San Antonio Companies and Their Returns
San Antonio's private sector grew up around the military bases and still leans on them, but it now also includes a large health care industry, auto manufacturing on the South Side, financial services, cybersecurity firms and a tourism trade centred on the Alamo and the River Walk. Each brings different federal tax issues, and all of them file the Texas franchise tax report and Public Information Report, because Texas has no corporate income tax to replace it. BOMCAS prepares federal business returns and franchise tax reports for San Antonio companies remotely.
Our Texas business tax page explains margin methods and due dates; this page applies them to San Antonio contractors, suppliers and hospitality groups.
Defense, Cyber and Government Contractors
Firms that serve Joint Base San Antonio, the Air Force's cyber and intelligence units at Lackland, Brooke Army Medical Center or Port San Antonio work under federal contracts with their own accounting rules. Cost-plus and time-and-materials contracts require unallowable costs to be kept apart, indirect rates to be supported and timekeeping to be exact. On the tax side, these companies often have research costs, which federal law again allows to be deducted in the year paid for domestic research beginning in 2025, and many qualify for the research credit. Small contractors can also use part of the credit against payroll tax.
Toyota Suppliers and Manufacturers
The Toyota truck plant on the South Side is surrounded by suppliers, several of them on the plant site itself, and other manufacturers work in the industrial parks along Loop 410 and Interstate 35. Their returns depend on inventory and overhead costing, tooling paid for by customers, and depreciation on presses, robots and conveyors. Customer-funded tooling needs a clear agreement on who owns it, because that decides who depreciates it.
Hospitality and Tourism Groups
Hotel owners, restaurant groups, tour operators and event companies downtown and along the River Walk have seasonal cash flow, heavy payroll and large lease commitments. Many operate several locations through separate LLCs, which raises questions about combined franchise tax reporting and about how management fees and shared staff costs are charged between them. We look at the group structure as a whole.
Medical Practices and Health Services
The South Texas Medical Center in the northwest of the city holds hospitals, UT Health San Antonio, clinics and many private practices, and home health and therapy companies serve the wider region. For franchise tax, most choose the compensation deduction or 70 percent of revenue. Federal returns involve equipment, practice loans and the limits on the qualified business income deduction for specified service businesses.
Eagle Ford Service Companies
South and east of the city, the Eagle Ford Shale supports trucking, water hauling, sand, equipment rental and well service businesses based in San Antonio. Like oilfield firms elsewhere, they face swings in revenue, heavy equipment purchases and the question of how much depreciation to take in a good year. Revenue that is passed through to royalty or working interest owners may be excluded from franchise tax revenue when the rules are met.

San Antonio Business Tax Preparation Questions
Do San Antonio defense contractors get special tax treatment?
Not a separate tax regime, but government contract accounting affects how costs are recorded, and many qualify for research cost deductions and credits.
Who depreciates tooling a customer paid for?
Generally the owner of the tooling under the contract. The agreement needs to say clearly who owns it.
Do several restaurant LLCs file one franchise tax report?
Related entities under common control may have to file as a combined group. We review ownership to decide.
Is there a corporate income tax in Texas?
No. The franchise tax applies instead, and the federal return is still required.

Returns depend on contract and inventory bookkeeping, payroll under federal wage rules and current sales and hotel tax. Owners report K-1s on personal returns, growth calls for planning, lapsed LLCs need catch-up filing, and Canadian suppliers should read cross-border tax. The same subjects across the state are covered on our Texas pages for personal returns, sales tax, bookkeeping, payroll, planning, late filing and cross-border work, with a summary in the statewide overview.
