PARTNERSHIP OR S CORPORATION?

A Case Study for a Multi-Investor Real Estate Venture

Capital Waterfalls • Sweat Equity • Special Allocations • Mortgage Basis • Refinancing • Succession

By Alex Oware, CPA and Tax Attorney

Wondering whether a multi-investor real estate LLC should remain a partnership or elect S corporation status? This case study presents the complete fact pattern first, identifies what the owners are trying to accomplish, and then walks through the tax consequences one issue at a time. The purpose is not to declare that every rental property must use a partnership. The purpose is to show why an S corporation becomes a poor fit when the owners intentionally use different capital, profit, loss, service, and liquidation economics.

Here is the case study we are examining today:

The Facts, Stated Clearly

The venture uses 1,000 ownership units and assigns the following ownership percentages:

The owners do not fund property acquisitions in those same percentages. For down payments and closing costs, they contribute cash as follows:

The operating agreement also separates ordinary cash flow from property-sale proceeds:

• Operating cash flow, including the proposed distribution of cash-out refinancing proceeds, follows ownership: 50% / 25% / 25%.
• Property-sale or liquidation proceeds first return each investor’s actual acquisition capital. Only after that return of capital does the remaining profit follow 50% / 25% / 25%.
• Acquisition-related losses are intended to follow 25% / 37.5% / 37.5%, while operating profits follow 50% / 25% / 25%.
• The Managing Investor’s service-based ownership does not receive a return of contributed cash because no cash is contributed for that portion.
• The venture maintains an initial reserve of $7,000 and a minimum reserve target of $5,000 before ordinary distributions.
• When one investor cannot meet a capital call, another investor may advance the shortfall at prime plus 2%, with repayment from future distributions.
• The owners want the arrangement to remain workable for future heirs who may inherit interests but may not always have cash available for major repairs or capital calls.

The Questions the Owners Need Answered

1. Does an S corporation provide a meaningful double-tax advantage over partnership taxation?
2. Can the S corporation one-class-of-stock rule coexist with the two-tier capital waterfall?
3. Can the owners call acquisition capital “shareholder loans” and preserve the intended economics?
4. Can the partnership allocate profits 50% / 25% / 25% but losses 25% / 37.5% / 37.5%?
5. How should the Managing Investor’s sweat equity be structured?
6. How do mortgage debt, depreciation, refinancing, property distributions, buyouts, and death affect the two structures?
7. What filing and operating-agreement steps are required before the venture acquires property?

First, Understand the Two Tax Classifications

A domestic LLC with two or more members is generally classified as a partnership unless it elects corporate treatment. A partnership files Form 1065, issues Schedules K-1, and passes its taxable items through to its partners. The partnership itself generally does not pay federal income tax under IRC §701.

An eligible domestic entity can elect to be taxed as an S corporation. The S corporation also passes income, losses, deductions, and credits through to shareholders. It must, however, satisfy the shareholder-eligibility rules, the 100-shareholder limit, and the one-class-of-stock rule under IRC §1361.

Authorities: Treas. Reg. §301.7701-3(b)(1); IRC §§701, 1361, and 1362; IRS Instructions for Forms 1065 and 2553.

1. Both Choices Are Pass-Throughs, So the S Election Does Not Solve a Double-Tax Problem

The owners are not choosing between a partnership and a C corporation. They are choosing between two pass-through systems. Under both systems, taxable income can reach the owners even when the entity retains cash.

Assume the venture earns $120,000 of taxable rental income and distributes only $60,000 because it retains the balance for a roof reserve. The owners still report their shares of the full $120,000 under either classification. The retained cash does not create a second federal income tax merely because the entity keeps it.

The practical difference is flexibility. Partnership rules can accommodate properly structured special allocations and capital waterfalls. S corporation rules generally cannot attach different distribution or liquidation rights to different shares.

Authorities: IRC §§701, 1361, and 1366; IRS, About Form 1065; IRS, S Corporations.

