LLC vs S Corp: Differences, Taxes & How to Choose
Choosing between an LLC and S Corporation is one of the most important decisions you’ll make as a business owner. Both protect your personal assets, but they handle taxes, ownership, and operations very differently. Get this choice wrong, and you could pay thousands more in taxes or find yourself boxed into restrictions that hurt your business growth.
The short answer: If you’re a solo entrepreneur or small partnership earning less than $60,000 net profit, go with an LLC. If you’re running a profitable business with $80,000+ in net income, an S Corp election will likely save you money on self-employment taxes. If you plan to raise venture capital or have non-U.S. owners, stick with an LLC (or convert to a C Corporation later).

LLC Explained
An LLC (Limited Liability Company) is the most flexible business structure in the U.S. Think of it as a legal shield around your business that protects your personal assets while keeping everything else refreshingly simple.
How LLCs are taxed: By default, the IRS ignores your LLC for tax purposes. If you’re a single-member LLC, you report business income and expenses directly on your personal tax return using Schedule C. Multi-member LLCs file a partnership return (Form 1065), but the LLC itself pays no taxes. All profits “pass through” to the owners’ personal returns.
Here’s the catch: all LLC profits are subject to self-employment tax (15.3%) even if you leave the money in the business. On $80,000 in profit, that’s $12,240 in self-employment tax alone, before income taxes.
Real pros:
- Formation is straightforward and cheap ($50-$500 depending on your state)
- No ownership restrictions (corporations, LLCs, trusts, and foreign investors can all be members)
- Flexible profit splits (you can divide profits based on contribution, not just ownership percentage)
- No required meetings, corporate resolutions, or board of directors
- Easy to dissolve if things don’t work out
Real cons:
- Self-employment tax hits all profits, which gets expensive as you grow
- Some states impose annual franchise taxes (California charges $800 minimum)
- Banks and investors sometimes prefer corporations for lending or investment
- Can’t issue stock options to employees (you can do profit interests, but they’re more complex)
Best for: Freelancers, consultants, real estate investors, small partnerships, Amazon FBA sellers, and any business where you want maximum flexibility and expect profits under $60,000 annually.
S Corporation Explained
An S Corporation isn’t actually a business entity. It’s a tax election you make for your corporation (or LLC) that changes how the IRS treats your business income. Most people form a regular corporation, then immediately file Form 2553 to elect S Corp taxation.
How S Corps are taxed: This is where it gets interesting. S Corp profits split into two buckets: salary and distributions. You must pay yourself a “reasonable salary” for the work you do, which means payroll taxes (15.3%) on that salary. But additional profits can be distributed to you as a shareholder, and those distributions aren’t subject to self-employment tax.
Here’s a real example: your business nets $120,000. You pay yourself a $60,000 salary (subject to payroll taxes) and take $60,000 as distributions (not subject to self-employment tax). You just saved about $9,180 in taxes compared to an LLC.
Real pros:
- Significant self-employment tax savings on profits above your salary
- Clean structure for employees and contractors
- Easy to issue stock and stock options
- Investors and lenders understand corporations
- Built-in business credit separation
Real cons:
- Payroll complexity and costs (you need payroll software or service)
- Strict ownership rules: max 100 shareholders, all must be U.S. citizens or residents, only one class of stock
- Required corporate formalities (meetings, resolutions, separate business bank account)
- The “reasonable salary” requirement creates ongoing compliance risk
- More expensive to maintain ($1,000-$3,000 annually for payroll and tax prep)
Best for: Profitable service businesses, consultants replacing W-2 income, businesses with employees, and any company where the tax savings exceed the additional compliance costs.
The Tax Difference — This Is the Big One
Let’s walk through the real numbers because this is where your choice actually matters.
Scenario: You run a digital marketing consultancy that nets $100,000 after all business expenses.
As an LLC:
- Self-employment tax: $100,000 × 15.3% = $15,300
- Income tax: depends on your bracket, but let’s say 22% = $22,000
- Total tax burden: approximately $37,300
As an S Corp:
- Reasonable salary: $70,000 (payroll taxes: $70,000 × 15.3% = $10,710)
- Distribution: $30,000 (no self-employment tax)
- Income tax on total: $100,000 × 22% = $22,000
- Payroll processing: ~$1,200 annually
- Total tax burden: approximately $33,910
Your savings: $3,390 per year
The break-even point is usually around $60,000-$80,000 in net profit, depending on your reasonable salary level and state taxes.
When to talk to a CPA: If your net profit exceeds $60,000, if you’re unsure what constitutes “reasonable salary” in your industry, or if you have complex state tax situations. The IRS has successfully challenged S Corp owners who paid themselves unreasonably low salaries, resulting in penalties and back taxes.
Ownership, Management & Raising Money
LLC flexibility wins here. You can have silent partners who contribute capital but don’t work in the business. You can split profits 70/30 while ownership is 50/50. You can bring in an LLC or corporation as a member. Foreign investors are welcome.
