Wisconsin Privacy Law Overview
Wisconsin has not enacted a comprehensive consumer privacy law. Privacy protections for Wisconsin residents come primarily from the state's data-breach notification statute, its consumer-protection law, and the federal privacy framework. Businesses operating in Wisconsin should focus on breach preparedness and on the federal sector rules — health, financial, education — that apply to them, while watching the comprehensive-privacy legislation spreading to neighboring states.
Sector-Specific Privacy Laws in Wisconsin
Wisconsin Consumer Protection Act
Wisconsin's consumer-protection statute prohibits unfair and deceptive trade practices, which the Attorney General can use against businesses that misrepresent how they collect, use, or secure personal information.
Data Breach Notification in Wisconsin
Wisconsin's data-breach notification law requires businesses to notify affected residents when unencrypted personal information is acquired by an unauthorized person.
- Deadline to notify residents: Within 45 days after learning of the breach
- Attorney General notice: No general private-entity Attorney General notification requirement
- Covered data: Name combined with sensitive identifiers (SSN, driver's license, financial-account or medical information, and more)
Pending Privacy Legislation
Comprehensive privacy bills have been introduced in Wisconsin but none has been enacted as of June 2026.
Federal Privacy Laws That Apply in Wisconsin
Even where Wisconsin law is silent, residents and businesses are covered by federal privacy statutes:
- HIPAA — health information held by providers, plans and their vendors
- GLBA — privacy and safeguards rules for financial institutions
- FERPA — student education records
- FCRA — consumer reporting agencies and background screening
- COPPA — online collection of data from children under 13
- FTC Act §5 — unfair or deceptive privacy and data-security practices
Industry-Specific Privacy Requirements in Wisconsin
Many Wisconsin businesses face privacy obligations that flow from their industry rather than from a single state statute:
Healthcare
Providers, health plans and their vendors must comply with HIPAA and with any state medical-confidentiality rules when handling patient information in Wisconsin.
Financial Services
Banks, credit unions, lenders and insurers are subject to the Gramm-Leach-Bliley Act privacy and safeguards rules in addition to Wisconsin consumer-protection requirements.
Technology & Online Services
Companies serving users in other states may owe duties under California's CCPA/CPRA and other comprehensive laws even while Wisconsin itself has none — making multi-state compliance the practical reality for most online businesses.
Retail
Retailers handling payment-card data must meet PCI DSS contractual standards and Wisconsin's breach-notification law if customer information is exposed.
Where to File a Privacy Complaint in Wisconsin
Wisconsin residents who believe a business has mishandled their personal information can file a complaint with the Wisconsin Attorney General, which enforces the state's consumer-protection and data-breach laws. Complaints involving federally regulated data — health, financial, credit or children's information — can also be directed to the Federal Trade Commission or the relevant federal regulator. An attorney can help you assess whether you have a claim and choose the best venue to pursue it.
