LLC Formation Cost Calculator

About the LLC Formation Cost Calculator

Forming a Limited Liability Company (LLC) is one of the most common steps an entrepreneur takes when launching a new business. Yet the actual cost is rarely just the state filing fee you see listed on the Secretary of State's website. There are registered agent fees, potential attorney costs, operating agreement drafting, federal EIN registration, and — critically — ongoing annual report fees and state franchise taxes that continue for as long as your LLC exists. This calculator adds all of those up so you can make an informed decision before you commit.

What is an LLC and why do entrepreneurs form one?

An LLC is a business structure authorized by state law that combines the liability protection of a corporation with the tax simplicity of a sole proprietorship or partnership. When you form an LLC, the company becomes its own legal entity, which means your personal assets — your home, car, savings — are generally shielded from business debts and lawsuits. For a freelancer, consultant, small retailer, landlord, or startup founder, this separation between personal and business liability is the primary reason to pay the formation fees rather than operate as a sole proprietorship.

Beyond liability, LLCs offer pass-through taxation by default: profits and losses flow directly onto the members' personal tax returns rather than being taxed at a corporate level first. This avoids the "double taxation" that C-corporations face. And unlike S-corporations, LLCs have fewer restrictions on the number or type of owners, making them more flexible for many small businesses.

LLC vs. sole proprietorship vs. corporation

A sole proprietorship costs nothing to start — it is the default structure whenever an individual begins earning money on their own — but it offers no liability protection. If the business is sued, your personal assets are at risk. A general partnership extends this to two or more people with the same problem. An LLC is usually the upgrade path: modest cost, liability protection, and pass-through taxes. A C-corporation provides the strongest liability protection and is preferred for businesses seeking venture capital (since VCs want preferred stock), but it involves double taxation and more complex governance. An S-corporation avoids double taxation but has strict eligibility rules — no more than 100 shareholders, all of whom must be U.S. citizens or residents, with only one class of stock.

Single-member vs. multi-member LLCs

A single-member LLC (one owner) is treated as a "disregarded entity" for federal tax purposes by default — meaning it is taxed exactly like a sole proprietorship on Schedule C. A multi-member LLC is treated as a partnership by default. Both can elect to be taxed as an S-corporation if doing so saves on self-employment tax (more on that below). Multi-member LLCs need a well-drafted operating agreement even more urgently than single-member ones, because it defines what happens if a member wants to leave, how profits are split, and how decisions are made.

The formation process

Forming an LLC involves several distinct steps:

• Choose a state. Most small businesses form in their home state. Forming in Delaware or Wyoming for an LLC that operates entirely in, say, Tennessee usually adds cost rather than saving it — you end up registered in both states.
• Reserve a name. Many states offer optional name reservations for a small fee (often $10–$50). The name must include "LLC," "L.L.C.," or an equivalent and must not be identical to an existing registered business in that state.
• File articles of organization. This is the core formation document, filed with the Secretary of State. It states the LLC's name, registered agent, purpose, and — in some states — the member or manager structure. This is the filing fee shown in the calculator.
• Designate a registered agent. Every LLC must identify a person or entity with a physical street address in the state who will receive legal notices. You can be your own registered agent if you have a physical address in the state, but commercial services ($50–$300/yr) offer privacy and reliability.
• Draft an operating agreement. Though not required to file in most states, an operating agreement is a legally significant internal document that governs how the LLC runs. Without one, disputes default to state default rules, which may not match the members' intentions.
• Get an EIN. The IRS issues Employer Identification Numbers free at irs.gov/ein — the online process takes about 10 minutes. You need one to open a business bank account, hire employees, or file business taxes.
• Open a business bank account. This is not a state requirement but is essential for maintaining the liability protection the LLC affords — commingling personal and business funds can give a court reason to "pierce the corporate veil."

Hidden costs of LLCs

The filing fee is visible, but several recurring costs catch new LLC owners off guard:

• Annual reports and statement of information. Most states charge a fee to file an annual (or biennial) report confirming the LLC's current information. These range from $0 (some states require filing but charge nothing) to $500 per year (Massachusetts).
• Registered agent fees. If you use a commercial registered agent, budget $50–$300 per year indefinitely.
• State franchise taxes or minimum taxes. California charges an $800 minimum franchise tax every year regardless of revenue. Delaware charges an LLC "flat tax" of $300 per year. These are separate from, and in addition to, income taxes.
• New York publication requirement. New York requires new LLCs to publish a notice of formation in two newspapers designated by the county clerk within 120 days of formation. This requirement is unique to New York and can cost $1,000–$2,000 depending on the county — Manhattan is the most expensive, rural upstate counties the cheapest.
• Registered agent change fees. Switching registered agents requires filing a form and paying a fee in most states.
• Foreign qualification fees. If your LLC formed in one state does business in another state, you typically must register as a "foreign LLC" in that other state, paying another filing fee and designating another registered agent there.

