Tax Equity Act of 201 7 This bill amends the Internal Revenue Code to provide for regional cost-of-living adjustments in individual income tax rates. The bill also directs the Department of Labor to determine and publish a regional cost-of-living index for each statistical area for 2017 and each calendar year thereafter. A "statistical area" is: (1) any metropolitan statistical area as defined by the Department of Commerce, and (2) the portion of any state not within a metropolitan statistical area.
