Wolters Kluwer N.V. is a Dutch multinational company that provides professional information, software and services for healthcare, tax, accounting, legal, regulatory, corporate compliance and corporate performance markets. The company is headquartered in Alphen aan den Rijn, Netherlands, and is listed on Euronext Amsterdam.¹

In 2025, Wolters Kluwer reported annual revenue of €6.1 billion and employed approximately 21,100 people. The company stated that it served customers in more than 180 countries and operated in more than 40 countries.¹

The company traces its origins to several Dutch publishing houses, including the schoolbook publisher founded by Jan-Berend Wolters in Groningen in 1836 and Noordhoff, founded in 1858. Wolters and Noordhoff merged in 1968 to form Wolters-Noordhoff. In 1972, Wolters-Noordhoff merged with the Information and Communications Union, which later became Wolters-Samsom.²

Wolters Kluwer was formed in 1987 when Kluwer Publishers merged with Wolters-Samsom. The merger followed an attempted takeover of Kluwer by Elsevier and created one of the largest publishing groups in the Netherlands.²

During the late 1980s and 1990s, Wolters Kluwer expanded internationally through acquisitions in legal, tax, medical and professional publishing. It acquired J. B. Lippincott & Co. in 1990 and CCH Inc., a U.S. tax and business information provider, in 1995 for $1.9 billion.³ In 1998, it acquired Waverly, Ovid Technologies and Plenum Publishing to expand its scientific, technical and medical publishing business.²

In the 2000s, the company increasingly shifted from print publishing toward digital information services and software. In 2007, Wolters Kluwer agreed to sell its education division to Bridgepoint Capital for approximately €774 million.⁴ In 2008, its health division acquired UpToDate, an electronic clinical decision support service.⁵

In 2016, Wolters Kluwer acquired Enablon, a provider of environmental, health, safety and sustainability software, for €250 million.⁶

Wolters Kluwer organizes its business into five divisions: Health; Tax & Accounting; Financial & Corporate Compliance; Legal & Regulatory; and Corporate Performance & ESG.¹

The Health division includes clinical decision support, drug information, medical research and publishing products, including UpToDate, Ovid, Medi-Span, UpToDate Lexidrug and Lippincott medical publishing brands.¹ In 2024, the company said it would group several clinical products under the UpToDate brand, including Lexicomp, renamed UpToDate Lexidrug, and Emmi, renamed UpToDate Patient Engagement.⁷

In the 2026 Best in KLAS report, KLAS Research ranked Wolters Kluwer's Sentri7 products first in the infection control and monitoring and pharmacy surveillance categories, and ranked UpToDate products first in patient education and patient-driven care management.⁸

The Tax & Accounting division provides software and research products for accounting firms, corporations and tax professionals. Its brands include CCH, CCH Axcess and CCH AnswerConnect.¹ Accounting Today included CCH Axcess Tax Essentials and CCH AnswerConnect AI in its 2025 list of top new products for accountants.⁹

The Financial & Corporate Compliance division provides compliance, lending, lien and legal entity management services. Its brands include CT Corporation, ComplianceOne and Lien Solutions.¹ In the 2026 RiskTech100 report, Chartis Research ranked Wolters Kluwer among the top risk technology providers.¹⁰

The Legal & Regulatory division provides legal information and workflow software for law firms, corporate legal departments and government users. Its products include VitalLaw, Legisway and TyMetrix.¹

The Corporate Performance & ESG division provides software for corporate performance management, audit, risk and sustainability reporting. Its brands include CCH Tagetik, TeamMate and Enablon.¹ Verdantix named Wolters Kluwer among the leaders in its 2025 Green Quadrant report on ESG and sustainability reporting software.¹¹

Wolters Kluwer has incorporated artificial intelligence features into several of its software products. In its 2025 annual reporting, the company said that recurring revenues accounted for 83% of total revenue and that approximately 70% of digital revenues came from products it described as AI-powered solutions.¹ In January 2026, Vanderbilt University Medical Center reported that UpToDate Expert AI, a generative artificial intelligence feature for clinical queries, was being made available to its users.¹²

Wolters Kluwer has been included in several corporate sustainability and ESG rankings. In 2015, Euronext stated that the company had received RobecoSAM's Bronze Class Sustainability Award for the eighth consecutive year as part of The Sustainability Yearbook, and that Corporate Knights had included Wolters Kluwer in its Global 100 Most Sustainable Corporations list for the third consecutive year.¹³ Wolters Kluwer also stated that it was included in the Dow Jones Sustainability Indices in 2015 for the ninth consecutive year.¹⁴

In September 2024, UCLA neuroscience professor Lucina Uddin filed a proposed class-action antitrust lawsuit in the United States District Court for the Eastern District of New York against Wolters Kluwer and five other academic publishers: Elsevier, John Wiley & Sons, Sage Publications, Springer Nature, and Taylor & Francis. The complaint alleged that the publishers violated antitrust law by barring simultaneous submissions to multiple journals and by not paying scholars for peer review work.¹⁵¹⁶

On 30 January 2026, U.S. District Judge Hector Gonzalez dismissed the lawsuit, finding that the plaintiffs had not sufficiently alleged a conspiracy among the publishers. The publishers denied wrongdoing.¹⁷¹⁸
