Taiwan Recording Laws: One-Party Consent Rules and Penalties (2026)

Overview of Taiwan's Recording Consent Framework

Taiwan operates under a one-party consent standard for recording conversations. Under the Communication Security and Surveillance Act (通訊保障及監察法, commonly abbreviated as the CSSA), a person who is a party to a communication may lawfully record that communication without notifying the other participants.

The governing provision is Article 29 of the CSSA. It states that surveillance conducted by a party to the communication, or with the consent of one party to the communication, does not constitute a criminal offense under the Act, provided the conduct is not carried out for an illegal purpose.

This means that in Taiwan, if you are participating in a phone call, video call, or in-person conversation, you may record that interaction without asking for or receiving permission from anyone else in the conversation. The sole condition is that your purpose for recording must be lawful.

The CSSA was originally enacted on July 14, 1999, and has been amended multiple times, most recently in 2024 with significant anti-fraud provisions. It serves as Taiwan's primary statute governing both private recording rights and government surveillance authority.

The Communication Security and Surveillance Act (CSSA)

The CSSA was enacted to protect the freedom and privacy of communications while establishing a legal framework for lawful surveillance when necessary for national security and social order. Article 1 states that communication surveillance may only be conducted when necessary and must not exceed the minimum level of intrusion needed to achieve its objective.

Definition of Communications

The CSSA defines "communications" broadly. Article 3 covers:

• Wired and wireless telecommunications, including sending, storing, transmitting, or receiving symbols, text, images, sound, or other information
• Mail and letters
• Speeches and conversations

This broad definition means the one-party consent rule applies to phone calls, text messages, emails, video conferences, messaging apps, and face-to-face conversations alike.

Article 29: The One-Party Consent Exception

Article 29 is the provision that establishes Taiwan's one-party consent standard. Under this article, recording is not a criminal offense when:

1. The person conducting the recording is one of the parties to the communication
2. The person has obtained consent from at least one party to the communication
3. The recording is not conducted for an illegal purpose

All three conditions of the first or second scenario, combined with the third, must be met. The "not for an illegal purpose" requirement means that recording a conversation to facilitate blackmail, extortion, or another crime would strip away the legal protection. Recording to preserve evidence of wrongdoing, document a business agreement, or protect your own legal interests is lawful.

Court-Ordered Wiretapping Under the CSSA

While private individuals benefit from one-party consent, government surveillance of communications requires judicial authorization under the CSSA. The requirements are strict and carry significant procedural safeguards.

Article 5: Qualifying Offenses

Court-ordered communication surveillance is available only for serious criminal offenses. Article 5, Paragraph 1 requires that the offense under investigation carry a minimum penalty of three years' fixed-term imprisonment. The article also lists specific qualifying offenses that meet this threshold.

Common qualifying offenses include serious drug trafficking, organized crime, corruption, and offenses against national security. Prosecutors must demonstrate that the surveillance is necessary and that less intrusive investigative methods are insufficient.

Article 7: Reporting and Oversight

Article 7 establishes mandatory reporting obligations. When court-authorized surveillance concludes, the enforcement agency must report to the prosecutor or the overseeing national intelligence authority, who then reports to the court. The report must include:

• The name and address of the person under surveillance
• The applicable legal provision under Article 11, Paragraph 1
• The warrant reference number
• The actual period of surveillance
• Whether communications relevant to the investigation's purpose were obtained
• Information about the remedy procedure available to the surveillance subject

Article 11-1: Network Traffic Records (2024 Amendment)

The 2024 amendments to the CSSA, passed on July 12, 2024, as part of Taiwan's broader anti-fraud legislative package, added Article 11-1. This new provision establishes regulations for law enforcement to access network traffic records during investigations into modern cybercrimes and fraud.

The amendment also revised Articles 14 and 14-1 to impose explicit obligations on telecommunications enterprises and public telecommunications network operators to assist in enforcing communication surveillance orders and to retain subscriber data, communication records, and network traffic records.

Criminal Code Privacy Protections: Articles 315-1 and 315-2

In addition to the CSSA, Taiwan's Criminal Code contains provisions that protect against unauthorized recording and eavesdropping. Articles 315-1 and 315-2 were added to the Criminal Code in 1999 to address privacy violations involving modern technology.

