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

By StartBusinessByState·Publisher: Robert Smith·Research process

Last updated: November 3, 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, statutory liability insurance minimums, fingerprint-based background checks, and ongoing compliance audits.

Recording law is a separate compliance issue. Texas Penal Code §16.02 provides a defense for a participant’s recording or an interception made with a participant’s prior consent, subject to the statute’s conditions. It does not authorize trespass, unlawful access or every surveillance technique, and a client’s instruction is not consent from a participant unless the client actually is one. Multistate and federal rules can also apply. Have the proposed method reviewed before using it.

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

Step 1: Meet the Company Representative Experience Requirement

Each company must have a qualified company representative. For an investigations company, DPS lists these qualifying routes under the Act and Rule 35.121:

• Three consecutive years of investigation-related experience.
• A bachelor’s degree in criminal justice or a related course of study.
• A bachelor’s degree plus 12 months of investigation-related experience.
• An associate degree in criminal justice or a related field plus 24 months of investigation-related experience.
• A qualifying specialized program of at least 200 instructional hours affiliated with an accredited four-year college or university, endorsed by its criminal-justice department and including its faculty. DPS may accept other combinations at its discretion.

Experience must satisfy DPS’s investigation-related requirement. A job title, military service or law-enforcement employment does not by itself prove qualification. Document dates, duties and responsibilities using the application instructions.

• Identify the investigations actually performed and the dates of work.
• Provide the degree or specialized-program evidence for the route claimed.
• For combined services, confirm whether additional qualified representatives are necessary.

Submit the supporting evidence DPS requests. The representative’s role and company relationship must also meet Rule 35.41; using the phrase “qualified manager” does not establish eligibility.

Step 2: Pass the DPS PSB Company Representative Examination

Schedule the company representative examination after following DPS’s application instructions. The open-book test covers Chapter 1702 and Chapter 35 as they apply to managing a licensed company.

• 50 true/false and multiple-choice questions in two hours.
• Passing score: at least 70%.
• Bring government-issued identification, the printed statutes/rules and the supplies DPS specifies.
• One examination is included with the original fee; each reexamination costs $100.

DPS requires a passing score of at least 70%; use its current statutes, rules and examination instructions to prepare. Optional resources include PSB Manager Prep and TALI materials; verify their current content against the official examination instructions before purchasing.

Step 3: Choose the Structure and Obtain Required Insurance

If you choose an LLC, its Certificate of Formation costs $300. An LLC is optional and does not replace the company license. Section 1702.124 sets liability minimums of $100,000 per occurrence for bodily injury/property damage, $50,000 per occurrence for personal injury, and $200,000 total aggregate. Coverage must address the licensed business activities. Clients can demand higher limits; obtain quotes for general liability and any needed professional liability instead of assuming a fixed premium.

Examples of exposures to discuss with your insurer, not a ranked claim-frequency survey:

• 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. Under Rule 35.27, failure to keep evidence of current coverage on file results in suspension effective on receipt of the notice. Keep coverage and the DPS filing current; a lapse or missing continuity evidence can require an approved reinstatement application.

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

Class	Scope	Application Fee	Best For
Class A	Private investigations	$361	Investigation services; personal protection is a separate regulated activity
Class B	Security services contractor	$412	Applicable approved security-service categories
Class C	Combined investigation and security	$556	Each regulated service needs its applicable qualifications

Submit the company license application packet:

• Submit the company application and required fees through TOPS.
• Provide the required liability evidence and company representative qualifications.
• Complete fingerprints and background checks for the applicant and required principals under §1702.110, including the overseeing officers and partners/shareholders with at least 25% interests.
• Provide legal-structure records and the individualized checklist documents.
• Provide the federal-benefit eligibility documentation required by the rules effective July 2, 2026; follow DPS’s accepted-document list.

DPS review depends on a complete application, required documents and background checks. Confirm the application status before committing to an opening date. Company licenses last one year. Individual investigator licenses last two years. Calendar each expiration separately.

Step 5: License Each Individual Investigator

Each investigator needs the appropriate individual license and company affiliation. DPS lists $37 for the investigator license, with fingerprint charges separate. Applicants must meet the statutory eligibility and background-check requirements; an individual PI application does not require the company representative’s examination or a universal initial PI course.

• Be at least 18 and meet the Act’s eligibility criteria.
• Complete the fingerprint/background-check process and required application documents.
• Maintain affiliation with a licensed company.
• Complete PI continuing education before renewal: 18 hours for less than 15 years of continuous PI licensure; 12 hours for more than 15 years. Both include two ethics hours and two Act/rules hours. Confirm the renewal classification with DPS at the boundary.

Do not substitute an informal “trainee” arrangement for licensing. Follow DPS’s individual-application and working-before-licensure instructions; the company representative’s experience routes are separate from an employee PI’s application.

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

The Comptroller classifies investigative and detective services as taxable security services. Obtain the free Sales and Use Tax Permit and collect state plus applicable local sales tax on the taxable total, including reimbursed expenses when included in that service. The combined rate can reach 8.25%; use the applicable sourcing rules and rate lookup rather than one universal rate.

Keep a valid exemption or resale certificate when applicable. A customer’s government connection or an attorney’s statement that work is for an exempt client does not automatically exempt your sale. Apply the Comptroller’s documentation and resale rules to the actual transaction.