2. The Owners Intentionally Use Different Ownership and Funding Percentages

The Managing Investor owns 50% because the arrangement rewards both cash and services. Yet the Managing Investor supplies only 25% of acquisition cash. The two cash investors jointly supply 75%. This difference is a business term, not an accounting error.

The arrangement therefore contains two economic measurements:

• Who supplies cash and bears acquisition risk: 25% / 37.5% / 37.5%.
• Who participates in ordinary operating upside after accounting for services: 50% / 25% / 25%.

Partnership taxation permits those measurements to coexist if the operating agreement, capital accounts, allocations, and liquidation provisions consistently reflect the bargain. S corporation stock generally does not.

Authorities: IRC §704(a)-(b); Treas. Reg. §1.704-1; IRC §1361(b)(1)(D).

3. The Two-Tier Sale Waterfall Conflicts With S Corporation Stock Rights

An S corporation has one class of stock only when all outstanding shares confer identical rights to distribution and liquidation proceeds. The analysis focuses on the governing provisions, not merely on what the owners call a payment.

A single mistaken disproportionate payment does not automatically create a second class of stock when the governing documents provide identical rights. Here, however, the operating agreement intentionally grants different rights: first a capital return based on cash contributed, then a profit split based on ownership.

Authorities: IRC §1361(b)(1)(D); Treas. Reg. §1.1361-1(l); Rev. Proc. 2022-19.

Downside example: the property loses value

Assume the owners contribute $400,000 and a later sale leaves only $300,000 after debt and closing costs.

The partnership waterfall causes each investor to recover 75% of the cash actually contributed. The S corporation result pays the Managing Investor $50,000 more than the Managing Investor contributes even though the property loses money. Each cash investor recovers only half of a $150,000 contribution. That is not the deal the owners describe.

Profitable example: the capital is fully recovered

Assume a sale leaves $600,000. The partnership first returns $400,000 of capital and then divides the $200,000 profit 50% / 25% / 25%.

The partnership result protects the investors who supply the greater cash while still rewarding the Managing Investor for services through the residual profit split. The S corporation result removes that capital protection.

4. The Proposed Profit and Loss Percentages Require Partnership Allocation Rules

The venture wants operating profits divided 50% / 25% / 25% but acquisition-related losses divided 25% / 37.5% / 37.5%. An S corporation generally allocates tax items on a per-share, per-day basis under IRC §1377(a). It does not allocate half of the income to one shareholder but only one-quarter of the depreciation loss to that same shareholder.

Assume the first property produces a $120,000 tax loss from depreciation, interest, repairs, and operating expenses.

The S corporation gives half of the tax loss to the investor who supplies only one-quarter of the acquisition cash. The partnership can potentially place more of the loss with the investors who bear more of the economic downside, but only if the allocation satisfies §704(b).

Authorities: IRC §§1366 and 1377(a); IRC §704(b); Treas. Reg. §1.704-1.

5. A Partnership Special Allocation Works Only When It Changes Real Economics

Partnership flexibility is not permission to place deductions with the investor who has the highest tax rate. Section 704(b) requires substantial economic effect, or the allocation must otherwise follow the partners’ interests in the partnership.

Using the $400,000 capital example, assume the partnership allocates the $120,000 loss 25% / 37.5% / 37.5%. The §704(b) capital accounts move as follows:

The loss allocation has economic effect only if these capital-account reductions affect what the owners ultimately receive or must contribute. The agreement therefore needs coordinated provisions for capital-account maintenance, liquidation, qualified income offsets, deficit restoration where applicable, nonrecourse deductions, minimum-gain chargebacks, and book revaluations.

Authorities: IRC §704(b); Treas. Reg. §1.704-1(b)(2)-(3); Treas. Reg. §1.704-2.

6. Depreciation Follows the Same Allocation Problem

Real estate tax losses often arise because depreciation exceeds current cash flow. Depreciation is still a tax deduction that must follow the applicable allocation rules.