Article 315-1: Eavesdropping and Secret Recording

Article 315-1 makes it a criminal offense to, without justification:

• Use devices or equipment to peek at, wiretap, or eavesdrop on the conversations of others
• Record, photograph, or videotape the private activities or speeches of others

The penalty is imprisonment for up to three years, detention, or a fine of up to NT$30,000.

The key phrase is "without justification." A person who records their own conversation has justification because they are a party to the communication and are exercising their rights under Article 29 of the CSSA. Article 315-1 targets third-party eavesdroppers and those who record private activities in which they have no part.

Article 315-2: Distribution and Profit

Article 315-2 addresses the distribution or commercial exploitation of recordings obtained in violation of Article 315-1. A person who, for profit, furnishes a location, devices, or equipment to facilitate eavesdropping or secret recording faces criminal penalties.

This provision was motivated by growing concerns about voyeurism and the commercial distribution of secretly captured material. It adds a layer of deterrence beyond the initial act of recording.

CSSA Penalties for Illegal Surveillance

The CSSA imposes its own set of criminal penalties, separate from and in addition to those in the Criminal Code.

Article 24: Unauthorized Surveillance

Any person who illegally monitors the communications of another person faces imprisonment for up to five years.

For civil servants or employees who conduct or assist with communication surveillance and abuse the power, opportunity, or means entrusted to them through their duties, the penalty is six months to five years imprisonment.

When the illegal surveillance is conducted with the intention of making a profit, the penalty increases to one to seven years imprisonment.

Article 25: Leaking Surveillance Information

Non-civil servants who become aware of secret information through their duties related to lawful surveillance and who leak or disclose that information without good cause face imprisonment for up to two years, detention, or a fine of up to NT$20,000.

Article 28: Illegally Obtained Information

Persons who knowingly leak or distribute communication surveillance information that was obtained illegally face imprisonment for up to three years.

Complaint-Based Prosecution

Under the CSSA, the offenses in Article 24, Paragraph 1 and Article 25, Paragraph 1 are prosecutable only upon receiving a formal complaint from the affected party. This means that the person whose communications were illegally recorded must file a complaint before the prosecution can proceed.

Recording Phone Calls in Taiwan

Taiwan's one-party consent rule applies fully to phone calls. If you are a participant in a telephone conversation, you may record it without informing the other party. This applies to calls made on landlines, mobile phones, and internet-based calling platforms such as LINE, WhatsApp, or FaceTime.

The recording must not be for an illegal purpose. Recording a phone call to preserve evidence of a business deal, document a verbal agreement, or protect yourself in a dispute is lawful. Recording a call to facilitate extortion or blackmail removes the legal protection.

Third-party interception of phone calls without court authorization is a criminal offense under both the CSSA and the Criminal Code.

Recording In-Person Conversations

The same one-party consent principle governs in-person conversations. A participant in a face-to-face discussion may record it without the knowledge or consent of others present.

However, Article 315-1 of the Criminal Code draws a boundary. Recording the private conversations or activities of others when you are not a participant and have no justification is a criminal offense. Placing a hidden recording device in someone's home, office, or vehicle to capture conversations you are not part of falls squarely within the prohibition.

The distinction is clear: participants may record; non-participants generally may not.

Recording in Public Places

Taiwan does not have a comprehensive national law governing recording or surveillance cameras in public spaces. The legal framework is composed of several overlapping provisions.

Police authorities may install surveillance cameras in public areas under Article 10 of the Police Authority Enforcement Act, particularly in locations identified as crime hotspots. The National Police Agency has invested in public camera infrastructure across the island.

For private individuals, recording in a genuinely public space where there is no reasonable expectation of privacy is generally permissible. Street scenes, public parks, and open commercial areas do not carry the same privacy protections as private homes or closed offices.

The boundaries become less clear in semi-public spaces such as apartment building common areas, building lobbies, and shared facilities. Whether a particular area carries a reasonable expectation of privacy is assessed on a case-by-case basis by courts, and disputes over camera placement in shared residential spaces are common.

