Working With Us

Welcome to The Tax & Business Consulting Group Inc

At The Tax & Business Consulting Group Inc, we believe that no business should go it alone, especially in the early years. That’s why our founder, Jim Upshaw, has built a practice specifically designed to support startups and entrepreneurs across Illinois and beyond. With over 42 years of tax and auditing experience and more than 25 years running his own firm, Jim offers seasoned, practical guidance rooted in real-world success and experience. Whether you're seeking tax preparation, strategic tax planning, or full business consulting services in any state, we're here to help you take control of your finances and build something that lasts.

The Tax & Business Consulting Group Inc serves a wide range of clients, from individual entrepreneurs launching their first LLC to seasoned business owners navigating complex tax problems. Many begin with business entity formation and continue with us through succession planning, nonprofit tax filings, and even IRS tax resolution.

But our real strength lies in our “one-stop” model. Our team partners with trusted attorneys across key specialties—trusts, trademarks, civil litigation, and bankruptcy—so we can offer truly holistic solutions. Whether you're seeking accounting for startups, nonprofit tax services in the greater Chicago Area, or business valuation consulting, we’ve got you covered.

Clients choose us because we take their vision seriously, and we deliver. You’ll work directly with Jim, a martial arts, sports, and chess enthusiast, and yes, a man who once trained with Bruce Lee for several sessions. 

His concierge service approach allows Jim to give every client focused, personalized attention, and brings the same energy to your business as he brings to his morning mile runs.

If you’re a new or growing business in need of local or nationwide small business tax services, entity selection guidance, or just a seasoned expert who’s seen it all, we’d love to connect. We live by the philosophy that “we’re greater together than we are separately”—and we’re ready to prove it.
