For most small businesses, an LLC is the simpler and cheaper choice, while a corporation (especially a C corporation) makes more sense when you plan to raise venture capital, issue stock options, or eventually go public.
Both protect your personal assets from business debts, so the real differences come down to taxes, paperwork, ownership flexibility, and where you want the company to go.
The decision is not permanent, either. Many owners start as an LLC and later elect corporate tax treatment or convert as the business grows.
This guide walks through the practical differences, the 2026 tax and compliance changes that matter, and a simple way to decide.
It is general information, not legal or tax advice, so run your final choice past a CPA or attorney who knows your state.
What Changed in 2026 That Affects This Decision
Three recent developments are worth knowing before you compare structures:
- The 21% federal corporate tax rate is permanent. C corporations pay a flat 21% on taxable income, and that rate is not scheduled to expire.
- The 20% QBI deduction is now permanent too. The One Big Beautiful Bill Act, signed July 4, 2025, made the Section 199A qualified business income deduction permanent, according to Millan CPA's 2026 summary.
- It lets eligible pass-through owners (LLCs taxed as sole proprietors or partnerships, and S corporations) deduct up to 20% of qualified business income, and C corporations do not get it.
- Older articles that say the deduction expires in 2025 or 2026 are out of date.
- Federal beneficial ownership reporting is gone for U.S. companies. FinCEN's final rule, effective August 14, 2026, permanently exempts U.S. domestic companies from reporting beneficial ownership information under the Corporate Transparency Act, per law firm Troutman Pepper Locke.
- The federal rule does not preempt state-level reporting rules, so check your state.
LLC vs Corporation: Quick Comparison
| Feature | LLC | C corporation | S corporation |
|---|---|---|---|
| What it is | Legal entity that separates owners from the business | Separate legal entity owned by shareholders | A tax election for an eligible corporation or LLC |
| Personal liability | Owners generally not personally liable | Shareholders generally not personally liable | Shareholders generally not personally liable |
| Default taxation | Pass-through (owners report profits on personal returns) | Taxed at the corporate level, then dividends are taxed again | Pass-through |
| Federal tax rate | Owners' individual rates, minus the QBI deduction if eligible | Flat 21% | Owners' individual rates, minus the QBI deduction if eligible |
| Ownership rules | Flexible, with few restrictions | Unlimited shareholders and multiple stock classes | Up to 100 shareholders, one class of stock, eligible shareholders only |
| Formalities | Light | Bylaws, board, annual meetings | Same as a corporation |
| Best for | Most small businesses and solo owners | Startups seeking investors, and companies planning an IPO | Profitable owner-operators who qualify |
The SBA's business structure guide notes that designations like S corp are not strictly separate structures but tax statuses, and that an LLC can be taxed as a C corporation or an S corporation.
What Is an LLC?
A limited liability company is a state-registered business entity that blends features of a corporation and a partnership.
The SBA says being an LLC protects your personal assets and separates them from business assets.
By default, a single-owner LLC is taxed as a sole proprietorship and a multi-owner LLC is taxed as a partnership, which means the LLC itself does not pay federal income tax.
Profits flow to the owners, who pay income tax and self-employment tax on their share.
If you want a longer walkthrough of how an LLC stacks up against sole proprietorships, partnerships, and corporations, see this explainer on LLC vs. other business structures.
Why owners like it: simple setup, minimal ongoing paperwork, flexible management, and tax choices you can change later.
Watch out for: self-employment tax on all profits by default, and some investors who prefer to fund corporations.
What Is a Corporation?
A corporation is a legal entity separate from its owners, with shares of stock, a board of directors, and officers.
There are two main tax types:
- C corporation: The default. It pays corporate income tax at 21%, and shareholders pay tax again when profits are paid out as dividends. This is often called double taxation.
- S corporation: Not a separate entity type, but a tax election made by filing IRS Form 2553.
- To qualify, a company generally needs no more than 100 shareholders, only eligible shareholders (not partnerships, corporations, or nonresident aliens), and one class of stock. Owner-employees must be paid a reasonable salary.
The SBA also notes that some states tax S corporations on profits above a set limit, and others do not recognize the S election at all.
