What People Are Saying

“I operate an IT consulting business and have a rather complicated tax situation, due to being a dual citizen of the United States and Canada. Michael not only files my personal taxes for the U.S. and Canada, he handles all of my Canadian income and GST tax filing, as well as provides ongoing planning and advice. I have worked with several accounting firms over the years and Michael is by far the best I’ve worked with. I can’t recommend him enough.”

— Josh K.

“MJS is the best! For the last 8 years, Michael has been managing my taxes in both Canada and the U.S. He is professional and extremely knowledgeable. He has provided me with excellent service and has always given me solid advice. I feel very fortunate to have found Michael and look forward to working with MJS for many years to come.” 

— Marita N.

“Becoming the owner of a business with ties to both Canada and the U.S., while having personal tax obligations to both countries, was not seamless or simple. I thankfully found Michael Shomali, and I can't imagine doing business without him. Since I became an MJS client in 2013, I've come to trust the excellent service I have received from our first contact. Their integrity, competence, and professionalism are unparalleled in my experience and I am confident in recommending them for tax services of any kind.”
