Wisconsin Data Privacy Laws: Breach Notification & Consumer Rights (2026)

Updates

Corrected the security freeze section to include the identity theft fee waiver in Wis. Stat. 100.54(9)(b), replaced a computer crimes bullet describing an offense that does not appear in Wis. Stat. 943.70, removed the incorrect statement that the attorney general and DATCP hold enforcement authority under the breach notification law, added the Wis. Stat. 134.98(2)(cm) conditions under which no breach notice is owed, and corrected two elements of the Wis. Stat. 995.50 right to privacy claim.

Updated the AB 172 / SB 166 comprehensive privacy legislation section to reflect that both bills failed to pass on March 23, 2026, corrected a misattributed police-report security-freeze fee waiver (it applies under Wis. Stat. 100.545 for minors, not the general freeze statute 100.54), and fixed three dead or mistargeted citation links.

Independently fact-checked against the cited primary sources; governing law re-checked for recent changes

Corrected the Wisconsin security-freeze placement deadline from 30 days to the statutory 5 business days (Wis. Stat. 100.54(2)(b)), and added the 10-business-day confirmation-notice deadline the statute also sets.

Governing law re-checked for recent changes

Corrected three mislabeled Wis. Stat. 134.98 subsection citations (civil-claims effect is (4) not (3); the 1,000+ CRA notification rule is (2)(br) not (4); the 45-day deadline is (3)(a) not (3m)), fixed the statute's fourth invasion-of-privacy category under Wis. Stat. 995.50 (conduct prohibited under ss. 942.09/942.095, not a false-light tort), and corrected the Wis. Stat. 943.70 penalty table to show the felony identity-disguise fine enhancement cap of $2,500 (the $1,000 cap applies only to misdemeanors).

Governing law re-checked for recent changes

May 2026 refresh: Added Wis. Stat. 968.31 (one-party consent wiretap) and Wis. Stat. 943.70 (computer crimes) sections -- both previously missing. Added TAKE IT DOWN Act (Pub. L. 119-12) coverage; platform takedown obligations took effect May 19, 2026. Updated AB 172/SB 166 status: AB 172 passed committee 10-0 in January 2026, referred to Rules; both bills subsequently failed to pass pursuant to Senate Joint Resolution 1 on March 23, 2026. Corrected security freeze fee section to reflect federal preemption (free at major bureaus since September 21, 2018). Added DATCP 2024 enforcement stats (11,374 complaints, $23M returned). Added APRA expiration note (died January 2025, not reintroduced). Updated all date references from March 2026 to May 2026. Word count: approximately 4,200 words.
