Welcome to Sales Tax Defense

Sales and use tax laws are often confusing, and at times cryptic. Failure to comply with the sales and use tax rules can lead to tax assessments, interest and penalties. The corporate officers and owners can even be held personally liable for these amounts due.

Substantial under-reporting, whether intentional or by accident, almost always results in penalties and can lead to a referral for a criminal investigation. Remember when you are under audit, the sales tax auditor is looking to issue your business the largest assessment legally sustainable.

Our sole mission is to help businesses, fellow professionals, accountants, attorneys, and their clients understand and comply with the sales and use tax laws. When there is a problem, we work for you to quickly and cost-effectively resolve the sales and use tax issue. Our focus is to minimize the amount you may owe and to defend your tax position.
