Sole Proprietorship vs LLC: Which Is Right for Your Business?

No, not by itself — and this is one of the most common misconceptions among new business owners. A single-member LLC is treated as a “disregarded entity” by the IRS, which means the tax code literally ignores the LLC wrapper. All your business income and expenses flow directly onto Schedule C of your personal Form 1040, exactly the same way they would if you operated as a sole proprietorship with no entity at all. Same line items, same deductions, same self-employment tax calculation. The IRS does not care whether you filed articles of organization with your state. From a federal tax perspective, forming an LLC by itself changes absolutely nothing.

The self-employment tax situation is identical too. As a single-member LLC (or sole proprietor), your net self-employment income is subject to the 15.3% combined Social Security and Medicare tax on the first $176,100 of earnings (2025 figure), plus 2.9% Medicare tax on anything above that. If you earn $120,000 in net profit from your LLC, you’ll pay roughly $16,956 in self-employment tax on top of your regular income tax. That number would be exactly the same without the LLC.

So why do people keep saying LLCs save money on taxes? Usually because they’re conflating two separate decisions. The LLC is a legal entity — it gives you liability protection, separates your personal assets from business debts, and gives you a more professional structure. The tax savings come from a completely different move: electing S-corp treatment by filing Form 2553 with the IRS. When your LLC elects S-corp status, you pay yourself a reasonable salary and take the remaining profit as distributions, which are not subject to self-employment tax. That’s where the savings come from — the S-corp election, not the LLC formation.

Here’s an example. Say you run a marketing consulting business that nets $150,000 per year. As a sole proprietor or single-member LLC (no S-corp election), your self-employment tax is approximately $21,194. Now suppose you elect S-corp treatment and pay yourself a reasonable salary of $80,000. The payroll taxes on that salary (employer and employee combined) are about $12,240. The remaining $70,000 passes through as a distribution with no self-employment tax. Your total payroll tax burden drops from $21,194 to $12,240 — a savings of about $8,954 per year.

But the S-corp election isn’t free. You now need to run payroll ($500 to $2,000 per year through a service like Gusto or ADP), file a separate Form 1120-S corporate tax return ($1,000 to $3,000 in accounting fees), and deal with quarterly payroll tax deposits and W-2 filings. If your net income is below $50,000 to $60,000, those costs can eat up most or all of the tax savings.

There are some indirect tax benefits that come from having an LLC, but they’re not unique to the LLC structure. For example, having a separate business entity makes it easier to keep clean records, which in turn makes it easier to claim legitimate deductions. But a sole proprietor with a dedicated business bank account and good bookkeeping can claim the same deductions. The LLC doesn’t open up any deductions that weren’t already available.

Multi-member LLCs are a different story. By default, a multi-member LLC is taxed as a partnership, filing Form 1065 with each member receiving a Schedule K-1. Partnership taxation brings its own set of rules — guaranteed payments, special allocations, inside basis versus outside basis — that are fundamentally different from sole proprietorship taxation. If you’re going into business with a partner, the LLC provides both legal structure and a different tax framework. But if you’re a solo operator, the LLC alone does not change your tax situation.

One more thing worth mentioning: some states impose additional taxes or fees on LLCs that sole proprietorships don’t face. California charges an $800 annual franchise tax on all LLCs regardless of income. Texas applies its franchise (margin) tax to LLCs with gross receipts above $2.65 million. New York requires LLCs to publish in two newspapers for six weeks, costing $300 to $1,500. These are costs you wouldn’t incur as a sole proprietor. So in certain states, forming an LLC could actually increase your costs without any offsetting tax benefit.

The bottom line: form an LLC for the legal protection and business credibility. Don’t form one expecting a tax break, because you won’t get one unless you take the additional step of electing S-corp treatment — and even then, run the numbers with a CPA to make sure the savings justify the added complexity. Read our full guide on S-corp elections to decide whether that next step makes sense for your business.

