DIY vs. a Formation Service

The True Cost of Filing Your Own LLC: What DIY Really Adds Up To (2026)

Almost every guide to forming an LLC leads with the same number: the state filing fee. It is the one cost that appears on the first page of any secretary of state website, and it is the figure that makes the do-it-yourself route look nearly free. File the articles of organization, pay the fee, and the company exists. On paper, that is the entire story.

The filing fee is real, but it is also the smallest and most visible slice of what an LLC costs to start and keep alive. The larger costs arrive later, or never show up as a line item at all: the recurring state fees, the deadlines that carry penalties when missed, the setup steps people forget, and the hours spent learning a process you will run exactly once. A comparison that stops at the filing fee is comparing the wrong number. What follows is a look at what each path actually costs, start to finish, with real fees, real deadlines, and the tradeoffs stated plainly.

What does it actually cost to file an LLC yourself?

Filing an LLC yourself costs the state filing fee, which in 2026 runs from roughly $35 on the low end to about $500 on the high end depending on the state, plus whatever you spend on the ongoing obligations that follow. Filing fees range from $35 (Montana) to $500 (Massachusetts) in 2026, and that single payment is genuinely the only unavoidable up-front cost of forming the entity. If you already have a physical in-state address where you can accept legal mail during business hours, and you write your own operating agreement from a template, the true first-day cost of a DIY LLC can be just that state fee.

The problem is that the filing fee is a one-time charge, and most of what an LLC costs is recurring. Once the company exists, several other costs enter the picture, and each one is easy to overlook because nothing prompts you to pay it:

The annual or biennial report. Most states require a periodic report to keep the LLC in good standing, with fees that range from $0 (7 states) to $500. A handful of states, including New Mexico, Ohio, Missouri, Arizona, and South Carolina, require no annual report at all, while others charge a modest fee every year or every two years. The first report is the one people miss most, because it typically comes due about a year after formation, long after the excitement of starting has faded.
Franchise or privilege taxes. A minority of states charge an annual tax simply for existing, regardless of income. California charges an $800 franchise tax as a yearly minimum, and Delaware charges a $300 flat annual tax. These are separate from the report fee and separate from income tax.
A registered agent. Every state requires the LLC to name a registered agent with a real street address in the state, available during normal business hours to receive service of process. You can serve as your own agent for free, but a commercial service typically runs $50 to $150 per year if you would rather not put your home address on the public record or be tied to a desk during business hours.
An operating agreement. Most states do not require one, so it costs nothing to skip. That is exactly why it gets skipped, and why it becomes expensive later.
Your time. Reading the state's instructions, checking name availability, completing the articles correctly, applying for the federal tax ID, and calendaring every future deadline is not difficult work, but it is real work, and it is work you learn once and rarely repeat.

There is one cost that is free either way and worth flagging, because a whole industry exists to charge for it. The federal Employer Identification Number, which the LLC needs to open a business bank account and hire employees, is free directly from the IRS. Applying for an Employer Identification Number is a free service offered by the Internal Revenue Service, and the agency warns filers to beware of websites that charge for this free service. Third-party EIN-filing services typically charge $50 to $300 to submit the same form you can submit yourself in about ten minutes. Paying for an EIN is one of the most common and most avoidable DIY-adjacent mistakes.

What does a formation service cost, and what does it include?

A formation service costs the same state filing fee you would pay on your own, plus a service fee that starts at $0 for a basic filing and rises for tiers that add ongoing help. The service does not replace the state fee or the annual obligations. What it does is prepare and file the paperwork, then track the deadlines and handle the recurring pieces so they do not depend on your memory.

ZenBusiness is a useful reference point here because its pricing follows the pattern common across the industry. ZenBusiness currently offers three formation plans: Starter, Pro, and Premium. The Starter plan has a $0 service fee, while the paid tiers add services for an annual fee, with state filing fees always charged separately. The entry tier covers the formation filing itself at no service charge, and the higher tiers layer on faster processing, an EIN, an operating agreement template, and ongoing compliance tracking. Registered agent service is a separate add-on on any plan. Exact prices change, so the current site is the place to confirm any figure, but the posture is consistent: a free filing tier, and paid tiers in the low-to-mid hundreds of dollars per year that bundle the work you would otherwise track yourself.

Beyond the filing, a service like this prepares and submits your articles of organization, offers registered agent service, sends alerts for compliance and annual-report deadlines, can obtain your EIN, and provides operating-agreement templates. ZenBusiness backs its filings with a 100% accuracy guarantee. It is worth being precise about what that guarantee does and does not mean: the service files on the owner's behalf and helps the owner stay compliant, but it does not erase the owner's underlying legal obligations. The deadlines still exist. The service's job is to make sure you do not miss them.

How much more does a service like ZenBusiness cost than filing yourself?

At the entry level, a service like ZenBusiness costs no more than filing yourself, because the basic tier carries a $0 service fee and you still pay the same state filing fee either way. The difference only appears when you choose a paid tier, and then it is the annual service fee, commonly in the low-to-mid hundreds of dollars, in exchange for EIN filing, an operating agreement, and deadline tracking, with registered agent service added separately if you want it. So the price gap between DIY and a service is zero at the free tier and a few hundred dollars a year at the paid tiers, and the fair way to judge that gap is to look at what each column below actually buys.

