Meet Our Founder
Gerald J. Donnini II, Esq., founded Sales Tax Helper LLC to address a pressing need in the business community: simplifying the confusing and often overwhelming world of sales tax compliance. With over a decade of experience as a sales tax attorney, Jerry witnessed firsthand the frustrations businesses faced when relying on cookie-cutter software solutions that lacked human interaction and meaningful expertise.
Many of his clients came to him after struggling with software companies offering generic approaches, outsourced support teams with little to no U.S. sales tax experience and limited personalized guidance. He recognized that what businesses truly needed was a balance—leveraging the efficiency of software while providing access to knowledgeable U.S. lawyers, CPAs, and sales tax professionals who could create customized solutions for their unique challenges.
Jerry’s vision for Sales Tax Helper was to empower businesses of all sizes, from small startups to large enterprises, with a platform that combines simplicity, efficiency, and expertise. Whether it is expert-designed tools for managing compliance independently or full-service representation for audits, appeals, or litigation, Sales Tax Helper is built to deliver solutions tailored to each company’s specific needs.
Today, Sales Tax Helper embodies Jerry’s commitment to helping businesses navigate the complexities of sales tax with confidence and ease. Backed by a dedicated team of sales tax professionals, including former auditors, CPAs, and experienced tax attorneys, Sales Tax Helper combines innovative technology with human expertise. This powerful blend ensures businesses can tackle their sales tax challenges efficiently while staying focused on what truly matters: their growth and success.