To put actual numbers on this: a freelance photographer earning $95,000 in net income as a sole proprietor pays roughly $13,413 in self-employment tax on Schedule C. If they form an LLC and do nothing else, they still pay $13,413 — the LLC changed nothing tax-wise. Now, if that same photographer forms an LLC and elects S-corp status, sets a reasonable salary of $55,000, and takes the remaining $40,000 as distributions, the employment tax drops to about $8,415 (employer and employee shares on the $55,000 salary). That is a savings of roughly $4,998 per year. But the photographer also now has payroll costs ($500 to $2,000 annually for a payroll service), a separate business tax return filing (Form 1120-S, which might cost $1,000 to $2,500 in preparation fees), and more bookkeeping obligations. At $95,000 in net income, the math works in favor of the S-corp election after accounting for the added costs. Below about $50,000 in net income, it usually does not.

The point is that the LLC formation itself — filing articles of organization, getting an EIN, opening a business bank account — has zero direct tax impact for most small business owners. It is a liability protection decision first and foremost. The tax benefits only appear when you pair the LLC with a specific tax election, and even then, those benefits depend on your income level, your industry, and how your state taxes the entity.

The state filing fee for articles of organization is $200, payable to the New York Department of State. But that’s just the starting point. New York has some of the highest LLC formation costs in the country, mainly because of the publication requirement — and the total first-year bill can range from $600 to $2,000 or more depending on where you form.

Let’s break it down piece by piece. After filing your articles of organization, New York requires every new LLC to publish a notice of formation in two newspapers — one daily and one weekly — in the county where the LLC’s office is located, for six consecutive weeks. This is mandated by Section 206 of the New York Limited Liability Company Law, and it is not optional. After publishing, you file a Certificate of Publication with the state (another $50 fee). The publication costs vary wildly by county. In Manhattan (New York County), the newspaper fees have historically run $1,200 to $1,600. In Albany, you might pay $400 to $600. In some upstate counties, the cost can be as low as $200 to $300.

This publication requirement has been a sore spot for small business owners for years. The 2022 amendment to the LLC law reduced the pain somewhat — LLCs formed after January 1, 2021, no longer have their authority to do business suspended for failing to publish, but they still must comply eventually. The practical consequence of not publishing is that your LLC can’t bring or defend lawsuits in New York courts until the publication requirement is satisfied. That’s a meaningful limitation if you ever need to enforce a contract or defend against a claim.

Next, you’ll need a registered agent. Every LLC in New York must designate a registered agent — a person or company authorized to receive legal service of process and official state notices on behalf of the LLC. You can serve as your own registered agent if you have a physical address in New York, but many people prefer to use a commercial registered agent service, which runs $50 to $300 per year. Using a service keeps your personal address off the public record and ensures that someone is always available during business hours to accept legal documents.

An operating agreement is technically not required to be filed with the state, but New York law (LLC Law Section 417) requires that every LLC — even single-member ones — have a written operating agreement. You can draft a basic one yourself using templates, or hire an attorney to prepare a customized agreement for $300 to $500. If your LLC has multiple members, an attorney-drafted agreement is strongly recommended because it governs profit distributions, voting rights, management structure, and what happens if a member wants to leave or dies.

You’ll also need an Employer Identification Number (EIN) from the IRS. This is free — you can apply online at IRS.gov and receive your EIN immediately. Do not pay a service to obtain your EIN. The process takes five minutes. You’ll need the EIN to open a business bank account, file taxes, and hire employees.

Speaking of bank accounts, most banks offer free or low-cost business checking accounts. Chase, Bank of America, and most local credit unions have accounts with no monthly fee or low minimum balance requirements. Budget $0 to $25 per month depending on the bank and your transaction volume.

Beyond the startup costs, there are ongoing annual costs to consider. New York requires LLCs to file a biennial statement with the Department of State every two years ($9 fee — yes, nine dollars). If your LLC earns income, you’ll file a New York State tax return: Form IT-204-LL for the annual filing fee (minimum $25, up to $4,500 depending on gross income from New York sources) and Form IT-204 if the LLC has multiple members. Single-member LLCs report on their owner’s personal New York return.

If your LLC elects S-corp treatment, you’ll also file New York Form CT-3-S and potentially the New York Pass-Through Entity Tax (PTET) election to work around the federal SALT cap. The PTET can save high-income LLC owners thousands of dollars per year, but it adds another layer of compliance.

Here’s a realistic first-year budget for forming an LLC in New York:

State filing fee: $200. Publication costs: $300 to $1,500 (county dependent). Certificate of Publication: $50. Registered agent: $50 to $300. Operating agreement: $0 to $500. EIN: $0. Business bank account: $0 to $25/month. Total first-year cost: roughly $600 to $2,575.

