Accounting & Tax Services in Tucson, AZ
Tucson serves as Southern Arizona’s economic center and a global leader in aerospace, defense, and optics innovation, with over 18,500 businesses anchored by Raytheon Missiles & Defense, Davis-Monthan Air Force Base, and the University of Arizona. The city’s optics cluster — concentrated in the Tucson Tech Corridor and Rita Ranch — produces more optics and imaging systems than anywhere else in North America, creating substantial R&D tax credit opportunities for manufacturers and research firms. Defense contractors working with Davis-Monthan face complex federal cost accounting standards (CAS) and indirect cost allocation requirements that demand specialized CPA expertise. Tucson’s tourism and hospitality sector in areas like Downtown Tucson and the Catalina Foothills generates significant revenue but requires careful TPT compliance as Arizona taxes many services. SDO CPA helps Tucson business owners navigate federal contract accounting, maximize R&D credits for aerospace and optics innovation, structure cost segregation studies for commercial properties in emerging districts like the Mercado District, and optimize S-Corp distributions to leverage Arizona’s favorable 2.5% flat tax rate. From government contractors to research spin-offs, we provide specialized accounting for Tucson’s unique economy.
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.
