Most tax advice stops at the S-Corp election. And for good reason—it’s the right move for businesses in the $80K-$250K profit range. But as income grows, the optimization surface expands dramatically.
This isn’t about aggressive tax schemes. It’s about understanding how sophisticated business owners legally structure their affairs—and why single-entity thinking leaves money on the table.
When Single-Entity Structures Break Down
The S-Corp sweet spot has limits. At higher income levels, several factors emerge:
Reasonable salary pressure increases. With $500K in profit, the IRS expects more than $100K in salary. Your distribution advantage shrinks proportionally.
QBI deduction phases out. The 20% Qualified Business Income deduction phases out between $383,900-$483,900 (married filing jointly, 2026). High earners lose this entirely for specified service businesses.
State tax efficiency varies. Some structures work in Nevada that don’t work in California. Multi-state operations compound complexity.
Asset protection becomes critical. One successful lawsuit against a single-entity business can wipe out everything.
Exit planning requires structure. The difference between selling stock and selling assets can be millions in tax.
This is where multi-entity planning becomes relevant—not as a loophole, but as a recognition that different activities have different optimal structures.
The Operating Company / Holding Company Model
The fundamental multi-entity structure separates operations from assets.
The Basic Setup
Operating Company (OpCo): Runs the business, employs staff, signs contracts with customers, takes on operational liability.
Holding Company (HoldCo): Owns the operating company, holds real estate, manages intellectual property, accumulates excess cash.

Business OperationsWhy This Structure
Liability insulation: Operational liability stays in OpCo. HoldCo’s assets—real estate, equipment, cash reserves—are shielded from OpCo claims.
Tax-efficient transfers: Cash moves from OpCo to HoldCo through various mechanisms (distributions, management fees, rent). Once in HoldCo, it’s protected and can be invested.
Exit flexibility: You can sell OpCo while retaining HoldCo assets. Or sell HoldCo for capital gains treatment while OpCo continues with new ownership.
Estate planning: Transferring HoldCo interests to family is cleaner than transferring messy OpCo interests.
The Tax Elections
Typically:
- OpCo: S-Corp election (employment tax savings, pass-through)
- HoldCo: Disregarded entity or S-Corp depending on activities
But the optimal structure depends heavily on state law, your specific situation, and future plans. This is firmly “consult a professional” territory.
Real Estate Separation
If your business owns real estate—office building, warehouse, retail space—a separate entity is almost always the right structure.
The Property Management Model

Property LLC Operating Company

Lease AgreementThe property LLC owns the real estate. The operating company leases the space at fair market rent. Rent is deductible to OpCo, income to the property LLC.
Why Separate Real Estate
Liability protection: A slip-and-fall at your office shouldn’t reach your operating company’s bank accounts. And vice versa—business creditors can’t automatically seize the real estate.
Depreciation optimization: Real estate depreciation flows to you personally (through the pass-through) while the operating company pays deductible rent.
Exit optionality: Sell the business, keep the real estate. You become the new owner’s landlord. Continued income stream, capital gains deferral on the property.
Financing flexibility: Lenders often prefer lending against real estate in a single-purpose entity. Cleaner collateral, cleaner loan.
The Rent Calculation
The IRS will scrutinize related-party rent. It must be fair market value—what an unrelated party would pay for similar space.
Document your rate determination:
- Comparable market rents in the area
- Square footage and amenities
- Commercial lease terms
Inflated rent is a red flag. Below-market rent leaves money on the table. Fair market rent is the target.
Intellectual Property Holding Companies
For businesses with valuable IP—software, trademarks, patents, content libraries—a separate IP holding entity can be advantageous.
The Structure
You

IP HoldCo (Delaware/Nevada)

