Double Taxation: What It Is & How to Avoid It

When you start a business, nobody explains that choosing the wrong entity type could mean paying taxes twice on the same money. But that’s exactly what happens with C-Corporations, and it’s called double taxation.

Here’s the short answer: If you’re starting a small business and want to avoid double taxation, form an LLC or S-Corporation. If you plan to raise venture capital or go public someday, a C-Corporation makes sense despite the tax hit.

Quick Comparison: C-Corp vs. LLC vs. S-Corp

What Is Double Taxation?

Double taxation means the IRS taxes your business profits twice: once at the corporate level, then again when you take money out as dividends.

Here’s how it works. Your C-Corporation makes $100,000 profit. The company pays corporate income tax (21% federally) on that $100,000. Then, when you distribute the remaining $79,000 to yourself as dividends, you pay personal income tax on it again.

So you’re paying tax twice on the same $100,000.

This doesn’t happen with LLCs or S-Corporations because they have “pass-through taxation.” The business doesn’t pay corporate tax. Instead, profits and losses pass through to your personal tax return.

C-Corporation Tax Structure

A C-Corporation is a separate tax entity. It files its own tax return (Form 1120) and pays corporate income tax on profits.

The federal corporate tax rate is 21%. Most states add another 3-8% in corporate income tax. So your company might pay 24-29% total corporate tax.

Then, when you take money out as dividends, you pay personal tax on those dividends. The dividend tax rate is 0%, 15%, or 20% depending on your income level.

Real example: Your C-Corp makes $100,000 profit in California.

Corporate tax (21% federal + 8.84% CA): $29,840
Remaining profit: $70,160
You take $50,000 in dividends
Personal tax on dividends (15%): $7,500
Total tax paid: $37,340 on $100,000 profit

C-Corporation pros:

No limit on number of shareholders
Can issue different classes of stock
Investors and VCs prefer C-Corps
No self-employment tax on profits
Can retain earnings in the business at 21% tax rate

C-Corporation cons:

Double taxation on distributions
More paperwork and compliance requirements
Must hold annual meetings and keep corporate minutes
Can’t deduct business losses on personal returns

Best for: Businesses raising venture capital, planning to go public, or keeping most profits in the business for growth.

LLC Tax Structure

An LLC doesn’t pay corporate income tax. All profits and losses pass through to the owners’ personal tax returns.

If you’re the only owner, you report LLC income on Schedule C of your personal return. With multiple owners, the LLC files Form 1065 and issues K-1s showing each owner’s share of profits and losses.

The self-employment tax issue: LLC profits are subject to self-employment tax (15.3% for Social Security and Medicare). This applies to your entire share of LLC profits, even money you leave in the business.

Real example: Your LLC makes $100,000 profit.

Self-employment tax: $15,300
Income tax (assume 22% bracket): $22,000
Total tax: $37,300

LLC pros:

Simple formation and maintenance
Complete flexibility in profit/loss sharing
Can deduct business losses against other income
No double taxation
Fewer compliance requirements

LLC cons:

Self-employment tax on all profits
Less attractive to investors
Can’t easily issue equity to employees
Some states charge high LLC fees (California charges $800+ annually)

Best for: Small businesses, real estate investors, freelancers, and consultants earning under $60,000 annually.

S-Corporation Tax Structure

An S-Corporation combines the best parts of LLCs and C-Corps for many small businesses. It has pass-through taxation like an LLC, but owners who work in the business must take a “reasonable salary.”

The magic happens because you only pay self-employment tax on your salary, not on additional profits you take as distributions.

Real example: Your S-Corp makes $100,000 profit. You take a $60,000 salary.

Payroll taxes on salary: $9,180 (split with company)
Income tax on $100,000: $22,000
Total tax: $31,180

That’s $6,120 less than the LLC example above.

S-Corporation pros:

No double taxation
Self-employment tax savings on profits above salary
Can still deduct losses on personal returns
More credible than LLC for some businesses

S-Corporation cons:

Must pay yourself a reasonable salary
Limited to 100 shareholders
Only one class of stock
More payroll compliance than LLC
Investors generally don’t like S-Corps

Best for: Profitable service businesses, consultancies, and small companies where owners work in the business and net over $60,000 annually.

The Tax Difference — Real Numbers

Let’s compare the same $150,000 profit across all three entity types:

LLC:

Self-employment tax: $21,180
Income tax (24% bracket): $36,000
Total: $57,180

S-Corporation (taking $80,000 salary):

Payroll taxes: $12,240
Income tax: $36,000
Total: $48,240
Savings vs. LLC: $8,940

C-Corporation (taking $80,000 salary + $55,300 dividends):

Corporate tax on remaining $70,000: $14,700
Payroll taxes on salary: $12,240
Income tax on salary: $19,200
Tax on dividends: $8,295
Total: $54,435

The S-Corp wins in this scenario, but only because we’re taking money out. If you wanted to keep $50,000 in the business for growth, the C-Corp would save money because retained earnings are only taxed once at 21%.