For comparison, forming an LLC in some other states is dramatically cheaper. Wyoming and Delaware charge $100 or less with no publication requirement. Florida charges $125. But forming in a different state to save money usually backfires — if you operate in New York, you still need to register as a foreign LLC in New York (another $250 filing fee), plus you’ll pay registered agent fees in both states. Form your LLC in the state where you actually do business. Reach out to our team if you need help setting up your New York LLC correctly from the start.

Here is a rough cost breakdown for a New York LLC in the first year. The Articles of Organization filing fee with the state is $200. The publication requirement — which New York uniquely requires — can run anywhere from $300 in cheaper counties to $1,500 or more in Manhattan, depending on the newspaper rates. After publication, you file a Certificate of Publication for another $50. An EIN from the IRS is free. If you hire an attorney to draft an operating agreement, that typically costs $500 to $1,500 for a straightforward single-member LLC. Annual maintenance includes a biennial statement filing with the state for $9, plus any city or county business licenses. All told, first-year costs in New York typically fall between $1,000 and $3,000, with the publication requirement being the biggest variable.

Compare that to forming an LLC in a state like Wyoming, where the filing fee is $100 and there is no publication requirement. Some New York business owners form their LLC in Wyoming or Delaware for the lower cost and perceived legal advantages, then register as a foreign LLC in New York anyway — and end up paying both states’ fees. In most cases, if you are physically operating in New York and serving New York clients, forming the LLC in New York is simpler and no more expensive once you account for the foreign qualification fees.

Yes, and this is one of the most common transitions in small business. Plenty of people start out as sole proprietors because it’s the path of least resistance — no paperwork to file, no formation fees, no operating agreement to draft. You just start doing business. Then the business grows, the revenue increases, the clients get bigger, and suddenly you realize you need the legal protection that comes with having a formal entity between you and your business liabilities. That’s when the LLC conversation happens.

The good news: switching from a sole proprietorship to an LLC is straightforward, and there’s no taxable event triggered by the conversion. Since a single-member LLC is treated as a disregarded entity by the IRS, the tax treatment before and after is identical. You file Schedule C on your Form 1040 either way. The IRS doesn’t even require notification that you’ve formed an LLC if you keep the same EIN (more on that in a moment).

Here’s the step-by-step process. First, you file articles of organization (or a certificate of formation, depending on your state) with your state’s Secretary of State office. In New York, the filing fee is $200. In Florida, it’s $125. Most states process the filing within a few business days, though expedited processing is usually available for an extra fee.

Second, handle the EIN question. If you were operating as a sole proprietor and already had an EIN, you can sometimes continue using it — but the IRS generally recommends getting a new EIN when you change your business structure. If you were using your Social Security number as your tax ID (which many sole proprietors do), you’ll definitely want to get an EIN now. Apply free at IRS.gov — the process takes about five minutes and you receive the number immediately.

Third, open a business bank account in the LLC’s name. This is non-negotiable. One of the main reasons people form LLCs is liability protection, and the fastest way to lose that protection is to commingle personal and business funds. If a plaintiff can show that you treated your LLC’s bank account as your personal piggy bank — paying personal expenses from it, depositing personal income into it, never maintaining a clear separation — a court can “pierce the corporate veil” and hold you personally liable for business debts. Open a separate account, get a separate debit card, and keep clean records.

Fourth, update your contracts and client agreements to reflect the new entity name. Any new contracts should be signed in your capacity as a member or manager of the LLC, not in your personal name. Old contracts don’t automatically transfer to the LLC, so you may need to execute assignment agreements with existing clients or vendors. Some clients, especially larger companies, may require updated W-9 forms reflecting the LLC’s name and EIN.

Fifth, check your insurance. Your existing general liability, professional liability, or errors and omissions insurance policy may have been issued to you individually. You’ll want to update it to name the LLC as the insured. Some insurers handle this with a simple endorsement. Others may rewrite the policy. Don’t skip this step — if the LLC is sued and the insurance policy names you personally rather than the LLC, coverage could be denied.

