If you’re deciding between an LLC or S Corp for flipping houses, start with a standard LLC and elect S Corp taxation later, once your annual profit consistently clears roughly $40,000 to $50,000. Both structures give you the same liability shield. The difference is payroll tax: the S Corp election can save thousands a year on self-employment tax, but it adds real administrative costs that swallow the savings at lower profit levels.
Before you pick either one, there’s a tax classification issue that reshapes what any entity choice can do for you.
The IRS Treats Flippers as Dealers, Not Investors
Investors buy property to hold for rent or long-term appreciation. Dealers buy to resell at a profit. If you’re renovating and selling quickly, you’re a dealer, and the properties are inventory.
Two consequences follow, and they apply whether you operate as a standard LLC or as an S Corp. Flipping profits are taxed as ordinary income, not at long-term capital gains rates. And properties held primarily for sale are explicitly excluded from 1031 like-kind exchanges, so you cannot defer tax by rolling proceeds into the next property the way a buy-and-hold investor can.1Office of the Law Revision Counsel. 26 USC 1031 – Exchange of Real Property Held for Productive Use or Investment No entity choice changes that baseline.
How a Standard LLC Taxes Your Flip Profits
A single-member LLC is a disregarded entity for federal tax purposes. The business pays no income tax of its own; profits and losses flow to your personal return on Schedule C. A multi-member LLC files Form 1065, and each member picks up their share on a Schedule K-1.2Internal Revenue Service. LLC Filing as a Corporation or Partnership Either way, there’s no double taxation.
The cost is self-employment tax. LLC members owe self-employment tax on their share of earnings.3Internal Revenue Service. Single Member Limited Liability Companies The combined rate is 15.3% (12.4% Social Security plus 2.9% Medicare), but it’s not applied to your full net income. You first multiply net earnings by 92.35%, then apply the 15.3%.4Office of the Law Revision Counsel. 26 USC 1402 – Definitions
On $100,000 in flipping profit, that’s roughly $14,130 in self-employment tax, on top of your regular income tax. That bill is what sends flippers looking at the S Corp election once profits grow.
What the S Corp Election Changes
An S corporation isn’t a separate entity type. It’s a tax classification you elect by filing Form 2553. Your LLC stays an LLC for liability purposes; only the tax treatment changes.5Internal Revenue Service. S Corporations
Once elected, you split your income into two buckets. You pay yourself a W-2 salary, which carries the full 15.3% in payroll tax (split between the employer and employee halves). Everything above that salary comes out as a shareholder distribution, which is not subject to Social Security or Medicare tax.6Internal Revenue Service. S Corporation Employees, Shareholders and Corporate Officers That gap is where the savings come from.
Most single-member and spouse-owned flipping LLCs meet the S Corp eligibility rules without any changes.5Internal Revenue Service. S Corporations
The Reasonable Salary Requirement
You can’t pay yourself a token $10,000 salary and take $90,000 as distributions. Courts have consistently ruled that S Corp shareholder-employees who provide more than minor services must receive reasonable compensation, and attempts to disguise wages as distributions don’t survive scrutiny.7Internal Revenue Service. Wage Compensation for S Corporation Officers
The IRS weighs factors like your training and experience, the hours you put into sourcing deals and managing renovations, what comparable businesses pay for similar work, and the breadth of your duties. For a full-time flipper managing multiple projects, a defensible salary in many markets lands between $40,000 and $70,000, depending on experience and local pay scales. A CPA with real estate experience can help you set a number that holds up.7Internal Revenue Service. Wage Compensation for S Corporation Officers
What the Switch Actually Saves You
Take $100,000 in flipping profit.
As a standard LLC: $100,000 × 92.35% × 15.3% comes to roughly $14,130 in self-employment tax.8Internal Revenue Service. Self-Employment Tax (Social Security and Medicare Taxes)
As an S Corp with a $50,000 salary: payroll tax on the salary is $7,650 (15.3% × $50,000), and the remaining $50,000 taken as a distribution carries no payroll tax. That’s roughly $6,480 saved versus the standard LLC.
