class A for Investigations Companies, Class B for Security Contractors (alarm installation, security guards, armored car, locksmiths), and Class C for combined investigation and security services. A first-time PI agency operator typically chooses Class A or Class C depending on whether they plan to also offer security services. The DPS PSB framework is one of the more comprehensive PI regulatory regimes in the US, with mandatory company licensing, manager qualifications, individual licensing for every investigator, $1M liability insurance minimum, fingerprint-based background checks, and ongoing compliance audits.

The other big Texas-specific consideration is recording law. Texas is a one-party consent state under Texas Penal Code § 16.02 – one of the more permissive recording-law states, similar to North Carolina, Illinois, and federal law. As long as you’re a party to the conversation, you can record it without informing the other parties. Compare this to two-party consent states (Pennsylvania, Massachusetts, California, Florida, Washington) where every party must consent or be notified. For a Texas PI doing surveillance, undercover work, or sworn statements, this dramatically expands the practical evidence-gathering toolkit. Unlawful interception by a non-party in Texas is a second-degree felony (2-20 years + $10,000) under § 16.02 – the legal stakes are real, but the one-party rule is operationally favorable. This guide compiles the specific DPS PSB licensing, recording law, License to Carry, sales tax (PI services taxable in Texas), and TX-specific operational considerations that apply to starting a PI business in Texas in 2026.

How to Start a PI Business in Texas (Step by Step)

Step 1: Meet the Qualified Manager Experience Requirement

Texas DPS PSB requires every Class A/B/C company license to have a designated Qualified Manager who has met specific experience requirements under Texas Occupations Code Chapter 1702. Experience pathways:

• Pathway A: 3 consecutive years of investigation-related experience (minimum 5,000 hours documented)
• Pathway B: Bachelor’s degree in criminal justice or related field + 6 months investigation experience
• Pathway C: Associate’s degree in criminal justice + 12 months investigation experience
• Pathway D: Specialized 200+ hour investigative training course through an accredited college

Qualifying experience generally includes:

• Texas DPS or other law enforcement (rank above patrolman for sworn time)
• Federal investigative service (FBI, DEA, HSI, ATF, USSS, etc.)
• Military criminal investigative service (CID, NCIS, OSI, CGIS)
• Insurance Special Investigations Unit (SIU)
• Attorney-employed investigator (paralegal investigator role)
• Texas-licensed PI agency employee under direct supervision of a licensed PI

Document your experience with notarized letters from prior supervisors detailing your role, dates, and types of investigations conducted. DPS PSB scrutinizes experience claims – vague letters and unverifiable employment history are common rejection reasons.

Step 2: Pass the DPS PSB Qualified Manager Examination

Schedule the Manager’s Examination through Texas DPS PSB. The exam covers:

• Texas Occupations Code Chapter 1702
• 37 TAC Chapter 35 administrative rules
• Evidence collection and chain of custody
• Ethics and standards of conduct
• Texas Penal Code § 16.02 (recording law)
• Surveillance protocols and stalking statute boundaries
• Business operations and licensing compliance
• Texas False Imprisonment, Trespass, and related statutes that bound surveillance

Pass rate is around 60-70% on first attempt. Resources: PSB Manager Prep, the DPS PSB Statutes and Rules Book, and TALI’s training materials. Plan 40-80 hours of study.

Step 3: Form Your Texas LLC and Obtain $1M Liability Insurance

File Certificate of Formation Form 205 with the Texas Secretary of State for $300. Get $1M per occurrence / $2M aggregate general liability insurance – this is the DPS PSB minimum for company licensure. Typical premium runs $1,000-$3,000/year for a small PI operation. Many carriers also require errors and omissions (E&O) coverage at additional cost ($800-$2,500/year for $1M E&O).

