San Antonio is one of the best cities in the United States to start a business. Texas has no state income tax, a straightforward business registration process, and a local economy anchored by military and defense, healthcare, tourism, manufacturing, and a growing bioscience and tech sector. The city’s population is approaching 1.5 million, and the metro is one of the fastest-growing in the country. This step-by-step guide covers everything you need to know to start a business in San Antonio the right way.
Why San Antonio is a Strong City to Start a Business
San Antonio’s economic diversity gives entrepreneurs more runway than single-industry cities provide. Joint Base San Antonio, the largest military installation in the United States, generates consistent demand for government contracting, logistics, housing, food service, and professional services. The South Texas Medical Center employs over 35,000 people and anchors a healthcare and bioscience ecosystem that creates demand for everything from medical billing services to device manufacturing. Toyota’s San Antonio manufacturing plant drives an auto supplier network throughout the region.
Tourism is a multi-billion dollar industry built around the Riverwalk, the Alamo, and major convention business at the Henry B. González Convention Center. Rackspace, founded in San Antonio and headquartered here for decades, seeded a technology and cloud services talent base that continues to support the city’s growing tech startup ecosystem. The cost of doing business remains significantly lower than Austin, which makes San Antonio increasingly attractive to businesses priced out of or never interested in the Austin premium.
Step 1: Choose Your Business Structure
Your business structure determines your liability exposure, tax treatment, and administrative requirements. The main options for Texas business owners are:
- Sole Proprietorship: Simplest structure, no separate registration required (beyond a DBA if needed). You and the business are legally the same, which means personal liability for business debts.
- Limited Liability Company (LLC): The most popular structure for San Antonio small businesses. An LLC separates your personal assets from business liabilities and offers flexible tax treatment. Texas LLCs are formed through the Texas Secretary of State.
- Corporation (C-Corp or S-Corp): More complex and appropriate for businesses seeking outside investment or planning significant equity structures. S-Corps provide pass-through taxation with corporate liability protection.
- Partnership: Relevant for businesses with multiple owners. A formal partnership agreement is critical regardless of legal structure.
For most first-time San Antonio entrepreneurs, an LLC is the right starting structure. It’s straightforward to form, provides liability protection, and keeps options open for future tax elections as the business grows.
Step 2: Register Your Business in Texas
LLCs and corporations register with the Texas Secretary of State through the SOSDirect online portal. Filing fees for an LLC are $300. Processing is typically completed within a few business days for standard filings, or same-day for expedited processing. You will need to designate a registered agent in Texas (this can be you, an attorney, or a registered agent service).
Sole proprietors operating under a name other than their legal name must file a Doing Business As (DBA) — called an “Assumed Name” in Texas — with the Bexar County Clerk’s Office. DBA filings are also required for LLCs operating under a name different from their registered LLC name.
Step 3: Get Your Federal Employer Identification Number (EIN)
Most businesses need an EIN from the IRS, even if they have no employees. You use it for business bank accounts, tax filing, and certain licensing requirements. Apply online at IRS.gov — it takes about 10 minutes and the EIN is issued immediately.
Step 4: Open a Business Bank Account
A dedicated business checking account is essential for maintaining the liability separation that makes an LLC or corporation valuable. Using personal accounts for business transactions can expose you to “piercing the corporate veil” claims that eliminate your liability protection. San Antonio’s local banking options include outstanding choices: Frost Bank (founded in San Antonio in 1868), Broadway Bank (family-owned since 1941), Jefferson Bank, Security Service Federal Credit Union, and Randolph-Brooks Federal Credit Union all serve San Antonio businesses well. See our guide to credit unions and local banks in San Antonio for a full comparison.
Step 5: Register for Texas Taxes
Texas has no state income tax, which means no personal income tax filing on business profits for pass-through entities. You will need to register for:
- Texas Sales and Use Tax Permit: Required if you sell taxable goods or services. Register with the Texas Comptroller of Public Accounts. San Antonio’s combined sales tax rate is 8.25%.
- Texas Franchise Tax: Applies to most Texas businesses. Most small businesses fall below the $2.47 million revenue threshold and owe no franchise tax, but filing requirements still apply. The Comptroller’s office has clear guidance on filing.
Step 6: Obtain Licenses and Permits
San Antonio businesses need to comply with city, county, and state licensing requirements. Common requirements include:
- City of San Antonio Business Registration: Some business types require city permits or registrations. Check the City of San Antonio Development Services Department for your specific business type.
- Bexar County requirements: Certain businesses operating in unincorporated Bexar County have county-specific licensing and inspection requirements.
- State professional licenses: Regulated professions (contractors, electricians, plumbers, healthcare providers, real estate agents, attorneys, CPAs) require Texas state licenses through the relevant state agency.
- Health permits: Food service businesses require permits from Metro Health (the San Antonio Metropolitan Health District) and must pass health inspections.
- Signage permits: Outdoor signage on commercial property requires permits from the City of San Antonio Development Services Department.
Step 7: Set Up Your Business Operations
With legal structure and compliance in place, focus on the operational foundations:
- Business insurance: General liability is the baseline. Add professional liability (E&O), commercial auto, and workers’ compensation as your business requires. For government contractors, confirm what coverage your contracts require. San Antonio employers can also review hiring and unemployment insurance obligations through the Texas Workforce Commission.
- Accounting system: Set up accounting software (QuickBooks, FreshBooks, Wave) from day one. Clean books make tax preparation, loan applications, and future business sale all substantially easier.
- Professional relationships: Engage a CPA familiar with your industry before you need one. See our San Antonio tax and financial services guide for guidance on finding the right advisor.
Step 8: Access San Antonio Business Resources
San Antonio has strong startup support infrastructure. The UTSA Small Business Development Center provides free consulting for new businesses, including business plan review, financial projections, and loan packaging. The SCORE San Antonio chapter offers free mentorship from retired executives. The San Antonio Chamber of Commerce provides networking, advocacy, and visibility. For tech and innovation businesses, Geekdom is the center of the startup ecosystem, and Tech Bloc advocates for the technology sector’s interests in city policy.
