Why Form an LLC? Protection, Tax Treatment

Look. Most of the small-business owners we talk to fall into one of two buckets.

The first bucket has an EIN, a DBA filed at the county, and a business bank account in the DBA name. They think they’re “set up.” They’re not. They’re a sole proprietor. They just have a tax ID and a registered nickname.

The second bucket doesn’t have any of that. They’re at the farmer’s market on Saturday. They post on Instagram. They take Zelle payments, maybe a Square reader. They think the IRS doesn’t see them as a business, since they haven’t “registered anything.” They’re already a sole proprietor by default: they just have no legal separation between their business activity and their personal life.

Both groups eventually ask us the same question: should I form an LLC, and what does it actually do?

This article gives you a straight answer. No LegalZoom upsell. No “it depends” cop-out.

#What “sole proprietor” really means (whether you signed anything or not)

The first thing to understand: you don’t have to register to be a sole proprietor. In the U.S., sole proprietorship is the default legal status for one person making money from a business. The moment you take your first payment for a product or service, you are operating a business. The IRS sees you that way, whether you’ve filed paperwork or not.

#The default rule

If you sell candles at a market and make a profit, that income goes on Schedule C. You owe self-employment tax once your net earnings reach $400. Whether you owe income tax depends on your total income. You must report the income even if you are paid in cash. Skipping the return doesn’t make the income disappear. It just turns into a problem once it gets discovered.

#An EIN is a tax ID, not an entity

An Employer Identification Number is a 9-digit ID. The IRS uses it to route your business taxes. That’s it. Sole props can get EINs, and probably should, so they don’t have to put their SSN on every W-9. Getting an EIN does not form an entity. It does not create liability protection. It does not change your tax treatment. You’re still a sole prop, just one with a tax ID.

#A DBA is a name registration, not an entity

A “Doing Business As” is a county-level filing. It says, “I, John Smith, also do business as ‘John’s Coffee Roasters.’” It lets you open a business bank account in that name. You can put it on invoices too. It is not a separate legal person. It does not protect you from anything. When John’s Coffee Roasters gets sued, John Smith personally gets sued. John’s Coffee Roasters is just a nickname for John Smith.

#The combination doesn’t change the math

EIN + DBA + business bank account = a sole proprietorship with a tax ID, a registered nickname, and a separate bank account. That’s cleaner books than nothing. But it’s still zero legal separation from you personally. If someone slips on a wet floor at your booth, they sue you, not your DBA.

#What an LLC actually adds

Forming a limited liability company creates a new legal person under state law. The LLC owns the business assets. It signs contracts in its own name. It holds the bank account. It stands between you and the business’s liabilities. Two real things change:

#Limited liability: a wall between business and personal

If your LLC is sued, the plaintiff can come after the LLC’s assets: the bank balance, the equipment, the inventory, the receivables. They generally cannot come after your house, your personal savings, or your car. That’s the wall. It’s the single biggest reason owners form LLCs. For a lot of small operators, it’s worth the formation cost on the day they take their first liability-bearing job.

This protection isn’t absolute. We’ll cover the four ways it disappears in the next section. But for the routine risks of running a small business, it does what it advertises. Think a customer injured by your product, a contract dispute with a vendor, or a defaulted business credit card.

#A separate legal person that holds your contracts

Your LLC signs contracts in its own name. It hires contractors as the LLC. It enters lease agreements as the LLC. Over time this builds a separate paper trail and credit profile for the business. That matters later, when you want a business credit card, a line of credit, a real lease, or an SBA loan. As a sole prop, all of that flows through your personal credit. As an LLC operated correctly, the business builds its own.

#A vessel you can change the tax treatment of later

This is the part most owners misunderstand. An LLC is a state-law entity. It has no federal tax classification of its own. A single-member LLC is taxed as a sole proprietor by default (Schedule C). A multi-member LLC is taxed as a partnership by default (Form 1065). Either can elect to be taxed as an S-corp or a C-corp instead.

The LLC is the chassis. You bolt the tax classification on top. You can start as a single-member LLC paying Schedule C taxes, then later elect S-corp status once income justifies it. That flexibility is what makes the LLC the default vessel for most small operators.

