How Turkey’s New Data Protection Law Affects International Companies in 2026

Introduction

Turkey’s new data protection law, effective from 2026, introduces significant changes that international companies operating in or targeting the Turkish market must navigate. This article explores how Turkey’s new data protection law affects international companies in 2026, detailing key requirements, penalties, and strategic steps for compliance.

Background of Turkey’s Data Protection Law

Turkey’s Personal Data Protection Law (Law No. 6698) was originally enacted in 2016, modeled after the EU’s GDPR. However, the 2026 amendments strengthen provisions, especially regarding cross-border data transfers, consent requirements, and enforcement. The law applies to any company that processes personal data of individuals in Turkey, regardless of where the company is based.

Key Changes in the 2026 Amendments

Stricter Cross-Border Data Transfer Rules

International companies must now obtain explicit consent from data subjects for transfers abroad, or rely on specific adequacy decisions, standard contractual clauses (SCCs), or binding corporate rules (BCRs). The Turkish Data Protection Authority (KVKK) has also introduced a mandatory registration requirement for data transfers to countries without adequacy status.

Enhanced Consent Requirements

Consent must be freely given, specific, informed, and unambiguous. The new law prohibits pre-ticked boxes and requires separate consent for each processing purpose. Silence or inactivity no longer constitutes consent.

Increased Penalties and Fines

Administrative fines have been substantially increased. For serious violations, fines can reach up to 5% of annual global turnover or 10 million Turkish Lira (whichever is higher). Additionally, company executives may face personal liability.

Mandatory Data Protection Officer (DPO) Appointment

International companies that process large-scale data or sensitive data must appoint a DPO based in Turkey. The DPO must be registered with the KVKK.

Impact on International Companies

Data Localization Requirements

While not strictly requiring data localization, the new law imposes conditions that make it challenging to transfer data out of Turkey. Many international companies may need to store and process data within Turkey to avoid complexity.

Compliance Costs and Operational Changes

Companies must update privacy policies, consent mechanisms, data processing records, and data transfer agreements. This requires investment in legal counsel, technology, and personnel training.

Risk of Enforcement Actions

The KVKK has ramped up enforcement. In 2025, it imposed fines on several multinationals for non-compliance. International companies should expect increased scrutiny.

Steps for International Companies to Comply

• Conduct a Data Audit: Identify what personal data of Turkish residents you process, where it is stored, and how it is transferred.
• Update Legal Documentation: Revise privacy notices, consent forms, and data processing agreements to align with new requirements.
• Implement Consent Management: Use robust consent management platforms that capture granular, documented consent.
• Review Data Transfer Mechanisms: Assess adequacy decisions, SCCs, or BCRs for cross-border transfers. Consider local hosting if necessary.
• Appoint a DPO: If required, designate a DPO based in Turkey and register with the KVKK.
• Train Employees: Ensure staff handling personal data understand the new obligations.
• Monitor Regulatory Updates: The KVKK continues to issue guidelines. Stay informed.

Case Studies: How Companies Are Adapting

E-commerce Platform

A global e-commerce company revised its consent flow to obtain separate approvals for marketing, analytics, and data sharing. It also moved Turkish user data to servers in Turkey to simplify compliance.

Software as a Service (SaaS) Provider

A US-based SaaS provider updated its standard contractual clauses and implemented data encryption for all data in transit to Turkey. It also appointed a local data protection officer.

Conclusion

Turkey’s new data protection law in 2026 significantly affects international companies by imposing stricter rules on cross-border data transfers, consent, and accountability. To avoid substantial fines and reputational damage, companies must proactively adapt their data processing practices.