Assume the property generates $80,000 of rental cash before depreciation and claims $140,000 of depreciation, producing a $60,000 tax loss. The venture may distribute cash 50% / 25% / 25% while allocating the tax loss 25% / 37.5% / 37.5% only if the partnership agreement and capital-account mechanics support that result.

This illustrates why the entity choice cannot be made by comparing tax rates alone. The owners are deliberately separating current cash, capital risk, and depreciation economics.

Authorities: IRC §§704(b), 1366, and 1377; Treas. Reg. §§1.704-1 and 1.704-2.

7. The Managing Investor’s Sweat Equity Fits More Naturally in a Partnership

The Managing Investor receives part of the 50% ownership for services rather than cash. That distinction matters because a service provider can receive either a current capital interest or only a right to future profits and appreciation.

S corporation stock for services

If an S corporation issues stock for services, IRC §83 generally measures compensation by the stock’s fair market value when the interest becomes transferable or is no longer subject to a substantial risk of forfeiture, less any amount paid.

Assume the company has $1,000,000 of net equity when a 25% service-based stock interest vests. A 25% interest can carry approximately $250,000 of value. The service provider may recognize compensation income, and the corporation must consider valuation, payroll reporting, withholding, vesting, and a possible §83(b) election for restricted stock.

Partnership profits-interest approach

A partnership can often grant a qualifying profits interest that participates only in future income and appreciation. If the partnership liquidates immediately after the grant, the service provider receives nothing from the cash capital already contributed by the other investors.

This structure can protect the $300,000 contributed by the two cash investors while allowing the Managing Investor to share in future upside. The agreement must establish a clear liquidation hurdle, vesting terms, forfeiture rules, tax-distribution treatment, and consistent owner reporting.

The profits-interest safe harbor has exceptions. For example, it does not automatically apply when the interest relates to a substantially certain and predictable income stream, such as a high-quality net lease. Real estate ventures therefore require fact-specific drafting rather than a generic “profits interest” label.

Authorities: IRC §83; Rev. Proc. 93-27; Rev. Proc. 2001-43; IRS Publication 541 (2025).

8. Mortgage Debt Creates a Major Basis Advantage for Partnerships

Real estate ventures rely heavily on mortgage debt. In a partnership, a partner’s properly allocated share of partnership liabilities generally increases outside basis under IRC §752. In an S corporation, third-party corporate debt generally does not increase shareholder stock basis.

Assume the venture acquires a $1,000,000 property with $400,000 of owner equity and a $600,000 mortgage. For illustration only, assume the liability is allocated 25% / 37.5% / 37.5%.

The actual partnership debt allocation depends on whether the liability is recourse, nonrecourse, or partner nonrecourse debt. The illustration shows the structural difference: partnership liabilities can support outside basis; an S corporation’s bank mortgage generally does not support shareholder stock basis.

Adequate basis does not guarantee a current deduction. The owner must still satisfy the at-risk, passive-activity, and excess-business-loss rules. But without basis, the deduction analysis stops at the first limitation.

Authorities: IRC §§704(d), 752, and 1366(d); Treas. Reg. §§1.752-2 and 1.752-3; Treas. Reg. §1.1366-2; IRS, S Corporation Stock and Debt Basis.

9. Cash-Out Refinancing Exposes the S Corporation Basis Problem

Loan proceeds are generally not income because the borrower has an obligation to repay them. A later distribution of those proceeds must still be tested against each owner’s basis.

Assume the property appreciates, the entity borrows an additional $300,000, and the owners distribute the proceeds 50% / 25% / 25%:

In a partnership, the new liability may increase outside basis before the distribution, depending on the §752 allocation. The distribution can still create gain if cash and deemed cash from liability shifts exceed outside basis, so the transaction requires modeling.

In an S corporation, the bank borrowing generally does not increase stock basis. If the Managing Investor has only $80,000 of stock basis when receiving $150,000, the first $80,000 may reduce basis and the remaining $70,000 may be taxable gain. Debt basis from a direct shareholder loan does not protect the distribution because S corporation distributions are tested against stock basis, not debt basis.

