Search Fund Legal Structure & Entity Setup

One of the earliest decisions a search fund entrepreneur faces is how to structure the legal entities that will house the search, the investor capital, and ultimately the acquired business. Getting this wrong creates tax inefficiencies, complicates fundraising, and can even derail a deal at closing. This guide walks through the dominant structures in the United States and across key European jurisdictions, explains why the two-entity model is standard, and outlines when and how to set everything up.

Why structure matters

The legal structure of your search fund determines four critical things: how investors contribute and recover capital, how profits and losses flow for tax purposes, what liability protections you and your investors enjoy, and how cleanly the acquisition vehicle can purchase a target company. A poorly chosen structure can trigger double taxation, create securities-law complications, or force an expensive reorganization right when you should be focused on closing a deal.

The two-entity model explained

The standard search fund architecture uses two separate legal entities. The first is an investment vehicle (typically a limited partnership or LLC) through which investors commit capital. The second is an operating entity (often a new LLC or corporation) that actually acquires and operates the target business. Keeping these separate achieves several goals:

• Liability isolation: Investor capital in the LP is shielded from operating liabilities of the acquired business, and vice versa.
• Clean deal mechanics: The operating entity is the buyer on the purchase agreement, making it simpler for sellers, lenders, and counterparties.
• Tax efficiency:A pass-through investment vehicle (LP or LLC) avoids entity-level taxation, letting gains and losses flow directly to investors' personal returns.
• Flexibility at exit: Two entities make it easier to structure a future sale, whether as a stock sale of the operating company or an asset sale.

United States: The standard structure

The LP investment vehicle

Most US search funds raise capital through a Limited Partnership (LP)formed in Delaware. The searcher (or a single-member LLC controlled by the searcher) serves as the General Partner (GP), and each investor becomes a Limited Partner. Delaware is preferred for its well-developed body of partnership law, the Court of Chancery's expertise in business disputes, and its flexibility in drafting partnership agreements. The LP agreement governs capital calls, distribution waterfalls, the searcher's carried interest, investor rights of first refusal on the acquisition, and governance provisions such as voting thresholds for major decisions.

The LLC operating entity

When a target is identified, the searcher forms a new Limited Liability Company (LLC)— or sometimes a C-Corporation — to serve as the acquisition vehicle. The LP invests its capital into this operating entity, which then purchases the target's assets or equity. An LLC taxed as a partnership is the most common choice because it provides pass-through taxation and maximum flexibility in allocating income, losses, and distributions among the searcher and investors. If the searcher plans to pursue Qualified Small Business Stock (QSBS) treatment under Section 1202, a C-Corporation may be preferred instead.

The GP entity

The searcher typically creates a small single-member LLC to serve as the General Partner of the LP. This adds another layer of personal liability protection between the searcher and the fund's obligations. The GP entity is usually a simple Delaware or home-state LLC with minimal operating costs.

European structures by country

European search funds face a more fragmented legal landscape. Each country has its own entity types, tax regimes, and corporate governance requirements. Below are the most common structures in the four largest European search fund markets.

France

France has become one of the most active search fund markets in Europe, driven in part by strong alumni networks from INSEAD, HEC Paris, and ESSEC. The typical French structure involves:

• SAS (Societe par Actions Simplifiee): The most popular entity for both the holding company and the operating company. The SAS offers enormous flexibility in governance, share classes, and shareholder agreements. It has no minimum board requirements and allows customized voting and economic rights — ideal for replicating the US search fund economics.
• SARL (Societe a Responsabilite Limitee): A simpler limited-liability entity sometimes used for smaller deals. The SARL is less flexible than the SAS for complex cap tables but has lower administrative overhead.
• Holding de reprise:French searchers commonly set up a dedicated holding company (a “holding de reprise”) to acquire the target. This holding can benefit from the “integration fiscale” regime, which allows the holding and its subsidiary to be taxed as a single fiscal group, enabling interest deductions on acquisition debt to offset operating profits of the target.

Germany

The German search fund market is growing, though it remains smaller than France. German structures tend to involve:

• GmbH (Gesellschaft mit beschrankter Haftung): The standard limited-liability company and the most common choice for the acquisition vehicle. A GmbH requires a minimum share capital of EUR 25,000. It is subject to corporate tax (Korperschaftsteuer) at approximately 15% plus a solidarity surcharge, as well as trade tax (Gewerbesteuer) that varies by municipality but typically adds another 10-17%.
• UG (Unternehmergesellschaft):A “mini-GmbH” with a minimum capital of just EUR 1. Some searchers use a UG as the GP entity or as an initial holding vehicle during the search phase to minimize upfront costs, converting to a GmbH later.
• GmbH & Co. KG: A limited partnership (KG) where the general partner is a GmbH rather than a natural person. This structure combines partnership-level pass-through taxation with GmbH-level liability protection for the GP. It is the closest German equivalent to the US LP + LLC GP model and is increasingly used by German search funds with multiple investors.

