A bill introduced in the U. S. House of Representatives intends to prohibit tax exemptions under Section 501(c)(4) of the Internal Revenue Code for social welfare organizations engaged in political activity.

House Bill 2338, the 501(c)(4) Reform Act of 2017, amends the Internal Revenue Code to prohibit 501(c)(4) entities from participating in, or intervening in (including the publishing or distributing of statements), any political campaign.

Rep. Michelle Lujan Grisham introduced the legislation on May 3. The bill is currently in the House Committee on Ways and Means.
