Deziel's Tax Service has been serving taxpayers in the Minneapolis–St. Paul Twin Cities area since 1991. We specialize in self-employed and small-business tax returns for artists, writers, musicians, performers, and related production workers. We also prepare returns for taxi and rideshare drivers, delivery drivers, salespeople, and many other independent workers.

We are familiar with the proper reporting of investment income and income or loss from rental properties. We are also experienced with the full range of credits: Earned Income Credit, Child Tax Credit, Childcare Credit, Education Credits, Adoption Credit, Residential Energy Credit, and Retirement Savings Credit.

We prepare state returns for Minnesota, Wisconsin, Illinois, Iowa, and North Dakota. Other states take us a bit longer. State returns are prepared alongside your federal return — we do not file state returns separately, unless a client is applying only for a Minnesota Property Tax or Rent Refund.

At Deziel's we stand behind our work and are available throughout the year to answer questions or help resolve issues with the IRS or state revenue departments. If you receive a correction notice or an audit notice, contact us right away. Most issues are resolved rather easily. If you are audited, call for Mark Deziel as soon as possible — he will go with you, and he has never charged an additional fee for attending an audit.

We assume you want to claim all of your legitimate deductions to get the biggest refund from an experienced and reliable preparer. When you come to Deziel's Tax Service, you can be confident your return is accurate and done correctly.

Staff Training

Employees of Deziel's Tax Service take part in intensive annual tax preparation training courses. All employees are registered with the IRS and hold PTINs (Preparer Tax Identification Numbers).

Our History

Nearly seventy years ago, John Weinard started doing income tax returns for clients in the back of a drug store in South Minneapolis. After acquiring experience and a loyal clientele, Mr. Weinard established an office on 4th Street. After the construction of I-35W took out his 4th Street office, he relocated to 1922 Clinton Avenue South.

In his first year out of college, Mark Deziel trained as a preparer at a firm called Mr. Tax. While doing a co-worker's return at the laundromat next door, he learned that John Weinard was looking for help. Mark worked for John for the next 13 years.

In 1991 Mark opened Deziel's Tax Service, renting space in a law office at 2620 Nicollet Avenue South. In 1998 John Weinard joined Mark at the Nicollet office. After the Nicollet building was sold, the practice operated from Calhoun Square, then for many years at Rosedale Center. In 2024 we moved to our current permanent home: 70 County Rd C West, Suite 702, Little Canada, MN 55117.

John Weinard was born in August of 1916 and grew up with his family on Nicollet Island. He served in the Civilian Conservation Corps, worked as a civilian at a U.S. airfield in Greenland during WWII, and built a successful career in bookkeeping and financial matters before beginning his tax practice. By taking a deep and genuine concern for each client, John built a solidly loyal following of people from all walks of life — factory workers, teachers, nurses, stock brokers, construction workers, and yes, even a lion trainer.

As the south Minneapolis neighborhood diversified and the practice moved to Calhoun Square and then Rosedale, John prepared returns for people from all over the globe. On December 19, 2010, John Weinard passed away at 94. We miss him, and we continue the practice he built.
