Dayton, OH Business Tax Preparation Services

Conveniently located at 8157 North Main Street in Dayton, Gudorf Tax Group is an Ohio tax preparation company with over thirty years of experience in bookkeeping, payroll services, tax preparation services, and accounting services.

Originally established in 1981 by Shelley L. Denney, the firm has served hundreds of clients seeking meticulous, experienced work along with personalized attention and service. We are proud to have developed relationships of long-standing with many of our clients, who have come to rely on us year after year for tax work as well as the payroll, accounting, and bookkeeping that keeps their businesses running smoothly and efficiently.

We serve individuals and businesses, with a particular concentration on small business accounting and payroll services. Many of our clients have businesses that are large enough to have complex bookkeeping and accounting needs, but small enough that it is not practical for them to have an in-house accountant. We take pride in partnering with our business clients to manage these important functions so that they can devote their attention to promoting the growth and success of their businesses.

What Sets Us Apart

What keeps clients returning to us for their tax, accounting, and payroll needs, and draws new clients to us?


We’ve served the Dayton business community for more than three decades. Unlike newly-established or seasonal tax service providers, this is our lifelong profession and vocation. We routinely handle extensive and complex tax filings. Our clients can be confident that their work will be handled by someone with years—not weeks—of experience.


As tax, bookkeeping, accounting, and payroll technology evolves, we keep pace. We use the latest software, including Client Write Up, and we can help clients set up and manage their own bookkeeping software to streamline their processes.


Our clients are more than a file number to us. We know them, know their businesses, and respond to their needs. We consider ourselves partners in their success.

We invite you to explore our website and to learn more about the services we offer and the free tax planning and financial tools we make available.