8 Key Differences Between an LLC and a Corporation
1. Formation and Paperwork
An LLC needs articles of organization filed with your state and, in most cases, an operating agreement.
A corporation files articles of incorporation, adopts bylaws, appoints directors, and issues stock. Corporations generally face more required paperwork, while LLCs keep things lighter.
2. Personal Liability Protection
Both structures generally shield your personal assets from business debts and lawsuits.
Neither protects you from your own wrongdoing, personal guarantees on loans and leases, or unpaid payroll taxes in some situations.
Protection can also weaken if you mix personal and business money, so keep separate bank accounts and records.
3. Taxes
This is the biggest difference for most owners.
- LLC (default): Profit passes through to your personal return. You owe income tax plus self-employment tax (Social Security and Medicare), and you may qualify for the 20% QBI deduction.
- C corporation: The company pays 21% federal tax on profit. If it pays dividends, shareholders pay tax again.
- S corporation: Profit passes through, but owners can split income between a reasonable salary (subject to payroll taxes) and distributions (not subject to self-employment tax).
- Reasonable salary rules are strict, so the IRS expects the pay to match what you would pay someone else to do the work.
A simple illustration: if a C corporation earns $100,000, it pays $21,000 in federal tax and keeps $79,000.
If it pays out the rest, shareholders owe tax on those dividends. A pass-through owner pays tax once at personal rates on that $100,000, possibly reduced by the QBI deduction.
Which comes out ahead depends on your tax bracket, how much profit you leave in the business, and your state taxes.
4. Ownership and Investors
LLCs can have one member or many, and they can include individuals, other businesses, or foreign owners.
Investors in venture-backed startups, however, usually prefer C corporations because of standard stock structures and option plans.
S corporations restrict who can own shares and allow just one class of stock.
5. Management Structure
LLCs can be run by their owners (member-managed) or by appointed managers. Corporations follow a formal chain: shareholders elect a board, the board appoints officers, and officers run the company.
6. Ongoing Compliance
LLCs typically file an annual or biennial report and pay state fees. Corporations have the same state filings plus meeting minutes and board records.
States also differ on annual franchise or minimum taxes, and a few charge LLCs and corporations similar annual amounts, so check your state's rules.
7. Raising Money and Equity
Corporations can issue shares and stock options, which makes them easier to scale through outside funding.
LLCs can bring in investors too, but they do it through membership interests and custom operating agreements, which can get complicated.
8. Flexibility and Exit
LLCs can change their tax classification later, for instance by electing S corporation status. Selling or exiting also differs:
A corporation's stock is simple to transfer, while an LLC's membership interests depend on the operating agreement. If you might sell the business or take it public, talk to an advisor early.
When an LLC Is the Better Choice
An LLC usually fits if you:
- Are a solo owner, freelancer, or small team without outside investors.
- Want liability protection without heavy formalities.
- Prefer pass-through taxes and may qualify for the QBI deduction.
- Own real estate or a small service business.
- Want flexibility to adjust your tax treatment later.
When a Corporation Is the Better Choice
A corporation often wins if you:
- Plan to raise venture capital or angel funding.
- I want to issue stock options to employees.
- Expect to go public or be acquired.
- Plan to keep most profits in the business, where the 21% corporate rate may beat higher personal rates.
- Need a clear governance structure with a board.
When Does an S Corporation Election Make Sense?
An S election can help profitable owner-operators lower self-employment taxes, because only the reasonable salary is subject to payroll tax, while the rest can be taken as distributions.
It adds costs and rules, including payroll, a separate tax return (Form 1120-S), and reasonable compensation requirements.
Tax advisors generally recommend modeling the numbers with a CPA before you elect, since savings depend on your profit level, your state, and what a fair salary would be.
How to Form an LLC or Corporation
The steps are similar for both:
- Choose a state. Most owners form where they live and do business, since you may need to register as a foreign entity in other states.
- Pick a name and check that it is available.
- Appoint a registered agent with a physical address in the state.
- File formation documents (articles of organization or incorporation) and pay the state fee.
- Create internal documents: an operating agreement for an LLC, or bylaws for a corporation.
- Get an EIN from the IRS.
- Open a business bank account and keep finances separate.
