# Fiscal Sponsorship **Fiscal sponsorship** is a legal and operational arrangement in which an established **501(c)(3) charitable** or **501(c)(4) social-welfare** organization (the *sponsor*) provides its corporate shell, tax-exempt status, accounting infrastructure, and back-office services to a project that does not have its own separate legal entity (the *sponsored project*). The sponsored project operates with its own name, brand, staff, website, and mission — but **legally**, it is a project of the sponsor. Fiscal sponsorship was developed in the 1960s–70s as a legitimate mechanism for arts collectives, community-organizing projects, social-impact campaigns, and short-term advocacy initiatives that needed institutional homes without each having to incorporate separately. The arrangement remains the principal contemporary operational form for small-to-medium nonprofit projects across most domains of American philanthropic activity. Fiscal sponsorship has also become a **structurally significant feature of the post-[[Citizens United v. FEC]] dark-money architecture**. Large 501(c)(4) organizations operating in the contemporary political-spending landscape have substantially scaled the fiscal-sponsorship model, hosting dozens of distinct political and issue campaigns under a single corporate shell. The result is an analytical-attribution problem: campaigns that appear to the public as independent organizations are legally components of larger 501(c)(4) parents, and the funding flows reaching those campaigns are not separately disclosed. ## How It Works Mechanically In a fiscal-sponsorship arrangement: - **The sponsor** is an established 501(c)(3) or 501(c)(4) organization with IRS-recognized tax-exempt status, a governing board, financial-management infrastructure, legal compliance capacity, and (typically) a small percentage administrative fee on funds it processes - **The sponsored project** has its own name, mission, staff, public-facing identity, programmatic activities, and (often) its own informal advisory structure — but no separate legal incorporation - **Donor contributions** are written to the sponsor (designated for the project) and receive the tax treatment associated with the sponsor's status (deductible if 501(c)(3) sponsor; not deductible but anonymous-permitted if 501(c)(4) sponsor) - **Project staff** are employees of the sponsor, paid through the sponsor's payroll system - **Bank accounts, vendor contracts, and operational expenses** are administered through the sponsor's financial infrastructure, frequently with a separate accounting code or sub-account identifying the project's portion - **Tax filings** are at the sponsor level — the sponsor's IRS Form 990 reports the project's revenue and expenses as part of the sponsor's overall operations - **IRS recognition** requires that the project's activities align with the sponsor's stated tax-exempt purpose The arrangement is formalized through a **fiscal-sponsorship agreement** between sponsor and project that specifies the administrative fee (typically 5%–15% of project revenue), the project's operational autonomy, the sponsor's oversight obligations, and termination provisions (allowing the project to "spin off" into its own corporate entity later if it grows sufficiently or wishes to operate independently). ## The Three Standard Models Fiscal-sponsorship arrangements are conventionally classified into three models, originally articulated by nonprofit attorney Gregory Colvin in the 1990s: ### Model A: Comprehensive (Pre-Approved) The most common model. The sponsor takes **full legal and financial responsibility** for the project, treating it as a program of the sponsor itself. Project staff are sponsor employees; project assets are sponsor assets; sponsor's board has ultimate authority. The project operates with substantial autonomy but is legally indistinguishable from any other program of the sponsor. This is the model used by the **Arabella network** for its dozens of fiscally-sponsored projects under [[Sixteen Thirty Fund]] and the affiliated 501(c)(3) entities. ### Model C: Pre-Approved Grant Relationship The sponsor and project are distinct legal entities, but the project is unincorporated or operates as a project of another organization. The sponsor makes grants to the project after receiving donations designated for it. Less common; used principally for short-term campaigns and time-limited initiatives. ### Model B: Independent Contractor The sponsor contracts with the project as an independent vendor providing services. Used principally for fee-for-service relationships rather than donation-driven projects. Relatively uncommon in the political-spending context. The substantial majority of contemporary politically-active fiscal-sponsorship arrangements use **Model A** — the most legally integrated and the most operationally efficient for scaled multi-project operations. ## Legitimate Use Cases Fiscal sponsorship's original use cases — and the substantial majority of contemporary fiscal-sponsorship arrangements — are uncontroversial: - **Arts collectives.