If the form is filed by mail, no civil late penalty shall be assessed for any day after the date of postmark. No civil late penalty shall be assessed for any day when the Board office at which the report is due is closed. The State Board shall immediately notify, or cause to be notified, late filers, from which reports are apparently due, by mail, of the penalties under this section. The State Board of Elections may waive a late penalty if it determines there is good cause for the waiver.
If the Board determines by clear and convincing evidence that the late filing constitutes a willful attempt to conceal contributions or expenditures, the Board may assess a civil penalty in an amount to be determined by that Board, plus the costs of investigation, assessment, and collection. The civil penalty shall not exceed three times the amount of the contributions and expenditures willfully attempted to be concealed.
