Trash Reduction Act of 2013 - Amends the Internal Revenue Code to require retailers to pay a $0.05 excise tax on each disposable carryout bag provided to a consumer. Defines "disposable carryout bag" to mean a bag of any material, commonly plastic or kraft paper, which is provided to a consumer at the point of sale to carry or cover purchases, merchandise, or items. Exempts reusable bags and certain other bags used for specified purposes from such tax. Allows a refund of such tax for retailers who establish a disposable carryout bag recycling program.
Establishes in the Treasury the Disposable carryout bag Trust Fund to hold tax revenues generated by this Act. Directs the Secretary of the Treasury to make payments from such Trust Fund for the disposable carryout bag recycling program and for the land and water conservation fund established by the Land and Water Conservation Fund Act of 1965.
Directs the Comptroller General to report to Congress on the effectiveness of this Act in reducing the use of disposable carryout bags and encouraging recycling of such bags.
