Welcome to Un-Tax-Able!

I got started in the tax preparation business out of frustration. After I graduated from Baruch College I became an entrepreneur. I started several businesses with friends and relatives, but I was at the mercy of the tax system. I did not understand the whole system and felt that I was paying more than I had to. My tax preparer would not explain anything to me, he would just tell me where to sign and how much I needed to pay.

I needed to understand the whole process and not spend days waiting for my tax preparer to finish my taxes. So, In 1999 I took the H&R Block tax course. It was very intense and I learned a lot from the course. By the way, if you want to learn about taxes, the H&R tax course is a great course to get started.
After completing the H&R tax course, I was offered a position as a tax preparer in one of their Bronx locations. I gained a lot of valuable experience preparing a large number of tax returns for H&R Block. The following year I was promoted to manage one their bigger Bronx offices. There I learned the ins and outs of preparing taxes and managing a mjor tax firm. The office grew by about 20% per year the first two years I worked there. By the third year the district manager had changed so often, and I didn’t like the direction the new management was headed, so I did not return to H&R block for my fourth tax year.

Thanks to my experience working for H&R Block I learned to work with lower and middle income tax payers. At the Bronx location I managed, we work primarily with Latinos and other minorities; this provided me with the experience of preparing many different types of tax returns for a variety of tax payers.
In the following year, I worked with John Cisneros, an accountant based in Manhattan. John is very knowledgeable as far as working with higher income tax payers and preparing tax returns. By working with John I learned how to prepare for audits and how to organize a client’s records so they have a good chance of winning a tax audit. After a year with John I was ready to begin my tax firm, and in November of 2003, Cristian Martinez and myself co-founded and started Un-Tax-Able

I was born in the Dominican Republic and raised in New York City, and because of this I feel that I have a unique understanding when it comes to the Latino community. I feel I can offer an understanding that not many tax preparers can. I’m able to understand the point of view of a variety of Latinos, from the recently migrated immigrants to the US born individuals who have been in the US all their lives. I studied many subjects in school and gained many learning experiences in my careers so I know how to relate to the issues related to those of taxes. I have also been a part of the financial market for some time which allows me to understand how stocks, commodities, insurances, and other financial products affect your tax situation. I understand small businesses from the ground up, having owned and worked for many small businesses in my life.


I graduated from Baruch College in 1989 with a BBA in Industrial Organizational Psychology. I took the H&R Block Tax Course in 1999. I Became an Enrolled Agent with the IRS in 2003. I’m a member of the National Society of Tax Preparer, National Association of Enrolled Agents, American Institute of professional Bookkeepers, Professional Bookkeeper with Universal Accounting, former member of the National Association of Tax Preparer, and member of the American Association of Notaries.


Married with three children and live in Bronx, New York.

Dear Friend,

I hope you’ll forgive me for being blunt.

I am Mario Abreu, I’m an Enrolled Agent (EA) and realize that you may not be used to seeing a tax professional talk like this. It’s not my intention to offend (I’m actually being very careful with my words–I am a tax professional, after all).

But I think you’ll agree that the times we’re currently facing require a little straight talk.

Here’s a certain truth: the State and Federal Government would love to have more of your hard-earned money in their accounts. Sure, even though it’s painful, none of us begrudge paying our legal and fair share of taxes. But the problem is that regular taxpayers, like you, are missing out on legal and safe deductions, to the tune of hundreds of millions of dollars in unclaimed refunds every year!

As a tax professional, it truly breaks my heart, knowing that just a few thousand, or even a few hundred bucks for us “regular guys” out of that vast pool of overcharging could make a world of difference–and they are just sitting there, unclaimed! And with the economy we’re facing now…it’s essential that the “right” professional handles your taxes and other financial matters.

You see, all tax professionals are not the same. From the “discount” chains (notice the quotes) to classic accounting firms, most fly through tax season in a disorganized mess–bleary-eyed and hopped-up on caffeine. It’s no wonder that they treat you like a number and lapse into excuses and tax-talk. (I told you that I would be blunt.)

Feel free to poke around our site and discover why I’ve been called “The Most Trusted Tax Professional in the Bronx, NY Area.”

Talk again soon,

Mario Abreu, EA
