The True Price of DIY LLC Formation in 2026: Where Your Money and Time Actually Go

Is filing an LLC yourself actually cheaper than using a service?

Filing an LLC yourself is cheaper only by the amount of the service fee, because the state filing fee is identical whether the owner files or a service files on the owner's behalf. In 2026, that state fee runs from $35 in Montana to $500 in Massachusetts, and it is only the first of several costs an LLC carries for as long as it exists.

The visible price of a do-it-yourself LLC is one government fee. The full price adds recurring state reports or taxes, a registered agent, the hours spent learning each form, and the penalties that follow a missed deadline. Formation services such as ZenBusiness charge for handling those pieces, and some entry plans cost nothing beyond the state fee. This guide lays out what each path costs using official state, IRS, and FinCEN figures, so the comparison rests on numbers rather than assumptions. Fees change often, so confirm every figure with the official source before filing.

What are the ongoing costs of running a DIY LLC?

The ongoing costs of a DIY LLC are the state's recurring report or tax, a registered agent, and any business license renewals, and they continue every year the LLC exists. These are the costs most often left out of a "cheapest way to form an LLC" calculation.

Annual and biennial reports are the most common recurring cost. Montana's annual report carries a $20 standard fee and is due by April 15, and the state has waived that fee for on-time filings through 2027, while late filings cost $35. Massachusetts sits at the other end, charging $500 every year, due on or before the anniversary of the LLC's original Certificate of Organization. New York requires a biennial statement every two years with a $9 fee.

Some states levy a tax instead of, or alongside, a report fee. Delaware LLCs do not file an annual report but must pay a flat annual tax to the Division of Corporations on or before June 1. Texas LLCs at or below the $2.65 million no-tax-due revenue threshold owe no franchise tax on 2026 reports, but they must still file a Public Information Report (Form 05-102) with the Texas Comptroller of Public Accounts by May 15.

A registered agent is the third recurring piece. 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 service of process and official notices. Owners can serve as their own agent at no cost if they have a qualifying in-state address and are reliably present during business hours. Commercial registered agents commonly charge somewhere around $100 to $300 a year, depending on the provider and the state.

Easy-to-miss costs of filing yourself

• Time. Researching state forms, tax classification, and deadlines usually takes several hours up front and recurring attention every year after.
• Privacy. Listing a home address as the registered agent or principal office address puts it on the public record in most states.
• Availability. Serving as your own registered agent means someone must be at that address during business hours, every business day, to receive legal papers.
• The first annual report. It typically comes due about a year after formation, before most owners have built a compliance routine, which is why it is the deadline new owners miss most.
• Rejected filings. State filing fees are often nonrefundable, so a rejected application can mean paying the fee again.
• Amendments. Correcting a misspelled name or wrong address after approval requires Articles of Amendment, a separate filing with its own fee.
• Misleading solicitations. Official-looking mailers charge for filings that are free, optional, or not owed at all.

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

At its October 2026 list prices, ZenBusiness costs between $0 and $299 more than filing yourself in the first year, plus the registered agent service if the owner also buys it ($99 for the first year when added at formation, then $199 a year). The state filing fee is the same on both paths, so the entire difference is the package and any add-ons.

In practice, Starter adds nothing to the formation filing itself, Pro adds $199, and Premium adds $299, with $99 more for a registered agent added at formation ($199 a year after that). After the first year, the recurring difference is the renewal ($199 for Starter's compliance service or Pro, $299 for Premium) plus any registered agent fee.

What goes wrong most often when people file an LLC themselves?

The most common DIY problems are registered agent lapses, a missed first annual report, EIN mistakes, paying for a BOI filing that is no longer required, and skipping the operating agreement. Each one is inexpensive to prevent and more expensive to repair.

Registered agent errors

The registered agent receives lawsuits, subpoenas, and state notices. An owner who lists a home address and then moves, travels, or is not home during business hours can miss service of process, which can lead to a default judgment against the business or a lapse in good standing. A P.O. box does not qualify; the address must be a physical street address in the state.

Missing the first annual report

The first annual or biennial report is the deadline people miss most, because it typically arrives about a year after formation, when nothing is yet tracking it. Some states set a fixed calendar date (Montana's is April 15, and Delaware's annual LLC tax is due June 1), while others, such as Massachusetts, tie it to the formation anniversary.

EIN mistakes

The EIN is free from the IRS, and three errors cause most of the trouble: applying before the state has approved the LLC, naming the wrong responsible party (the IRS expects an individual who controls or manages the entity), and choosing a tax classification without understanding the follow-up paperwork. A single-member LLC is taxed by default as a disregarded entity and a multi-member LLC as a partnership. Electing corporate treatment uses IRS Form 8832, and S corporation status uses Form 2553. After an entity changes its classification with Form 8832, it generally cannot change again for 60 months.

Skipping the operating agreement

Many owners skip the operating agreement because most states do not require one (New York is an exception, requiring LLCs to adopt one within 90 days of filing). Without it, the state's default rules decide disputes over ownership, profits, and exits. It matters even for a single-member LLC, because a written agreement helps document the separation between owner and business that courts look for when deciding whether to respect the LLC's liability shield.

What happens if you miss the annual report?

Missing an annual report usually triggers a late fee first, then loss of good standing, and eventually administrative dissolution, which strips the LLC of its active status until it is reinstated. The exact sequence and costs depend on the state.

• Late fees. Montana adds a $15 late fee to its report fee. Delaware adds a $200 penalty plus 1.5% monthly interest to the unpaid annual LLC tax.
• Loss of good standing. Without good standing, the state will not issue a certificate of good standing, which lenders, landlords, and some clients require. Delaware LLCs that fall out of good standing also lose the ability to bring suit in Delaware courts until restored.
• Forfeiture or dissolution. Texas can forfeit an entity's right to transact business for failure to file required franchise tax reports. Massachusetts can administratively dissolve an LLC that stops filing annual reports.
• Reinstatement costs. Getting back into good standing typically means filing every missed report, paying every missed fee and penalty, and paying a separate reinstatement fee.

Is a formation service worth it for a first-time LLC owner?

For most first-time owners, a formation service is the better value, because the yearly fee is usually smaller than the cost of a single missed deadline or amendment, and it removes the deadline-tracking burden during the busiest stretch of starting a business. The case for DIY is strongest for experienced owners in low-fee states who already have a compliance routine.

ZenBusiness illustrates the range. Even its $0 Starter plan includes a first year of annual report handling, which covers the deadline people miss most, while Pro and Premium extend that support every year. No plan changes the state fees owed or the owner's legal duties; the plans change who tracks the deadlines and who prepares the paperwork.
