ABC Tax Service, The Business

As far as I know this is how the business was originally started:  Barbara Cooper started Cooper Tax Service many years ago.  I have been told she prepared tax returns out of her home.

Bill Christianson bought Cooper Tax Service in 1986 and changed the name to ABC Tax Service.  Bill grew ABC Tax Service and started a side business of helping people with tax problems and filing old tax returns.

I, Sherry Daugherty, started working for Bill in the summer of 1992 as a receptionist.  I very quickly went from being a receptionist to assisting Bill with everything he needed done.  This included tax returns, filling out IRS and Minnesota forms for our clients who needed payment agreements, offer in compromises, etc., to doing payroll for the office, payroll forms for customers, accounts receivable, accounts payable, etc.,.  I eventually took over running the tax preparation portion of the business during the tax season. In 1998 Bill decided to retire and sold the ABC Tax Service portion of his business to me.

I have learned quite a lot about running a business, having employees and especially making customers happy.  I think the most challenging part of this business is having the office run smoothly.  The smoother the office runs the happier the customers are with our service.

Thank you for stopping by.

I have been with ABC Tax Service since 1992, I started out as an employee and in 1998 I bought the office from my boss when he retired.  I have been running the business with my husband since. .

I have a Bachelor’s degree in accounting from Kaplan University.  While attending school for my degree my husband and I decided to focus on tax preparation and helping people with their tax needs. While there is no degree required for tax preparation in the state of Minnesota I am always taking classes offered to keep up on my knowledge for tax return preparation.

My husband and I are both from the East Side of St. Paul, we both attended Johnson, although we both ended up at other schools for a period of time.  We married in March 1996, we have five children, Bradley is the oldest, he died in 2010, then we have Julie, Rebekah, Andrew and Nicholas.
