Can I File a Texas LLC Online Myself? (SOSPortal Guide)

Yes, you can file a Texas LLC online by yourself. Texas replaced SOSDirect with SOSPortal on September 29, 2026, and you file your Certificate of Formation (Form 205) there. The state filing fee is $300, plus a small payment processing fee. You do not need a lawyer, and you do not need to live in Texas to form a Texas LLC.

This guide walks through what to prepare, how the new SOSPortal flow works, what it costs, how long it takes, and what to do after approval. It is written for business owners deciding between filing on their own and using a filing service.

5 Things to Have Ready Before You File

Gather these four things before you open SOSPortal. Having them ready up front will make your filing go smoothly.

1. Compliant Business Name

Your Texas LLC name has to be distinguishable from any business already on file with the state. It also needs to end with a designator like "LLC," "L.L.C.," or "Limited Liability Company." Before you commit to a name, run a Texas business entity search to check if it is taken.

Texas offers two different name searches, and they do different jobs:

• Free search (Texas Comptroller): The Comptroller's Franchise Tax Account Status database is free and useful for a first look. It tells you whether a business name shows up in state tax records, but it does not confirm that your desired LLC or corporation name is available for registration.
• Paid search (SOSPortal, the state's official business filing system): This is the authoritative check. You create a SOSPortal account, and the system charges $1 per search.

Once you've narrowed down your options, consider running a $1 name availability search through SOSPortal before filing. Keep in mind that only the Texas Secretary of State can make the final determination on name availability. If you want to lock in your name while you prepare the rest of your paperwork, you can reserve it for 120 days by filing Form 501 for a $40 state fee. Name reservation is optional.

2. Registered Agent

Every Texas LLC must have a registered agent. This is the person or company that receives legal mail and official state notices for your business.

• Your registered agent needs to:
• Have a physical street address in Texas (a PO box alone does not qualify)
• Be available during normal business hours
• Consent to the role in writing

You can be your own registered agent if you meet the requirements. Many business owners choose a professional registered agent service so their home address stays off the public record and they do not miss important deliveries. For more context, see our guide to what a registered agent does.

3. Management Structure and Member Information

You will tell the state whether your LLC is member-managed or manager-managed:

• Member-managed: All owners share day-to-day management. This is common for small LLCs.
• Manager-managed: You appoint one or more managers (who may or may not be owners) to run the business. This fits LLCs with passive investors.

You mark your choice on Form 205. For every LLC owner, and for any appointed managers, you will need:

• Full legal name
• Mailing address

4. Business Purpose

Form 205 lets you state a general business purpose. Most LLCs use language such as, "any lawful purpose for which a limited liability company may be organized under the Texas Business Organizations Code." A broad purpose keeps your filing flexible as your business grows.

How to File Your Texas LLC Online with SOSPortal

Here is the step-by-step process for filing a Texas LLC through SOSPortal. Allow around 20 to 40 minutes to complete the online form if you have the five items from the checklist above ready. Actual completion time may vary.

Step 1: Create your SOSPortal Account

Visit the Texas Secretary of State’s SOSPortal website and select “Create Account.” Enter your email address, verify it using the code sent to your inbox, and complete your account details.

Step 2: Start a New Filing

Once you’re logged in, you’ll land on the main SOSPortal dashboard. Then click on the “business filings” option. After that, you will see the dashboard, which lists your past submissions and provides quick links to your shopping cart, drafts, and record search.

• Click “+ Start New Filing” in the top right corner.
• On the next screen, you will be asked to pick a filing type.
• Select the “Create or Register an Entity” tile, which is the option for a Certificate of Formation, and click “Next”.

Step 3: Choose Domestic and Select the LLC Entity Type

On the following screen, confirm you are forming a new Texas business.

• Select the “Domestic” option (as opposed to registering an entity already formed elsewhere).
• Then open the entity type dropdown and “choose 205 – Domestic Limited Liability Company” from the list.
• Click “Next” to move into the actual Certificate of Formation (Form 205).

Step 4: Fill Out the Certificate of Formation

This is the main part of the form, and it’s broken into several sections. Work through them in order.

a) Entity Name

Type your business name exactly as you want it on the public record, including the LLC designator. SOSPortal checks your name against existing filings as part of the review. Attach name consent, if applicable.

b) Registered Agent & Registered Office

Choose whether your registered agent is an individual or an organization. Enter the agent’s details and a physical street address in Texas. Confirm that the agent has consented to serve.

c) Governing Persons

Choose whether the limited liability company initially has managers or the limited liability company does not initially have managers. Then, enter the name and address of each initial governing person.

