For most profitable house flippers, the best tax structure for flipping houses is an LLC that elects to be taxed as an S corporation. The LLC gives you a liability shield around a business that involves contractors, construction defects, and six-figure projects. The S-Corp election then lets you split your profit into a reasonable salary and a distribution, and only the salary carries the 15.3% payroll tax bill. On a $200,000 profit, that split can save roughly $16,000 a year compared with operating as a sole proprietor or a plain LLC.
The right answer isn’t the same for everyone, though. Below is what each structure actually does to your tax bill, and where the S-Corp stops being worth the trouble.
Why Flipping Gets Taxed So Hard
The IRS treats houses you buy, renovate, and resell as inventory, not investment property. Profits are taxed as ordinary income at federal rates from 10% to 37%.1Internal Revenue Service.

On top of income tax, flipping is an active trade or business, so every dollar of net profit is hit with 15.3% self-employment tax: 12.4% Social Security plus 2.9% Medicare.2Internal Revenue Service. Self-Employment Tax (Social Security and Medicare Taxes) The Social Security portion applies to the first $184,500 in net self-employment earnings for 2026; the Medicare portion has no cap.3Social Security Administration. What Is the Current Maximum Amount of Taxable Earnings for Social Security Once your self-employment income clears $200,000 ($250,000 if married filing jointly), an additional 0.9% Medicare surtax applies to the excess.4Internal Revenue Service. Topic No. 560, Additional Medicare Tax
You can deduct half of the self-employment tax when calculating adjusted gross income, which shaves a little off your income tax.2Internal Revenue Service. Self-Employment Tax (Social Security and Medicare Taxes) The 15.3% itself is the real problem. Choosing an entity is mostly about reducing how much of your profit is exposed to it.
One boundary worth naming, because flippers ask about it constantly: you cannot use a 1031 like-kind exchange to roll flip profits into the next project. Section 1031 explicitly excludes property held primarily for sale, and that is exactly what a flip is.5Office of the Law Revision Counsel. 26 USC 1031 – Exchange of Real Property Held for Productive Use or Investment Every sale is fully taxable in the year it closes.
Sole Proprietor: The Default You Don’t Want
Start flipping without forming an entity and you are a sole proprietor by default. Two people splitting profits without a formal entity are a general partnership. Neither one requires a state filing, and that is about all they have going for them.
Income and expenses go on Schedule C of your Form 1040.6Internal Revenue Service. About Schedule C (Form 1040), Profit or Loss from Business (Sole Proprietorship) Every dollar of net profit is exposed to the full 15.3% self-employment tax. On $200,000 of net flipping income, that’s about $28,300 in self-employment tax alone, before income tax.
The liability side is just as ugly. There is no legal wall between you and the business. If a contractor gets hurt on your job site or a buyer sues over an undisclosed defect, your personal savings, your house, and your other assets are all on the table.
Standard LLC: Liability Fix, No Tax Fix
A limited liability company puts a legal wall between your personal assets and the business. Sue the LLC and creditors generally can’t reach your personal accounts, as long as you actually run it like a separate business. That is why the LLC is the popular choice among flippers.
You form one by filing articles of organization with your state’s business filing office.7Internal Revenue Service. Limited Liability Company (LLC) State filing fees generally run $50 to $225, and most states charge an annual report or franchise fee.
Here is the catch. A single-member LLC is a “disregarded entity” for federal tax purposes, so it files no separate return.8Internal Revenue Service. Single Member Limited Liability Companies Income still lands on your Schedule C and all of it is still subject to self-employment tax. A multi-member LLC defaults to partnership taxation, files Form 1065, and issues each active member a K-1 whose income is still fully hit by SE tax.9Internal Revenue Service. LLC Filing as a Corporation or Partnership
A plain LLC solves the liability problem. It does nothing about the tax problem. That’s where the S-Corp election comes in.
The S-Corp Election: Where the Savings Actually Come From
An LLC can elect S corporation tax treatment by filing IRS Form 2553.10Internal Revenue Service. Instructions for Form 2553 This is a federal tax classification, not a new entity. Your LLC stays an LLC under state law and keeps its liability shield; the IRS just taxes it as an S corporation.
After the election, you have to pay yourself a “reasonable salary” through payroll. That salary carries the standard 15.3% payroll tax, split between employer and employee sides. Any remaining profit passes through to you as a distribution, and distributions are not subject to self-employment or payroll tax. That gap is the whole point.
The math on $200,000 of net flipping profit looks like this:
- As a sole proprietor, self-employment tax applies to about 92.35% of net earnings, or roughly $28,300.