Why Delaware is popular — even for LLCs that don't operate there

Delaware's Court of Chancery is the most sophisticated business court in the United States, with centuries of well-developed case law on corporate and LLC disputes. Delaware has no state sales or income tax on companies that operate outside the state, its LLC statutes are highly flexible, and the formation process is fast. For venture-backed startups, Delaware C-corporations are nearly universal because of investor familiarity and the court's predictability.

For a small LLC that operates in another state, however, the calculus is less clear. You will pay Delaware's $90 filing fee and $300 annual LLC tax plus your home state's foreign qualification fee and its registered agent cost. The net result is often more paperwork and more expense without meaningful benefit for a business that will never face complex multi-investor litigation.

California's notorious $800 franchise tax

California imposes an $800 per year minimum franchise tax on every LLC registered in the state, due in the first quarter regardless of whether the business earned any income. New LLCs formed after January 1, 2021 are exempt for the first year, but from the second year forward the $800 is unavoidable until the LLC is formally dissolved. California also charges an additional gross receipts fee for LLCs earning more than $250,000 per year, scaling up to $11,790 for LLCs earning over $5 million. This makes California one of the most expensive states for ongoing LLC costs, even for small businesses.

Choosing a registered agent

Your three broad options are: be your own registered agent (cheapest, but requires a physical address in the state and being available during business hours — your address will be in the public record), use a commercial registered agent service (typically $50–$300/yr, keeps your address private, handles compliance reminders), or have your attorney serve as registered agent (most expensive, but convenient if you already have an ongoing attorney relationship). For most small businesses, a commercial service strikes the best balance of cost and privacy.

What an operating agreement does

An operating agreement is to an LLC what corporate bylaws are to a corporation. It specifies: how profits and losses are allocated among members, how decisions are made and what vote is needed for major actions, what happens when a member wants to sell their interest or dies, how new members can be admitted, and how the LLC can be dissolved. Without an operating agreement, state "default rules" apply — which may distribute profits equally regardless of capital contribution, for example. Even a simple single-member LLC benefits from an operating agreement because it reinforces the separation between personal and business finances.

S-corporation election for tax savings

An LLC can elect to be taxed as an S-corporation by filing IRS Form 2553. This election can save significant self-employment tax once profits exceed roughly $40,000–$60,000 per year, because members can pay themselves a "reasonable salary" (subject to payroll taxes) and take remaining profits as a distribution (not subject to self-employment tax). The trade-off is added payroll complexity and cost — you will need to run actual payroll, file quarterly payroll tax returns, and likely pay an accountant to manage it. The savings typically outweigh the costs once profits pass $50,000–$80,000 per year for a single-member LLC.

When you need an attorney vs. going DIY

DIY filing is entirely workable for a straightforward single-member LLC in most states. The Secretary of State website walks you through the articles of organization, and the IRS EIN application is free and easy. Consider hiring a business attorney when: (1) you have multiple members with unequal contributions or complex ownership splits, (2) you are in a regulated industry (healthcare, financial services, real estate), (3) you need a custom operating agreement with specific buy-sell provisions, (4) you are concerned about personal liability for a specific risk, or (5) you are forming in a state (like New York) with unusual requirements. Attorney fees range from a few hundred dollars for a simple consultation to $1,000–$3,000 for full formation with a custom operating agreement.

Common mistakes when forming an LLC

• Forming in the wrong state. Forming in Delaware when your business operates in California still requires California foreign qualification — and you pay both states' fees.
• Skipping the operating agreement. Especially for multi-member LLCs, this is the document that prevents expensive disputes later.
• Missing the annual report deadline. Most states will administratively dissolve an LLC if it misses its annual report filing. Reinstatement usually costs more than the original fee.
• Commingling personal and business funds. Using a personal account for business expenses — or paying personal bills from the business account — can undermine the liability protection an LLC provides.
• Not getting a separate EIN. Even a single-member LLC should have its own EIN rather than using the owner's Social Security number, for banking and privacy reasons.
• Forgetting about business licenses. An LLC formation does not automatically grant the right to operate in a city. Local business licenses, zoning permits, and professional licenses may also be required.

Series LLCs

Several states — including Delaware, Illinois, Texas, Nevada, and Wyoming — permit a "series LLC," a single LLC with multiple segregated "series" that each hold separate assets and have separate liability protection. This structure is particularly popular for real estate investors who hold multiple properties: one series LLC filing fee covers multiple properties, each protected from the others' liabilities. However, series LLCs are not recognized in all states, which creates complications if you operate across state lines, and their liability protection has not been tested as thoroughly in court as traditional LLC structures.
