What's different about running a business in Round Rock?
Round Rock grew up around a major tech employer, and its small businesses still reflect it: IT contractors and consultants, hardware and logistics suppliers, healthcare practices serving a fast-growing population, and retailers along the I-35 corridor and the outlet district.
Tech contractors often bill through their own LLC and need quarterly estimates, a solo 401(k) and an S-Corp check. Suppliers and retailers need inventory, sales tax on every Texas sale and, for online sellers, nexus checks in other states. Healthcare practices need payroll for clinical and front-desk staff.
Most of Round Rock is in Williamson County and renders business personal property to the Williamson Central Appraisal District, with a small part of the city in Travis County. Renditions are due April 15.
What does a typical Round Rock client need from us?
Quarterly planning for contractors, inventory and sales tax for retailers, and payroll for practices, all handled by one accountant who also files the federal and Texas returns.