License Agreement

Operating CompanyIP HoldCo owns the intellectual property. OpCo licenses it back for a royalty. Royalty is deductible to OpCo, income to IP HoldCo.
The Benefits
Asset protection: IP is shielded from operating company liabilities.
State tax arbitrage: Delaware and Nevada don’t tax royalty income. If OpCo is in a high-tax state, royalty payments can shift income to a no-tax jurisdiction.
Sale preparation: Clean IP ownership simplifies due diligence. Acquirers often want to buy IP separate from operations.
The Risks
State nexus: Many high-tax states have anti-abuse rules (add-back statutes) that deny deductions for related-party royalties.
IRS scrutiny: Transfer pricing rules require arm’s-length royalty rates. Unjustified rates invite adjustment and penalties.
Substance requirements: IP HoldCo needs genuine business purpose and activity, not just a mailbox.
This structure works for some businesses and is problematic for others. State-specific analysis is essential.
Management Company Structures
When you operate multiple related businesses, a management company can provide shared services efficiently.
The Model
You
|
Management Company
/ | \
Biz 1 Biz 2 Biz 3Management company provides:
- Shared administrative staff
- Accounting and bookkeeping
- HR and payroll
- Marketing services
- Executive management
Each operating company pays management fees at cost-plus markup.
Why This Works
Efficiency: One payroll team, one accounting system, one HR function serving multiple entities.
Liability isolation: Each operating entity’s liability is contained. Management company assets are protected.
Employment simplification: All employees work for management company. Operating companies don’t need separate payroll, benefits, workers’ comp.
Profit allocation flexibility: Management fee rates (within arm’s-length bounds) can shift income between entities based on tax characteristics.
Documentation Requirements
- Formal service agreements
- Time tracking for shared staff
- Market-rate fee justification
- Separate books for each entity
Sloppy documentation kills management company benefits. The IRS will recharacterize informal arrangements.
The 199A Deduction Strategy
The Qualified Business Income (QBI) deduction—20% off qualifying pass-through income—has limitations that multi-entity planning can address.
The Specified Service Trade or Business (SSTB) Problem
SSTBs (law, accounting, consulting, health, financial services) face QBI phaseouts:
- Married filing jointly: phases out $383,900-$483,900
- Single: phases out $191,950-$241,950
At full phaseout, these businesses get zero QBI deduction.
The Wage/Capital Limitation
Even non-SSTB businesses face a limitation based on:
- 50% of W-2 wages paid, OR
- 25% of wages + 2.5% of qualified property
At high income levels, insufficient wages or property basis reduces the deduction.
Multi-Entity QBI Planning
Separate SSTB from non-SSTB: If your consulting firm also sells software products, separating them allows the software entity’s income to potentially qualify for QBI while consulting income does not.
Optimize wage allocation: Paying yourself through a management company (which then allocates services to operating entities) can affect wage calculations for QBI purposes.
Property planning: The 2.5% of qualified property component makes real estate holding entities particularly interesting for QBI optimization.
Important Caveat
QBI planning is complex and heavily scrutinized. Aggregation rules, anti-abuse provisions, and the specific facts of your situation all matter. This is not DIY territory.
Implementation Considerations
Costs
Multi-entity structures aren’t free:
| Item | Annual Cost Range |
|---|---|
| State filing fees (per entity) | $50-$800 |
| Registered agent (per entity) | $50-$300 |
| Additional tax returns | $500-$2,000 each |
| Legal maintenance | $1,000-$5,000 |
| Accounting complexity | $2,000-$10,000 |
For a three-entity structure, expect $5,000-$20,000 in annual administrative costs. The tax savings need to materially exceed this—typically $30K+ savings minimum to justify the complexity.
Timing
New businesses: Easier to establish multiple entities from the start. Moving assets between entities later creates taxable events.
Existing businesses: Asset transfers require careful planning. Real estate transfers may trigger reassessment. IP transfers have tax implications.
Pre-exit: Clean structure 3-5 years before a sale. Last-minute restructuring doesn’t achieve intended results and attracts scrutiny.
The Substance Requirement
Every entity must have legitimate business purpose beyond tax savings. Courts and the IRS apply economic substance doctrine to disregard arrangements that exist only on paper.
Each entity needs:
- Separate bank accounts
- Distinct operational activities
- Proper governance (meetings, minutes, resolutions)
- Arm’s-length dealings with related parties
- Genuine business rationale documented at formation
When Multi-Entity Is Not the Answer
Sometimes simple is better:
Income below $300K: Administrative costs often exceed benefits. Single S-Corp is usually sufficient.
Low liability risk: If your business model has minimal legal exposure, liability protection arguments weaken.
Simple operations: One location, one business line, no real estate—complexity isn’t justified.
Short time horizon: If you’re selling or closing within 2-3 years, restructuring costs won’t be recouped.
No professional guidance: DIY multi-entity structures usually fail. If you can’t afford ongoing professional guidance, you can’t afford the structure.
The Professional Team
Advanced entity planning requires coordination between:
Tax attorney: Structures the entities, drafts agreements, ensures legal compliance
CPA/Tax advisor: Models scenarios, prepares returns, manages ongoing compliance
Financial advisor: Integrates with investment and estate planning
Insurance professional: Ensures liability coverage across entities
These professionals should talk to each other. A structure that works for tax purposes but creates insurance gaps isn’t actually working.
The Decision Framework
Before pursuing multi-entity structures, work through:
-
What problem am I solving? Tax savings? Asset protection? Exit planning? Clear objectives focus the structure.
-
What’s the realistic savings? Model the tax impact with professional help. Include all costs.
-
What’s the operational impact? More entities mean more complexity. Can your team handle it?
-
What’s the timeline? Benefits compound over time. Short timelines rarely justify costs.
-
Do I have the right team? This requires ongoing professional guidance. Budget for it.
-
What’s the audit risk? Complex structures attract attention. Are you comfortable defending your position?
The gap between basic tax planning and sophisticated structure optimization is significant. Most business owners never need to cross it—the S-Corp election handles the heavy lifting.
But for those whose success creates new problems—income that outgrows simple structures, assets worth protecting, exits worth planning—understanding these tools matters. Not to implement blindly, but to have informed conversations with advisors about what’s possible and what’s appropriate.
The goal isn’t the most complex structure. It’s the right structure—one that balances tax efficiency, asset protection, operational simplicity, and your specific objectives. That balance looks different for every business owner, and getting it right requires professional guidance tailored to your situation.
Start the conversation with your tax advisor before you need the structure desperately. That’s when the best options become available.