#When the protection disappears (the four ways you lose the veil)

The LLC’s liability wall isn’t a one-way force field. In specific situations, courts can “pierce the corporate veil”: reach through the LLC and hold the owner personally liable. Two things can put your own money at risk even when the LLC is run well: you can be sued for your own acts, and you are liable for any debt you personally guaranteed. Two more can let a court ignore the LLC:

• Co-mingling funds. This means running personal expenses through the business account, or business expenses through the personal account. It’s the single biggest reason small-business LLCs lose veil protection. The LLC isn’t a separate person if you treat it like a wallet.
• Undercapitalization or fraud. This means forming an LLC the day before a foreseeable lawsuit to hide assets. It also means running an LLC with no real cash on hand while signing contracts you couldn’t possibly perform.
• Personally guaranteeing business debt. A lot of vendors and landlords require personal guarantees. When you sign one, you voluntarily put your personal assets behind that specific obligation. The LLC doesn’t protect you from the thing you personally guaranteed.
• Personal acts. Say YOU personally injure someone: you drive the company van into a pedestrian, or write a defamatory review of a competitor. You can be sued personally for what you did, regardless of whether the LLC was involved. The LLC protects you from the LLC’s bad acts, not your own.

Just so you know: co-mingling funds is the one most small operators violate. Operating an LLC like a properly separate person is what keeps the wall standing. Run it like a wallet, and it’s not really an LLC anymore.

#The tax answer (this is where most owners are confused)

We get this question constantly: “How much will an LLC save me in taxes?”

By itself, nothing.

#Default LLC = same Schedule C you’d file as a sole prop

A single-member LLC’s default tax treatment is “disregarded entity.” That means the IRS ignores the LLC for income tax purposes. You file the exact same Schedule C. Same income, same expenses, same self-employment tax you would have filed without the LLC. Forming the LLC did not change your federal tax bill by one dollar.

This surprises people who heard “LLC saves you taxes” from a friend or a YouTube ad. It doesn’t. What saves you taxes is changing your tax classification. The LLC makes that possible, but it doesn’t do it for you.

#The S-corp election is where the tax savings live

Once your business has real net income, often $50K to $80K of net profit, you can file Form 2553. The exact number depends on the salary the IRS would call fair. This lets your LLC be taxed as an S-corporation instead of as a sole proprietor. That election changes the math a lot:

• A portion of your net income gets paid as a reasonable salary subject to payroll tax (~15.3% of that salary)
• The remaining net income passes through as a distribution, NOT subject to self-employment tax
• At $150K of net profit, an S-corp can cut self-employment tax by roughly $8K to $12K a year before added payroll and filing costs. This only holds if you pay yourself a salary the IRS accepts as fair for your work
• The election does add payroll, a W-2, separate filings, and ongoing compliance costs. So the math has to work

We have a separate article on the break-even thresholds and full math by income level. The short version: don’t elect S-corp the day you form the LLC. Form the LLC first, run as a single-member LLC for the first year or two, and elect when the income justifies the added admin.

#The LLC is the ramp; the S-corp is the savings

This is the framing we walk through on every Discovery call: the LLC gives you the legal protection now, and the option to flip the tax switch later when the math works. Trying to save taxes by forming an LLC alone solves the wrong problem.

#What it actually costs to run an LLC

The cost-of-LLC question depends almost entirely on your state. The federal piece is small. State maintenance is where the variance is.

#Texas (where most of our clients are)

• Formation: $300 filed with the Texas Secretary of State for the Certificate of Formation
• Annual: Texas Public Information Report plus the franchise tax report. No franchise tax is owed if revenue is under $2.65 million for the 2026 report year. The report is still due every year
• Registered agent: $0 if you serve as your own; $100-$200/year if you use a commercial service
• Total year-1: ~$300-$500; ongoing: $0-$200/year

#California

• Formation: $70 filed with the California Secretary of State
• Annual: $800 minimum LLC franchise tax owed every year, regardless of revenue
• Statement of Information: $20 every other year
• Total year-1: ~$870; ongoing: ~$800/year

The California franchise tax is the single biggest reason we sometimes recommend forming a single-member LLC in a different state. We only do this for a real reason, not just to dodge the $800. Forming out of state to operate in state creates its own problems: foreign qualification, double registration, and more.

