I typically do my own taxes, but go to MJM for the tough returns. Mark and the rest of the staff are great, friendly, and always helpful. Mark was able to give me some valuable tax advice as well.

Mark has been doing my taxes for about 4 or 5 years now and I am beyond satisfied! My taxes always seem so complicated to me since I own a business and also have to do personal taxes, Mark always makes sure I get taken cared of and makes sure it all goes very smoothly. The staff is always so friendly and welcoming too!. I highly recommend MJM Income Tax!

Maria L Menconi

Mark Miller has assisted is with our taxes for the past 3 years. We were long time clients of another Tucson accountant who retired when we decided to try Mark. We were skeptical, having been very well taken care of for many years. MARK HAS DONE AN OUTDTANDING JOB. Always thorough, always looking to help us find the routes that might assist us. This year, we received a substantial refund due to his work and we were stunned. We don't ever expect that and what matters to us is that Mark is honest, forthright and helpful. Thank you MJM Taxes.

Stephen Keyes

MJM is AMAZING & ACCURATE! I’ve always used EA’s (IRS ENROLLED AGENTS) to do my taxes but MJM has been the best I’ve ever used. They’re honest, fair and ask all the right questions. I feel blessed to have used them. Just today they emailed me an update that may increase my return - yippee!

Judy Fisher

We moved to Arizona January 2019. We have always done our taxes on Turbo Tax, but since our returns were going to be a little more complicated this time, we contacted Mark. First, we had a no charge appointment with him to review our 2018 return and to get some advice about 2019. When it became time to do the 2019 taxes, we returned to Mark. He was fast and efficient with doing all of our returns and saved us more money than we would have saved had we done our own returns.

Don Hue

I am a first time customer. I was referred to MJM by a friend as my tax preparer retired. This group is professional, appears to ask the right questions and my return were prepared and delivered in a timely manner. I hope this relationship is long lasting.

Elizabeth Catroppa

Love MJM! Mark is very knowledgeable and straightforward with his answers to my questions. I appreciate his honesty. His staff is helpful and respectful. I only wish I had gone to him sooner!