Common claims against PI operations:

• Invasion of privacy / stalking accusations from surveillance subjects
• Defamation or false light from investigation reports
• Negligent investigation claims from clients
• Unauthorized recording / wiretap allegations
• Trespass during surveillance operations

Submit certificate of insurance with your company license application. Lapse in coverage triggers automatic license suspension – maintain continuous coverage as a top priority.

Step 4: Submit Class A or Class C Company License Application

Class	Scope	Application Fee	Best For
Class A	Private Investigations only	~$400	Pure PI operations – infidelity, fraud, custody, executive protection (without security guard work), corporate investigations
Class B	Security Contractor only – guards, alarms, armored car, locksmiths	$400	Pure security guard or alarm operations
Class C	Combined Investigation + Security	$556	Hybrid operations – investigation services + security guard / alarm services

Submit the company license application packet:

• Completed application (PSP-67 or equivalent current form)
• Certificate of insurance ($1M GL minimum)
• Qualified Manager experience documentation
• Fingerprint cards for manager + every officer/director/owner with 25%+ stake
• Corporate structure documentation (LLC, corp, partnership)
• Bond if applicable
• Application fee

DPS PSB processes typical applications in 4-12 weeks. License is valid 2 years; renew before expiration to avoid lapse.

Step 5: License Each Individual Investigator

Every PI working under your company license must hold an individual investigator license through DPS PSB. Costs $25-$50 application per investigator + fingerprint-based background check. Each PI must:

• Be at least 18 years old
• Have no disqualifying convictions (most felonies, certain misdemeanors)
• Pass FBI + Texas DPS fingerprint background
• Complete required initial training
• Maintain ongoing CEUs (currently 8 CEUs every 2 years)

Trainee pathway: New investigators with limited experience can work as a trainee under direct supervision of a fully licensed PI for a structured period before being eligible for unsupervised licensure. This is how most operators bring new investigators online.

Step 6: Register for Sales Tax – PI Services Are Taxable in Texas

Per the Texas Comptroller, investigation and security services are taxable in Texas at the full state-plus-local sales tax rate. Register for a free Sales and Use Tax Permit. Collect 8.25% combined sales tax on PI services performed in Houston, Dallas, Austin, San Antonio, Fort Worth, and El Paso.

Government clients (federal, state, county, city, school districts, public hospitals) are typically exempt – obtain their tax exemption certificate before omitting tax. Insurance company SIU clients are NOT exempt. Attorney clients are not exempt unless billing the work pass-through to a tax-exempt government end client.

Sales tax remittance is due monthly (typically by the 20th of the following month) for most PI operations. The Comptroller assigns filing frequency based on volume. The Texas Association of Licensed Investigators (TALI) provides specific guidance to members on sales tax compliance for PI work.

Step 7: Get License to Carry (LTC) and PPO Endorsement if Armed

Texas License to Carry (LTC) is required to carry a concealed handgun in Texas, including for PI work. Apply through DPS at dps.texas.gov/section/handgun-licensing. Cost: $40 application + 4-6 hour training course (~$80-$150) + range qualification. Valid 5 years. Background check + fingerprint required.

Note: Texas allows permitless carry under Texas Government Code § 411.180 (HB 1927 of 2021) for adults 21+ who are not otherwise prohibited from possessing a firearm. However, PIs typically still maintain LTC because it provides reciprocity with other states, simplifies federal building access, and is preferred by clients who care about formal credentialing.

Personal Protection Officer (PPO) endorsement is a separate DPS PSB endorsement on a Class A or Class C license required for armed bodyguard / executive protection work. Higher training requirements, additional fee per officer, and specific firearms qualification. Most pure PI operations don’t need PPO unless they offer armed personal-security services.

Step 8: Operate Under Texas Penal Code § 16.02 (One-Party Consent Recording)

Texas is a one-party consent recording state under Texas Penal Code § 16.02. A wire, oral, or electronic communication can be lawfully intercepted if you are a party to the communication or if one of the parties has given prior consent to the interception. As long as you’re a party to the conversation, you can record without informing the other parties.

