You're launching a manufacturing business and need to choose a legal structure. Your lawyer mentions LLCs and corporations. Your accountant has opinions about S-corps and C-corps. Your business partner read something about pass-through taxation and double taxation. Everyone has advice, but you need a clear answer.
Which structure is right for your growing manufacturing startup: LLC or corporation?
The answer depends on your specific situation—funding plans, growth trajectory, tax position, and operational preferences. But understanding the fundamental differences helps you make an informed decision rather than just following generic advice.
Here's what manufacturing entrepreneurs need to know about choosing between LLC and corporate structures.
At the core, the distinction is about flexibility versus structure:
Limited Liability Company (LLC):
Corporation (C-Corp or S-Corp):
For manufacturers, the choice often comes down to growth plans and funding needs more than abstract legal preferences.
Both LLCs and corporations provide limited liability protection—your personal assets are protected from business debts and liabilities (assuming you maintain proper corporate formalities).
Whether you form an LLC or corporation, you get the same fundamental protection: creditors can't come after your house, car, or personal savings to satisfy business obligations.
Key requirement: Maintain separation between personal and business finances. Don't commingle funds, follow required formalities, and don't use the business as your personal piggy bank. These principles apply regardless of structure.
Understanding financial risk management planning helps protect your business beyond just entity structure.
Taxation creates the most significant practical differences between structures:
LLCs are "pass-through" entities by default. Business profits and losses flow through to owners' personal tax returns. The LLC itself doesn't pay federal income tax.
Single-member LLC: Treated as "disregarded entity"—report business income on Schedule C of your personal return.
Multi-member LLC: Treated as partnership—LLC files informational return (Form 1065), distributes K-1s to members showing their share of income/loss.
Advantage: Single layer of taxation. Profits taxed once at owner's personal rate.
Disadvantage: All profits subject to self-employment tax (15.3% on income up to $168,600 for 2024), even if you don't distribute cash.
Option: LLCs can elect S-Corp or C-Corp taxation, getting corporate tax treatment while maintaining LLC legal flexibility.
S-Corps are pass-through entities like LLCs but with important differences:
Tax advantage: Profits split between salary and distributions. Only salary subject to payroll taxes. Distributions avoid the 15.3% self-employment tax.
Example:
Restrictions:
Best for: Profitable businesses with $60,000+ in profit where payroll tax savings justify the additional complexity.
Understanding top line vs. bottom line helps evaluate whether S-Corp tax strategy makes sense for your profitability level.
C-Corps face "double taxation"—corporation pays tax on profits, shareholders pay tax on dividends.
Corporate tax rate: Flat 21% on all profits
Shareholder dividend tax: 0-20% depending on income (plus 3.8% net investment income tax for high earners)
Effective combined rate: Approximately 39.8% on distributed profits for high-income shareholders
Why anyone chooses C-Corp:
Retained earnings taxed once: If you reinvest profits rather than distributing, you pay only the 21% corporate rate. No personal tax until you take dividends.
Investor preference: Venture capital and institutional investors strongly prefer C-Corps. If you plan to raise significant capital, C-Corp is often required.
Employee equity: Stock options and equity compensation work more smoothly in C-Corps with established market valuations.
Going public: Only C-Corps can go public (IPO). If that's even a remote possibility, starting as C-Corp avoids conversion complexity.
If you plan to raise institutional investment—venture capital, private equity, or eventually go public—corporate structure (specifically C-Corp) is practically required.
Why investors prefer C-Corps:
Familiar structure: Well-understood governance, equity structures, and exit mechanisms.
Preferred stock: C-Corps can issue preferred stock with special rights—liquidation preferences, board seats, anti-dilution provisions—that protect investors.
Clean ownership: Shares are standardized and easily transferable. No complex operating agreements to navigate.
Exit options: Easier to sell, merge, or take public.
Tax considerations: Institutional investors (pension funds, endowments) have complex tax situations. C-Corp structure avoids certain tax complications for these investors.
LLCs and outside investment:
While possible to raise money as LLC, it creates complications:
For bootstrapped manufacturers: If you plan to fund growth through operating cash flow, debt financing, or friends and family investment, LLC flexibility may be preferable.
Understanding debt vs. equity financing options helps evaluate how entity structure affects funding strategy.
Corporations require more formalities and ongoing compliance:
Corporate requirements:
LLC requirements:
Reality check: Many small corporations get lax about formalities until they face litigation or due diligence. Then the lack of meeting minutes and proper documentation becomes a problem.
Best practice: Regardless of structure, maintain good corporate governance. Have regular meetings, document major decisions, keep clear records.
Working with a financial controller helps maintain proper financial records and compliance regardless of entity structure.
