You’re wondering which business structure makes sense for your real estate investments or active business. The names sound complex, but the choice really comes down to three questions: Do you need liability protection? Is your business active or passive? And does the tax math actually work? I’ll walk you through each structure in plain language and show you exactly when each one saves money.
LLC: Liability Protection, Not a Tax Cut
An LLC (limited liability company) is primarily a liability shield. It separates your personal assets from your business obligations. If someone slips and falls at one of your properties, they typically sue the LLC, not you personally.
The tax mistake most people make is assuming an LLC automatically saves them money. It doesn’t. An LLC is a legal structure for protection; it is not itself a tax classification. By default, a single-member LLC is taxed as a sole proprietorship, and a multi-member LLC is taxed as a partnership. The income flows through to your personal return the same way.
For rental properties, this matters: income inside an LLC is generally passive and not subject to the 15.3% self-employment tax. That is already a win compared to a sole prop business. But here is the key takeaway: if you are holding rental property in an LLC and doing nothing else, you get the liability shield but not a special tax deduction just for having the LLC.
Key takeaway: An LLC gives you legal protection and structures your liability, but the tax classification that actually drives your return is what matters.
S-Corporation: When the Math Works
An S-corp (S-corporation) is worth analyzing once an active business generates roughly $50,000 or more in profit. This is where the self-employment tax savings kick in.
Here is how it works. If you own an active business and operate it as a sole proprietorship or partnership, you pay the full 15.3% self-employment tax on your profit. On $100,000 of active profit, that is roughly $15,300 in self-employment tax hitting your return.
With an S-corp, you must pay yourself a W-2 salary. That salary is subject to ordinary payroll taxes (7.65% employee side plus employer side matching). But the remaining profit can be taken as distributions, and distributions avoid the 15.3% self-employment tax entirely.
Let’s use real math. Suppose your active business nets $100,000 in profit. As an S-corp, you pay yourself a reasonable $50,000 salary (payroll tax applies to that), and the remaining $50,000 comes out as distributions with no self-employment tax. Instead of paying 15.3% on $100,000 (roughly $15,300), you pay payroll tax only on the salary. The result: meaningful self-employment tax savings, often running into thousands per year at this profit level.
But here is what kills the S-corp benefit: the word “reasonable.” The IRS requires reasonable compensation. There is no valid $1 salary strategy. You must document what you actually earned: your role, your hours worked, your duties, and your industry’s pay data. If you get audited and your $50,000 salary looks low for the work you do, the IRS can reclassify distributions as wages, hit you with back payroll taxes, and add penalties.
The S election is also a multi-year commitment. You cannot flip in and out of it year to year depending on profit. Plan on it being your structure for at least three to five years, and be prepared to document reasonable comp annually.
Key takeaway: S-corp saves self-employment tax on active business profit above roughly $50,000, but only if you document reasonable salary and stick with it.
C-Corporation: Rare for Rental Investors
A C-corp (C-corporation) is taxed at a flat 21% corporate rate. It is a separate entity from you, meaning it pays tax on its profit, and then when you take money out as dividends, you pay tax again. That double taxation is the risk.
For a few specific situations, a C-corp can make sense: high-profit businesses where you plan to retain earnings, or specific income-deferral strategies. But for most rental property investors, it creates problems that outweigh any benefit.
Key takeaway: C-corp flat taxation can be attractive in narrow cases, but the double tax risk usually makes it a poor fit.
Why Rental Property Should Stay Out of Corporations
This is critical. If you own rental property and put it inside an S-corp or C-corp, you inherit several tax problems.
First, you lose the step-up in basis. When you die, your heirs normally inherit property at fair market value as of the date of your death. This can erase decades of appreciation and save them significant capital gains tax. But if the property sits inside an S or C corp at your death, the step-up does not apply cleanly. Your heirs inherit the corporation’s low cost basis, not the stepped-up value.
Second, if you ever try to remove the property from the corporation, you trigger a taxable sale at the property’s fair market value. That is an immediate capital gains tax you did not anticipate.
Third, depreciation recapture on the property still applies when you sell. For individuals, unrecaptured Section 1250 gain on the building is taxed at a maximum of 25% (and any Section 1245 recapture on cost-segregated components at ordinary rates), but inside a corporation the entire gain is taxed at the corporation’s rates, and the corporate structure complicates the calculation.
Fourth, estate planning gets messy. You now have to deal with corporate governance, K-1s, and liquidation complexities that add cost and time.
The simple rule: keep your rental property in an LLC for liability protection, or hold it in your personal name. Never put it in an S or C corp.
Key takeaway: Rental property in a corporation creates step-up, recapture, and estate planning headaches that are not worth it.
Decision Drivers: How to Choose Your Structure
Choosing the right entity is not one-size-fits-all. Here are the factors to weigh.
Active versus passive income. If you are a W-2 earner who owns rentals on the side, an LLC works fine for the rentals because rental income is passive. If you have an active business on top of your rentals, the S-corp conversation matters for the active piece. Never for the rentals.
Income level. Below $50,000 in active business profit, an S-corp usually does not pay for itself. The annual compliance costs and complexity outweigh the self-employment tax savings. Above $50,000, run the math.
QBI deduction impact. The qualified business income deduction (up to 20% of certain business income) interacts with your entity choice. This is worth reviewing with a professional.
Retirement plan goals. An S-corp can sponsor a Solo 401(k) based on W-2 wages, not business profit. For some high-income earners, this is a powerful tool. A sole prop or partnership can sponsor a SEP-IRA.
Liability needs. If you have significant liability exposure, an LLC or corporation protects personal assets. If you are a rental-only investor with good insurance, the liability benefit is smaller.
Long-term plans. Are you planning to exit, transition to an heir, or hold for decades? Estate planning and sale tax consequences change the picture.
Key takeaway: The right entity depends on your specific situation. Get a real entity analysis, not a rule of thumb.
Frequently Asked Questions
Should I be an LLC, S-corp, C-corp, or sole proprietor?
It depends on three things: whether you need liability protection, whether your income is active or passive, and whether the numbers justify the compliance cost. Rental property investors usually start with an LLC for protection. Active business owners above $50,000 profit should analyze S-corp. C-corp is rare for real estate. A professional entity analysis is worth the cost.
When should I become an S-corp?
Run the analysis once your active business nets roughly $50,000 or more. Factor in the annual compliance costs (usually $500 to $1,500 per year), reasonable W-2 salary requirements, and the multi-year commitment. If the self-employment tax savings exceed the costs, you have a case.
Is paying myself a $1 salary in an S-corp a tax mistake?
Yes. The IRS requires reasonable W-2 compensation for work actually performed. A $1 salary will not survive an audit if your job duties and industry pay data suggest otherwise. Document your actual role and hours, and pay yourself in line with what someone else would earn doing the same work.
Should I put my rental properties in an S-corp or C-corp?
No. Rental property in a corporation costs you the step-up in basis at death, triggers a tax hit if you remove it, adds recapture complications, and creates estate planning headaches. Keep rentals in an LLC or personal ownership.
Does an LLC save me taxes, or just protect me legally?
Just protect. An LLC is a liability shield. The tax treatment depends on your entity classification (sole prop, partnership, S-corp, or C-corp). For rental property, an LLC does offer a passive income advantage: no self-employment tax. But the LLC itself is not a tax strategy; it is a legal one.
