Salvatore Groppo’s guilty plea for involvement in an unlawful sports gambling operation did not shield him from substantial IRS tax liabilities. Despite fulfilling his probation terms, Groppo faced over $100,000 in excise tax and penalties, which he unsuccessfully tried to settle. His appeal to expunge his felony conviction, aimed at negating the IRS’s tax assessment, was denied by the 9th Circuit Court. The court emphasized that the plea deal did not bind other authorities, reaffirming that tax liabilities remain despite a plea agreement.
