What It Really Costs to File an LLC Yourself in 2026: A Line-by-Line Breakdown

What does it cost to form an LLC on your own?

Forming an LLC on your own costs the state filing fee plus any optional extras, which means the up-front bill can be under $50 in the lowest-fee states and $500 or more in the most expensive ones. After formation, the recurring costs are the same no matter who filed the paperwork.

Up-front costs of the DIY path

• State filing fee. Every state charges a fee to accept the formation document, usually called Articles of Organization (some states use Certificate of Organization or Certificate of Formation). Montana's fee is $35, while Massachusetts charges a $500 base fee. Most states fall somewhere in between.
• Registered agent. Every state requires an LLC to name a registered agent with a physical street address in the state who is available during normal business hours to accept legal papers. Owners can serve as their own agent for $0 if they meet those requirements. Commercial registered agent services commonly charge roughly $100 to $300 per year.
• Employer Identification Number (EIN). The IRS issues EINs free of charge through its online application and warns taxpayers to avoid websites that charge for one.
• Operating agreement. A self-drafted agreement built from a template costs nothing. An attorney-drafted agreement costs whatever the attorney charges, which varies widely.
• Optional state extras. Name reservations, expedited processing, and certified copies each carry small state fees that vary by state.

Ongoing costs that apply every year

• Annual or biennial report fees. Some states charge a small fee or none at all, and others charge hundreds. A Massachusetts LLC, for example, pays about $500 or more for its annual report each year.
• State franchise or business taxes. Delaware LLCs owe a $300 annual tax due June 1. California LLCs owe an $800 minimum annual tax to the Franchise Tax Board, paid with Form 3522, with the first payment due by the 15th day of the fourth month after formation.
• Registered agent renewal, if a commercial agent is used.
• Business license and permit renewals, which depend on the industry, city, and county.

A service does not change any of these state and local amounts. It changes whether someone else is tracking them.

Easy-to-miss costs of filing yourself

• Time. Reading the state's instructions, completing the forms, getting the EIN, drafting an operating agreement, and returning to the state portal every year all take hours. A useful test is to multiply those hours by what the owner's time is worth in the business.
• Privacy. When owners serve as their own registered agent, the listed address typically becomes part of the public business record.
• Rejected filings. A filing rejected for a name conflict or missing information has to be corrected and resubmitted, and the original fee is often not refunded.
• Amendment fees. An error discovered after approval, such as a misspelled name or wrong address, requires a separate amendment filing with its own state fee.
• Late penalties and reinstatement fees. Missed reports and taxes carry state penalties, and reinstating a dissolved LLC typically requires paying back fees on top of a reinstatement fee.
• Paid lookalike sites. Some websites charge for services the government provides at no cost, and the EIN is the most common example.

How much money do you actually save by forming an LLC yourself?

Forming an LLC yourself saves exactly the service fee you skip, because the state fees are identical on both paths. Compared with ZenBusiness, that is $0 against the Starter plan, $199 against Pro, and $299 against Premium in the first year, plus $99 in the first year and $199 a year after that if the owner would otherwise buy ZenBusiness's registered agent service at formation.

Over several years, the gap widens with renewals:

These figures are the dollars saved by filing alone. What they leave out is the value of the owner's time and the expected cost of mistakes. If a DIY owner would pay a commercial registered agent anyway, the registered agent row shrinks to the price difference between providers. And if the owner misses a single deadline and pays a late penalty or reinstatement fee, that one mistake can wipe out a year or more of savings.

What does it cost when a DIY filing goes wrong?

Most DIY mistakes cost little to fix when caught early, and the real expense is the time that passes before anyone notices. ZenBusiness's guide to the risks of filing yourself versus hiring a service covers the formation side in more depth. The sections below focus on what each mistake costs.

What happens if your registered agent misses legal papers?

If the registered agent is unavailable when a process server arrives, or the listed address is out of date, a lawsuit can move forward without the owner knowing, and a court may enter a default judgment. States require a physical street address in the state rather than a P.O. box, and an LLC that fails to maintain a valid registered agent can fall out of good standing. Owners who travel, work at job sites, or keep irregular hours are the most exposed when acting as their own agent.

What happens if you miss the annual report?

Missing an annual report or franchise tax payment typically triggers a late fee first, then loss of good standing, and in many states eventual administrative dissolution. In Delaware, a late annual tax carries a $200 penalty plus interest, and an LLC that is not in good standing cannot get a certificate of good standing from the Division of Corporations or have the Division file documents for it. Reinstating a dissolved LLC generally requires filing every overdue report and paying the back fees, penalties, and a reinstatement fee.

The first report is the one owners miss most. In many states it comes due roughly a year after formation, long after the rush of filing has faded. Other states use a fixed calendar date, and some payments arrive sooner. A California LLC's first $800 payment, for instance, is due by the 15th day of the fourth month after formation, which can be as little as about three and a half months.

What are the most common EIN mistakes?

The EIN itself is free from the IRS, so the most avoidable mistake is paying a third-party site for it. Other common errors include:

• Applying before the state approves the LLC. The IRS directs LLC owners to form the entity with the state first and notes that applying early can delay the application.
• Naming the wrong responsible party. The IRS requires an individual who controls, manages, or directs the entity and its funds.
• Picking a tax classification without a plan. An LLC's default federal classification can be changed later, but doing so requires new filings, such as Form 2553 for S corporation status or Form 8832 for entity classification, each with its own deadlines and rules.

Does a new LLC have to file a BOI report in 2026?

Under current FinCEN guidance, LLCs formed in the United States are not required to file a Beneficial Ownership Information report. FinCEN issued a final rule on August 11, 2026, effective on its publication in the Federal Register on August 14, 2026, that made permanent its 2025 exemption for U.S. companies and U.S. persons. BOI reporting now applies only to certain entities formed under foreign law that are registered to do business in the United States.

The common DIY mistake has flipped. Instead of missing a BOI filing, owners now assume they owe one, or pay a website to file a report that current guidance does not require for a domestic LLC. Anyone unsure should check FinCEN's BOI guidance directly before paying for anything.

Does a single-member LLC need an operating agreement?

Most states do not require an operating agreement, but a single-member LLC still benefits from one because it helps document the separation between owner and business that courts look for when deciding whether to respect liability protection. Without an agreement, the state's default LLC rules govern disputes, profit splits, and what happens if a member leaves or dies. A handful of states do require one, so check the state's LLC statute.

How much does it cost to fix a filing mistake?

The cost depends on when the mistake is found:

• Before approval: a rejected filing is corrected and resubmitted. The original filing fee is often nonrefundable, so the owner may end up paying twice.
• After approval: a misspelled name, wrong address, or incorrect member information requires Articles of Amendment (or the state's equivalent), a separate filing with its own fee.
• After a lapse: an LLC that has fallen out of good standing cannot obtain a certificate of good standing, which lenders, landlords, and some clients require. Restoring good standing means filing what was missed and paying the associated penalties.

None of these fixes is expensive on its own. The cost is the delay: a loan that stalls, a lease that waits, or a contract that goes to a competitor while the paperwork gets sorted out.
