Venture Capital Fund Structure: Offshore LP vs Onshore Fund

Venture capital fund structuring is driven by a single overriding principle: accommodate the tax and regulatory requirements of the investor base while preserving the economics of the GP/LP relationship. The choice between an offshore limited partnership, a domestic fund, or a parallel structure depends on whether the fund is raising from US taxable investors, US tax-exempt investors, non-US investors, or a combination. Cayman Islands and Delaware dominate VC fund formation, each serving distinct investor segments.

Standard VC Fund Structure

Delaware Limited Partnership (Domestic Fund)

The default structure for VC funds raising primarily from US taxable investors:

• Entity: Delaware limited partnership formed under the Delaware Revised Uniform Limited Partnership Act (DRULPA)
• General Partner: A Delaware LLC owned by the fund principals
• Management Company: A separate LLC that employs the investment team and provides services to the fund
• Tax treatment: Pass-through entity — each LP receives a Schedule K-1 reporting their allocable share of income, gains, losses, and deductions

Cayman Islands Exempted Limited Partnership (Offshore Fund)

Used when the investor base includes non-US investors and US tax-exempt investors:

• Entity: Cayman exempted limited partnership under the Exempted Limited Partnership Act (as revised)
• Purpose: Blocks UBTI for US tax-exempt investors and eliminates US tax filing obligations for non-US investors
• Tax treatment: Cayman has no income tax; non-US LPs are not subject to US tax on the partnership's income (provided the fund is not engaged in a US trade or business)

Parallel Fund Structure

Most institutional VC funds operate parallel vehicles:

• Onshore LP (Delaware): For US taxable investors
• Offshore LP (Cayman): For non-US investors and US tax-exempt investors
• Co-investment vehicles: For LPs investing additional capital alongside the main fund in specific deals

The parallel funds invest side-by-side in the same portfolio companies, pro rata based on committed capital, ensuring all investors receive identical economic exposure.

UBTI Blocking

US tax-exempt investors (pension funds, endowments, foundations, charitable trusts) are generally exempt from federal income tax. However, they are taxed on Unrelated Business Taxable Income (UBTI) under IRC Sections 511-514. UBTI arises from:

• Debt-financed income: If the fund uses leverage (subscription credit lines, bridge financing), the income attributable to borrowed funds is UBTI
• Operating business income: Income from portfolio companies structured as pass-through entities (LLCs, partnerships) may flow through as UBTI

The offshore solution: US tax-exempt investors invest through the Cayman offshore LP, which interposes a Cayman entity (typically a corporation or blocker) between the investor and the income source. Since a Cayman corporation is not a pass-through entity for US tax purposes, the UBTI is blocked at the corporate level.

Carried Interest Mechanics

Carried interest is the GP's share of fund profits — typically 20% of net gains after returning invested capital and a preferred return to LPs.

Waterfall Structures

American waterfall (deal-by-deal):

1. Return of invested capital on each realised deal
2. Preferred return (typically 8% IRR) to LPs
3. GP catch-up (the GP receives distributions until it has received its 20% share of total profits)
4. 80/20 split of remaining profits

European waterfall (whole-fund):

1. Return of all invested capital across the entire fund
2. Preferred return on all invested capital
3. GP catch-up
4. 80/20 split

European waterfalls are more LP-friendly because the GP does not receive carry until all capital across all deals is returned. Most institutional LPs prefer European waterfalls, though American waterfalls with clawback provisions are common in US VC.

Tax Treatment of Carried Interest

Under IRC Section 1061 (enacted by the Tax Cuts and Jobs Act 2017), carried interest is treated as long-term capital gains only if the underlying assets are held for more than three years. Gains on assets held less than three years are recharacterised as short-term capital gains (taxed at ordinary income rates up to 37%).

For VC funds, which typically hold investments for 5 to 10 years, this provision generally does not impact carry economics. However, secondary sales or early exits within three years will be subject to ordinary income treatment.

Fund Economics

Management Fee

• Commitment period (typically years 1-5): 2.0% to 2.5% of committed capital
• Post-commitment period (years 6-10+): Reduced to 2.0% of invested capital (unreturned cost basis)
• Offset: Many LPA provisions require that portfolio company fees (board fees, monitoring fees, transaction fees) earned by the GP offset the management fee by 80% to 100%

Fund Size and Minimum Commitment

• Emerging manager funds: USD 20 million to USD 100 million
• Mid-market funds: USD 100 million to USD 500 million
• Large funds: USD 500 million to USD 5 billion+
• Minimum LP commitment: Typically USD 1 million to USD 5 million for institutional funds; USD 100,000 to USD 500,000 for emerging manager funds

GP Commitment

Institutional LPs expect the GP to commit 1% to 5% of total fund size from personal capital. This aligns the GP's interests with LPs and is a baseline due diligence requirement.

Key Legal Documents

Limited Partnership Agreement (LPA)

The core governing document, covering:

• Capital commitment and drawdown mechanics
• Distribution waterfall
• Management fee calculation
• Carried interest allocation
• Key person provisions (fund pauses or allows redemption if designated principals depart)
• Investment restrictions (concentration limits, geographic restrictions, sector focus)
• GP removal provisions
• LP Advisory Committee (LPAC) composition and authority
• No-fault divorce clause (allows a supermajority of LPs to remove the GP)

Private Placement Memorandum (PPM)

Disclosure document providing investors with:

• Investment strategy and objectives
• Risk factors
• Fee structure
• Biographical information on the investment team
• Track record disclosure
• Regulatory and tax considerations

Subscription Agreement

The investor's commitment document, incorporating representations regarding accredited investor or qualified purchaser status, AML/KYC verification, and ERISA (Employee Retirement Income Security Act) representations.

Regulatory Considerations

SEC Registration

VC fund managers may qualify for the Venture Capital Fund Adviser exemption (Section 203(l) of the Investment Advisers Act), which exempts managers that solely advise venture capital funds from SEC registration. A "venture capital fund" must:

• Represent to investors that it pursues a venture capital strategy
• Invest at least 80% of committed capital in qualifying investments (primarily equity in qualifying portfolio companies)
• Not borrow in excess of 15% of committed capital for more than 120 days
• Not provide redemption rights to investors

Exempt managers must still file Form ADV as "exempt reporting advisers."

AIFMD (EU Investors)

If the fund markets to EU investors, the manager must comply with AIFMD marketing rules. National Private Placement Regimes (NPPRs) allow non-EU managers to market to professional investors in certain EU member states, subject to local notification requirements.

Key Takeaways

• Delaware LP is the standard for US taxable investors; Cayman LP serves non-US and US tax-exempt investors through UBTI blocking
• Parallel fund structures are the institutional norm, allowing all investor types to access the same portfolio on identical economic terms
• Carried interest is taxed as long-term capital gains only if underlying assets are held more than three years (IRC Section 1061)
• European waterfalls are increasingly preferred by institutional LPs, requiring return of all capital before GP carry
• GP commitment of 1% to 5% of fund size is a baseline institutional expectation
• The SEC Venture Capital Fund Adviser exemption provides regulatory relief for qualifying managers, avoiding full SEC registration
