What our clients are saying:

Tailored Service

MZ Tax has done my taxes for the last two years. They are always available to answer questions and plan for next year’s taxes. I have an LLC out of state and multiple investments but even if you have regular tax issues, you should give them a call.

Dustin B. review of MZ Accounting & Tax Service on Yelp


We switched both our business and personal tax services over to MZ Accounting and Tax Service after receiving a high recommendation for them from a well trusted business associate. They worked hard to clear up some issues that we were having with a past accounting service and we are truly happy with our experiences with this company…now we are now the ones to refer many of our family, friends, and business affiliates to them! You will be delighted with their high levels of customer service and professionalism along with their fair rates. Thank you MZ for taking the headache out of accounting for us!