For a member-managed LLC, list each initial member. For a manager-managed LLC, list each initial manager. A governing person may be an individual or a legal entity, so provide the appropriate legal name and address.

d) Purpose

Enter your LLC’s business purpose. Texas generally allows LLCs to use a broad purpose statement, such as “any lawful purpose for which a limited liability company may be organized under the Texas Business Organizations Code.”

e) Add Supplemental Provisions/Information (Optional)

Include any additional provisions or information required for your LLC. You may also upload an addendum in PDF, DOCX, or TXT format. Avoid including confidential information or personal details, such as Social Security numbers, dates of birth, or driver’s license numbers, as these may result in rejection.

f) Initial Mailing Address

Enter your LLC’s initial mailing address. Texas requires this address on the Certificate of Formation for official correspondence. You can use a street address or PO box.

g) Provide Organizer Details

Select whether the organizer is an individual or an organization. Then provide the organizer’s street or mailing address, city, state, ZIP code, and country. The organizer is the person or entity responsible for submitting the LLC formation filing.

h) Effectiveness of Filing

Choose when your LLC formation becomes effective.

• Upon filing: Your LLC becomes effective when the document is filed by the Secretary of State.
• On a future date: Choose a later effective date no more than 90 days from the date of signing.
• Upon a future event: Specify the event or condition that will make the filing effective and provide the date that falls 90 days after the Certificate of Formation is signed. You must file a statement about the event with the Secretary of State within 90 days after the Certificate of Formation is filed.

i) Execution

Before you sign, make sure of three things:

• Your registered agent has actually agreed to serve in that role.
• Your LLC’s name doesn’t falsely suggest a connection to a government agency.
• You are authorized to submit this filing on the entity’s behalf.

Signing confirms all three, and knowingly submitting false information here carries legal penalties, including perjury, under Texas law, so don’t sign until you’re sure.

Enter the organizer’s details in the signature fields:

• First name
• Middle initial (if applicable)
• Last name
• Suffix (if applicable)

Step 5: Review, Sign, Pay, and Submit

Before you can submit, SOSPortal shows you a full preview of the filing. Look over everything carefully. Submitting a materially false filing can carry criminal penalties under Texas law.

• Sign the filing: The organizer electronically signs the Certificate of Formation.
• Choose checkout: Once you’ve reviewed and signed (see Execution above), you can either add the filing to your cart or go straight to checkout.
• Pay the filing fee: The standard Texas LLC filing fee is $300. Credit card payments incur a $0.25 transaction fee plus 2.25% of the total fees charged. ACH payment is also available.
• Track your submission: Save your payment confirmation and check the “My Submissions tab” for updates. Once your filing is accepted, the Texas Secretary of State will email the submitter evidence of filing.

Transparent Fee Breakdown of What It Costs

The $300 goes to the Texas Secretary of State. The fee is the same whether you file online, by mail, or in person. Online filing is the fastest option offered by the Texas Secretary of State.

Here is what filers are generally seeing on SOSPortal:

When you pay by credit or debit card in SOSPortal, the state adds a small payment processing fee to cover the cost of using the card network. The fee is a percentage of your total payment. For a plain $300 filing, it generally adds about $7 to $8. Paying by ACH bank transfer, where available, can lower this fee.

Optional State Fees Apart from Certificate of Formation

After Your Texas LLC Is Approved: Your First Checklist

Approval from the Secretary of State is a big step. There are a few more things to handle before you start running the business:

1. Get Your EIN

2. Create an operating agreement

3. Open a business bank account

4. Register with the Texas Comptroller for Franchise Tax

5. Check for local licenses and permits

Should You File Yourself or Use a Filing Service?

Both paths work. Your LLC is just as legal either way. Here is a plain comparison to help you decide.

Filing yourself fits when:

• You have the time to read Form 205 and work through the SOSPortal flow carefully
• Your business is a simple structure (one or two owners, no outside investors)
• You have a Texas street address you are comfortable listing publicly
• You want to spend as little as possible on day one

An LLC formation service often helps when:

• You want a second set of eyes to catch common errors before submission
• You prefer to keep your home address off public records (most services include a professional registered agent in some package tiers)
• You want post-formation items like your EIN, operating agreement, and compliance support handled in one place
• You value getting the paperwork and research off your plate

The right call depends on what your time is worth and how much of the process you want to run yourself. If you want to save time and ensure accuracy in the LLC online filing process, consider seeking help from experts. Swyft Filings offers basic Texas LLC formation, with you paying only the $300 state filing fee plus applicable processing fees. Paid packages add services such as a custom operating agreement, EIN application support, and more.
