Fund Structure
Last updated
Quick Answer
A corporate entity interposed between a fund and certain investors (tax-exempt or foreign) to block the flow-through of unrelated business taxable income or U.S. tax filing obligations.
A Blocker Corporation is a corporate entity (typically a C-corporation organized in Delaware or an offshore jurisdiction) inserted between a venture fund and certain categories of investors to prevent unfavorable tax consequences from flowing through to those investors. For U.S. tax-exempt investors (endowments, foundations, pension funds, IRAs), a blocker prevents Unrelated Business Taxable Income (UBTI) from flowing through the partnership structure—without the blocker, these investors could face taxes on what should be tax-exempt investment returns. For non-U.S. investors, a blocker prevents the creation of U.S. tax filing obligations and potential withholding on Effectively Connected Income (ECI) under FIRPTA rules. The blocker corporation pays corporate-level tax on its share of fund income, but this is often preferable to the alternative tax consequences for the investors it serves. Blockers add cost and complexity (corporate formation, separate tax filings, potential double taxation) and are typically used only when the tax benefits outweigh these costs.
In Practice
A university endowment (tax-exempt) wants to invest in a venture fund that generates UBTI through debt-financed investments and operating businesses. Without a blocker, the UBTI would flow through the partnership and create taxable income for the normally tax-exempt endowment. The fund creates a blocker C-corp: the endowment invests in the blocker, which in turn invests in the fund. Income is trapped at the blocker level and taxed at corporate rates, but the endowment avoids UBTI entirely, preserving its tax-exempt status.
Why It Matters
Blocker corporations are essential tax planning tools that enable tax-exempt and foreign investors to participate in venture funds without adverse tax consequences. GPs must understand which investors need blockers and structure their funds accordingly. Failure to provide proper blocker structures can exclude major LP categories from investing.
VC Beast Take
Blocker corps are one of those unsexy fund mechanics that separate amateur GPs from pros. Most first-time fund managers discover they need one only after a major pension fund or endowment wants to invest but can't due to UBTI concerns. Smart GPs set up blockers from day one, even if it adds $50K+ in annual costs. The alternative—losing a $25M LP commitment because you didn't plan ahead—makes the expense look trivial.