File on the frequency the Comptroller assigns. Monthly and quarterly reports generally fall due on the 20th after the reporting period; do not assume every PI is a monthly filer. Track the due date shown in your tax account.

Step 7: Separate Handgun Carry from Personal-Protection Licensing

A Texas PI who is not providing security or personal-protection services may carry a handgun subject to Penal Code Chapter 46 and other restrictions; DPS does not impose a universal LTC requirement for that work. A PI license itself grants no exemption from weapons law. If choosing an LTC, the standard application fee is $40, with training and other applicable costs separate. See dps.texas.gov/section/handgun-licensing.

Permitless-carry provisions do not override private-security requirements. Noncommissioned security officers may not carry on duty. DPS also prohibits a PI from openly carrying a handgun while executing a capias or arrest warrant. An LTC does not grant general permission to enter federal buildings with a firearm.

Bodyguard and executive-protection work requires the applicable company authority and individual Personal Protection Officer license. Applicants must be at least 21, hold or concurrently apply for a security officer commission, complete approved training and the required psychological evaluation. An investigation license or LTC alone does not authorize these services. Follow the current DPS requirements before accepting that work.

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

Section 16.02 contains a defense for a party to the communication or a person acting with a party’s prior consent, subject to the statute’s unlawful-purpose limitation. Consent, privacy, location and other laws still matter. A nonparticipant can sometimes rely on a participant’s valid prior consent; merely being physically present does not itself make you a participant.

What this means operationally:

• Confirm who is a party and who has given legally effective consent.
• Have the recording method, location and intended use checked before collection.
• Preserve consent and evidence-handling records without assuming consent resolves every privacy issue.

What this does NOT permit:

• Intercepting communications without a valid legal basis.
• Trespass, unauthorized system access or other unlawful conduct to obtain a recording.
• Assuming Texas consent rules control a multistate communication or guarantee admissibility in court.

Interception offenses under §16.02 are generally second-degree felonies, with separate state-jail provisions for specified conduct. Federal law and other states’ rules may also apply. Avoid treating a simplified “one-party state” label as permission for a specific investigation.

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. Assess insurer contracting requirements and actual demand before relying on this niche.
• Corporate investigations: Pre-employment background, workplace investigations, IP theft, embezzlement. Set fees from your costs, scope and market evidence; no universal hourly range is established here.
• Litigation support: Witness location, asset location, statement collection, evidence preservation for attorneys. Confirm demand through actual prospective clients rather than assuming a steady caseload.
• Skip tracing: Locating debtors, missing persons, witnesses for civil actions. Check lawful database access, client authorization and the economics of each assignment.
• Executive protection / armed bodyguard: Requires the applicable personal-protection company and individual authorizations; an LTC alone is insufficient. Do not assume a particular revenue level.
• Cybercrime / digital forensics: Assess specialized skills, lawful access and tools before offering this service.
• Cross-border investigations: Texas-Mexico border work for Texas clients with binational interests.

Frequently Asked Questions

What license do I need to start a private investigation business in Texas?

A Class A company license covers investigations; a Class C license combines approved investigation and security services. DPS lists $361 for Class A and $556 for Class C, with annual company renewal. Each investigator also needs the individual license and company affiliation; that license has a two-year term.

What experience do I need to be a Company Representative for a Texas PI agency?

DPS accepts three consecutive years of investigation-related experience; a criminal-justice or related bachelor’s degree; another bachelor’s plus 12 months of investigation experience; a criminal-justice or related associate degree plus 24 months; or a qualifying 200-hour university-affiliated specialized program. Other combinations are discretionary. The representative must also satisfy the company relationship and examination requirements.

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

Texas §16.02 recognizes a participant/prior-participant-consent defense subject to its conditions, including the unlawful-purpose limitation. It is not limited to a recorder who personally participates, and it is not permission for trespass or every surveillance method. Federal and other states’ laws may also apply; obtain case-specific legal review.

Are private investigation services taxable in Texas?

Investigative and detective services are generally taxable. Collect state and applicable local tax on the total taxable charge unless the purchaser supplies a valid exemption or resale certificate. Use the assigned filing frequency and applicable rate rather than assuming every job is taxed at 8.25% or every PI files monthly.

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

Not in every case. DPS says a PI who is not providing security or personal-protection services may carry subject to Penal Code Chapter 46. The PI credential grants no special weapons exemption. Security and personal-protection work have separate company, commission and individual-license requirements; an LTC alone does not satisfy them.

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

Get an insurer’s quote for your actual services, limits, record and exposures. The statutory company minimum is $100,000 bodily injury/property damage per occurrence, $50,000 personal injury per occurrence and $200,000 aggregate, not $1 million. A client may require more. General liability and professional liability are distinct; a quoted price or certificate does not itself establish coverage.

How much does it cost to start a PI business in Texas?

Startup costs depend on the services, equipment and working cash your business needs. DPS lists $361 for a Class A company license and $37 for an individual PI license, with fingerprint and other applicable costs separate. Add $300 only if you choose a Texas LLC, then obtain insurance, equipment, database, software and workspace quotes and a working-cash reserve. TALI active dues are $175 annually if you join.