#BOI / FinCEN reporting: no longer required for U.S. LLCs

This requirement got a lot of attention in 2024. FinCEN made this permanent in August 2026. U.S. companies, including LLCs formed in the U.S., do not file a BOI report. Foreign companies that register to do business here still file for their foreign owners. The noise from 2024 has settled.

#Ongoing operational cost

Beyond the state fees, running an LLC means:

• Separate business bank account (most small banks free; check Relay or Bluevine for online options)
• Bookkeeping that keeps business and personal separate every month
• Annual tax return: still a Schedule C if single-member default, but cleaner and easier when the books are clean
• State filings on time: most states will administratively dissolve your LLC if you skip the annual report for one or two years

#What it costs if we run the formation for you

The numbers above are state filing fees: what the state charges to process the paperwork. They’re the cheapest part of forming an LLC, and the part DIY owners usually get right. The expensive part is everything around the filing. This is where DIY formations go sideways. Common gaps: wrong responsible party on the EIN, no operating agreement, no separation-of-funds discipline, no S-corp timing decision, no clear year-one compliance rhythm.

Our standard LLC formation engagement is $2,250, which covers the full setup so you’re ready to operate from day one:

• State filing in your state of operation. We file the Certificate of Formation (or equivalent) for you
• EIN application filed correctly: responsible party, business activity code, fiscal year, all set so the IRS doesn’t bounce notices to you later
• Standardized operating agreement template. We’re not attorneys and we don’t draft custom legal documents. But you’ll walk away with a defensible template covering single-member, multi-member, or husband-wife structures. Use it as-is, clean it up with an attorney later, or both. Either way, you’re not operating with nothing in place
• Business bank account setup, usually with Relay (online business banking that plays well with our bookkeeping workflow)
• Bookkeeping setup so you’re clean from day one: chart of accounts, bank feed connected, separation-of-funds discipline locked in before you take your first deposit
• 1-hour LLC Mastery consultation with our managing partner, covering what to do, what to avoid, and how to stay compliant year-round. We also flag when the S-corp election conversation will fit once your income justifies it
• Registered agent service: first year included free; $300/year thereafter. For Texas entities, the $300 also covers filing your annual Public Information Report (PIR) so you don’t get administratively dissolved

This is a full setup. What you’re paying for isn’t the $300 of state paperwork. You’re paying for a managing partner to walk you through how to actually run the thing once it exists. The bank, books, and compliance pieces are all in place before you take your first dollar.

If you need ongoing support after the formation engagement (advisory, bookkeeping, tax prep), that’s a separate engagement we can talk through. The formation package gets you set up successfully. Staying with us after that is your call, not the package’s default.

If the math doesn’t pencil for a full engagement, we’ll tell you. Some folks are better off filing the state paperwork on a Saturday morning. They bring us in later, only for the bookkeeping setup or the S-corp timing call. Free advice either way on whether the DIY path fits your situation.

#When the LLC move stops being optional

We don’t recommend forming an LLC on day one of every side hustle. Sometimes the right answer is to operate as a sole prop with clean books for the first year. See if the business has legs, then form. But there are specific lifecycle moments where the LLC move becomes harder to defer:

#You’re operating in public with physical risk

Think vendor markets, festivals, pop-ups, conventions, trade shows, in-person events. The moment you have a customer-facing physical presence (booth, table, sample table), the slip-and-fall risk and the product-liability risk are real. An LLC is cheap insurance compared to the alternative.

#You’re signing contracts, leases, or vendor agreements

Any time your business name is on a document that obligates you to pay or deliver, you want that signature to be the LLC’s. Not yours personally. Think a wholesale order, a venue rental, a contractor agreement, a co-packing arrangement. Otherwise you’re personally on the hook for every breach.

#Revenue is consistent and growing

Once you’re consistently doing $30-50K+ in revenue and the trajectory is up, the cost of the LLC is rounding error against the income. That’s $300-$800 to form, with varying maintenance after. It also sets up the S-corp election conversation a year or two ahead of when you’ll need it.