S Corps are restrictive. Every owner must be a U.S. citizen or permanent resident. You can only have one class of stock, so everyone gets the same rights and profit distributions based on ownership percentage. Venture capital firms typically can’t invest in S Corps because they’re often structured as LLCs themselves.
For raising money: If you plan to bootstrap or take small angel investments from individuals, either structure works. If you want venture capital, you’ll likely need to be a C Corporation (you can start as an LLC and convert). If you plan to sell the business eventually, corporations are usually cleaner for buyers.
For issuing equity to employees: Corporations can issue stock options, which employees understand. LLCs can issue “profits interests,” but they’re more complex and less familiar to most people.
Which One Should You Pick?
Here’s our opinionated breakdown:
Choose LLC if you’re:
- A freelancer or solo consultant earning under $60,000 net profit
- Starting a partnership where you want flexible profit splits
- Planning to raise venture capital (start as LLC, convert to C-Corp later)
- A non-U.S. resident or want non-U.S. investors
- Running real estate investments (depreciation and loss pass-through benefits)
- Testing a business idea and want minimal compliance overhead
Choose S Corp if you’re:
- A profitable service business earning $80,000+ net profit
- Replacing W-2 income with consulting or freelancing at high income levels
- Running a business with employees where corporate structure makes sense
- Comfortable with payroll processing and corporate formalities
- Planning to stay domestic and keep ownership simple
The gray area ($60K-$80K net profit): This depends on your specific situation. Calculate the self-employment tax savings against the additional compliance costs. If you’re organized and don’t mind the formalities, S Corp probably makes sense at the higher end of this range.
Can You Switch Later?
Yes, and it happens all the time.
LLC to S Corp election: You can file Form 2553 to elect S Corp taxation for your LLC without changing your legal entity. This gives you the tax benefits while keeping LLC flexibility for ownership. It’s the most common conversion.
LLC to C Corporation: Popular when raising venture capital. You can convert your LLC to a corporation, though there may be tax implications depending on your basis and the LLC’s value.
S Corp to C Corp: Simple conversion, often done when you exceed S Corp ownership limits or want to raise institutional capital.
The timing: Most conversions happen at the beginning of a tax year to avoid mid-year complications. Plan ahead and consult a CPA for significant changes.
For International Founders
LLCs are generally better for non-U.S. residents. S Corps require all owners to be U.S. citizens or permanent residents, which eliminates most international founders immediately.
However, LLCs can create U.S. tax filing obligations for foreign owners, even if no U.S. taxes are owed. The “default” LLC tax treatment might not be optimal.
Common structure for international founders: Form an LLC, then elect C Corporation taxation. This avoids the S Corp citizenship requirements while providing corporate tax treatment. If you’re raising U.S. venture capital, this structure converts easily to a standard C Corp.
Tax treaties: If your home country has a tax treaty with the U.S., it might affect which entity type minimizes your overall tax burden. This gets complex quickly and varies by country.
Frequently Asked Questions
Can I have both an LLC and S Corp?
You can own multiple entities, but you can’t be both simultaneously. You can have an LLC that elects S Corp taxation, which combines the legal flexibility of an LLC with S Corp tax treatment.
How much does it cost to maintain each entity type?
LLCs typically cost $100-$800 annually (mostly state fees), plus tax preparation. S Corps add payroll processing ($1,000-$2,000) and more complex tax returns. Budget $2,000-$4,000 annually for S Corp compliance.
What if I don’t pay myself a salary in an S Corp?
The IRS can reclassify your distributions as salary, hitting you with back payroll taxes, penalties, and interest. “Reasonable salary” is based on what you’d pay someone else to do your job.
Do I need a lawyer to form an LLC or corporation?
For straightforward situations, no. Formation is mostly paperwork. You might want legal help for complex partnership agreements or if you’re raising money immediately.
Which entity type do investors prefer?
Angel investors usually don’t care. Venture capital firms strongly prefer C Corporations because of their own fund structures and exit requirements.
Can I deduct business expenses the same way with both entities?
Yes, business expense deductions are generally the same. The difference is how profits are taxed after expenses.
What happens if I choose wrong?
You can usually convert, but there might be tax consequences and costs. It’s better to choose correctly upfront, but a wrong choice isn’t permanent.
Do both entities protect my personal assets equally?
Yes, when properly maintained. Both LLCs and corporations create legal separation between your personal assets and business liabilities.
Making Your Decision
The LLC vs S Corp choice comes down to three main factors: your profit level, your need for flexibility, and your growth plans.
For most new businesses, an LLC provides the right balance of simplicity and protection. You can always elect S Corp taxation later when the numbers make sense. If you’re already profitable and replacing significant W-2 income, the S Corp tax savings probably justify the additional complexity.
Don’t overthink it. Both structures protect your personal assets, and you can change course as your business evolves. The perfect choice on paper doesn’t matter if it prevents you from actually starting your business.
