The "No Tax Breaks for Union Busting (NTBUB) Act" aims to amend the Internal Revenue Code of 1986 by ending tax deductions for employer efforts to influence their workers' exercise of rights concerning labor organizations and collective action. Congress finds that despite the National Labor Relations Act's intent to protect workers' rights to organize, many employers spend millions annually on consultants and tactics to sway employee opinions, often involving unfair labor practices, which currently remain tax-deductible. The core provision of the bill modifies Section 162(e)(1) of the Internal Revenue Code to explicitly deny deductions for "any attempt to influence the taxpayer's employees with respect to labor organizations or labor organization activities." This includes activities related to labor organization elections, labor disputes, and collective actions as defined under the National Labor Relations Act and the Railway Labor Act. Specifically, non-deductible expenses will include amounts paid or incurred in connection with actions resulting in an unfair labor practice complaint , a settlement of such a charge, or a finding of interference by a federal court. It also covers costs associated with producing or conducting meetings or trainings where labor organizations or activities are discussed with employees, and any amounts required to be reported under the Labor-Management Reporting and Disclosure Act of 1959. However, the bill provides several exceptions, allowing deductions for expenses related to legitimate labor relations activities. These include amounts paid for communications or negotiations directly with designated employee representatives , legally required communications with shareholders, and expenses for voluntarily recognizing a labor organization. Costs associated with labor-management partnerships, grievance procedures, or communications legally required to be posted for employees also remain deductible. Furthermore, the bill establishes new information reporting requirements for employers and third parties engaging in these activities. Employers must provide detailed information on non-deductible expenditures, facing penalties for non-compliance, including a minimum of $10,000 or $1,000 per full-time equivalent employee. The Secretary of the Treasury is mandated to issue guidance and regulations within 240 days of enactment, with the amendments applying to taxable years beginning after this 240-day period.
