The maximum penalty for a serious violation in 2025 is $16,550 per violation. For willful violations, the range is $11,823 to $165,514. The current penalty column shows the latest amount on record in OSHA's database for each citation. When the current penalty differs from the initial penalty, OSHA's records show that the amount changed during the enforcement process, but this page does not determine the specific reason for each change. Penalty amounts are set by OSHA and adjusted annually for inflation.
Data Source and Methodology
Data synced dailyData on this page comes from the U.S. Department of Labor's OSHA enforcement database, accessed via the DOL public data API. Records are updated daily. We strive for accuracy, but errors in data processing or establishment matching are possible. Penalty amounts reflect the latest penalty amounts on record in the DOL database and may differ from initial assessments or final amounts after informal conference, settlement, or judicial review. Establishment matching is based on employer name and location as reported in inspection records; some establishments may appear under multiple name variations. Chemical exposure sampling data and OSHA Permissible Exposure Limits (PELs) are sourced from the OSHA Occupational Chemical Database, matched via IMIS analyte codes. If you believe any record is inaccurate, please report it and we will investigate. This product uses the DOL Data API but is not endorsed or certified by the DOL.
