Contributions by SSFs to political committees other than candidate committees are generally subject to calendar-year limits.
Contributions to national party committees
An SSF that qualifies as a multicandidate committee may give up to $15,000 per year to a national party committee. A non-multicandidate committee may give up to $33,900 per year to a national party committee during the 2017-18 election cycle. Some political parties have more than one national party committee: The $15,000 or $33,900 limit applies separately to each national committee, House campaign committee and Senate campaign committee
Additionally, national party committees may establish accounts to defray certain expenses incurred with respect to presidential nominating conventions, election recounts and other legal proceedings, and headquarters buildings. The contribution limits applicable to these accounts are 300% of the limits on contributions to national party committees. This means that the accounts may accept up to $45,000 per year from multicandidate SSFs and $101,700 per year from non-multicandidate SSFs during the 2017-2018 election cycle.
Contributions to delegates and delegate committees
An SSF may make unlimited contributions to a delegate (or an individual seeking to become a delegate) attending a national party convention or to a state, district or local convention held to select delegates to a national convention. Contributions by the SSF to a delegate committee (a committee formed by a group of delegates or a group of people seeking to become delegates) are limited to $5,000 per calendar year.
Contributions to other political committees
A multicandidate SSF may make contributions of up to $5,000 per year to any political committee other than a national party committee. A non-multicandidate committee may make contributions of up to $5,000 per year to another committee and $10,000 to a state party committee and its registered local affiliates.
Application of candidate limits to contribution made to unauthorized committee
If an SSF makes a contribution to a committee not authorized by any candidate, and knows that a substantial portion of the contribution will be contributed to, or spent on behalf, of a particular candidate, the contribution counts against the SSF’s per-election limit with respect to that candidate.
Contributions to Super PACs and Hybrid PACs
Pursuant to SpeechNow.org v. FEC and Carey v. FEC, corporations and labor organizations (and their SSFs) may make contributions to nonconnected political committees that make only independent expenditures (a.k.a. Super PACs), or to separate accounts maintained by nonconnected political committees for making only independent expenditures (a.k.a. Hybrid PACs).
