South Korea's 2025 AI Compliance Overhaul: What Professional Services Firms Must Know

South Korea has moved decisively to bring artificial intelligence under a formal regulatory framework. With landmark legislation now on the statute books and enforcement penalties rising sharply, international professional services firms and global enterprises operating in or serving Korean markets face a materially changed compliance environment. This briefing sets out what has changed, what is coming, and what your organisation needs to do.

The AI Basic Act: A Single Framework Replaces Fragmented Rules

After years of competing legislative proposals, South Korea's Basic Act on the Development of Artificial Intelligence and Establishment of Trust — commonly referred to as the AI Basic Act — was passed by the National Assembly in December 2024 and formally promulgated in January 2025. Full enforcement begins in January 2026.

The Act consolidates South Korea's previously fragmented approach to AI governance into one coherent framework. Its structure will be familiar to organisations already working with the EU AI Act: it is risk-based, distinguishing between AI systems according to the potential severity of their impact. "High-impact" AI systems and generative AI applications attract the most demanding obligations, including mandatory risk assessments, the implementation of defined safety measures, and documented transparency obligations toward users.

What demands immediate attention for international businesses is the Act's extraterritorial scope. Like GDPR before it, the AI Basic Act applies to AI systems that affect Korean markets or users, regardless of where those systems are developed or where the deploying organisation is headquartered. A professional services firm headquartered in London, Frankfurt, or Singapore that uses AI tools touching Korean clients or data subjects falls within scope. The Ministry of Science and ICT (MSIT) is responsible for issuing subordinate regulations — expected in the first half of 2025 — that will provide the granular implementation detail businesses need to build compliance programmes.

Critically, foreign entities subject to the Act must designate a local representative in South Korea. This mirrors the representative requirement already familiar from GDPR Article 27 and signals a broader international trend toward localised accountability for foreign operators.

PIPA Amendments: Stronger Data Rights, Higher Stakes

Parallel to the AI Basic Act, South Korea's Personal Information Protection Act (PIPA) has been substantially strengthened through a series of amendments that are now taking effect in stages.

From March 2025, individuals gained data portability rights, enabling them to request the transfer of their personal information held by organisations. The September 2024 amendment to PIPA's Enforcement Decree also tightened consent requirements, emphasising that consent must be genuinely voluntary and clarifying that data strictly necessary for contract performance may be collected without explicit consent — a useful but carefully bounded carve-out.

Foreign businesses operating in South Korea must now also appoint a domestic privacy representative, with that requirement taking effect from 2 October 2025. This obligation sits alongside the AI Basic Act's local representative requirement, meaning some international organisations may need to satisfy both in parallel, potentially through the same appointed entity.

The Personal Information Protection Commission (PIPC) — South Korea's data protection supervisory authority — has been equally active on the guidance front. In May 2024, it clarified how public personal information may be used for AI training under a legitimate interests basis, subject to specific conditions. In August 2025, the PIPC published a comprehensive Personal Information Processing Guide for the Development and Use of Generative AI, which maps minimum safety standards across a four-stage AI lifecycle framework. Organisations developing or deploying generative AI that processes personal data of Korean residents should treat this guide as essential reading.

The PIPC has also issued detailed regulations on automated decision-making, effective from March 2024, giving individuals the right to request explanations of — and challenge — automated decisions that significantly affect them. For professional services firms using AI in credit analysis, legal document review, HR screening, or client risk profiling, these rights create direct operational obligations.

Enforcement Is No Longer Theoretical

The regulatory environment has teeth. Amendments to PIPA effective from March 2026 raise the maximum administrative penalty for serious violations from 3% to 10% of total revenue — a significant step up applicable in cases of repeated breaches, incidents affecting ten million or more data subjects, or failure to comply with a corrective order.

The direction of travel is already visible. In May 2024, the PIPC imposed a penalty of KRW 7.5 billion (approximately USD 5.2 million) on Golfzon following a data breach — at that time the largest fine levied on a domestic company. That precedent, set before the enhanced penalty regime takes effect, signals that Korean regulators are prepared to act with force. International firms should not assume that being headquartered outside Korea affords any meaningful protection.

What This Means for International Professional Services Firms

The convergence of the AI Basic Act and strengthened PIPA creates a multi-layered compliance burden that requires structured attention across several dimensions.

Jurisdictional reach requires honest scoping. Organisations should map every AI system — whether internally built or procured from a third-party vendor — that touches Korean users, Korean personal data, or Korean market activity. Assuming territorial insulation without conducting this analysis is a compliance risk in itself.

Governance structures need updating. Risk assessments for high-impact and generative AI systems are mandatory under the AI Basic Act. Firms that have not yet embedded AI-specific risk assessment into their procurement and deployment processes should do so now, ahead of the January 2026 enforcement date.

Local representative obligations must be actioned. Both the AI Basic Act and the revised PIPA require foreign organisations to appoint Korean representatives for AI and privacy accountability respectively. Identifying and formalising these appointments — and ensuring those representatives have genuine authority and resources — is an operational task that cannot be deferred.

Third-party and supply chain exposure is real. Professional services firms that rely on AI-enabled tools from global software vendors remain responsible for compliance outcomes. Vendor contracts and due diligence processes should be reviewed in light of the new Korean requirements, including how those vendors handle personal data within AI systems.

Automated decision-making transparency is now a client-facing issue. Where AI is used to generate outputs that materially affect clients or individuals — in legal, financial, consulting, or HR contexts — firms need documented processes for explaining those outputs and handling challenge requests.

Act Now, Before January 2026

South Korea's AI compliance landscape has shifted considerably in the past twelve months, and it will shift further as MSIT subordinate regulations are finalised and the penalty regime intensifies in 2026. Organisations that treat this as a future problem are already behind.

Ops Intel works with international professional services firms and global enterprises to build practical, jurisdiction-specific AI compliance programmes. If your organisation has exposure to Korean AI or data protection obligations — or if you are managing compliance obligations across multiple jurisdictions simultaneously — our team can help you assess your current position and develop a credible path to compliance.
