Rental Property Setup: Should You Choose a C Corp or S Corp in 2025? The Entity Decision That Dictates Your Real Estate Tax Outcome

Ask any real estate investor with $500,000+ in property: The way you structure your rental property business can determine whether you keep or lose tens of thousands each year. Yet, nearly 73% of landlords still rely on old information, setting up their rental portfolios in the wrong type of corporation and overpaying the IRS and California Franchise Tax Board—often for decades. If you’re considering a rental property set up a c corp or s corp, the stakes are higher than most investors (and their CPAs) realize in 2025.

Bottom Line: S Corps can create a tax windfall for certain active real estate investors—while C Corps almost always spell disaster for long-term residential rental holders due to double taxation and state-specific traps. But there are crucial exceptions and strategies that radically change the math for high-net-worth individuals or those planning a portfolio sale.

This article gives you an action-first, myth-busting breakdown for 2025 based on IRS rules, real savings scenarios, and a KDA case study that exposes both the traps and the potential. Read on if you’re a landlord, real estate syndicator, LLC owner, or planning to scale with outside capital.

Quick Answer: Which Is Better for Rental Properties—C Corp or S Corp?

For the vast majority of residential rental property owners, using a C Corporation to hold rentals creates unnecessary double taxation and state-level friction you could otherwise avoid. S Corps allow for pass-through taxation, typically resulting in lower effective tax rates. However, both structures are hybrids—neither is a magic bullet, and the wrong choice can create audit risks, denied deductions, or major tax bills at exit. Always rely on specifics—not one-size-fits-all rules.

When you evaluate a rental property set up a c corp or s corp, the first decision point is tax layering. A C Corp pays its own 21% federal tax under IRC §11, and when profits are distributed, the shareholder pays again under §1(h)(11). In contrast, an S Corp bypasses this second layer via Subchapter S rules—profits flow through to Form 1040 Schedule E, taxed once at your individual rate. That’s why most passive landlords avoid C Corps unless there’s a specific liquidity or employee-benefit reason.

How Entity Choice Impacts Taxation for Your Rental Portfolio in 2025

The IRS treats C Corps and S Corps in fundamentally different ways when it comes to real estate rental income. Let’s untangle what actually happens at tax time with each:

• C Corporation: The rental business files its own tax return (Form 1120), pays a flat 21% federal tax on profits (plus California’s additional 8.84%), then owners pay a second layer of tax on dividends when profits are distributed. The result: effective rates often exceed 32-37%—even before state taxes on distributions.
• S Corporation: The S Corp is a “pass-through” entity. All rental profits flow to the shareholders’ personal returns (Form 1040, via Schedule E), taxed once at the individual level, without a separate entity-level federal tax. Owners only pay “reasonable compensation” on salary income if they provide material services, but rental income itself generally isn’t subject to self-employment tax.

Strategically speaking, the rental property set up a c corp or s corp question changes once you cross into multi-property or cross-state ownership. The IRS allows entity restructuring under Form 8832 (entity classification election), but California layers on its 8.84% franchise tax and $800 minimum fee. That means a C Corp may look clean on paper but can easily erode 10–15% of your net return before personal tax even hits. Smart investors run a side-by-side model using real projected rents, depreciation schedules, and exit timing before finalizing structure.

As an example, suppose an LLC holds three rental homes generating $150,000 net profit in Los Angeles. As a C Corp, the company pays $31,290 in federal corporate tax (21%), then shareholders owe individual tax when the remaining $118,710 is distributed as a dividend—triggering another 15-23.8% + CA tax, often totaling $12,000-$25,000 more. As an S Corp, all $150,000 is reported on the owners’ personal return, taxed at their marginal rate with no second tax layer.

KDA Case Study: Real Estate Investor Leaves C Corp, Saves $41,200 with Entity Conversion

Angela, a Bay Area tech executive, acquired six single-family rentals through a C Corporation in 2017, following her old accountant’s advice. By 2024, her rentals produced $290,000 in net income annually. Each year, Angela’s corporation paid $61,683 in combined federal and state taxes—and when she took distributions, she lost another $18,450 in personal dividend taxes per year. Total lost to taxes: $80,133 annually on under $300K of pre-tax profit.

Angela engaged KDA in early 2025. Our team reviewed her structure, then orchestrated a tax-free liquidation and S Corp conversion. In her first year post-conversion, she paid only her personal effective rate (35% CA + federal marginal), resulting in $41,200 saved—even after accounting for conversion and advisory costs.

This move also prepped Angela’s portfolio for a clean 1031 exchange and provided clean records for future financing. Her consulting fee: $12,000, yielding a net ROI of nearly 3.5x in year one. Angela says: “I paid almost $300,000 too much in taxes before KDA fixed it. I only wish I’d switched years earlier.”

