DIY vs. a Formation Service
The True Cost of Filing an LLC Yourself vs. Using a Formation Service (2026)
Forming an LLC by yourself looks like the cheaper option because only one number is visible up front: the state filing fee. Everything else stays out of sight until later. The recurring fees, the deadlines that carry penalties, and the hours spent learning a process you will run exactly once all sit outside that first price tag, and they are where the real cost of a do-it-yourself LLC actually lives.

Get Started with ZenBusinessThis is a line-by-line look at what each path costs in 2026, built from state fee schedules, IRS guidance, and current federal rules rather than rounded guesses. The aim is a clear, realistic comparison, so you can weigh the money you save against the risk and the work you take on. For most first-time owners, the deciding factor is not the filing fee at all. It is what happens in the twelve months after the LLC exists.
What it actually costs to form an LLC on your own
Filing on your own costs the state filing fee plus any pieces you choose to add, and that first fee varies widely by state. Based on state Secretary of State fee schedules compiled for 2026, formation fees run from about $35 (Montana) to $500 (Massachusetts), with most states landing somewhere in between. That fee is identical whether you file it yourself or a service files it for you, because it is paid to the state, not to any middleman.
If the filing were the whole job, DIY would clearly be cheapest. It is not. A functioning LLC also needs a registered agent, usually an EIN, and, in most states, an ongoing report or tax to stay in good standing. Each of those is a separate decision with its own cost, and each is simple to overlook when you are focused on the single fee the state shows you at checkout. The upfront savings from filing yourself are real, but it is narrow: you avoid a service fee, not the underlying obligations that come with owning a company.
The ongoing costs DIY filers forget to budget for
The formation fee is a one-time charge, but the costs that follow you every year matter far more over the life of the business, and they are the ones a first-time filer is most likely to leave out of the math:
- Annual or biennial report fees. Most states require a periodic report to keep the LLC active. According to 2026 state fee data, these range from $0 in states with no report requirement (such as New Mexico, Ohio, and Missouri) to $500 in Massachusetts, with a national average near $91.
- Franchise or business taxes. Some states charge a flat annual tax regardless of income. Delaware's is $300, and California's minimum franchise tax is $800 per year, owed even in a year with no revenue, according to those states' revenue agencies.
- Registered agent service. You can act as your own agent for $0 if you have a physical in-state address and are available during business hours, or you can pay a commercial service, which typically runs from about $39 to $299 per year.
- The operating agreement. Most states do not require one, so it costs nothing to skip, but skipping it carries a different kind of cost covered further below.
- Your own time. Reading your state's instructions, filing correctly, and then tracking every future deadline is unpaid work. It is a genuine cost, even though no invoice ever arrives for it.
None of these are truly optional. Skip the registered agent and the state can reject your filing. Miss the annual report and you can lose good standing. The only thing DIY removes is a service fee. The obligations stay exactly the same.
What a formation service costs and what it includes
A formation service charges a service fee on top of the same state filing fee, and that service fee can start at $0 and rise as you add more help. The state charge underneath never changes. ZenBusiness, for example, prepares and files formation documents, offers registered agent service, sends compliance and annual-report deadline alerts, can obtain an EIN, and provides operating agreement templates.
Its pricing follows a structure that is common across the industry: a starter tier at $0 plus the state filing fee, with higher tiers sold as annual subscriptions that add faster filing, an EIN, and ongoing compliance tracking. Registered agent service is a separate add-on at $199 a year, or $99 for the first year when added at formation. Exact tier prices change over time, so the figure to check at the moment you buy is the current one on the provider's own site. The shape stays consistent, though: the entry point covers the filing itself at no service charge, and you pay more only when you want the extra services bundled and the deadlines managed for you. ZenBusiness also backs its filings with an accuracy guarantee. It is worth being precise about what that means, however. The service files on your behalf and helps you stay compliant, but it does not remove your legal obligations as the owner.
At the entry level, the service fee can be as little as $0 above the state fee, so the gap is small or nonexistent for the basic filing. The cost climbs only as you add EIN filing, registered agent service, and compliance monitoring. In other words, you are paying for services performed and time saved, not for the filing itself, which costs the same on both sides.
A line-by-line cost comparison
The table below lines up the same cost items for both paths. Exact figures vary by state and change over time, so treat the ranges as a guide and confirm your own state's numbers with its Secretary of State and its revenue agency.
| Cost item | Filing it yourself (DIY) | Using a formation service |
|---|---|---|
| State filing fee (one-time) | $35 to $500, paid to the state | Same state fee, paid through the service |
| Annual or biennial report | $0 to $500 depending on state, paid to the state | Same state fee; some tiers file it for you |
| Franchise or business tax | None in most states; $300 (Delaware) to $800 (California minimum) where it applies | Same, owed to the state either way |
| Registered agent | $0 as your own agent, or about $39 to $299 per year for a service | Included in some tiers, or available as an add-on |
| EIN | Free directly from the IRS | Free from the IRS, or obtained for you (often bundled) |
| Operating agreement | $0 for a template, more if drafted by a lawyer | Template included in some tiers |
| Service or subscription fee | $0 | $0 starter tier, paid annual tiers above it |
| Potential penalty for a missed deadline | Late fees (Florida's is $400) plus reinstatement of $100 to $300 or more after dissolution | Lower risk when the service tracks deadlines |
The pattern is hard to miss. Every state fee is identical on both sides, because the state charges the same amount regardless of who submits the paperwork. The only line where DIY is genuinely cheaper is the service fee, and even there the gap at the entry level can be zero. What you trade for that saving is the risk in the bottom row and the time spread across all of the rows above it.
