While S-Corps have significant tax advantages, they do have some limitations compared to partnerships and C-Corps. But the good news is, we have a tax structure that combines the advantages of all three entity structures.
Entity structures are not one size fit all. There are pros and cons to how you structure your business for tax purposes.
In this post, will show you our #1 tax structure that allows you to contribute to fringe benefit plans while maintaining a structure that is tax efficient and has all the employment tax advantages of an S-Corporation. Let’s get started.
Efficient Entity Structuring
I understand that this structure is complex and will result in higher tax preparation fees. But if you have a good CPA who can assist you, it can be a home run. Thankfully, tax preparation fees are tax deductible, which is not the case for federal income tax.
First of all, this structure involves three distinct tax entities. Each entity has unique tax characteristics.
The structure starts off with an LLC that is taxed as a partnership. In order to meet the definition of a partnership, you must have two or more partners. In this case you will have two partners: (1) a C Corp. and (2) an S Corp.
All business income should flow into this top level partnership. In addition, all business expenses relating to this income would be recorded at this level. The partnership then acts like a “funnel” and is able to allocate income to the different partners based on net income and guaranteed payments.
Using an S-Corp & C-Corp
The S corporation usually holds 70% to 80% of the ownership interest. The C corporation owns the remaining 20% to 30% of the LLC.
The LLC allocates most of the income to the S corporation. This income allocation limits payroll taxes on the S corporation’s share. The C corporation can receive a guaranteed payment for specific services it provides. This payment justifies the C corporation’s active participation in the business.
The C Corp. and S corporation officers must receive reasonable compensation for the work they provide to the business. So, payroll must be processed to each of the corporations, but is not required at the partnership level.
Because payroll is processed to both corporations, it can result in Social Security taxes applied in excess of the annual limit. To avoid this, a common paymaster handles payroll for both corporations. Using a common paymaster effectively treats the two entities as one entity for payroll purposes, thus preventing double Social Security tax obligations. Without a common paymaster, the IRS will treat each entity’s wages separately. This will cause overpayment of Social Security taxes.
Most income flows to the S corporation, which pays reasonable salaries. Remaining S corp income is not subject to payroll taxes. This boosts tax efficiency by avoiding unnecessary employment taxes. Some income is allocated to the C corporation for strategic benefit use. The C corporation can use fringe benefits not available to S corporations. These benefits include Section 105 plans and other tax-free reimbursements.
The C corporation deducts these expenses on its corporate return. This reduces its taxable income while providing non-taxable value to its employee-owner. This blend of entities allows customized benefit and tax strategies. It provides flexibility and optimization for high-income business owners.
Economic Substance Doctrine
This tax structure must comply with the economic substance doctrine. The doctrine prevents tax avoidance through transactions lacking real business purpose. It has two main requirements to pass IRS scrutiny. First, the transaction must meaningfully change the taxpayer’s economic position. Second, the transaction must have a substantial non-tax business purpose. Simply saving taxes is not a valid standalone reason.
Use EMPARION PLANS on

For this structure to hold up, services must be legitimate. The C corporation must provide actual services to the LLC. Documentation of these services should be clear and consistent. Compensation paid to the C corporation must reflect fair market value. The S corporation must also serve a genuine operational role. Each entity should have economic relevance and operate independently.
In summary, this hybrid structure merges efficiency and compliance. It maximizes tax savings while supporting business needs and benefit programs. When properly implemented, it offers a powerful and flexible tax solution.
Final Thoughts
This tax structure offers a blend of flexibility, efficiency, and savings. By separating ownership between S Corp and C Corp, taxes can be reduced significantly. Fringe benefits through the C Corp add even more value.
Still, the IRS is highly aware of abusive structures. Success depends on real business purpose, accurate records, and ongoing compliance. Business owners must work with advisors to maintain substance and stay within legal guidelines. Used properly, this strategy can support both tax efficiency and long-term business goals.
