John is by far the top tax lawyer in Colorado. I called around and many of his competitors will scare you into much higher rates, at a time your most vulnerable.

John was different. He is like having both a friend and a professional represent you. He follows up with you and the IRS promptly, and let you know all of your options at an affordable man rate. Truely a godsend. Thank you John

John McGuire has been an excellent attorney for us, but he has also been a tremendous wealth of information on a variety of business issues. He is learned, thoughtful and insightful. He is committed to getting you to the finish line and meeting your needs on any project, acquisition, legal matter or tax question you may want action or an opinion on. I recommend John if you want a great attorney with a breadth of knowledge.

John and the team at McGuire are unbelievably good. The IRS and the State of Louisiana were after me for a total of $325,000 in unpaid payroll taxes for the family business that I was affiliated with years ago. This situation was threatening to tear my marriage and my entire life apart.
When the situation hit me, I contacted a dozen law firms and received a lot of "gloom and doom" talk along with requests for me to visit them and pay for a consultation. John was different - he was on it from the start and had a positive outlook. He was very easy and pleasant to work with always worked around my schedule. He and his team were so good throughout the entire process in managing both my case and my anxieties. John is extremely knowledgeable and was always genuinely optimistic about my case (much more optimistic than I was). The hard, smart, optimistic and aggressive work of the people at McGuire paid of as they got my personal liability reduced from $325,000 to $0! John and the the team got goth the IRS and the State of Louisiana to clear my record and drop all collection activity against me. The most incredible part is that McGuire got this done within 5 months after I engaged them! There is no doubt in my mind that John and the team at McGuire are the best out there.

John has been a resource to several clients who have need bookkeepers, taxes filed, and/or an estate plan completed. He has offered me many consultations to discuss these same items with him during the pendancy of my clients' divorce cases. I appreciate all that John has done for these families.

John assisted us with our case for quite a while and we are very happy with the results. He became a friend through the process and is easy to talk with, is very open and honest with us and he is trustworthy and competent.

Retaining the services of John McGuire as my tax attorney has proven to be one wisest decisions I have ever made. Dealing with the IRS in resolving tax issues can be a most intimidating and frustrating experience. John has taken that burden off of my shoulder by taking point in the efforts to reach an effective resolution to my tax problems. I highly recommend John to anyone needing expert assistance with tax issues. His compassion, patience, and experience have been invaluable.

I have worked with John for over 10 years on various issues and he has always provided me with great solutions. His knowledge of the tax code and his ability to negotiate have resulted in great outcomes. I would recommend his services to one and all

John McGuire is an excellent tax attorney. My experience with him has been fantastic. His advice is tempered with expert knowledge of tax law and how the IRS operates along with true concern and effective advocacy for his client's position. He has proactively followed up on matters and consistently kept me informed of the status of pending issues. I am happy and relieved to have John McGuire as my counsel and recommend him to anyone who wants or needs tax help for their business or personal matters.

John McGuire helped us with our major IRS matter, where no one else could within 6 months from beginning. Our other contacts took over 4 years with no progress in settling our issues. Were told by others to "File Chapter 7" , then go to Federal Court and ask the judge to forgive the debt! Our comment to them was "Do not need you anymore" that was our last conversation with these advisors! They were only interested in taking our money.
John accomplished our matter with the IRS within 6 months. From the beginning, John set a plan in motion protecting our family and business. His expertise, education/knowledge helped us through our situation.
A family friend recommended John, he spoke very highly of him and also helped him in a similar situation with the IRS.
We are so very grateful to John. He helped us out of this scary situation, and accomplished what others could not in 4 years, he was able to fix in months for us.

Thank You John! We have our life back, and are so very thankful for all you have done, being honest and truthful, we cannot express enough thanks.
Jay and Irene.

I am located in New Mexico and John McGuire has restored my faith in attorneys. From the very first contact he appeared to care about my situation. Unlike others that the only thing they seemed to be concerned with was their financial gain. He has always been prompt at responding to my emails and calls. He has achieved a settlement with the IRS and was able to stop all the harassment. I would highly recommend John McGuire to anyone that needs assistance with the IRS!

John McGuire is an outstanding business attorney. He provided very thorough information to allow me to choose the best business entity and continues to provide me with the necessary guidance to help me make sound decisions for my business.

Without question, John & his team saved me $$$$$ on my case against the IRS. Always Very professional & Cost Efficient.

Thanks again The McGuire Law Firm !!.

Amazing experience with John McGuire. I had quite a bit of anxiety about finding a tax attorney that I could trust, but now I know that was a silly thing to worry about with John. He not only helped me sort out my current tasks with the IRS, but is helping me plan for a more organized tax future. John is very responsive to both calls and emails, and setting up meetings is a breeze. I have no intention of using any other business tax attorney as long as John is in Denver. His website is also very informative with a full archive of easy to find articles written by John himself.

John McGuire has been my solid tax and business attorney for over 5 years and has handled everything from navigation of IRS matters to straight forward business transactions. John's consult is exceptional and he genuinely cares about me, my family and my business.

John McGuire changed my life!! I hired John to be my tax attorney for a tax matter whereby I was held responsible for 941 employment taxes. I spent thousands of dollars with another firm attempting to resolve this matter with no results. For a very reasonable fee, John was able to completely resolve my case in a very reasonable time period. John’s knowledge of IRS issues and procedures was second to none and definitely what I needed. The penalty assessed against me was completely waived. John truly cares about his clients and goes the extra mile to help.

John McGuire is an excellent Tax Attorney. He is very knowledgeable in tax and business matters, and always responds quickly to my questions and needs in a thorough and thoughtful approach. I will continue to use him for any and all my tax matters and I highly recommend him!
