S-Corp vs. LLC in 2026: The New Math of Tax Savings in Real Estate

The Most Common Entity Question

"Should I use an LLC or an S-Corp?" is the single most common question I get. The answer used to be straightforward. Then the Big Beautiful Bill extended the QBI deduction through 2029 and shifted the payroll math. Let's sort it out.

How LLCs Are Actually Taxed

First — and this trips up more people than it should — an LLC is not a tax classification. It's a legal structure. The IRS doesn't care that you filed LLC papers with your state. What matters is how you elect to be taxed.

A single-member LLC defaults to "disregarded entity" status. You and the LLC are the same taxpayer. Rental income flows to your Schedule E. No separate tax return, no payroll, no corporate filings.

A multi-member LLC defaults to partnership taxation. Each member gets a K-1. Income flows through to personal returns. Still no entity-level tax. Still no payroll.

What matters for rental investors: Passive rental income from an LLC taxed as a disregarded entity or partnership is not subject to self-employment tax. Zero FICA. Zero Medicare surtax on the rental income itself. You collect rent, deduct expenses, take your depreciation, and report the net on Schedule E. The IRS treats it as passive income.

That's the baseline. Now let's see when an S-Corp changes the picture.

When an S-Corp Makes Sense (and When It Doesn't)

An S-Corp election means the entity files its own tax return (Form 1120-S) and pays you a "reasonable salary" for any work you do. The salary gets hit with FICA — 15.3% up to the Social Security wage base ($168,600 in 2025), 2.9% above that. But profits above the salary pass through as distributions, which skip FICA.

The pitch sounds good: pay yourself $62,000 in salary, take $83,000 in distributions, and save 15.3% on that $83,000. That's $12,699 in FICA savings.

But here's the problem for rental investors. Your rental income is already passive. It's already exempt from self-employment tax in an LLC. The S-Corp saves you nothing on passive rental income — it just adds complexity. You've got payroll to run, quarterly 941 filings, a separate corporate tax return, and a CPA bill that jumps from $450 to $2,200. All to save zero dollars in self-employment tax.

Where the S-Corp wins: active income. If you're flipping houses, managing properties for other investors, running a real estate brokerage, or earning consulting fees — that income is subject to self-employment tax. An S-Corp lets you split it between salary and distributions. A house flipper in Jacksonville netting $178,000 in active income who pays herself a $73,000 salary saves roughly $16,065 in FICA on the remaining $105,000.

The crossover point: Active real estate income above $63,000 to $78,000, after expenses. Below that, the payroll costs and CPA fees eat the savings. Above that, the S-Corp starts to pencil out.

The QBI Deduction: Why Structure Matters

Section 199A gives you a 20% deduction on qualified business income from pass-through entities. The Big Beautiful Bill made it permanent through 2029 (and expanded the phase-out ranges). Rental income qualifies — with conditions.

In an LLC taxed as a disregarded entity or partnership, the QBI calculation is clean. Net rental income minus depreciation flows through as QBI. Twenty percent comes off the top before your marginal rate applies. On $47,000 of net rental cash flow after depreciation, that's a $9,400 deduction. At a 32% marginal rate, you save $3,008.

In an S-Corp, the salary you pay yourself is not QBI. Only the distribution portion qualifies. If the S-Corp nets $47,000 and you take $28,000 as salary, only $19,000 counts as QBI. Your deduction drops from $9,400 to $3,800 — a $5,600 reduction. At 32%, that costs you $1,792 in extra taxes.

That's the math most people miss. The S-Corp might save you FICA on active income, but it shrinks your QBI deduction. For buy-and-hold rental investors, the LLC/partnership structure almost always produces a lower total tax bill.

Series LLCs and Multi-Property Investors

Once you've got three or four properties, liability isolation becomes a real question. Do you form a new LLC for each property? That's clean but expensive — filing fees, registered agents, annual reports. In Texas, a single LLC costs about $300 to file. Four properties means four LLCs: $1,200 in formation fees plus $1,200+ in annual franchise tax.

Series LLCs offer an alternative. Available in Texas, Delaware, Illinois, Nevada, and about a dozen other states, a Series LLC creates one parent entity with individual "series" — each acting as its own liability compartment. One filing fee. One annual report. Each property sits in its own series, and a lawsuit against Series A can't touch Series B's assets.

The catch: Not every state recognizes Series LLCs. If your property is in Ohio but your Series LLC was formed in Texas, an Ohio court might not honor the liability separation. The law is still developing. Get a real estate attorney in the property's state to confirm before relying on it.

The savings are real for the right investor. Instead of $2,800+ per year in multi-LLC maintenance, you're paying $500 to $800 for one Series LLC. At 5+ properties in a series-friendly state, the math works.

The Decision Framework

Buy-and-hold rental investor — collecting rent, taking depreciation, holding for cash flow? Use a single-member LLC or partnership LLC for each property (or a Series LLC if your state supports it). Skip the S-Corp. Your rental income is passive. The S-Corp adds cost without saving tax.

Earning active income — flipping, wholesaling, managing properties for clients, consulting — and that income exceeds $78,000 net? The S-Corp election is worth exploring. Run the numbers with your CPA. Compare the FICA savings against the reduced QBI deduction, the payroll costs, and the extra tax prep fees.

Doing both? Keep them in separate entities. Rentals in LLCs. Active business in an S-Corp. Don't mix passive and active income in the same entity. It muddies your QBI, complicates your capital gains treatment, and gives the IRS a reason to look closer.

One more thing. Entity choice is both a tax question and a legal question. The tax answer might say LLC. The liability answer might say Series LLC. The lending answer adds another wrinkle — some lenders won't lend to LLCs or require personal guarantees regardless. Talk to a CPA and an attorney. Not one or the other. Both.