The savings grow with profit, but there’s a ceiling. Social Security tax only applies to earnings up to $184,500 in 2026.9Social Security Administration. What Is the Current Maximum Amount of Taxable Earnings for Social Security Above that cap, only the 2.9% Medicare portion continues, so per-dollar savings shrink once your salary clears it. If you’re earning well above that level, the additional 0.9% Medicare tax on wages over $200,000 (single) or $250,000 (married filing jointly) is also worth factoring in with a tax professional.
What the S Corp Election Costs To Run
The election isn’t free. You need to run actual payroll, which means paying for a payroll service (typically $20 to $180 per month plus per-employee fees) or handling quarterly deposits yourself. You file Form 941 quarterly to report withheld payroll taxes and the employer’s share.10Internal Revenue Service. About Form 941, Employer’s Quarterly Federal Tax Return At year end you issue yourself a W-2 and file Form 1120-S instead of the simpler Schedule C. Most flippers hire an accountant for the 1120-S, which runs $500 to $1,500 more per year than a basic Schedule C return.
Add payroll service fees, the extra accounting cost, and the time spent on compliance, and the S Corp adds roughly $2,000 to $4,000 in annual expenses.
The QBI Deduction Complicates the Math
The qualified business income (QBI) deduction lets owners of pass-through businesses deduct up to 20% of qualified business income from taxable income. The One Big Beautiful Bill Act, signed in July 2025, made the deduction permanent.11Office of the Law Revision Counsel. 26 US Code 199A – Qualified Business Income Standard LLCs and S Corps both qualify, but the mechanics differ.
When you elect S Corp taxation, your W-2 salary does not count as qualified business income. The statute specifically excludes reasonable compensation paid by a qualified trade or business.11Office of the Law Revision Counsel. 26 US Code 199A – Qualified Business Income Only the K-1 profit above your salary qualifies. With a standard LLC, all net income is potentially eligible for the 20% deduction.
That creates a real tension with the payroll tax strategy. A higher salary shrinks your QBI base; a lower salary shrinks your self-employment tax savings and raises the reasonable-compensation risk. The optimal split depends on your total income, filing status, and whether you’re above the phase-out thresholds ($200,000 for single filers and $400,000 for married filing jointly in 2026). A tax professional who works with real estate dealers can model the tradeoff for your actual numbers.
Profit Thresholds for Choosing
The choice is really a question of when, not which. Use these benchmarks:
- Under $40,000 in annual profit: stay with the standard LLC. Administrative costs eat most of the S Corp savings, and simpler filings let you focus on growing the business.
- $40,000 to $75,000: run the numbers with a CPA. The S Corp election likely nets a saving after costs, but the margin depends on your reasonable salary and how QBI interacts with your household income.
- Above $75,000: the S Corp election typically produces clear savings. At $150,000 in profit with a $60,000 salary, you could save $10,000 or more a year in payroll taxes after compliance costs.
For a first-year flipper working one or two projects, the standard LLC is almost always the right starting point. The simplicity is worth the extra self-employment tax while you’re still figuring out whether the business will produce consistent income.
Liability Protection Is the Same Either Way
The liability shield comes from the LLC itself, not the tax election. Whether the LLC is taxed as a disregarded entity, a partnership, or an S Corp, lawsuits from construction defects, buyer claims, or contractor disputes hit the business first, not your personal accounts.
That protection only holds if you respect the boundary between yourself and the business. Courts can pierce the veil and hold you personally liable when the LLC is treated as an extension of the owner rather than a separate entity.12Legal Information Institute. Piercing the Corporate Veil The most common way flippers lose the shield is by commingling funds: paying personal expenses from the business account, depositing flip proceeds into a personal account, or failing to keep clean books. A dedicated business bank account, separate books, and documented transactions go a long way toward keeping the veil intact.
Mind the March 15 Deadline
Form 2553 must be filed no more than two months and 15 days after the beginning of the tax year you want the election to take effect, or at any time during the preceding tax year.13Internal Revenue Service. Instructions for Form 2553 For a calendar-year business, that’s March 15. If you have a strong year and realize in October that S Corp taxation would have saved you money, you’re waiting until the following year. A CPA who specializes in real estate can pinpoint the crossover for your income level, filing status, and state tax picture before the deadline passes.
