LLC vs. Corporation: What's Better for a Growing Manufacturer?

The short answer: I think for most growing manufacturers, an LLC or S corporation taxed as a pass-through is the better fit, and a C corporation makes sense in a narrower set of cases. A startup that plans to raise venture money usually picks a C corporation because that's what VC funds want. An established manufacturer with steady profits, bank debt and an eventual sale in mind is a different case.

This post walks through how the choice plays out for a manufacturer doing $3 million to $30 million in sales. It uses the rules in effect for 2026 after the 2025 tax law, often called the One Big Beautiful Bill Act.

This is general information, not tax or legal advice. Entity choice depends on your facts, your state and your plans, so work with your CPA and attorney. We coordinate with them on the numbers.

What are the basic differences between an LLC and a corporation?

There are two separate questions here, and people often mix them up. One is the legal entity under state law. The other is how the IRS taxes it.

An LLC is a state-law entity. For tax, it can be treated as a sole proprietorship (one owner), a partnership (two or more owners), an S corporation or a C corporation. A corporation is taxed as a C corporation by default and can elect S corporation status if it qualifies.

Setup	Who pays income tax	Typical fit
LLC taxed as partnership	Owners, on their share of profit	Multiple owners, flexible splits, real estate held separately
LLC or corporation taxed as S corp	Owners, on their share of profit	Owner-operators who take a salary plus distributions
C corporation	The company at 21%, then owners on dividends	Retaining most profit in the business, certain sale plans, QSBS

Is liability protection different?

Not much. LLCs and corporations both protect owners from the company's debts, as long as you keep the company separate. That means a separate bank account, real records and no mixing of personal and business money.

In practice, your bank will usually ask for a personal guarantee on the line of credit and equipment loans either way. So the entity choice rarely changes what you personally owe the bank. Insurance and good contracts matter more for product liability than the entity type.

How is each structure taxed in 2026?

C corporation

A C corporation pays a flat 21% federal tax on its taxable income. If it pays dividends, owners pay tax again, generally up to 20% on qualified dividends plus the 3.8% net investment income tax. That's the "double tax."

The double tax only bites when profit leaves the company. If you reinvest most of your profit in equipment and inventory, the 21% rate on retained earnings can look attractive.

LLC taxed as a partnership

The LLC pays no federal income tax. Profit flows to the owners on a K-1, and they pay at their own rates, whether or not cash is distributed. Active owners generally pay self-employment tax on their share of operating profit as well.

S corporation

An S corp also passes profit through to owners. Owners who work in the business must take a reasonable salary, which carries payroll tax. The rest comes out as distributions, which don't carry payroll tax. For an owner-operator, that's often the main reason to pick S status over a plain LLC.

The QBI deduction

Owners of pass-through businesses can deduct up to 20% of qualified business income under Section 199A. The 2025 law made this deduction permanent. For 2026, the wage and property limits start to apply above taxable income of $201,750, or $403,500 for married couples filing jointly.

Above those levels, the deduction is limited by W-2 wages paid and the cost basis of equipment and other qualified property. Manufacturers usually have payroll and equipment, so many keep a large part of the deduction even at higher incomes. Your CPA can run the actual limit.

State taxes and the PTET

The federal deduction for state and local taxes is capped at $40,400 for 2026, with the cap reduced at higher incomes. Many states let pass-through entities pay state income tax at the entity level, called a pass-through entity tax or PTET, which may let the business deduct it. It's still available in states that offer it; confirm the details with your CPA.

Texas has no personal income tax, so the PTET doesn't come up there. The Texas franchise tax generally applies to LLCs and corporations alike, so the entity choice doesn't avoid it.

What does the tax difference look like in dollars?

Here's an illustrative example. A manufacturer has $1,000,000 of taxable profit after the owner's salary. We'll assume the owner is in the top 37% federal bracket, the full 20% QBI deduction is available, and we'll ignore state tax and payroll tax to keep it simple.

Item (illustrative)	Pass-through (S corp or LLC)	C corp, profit retained	C corp, profit paid out
Company tax	$0	$210,000	$210,000
Owner tax	$296,000	$0 now	$188,020
Total federal tax	$296,000	$210,000	$398,020

The pass-through number is $1,000,000 less the 20% QBI deduction, or $800,000, times 37%. The C corp payout column is $1,000,000 times 21%, then the remaining $790,000 taxed at 23.8% as a dividend.

So if you pay out most of your profit, the pass-through usually wins. If you reinvest nearly everything for years, the C corp can defer tax. But retained profit taxed later, often at sale, can cost more. And remember that pass-through owners need cash to pay their tax, so many S corps and LLCs make tax distributions every quarter.

Does entity type matter when you raise capital or sell?

For bank debt, not much. Lenders look at cash flow, collateral and guarantees. They don't care much whether you're an LLC or a corporation.

