Accounting & Tax Services in Addison, TX

Addison’s 4,800+ businesses operate in one of the Metroplex’s most concentrated commercial environments, with Class A office towers along the Dallas North Tollway, Addison Airport’s private aviation cluster, and over 200 restaurants creating a vibrant business ecosystem. The town’s unique structure—15,000+ daytime workers but only 16,000 residents—creates heavy reliance on property and sales tax revenue rather than residential property taxes. SDO CPA helps Addison hospitality businesses navigate the Texas Mixed Beverage Tax and hotel occupancy tax requirements, ensuring proper reporting across city, county, and state levies totaling 15% for hotels. For professional service firms in the Quorum Drive office corridor, we structure multi-partner LLCs to optimize income allocation while preserving qualified business income deduction benefits for high-earning professionals. Our team assists technology companies in the Addison office market—where Class A space commands $32-38 per square foot—in analyzing whether R&D tax credits from software development activities justify the documentation burden. With Addison Airport creating unique opportunities for aviation businesses, we help aircraft management companies, charter operators, and FBO service providers navigate the complex tax treatment of aircraft ownership, depreciation, and interstate commerce apportionment.

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.

Addison is home to 4,800+ small businesses and a population of 16,661. From Professional Services, Hospitality, Technology to professional services, Addison business owners need CPAs who understand High commercial property costs and intense competition from nearby Dallas and Richardson and can provide year-round tax planning — not just compliance.
