Improper Tax Payments Reduction Act of 2017

This bill amends the Internal Revenue Code, with respect to the earned income tax credit, to: (1) specify that a taxpayer must claim all allowable deductions when determining net earnings from self-employment, (2) require employers who report wages to include the name and address of each employee and the amount of reportable wages received by each of those employees, and (3) limit earned income to amounts substantiated by the taxpayer on statements furnished or returns filed under third-party information reporting requirements or amounts substantiated by the taxpayer's books and records.