- Get licenses and permits, and set up state and local tax accounts.
- Consider an S election if it fits, with the filing deadline in mind.
Do You Need a Formation Service?
You can file directly with your state for the filing fee, or pay a service to handle the paperwork.
Services like Bizee (formerly Incfile) and LegalZoom market low-cost entry packages, with the state filing fee extra.
According to 2026 comparison sites, Bizee's base package costs $0 plus state fees and includes a year of registered agent service, while LegalZoom's registered agent service is priced separately at about $249 a year.
Pricing and package contents change, so verify before you buy. For a side-by-side, see this Bizee vs LegalZoom comparison, and weigh what you actually need, since you may not need extras like trademark or website add-ons.
Registered Agents, Renewals, and Support
A registered agent receives legal papers and official notices for your company, and most states require one.
Free first-year offers are common, and 2026 reviews say Bizee's registered agent service renews at about $119 a year after the free period, which some customers cite as a surprise.
If you are choosing a service, read about what support looks like before you commit.
This overview of Bizee customer service covers what to expect from the company's help channels, and you should also check reviews from the past year, since service quality changes.
Costs to Budget For
| Cost | LLC | Corporation |
|---|---|---|
| State formation filing fee | Varies widely by state | Varies widely by state |
| Registered agent | Free first year with some services, then paid | Same |
| Annual report or franchise tax | Varies by state | Varies by state |
| Accounting and tax filing | Usually simpler | Usually higher, with a separate corporate return |
| Legal help | Optional but helpful for operating agreements | More often needed for bylaws and stock |
| Payroll setup | Needed if you hire, or elect S status | Required for officers who are paid |
Which Structure Should You Choose?
| If this describes you | Likely fit |
|---|---|
| Solo freelancer or consultant | LLC |
| Small local business, no outside investors | LLC |
| Profitable owner-operator with steady income | LLC with an S election |
| Startup planning to raise venture funding | C corporation |
| Business planning to reinvest most profits | C corporation, worth modeling |
| Real estate holding company | LLC |
| Multiple founders wanting flexible profit sharing | LLC with a strong operating agreement |
Common Mistakes to Avoid
- Picking a structure based on one tax rate. Consider your whole picture: salary, state taxes, growth plans, and exit.
- Mixing personal and business money, which can weaken liability protection.
- Skipping the operating agreement or bylaws. Written rules prevent disputes.
- Missing the S election deadline. Form 2553 has strict timing, though the IRS offers late-election relief in some cases.
- Underpaying yourself in an S corporation. The IRS expects a reasonable salary.
- Ignoring state rules. Some states do not recognize S status or charge annual minimum taxes.
- Assuming the choice is permanent. You can often change structures as the business evolves, though conversions can have tax consequences.
Frequently Asked Questions
Is an LLC or a corporation better for a small business?
For most small businesses, an LLC is the simpler, cheaper starting point. A corporation is usually better if you want outside investors or stock options.
Does an LLC have to pay corporate tax?
Not by default. A single-member LLC is taxed like a sole proprietorship and a multi-member LLC like a partnership. An LLC can elect to be taxed as a corporation if that makes sense.
Can an LLC elect S corporation status?
Yes. An eligible LLC can elect S corporation tax treatment by filing Form 2553, as long as it meets the requirements.
What is double taxation?
It is when a C corporation pays corporate income tax on profits and shareholders pay tax again on dividends. Pass-through entities avoid the corporate layer.
Do I still need to file beneficial ownership reports in 2026?
Under FinCEN's final rule effective August 14, 2026, U.S.-formed companies are exempt from federal BOI reporting. Foreign companies registered to do business in the U.S. and some state-level rules may still apply.
Can I switch from an LLC to a corporation later?
Yes, many businesses do. A conversion or tax election can have legal and tax effects, so plan it with a professional.
Final Thoughts
If you are unsure, start with the structure that matches today's reality and leave room to change.
A solo or small business with no investors is usually well served by an LLC, possibly with an S election as profits grow.
A startup headed for outside funding should talk to a lawyer about forming a C corporation early.
Whichever you choose, keep business and personal money separate, write down your ownership rules, and review the structure every year or two with a CPA.