** Artists collaborating on a specific project (a documentary film, a community-arts initiative, a multimedia exhibition) frequently use fiscal sponsorship to receive grants and tax-deductible donations without each project requiring full nonprofit incorporation. The model dates principally from the 1960s arts-funding environment. - **Community organizing.** Neighborhood-level organizing campaigns, single-issue advocacy projects, and time-limited civic initiatives use fiscal sponsorship for operational efficiency. - **Social-impact projects.** Early-stage social-impact initiatives that may scale into independent organizations later but initially operate at scales that don't justify full incorporation overhead. - **Short-term campaign vehicles.** Ballot-initiative campaigns, time-limited policy-advocacy efforts, disaster-response operations. These uses are not analytically distinct from the dark-money use cases described below. The same legal mechanism — sponsor provides shell; project operates under sponsor's tax status — serves both. The structural significance is not in the mechanism itself but in **how the mechanism is scaled and what it enables**. ## The Dark-Money Use Case Post-[[Citizens United v. FEC]] (2010), large 501(c)(4) organizations realized that fiscal sponsorship could be **scaled to host dozens of distinct political-spending and issue-advocacy projects under a single corporate shell**. The structural benefits to the operating network: 1. **Operational efficiency.** Dozens of campaigns share back-office, accounting, legal, and HR infrastructure rather than each maintaining its own 2. **Speed.** New campaigns can launch in weeks rather than the 12–18 months required for new IRS Section 501(c)(4) approval 3. **Donor anonymity inheritance.** The sponsor's [[501(c)(4)]] status — which permits substantial political activity without donor disclosure — applies to all sponsored projects under it 4. **Branding flexibility.** Each campaign can have its own public-facing identity (name, website, communications profile) tailored to its specific audience and issue, while the legal entity behind them remains constant 5. **Asset consolidation.** Donor money contributed across multiple campaigns can be fluidly reallocated between projects as strategic priorities shift, without separate-entity legal constraints The **[[Arabella Advisors]] network** is the most prominent contemporary case. Arabella manages [[Sixteen Thirty Fund]] (501(c)(4)) and three affiliated 501(c)(3) entities (New Venture Fund, Hopewell Fund, Windward Fund), which collectively fiscally sponsor dozens of campaigns. Examples of Arabella-sponsored projects (some active, some completed): - **Demand Justice** — anti-conservative-Supreme-Court advocacy; structurally a project of [[Sixteen Thirty Fund]] - **NextGen Climate Action** (multiple iterations) — climate-policy advocacy - **Health Care Voter** — health-care policy advocacy - **The Hub Project** — broad progressive issue advocacy - **Floridians for a Fair Wage** — state ballot-measure operations - **Our American Story** — pro-immigrant-rights advocacy Each of these operates publicly under its own name with apparent organizational independence. Legally, each is a fiscally-sponsored project of an Arabella-managed entity. The pattern is **bipartisan** in its structural form, though more journalistic attention has focused on the Democratic-aligned Arabella network. Conservative-side parallel uses include: - **Heritage Action** — the 501(c)(4) advocacy arm of the [[Heritage Foundation]] — fiscally sponsors various subsidiary campaign projects - **Various Koch-network operations** — [[Americans for Prosperity]] and adjacent entities use fiscal sponsorship for short-term and project-specific campaigns - **State Policy Network affiliates** — many state-level conservative think tanks operate as fiscally-sponsored projects under regional or national sponsor organizations - **Multiple election-cycle-specific Super-PAC-adjacent operations** — short-term campaign vehicles structured as fiscally-sponsored projects to avoid the formality of separate incorporation ## The Analytical Attribution Problem The structural problem fiscal sponsorship creates for analysis of contemporary political spending is **attribution**. When journalism reports that "Demand Justice spent $20 million opposing [[Brett Kavanaugh]]'s confirmation," the reader naturally infers that "Demand Justice" is a discrete organization with its own funding sources, governance, and accountability structure. The reality: - "Demand Justice" is a fiscally-sponsored project of [[Sixteen Thirty Fund]] - The $20 million is legally **Sixteen Thirty Fund's spending**, with Demand Justice as one of several project categories - The funding sources of "Demand Justice" specifically are not separately disclosed — they are part of Sixteen Thirty Fund's aggregate revenue - Donors who contributed to Sixteen Thirty Fund for unrelated purposes may have funded Demand Justice through fungible-money allocation The same analytical problem applies across virtually all fiscally-sponsored political projects. The visible public attribution (project name) does not match the legal funding attribution (sponsor entity). For sophisticated analysts — including financial-disclosure journalism, opposition political research, and academic campaign-finance research — tracking the actual funding requires understanding the fiscal-sponsorship structure and looking at sponsor-level Form 990 filings rather than at project-level identification. For the public, the analytical problem is substantially intractable. Most readers of political journalism do not understand that "Demand Justice" is not its own organization, and journalism does not typically clarify this point. The structural effect is that **public attribution of political spending is systematically misaligned with legal attribution**. ## IRS and Disclosure Implications For the sponsor's IRS Form 990 filing: - **Project revenue is reported** as sponsor revenue (aggregated, not project-attributed) - **Project expenses are reported** as sponsor expenses (aggregated, not project-attributed) - **Project staff salaries and contractor payments** are reported only if they meet the sponsor-level individual reporting thresholds (top employees, highest-paid contractors) - **Project-specific donors are not reported** — donors give to the sponsor, designated for projects, but the donor's name appears in IRS Schedule B (which is filed but not publicly disclosed for 501(c)(4)s) only at the sponsor level The combined effect: a project may spend tens of millions of dollars on a high-profile political campaign, but the public IRS-disclosure record will show only that the sponsor (e.g., Sixteen Thirty Fund) reported aggregate revenue and expenses. The project-specific funding sources, expenditures, and operational structure are not separately visible in any publicly-available filing. The [[Americans for Prosperity Foundation v. Bonta]] (2021) decision — which substantially constrained state-level requirements for charities to disclose donor names — further restricts the disclosure channels that might have provided project-level transparency. The fiscal-sponsorship model and the *Bonta* decision are mutually reinforcing structural features of the contemporary dark-money architecture. ## Significance for the KB Fiscal sponsorship matters for the KB on four registers: 1. **The structural concept underlying the [[Arabella Advisors]] network.** Understanding why the Arabella network can host dozens of public-facing political campaigns under a small number of corporate shells requires understanding fiscal sponsorship as the legal mechanism. The mechanism is the answer to "how does one 501(c)(4) operate dozens of distinct campaigns?" 2. **The bipartisan structural fact.** Both conservative and progressive infrastructure use fiscal sponsorship. The contemporary political-spending landscape is structured such that **both sides have access to the same scaling mechanism** for project-level operations under a single legal-entity shell. The structural fact is non-partisan even if specific applications are partisan. 3. **The analytical attribution problem.** The contemporary mismatch between public attribution of political campaigns (project names) and legal attribution (sponsor entities) is one of the principal structural features of the post-Citizens-United landscape. The KB tracks numerous specific cases ([[Sixteen Thirty Fund]] subsidiaries, [[Arabella Advisors]] managed projects, etc.) in which the attribution problem applies. 4. **The pre-existing legitimate use.** Fiscal sponsorship is not an invention of the dark-money architecture — it is a legitimate nonprofit-administrative mechanism with multi-decade history of uncontroversial use. The structural significance is in how the mechanism has been **scaled and applied** to the post-2010 political-spending context, not in the mechanism itself. ## See Also - [[Arabella Advisors]] — the principal consultancy managing scaled fiscal-sponsorship operations on the Democratic side - [[Sixteen Thirty Fund]] — the principal 501(c)(4) sponsor in the Arabella network - [[501(c)(4)]] — the entity type that, combined with fiscal sponsorship, produces the dark-money attribution problem - [[527 Organization]] — adjacent entity type with related historical role - [[Dark Money]] — the broader analytical category - [[Citizens United v.
