To start a sole proprietorship in Texas, you don’t file anything with the state to create the business itself — it forms automatically the moment you begin operating for profit.1Office of the Texas Secretary of State. Selecting a Business Structure The work is in the steps around it: filing an assumed name certificate if you’ll use a business name, getting an EIN and sales tax permit where they apply, checking for industry permits, and setting up your taxes and records correctly from day one.
What a Sole Proprietorship Is in Texas
The law treats you and your business as the same legal entity. You personally own every asset the business uses, and you personally owe every debt and obligation it takes on. There is no corporate shield. That’s why insurance and clean recordkeeping matter more for sole proprietors than the light setup process suggests.
File an Assumed Name Certificate (DBA) If You’ll Use a Business Name
If you plan to operate under any name that doesn’t include your legal surname, Texas requires you to file an Assumed Name Certificate with the county clerk in every county where you keep a business location or conduct business.2State of Texas. Texas Business and Commerce Code Chapter 71 – Assumed Business or Professional Name This filing is commonly called a DBA. If you’re operating under your own full legal name, no filing is required.
The certificate asks for your full legal name, your address, the assumed business name, the business address, and how long you plan to use the name. The maximum term is ten years from the filing date, and you can pick a shorter one.3Office of the Texas Secretary of State. Form 503 – Assumed Name Certificate You have to sign in front of a county clerk deputy or a notary before submitting.4Parker County, TX. Assumed Name Certificate (DBA)
Fees vary by county. As examples, Travis County charges $23 for one owner plus $0.50 for each additional owner on the same certificate,5Travis County Clerk. DBAs and Parker County charges a flat $25.4Parker County, TX. Assumed Name Certificate (DBA) Texas caps notary fees at $10 for the first signature and $1 for each additional one.6Office of the Texas Secretary of State. Notary Public Educational Information Walk-in filings are usually processed the same day; mailed applications must be notarized first and take longer.
Before you file, search your county clerk’s records and the U.S. Patent and Trademark Office database to confirm the name isn’t already in use.
Get an EIN from the IRS
An Employer Identification Number is a nine-digit identifier issued by the IRS. You must have one if you hire employees, operate a retirement plan, or file certain excise tax returns.7Internal Revenue Service. Get an Employer Identification Number Even when none of that applies, many sole proprietors get one anyway to keep their Social Security number off contracts, vendor forms, and bank paperwork. The online application is free and issues your EIN immediately.
Apply for a Sales Tax Permit If You Sell Taxable Goods or Services
If you’ll sell taxable goods or provide taxable services, you need a Sales Tax Permit from the Texas Comptroller of Public Accounts before your first sale.8Texas Comptroller of Public Accounts. Sales Tax Permit Requirements There’s no fee, though the Comptroller can require a security bond in some cases.9Texas Comptroller of Public Accounts. Sales and Use Tax Frequently Asked Questions
Apply online through the Comptroller’s WebFile system. The application asks for your business type, address, start date for sales, and a NAICS code describing your trade. Allow two to three weeks for the physical permit to arrive by mail.10Texas Comptroller of Public Accounts. Texas Online Tax Registration Application You’re required to display it at your place of business.
Check for Industry and Local Permits
Texas does not require a general business license, but plenty of industries and local governments do impose their own requirements.11Office of the Texas Governor. Start a Business in Texas Depending on your work and location, you may need:
- Zoning clearance confirming your business activity is allowed at your location
- A home occupation permit if you’ll operate from your residence, required in many cities
- A health department permit for food service, childcare, and similar operations
- A professional license from the Texas Department of Licensing and Regulation for occupations such as electrical work, barbering, cosmetology, and property inspection
Operating without a required permit can lead to fines or forced closure. The Governor’s office publishes a Texas Business Licenses and Permits Guide for state-level requirements, and your city or county clerk can point you to local ones.
Separate Your Business Banking
Texas doesn’t require sole proprietors to keep a separate business bank account, but doing so makes tax preparation easier and reduces audit risk. Mixed personal and business transactions make it harder to prove which expenses were legitimate deductions.12U.S. Small Business Administration. Open a Business Bank Account Most banks want your EIN (or Social Security number if you don’t have one), a copy of your Assumed Name Certificate, and a government-issued photo ID. Some also ask for an industry license.
Handle Federal Taxes
Sole proprietors report business income and expenses on Schedule C, filed with your personal Form 1040.13Internal Revenue Service. About Schedule C (Form 1040), Profit or Loss From Business (Sole Proprietorship) Your net profit flows onto your personal return and is subject to regular income tax.
Self-Employment Tax
On top of income tax, you owe self-employment tax to cover Social Security and Medicare. For 2026 the combined rate is 15.3 percent: 12.4 percent for Social Security on net earnings up to $184,500, and 2.9 percent for Medicare on all net earnings.14Social Security Administration. 2026 Cost-of-Living Adjustment (COLA) Fact Sheet Net earnings over $200,000 ($250,000 for married filing jointly) trigger an additional 0.9 percent Medicare surtax. You owe self-employment tax only if your net earnings from self-employment reach at least $400 for the year.
Quarterly Estimated Payments
Because no employer withholds tax from your business income, you’re generally expected to send quarterly estimated payments to the IRS. For the 2026 tax year the deadlines are April 15, 2026; June 15, 2026; September 15, 2026; and January 15, 2027. Missing them can trigger underpayment penalties even if you pay in full at filing.15Internal Revenue Service. Publication 509, Tax Calendars
What You Don’t Owe: Franchise Tax and BOI
Texas has no personal income tax, so there’s no state income return. The state does levy a franchise tax on many business entities, but sole proprietorships are explicitly exempt and don’t file a franchise tax report.16Texas Comptroller of Public Accounts. Franchise Tax Overview
You also don’t have a Beneficial Ownership Information report to file. The Corporate Transparency Act originally required many small businesses to file BOI reports with FinCEN, but under an interim final rule published in March 2025, all domestic entities are exempt.17Financial Crimes Enforcement Network. BOI Small Entity Compliance Guide A Texas sole proprietorship, even one with a registered DBA, is a domestic entity and doesn’t need to file.
Keep Records That Support Your Return
Every legitimate business expense you can document lowers your taxable profit on Schedule C. The IRS expects you to keep receipts, invoices, bank statements, and canceled checks that support the income and deductions you report.18Internal Revenue Service. What Kind of Records Should I Keep
Typical deductions include office supplies, business travel, advertising, software subscriptions, and vehicle mileage. The 2026 IRS standard mileage rate for business driving is 72.5 cents per mile.19Internal Revenue Service. 2026 Standard Mileage Rates Keep employment-related records at least four years. For most other business records, the IRS recommends at least three years from the date you file, longer if you report losses or hold depreciable assets.
Protect Yourself with Insurance
Because a sole proprietorship provides no separation between business debts and personal finances, one lawsuit or serious accident can reach your home, savings, and other personal property. Insurance doesn’t remove that legal exposure, but it puts money between you and a claim.
A general liability policy covers common third-party claims like bodily injury and property damage tied to your operations. If you sell professional advice or services, errors and omissions insurance (also called professional liability) covers claims that your work was inadequate or caused a client financial harm. That coverage is especially relevant for consultants, accountants, IT professionals, contractors, and real estate agents. Neither policy is legally required for most Texas sole proprietors, but the premium is generally far less than the cost of defending a single lawsuit.