Authorities: IRC §§731, 733, 1367, and 1368; IRS, S Corporation Stock and Debt Basis.

10. Calling the Acquisition Capital “Shareholder Loans” Does Not Recreate the Intended Equity

The owners consider documenting all acquisition contributions as loans so each lender can recover principal according to the amount advanced while S corporation distributions remain pro rata. Genuine shareholder debt can exist, but debt must operate as debt.

IRC §1361(c)(5) provides a straight-debt safe harbor for a written unconditional promise to pay a sum certain on demand or on a specified date when interest is not contingent on profits and the instrument is not convertible into stock, among other requirements.

Assume the owners document $400,000 of shareholder loans at 6%:

The entity owes $24,000 of interest each year before ordinary distributions. The lenders report taxable interest income. The notes require actual maturity terms, payment dates, creditor remedies, and conduct consistent with the documents.

When repayment depends solely on a profitable property sale, the advances remain outstanding indefinitely, the company is thinly capitalized, and the owners accept the same risk as equity investors, the debt characterization becomes vulnerable. The arrangement also becomes unnecessarily expensive and administratively complex.

Below-market loans can trigger imputed-interest rules under IRC §7872. Debt should be used for a genuine lending transaction, not merely to force partnership economics into an S corporation.

Authorities: IRC §§1361(c)(5) and 7872; Treas. Reg. §1.1366-2(a)(2); general federal debt-versus-equity principles.

11. Capital-Call Shortfalls and Heir Protection Are Easier to Draft in a Partnership

The owners want future heirs to retain their interests even when one heir cannot immediately fund a major repair. The goal is to finance a temporary shortfall without automatically stripping the heir of long-term ownership.

Assume a property needs a $90,000 roof and structural repair. Each owner is expected to provide $30,000, but one owner cannot fund the contribution. The partnership agreement can distinguish among several solutions:

• A partner lends $30,000 to the partnership. The partnership owes the lender principal and interest.
• A partner lends $30,000 personally to the nonfunding owner, who contributes the cash. The personal debt remains outside the partnership.
• The advancing partner funds the shortfall and receives repayment from the defaulting owner’s future distributions, subject to a properly drafted setoff mechanism.
• The agreement creates a preferred recovery, dilution formula, or default purchase right, subject to valuation and fiduciary safeguards.

The partnership can connect the chosen remedy to capital accounts and distribution rights. An S corporation can use genuine commercial debt arrangements, but it cannot use the “loan” label to create permanent nonidentical equity rights or routinely redirect corporate distributions contrary to the stock rights.

Authorities: IRC §1361(b)(1)(D) and (c)(5); Treas. Reg. §1.1361-1(l); IRC §704(b).

12. A Fixed Monthly Distribution Policy Can Undercapitalize the Venture

The reserve starts at $7,000 and cannot fall below $5,000 before operating distributions. That amount may be reasonable for a small initial property, but it may be inadequate for a portfolio with roofs, HVAC systems, vacancies, insurance deductibles, legal expenses, and casualty events.

Assume three properties generate $18,000 of monthly cash flow and the venture distributes all but $5,000 each month. A $45,000 HVAC and plumbing event then arises. The owners must contribute cash or borrow even though the business recently distributed funds.

A better operating agreement allows the manager to establish property-specific and portfolio-level reserves based on budgets, debt covenants, expected capital expenditures, and acquisition plans. The entity should determine whether distributions occur monthly, quarterly, or less frequently only after reviewing current financial statements and cash-flow forecasts.

13. Distributing Appreciated Real Estate Is Generally Harsher From an S Corporation

The owners want flexibility to pass properties to family members or divide assets among owners without selling every building. Corporate and partnership distribution rules differ sharply.

Assume one property has an $800,000 fair market value and a $500,000 adjusted tax basis after depreciation.

If an S corporation distributes the property to one shareholder, IRC §311(b) generally requires the corporation to recognize the $300,000 gain as though it sells the property at fair market value. The gain passes through among all shareholders under the S corporation allocation rules, even though one shareholder receives the building.

