Congressional Budget Office Cost Estimate: H.R. 6729: Empowering Financial Institutions to Fight Human Trafficking Act of 2018 [open pdf - 85KB]
"H.R. 6729 would permit nonprofit organizations to register with the Department of the Treasury to make it easier for those organizations to share information with financial institutions regarding possible human trafficking or money laundering activities. CBO [Congressional Budget Office] estimates that implementing H.R. 6729 would have no significant effect on the federal budget because it would not significantly expand the duties of the department. Enacting the legislation would not affect direct spending or revenues; therefore, pay-as-you-go procedures do not apply. CBO estimates that enacting H.R. 6729 would not increase net direct spending or on-budget deficits in any of the four consecutive 10-year periods beginning in 2029."