Sixth, if you’re in a state with specific LLC requirements, handle those. In New York, that means the publication requirement (publishing notice in two newspapers for six weeks — budget $300 to $1,500). In states with annual report requirements (most of them), mark your calendar for the filing deadline. In California, register with the Franchise Tax Board and budget for the $800 minimum annual franchise tax.

The timing question comes up a lot: when should you make the switch? There’s no single right answer, but here are some guideposts. Many CPAs suggest forming an LLC once your business income exceeds $30,000 to $50,000 per year, or once you start working with clients who could potentially sue you for significant amounts. If you’re a freelance graphic designer making $20,000 on the side, the formation and maintenance costs may outweigh the benefits. If you’re a consultant billing $150,000 per year and advising companies on decisions worth millions, the liability exposure alone justifies the LLC.

There’s also a mid-year timing consideration. You can form an LLC at any point during the year — there’s no requirement to start on January 1. From a tax perspective, the transition is smooth because the IRS treats the single-member LLC the same as the sole proprietorship. Your Schedule C for the year will include all business income and expenses for the full year, regardless of when during the year you formed the LLC.

One more thing: forming the LLC is often step one of a two-step process. Once the LLC is up and running and your income justifies it, the next step is often electing S-corp tax treatment by filing Form 2553. The LLC gives you legal protection. The S-corp election gives you tax savings. They work together, but they’re separate decisions made at separate times. Talk to our team if you want help deciding when to make each move.

The transition process also has a few practical considerations that people skip over. When you form the LLC, you need a new EIN — you cannot reuse your sole proprietorship’s EIN (or your Social Security number) for the new entity. That means notifying every client and platform where you receive payments. If you use payment processors like Stripe, Square, or PayPal, you’ll need to update your business information and EIN with each one. Bank accounts need to be changed over — you should open a new business checking account in the LLC’s name and close the old sole proprietorship account once all outstanding transactions clear.

Your existing contracts and agreements should be assigned to the LLC as well. If you have a commercial lease, vendor contracts, or client service agreements in your personal name (as a sole proprietor), you’ll want to execute assignment agreements transferring them to the LLC. Some landlords and vendors will require consent before allowing the assignment, so build in time for that. And don’t forget about business licenses and permits — many cities and counties require you to update or re-apply when the legal structure of your business changes. In New York City, that means updating your business certificate with the county clerk’s office.

Technically, not every state requires a written operating agreement for a single-member LLC. But you should absolutely have one, and in some states — including New York — it’s actually mandated by law. New York LLC Law Section 417 requires every LLC, regardless of the number of members, to adopt a written operating agreement. Even in states that don’t legally require one, operating without an agreement is like driving without a seatbelt. You might be fine most of the time, but the one time things go sideways, you’ll wish you had it.

Here’s what an operating agreement does for a single-member LLC. First and most important, it establishes that the LLC is a legitimate, separately operated entity — not just a personal bank account with a fancy name. If you’re ever sued and the plaintiff asks the court to “pierce the corporate veil” (hold you personally liable for business debts), one of the factors courts examine is whether you treated the LLC as a separate entity. Having a written operating agreement, combined with a separate bank account, separate books and records, and proper documentation of major decisions, makes it much harder for a plaintiff to argue that the LLC is just an alter ego.

Courts have pierced the veil of single-member LLCs more frequently than multi-member ones, precisely because it’s easier to argue that a one-person LLC is really just the owner operating under a different name. A well-drafted operating agreement helps rebut that argument. In the landmark case In re Albright, the court looked at whether the LLC member had an operating agreement, maintained separate finances, and observed formalities. No operating agreement was one of several factors that led the court to disregard the LLC.

Second, the operating agreement establishes the basic rules for how the LLC operates. Even in a single-member LLC, you should document: how the LLC is managed (member-managed or manager-managed), how capital contributions are made and returned, how profits and losses are allocated, what happens if the member becomes incapacitated or dies, and what the process is for dissolving the LLC. These provisions might seem unnecessary when you’re the only person involved, but they become critical in two scenarios — estate planning and business disputes.

On the estate planning side, your operating agreement should address what happens to the LLC if you die or become permanently incapacitated. Without provisions for succession, your family may face a messy situation where the LLC’s assets are tied up in probate, business operations stall, and clients or vendors are left in limbo. A good operating agreement will name a successor member or manager, outline the process for transferring membership interests, and authorize specific people to manage the business during the transition. This is especially important if the LLC owns real estate, holds contracts with clients, or has employees.