Management of civilian and community surveillance systems remains largely unregulated by specific statutory law, though the Personal Data Protection Act applies when recorded footage can identify individuals.

Workplace Recording and Employee Monitoring

Taiwan's labor laws do not contain a specific statute addressing workplace recording. The legal framework is assembled from the CSSA, the Criminal Code, and the Personal Data Protection Act (PDPA).

Employee Recording of Conversations

An employee who participates in a workplace conversation may record it under the one-party consent rule. This includes meetings with supervisors, discussions about employment terms, and conversations with coworkers where the employee is a participant. Such recordings can serve as evidence in labor disputes, harassment complaints, or wrongful termination cases.

Employer Monitoring

Employers may monitor workplace communications and install surveillance cameras, but must comply with the PDPA. If surveillance footage or audio recordings can directly or indirectly identify a natural person, the data qualifies as personal data under the PDPA.

Employers are required to:

• Clearly communicate to employees the purpose of data collection and how the information will be used
• Limit the use of surveillance data to the necessary scope of the stated purpose
• Ensure the monitoring has a legitimate and reasonable connection to the purpose of collection

Taiwan courts evaluate employer monitoring by examining whether employees had a reasonable expectation of privacy in the monitored context and whether the monitoring was proportionate to the employer's legitimate interests.

2025 PDPA Amendments

On November 11, 2025, amendments to the PDPA were officially promulgated. The amendments establish the Personal Data Protection Commission (PDPC) as a dedicated regulatory authority and introduce new data breach notification requirements. These changes strengthen the compliance obligations for employers who collect personal data through workplace monitoring, including video and audio surveillance.

Business Compliance Considerations

Businesses operating in Taiwan that record communications should follow these guidelines.

Identify your legal basis. Determine whether recordings are collected under one-party consent (employee or agent is a participant), customer consent (disclosed call recording), or another lawful basis under the PDPA.

Provide notice when recording non-participants. While one-party consent allows a participant to record, businesses that routinely record customer calls should consider providing notice to support PDPA transparency obligations and reduce legal risk.

Define retention periods. Establish clear policies for how long recordings are stored. The PDPA requires that personal data not be retained longer than necessary for the purpose of collection.

Restrict access. Limit access to recorded communications to authorized personnel. Maintain access logs and audit trails.

Train employees. Staff who handle recordings should understand the boundaries of lawful recording, including the prohibition on recording for illegal purposes and the PDPA requirements for handling personal data.

Address cross-border transfers. If recordings are stored or processed outside Taiwan, the transfer must comply with the PDPA's cross-border transfer provisions. The PDPA includes specific restrictions on transferring personal data to mainland China.

Cross-Strait Considerations

Taiwan maintains specific legal restrictions on data transfers to mainland China. The PDPA and related regulations prohibit certain categories of personal data from being transferred across the Taiwan Strait. Communications enterprises, social work offices, and human resource agencies are specifically prohibited from transferring subscriber or client personal data to China.

These restrictions are relevant for multinational businesses that operate across both jurisdictions. Recordings made in Taiwan that contain personal data of Taiwanese citizens may be subject to cross-border transfer restrictions if the business intends to process or store the recordings on the mainland.

The legal frameworks governing surveillance and privacy in Taiwan and mainland China differ fundamentally. Taiwan's CSSA provides judicial oversight of government surveillance and protects individual privacy through court authorization requirements. Mainland China's surveillance framework permits broader government access to personal data with fewer judicial safeguards.

Admissibility of Recordings as Evidence

Recordings made under one-party consent are generally admissible as evidence in Taiwanese courts. The Code of Criminal Procedure requires courts to assess the admissibility of evidence through a comprehensive evaluation that considers the spirit of the Constitution, the severity of any procedural violations, and the nature of the alleged crime.

The 2014 amendments to the CSSA strengthened the exclusionary rule for surveillance evidence. Content acquired through illegal surveillance is not admissible in court proceedings. Likewise, content from lawful surveillance that is unrelated to the stated purpose of the surveillance must be excluded.

For private recordings made under one-party consent, the key factors are whether the person was genuinely a party to the communication and whether the recording was made for a lawful purpose. Recordings that meet these conditions are treated as lawfully obtained evidence.