#You’re considering hiring or taking on partners

The day you bring on a second owner, a partner, or your first W-2 employee, the LLC stops being optional. Multi-owner businesses need a clear ownership structure, an operating agreement, and a legal entity that owns the relationships. Not three friends with a shared Square account.

#Common questions

Do I need an LLC if I’m just selling at the farmer’s market on Saturday? You don’t legally need to form one. But say a customer slips, sues, and finds out you have no entity. They sue you, and that means your personal assets are exposed. For most market sellers, the $300-$500 Texas LLC cost is the cheapest insurance policy you’ll ever buy.

I have an EIN as a sole prop: doesn’t that count as forming a business? No. An EIN is a tax ID. The IRS issues EINs to sole proprietors so they don’t have to put their SSN on every W-9 they fill out. It does not create a separate legal entity. It does not provide liability protection. It does not change your tax treatment.

I have a DBA filed at the county: am I protected? No. A DBA (“doing business as”) is a public record that you, personally, are conducting business under a trade name. It’s a transparency filing, not a liability shield. If someone sues “John’s Coffee Roasters,” they’re really suing John.

What’s the actual difference between an LLC and an S-corp? An LLC is an entity type, set up at the state level. An S-corp is a tax classification, chosen at the federal level by filing Form 2553. An LLC can elect to be taxed as an S-corp. They’re not competing options. They’re stacked. Most of our clients end up as an LLC taxed as an S-corp once income justifies it.

How much does an LLC actually save me in taxes? By itself, zero. The tax savings come from electing S-corp tax treatment, which the LLC makes possible. See our LLC vs. S-corp tax math article for the break-even by income level.

Can I form an LLC online and skip the lawyer? For a single-member LLC in your home state, yes. The formation paperwork is short and the state forms are straightforward. Don’t skip having something in place for an operating agreement. Even a standardized template beats nothing. Also don’t skip the separate-bank-account / clean-books discipline that keeps the LLC actually functioning as an LLC. Most LegalZoom-only LLCs we audit are missing one or both. If you want a custom operating agreement drafted, that’s an attorney conversation. We’re not a law firm, but we can point you in the right direction.

What state should I form in? For 95% of small operators, the answer is “the state you actually live and operate in.” The Delaware or Nevada formation strategy applies only to specific scenarios. Think outside investment, or multi-state operations with real nexus questions. It does not apply to a one-person business in Texas.

I formed an LLC two years ago and never filed the annual report, am I in trouble? Maybe. Most states will administratively dissolve an LLC after one or two missed annual reports. If your LLC has been administratively dissolved, you’ve been operating without limited liability protection for the period between dissolution and reinstatement. Reinstatement is usually possible, but it costs a few hundred dollars in back fees. Worth fixing now.

What’s this BOI / FinCEN report I keep hearing about? The Beneficial Ownership Information report was required for most LLCs in 2024 under the Corporate Transparency Act. After multiple court rulings, FinCEN issued an interim final rule on March 26, 2025 that removed the requirement for all U.S.-formed entities. As of now, domestic LLCs don’t file. Foreign-formed entities registered to do business in the U.S. still do. The rule is interim, so check current FinCEN guidance if you’re forming a brand-new LLC, but the 2024 panic has settled.

When should I think about the S-corp election? Once net income (revenue minus all your business expenses) reaches roughly $50K and trends upward. We run the math for every client at Discovery. For most owners, the break-even where the S-corp election starts paying for its own admin is somewhere between $50K-$80K of net income. We don’t do surprises on this. We walk through the math openly before you elect.

#Ready to talk through whether the LLC move fits your setup?

The honest answer to “do I need an LLC” depends on three things: what you’re doing, what you’re earning, and where you want this business to go in the next 2-3 years. For some folks the answer is “yes, this week.” For others it’s “not yet. Let’s set up clean books first and form when revenue justifies it.”

Either way, the math + the protection question + the eventual S-corp ladder are easier to walk through together than to figure out alone.

Book a 20-minute Tax Discovery: Google Meet, no pitch, free advice either way. If LLC formation (and the S-corp election that often follows) is your move, we’ll walk you through what the engagement looks like. If it’s not yet, we’ll tell you what is.