Third, banks and financial institutions often ask for a copy of your operating agreement when you open a business bank account or apply for a business loan. If you don’t have one, some banks will refuse to open the account or will require additional documentation. Lenders and investors almost always want to see the operating agreement before extending credit or making an investment. Not having one signals that the business isn’t being run professionally.

Fourth, the operating agreement can include provisions that protect you from future complications. For example, you can include a provision that prohibits the transfer of membership interests without the member’s written consent — which matters if you ever add a member or sell a portion of the business. You can also include indemnification provisions, limitation of liability clauses, and dispute resolution procedures.

What should a single-member LLC operating agreement include? At minimum: the LLC’s name and principal office address, the member’s name and contribution, the LLC’s purpose, how profits and losses are allocated (100% to the single member, obviously), the member’s authority to manage the LLC, provisions for adding new members, what happens upon death or incapacity of the member, the process for dissolution, and a statement that the LLC is governed by the operating agreement and applicable state law.

You have two options for getting one. You can draft it yourself using templates available online — LegalZoom, Rocket Lawyer, and the SBA website all have templates. A template-based operating agreement for a single-member LLC can be prepared in 30 to 60 minutes and costs nothing beyond your time. The risk with templates is that they may not reflect your state’s specific LLC laws or your particular business situation.

Alternatively, you can hire an attorney to draft a customized operating agreement. For a single-member LLC, this typically costs $300 to $500 — more for complex businesses or those with significant assets. The advantage is that the attorney can adjust the agreement to your specific needs, ensure compliance with state law, and include provisions you might not think of (like what happens if you want to bring in a partner later).

Whichever route you choose, sign the agreement, keep a copy with your business records, and make sure it’s accessible to your family or estate executor. Update it whenever your circumstances change — new address, new business purpose, change in management structure, or addition of new members. And don’t just sign it and forget it. Review it annually to make sure it still reflects how you actually operate the business. Our team at Reed Corporation can point you toward the right approach for your specific LLC structure.

A good operating agreement for a single-member LLC doesn’t need to be long. A five-to-ten page document covering the basics — member identity and capital contributions, profit allocation, management authority, restrictions on transferring membership interests, dissolution procedures, and a statement that the member’s liability is limited to their capital contribution — is usually sufficient. Templates exist online, but they vary in quality. The issue with generic templates is that they often include provisions designed for multi-member LLCs (like voting procedures and buy-sell clauses) that don’t apply to a single-member entity, or they omit state-specific provisions that New York courts expect to see. Having an attorney review or customize the agreement costs a few hundred dollars and removes any ambiguity about whether the document actually protects you.

This question comes up constantly, and the short answer is: you’re comparing apples and oranges. An LLC is a legal entity type created under state law. An S-corp is a federal tax classification. They exist in completely different categories. An LLC can elect to be taxed as an S-corp. A corporation formed under state law can also elect S-corp status. The LLC and the S-corp election are two separate decisions that work together, and understanding the distinction is the key to making the right choice for your business.

Let’s untangle this. When you form an LLC with your state, you get a legal entity that provides liability protection, allows flexible management structure, and separates your personal assets from your business debts. By default, a single-member LLC is taxed as a sole proprietorship (filing Schedule C), and a multi-member LLC is taxed as a partnership (filing Form 1065). These are the “default” tax classifications. You don’t file anything extra with the IRS — the default applies automatically.

If you then file Form 2553 with the IRS, your LLC elects S-corp tax treatment. The LLC is still an LLC under state law — same articles of organization, same operating agreement, same liability protection. But the IRS now treats it like an S corporation for tax purposes. You file Form 1120-S instead of Schedule C, you pay yourself a salary on a W-2, and any remaining profit passes through as distributions that avoid self-employment tax.

n’t “LLC vs. S-corp” — it’s “should my LLC elect S-corp taxation?” And the answer depends on your income level, your industry, and your tolerance for paperwork.

Here’s the math. As a default-taxed single-member LLC earning $120,000 in net profit, you’ll pay approximately $16,956 in self-employment tax (15.3% on $120,000). If your LLC elects S-corp treatment and you pay yourself a reasonable salary of $65,000, the combined employer and employee payroll taxes on the salary are about $9,945. The remaining $55,000 in distributions has no self-employment tax. Your total payroll/SE tax drops from $16,956 to $9,945 — a savings of about $7,011 per year.