When to talk to a CPA:

Your business nets over $60,000 annually
You’re considering keeping significant profits in the business
You have business partners with different income levels
You’re planning to raise investment capital
Your entity choice affects your personal tax situation significantly

Ownership, Management & Raising Money

C-Corporations are built for growth and investment. You can have unlimited shareholders, issue preferred stock, and create employee stock option plans. VCs and angel investors almost always require C-Corp structure because it’s familiar and flexible.

LLCs offer complete flexibility in splitting profits and ownership, but they’re terrible for raising money. Most investors won’t invest in LLCs because of tax complications.

S-Corporations fall in the middle. You can have up to 100 shareholders and issue stock to employees, but you can’t have different classes of stock or foreign investors.

If you ever want to sell your business, C-Corps often get higher valuations because they’re easier for buyers to understand and finance.

Which One Should You Pick?

Here’s our opinionated decision framework:

Choose an LLC if you’re:

A freelancer or consultant earning under $60K annually
In real estate investment (depreciation benefits)
Want maximum flexibility with minimal paperwork
Not planning to raise outside investment
In a state with no LLC fees (most states)

Choose an S-Corporation if you’re:

Running a profitable service business (law firm, consultancy, agency)
Earning $60K+ net profit annually
Working in the business (not just investing)
Want payroll tax savings but don’t need outside investment
Comfortable with moderate compliance requirements

Choose a C-Corporation if you’re:

Planning to raise venture capital or angel investment
Want to go public someday
Building a tech startup or high-growth business
Comfortable keeping profits in the business for several years
Need to issue stock options to employees

For e-commerce and online businesses: Start with an LLC for simplicity. Convert to S-Corp when you’re consistently profitable and netting over $60,000. Convert to C-Corp when you’re ready to raise institutional investment.

Can You Switch Later?

Yes, and it’s common. Most successful businesses change entity types as they grow.

LLC to S-Corporation: Easy. File Form 2553 with the IRS by March 15th of the year you want the election to start. No state filing required in most states.

LLC to C-Corporation: More complex. You’ll need to file articles of incorporation in your state and may trigger tax consequences if your LLC has appreciated assets.

S-Corp to C-Corp: Simple. Just revoke your S-election or let it expire when you exceed S-Corp limits (like taking on too many shareholders).

The key is timing these conversions for tax efficiency. Work with a CPA before making any switches.

For International Founders

If you’re not a U.S. citizen or resident, entity choice gets more complicated.

C-Corporations are generally better for international founders because:

No pass-through income to complicate your home country taxes
Tax treaties often provide better rates on dividends
Easier to get U.S. business bank accounts and credit
Required structure for most U.S. investors

LLCs can create tax nightmares for international owners because many countries don’t recognize LLC pass-through taxation. You might face double taxation anyway.

S-Corporations don’t allow foreign ownership, so they’re not an option for non-residents.

Most international founders should start with a C-Corporation and Delaware incorporation for maximum flexibility.

Frequently Asked Questions

Can I avoid double taxation by not taking dividends?
Yes, but only temporarily. If you keep profits in the business, you only pay the 21% corporate rate. But you’ll eventually pay personal tax when you take money out or sell the company.

What about the Section 199A deduction for pass-through entities?
This deduction can reduce your taxable income from LLCs and S-Corps by up to 20%, but it phases out at higher income levels and doesn’t apply to many service businesses. It’s complex enough that you should discuss it with a CPA.

Do I really need to pay myself a “reasonable salary” in an S-Corp?
Yes. The IRS audits S-Corps that pay tiny salaries to avoid payroll taxes. “Reasonable” means what you’d pay someone else to do your job. Expect 50-60% of profits as a starting point.

Can I elect S-Corp tax treatment for my LLC?
Yes, by filing Form 8832. This gives you S-Corp tax benefits while keeping LLC legal flexibility. It’s popular but adds complexity.

What if I’m in a state with no income tax?
You still pay federal taxes, so the analysis doesn’t change much. C-Corps still face double taxation, and S-Corps still save on self-employment taxes.

How much does entity type really matter for a small business?
For businesses netting under $40,000, the differences are small enough that simplicity (LLC) usually wins. Above $60,000, the tax differences become significant enough to justify additional complexity.

Making Your Decision

Double taxation sounds scary, but it’s just one factor in choosing your business entity. C-Corporations make sense when you need investment or plan to keep profits in the business. For most small businesses, LLCs offer simplicity while S-Corporations provide tax savings once you’re profitable.

The biggest mistake is overthinking it early on. Start simple with an LLC, focus on building a profitable business, then optimize your structure as you grow.
