Title 26 › Subtitle A — Income Taxes › CHAPTER 1 — NORMAL TAXES AND SURTAXES › Subchapter F — Exempt Organizations › PART I — GENERAL RULE › § 504
If a group was tax-exempt under 501(a) as a 501(c)(3) but then stops being a 501(c)(3) because it did lots of lobbying or took part in political campaigns, it cannot later be treated as a 501(c)(4). The IRS must make rules to stop groups from getting around this rule, including rules about moving assets to other groups controlled by the same people. The rule does not apply if the group was a "disqualified organization" under 501(h)(5) for the tax year right before the first year it stopped being a 501(c)(3).
