Accounting & Tax Services in Richardson, TX

Richardson’s Telecom Corridor, now rebranded as the Innovation Quarter, is home to more than 5,700 companies including 600 technology firms. Major players like AT&T, Ericsson, Samsung, Fujitsu, and Texas Instruments anchor a technology ecosystem that accounts for over 130,000 jobs and 25 million square feet of office space. With UT Dallas driving research and startup incubation, tech employment in Richardson grew 97% from 2018 to 2023, making it one of the fastest-growing innovation hubs in the Southwest.

Texas franchise tax (margin tax) affects most Richardson businesses with revenue over $2.47 million, and technology companies face additional complexity with R&D tax credits, capitalized software development costs, and equity compensation for founders and employees. SaaS companies managing subscription revenue need proper revenue recognition, while startups preparing for venture capital funding require investor-ready financial statements and clean cap table accounting. Richardson’s biotech cluster around UT Dallas adds grant accounting and clinical trial compliance needs.

SDO CPA works with Richardson business owners across technology, telecommunications, and financial services to structure entities, optimize S-Corp reasonable compensation, and manage the interplay between federal tax obligations and Texas franchise tax. For businesses in the Innovation Quarter or along the Central Expressway corridor, we provide monthly bookkeeping and fractional CFO services scaled to your stage of growth.

Texas Tax Planning Tip

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

Richardson is home to over 12,000 small businesses and a population of 121,323. From Technology, Telecommunications, Financial Services to professional services, Richardson business owners need CPAs who understand R&D tax credit documentation, equity compensation planning, and SaaS revenue recognition and can provide year-round tax planning — not just compliance.
