Accounting & Tax Services in Tempe, AZ

Tempe serves as metro Phoenix’s innovation and startup hub, with over 15,600 businesses concentrated around Arizona State University, the Tempe Town Lake district, and the South Tempe technology corridor. ASU’s presence creates a vibrant ecosystem of research spin-offs, consulting firms, and education technology companies that often qualify for R&D tax credits through university partnerships and applied research projects. Tempe’s thriving startup scene — centered in Downtown Tempe and the Mill Avenue District — requires specialized CPA expertise in founder equity compensation, qualified small business stock (QSBS) planning, and early-stage cash flow management. Technology service firms and consultancies must navigate Arizona’s Transaction Privilege Tax on professional services while optimizing entity structures to leverage the state’s favorable 2.5% flat income tax rate. Commercial real estate investment in areas like Tempe Marketplace and the Rio Salado corridor benefits from cost segregation studies and 1031 exchange planning. SDO CPA serves Tempe business owners with expertise in startup and early-stage accounting, R&D tax credit documentation, technology sector TPT compliance, and multi-state tax planning for companies scaling beyond Arizona. From ASU research labs to Mill Avenue startups, we provide growth-focused tax strategies.

Arizona Tax Planning Tip

Arizona’s flat 2.5% individual income tax rate (effective 2023) is one of the lowest in the nation. For S-Corp and partnership owners, this means pass-through income faces minimal state tax. However, Arizona’s Transaction Privilege Tax (TPT) — the state’s version of sales tax — applies to many services that other states exempt, so verify your business activities aren’t triggering unexpected TPT obligations.

Tempe is home to 15,600+ small businesses and a population of 189,174. From Technology, Higher Education, Professional Services to professional services, Tempe business owners need CPAs who understand High concentration of startups and early-stage companies requiring equity compensation planning and founder tax strategies and can provide year-round tax planning — not just compliance.