What it costs when a DIY filing goes wrong
The strongest case against filing alone is not the fee. It is the price of the mistakes that are easy to make when no one is checking your work or watching your calendar. A clear look at doing it yourself versus using a service shows where the money and the time actually go, because the expensive part of a DIY LLC is rarely the setup. It is the year that follows.
The most common and costly errors:
- Registered agent errors. Every state requires a registered agent with a real in-state street address who is available during business hours to receive service of process. Using a home address you are not always at, or missing a legal notice because no one was present to accept it, can let a lawsuit proceed without your knowledge. That is a small saving attached to a large downside.
- Missed ongoing deadlines. Annual and biennial reports, franchise or business taxes, and license renewals are simple to forget when nothing is tracking them. The first report is the one people miss most, because it usually comes due about a year after formation, long after the momentum of starting has faded. Penalties follow, and continued failure can lead to administrative dissolution, which strips your good standing entirely. Florida's late fee alone is $400, and reinstatement in many states runs $100 to $300 or more, according to state filing agencies.
- Paying for a free EIN. An Employer Identification Number is free directly from the IRS. Paid "EIN filing" sites charge for something the government gives away. The common DIY errors here are applying before the state has approved the LLC, naming the wrong responsible party, and choosing a tax classification without realizing that changing it later means additional paperwork.
- Assuming you owe a BOI report. This one has changed, and the change matters. Under a FinCEN final rule effective August 14, 2026, most domestic LLCs are not required to file a Beneficial Ownership Information report. FinCEN narrowed the requirement to entities formed under foreign law that register to do business in the United States, and it exempted companies previously treated as domestic reporting companies. The DIY mistake now is the reverse of the old one: assuming you still owe a BOI filing, or paying someone to file one, when current FinCEN guidance does not require it for a domestic LLC. Confirm your own situation against FinCEN's current guidance rather than an outdated article.
- Skipping the operating agreement. Because most states do not require one, many owners leave it out. That weakens the liability protection an LLC is meant to provide and lets your state's default rules settle any internal dispute. It matters even for a single-member LLC, because the agreement helps establish the separation between owner and business that courts look for when deciding whether that protection holds.
When something does go wrong, the fix carries its own price:
- A rejected filing has to be corrected and resubmitted, and the filing fee is often nonrefundable, so a single error can mean paying the state twice.
- An error found after approval, such as a misspelled company name or a wrong address, is not a quick edit. It requires Articles of Amendment, a separate filing with its own fee.
- A lapse in good standing can block a certificate of good standing, the document that lenders, landlords, and some clients ask for before they will do business with you. The fix is usually cheap when caught early. It is expensive mainly in the time it takes to notice the problem and unwind it.
So how much do you really save by filing yourself?
On the formation filing alone, the savings can be as small as a service fee of $0 at the entry level, because the state charges the same fee either way and some services do not mark up the basic filing. The savings grow only if you also handle the registered agent, the EIN, the operating agreement, and every future deadline yourself. That is the heart of it: what you are really "saving" is the price of those services, paid instead in your own time and attention.
That trade can absolutely be worth it. Someone who is comfortable reading state instructions, keeps a reliable calendar, and does not mind serving as their own registered agent can run a compliant LLC for little more than the state fees. The math turns when a deadline slips. A single missed annual report that triggers a late fee and a reinstatement can wipe out a year or two of the service fee you avoided, and the hours spent restoring good standing are hours taken away from the business itself.
For a first-time owner, that is where a service tends to earn its cost. Using ZenBusiness as the example, the value is not that it files a form you could technically file yourself. It is that a paid tier obtains the EIN correctly, a registered agent add-on ($99 for the first year when added at formation, then $199 a year) covers the agent requirement, and the service sends the deadline alerts that keep the penalties in the table above from ever happening. The accuracy guarantee and the compliance tracking are aimed at the specific, expensive mistakes a DIY filer usually discovers only after the fact, when they are costlier to fix. Weighed that way, the question stops being "which is cheaper today" and becomes "which is cheaper across the whole life of the business," and for many new owners the answer changes once the ongoing costs and risks are in view.
If tracking every fee and deadline yourself sounds like more than you want to take on, a formation service is built for exactly that job. The ZenBusiness LLC formation service files your documents, can obtain your EIN, provides a registered agent, and sends the compliance alerts that keep small mistakes from turning into expensive ones, so your time goes into the business instead of the paperwork.
