About Us

Our Firm

IN MY HOME TAX SERVICE was founded in January 1975 by John Valko. For 47 years we have been providing quality, personalized financial services to local individuals and small businesses in Southeastern, WI. out of my home office. Thus the name, “IN MY HOME TAX SERVICE“. During the last 47 years we have primarily served the SE Wisconsin areas of Racine, Kenosha and Milwaukee. Due to a recent move, our office has relocated to Jackson, WI and we have added the communities of Germantown, Jackson and West Bend to the areas we offer our services. Our expertise is in small business and personal tax preparation, bookkeeping and payroll services. Further, we understand that the tax season doesn’t end on April 15th and we pride ourselves on being available to our clients year-round. Unlike the other big box stores that disappear after April 15th, we are here for you and available to you year-round.

In 1975, I started IN MY HOME TAX SERVICE working out of a very small office in my basement preparing taxes for a few friends and family. Over the last 47 years that all changed. IN MY HOME TAX SERVICE has seen significant growth and has grown into being a full-time year-round tax, bookkeeping and payroll service. Over the years I have prepared thousands of tax returns and have many hundreds of clients in the SE Wisconsin area, clients in 14 other states between the east and west coast and 1 client in Japan. Through the combination of expertise and experience we can assure you that every client receives the close attention they deserve. We know that our dedication to high standards and work ethics is the reason our clients return year after year.

Our Goal

At IN MY HOME TAX SERVICE, our goal is to help our clients lower their tax liabilities by optimizing deductions. Optimizing deductions involves working closely with our clients to fully understand their personal and financial situation and to recognize where there may be opportunities for tax savings. We strive to provide our clients with the information they need to achieve this goal.

Understanding that to do this, we must keep current on the everchanging tax laws, we attend many tax seminars and on-line study courses during the off season to obtain the required continuing education credits necessary to maintain our credentials as Registered Tax Return Preparers.

Our dedication to hard work has earned the respect of the business and financial community in and around the SE Wisconsin areas. We believe this to be a direct derivative of our solid reputation and responsiveness to our clients. Whether you are a current or a prospective client, you can be rest assured that individuals and businesses who choose to work with us will receive competent and timely advise. IN MY HOME TAX SERVICE is dedicated to meeting these goals with high standards of excellence and professionalism.


We work with you on a personal level to determine the best solutions for your unique needs, then leverage our seasoned expertise to achieve the best possible results.


We are your trusted partner in success. We offer a full range of professional services at a fair price while providing you with the individual attention that you deserve.


Rest assured that when a need arises, we are ready and capable to handle everything for you so you can focus on what matters most to you.
