Many contractors end up with multiple entities over time, one for the operating business, one holding real estate, maybe another for equipment. Each decision made sense individually. Together, they can create tax inefficiency nobody designed on purpose.
How This Usually Happens
- An entity is formed to hold a piece of real estate for liability protection
- Another is created to separate a new division or region
- A third holds equipment for leasing flexibility back to the operating company
- A fourth appears almost by accident, formed years ago for a project that never materialized, and simply never dissolved
Each is reasonable in isolation. Collectively, they often result in:
- Duplicated administrative costs, separate accounting, filings, and registered agent fees for each entity
- Missed opportunities to net income and losses across entities where legally permissible
- Retirement plan design that fails to account for controlled group rules
- Confusion at tax time over which entity should bear which deductible expense
The Controlled Group Problem
When multiple entities share common ownership above certain thresholds, the IRS treats them as a controlled group for retirement plan purposes. This can mean:
- Employees across all entities must be considered for plan testing, even employees in an entity the owner rarely thinks about
- Retirement plan contributions intended for one entity's owner may trigger unexpected obligations across others
- Compliance failures can jeopardize the tax-favored status of the entire plan structure, not just the plan tied to the entity where the failure occurred
Many owners discover this only after a plan audit, not before, at which point correcting the structure retroactively is far more expensive than designing it correctly from the start.
A Closer Look: A Structure That Grew Without a Plan
A contractor starts with a single operating LLC. Over the following decade, a second entity is formed to hold the company's real estate, a third to hold equipment that gets leased back to the operating business, and a fourth is created for a joint venture project that ultimately never happens but is never formally dissolved. None of these decisions were unreasonable at the time. But ten years later, when the owner wants to install a more generous retirement plan for themselves, a plan design review reveals that all four entities are treated as a controlled group. Employees across all four must be included in testing, an unused entity is still technically part of the group, and the retirement plan the owner actually wants is far more complicated, and more expensive, to implement than it would have been with a cleaner structure from the beginning.
A Coordinated Approach
1. Map every entity and its ownership structure in one place. Most owners have never seen this laid out visually, ownership percentages, formation dates, and current purpose of each entity, side by side.
2. Review entities against controlled group rules before finalizing any retirement plan design. This review should happen before plan design begins, not after a plan is already in place and being tested for compliance.
3. Evaluate whether consolidation, or a formal management holding structure, would reduce administrative drag and improve tax efficiency. Not every entity needs to be collapsed, but many multi-entity structures accumulate at least one entity that no longer serves a real purpose and is simply costing money to maintain.
4. Formally dissolve entities that no longer serve an active purpose. An unused entity from a project that never materialized still counts toward controlled group determinations and still generates filing obligations, until it is properly closed.
Questions Worth Asking Yourself
- Can you name every entity you currently own, its purpose, and its ownership percentage, without looking it up?
- Has your entity structure ever been reviewed specifically against controlled group rules?
- Do you have an entity that no longer serves an active purpose but has never been dissolved?
- Was your current retirement plan designed with full knowledge of your complete entity structure?
Closing Perspective
Multiple entities often start as smart, protective decisions. Over time, without coordination, they can quietly work against the tax efficiency and retirement planning they were never designed to interfere with.
A periodic entity structure review, done alongside a CPA and financial advisor together, is one of the more overlooked ways contractors leave money on the table, and one of the easier problems to fix once it is actually identified.
