What Filing an LLC Yourself Really Costs: DIY vs. a Formation Service in 2026

How much does it cost to form an LLC on your own?

Forming an LLC on your own costs the state filing fee, which ranges from about $35 to $500 depending on the state, plus any ongoing state fees after approval. The EIN is free from the IRS, and you can serve as your own registered agent at no charge if you meet your state's requirements.

Up-front costs of the DIY path

The state filing fee is the one unavoidable formation cost, and it is the same whether you file or a service files for you. A few examples show how wide the range runs:

Fees change, and some states charge more for paper filings or expedited processing. Check the state agency's current fee schedule before filing.

Beyond the filing fee, the DIY path usually adds these up-front items:

• Registered agent: $0 if you act as your own agent, or roughly $100 to $300 a year for a commercial agent.
• EIN: $0 when obtained directly from the IRS.
• Operating agreement: $0 if you draft it yourself from a template, more if an attorney prepares it.
• New York publication: New York LLCs must publish notice of formation in two newspapers within 120 days and file a Certificate of Publication with a $50 fee. Newspaper costs depend on the county and can run from a few hundred dollars to more than $1,000.

Ongoing costs after formation

An LLC is not a one-time purchase. Most states require an annual or biennial report, and some charge a franchise tax or annual LLC tax regardless of income. California's $800 minimum franchise tax is due every year, including the first year, by the 15th day of the fourth month after formation. Kentucky's annual report, by contrast, costs $15. These fees apply to every LLC, DIY or not, so they belong in any fair comparison.

The easy-to-miss costs of filing yourself

The costs that catch DIY filers are usually not fees but tasks with deadlines:

• The first annual report. It typically comes due about a year after formation, long after the excitement of launch has faded, and it is the deadline people miss most.
• Registered agent availability. Serving as your own agent means a real in-state street address and someone present during business hours to accept service of process.
• Business license renewals. City, county, and state licenses often renew on their own schedules, separate from the annual report.
• State tax registrations. Sales tax permits and payroll accounts carry their own filing calendars.
• Corrections and amendments. A rejected filing or a typo found after approval costs time and, often, a second fee.
• Your time. A simple DIY filing typically takes a few hours, and that does not include the yearly upkeep.

How much more does ZenBusiness cost than filing an LLC yourself?

ZenBusiness costs $0 more than filing yourself at the Starter level, because both paths pay only the state filing fee. The Pro package costs $199 more in the first year and $199 a year after that. A registered agent is extra on any package, at $99 for the first year and $199 a year after, in line with the $100 to $300 a year many DIY filers pay a commercial agent anyway.

The table below compares the paths line by line for a typical first-time owner.

The state fee row is the same in every column. That is the core of the comparison: a service never makes the state cheaper or more expensive. What changes is who does the work and who watches the calendar.

What does it cost when a DIY filing goes wrong?

The cost of a DIY mistake is usually small in fees and large in time, and it grows the longer the error goes unnoticed. Most errors fall into a handful of predictable categories, each with a defined fix.

What happens if your registered agent setup is wrong?

Every state requires an LLC to keep a registered agent with a physical in-state address who is available during normal business hours. Using a home address puts that address on the public record, and missing a delivery of service of process can mean missing a court deadline. A lawsuit that goes unanswered can end in a default judgment. Changing agents later usually requires a separate state filing, and some states charge a fee for it.

What happens if you miss the annual report?

Missing an annual report or state tax payment typically triggers a late fee, then loss of good standing, and eventually administrative dissolution. Delaware, for example, adds a $200 penalty plus interest when its annual LLC tax is paid after the June 1 deadline, and a Delaware LLC that is not in good standing cannot bring a lawsuit in Delaware courts. Other states set their own penalties and timelines, so check the Secretary of State's site. Reinstating a dissolved LLC generally means paying the missed fees, any penalties, and a separate reinstatement fee.

What are the most common EIN mistakes?

The EIN itself is free from the IRS, which makes paid "EIN filing" websites that charge for the same application an avoidable cost. The common errors are:

• Applying before the state approves the LLC. If the name or entity changes, the EIN record will not match.
• Naming the wrong responsible party. The IRS expects an individual who controls the entity, not a nominee.
• Choosing a tax classification without a plan. A single-member LLC defaults to a disregarded entity and a multi-member LLC to a partnership. Electing corporate or S corporation treatment later requires Form 8832 or Form 2553, each with its own timing rules.

Does a new domestic LLC need to file a BOI report?

Under current FinCEN guidance, a domestic LLC does not need to file a Beneficial Ownership Information report. FinCEN's final rule, effective August 14, 2026, permanently exempts U.S.-formed entities and keeps the reporting requirement only for certain foreign companies registered to do business in the United States.

The DIY mistake has flipped. Owners who read older articles may assume a BOI report is mandatory, or pay a third party to file one. Before paying anyone for BOI help, check FinCEN's current BOI guidance directly.

Do you need an operating agreement if your state does not require one?

An operating agreement is worth having even where the state does not require it. Most states do not mandate one, though a handful do, New York among them. Without an agreement, the state's default LLC rules settle disputes over ownership, profits, and exits. For a single-member LLC, a signed agreement helps show the separation between the owner and the business that courts look for when deciding whether to respect the LLC's liability protection.

How do you fix a filing mistake, and what does it cost?

A rejected formation filing is corrected and resubmitted, and the original filing fee is often nonrefundable. An error discovered after approval, such as a misspelled name or wrong address, requires Articles of Amendment (the form name varies by state), which is a separate filing with its own state fee. A lapse in good standing can also block a certificate of good standing, which lenders, landlords, and some clients ask for before signing. These fixes are inexpensive when caught early. The real cost is the time spent discovering and correcting them, often at an inconvenient moment such as a loan application.

Ready to form your LLC the low-stress way?

If the numbers point toward a service, start with the package that matches how much of the ongoing work you want to hand off. ZenBusiness's LLC formation service starts at $0 plus state fees, and its Pro and Premium tiers add faster filing and compliance tracking, with a registered agent available as an add-on, for owners who would rather spend their time on the business than on the paperwork.
