Personal Data Breach Penalties Just Jumped to 10% of Revenue -- Here's What Changes on September 11

Starting tomorrow, the penalty ceiling more than triples

Not every breach triggers the maximum fine

The 10% ceiling only applies to three specific situations defined by law. 1) Repeated violations within a 3-year window caused by intent or gross negligence, 2) a breach affecting 10 million or more people caused by intent or gross negligence, and 3) a breach that occurs because a company failed to comply with a corrective order from the Personal Information Protection Commission (PIPC). A small company that has a single, accidental breach isn't automatically looking at 10% of its revenue disappearing.

What actually counts as "gross negligence"

The phrase "gross negligence" appears twice in the criteria that trigger the maximum penalty, and the determination is made case by case through PIPC review. Past enforcement decisions, however, suggest that failing to implement basic safeguards like encryption, leaving a known security vulnerability unpatched, or neglecting access-control management tend to be treated as gross negligence. A breach from a genuinely novel attack method, or one that happens despite reasonably standard security measures being in place, is more likely to be evaluated differently.

Companies that invested get a discount

A company that can show a track record of investing budget, staff, and infrastructure in personal data protection can have its fine reduced by up to 40%, even after the same kind of breach. The flip side is that a company with no dedicated privacy staff and no history of related investment has little basis to argue for a reduction -- and is more likely to land near the maximum penalty if something goes wrong.

What actually changes for you as a user

A bigger fine for the company doesn't create a new direct compensation process for affected users. That said, a portion of the penalty revenue is designed to fund public relief efforts, so a large-scale breach going forward should come with a somewhat deeper government relief fund than before. If you're an individual seeking compensation, you still need to go through the existing process of confirming, blocking, and claiming after a breach notification.

What companies should check right now

Because one of the three trigger conditions is "a breach caused by failing to comply with a corrective order," documenting whether corrective orders were followed on time becomes especially important. Slow follow-through on a PIPC order is itself a path to the highest tier of penalty. Naming a data protection officer and keeping records of access-control management, encryption, and regular security reviews is the first step toward building a case for a reduced penalty if something does go wrong.

If your data has already been breached before

This amendment strengthens penalties for breaches going forward -- it is not retroactive to breaches that already occurred. If you've received a breach notification in recent years, your personal options haven't changed: you can still change a compromised resident registration number, or request access to and deletion of your personal data, regardless of this new penalty structure.

The bottom line

A 10% penalty ceiling doesn't mean regulators can take 10% of any company's revenue for any breach -- it means the upper limit rose for three specific serious scenarios: repeat violations, large-scale harm, and ignoring a corrective order. For companies, the key is documenting a real investment history to build a case for a reduced penalty. For individuals, the existing breach-notification and data-deletion procedures are unchanged by this update. The actual violation finding and any reduction percentage are decided case by case through PIPC review, so anyone facing an actual enforcement action should get professional legal advice.
