For most house flippers, the right answer is to start with a standard LLC and elect S Corp taxation once annual profits consistently clear roughly $40,000 to $50,000. Choosing between an LLC or S Corp for flipping houses is really a question of timing, because both structures give you the same liability shield. What differs is how the IRS taxes your profits, and the S Corp election only pays off once profits are large enough to absorb the extra payroll and accounting costs it brings with it.
The Dealer Classification Comes First
Before either structure matters, you need to know how the IRS sees your business. Flippers buy property to renovate and resell, which makes them dealers, not investors. The properties are inventory.
Two consequences follow. All 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 taxes by rolling profits into the next property.1Office of the Law Revision Counsel. 26 USC 1031 – Exchange of Real Property Held for Productive Use or Investment Neither an LLC nor an S Corp election changes any of this. Dealer status is the baseline your tax strategy has to work around.
How a Standard LLC Taxes Flipping Profits
A single-member LLC is a disregarded entity for federal tax purposes. The business itself pays no income tax; profits and losses flow through to your personal return on Schedule C. A multi-member LLC files Form 1065, and each member reports their share on Schedule K-1.2Internal Revenue Service. LLC Filing as a Corporation or Partnership
The tradeoff is self-employment tax. LLC members owe it on their share of earnings.3Internal Revenue Service. Single Member Limited Liability Companies The rate is 15.3%: 12.4% for Social Security and 2.9% for Medicare.4Internal Revenue Service. Self-Employment Tax (Social Security and Medicare Taxes) The tax applies to 92.35% of net earnings, which accounts for the deductible employer-equivalent portion.5Office of the Law Revision Counsel. 26 USC 1402 – Definitions
On $100,000 of flipping profit, that’s roughly $14,130 in self-employment tax ($100,000 × 0.9235 × 0.153), not the $15,300 figure you’ll sometimes see. That bill sits on top of your regular income taxes, and it’s the main reason flippers eventually look at the S Corp election.
What the S Corp Election Actually Changes
An S Corp isn’t a separate entity. It’s a tax classification you elect for your existing LLC by filing Form 2553. The LLC stays an LLC for liability purposes; only the tax treatment changes.6Internal Revenue Service. S Corporations When an LLC timely files Form 2553, the IRS treats it as having elected corporate classification, so you don’t file Form 8832 separately.7Internal Revenue Service. Form 8832 – Entity Classification Election
Once the election is in place, you split what would have been self-employment income into two buckets. You pay yourself a W-2 salary subject to the full 15.3% in payroll taxes. Anything above that salary comes to you as a shareholder distribution and is not subject to Social Security or Medicare tax.8Internal Revenue Service. S Corporation Employees, Shareholders and Corporate Officers That’s where the savings come from.
Your LLC has to meet the S Corp eligibility rules to make the election: it must be a domestic entity, have no more than 100 shareholders (all individuals, certain trusts, or estates), and issue only one class of stock. Most single-member and husband-wife flipping LLCs qualify without any changes.6Internal Revenue Service. S Corporations
The Reasonable Salary Rule
You can’t game the split by paying yourself $10,000 and calling the rest a distribution. Courts have consistently held that S Corp shareholder-employees providing more than minor services must receive reasonable compensation, and disguising wages as distributions doesn’t survive audit.9Internal Revenue Service. Wage Compensation for S Corporation Officers The IRS looks at:
- Your training and experience
- The time and effort you actually put in
- What comparable businesses pay for similar work
- The duties and responsibilities you handle, from sourcing deals to managing subcontractors
For a full-time flipper running multiple projects, a defensible salary in many markets sits somewhere between $40,000 and $70,000, depending on experience and local pay scales. A CPA with real estate experience can help you land on a number you can defend.9Internal Revenue Service. Wage Compensation for S Corporation Officers
Running the Numbers on $100,000 in Profit
Say the business nets $100,000 for the year.
