Sales & Use Tax

Lower your tax burden. Reduce your tax risk.

Understand your tax exposure and limit your liability.

Thousands of state and local jurisdictions impose sales and use taxes, many with conflicting positions about which has regulatory authority and how much is owed. 

Factor in economic nexus standards for remote sellers and marketplace facilitators and it’s easy to see why companies struggle to maintain compliance with sales and use tax regulations. 

BDO helps companies understand their sales tax exposure, mitigate risk and establish processes and systems to effectively manage ongoing compliance. Our nationwide network of sales and use tax professionals draw on a range of backgrounds and work experience beyond public accounting. Many are former sales and use tax auditors from state tax departments or have worked in some of the largest multistate tax departments in the country.  

We serve as trusted advisors, offering tailored services and technical support—all backed by extensive government and industry experience.
