Texas Single-Member LLC — Formation & Tax Guide

A single-member LLC is the most common business structure in Texas — one owner, full liability protection, and the simplest possible tax treatment. Under the Texas Business Organizations Code, a single-member LLC has the same legal protections as a multi-member LLC despite having only one owner. See all LLC types or start with our formation guide.

What Is a Single-Member LLC?

A single-member LLC (SMLLC) is a limited liability company with one owner (member). In Texas, it offers:

• Full liability protection — your personal assets are separate from the LLC's debts
• Pass-through taxation — by default, the IRS treats it as a "disregarded entity" (you report business income on your personal Schedule C)
• No separate state return — Texas has no income tax, so there is no state filing for a disregarded entity beyond the franchise tax report
• Flexibility — you can elect S-corp or C-corp tax treatment if it benefits you

Texas-Specific Considerations for Single-Member LLCs

Charging order protection: Under the Texas Business Organizations Code, a charging order is the exclusive remedy available to a creditor against a member's transferable interest, providing strong asset protection for single-member LLCs. Texas is one of the strongest states for SMLLC asset protection because the statute applies equally to single-member and multi-member LLCs.

Community property: Texas is a community property state. If you form an SMLLC using community funds (earned during marriage), your spouse may have a community property interest in the membership. This does not make it a multi-member LLC for tax purposes, but it has implications for divorce and estate planning. Consider:

• A transmutation agreement (spouse agrees the interest is separate property)
• Addressing the community property interest in your operating agreement
• Consulting a family law attorney if significant assets are involved

Operating agreement: Texas courts are more likely to pierce the veil of a single-member LLC that lacks an operating agreement. In cases like In re Waller Creek Investments (Bankr. W.D. Tex., 2017), courts looked at whether the sole member treated the LLC as a separate entity — having a written operating agreement is strong evidence of separation.

Formation Process

The formation process is identical to any Texas LLC:

1. Search for name availability on SOSDirect
2. Appoint a registered agent
3. File Certificate of Formation (Form 205) — $300
4. Create an operating agreement (yes, even as a single member)
5. Apply for EIN (free, immediate online)
6. Open a business bank account

Federal Tax Treatment

Default (disregarded entity):

• Report all LLC income/expenses on Schedule C (Form 1040)
• Pay self-employment tax (15.3%) on net profit
• No separate LLC tax return filed with the IRS
• Use your EIN for banking and contractor payments

S-corp election (Form 2553):

• Recommended when net profit consistently exceeds $60,000-$80,000
• Pay yourself a reasonable W-2 salary, take remaining profit as distribution (not subject to self-employment tax)
• Must run payroll and file Form 1120-S
• See our tax elections guide

Texas Tax Treatment

• Franchise tax: File No Tax Due report (Form 05-169) if revenue under $2.47M. Due May 15 annually.
• State income tax: None. Zero. Not applicable.
• Sales tax: Only if you sell taxable goods/services (6.25% + local). Get a permit from the Comptroller.

FAQ

Does a single-member LLC need an EIN?

Not technically required by the IRS (you can use your SSN), but strongly recommended. Banks typically require an EIN to open a business account, and using your EIN instead of your SSN on vendor forms (W-9) protects your personal identity.

Can a single-member LLC add members later?

Yes. You can admit new members at any time by amending your operating agreement. No state filing is required to add members (unless the change also affects your Certificate of Formation). Adding a member changes your federal tax classification from disregarded entity to partnership (Form 1065), which takes effect the day the new member is admitted.

Is a single-member LLC protected from lawsuits in Texas?

Yes. The LLC's liability shield protects your personal assets from the LLC's business debts and lawsuits. However, the veil can be pierced if you: commingle funds, fail to maintain the LLC as a separate entity, use the LLC to perpetrate fraud, or are personally negligent (your own actions, not the LLC's). Maintain separation and keep an operating agreement.

Should I use a single-member LLC or sole proprietorship?

Always the LLC. A sole proprietorship offers zero liability protection. The $300 Texas filing fee is trivial compared to the personal asset exposure of operating unprotected. The only downside of an SMLLC vs. sole proprietorship is the $300 formation cost and annual franchise tax report (which costs $0 to file).