As a standard LLC, self-employment tax is roughly $14,130.4Internal Revenue Service. Self-Employment Tax (Social Security and Medicare Taxes)
As an S Corp paying yourself a $50,000 salary, combined employer and employee payroll tax on the salary runs $7,650 (15.3% × $50,000). The remaining $50,000 comes out as a distribution with no payroll tax attached. That’s about $6,480 less than the standard LLC would have paid.
The savings grow with profit, but not without limits. Social Security tax only applies to earnings up to $184,500 in 2026.10Social Security Administration. What Is the Current Maximum Amount of Taxable Earnings for Social Security Above that, only the 2.9% Medicare portion continues, so per-dollar savings shrink once your salary clears the cap.
The QBI Deduction Tradeoff
The qualified business income deduction lets pass-through owners deduct up to 20% of qualified business income. The One Big Beautiful Bill Act, signed in July 2025, made it permanent.11Office of the Law Revision Counsel. 26 US Code 199A – Qualified Business Income Both standard LLCs and S Corps qualify, but the S Corp election creates a wrinkle many flippers miss.
Your W-2 salary from the S Corp does not count as qualified business income. The statute specifically excludes reasonable compensation.11Office of the Law Revision Counsel. 26 US Code 199A – Qualified Business Income Only the K-1 profit above your salary qualifies. In a standard LLC, all your net income is potentially eligible.
This pulls against the payroll tax strategy. A higher salary cuts self-employment tax savings and also shrinks your QBI base. A lower salary boosts both, but raises audit risk if it’s not defensible. The optimal split depends on your total income, filing status, and whether you’re above the phase-out thresholds ($200,000 for single filers, $400,000 for married filing jointly in 2026). This is where a real estate CPA earns their fee.
The Added Costs of the S Corp Election
The election isn’t free. You need to run actual payroll, either through a service (typically $20 to $180 per month plus per-employee fees) or by handling quarterly tax deposits yourself. You’ll file Form 941 quarterly to report payroll taxes.12Internal 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 Schedule C. Most flippers hire an accountant for the 1120-S, adding $500 to $1,500 to what a basic Schedule C return costs.
Payroll service fees, extra accounting, and the time you’ll spend on compliance add up to roughly $2,000 to $4,000 per year in additional cost. At $30,000 in profit, S Corp payroll tax savings might only be $2,000 to $3,000, which the extra costs consume. Once profits reach $40,000 to $50,000 consistently, the math starts tilting toward the S Corp, and the advantage widens from there.
Same Liability Protection 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, business debts and lawsuits hit business assets first.
That protection only holds if you respect the line between yourself and the business. Courts can pierce the veil when the LLC is treated as an extension of the owner.13Legal Information Institute. Piercing the Corporate Veil The most common failure is commingling funds: paying personal expenses from the business account, depositing flip proceeds into a personal account, or letting the books drift. A dedicated business account and clean records go a long way.
When To Make the Switch
Think of this as a sequence, not a fork. Start as a standard LLC. Add the S Corp election when the numbers justify it. Rough benchmarks:
- Under $40,000 in annual profit: stay with the standard LLC. Compliance costs eat most of the S Corp savings.
- $40,000 to $75,000: run the numbers with a CPA. The election likely saves money after costs, but the margin depends on your reasonable salary and how QBI plays with your household income.
- Above $75,000: the election usually produces clear savings. At $150,000 in profit with a $60,000 salary, you could save $10,000 or more per year in payroll taxes after compliance costs.
Watch the Form 2553 deadline. It must be filed no more than two months and 15 days after the start of the tax year the election is to take effect, or any time during the preceding year.14Internal Revenue Service. Instructions for Form 2553 For a calendar-year business, that’s March 15. Realize in October that S Corp taxation would have saved you money this year, and you’re waiting until next year to make it happen. A CPA who works with real estate dealers can model the crossover for your income, filing status, and state tax situation before you file.