Benefits and equity compensation work differently across structures:
C-Corp owners: Can receive tax-free health insurance as employees.
S-Corp owners (>2% shareholders): Health insurance premiums are taxable compensation, though deductible.
LLC members: Health insurance treated as self-employed—deductible but not as flexible as corporate structures.
All structures can offer 401(k)s and other retirement plans. The mechanics differ slightly but practical impact is minimal for most small businesses.
C-Corps: Stock options (ISOs and NSOs) work cleanly with established valuation methodologies (409A valuations). Restricted stock awards are straightforward.
S-Corps: Can grant stock but valuation is trickier. ISOs don't work with S-Corps (must use NSOs).
LLCs: Profits interests or membership units can approximate equity compensation but are more complex and less familiar to employees.
For manufacturers hiring technical talent: If you plan to compete for employees with equity compensation, corporate structure (especially C-Corp) provides cleaner mechanisms.
You can convert from one structure to another, but it creates complexity:
LLC to C-Corp: Relatively straightforward. Often done when raising venture capital. May trigger tax if LLC has appreciated assets.
C-Corp to S-Corp: Possible but requires meeting S-Corp eligibility requirements. Built-in gains tax issues if assets have appreciated.
S-Corp to C-Corp: Simple conversion but loses pass-through taxation benefits.
Corporation to LLC: More complex, potentially triggering tax on asset transfers.
Starting strategy: Many advisors recommend starting simple (LLC) and converting to corporation if funding or complexity demands it. Others argue starting as you mean to continue (C-Corp if you plan aggressive growth) avoids conversion complexity.
State law governs entity formation with some key variations:
Delaware C-Corps: Many startups incorporate in Delaware for well-developed corporate law regardless of operating location.
Series LLCs: Some states allow Series LLCs—one LLC with separate "series" providing isolated liability. Useful for multiple product lines.
State taxes: Corporation vs. LLC tax treatment varies by state. California charges $800 minimum franchise tax on corporations.
Foreign registration: Operating in multiple states requires foreign entity registration where you do business.
Here's how to actually decide:
You're bootstrapping and don't plan to raise institutional capital soon
You want maximum flexibility in profit distributions and management structure
You prefer simplicity and minimal formalities
You have few owners (1-5) with aligned interests
Tax savings from S-Corp election don't justify additional complexity (profit <$60,000 or you want to distribute all profits anyway)
You operate multiple ventures and want liability separation (Series LLC)
Business is profitable ($60,000+ profit) and you want payroll tax savings
You plan to distribute most profits to owners rather than retain earnings
You meet eligibility requirements (<100 shareholders, U.S. citizens/residents only, one class of stock)
You want corporate structure but prefer pass-through taxation
You don't plan institutional fundraising in near future
You plan to raise venture capital or institutional investment
You want to retain significant earnings in the business (21% corporate rate vs. higher personal rates)
You plan aggressive growth potentially leading to acquisition or IPO
You'll offer significant equity compensation to employees
You have sophisticated investors who prefer corporate structure
International operations or ownership is planned (S-Corp restrictions don't work)
Understanding the importance of budgeting for maximizing profitability helps project profit levels that inform tax structure decisions.
Many small manufacturers choose an LLC but elect S-Corp taxation—getting operational flexibility with tax advantages:
How it works:
Best of both worlds for many small manufacturing businesses with $60,000-$500,000 in profit that aren't raising institutional capital.
Entity structure affects taxes, legal protection, fundraising, and operations. The right choice depends on your specific situation.
Work with both attorney and accountant: Attorneys focus on legal protection and governance. Accountants focus on tax implications. You need both perspectives.
Think about your 3-5 year plan: Where do you want the business to be? Raising capital? Selling? Growing through cash flow? Your trajectory matters more than current size.
Don't overthink the initial decision: You can change structures later if needed. Starting simple and converting when growth demands it is often smarter than starting with complexity you don't need yet.
Many manufacturers find that working with a fractional CFO helps evaluate tax implications and financial projections across different entity structures.
There's no universally "better" structure. LLC versus corporation depends on your specific circumstances:
Bootstrapped manufacturer with $100,000 profit and 2 owners? LLC electing S-Corp taxation likely optimal.
Manufacturing startup raising $2M venture capital? C-Corporation required.
Solo manufacturer-consultant with $60,000 income? Single-member LLC keeps things simple.
Growing manufacturer planning to scale to $10M+ revenue and hire technical talent with equity? Start as C-Corp.
The right structure balances tax efficiency, operational simplicity, fundraising needs, and long-term strategy. Don't choose based on what your neighbor did or what you read online. Evaluate your specific situation with professional guidance.
And remember: the entity structure matters less than building a great product, finding customers, and managing finances well. Get the structure right, but don't let the decision paralyze you from moving forward.
