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.

Fast service!

My wife and I were in search of a new accountant and decided on MZ Accouting. We met Mo and his wife on a Tuesday, dropped off our forms, and was told it would be done in a few days. A couple of days later, we got a call that our returns were ready. We were satisfied with the work and look forward to getting our taxes done by MZ Accounting.

knowledgeable, and reasonable fee!

I have had my personal taxes done with MZ Accounting for the past 3 years and I have found Mr. Mo to be knowledgeable, educates me about the updated tax laws, pros & cons, is timely, easy to reach, answers emails and questions same day or next, charges a very reasonable fee and is a nice person to top it off. I feel like I’m in good, solid hands.

Extremely helpful in some difficult times

Mo and MZ Accounting & Tax have been extremely helpful especially in some difficult times. After my father passed away a few years ago , my mother needed help with tax related issues, and Mo, without hesitation (and without my parents being  his client) was quick to offer advice and provide support. MZ accounting has been doing my taxes for the past 4 years and they are now handling my mother’s taxes as well. I wholeheartedly trust MZ Accounting and Tax. Great people!

Mo has been doing our income tax return for the past few years and we couldn’t be more pleased!  We are very appreciative of Mo’s knowledge, dependability and attention to detail. He is quick to answer any questions and emails and has made great suggestions that have improved our tax preparations.  Mo has been very professional and friendly and he makes dealing with their business a true pleasure.

As a professional I have specific needs and expectations that can not be met by most accounting firms. MZ accounting and Mo specifically were so helpful throughout my whole experience. From on call advise, thoroughly explaining all my options to me, and pros and cons of all options. As a small business owner myself I really am happy to find a firm that can meet all my needs and demands. IF I COULD GIVE 10 STARS I would they were so phenomenal and amazing. Did I just say that about an accountant,LOL. Thanks again Mo!

MZ Accounting is one of the finest business establishments I have had the pleasure of utilizing and Mo and Azinne are the two most pleasant and knowledgeable accounting experts responsible for this establishment. 

Mo and Azinne have been helping us with our personal tax returns for the past few years. Their accounting service has been flawless and has helped us obtain our proper returns year after year.  

We were unexpectedly audited last year by the IRS and Mo quickly jumped to action after we reached out to him for assistance. He personally contacted the auditing offices and advised us in detail of what to provide and steps to take to resolve our audit issue.  We were confident that Mo’s tax returns were correct so we did as told, and satisfied all the auditing requirements with no complications and no further inquiries from the IRS. 

We fully trust and endorse MZ Accounting’s friendly, accurate and timely services.
