When U.S. corporations and wealthy individuals use offshore tax havens to avoid paying taxes to the federal government, it is an abuse of our tax system. Tax haven abusers benefit from our markets, infrastructure, educated workforce, and security, but they pay next to nothing for these benefits. Ultimately, taxpayers must pick up the tab, either in the form of higher taxes, cuts to public spending priorities, or increased national debt.
Tax havens are countries or jurisdictions with minimal or no taxes. Corporations and individuals shift earnings to financial institutions in these countries to reduce their U.S. income tax liability—costing the federal government $150 billion in lost revenues each year.
Federal taxpayers are not the only victims of offshore tax havens. Tax havens deprive state governments of billions of dollars in badly needed revenues as well. Based how much income is federally reported in each state, and on state tax rates, it is possible to calculate how much each of the state governments lose as a result of offshore tax dodging. In 2012, the state of Illinois lost $2.5 billion.