S Corps for Active Flipping vs. Long-Term Renting: The True Rulebook

If you buy, rehab, and sell properties (property flipping), the IRS considers you an “active dealer”—not merely a passive landlord. S Corps benefit active flippers because their profits are subject to self-employment taxes, but the S Corp structure allows for ‘reasonable salary’ and the rest as pass-through distribution, cutting self-employment tax exposure. That said, S Corps rarely fit pure rental investors because:

• Rental income itself is not considered “active” business income. Placing rental property in an S Corp may create trapped equity problems and jeopardize the coveted Section 1031 exchange for capital gains deferral.
• S Corps can create headaches on later property sales: Depreciation recapture and gain is allocated to shareholders and may not get full capital gain treatment depending on years held and shareholder changes.
• If an investor wants to admit new partners or sell shares, the S Corp structure is often rigid, forced to respect one class of stock and block foreign/corporate investors.

For pure hold-and-rent portfolios, most experts (including KDA) prefer LLCs (taxed as partnerships/disregarded) for ultimate flexibility—not S or C Corps. But exceptions do exist for complex, multi-state, or syndication situations.

Why Most Investors Miss Out: Misconceptions, IRS Traps, and California Gotchas

Red Flag Alert: The biggest mistake? Believing that C Corps protect you from audit or that S Corps are always compliant with California’s nuanced rules. The FTB can penalize mismatched filings, and the IRS often recharacterizes S Corp “distribution” payments as disguised salary, triggering payroll tax audits.

Common misconceptions:

• Myth: “If I put my rentals in a C Corp, I’ll look more professional to banks.”
  Truth: Most lenders prefer to see individual, LLC, or partnership ownership. C Corps create more paperwork—not more trust.
• Myth: “S Corps make sense for every type of real estate business.”
  Truth: S Corps work best when you operate a services business or flip properties—not for passive rental income, due to double taxation at sale and loss limitation issues.

Pro Tips for Getting Your Structure Right—and the IRS Forms No One Fills Out

Too often, investors miss out on thousands in annual tax savings and lose sleep over “what if my entity is wrong?” Here’s how to avoid rookie errors or costly do-overs:

• Never try to change entity classification after the first year unless you’re prepared to face built-in gains tax and revaluation issues—see IRS Form 2553 for S Corp elections.
• If you must use a corporation, document every dollar of capital infusions, member loans, and distributions. California’s FTB will scrutinize these events (see CA Form 100 guidance).
• For rental LLCs taxed as S Corps, make “reasonable salary” determinations using IRS guidelines. Document the time spent actively managing versus passive ownership, as failure here can result in reclassification and tax penalties.

Pro Tip: Run periodic “tax entity stress tests” every two years—especially after major acquisitions, sales, or partnership changes.

Frequently Asked Questions from Real Estate Investors

Should I ever put rental property into a C Corp?

In rare cases, yes—but only when: (1) you need complex employee benefits best delivered via C Corp, (2) your business is planning an IPO or major venture capital involvement, or (3) you want to shield future profits from personal tax until sale. Even then, understand the sale of appreciated real estate inside a C Corp almost always results in double tax.

High-income investors analyzing a rental property set up a c corp or s corp should think in terms of “exit taxes,” not just annual filings. When appreciated real estate is sold inside a C Corp, IRC §311(b) triggers recognition of gain at the corporate level, and the shareholder faces another tax upon distribution. An S Corp or LLC structure, by contrast, lets you defer gain via a §1031 exchange and potentially qualify for long-term capital gain treatment. That’s the hidden $100K+ swing most C Corp landlords miss until it’s too late.

Can my S Corp own an LLC that holds rental property?

S Corps can be members of LLCs, but limitations on ownership type, classes of members, and state-specific rules make this a high-risk area. Consult a strategist before structuring a multi-entity ecosystem.

How do California rules differ from federal ones?

California’s Franchise Tax Board can create “phantom income” or franchise tax vulnerabilities if your S Corp misclassifies income or fails to observe formalities. Always use both federal and California-specific guidance.

Action Steps: Building Your Tax-Smart Real Estate Structure in 2025

Here’s how to protect yourself and maximize your after-tax profits this year:

• Review your current entity: If your rentals are in a C Corp, calculate your true effective tax rate and model potential outcomes if you converted.
• If considering an S Corp, assess whether you (a) materially participate, (b) plan to add partners, or (c) are likely to need 1031 deferment soon. S Corps are optimal only for active, small-crewed operations who want tax-efficient salary splits.
• Consult an advisor before making any change—conversion, sale, or reorganization involves multiple IRS forms (2553, 8832) and state documents.
• Annually revisit your structure as your portfolio, capital base, and risk tolerance evolve. What was ideal at 10 doors may be disastrous at 30.
