White Collar Criminal & Federal Defense Attorneys Trusted Nationwide
Allegations of sales or excise tax fraud place everything you’ve built at risk—your business, your professional standing, and your personal freedom. These cases are rarely simple accounting disputes. They are aggressively investigated, often prosecuted as criminal matters, and carry the potential for devastating financial penalties, public exposure, and incarceration.
At Chapman, Dowling & Mallek, we understand that sales and excise tax cases demand more than technical tax knowledge. They require strategic defense, discretion, and a deep understanding of how tax authorities and federal prosecutors build fraud cases. This overview explains what sales and excise tax fraud defense truly involves, what is at stake, and why early, experienced representation is critical.
From a legal standpoint, sales and excise tax fraud defense centers on protecting individuals and businesses accused of intentionally underreporting, misrepresenting, or failing to collect and remit required taxes under federal, state, or local law.

Sales and excise tax cases are pursued by multiple agencies, often working together. Investigators may include:

The consequences of sales and excise tax fraud allegations can be severe and long-lasting.
The financial impact is often compounded by public scrutiny and loss of trust.

These laws are highly technical and constantly evolving—making experienced legal interpretation essential.