Cost item	Filing it yourself	Using a formation service
State filing fee (one-time)	About $35 to $500, paid to the state	The same state fee, paid to the state
Service fee	$0	$0 at the free tier; low-to-mid hundreds per year at paid tiers
Annual or biennial report	$0 to $500 depending on state; you track and file it	The same state fee; the service tracks and can file it on paid tiers
Franchise or business tax	None in most states; roughly $300 to $800 per year in a few	The same tax; a service does not reduce or remove it
Registered agent	$0 as your own agent, or about $50 to $150 per year for a commercial agent	A separate add-on, about $199 per year ($99 the first year when added at formation)
EIN	$0 directly from the IRS	$0 from the IRS, or bundled into a paid tier
Potential penalties	Late fees, reinstatement costs, and amendment fees if something slips	Reduced risk through deadline alerts and a filing accuracy guarantee

The table makes the real comparison visible. Most of the numbers are identical in both columns, because they are state charges that no service can waive. The genuine difference is the service fee, and what that fee buys is not a cheaper LLC but a supervised one.

What does it cost when a DIY filing goes wrong?

The largest hidden cost of the DIY path is not a fee at all. It is the price of an error, and errors are easy to make when no one is checking the work or watching the calendar. Most of these problems are cheap to prevent and expensive mainly in the time it takes to catch and fix them. The common ones are worth knowing before you decide the filing fee is the whole cost.

Registered agent mistakes. Every state requires a registered agent with a real in-state street address available during business hours. Using a home address you later move away from, or missing a delivered service of process, can mean a lawsuit proceeds without your knowledge and a default judgment lands before you know a case exists.
Missed ongoing deadlines. Annual or biennial reports, franchise or business taxes, and license renewals are simple to file and simple to forget. Missing an annual report deadline can be costly: Florida charges a $400 late fee if the report is filed after the deadline, and across states, failure to file can eventually result in administrative dissolution, requiring a reinstatement filing that often runs $100 to $300 or more. Administrative dissolution means the state stops recognizing the company, which can suspend the liability protection you formed the LLC to get in the first place.
EIN errors. The federal tax ID is free, but there is a right order to get it. If you are creating an LLC, form your entity through the state before you apply for an EIN, because applying before the state approves the LLC can delay the application. Naming the wrong responsible party, or choosing a tax classification without realizing that changing it later means new paperwork, are the other frequent stumbles. And paying a third-party site for the EIN, as noted earlier, is money spent on nothing.
The BOI misconception. For years, new owners were told to file a Beneficial Ownership Information report and to watch the deadline. That guidance has changed, and assuming the old rule still applies, or paying someone to file a report you do not owe, is now the mistake. Under a FinCEN final rule that became effective August 14, 2026, the requirement to report beneficial ownership information was permanently removed for U.S. companies and U.S. persons under the Corporate Transparency Act. The rule maintains obligations only for foreign entities registered to do business in the U.S. In plain terms, a typical LLC formed under a U.S. state is not required to file a BOI report. The Corporate Transparency Act remains on the books, so the current guidance from the Financial Crimes Enforcement Network is the place to confirm your status before acting.
No operating agreement. Skipping this document is free and legal in most states, which is precisely the trap. Without one, state default rules settle any dispute, and the absence of a written owner-business separation can weaken the liability shield a court looks for. It matters even for a single-member LLC, where it helps establish that the company is genuinely separate from its owner.
Fixing what is already filed. A rejected filing gets corrected and resubmitted, and the filing fee is often nonrefundable, so a careless error can mean paying twice. An error caught after approval, such as a misspelled company name or a wrong address, requires Articles of Amendment, a separate filing with its own fee. And a lapse in good standing can block a certificate of good standing, the document lenders, landlords, and some clients ask for before they will do business with you.

None of these is rare. They are the ordinary friction of running a legal entity, and they are exactly the friction a compliance service is built to absorb. This is the heart of the tradeoff in doing it yourself versus using a service: the DIY route saves the service fee and hands you the tracking, the deadlines, and the risk of the small mistakes that get expensive when they go unnoticed.

So how much do you actually save by filing an LLC yourself?

At the moment of filing, the amount you save by going it alone is the service fee, and against a free formation tier that difference is zero. You pay the same state fee, you can get the same free EIN from the IRS, and you can write an operating agreement from a template at no cost. Judged only on the up-front bill, a careful DIY filing and a free-tier service filing land in nearly the same place. The savings that people imagine, hundreds of dollars kept in their pocket, only materialize when the comparison is against a paid tier, and even then the paid tier is buying something specific.

So the real savings question is not about the filing at all. It is whether the time you spend and the risk you carry are worth the money the paid tier would have cost. The EIN is free either way. The state fees are owed either way. What a service adds is a filed set of documents backed by an accuracy guarantee, a registered agent so your address stays private and your legal mail gets received, and an alert before every deadline so the report you would have forgotten does not turn into a late fee or an administrative dissolution. For an experienced owner who has done this before and keeps a tight calendar, the DIY savings are real and the risks are manageable. For a first-time owner, the money saved by filing alone is often smaller than the cost of a single missed deadline or a single amendment to fix a typo.

For that reason, a supervised path tends to be the better value the first time through. An LLC formation service does not make the LLC cheaper, and it should not be sold as if it does. What it does is convert a scattered set of one-time and recurring obligations into a single managed process, which is worth the most to the people most likely to miss one of them. The filing fee was never the real cost. The real cost was always the work and the risk behind it, and that is the part worth paying attention to before deciding which path to take.
