Mr. Callahan returned my call same day. He was extremely helpful with information.

Great Company. I called and Spoke to Mr. Callahan. I was looking for some advice for myself and husband. Mr. Callahan was wonderful. He didn't rush me off the phone, he explained everything in a way that made sense and was very friendly. He was really knowledge and he cared more about giving me good information than tying the phone call up. You won't be disappointed working with them

Mark Callahan was very knowledgeable and willing to assist any way he could. If you're going to trust any lawyer with your tax problems, this would be the one.

Very helpful. Gave us some quick insight to our problem. Would recommend.

Great council. Very informative, wasn’t eager to take my money. But eager to help. #1 for taxes

Joe is a great Attorney. I was a little nervous at first with my tax situation
with IRS. I got conflicting tax advice from my accountant. Mr Callahan got the IRS to waive over thousands of dollars of back taxes, interest and penalties. To any small business that endures a tax problem, I would highly recommend Mr Callahan.

In ALL of my personal experiences over the past years with any and ALL tax issues I've turned to Joseph Callahan, Esq. to resolve them in a very timely, intelligent, and informed manner. He has helped Myself, Family, Friends and is a very trusted ally. His services are greatly appreciated by us all!

I called to ask for advice and not knowing what to do. I never had problems with taxes until the last two years. I was given great advice on how to handle my situation. Thanks.

Mr. Callahan provided me with expert advice on all of my options regarding my tax debt situation. He was straight forward and honest about how the government would view my personal situation which has helped me determine my best course of action moving forward.
Thank you so much!

Gave me great advice on how to fix my taxes and get my money back.

In December I received notice of over $130,000 in sales taxes due for 2014 and 2015. I found Joe Callahan on the web and three months later the case was completely resolved. No taxes due. No penalties.
