The True Cost of Filing a Texas LLC Yourself: What the $300 Fee Doesn't Show (2026)

How much does it cost to start a Texas LLC on your own?

Filing a Texas LLC yourself costs $300 in state fees at a minimum, which is the Certificate of Formation (Form 205) filing fee charged by the Texas Secretary of State. Filing online through SOSDirect adds a small convenience charge (Texas applies roughly a 2.7 percent credit card fee, which brings a $300 filing to about $308). That is the entire mandatory up-front cost if you serve as your own registered agent and prepare every document yourself. Confirm the current fee on the Secretary of State fee schedule at sos.state.tx.us, since state fees change.

So the honest headline answer is that a bare-bones Texas LLC can be formed for about $300 to $308. But "formed" is not the same as "set up to operate and stay compliant." The up-front figure leaves out several costs that are optional in theory and necessary in practice:

• •Registered agent. Texas requires every LLC to name a registered agent with a physical Texas street address who is available during business hours. You can be your own agent for $0, but that puts your address on the public record and ties you to being reachable during the day. A commercial registered agent service runs roughly $100 to $300 per year (many are near $125).
• •Operating agreement. Texas does not require one, so it is easy to skip. A template can be free, and custom drafting can run from about $50 to several hundred dollars or more. Skipping it entirely has its own cost, covered below.
• •EIN. The IRS issues an Employer Identification Number for free at irs.gov. It costs nothing when you do it yourself, but paid "EIN filing" sites charge for the same thing, so this is a place people spend money they did not need to.
• •Name reservation (optional). Reserving a name before filing costs $40 for 120 days through the Secretary of State. Most filers skip it and simply put the name on the Certificate of Formation.
• •Expedited processing (optional). Standard SOSDirect approval takes days to a couple of weeks depending on the filing method. Texas offers expedited processing for an additional per-document fee if you need it faster.

Then there are the ongoing costs, which are where a lot of DIY filers get surprised, because nothing about the first $300 hints at them:

• •Annual Public Information Report. Every Texas LLC must file a Public Information Report with the Comptroller each year. It is free to file, but it is mandatory, and the first one is due the year after formation, which is precisely why it is the report people forget.
• •Franchise tax report. Texas requires an annual franchise tax report due each May 15. Most small LLCs owe no tax, because only entities above the state's no-tax-due threshold (annualized total revenue of roughly $2.47 million, which the Comptroller adjusts, so verify at comptroller.texas.gov) actually pay. Below that threshold there is no tax owed, but the required report still has to be filed.
• •Registered agent renewal. If you hired a commercial agent, that fee recurs every year.
• •Licenses and permits. Depending on your industry and city or county, you may owe business license or permit renewal fees. These vary widely and are set locally.

None of this makes DIY a bad choice. It makes DIY a choice with a real total cost that is higher than $300, and with recurring obligations that no one tracks for you.

What does it actually cost when a DIY filing goes wrong?

This is the part the $300 number hides completely, and it is where the real difference between the two paths lives. The mistakes below are common, and each one carries a cost in dollars, in time, or in both.

• •Registered agent errors. Every state, Texas included, requires a registered agent with a real in-state address available during business hours. Using a home address you later move away from, or missing a service-of-process delivery because no one was there to receive it, has genuine consequences. Missed legal notice can mean a default judgment you never saw coming, and a registered agent who is not reliably available can jeopardize your standing with the state.
• •Missed ongoing deadlines. The annual Public Information Report and the franchise tax report are easy to miss when nothing tracks them for you, and the first report, due about a year after formation, is the one people forget most. Missing the required filing risks forfeiture of your LLC's right to transact business in Texas, per the Comptroller. Forfeiture is reversible, but reinstating standing costs time and paperwork, and a lapse can surface at the worst moment.
• •The EIN step. Get your EIN free, directly from the IRS. The common errors are applying before the state has approved your LLC, naming the wrong responsible party, and choosing a tax classification without realizing that changing it later means new paperwork. And beware paid "EIN filing" sites that charge for what the IRS provides at no cost.
• •The Beneficial Ownership Information misconception. This one changed recently, and a lot of DIY filers have it wrong. Under a FinCEN final rule effective August 14, 2026, most domestic LLCs are not required to file a Beneficial Ownership Information (BOI) report. The requirement was narrowed to foreign-formed entities registered to do business in the United States. The common mistake now is assuming you owe a BOI filing, or paying a site to file one, when current guidance does not require it for a domestic LLC. Do not act on old information here; check FinCEN's current guidance at fincen.gov/boi before doing anything.
• •No operating agreement. Many owners skip it because Texas does not require one. That is a quiet risk. Without an operating agreement, state default rules settle any dispute, and the absence weakens the separation between you and your business that liability protection depends on. It matters even for a single-member LLC, because it helps establish the owner-business separation courts look for when deciding whether to respect the liability shield.
• •Fixing mistakes after the fact. A rejected filing gets corrected and resubmitted, and the state filing fee is often nonrefundable, so an error can mean paying twice. An error caught after approval, like a misspelled name or wrong address, is not a free edit; it requires filing Articles of Amendment, a separate filing with its own fee. And a lapse in good standing can block a certificate of good standing, which lenders, landlords, and some clients require before they will do business with you. The fix is cheap when you catch it early. It is expensive mainly in the time and stress it takes to catch it late.

None of these are exotic. They are the ordinary failure modes of doing an unfamiliar process once, with no one checking the work. If you weigh doing it yourself versus using a service, this list of what can go wrong is the real cost on the DIY side, and it is the one the filing fee never shows.