What this means operationally:

• You can record your own undercover conversations with subjects
• Your client can record their own conversations and provide them to you
• You can record sworn statements with witness consent (the witness is a party)
• You can use audio recording during surveillance when you are present and a party to the conversation

What this does NOT permit:

• Wiretapping or planting recording devices in places where you’re not present (this is a non-party interception, second-degree felony under § 16.02 – 2-20 years + $10,000)
• Recording conversations in places where parties have a reasonable expectation of privacy without consent (changing rooms, restrooms, private homes you don’t occupy)
• Federal court use – federal Wiretap Act has additional restrictions

Compared to two-party consent states (Pennsylvania, Massachusetts, California, Florida, Washington, and several others), Texas’s one-party rule meaningfully expands the practical evidence-gathering toolkit. PIs who operate in multiple states must track which state’s law applies to each recording (typically the state where the recording occurs, but multi-state communications create complexity).

Texas PI Service Niches Worth Considering

• Domestic and family law: Infidelity surveillance, custody investigations, hidden assets. Drives the residential PI market.
• Insurance Special Investigations Unit (SIU): Workers’ comp fraud, auto accident fraud, bodily injury fraud. Steady contract revenue with major Texas insurers.
• Corporate investigations: Pre-employment background, workplace investigations, IP theft, embezzlement. Higher hourly rates ($150-$350/hour).
• Litigation support: Witness location, asset location, statement collection, evidence preservation for attorneys. Texas’s plaintiffs’ bar is large and provides steady demand.
• Skip tracing: Locating debtors, missing persons, witnesses for civil actions. Lower per-job rates but high volume.
• Executive protection / armed bodyguard: Requires PPO endorsement + LTC. High-revenue work for high-net-worth Texas clients (Houston energy executives, DFW corporate, Austin tech).
• Cybercrime / digital forensics: Growing niche; specialized training and tools required.
• Cross-border investigations: Texas-Mexico border work for Texas clients with binational interests.

Is Texas a one-party or two-party consent recording state?

One-party consent under Texas Penal Code § 16.02. As long as you are a party to the conversation, you can record without informing the other parties. This is one of the more permissive recording-law states (similar to NC, IL, and federal law). Compare to two-party consent states (Pennsylvania, Massachusetts, California, Florida, Washington) where every party must consent. Unlawful interception by a non-party in Texas is a second-degree felony (2-20 years + $10,000), so the one-party rule applies only when you’re actually a party to the communication.

Are private investigation services taxable in Texas?

Yes. Investigation services and security services are taxable in Texas at the full state-plus-local sales tax rate (8.25% combined in major cities). Register for a free Sales and Use Tax Permit from the Texas Comptroller. Government clients are typically exempt; insurance SIU clients are not. Sales tax remittance is due monthly (by the 20th of the following month) for most PI operations.

Do I need a separate License to Carry for armed PI work in Texas?

Yes – the Texas License to Carry (LTC) is separate from the DPS PSB PI license. Apply through DPS for $40 + 4-6 hour training course (~$80-$150) + range qualification. Valid 5 years. For armed bodyguard / executive protection work, you also need DPS PSB Personal Protection Officer (PPO) endorsement on your Class A or Class C license – higher training and a separate fee per officer. Note: Texas allows permitless carry (HB 1927 of 2021), but PIs typically still maintain LTC for reciprocity with other states and credentialing.

How much does $1M general liability insurance cost for a Texas PI agency?

Typical premium for a small PI operation runs $1,000-$3,000/year for $1M per occurrence / $2M aggregate general liability. Many carriers also recommend errors and omissions (E&O) coverage at additional cost ($800-$2,500/year for $1M E&O). Common claims: invasion of privacy from surveillance subjects, defamation/false light from investigation reports, negligent investigation, unauthorized recording allegations, trespass during surveillance. Submit certificate of insurance with your DPS PSB company license application – lapse triggers automatic license suspension.