United Kingdom

The UK has a relatively straightforward entity landscape:

• Ltd (Private Limited Company): The standard vehicle for both the holding entity and the operating company. Formation is fast and inexpensive (Companies House registration can be completed online in 24 hours). Corporation tax is 25% for profits above GBP 250,000, with a lower 19% rate for small profits below GBP 50,000 and marginal relief in between.
• LLP (Limited Liability Partnership): Sometimes used as the investment vehicle to provide partnership-style pass-through taxation to investors while maintaining limited liability. UK LLPs are transparent for tax purposes — profits are taxed at the partner level, not the entity level.
• EIS and SEIS relief: UK investors may benefit from the Enterprise Investment Scheme (EIS) or Seed Enterprise Investment Scheme (SEIS), which provide income tax relief of 30% or 50% respectively on qualifying investments in small companies. Structuring the deal to qualify for EIS can be a meaningful incentive for UK-based angel investors.

Spain

Spain, driven largely by the IESE Business School alumni network, has a well-established search fund community. The primary vehicle is:

• SL (Sociedad Limitada): The Spanish equivalent of a limited liability company. Minimum share capital is EUR 3,000. The SL is by far the most common entity type for both search fund holding companies and operating entities in Spain. It is subject to corporate tax (Impuesto sobre Sociedades) at a standard rate of 25%, with a reduced rate of 15% for newly created entities in their first two profitable years.
• SA (Sociedad Anonima): The public limited company equivalent, requiring EUR 60,000 in minimum capital. Rarely used for search funds but sometimes relevant when acquiring a larger target that was already structured as an SA.
• Holding structure:Spanish searchers commonly create a holding SL to acquire the target SL. Spain's participation exemption regime allows the holding company to receive dividends and capital gains from subsidiaries in which it holds at least 5% essentially tax-free, making the holding structure efficient for distributing proceeds at exit.

Tax implications of entity choice

The entity you choose has direct consequences for how income is taxed, both during the hold period and at exit. In the US, pass-through entities (LPs and LLCs taxed as partnerships) avoid double taxation: profits flow to investors' personal returns and are taxed once. A C-Corporation, by contrast, pays corporate tax on profits and shareholders pay tax again on dividends or capital gains — though QSBS treatment under Section 1202 can eliminate federal capital gains tax on up to $10 million (or 10x basis) if the stock is held for at least five years.

In Europe, most entities are subject to corporate-level taxation, so the focus shifts to minimizing the effective rate through holding structures, participation exemptions, and treaty-based planning. France's integration fiscale, Germany's Organschaft regime, and Spain's participation exemption are all tools that experienced tax advisors use to optimize the structure.

When to set up your entities

• Before fundraising: The LP (or equivalent investment vehicle) must exist before you accept investor commitments. Securities regulations require investors to subscribe to a specific legal entity with a defined offering document.
• During the search: The GP entity should be formed at the same time as the LP. The operating entity, however, is typically not formed until a target has been identified and you are preparing to close.
• Before closing:The operating / acquisition entity must be formed well before closing — lenders, sellers, and escrow agents need the entity's formation documents, EIN (or local equivalent), and bank accounts in place.

Working with lawyers

Search fund entity setup is not a do-it-yourself project. You need counsel experienced with search fund structures specifically — not just any corporate attorney. The right lawyer will draft your LP agreement (or equivalent), advise on securities compliance for the fundraise, structure the acquisition vehicle for tax efficiency, and coordinate with local counsel if you are operating cross-border.

In the US, a handful of law firms dominate the search fund market and offer standardized documents that investors recognize and trust. In Europe, the landscape is more fragmented, and you may need local counsel in the target's jurisdiction alongside a firm familiar with ETA deal structures. Budget EUR 15,000 to EUR 40,000 for entity setup and LP documentation in Europe, and $15,000 to $30,000 in the US. These fees are typically paid from search capital.

Start conversations with lawyers early — ideally before you begin fundraising — so that your entity structure, offering documents, and investor agreements are ready when you start taking meetings. A well-prepared legal package signals professionalism to investors and avoids delays that can cost you momentum.
