AZ HB2509

Requires corporations, limited liability companies, and labor organizations to register and notify filing officers within one day of making political contributions to candidate-related races: $5,000+ for statewide races, $2,500+ for legislative races, or $1,000+ for local races.

Mandates registration include the entity's name/address and authorizing person's contact information, while notifications must disclose contribution amounts, recipients, candidate names, and whether contributions support or oppose candidates.

Requires a notarized sworn statement within five days confirming the person filing had authority to make contributions on behalf of the entity; unverified filings are labeled as such and removed if unverifiable.

Establishes civil penalties of up to three times the contribution amount for failure to register, notify, or disclose as required, with enforcement by the attorney general or local prosecutors.

Makes knowingly false filings a class 1 misdemeanor, though enforcement actions cannot proceed until the filing officer issues a reasonable cause determination.
