Accounting & Tax Services in Texas

Texas is the 2nd largest economy in the United States with a $2.4 trillion GDP, home to 54 Fortune 500 companies and over 3.1 million small businesses. The state’s zero income tax policy has driven a massive corporate relocation wave from California, New York, and Illinois, with companies like Tesla, Oracle, HP Enterprise, and Caterpillar moving their headquarters to Texas in recent years.

Texas franchise tax (margin tax) is the primary state-level business tax, applying to entities with revenue above $2.47 million. Proper planning around entity structure and computation method can significantly reduce or eliminate this obligation. Major business corridors include the Dallas-Fort Worth Metroplex for technology and defense, Houston for energy and healthcare, Austin for tech startups and government, and San Antonio for military and healthcare industries.

SDO CPA serves Texas businesses statewide from our Duncanville office, providing virtual tax preparation, bookkeeping, payroll, and fractional CFO services tailored to Texas’s unique business tax landscape. Whether you’re an S-Corp owner in Houston’s Energy Corridor or a partnership operating out of Austin’s growing tech scene, we handle multi-state compliance, reasonable compensation analysis, and franchise tax planning so you can focus on running your business.

Texas Tax Planning Tip

Texas doesn’t have a state income tax, but the Texas franchise tax (margin tax) applies to businesses with total revenue above $2.47 million. Business owners should analyze whether the E-Z Computation rate (0.331% of revenue) or the standard rate (0.75% of margin, or 0.375% for wholesale/retail) produces a lower tax bill. Many Texas businesses overpay because they default to the E-Z rate without running both calculations.

Texas is home to 3,100,000+ small businesses and a population of 30,503,000. From Technology, Energy, Healthcare to professional services, Texas business owners need CPAs who understand managing franchise tax obligations alongside federal compliance for multi-location businesses and can provide year-round tax planning — not just compliance.

Challenge

Texas businesses often face managing franchise tax obligations alongside federal compliance for multi-location businesses, making tax planning and cash flow management more complex than standard approaches allow.

We deliver monthly financial reports with actionable insights, helping you understand cash flow, profitability, and tax liability before year-end.

“After relocating our consulting firm from New York to Texas, SDO CPA handled the multi-state transition, set up our S-Corp properly, and saved us over $31,000 in combined federal and state taxes in our first year.”