A partnership generally recognizes no gain or loss merely because it distributes property to a partner under IRC §731(b). The distributee commonly receives a carryover or substituted basis under §732. Important exceptions still apply, including cash in excess of outside basis, liability shifts, §704(c)(1)(B), §737, §751, disguised sales, and marketable-security rules.

The partnership framework therefore begins with nonrecognition and then tests exceptions. The corporate framework generally begins with gain recognition on appreciated-property distributions.

Authorities: IRC §§301, 311(b), 731, 732, 704(c)(1)(B), 737, and 751.

14. Buyouts and Death Can Produce Better Inside-Basis Results in a Partnership

A long-term family venture must address what happens when an owner sells, dies, retires, or is redeemed. Partnership taxation offers an elective mechanism that can align a transferee’s outside basis with a special adjustment to inside asset basis.

Assume an investor dies when the partnership interest is worth $500,000. The successor receives a $500,000 outside basis under the applicable transfer-at-death rules, but the successor’s share of partnership inside basis is only $300,000. A valid §754 election can create a $200,000 special §743(b) adjustment for that successor.

The adjustment may produce additional depreciation or reduce gain for the successor, depending on how it is allocated under §755. An heir to S corporation stock may receive a stock-basis adjustment, but the corporation’s basis in the underlying buildings generally does not receive a corresponding adjustment merely because a shareholder dies.

Authorities: IRC §§743(b), 754, and 755.

15. The Classic S Corporation Payroll-Tax Benefit Is Often Weak for Long-Term Rental Income

Many owners elect S corporation status because active service-business income can be divided between W-2 compensation and shareholder distributions. That strategy is less compelling when the principal income is rent from real property, which is generally excluded from net earnings from self-employment under IRC §1402(a)(1), subject to exceptions.

If the Managing Investor performs substantial management services for an S corporation and receives or is entitled to payments, the corporation must determine reasonable W-2 compensation before treating the balance as nonwage distributions. This adds payroll registration, withholding, employment taxes, quarterly filings, W-2 reporting, and compensation documentation.

A partnership also must analyze how the Managing Investor is compensated. Guaranteed payments for services and some distributive shares can have self-employment-tax consequences. The point is not that partnership compensation is tax-free. The point is that an S election does not create a clear payroll-tax win when the underlying rental income is already generally outside self-employment tax.

Authorities: IRC §1402(a)(1); IRS, S Corporation Employees, Shareholders and Corporate Officers; IRS, S Corporation Compensation and Medical Insurance Issues.

16. Starting as a Partnership Preserves Options, but a Later Conversion Requires Modeling

The owners can begin with partnership treatment and reconsider corporate taxation later if the business changes. A later election is not automatically tax-free merely because the same LLC remains in existence under state law.

A partnership-to-corporation classification change is generally treated as a deemed transfer of assets and liabilities to a corporation followed by a distribution of stock to the partners. If liabilities transferred to the corporation exceed the adjusted basis of transferred property, IRC §357(c) can trigger gain.

Assume years of depreciation reduce total asset basis to $500,000 while mortgage liabilities remain $700,000. The $200,000 excess requires a detailed §357(c) analysis before any corporate election.

If an S election is later revoked or terminated, IRC §1362(g) generally prevents a new S election before the fifth taxable year beginning after the first year for which the termination is effective, unless the IRS consents.

The §1374 built-in gains tax is primarily a former-C-corporation issue or a carryover-basis C-corporation asset issue. For a direct partnership-to-S conversion, the more immediate concerns are usually §357(c), one-class-of-stock compliance, stock basis, and future corporate property-distribution rules.

Authorities: IRC §§351, 357(c), 1362(g), and 1374; Rev. Rul. 84-111; Rev. Rul. 2004-59.

17. The Series LLC Structure Does Not Eliminate Property-Level Discipline

The venture uses a Series LLC concept and expects to acquire properties in multiple states. Federal tax classification and state-law liability protection are separate questions.

