SB 403 Wisconsin Senate · 2025-2026 Regular Session

Relating to: online credit card contributions and providing a penalty.

SB 403 requires political committees, conduits, and parties to verify the credit card verification value (CVV) and a U.S. billing address for online credit card donations. It directly affects organizations accepting such donations, with an exception for U.S. citizens living abroad who must instead provide their U.S. voter registration address. The bill mandates treasurers to maintain donor records for reporting and imposes penalties on financial institutions that process these donations without the required verification, requiring them to forfeit the full contribution amount. This aims to enhance transparency and prevent fraudulent or non-compliant online political donations.
