DIY vs. a Formation Service
The Real Cost of Filing Your Own LLC: What You Save and What You Risk (2026)
The reason do-it-yourself LLC formation looks cheap is that only one number is visible at the start: the state filing fee. Pay it, submit the paperwork, and the business legally exists. What that single number hides is everything that comes after it, the fees that repeat every year, the deadlines that trigger penalties when missed, and the hours a first-time owner spends learning a process they will run exactly once. The true cost of forming an LLC is not the price on the checkout screen. It is that price plus the ongoing obligations plus the risk of getting a step wrong.

Get Started with ZenBusiness →Plenty of people form a clean, compliant LLC on their own and never look back. The catch is that the savings are usually smaller than the sticker prices suggest, because the state fee is the one cost neither path avoids. This article lays out what each path costs, using current figures from state business agencies, the IRS, and FinCEN, and shows where the real savings are and where they quietly disappear. Fees vary widely by state and change over time, so treat every figure here as a range or an example, and confirm the exact number with your state's official source before you file.
What does it actually cost to form an LLC on your own?
The only truly unavoidable cost of forming an LLC yourself is the state filing fee for your Articles of Organization (called a Certificate of Organization or Certificate of Formation in some states), which runs from about $35 to $500 depending on where you file. Montana sits at the low end near $35, Massachusetts at the high end near $500, and the national median is roughly $100. That fee is the same whether you file it yourself or a service files it for you. No one avoids the state fee.
Beyond that first filing, the recurring and situational costs are what most new owners underestimate:
- ✓The ongoing report. Most states require an annual or biennial report to keep the LLC in good standing, with fees ranging from $0 to $500 or more. A handful of states (including Arizona, Mississippi, Missouri, New Mexico, Ohio, and South Carolina) do not require a periodic report at all, while others charge every year on a fixed date or your formation anniversary.
- ✓A franchise or business tax. A small number of states charge a franchise or privilege tax simply for the LLC existing, regardless of income. California is the well-known example at an $800 minimum per year, owed even in a year with zero revenue. Most states have no such tax, but if yours does, it usually dwarfs the filing fee over time.
- ✓The registered agent. Every state requires a registered agent (in some states called a registered office or an agent for service of process) with a physical in-state street address available during business hours. You can serve as your own for $0 if you have a qualifying address, or hire a service for roughly $39 to $299 per year.
- ✓The EIN. A federal Employer Identification Number is free directly from the IRS. It costs nothing when you apply yourself at IRS.gov.
- ✓Situational extras. Optional name reservation, expedited processing, and certified copies each carry their own fees. A few states also require you to publish notice of your formation in a newspaper, which can add anywhere from a modest amount to several hundred dollars depending on the county.
For a straightforward single-member LLC where the owner serves as their own registered agent, the pure cash cost of the do-it-yourself path in year one is often just the state filing fee, with the report fee due later. That is a real and modest number. It is also not the whole number, because it counts only dollars and none of the time or risk.
How much more does a formation service like ZenBusiness cost than filing yourself?
Less than most people assume at the entry level, and sometimes nothing at all for the filing itself. ZenBusiness is an LLC formation and compliance platform that prepares and files your formation documents, can serve as your registered agent, sends deadline alerts for annual reports and other compliance items, can obtain your EIN, and provides operating-agreement templates. Its pricing is tiered, and the entry tier adds no service fee on top of the state cost.
Based on ZenBusiness's published pricing at the time of writing, the posture looks like this:
- ✓Starter: $0 plus your state filing fee. It includes a business name search, preparation and filing of your formation documents, a 100% accuracy guarantee, a document dashboard, and compliance alerts. It does not include registered agent service or an EIN.
- ✓Pro: about $199 per year plus state fees. It adds faster (one-business-day) internal processing, an EIN, an operating agreement template, and ongoing compliance filings.
- ✓Premium: about $299 per year plus state fees. It adds unlimited compliance amendments and a business advisor consultation.
Registered agent service is not part of any tier. It is sold on its own for about $199 per year, or $99 for the first year when you add it at formation. Prices and package contents change, so confirm the current numbers on the ZenBusiness site rather than relying on a figure in any article, including this one.
The answer to "how much more" is therefore a range, not a single number. At the Starter tier, a service can cost the same as filing yourself, because you still pay only your state fee. Where a service costs more is at the paid tiers, where you are buying speed, bundled documents, and someone tracking your deadlines, with a registered agent as a separate add-on if you want one. One thing worth flagging: many formation checkouts, ZenBusiness included, offer a paid EIN add-on for around $99. Skip it. The IRS issues EINs for free, and paying for one is paying for a step the government does not charge for.
So how much do you really save by filing it yourself?
The money you save by filing yourself is the service fee you avoid, which at the entry level can be $0 and at the paid tiers is roughly $199 to $299 per year. That is the entire cash difference. Every other cost, the state filing fee, the annual report, the registered agent if you pay for one, and the EIN, is either identical on both paths or free on both paths. This is the part that surprises people: the savings from going it alone are not the gap between a small state fee and some large service bill. They are the gap between the state fee and the state fee, unless you choose to buy a higher tier.