A wholly owned property subsidiary or series may be disregarded for federal income-tax purposes, allowing its activity to flow into the parent partnership return. That does not mean the owners should commingle title, bank activity, leases, insurance, deposits, expenses, or accounting records across properties.

Before each acquisition, the owners should determine whether the property state recognizes the foreign series, requires a local registration, or makes a separate state LLC more practical. Each property should have a traceable ledger, capital schedule, debt schedule, and legal ownership record even when federal tax reporting ultimately consolidates the activity.

Authorities: Treas. Reg. §§301.7701-2 and 301.7701-3; state law controls legal formation, qualification, and series recognition.

18. “No Revenue” Does Not Automatically Mean “No Partnership Return”

The venture forms before it acquires property and incurs formation-related costs. The filing question depends on whether the domestic partnership receives income or incurs expenditures treated as deductions or credits for federal tax purposes.

The current Form 1065 instructions state that a domestic partnership generally files Form 1065 unless it neither receives income nor incurs expenditures treated as deductions or credits. Formation invoices must therefore be classified as organizational costs, startup costs, syndication costs, state taxes, professional fees, or member-paid expenses.

Assume the venture pays $4,000 of legal formation fees, $1,200 of registered-agent and state charges, and $800 of tax-consulting costs. The answer does not turn solely on the absence of rent. It turns on the character and timing of those expenditures and whether the business has begun.

Authority: IRS Instructions for Form 1065 (2025), “Who Must File—Domestic Partnerships”; IRC §§195 and 709.

How the Arrangement Is Positioned More Effectively

The owners’ objectives are commercially reasonable. The problem arises only when partnership-style economics are forced into an S corporation framework. A stronger structure follows these steps:

1. Retain partnership classification. The default partnership classification most closely matches the different capital, profit, loss, service, and liquidation economics.

2. Rewrite the operating agreement around §704(b). The agreement should coordinate capital accounts, liquidation rights, special allocations, qualified income offsets, minimum-gain provisions, and book revaluations.

3. Separate cash capital from service-based upside. The Managing Investor’s service interest should be analyzed as a profits interest with a clear liquidation hurdle rather than as a right to existing contributed capital.

4. Track unreturned capital property by property. Each property schedule should show contributions, distributions, debt, depreciation, sale proceeds, and remaining unreturned capital for each investor.

5. Separate entity loans from personal loans. A loan to the partnership, a member-to-member loan, a preferred capital contribution, and a default advance are different transactions and should not share one undefined label.

6. Adopt a realistic reserve and distribution policy. Distributions should follow current financial statements, capital-expenditure forecasts, lender requirements, and acquisition plans—not a rigid monthly promise.

7. Include tax-distribution provisions. The owners may owe tax on allocated income even when the venture retains cash. The agreement should define when and how tax distributions are made.

8. Authorize §754 elections when beneficial. The agreement should permit an election after a sale, death, redemption, or qualifying distribution when the basis adjustment produces a meaningful benefit.

9. Maintain property-level legal and accounting separation. Each entity or series should maintain records that support ownership, liability isolation, capital tracking, and reliable tax reporting.

Conclusion: Let the Tax Classification Follow the Deal

An S corporation is not inherently inferior to a partnership. It can work well for a domestic operating business with eligible shareholders, simple pro rata economics, one class of equity, and a genuine reasonable-compensation strategy.

This case study presents a different arrangement. The cash investors supply 75% of acquisition equity. The Managing Investor receives additional upside for services. Capital returns follow cash contributed. Residual profits follow ownership. Losses and depreciation are intended to follow economic risk. Mortgage debt matters. The owners want flexible capital calls, refinancing, property distributions, buyouts, and multigenerational succession.

Those are partnership economics. The partnership rules can respect them when the operating agreement and tax accounting are properly designed. The S corporation rules require the owners either to abandon the waterfall or to preserve it at the risk of an invalid or terminated election.