- As an S-Corp paying an $80,000 salary, payroll taxes on the salary run about $12,240. The remaining $120,000 comes through as a distribution with no payroll tax.
- Approximate savings: about $16,000 a year.
The savings grow with profit. A flipper netting $400,000 or more could save well over $20,000 annually. They shrink if your reasonable salary needs to be high relative to total profit, which is why this structure is a poor fit for someone netting $40,000 or $50,000.
Setting a Reasonable Salary
The IRS wants your salary to reflect what you would earn doing the same job for someone else. There are no fixed numbers in the code; the IRS evaluates each case on its facts.11Internal Revenue Service. Wage Compensation for S Corporation Officers The factors that matter are your training and experience, the time you actually spend on the business, what comparable roles pay in your market, and any compensation agreements in place.
Paying yourself too little is the fastest way to invite an audit. If the IRS reclassifies your distributions as wages, you owe back payroll taxes, interest, and penalties. A common approach is to research what a project manager or general contractor earns in your area and start there. It’s worth paying a CPA to document how you arrived at the number.
Eligibility
Not every business can be an S corporation. It must be a domestic entity, have no more than 100 shareholders, issue only one class of stock, and limit its owners to U.S. citizens or residents and certain trusts and estates.12Office of the Law Revision Counsel. 26 USC 1361 – S Corporation Defined A typical one- or two-owner flipping LLC has no trouble meeting these. Partnerships with foreign investors or complex ownership structures may not qualify.
A Small Bonus: Health Insurance
If you own more than 2% of the S corporation, premiums the company pays for your health coverage are reported as wages on your W-2 but exempt from Social Security and Medicare taxes.13Internal Revenue Service. S Corporation Compensation and Medical Insurance Issues You then take an above-the-line deduction for those premiums on your personal return. It’s a real perk if you buy your own coverage.
How the QBI Deduction Interacts With the Choice
Starting in 2026, the qualified business income deduction under Section 199A lets eligible owners deduct 23% of qualified business income from pass-through entities, up from 20%.14Congress.gov. Tax Provisions in H.R. 1, the One Big Beautiful Bill Act The One Big Beautiful Bill Act, signed in July 2025, made the deduction permanent.
Flipping qualifies as a Section 162 trade or business and doesn’t fall into the specified service categories (law, medicine, consulting, and the like).15Internal Revenue Service. Qualified Business Income Deduction You can claim QBI as a sole proprietor, a standard LLC, or an S-Corp. The wrinkle: with an S-Corp, your reasonable salary is not part of qualified business income, so only the distribution portion generates the deduction. In most cases, the self-employment tax savings from the election still dwarf the small QBI hit. High-income flippers should note that the deduction phases out above certain thresholds unless the business pays enough W-2 wages or holds enough depreciable property, and that calculation is worth running with a CPA.
Why a C Corporation Rarely Fits
A C corporation pays 21% corporate income tax on profits, and then you pay tax again on any dividends you take out. That double layer is a bad match for a business whose whole purpose is pulling cash out to fund the next project. An S-Corp gets you single-layer taxation and the salary-distribution split at the same time. The only C-Corp scenario worth considering is one where you plan to keep large amounts of profit inside the entity for years, which is unusual for flippers who constantly recycle capital.
Setting It Up in the Right Order
The setup sequence matters. Get it wrong and you can delay the S-Corp election or leave gaps in your liability protection.
File the LLC formation documents with your state first. Once the state confirms the entity exists, apply for an Employer Identification Number from the IRS. The IRS specifically tells you to form the entity before applying for an EIN, because doing it in the wrong order causes processing delays.16Internal Revenue Service. Get an Employer Identification Number The EIN application is free and takes minutes online.
To elect S-Corp taxation, file Form 2553 no later than two months and 15 days after the start of the tax year you want the election to cover, or any time during the preceding year.10Internal Revenue Service. Instructions for Form 2553 For a calendar-year LLC, that means March 15. Miss it and you either wait until next year or file a late election with a reasonable-cause explanation the IRS may or may not accept.
Once the election is in place, the S corporation files Form 1120-S by March 15 for calendar-year filers, a month ahead of the personal April 15 deadline.17Internal Revenue Service. Starting or Ending a Business The 1120-S produces the K-1 you need for your personal return, so a late corporate return cascades into a late personal one.
Finally, the liability shield isn’t automatic. Courts can pierce the veil if you treat the entity as an extension of yourself. The single most important rule is not mixing personal and business money: open a business bank account and run every project expense and every sale deposit through it. Keep an operating agreement, keep separate books, and pay your state’s annual report or franchise fee on time. Let the entity lapse and you can lose both the liability shield and the S-Corp election until you reinstate it.
