Filing a Texas LLC Yourself vs. Hiring a Service: The Real 2026 Cost, From State Fee to Franchise Tax

Is it cheaper to file a Texas LLC yourself or hire a service?

Filing a Texas LLC yourself is cheaper on day one, because the only mandatory payment is the $300 Secretary of State fee for the Certificate of Formation (Form 205). Over the life of the business, the gap is smaller than it looks, because the true cost also includes a registered agent, the annual May 15 filings with the Texas Comptroller, the penalties that follow a missed deadline, and the hours spent getting each step right.

That is the core of the do-it-yourself (DIY) math. The state fee is the one number everyone sees. The ongoing obligations, and the cost of fixing errors, are the numbers that show up later.

One practical update matters for anyone reading older guides. For years, Texas owners filed Form 205 online through SOSDirect. On September 29, 2026, the Secretary of State launched SOSPortal, which replaced both SOSDirect and SOSUpload. The form and the $300 fee are the same, but filers now need an SOSPortal account, and client accounts from the old system did not carry over.

This guide lays out what each path actually costs in 2026, using official state and federal figures where they exist, and shows where a formation service earns its fee for a first-time owner.

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

A formation service charges its own fee on top of the $300 state fee, and in exchange it prepares and files your paperwork, tracks deadlines, and offers add-ons such as a registered agent, an EIN, and an operating agreement template. Pricing usually runs in tiers, from a no-fee basic filing to annual packages that bundle ongoing compliance.

ZenBusiness is a useful example because its pricing is published. As listed on its formation plans page at the time of writing:

• ▸Starter: $0 plus state fees, one-time. Includes a name availability search, preparation and filing of the formation documents, a 100% accuracy guarantee, compliance alerts, and a free first year of its Worry-Free Compliance service (which renews at $199 a year if kept). Standard processing is 7 to 10 business days, with a $79 rush option.
• ▸Pro: $199 plus state fees, renewing at $199 a year. Adds 1-day processing, an EIN, an operating agreement template, and ongoing compliance filing support, including up to two amendment filings a year.
• ▸Premium: $299 plus state fees, renewing at $299 a year. Adds Advanced Compliance Protection (monitoring, unlimited amendment filings, a good standing certificate, and money back on fees for missed events), plus a domain, business email, and a document library.
• ▸Registered agent service: $199 a year as an add-on to any package, or $99 for the first year when added at formation. It is not bundled into any tier.

Two points keep this in perspective. First, the processing times above reflect the service's preparation time, and the Secretary of State's own processing time is separate and varies. Second, a service files on your behalf and helps you stay on schedule, but the legal obligations still belong to the LLC and its owners. If the information you supply is wrong, or a notice goes unanswered, the consequences still land on the business.

What can go wrong when you file a Texas LLC yourself?

Most DIY problems are not about the initial filing. They come from registered agent lapses, missed Comptroller deadlines, EIN errors, unnecessary filings, and skipped paperwork, and each one carries a price tag that rarely appears in the original budget.

What happens if your registered agent misses legal papers?

Texas requires every LLC to maintain a registered agent with a physical street address in Texas (not a P.O. box) who can receive legal papers during business hours. If you list your home and are often away, or you move without filing a change, a lawsuit or official notice can go unanswered. When an agent cannot be found, Texas law allows a plaintiff to serve the Secretary of State instead, so a business can face a default judgment without ever seeing the papers. Changing the agent or registered office later requires Form 401, which costs $15.

What happens if you miss the May 15 franchise tax deadline?

Missing May 15 starts a chain of costs. The Comptroller assesses a $50 penalty on each franchise tax report filed late, and any unpaid tax picks up a 5% penalty, rising to 10% after 30 days, plus interest. For a small LLC under the $2.65 million threshold, the bigger risk is forfeiture. If the required report, including the Public Information Report, stays unfiled, the Comptroller can forfeit the LLC's right to transact business in Texas, and the Secretary of State can later forfeit its certificate of formation. During forfeiture, the company loses access to Texas courts, and owners and managers can become personally liable for certain debts the entity incurs after the forfeiture date.

Reinstatement means filing every missing report, paying tax, penalties, and interest, obtaining a tax clearance letter (Form 05-377) from the Comptroller, and filing Form 801 with the Secretary of State for $75. The state fees are modest. The weeks of delay, the trouble proving good standing to a lender or landlord, and the liability exposure are not.

What are the common EIN mistakes?

An EIN is free from the IRS, and the online application issues the number at the end of the session. Three mistakes come up often:

• ▸Applying too early. Applying before the Secretary of State approves the LLC can tie the EIN to an entity that does not yet exist, or exists under a different name.
• ▸Naming the wrong responsible party. The IRS expects an individual who actually controls the entity, and changing it later requires Form 8822-B.
• ▸Picking a tax classification blindly. LLCs default to disregarded-entity or partnership treatment. Electing corporate or S corporation status uses Form 8832 or Form 2553, and a later change means new paperwork and timing limits.

Does a Texas LLC need to file a BOI report?

No. A domestic Texas LLC does not currently need to file a beneficial ownership information (BOI) report with FinCEN. FinCEN's final rule, effective August 14, 2026, made permanent the March 2025 exemption for entities created in the United States, and the requirement now applies only to certain foreign entities registered to do business here. The DIY mistake today is the reverse of the old one: assuming a BOI report is due, or paying a third party to file one, when current guidance does not require it. Banks may still ask for ownership details when you open an account under separate customer due diligence rules. Check FinCEN's BOI page for current guidance before acting.

Why does skipping the operating agreement cost money later?

Texas does not require an LLC to have an operating agreement, so many DIY filers skip it. Without one, the default rules of the Texas Business Organizations Code settle disputes over profits, voting, and exits. Even for a single-member LLC, a signed agreement helps document the separation between owner and business that courts look for when deciding whether to respect the liability shield, and banks may ask for one when you open a business account.

How much does it cost to fix a filing mistake?

A rejected Form 205 has to be corrected and resubmitted, which pushes back your start date, and the original fee may not come back, so check the Secretary of State's guidance before refiling. An error discovered after approval, such as a misspelled name or wrong address, generally requires a Certificate of Amendment at $150 or, for certain errors, a Certificate of Correction at $15. None of these is expensive when caught early. The real cost is the time it takes to notice, which often happens when a bank, landlord, or client asks for documents that do not match.

Ready to form your Texas LLC?

If you would rather keep the state fee as your main up-front cost and still have the filing prepared, checked, and tracked, the ZenBusiness Texas LLC formation service is a practical place to start. Compare the tiers against the table above, decide whether you need a registered agent, and mark May 15 of next year on your calendar either way.