For outside equity, it matters more. An S corp can have no more than 100 shareholders, only one class of stock, and generally only U.S. individuals and certain trusts and estates as owners. A private equity fund or another company can't own S corp stock. So a minority investment from a fund usually requires a restructuring first.

For a sale, structure affects price. Many buyers prefer to buy assets, or an LLC interest, because they get a step-up in the tax basis of the assets. That creates future depreciation deductions. A buyer of C corp stock usually doesn't get that. Buyers may pay less for stock, or push for an asset sale, which can mean two levels of tax for a C corp seller. Many buyers price off EBITDA, but the after-tax proceeds can be very different depending on structure. Our guide to getting your financials ready to sell covers the financial side of a sale.

What about QSBS?

Qualified small business stock, under Section 1202, can let owners of certain C corporations exclude gain when they sell. The 2025 law expanded it for stock acquired after July 4, 2025. Owners can exclude 50% of the gain after three years, 75% after four and 100% after five. The cap per company is the greater of $15 million or ten times basis, and the company's gross assets can't exceed $75 million when the stock is issued.

Manufacturing is generally a qualifying business for QSBS. That makes a C corp worth a fresh look for a manufacturer planning a sale five or more years out. But there are many conditions, converting an existing company has its own rules, and the clock starts when the stock is issued. This is a conversation to have with your CPA and attorney, not a reason to convert on your own.

How complex is each structure to run?

An LLC taxed as a partnership needs a good operating agreement and partnership tax returns. Capital accounts and special allocations can get complicated with several owners.

An S corp needs payroll for owners, a reasonable salary that holds up, and distributions in proportion to ownership. Uneven distributions can risk the S election, so this needs care.

A C corp needs corporate formalities and its own tax return. It's simpler on ownership because it can have any number and type of shareholders and classes of stock.

Whatever you pick, the monthly accounting looks similar. Clean books, accrual basis, a real inventory number and a monthly close matter more than the entity type.

How do benefits and equity compensation differ?

Health insurance for owners who hold more than 2% of an S corp is included in their wages, with a deduction on the personal return. In a C corp, owner health coverage can generally be a tax-free benefit.

Retirement plans work in all three. For 2026, the 401(k) employee deferral limit is $24,500, with an $8,000 catch-up for those 50 and over. The total limit per person, including employer contributions, is $72,000.

For equity to key people, an LLC can issue profits interests. An S corp is limited to one class of stock, so phantom stock is common. A C corp can issue options and preferred stock. Our post on allocating equity in a manufacturing company covers these tools.

Can you convert between structures later?

Yes, but some moves are much easier than others.

• LLC to S corp tax status: usually just an election on Form 2553.
• S corp to C corp: revoke the election. You generally can't re-elect S status for five years.
• C corp to S corp: possible, but gain built into assets at the switch can be taxed if sold within five years.
• C corp to LLC: generally treated as a liquidation, which can trigger tax on the company and the owners.
• LLC to C corp: usually a tax-free move, often done before a QSBS plan or an outside investment.

Because some of these are costly, I'd make the choice with a three-to-five-year view, not just this year's tax return.

How should a growing manufacturer decide?

An LLC taxed as a partnership fits if you have several owners with different contributions, you want flexible profit splits, or you hold real estate or equipment that you lease to the operating company.

An S corp fits if you're an owner-operator, you take out a good share of profit each year, all owners are U.S. individuals, and you don't expect a fund to invest directly.

A C corp fits if you'll reinvest most profit for years, you plan a sale far enough out to use QSBS, or you expect an outside investor that can't own S corp stock.

Many manufacturers end up with two entities: an operating company and a separate LLC that owns the building. That keeps the real estate out of a future sale and gives the owner rent income. It also needs a proper lease at market rent.

I think the best approach is to model it. Take your last two years and next two years of expected profit, distributions and capital spending, and run them through each structure with your CPA. Our manufacturing tax strategy work does that modeling, and we work with your CPA on the filing side. For the 2025 law changes in more detail, see our post on OBBBA tax provisions for manufacturers.

Frequently Asked Questions

Is an LLC or a corporation better for a manufacturer?

For many owner-run manufacturers, a pass-through (an LLC or an S corp) is the better fit. A C corp fits when you'll reinvest most profit or plan a sale that can use QSBS.

Is the 21% corporate rate permanent?

The 21% rate has no expiration date in the tax code. Congress can still change it, as with any tax rate.

Is the 20% QBI deduction still available?

Yes. The 2025 law made it permanent. Above certain income levels it's limited by wages paid and qualified property, which many manufacturers have.

Can a private equity firm invest in my S corp?

Not directly. S corps can't have partnerships or corporations as shareholders, so a restructuring is usually needed before the investment.

Should I change my entity before I sell?

Possibly, but start early. Some changes trigger tax or waiting periods, so talk with your CPA and attorney several years ahead.