Here is the side-by-side.
| Cost item | Filing it yourself | Using a formation service |
|---|---|---|
| State filing fee (Articles of Organization) | $35 to $500, one time, set by your state | Same state fee; you pay it either way |
| Service fee | $0 | $0 at the entry tier; about $199 to $299/yr at paid tiers |
| Registered agent | $0 as your own with an in-state address; about $39 to $299/yr for a service | About $199/yr as a separate add-on ($99 the first year when added at formation) |
| Annual / biennial report | $0 to $500+ by state, plus your time to track and file it | Same state fee, tracked and filed for you on compliance tiers |
| Franchise / business tax | None in most states; up to $800/yr in states like California, regardless of income | Same (a service files, it does not lower the tax) |
| EIN | $0 from the IRS | $0 from the IRS, or bundled in higher tiers |
| Operating agreement | $0 if you draft or template it yourself | Template included in higher tiers |
| Potential penalty exposure | Late fees (up to $400 in some states) and administrative dissolution if a deadline slips | Reduced by deadline alerts and compliance filing |
Once the cash comparison is this close, the real question shifts from price to what your time and your risk tolerance are worth. That is the heart of the choice between doing it yourself versus a service, and it is where the hidden costs live. The easy-to-miss ones include:
- ✓Your time to learn the process once. Reading state instructions, completing the Articles correctly, meeting the registered agent rule, and applying for the EIN in the right order adds up to several hours for a first-timer.
- ✓The tracking burden. Nothing reminds a solo filer that a report is due. States mail notices, but most also state that not receiving the notice does not excuse a late filing.
- ✓The cost of a wrong turn. A rejected filing, a misspelled name, or an EIN applied for at the wrong moment can each cost a re-file, a fee, or a delay.
- ✓The value of a paper trail. A dashboard that stores your formation documents, EIN letter, and filed reports is worth something the first time a bank or landlord asks for them.
What tends to go wrong when you file alone, and what it costs to fix?
The expensive mistakes in do-it-yourself formation are rarely the filing fee. They are the compliance steps that come after, and the fixes usually cost more in time than in money. These are the risks of filing yourself that first-time owners run into most often.
Registered agent errors. Every state requires a real, staffed in-state address to receive legal documents. Listing an address you do not reliably monitor, or missing service of process because no one was there to receive it, can mean a lawsuit proceeds without your knowledge. Using your home address also puts it on the public record.
Missed ongoing deadlines. The annual or biennial report is the classic miss, and the first one is the one people forget most, because it typically comes due about a year after formation when the business is busy and the owner has stopped thinking about paperwork. Consequences escalate: many states charge a late fee (some as high as $400), and continued non-filing leads to administrative dissolution, which can strip the liability protection that was the whole point of forming the LLC. Reinstatement is a separate process that costs more than the missed reports would have.
The EIN step. Get the EIN free, directly from the IRS, and get the sequence right. The IRS instructs you to form the entity with your state before you apply, so applying before the state approves the LLC can delay or complicate the application. The responsible party must be a natural person, not a company, and their name and taxpayer ID must match Social Security Administration records exactly. Choosing a tax classification you did not intend can mean extra paperwork later to change it. And avoid any third-party site that charges an "EIN filing" fee for something the IRS provides at no cost.
The Beneficial Ownership Information (BOI) misconception. This one has flipped, so older advice online is now wrong. Under a FinCEN final rule effective August 14, 2026, entities formed in the United States, including most domestic LLCs, are exempt from filing a Beneficial Ownership Information report. The requirement now applies only to foreign-formed entities registered to do business in the country. The common do-it-yourself mistake in 2026 is assuming you owe a BOI filing, or paying someone to file one, when current FinCEN guidance does not require it for a domestic LLC. Check FinCEN's current guidance directly rather than trusting a dated article or a service that markets the filing.
No operating agreement. Most states do not require an LLC to have an operating agreement, so many owners skip it. That is a quiet risk. Without one, state default rules decide disputes over money, management, and what happens when a member leaves, and the absence of the document can weaken the separation between owner and business that courts look for when deciding whether liability protection holds. It matters even for a single-member LLC, precisely because a solo owner has the hardest time proving the business is a separate entity.
Fixing mistakes. The cost of an error depends on when it is caught. A rejected filing is corrected and resubmitted, but the state filing fee is often nonrefundable, so an error can mean paying twice. An error discovered after approval, such as a misspelled name or a wrong address, is not a quick edit. It requires filing Articles of Amendment, a separate document with its own fee. And a lapse in good standing can block a certificate of good standing, the document that lenders, landlords, and some clients require before they will do business with you. Caught early, these fixes are cheap. Caught late, they are expensive mainly in the delay they cause when you need the paperwork most.
The value verdict: when paying for a service is the better buy
For a first-time owner, the case for a service is not that it is cheaper, because at the entry tier it costs the same as filing yourself. The case is that the small, easy-to-miss obligations are the ones that carry the real penalties, and those are exactly what a service is built to handle. Formation is a one-time event most people can complete alone. Compliance is a repeating obligation with a deadline, and a missed deadline can put an LLC on the path to administrative dissolution. Paying a modest yearly fee to have the report tracked and filed, a registered agent maintained, and formation documents stored in one place is buying down that risk.
ZenBusiness is a reasonable example of how that value is structured, because it separates the two decisions. The formation filing is available at $0 plus the state fee, so the entry point costs the same as the do-it-yourself route, and the paid tiers add the EIN, the operating agreement template, and the ongoing compliance filings that address the failure points above, with the registered agent available as a separate add-on. Every filing is backed by an accuracy guarantee, though that guarantee covers the filing itself and does not remove the owner's underlying legal obligations. A service files on your behalf and helps you stay compliant. It does not make you exempt from the rules.
If your budget is tight and you are organized enough to track your own deadlines, filing yourself and paying only your state fee is a defensible choice. If your time is scarce, or the thought of forgetting a report keeps you up at night, or you simply want the compliance tracking off your plate, using an LLC formation service is usually the better value, and often costs nothing more than the state fee to get started. Whichever path you choose, verify every fee and deadline against the official source before you file, because the numbers move.
