Donald Bast

Managing Director

For more than 35 years, Donald (Don) Bast has helped businesses surmount state and local tax challenges. With significant years of experience in the areas of state income and sales tax, Don assists companies as states aggressively seek new sources of revenue and to expand the tax base.  He helps clients interpret nexus standards, become compliant and develop strategies to combat the states’ efforts to shrink exemptions and expand taxation.  Don also works with clients to outsource compliance allowing internal resources to devote their time to planning and tax and business functions considered more critical.

Over the years Don has assisted many clients with nexus studies, transactional analysis, voluntary disclosure, audit defense and appeals, sales and use tax process improvement and automation, refund reviews as well as both sales and use tax planning, and compliance outsourcing.

He is adept at understanding compliance requirements, tax laws, and client systems and needs, so that returns are filed and payments are made in a timely manner. His client base includes utilities, technology, manufacturing, health care, retail, distribution, and wholesale.

  • For a health-care corporation, saving  more than $750,000 in potential back-due liabilities, penalties and interest;
  • For a manufacturing concern, reducing audit liability by $300,000;
  • For numerous other clients, conducting successful reverse audits and reverse refund reviews;
  • Taking over a client’s compliance and significantly streamlining the process to reduce the cost to the client.