But S-corp treatment adds costs. You’ll need to run payroll — either through a service like Gusto ($40 to $100 per month) or through your accountant. You’ll file quarterly payroll tax returns (Form 941) and annual forms (W-2, W-3). You’ll file a separate corporate tax return (Form 1120-S), which costs $1,000 to $3,000 in accounting fees depending on your CPA. You’ll also need to file state-level S-corp returns in most states. In New York, that means Form CT-3-S plus potentially the Pass-Through Entity Tax election.

Add up the additional compliance costs, and they typically run $2,000 to $5,000 per year above what a default LLC would cost. So your $7,011 in tax savings minus $3,000 in extra costs leaves you with about $4,000 in net benefit. Not bad, but not the windfall some people expect.

At lower income levels, the math doesn’t work. If your LLC nets $40,000, the self-employment tax is about $5,652. If you elect S-corp and pay yourself a $30,000 salary, the payroll taxes are about $4,590 — savings of about $1,062. After $2,000 to $3,000 in additional compliance costs, you’re actually worse off. That’s why most CPAs recommend against the S-corp election until net income consistently exceeds $50,000 to $60,000 per year.

There are also situations where the S-corp election creates complications. S-corps have strict ownership requirements: no more than 100 shareholders, all must be U.S. citizens or residents, only one class of stock. If you plan to raise venture capital, bring in foreign investors, or create different profit-sharing arrangements for different members, the S-corp restrictions become a problem. In those cases, you might want your LLC to be taxed as a partnership (the default for multi-member LLCs) or even elect C-corp treatment.

Another factor: health insurance. If you own more than 2% of an S-corp, you can’t receive health insurance as a tax-free fringe benefit. The premiums must be included in your W-2 wages, and you deduct them on your personal return as a self-employed health insurance deduction. This isn’t necessarily a disadvantage — the net result is usually the same as what a sole proprietor would get — but it adds payroll processing complexity.

Here’s a framework for making the decision. Keep default LLC taxation (Schedule C) if your net business income is under $50,000 to $60,000, you want maximum simplicity, you’re testing a new business idea, or your income is highly variable from year to year. Elect S-corp treatment if your net income is consistently above $60,000, you’re comfortable with payroll compliance, the tax savings after compliance costs are meaningful (at least $3,000 to $4,000 per year), and you plan to stay in the business for the foreseeable future.

One final point: the “LLC vs. S-corp” question sometimes includes a third option — forming a C corporation. Since TCJA set the corporate tax rate at a flat 21%, some high-income businesses benefit from retaining earnings at the corporate level and paying the lower rate. C-corps also qualify for the QSBS exclusion under IRC Section 1202, which can exclude up to $10 million of gain on sale. If you’re building a company with a clear exit strategy, the C-corp structure might be the better long-term play.

The right answer depends on where you are today and where you’re headed. Contact our team to run the numbers for your specific situation — the analysis typically takes one meeting and can save you thousands per year if you’re currently in the wrong structure.

Let’s walk through a concrete comparison. A web developer earning $180,000 in net income operates as a single-member LLC taxed as a disregarded entity. All $180,000 flows to Schedule C, and they owe roughly $25,434 in self-employment tax. If they elect S-corp status, set a reasonable salary of $100,000, and take $80,000 as distributions, the employment tax on the salary is about $15,300 (employer plus employee shares). The $80,000 distribution avoids employment taxes entirely. That is a savings of roughly $10,134 per year — minus payroll processing costs and the additional tax return filing fee.

But the same math doesn’t work at lower income levels. A part-time Etsy seller earning $30,000 in net profit would save very little by electing S-corp status, because the reasonable salary would need to be close to the full $30,000 anyway (leaving almost nothing for tax-advantaged distributions), and the added payroll and filing costs would eat whatever small savings existed. The break-even point varies by industry and location, but as a general guideline, if your net income is consistently below $50,000 to $60,000, the LLC without S-corp election is usually the better fit. Above that range, run the numbers — or better yet, have your CPA run them — because the savings compound every year you stay in the right structure.
