Tax and property sale
The world of tax liens is complicated and financially dangerous. Tom made the problems clear and simple, for everyone involved. His ability to clear road blocks and minimize expense was a god send. He work diligently to make pending dead lines, and was always available for consultation. Thank you, Tom.

Honest and Upfront
Tom Morrison worked hard for me in abating some tax penalties. He worked within what the tax code would allow. He was honest with me letting me know that we were not guaranteed to receive any monies through our efforts. He mentioned I had a good chance but helped me to keep my expectations at bay. Tom created a case for me and after patiently waiting we heard back from the IRS. We won, my tax penalty was abated. I was very surprised to hear the news. I was grateful for Tom, his diligence and hard work, and most of all his honest and upfront approach to handling my tax situation.

Tax Law Defense
I hired him to help defend me when the State of Montana department of revenue did an audit and claimed that I could not claim educational expenses related to improvement of my skills as a physician. This was an extremely stressful, nearly two year ordeal, during which I became discouraged and distrustful. Many times and wanted to just give in, even though I felt that I had the right to claim these expenses. During this process, at multiple times, Tom Morrison would take time to explain his mindset and encourage me to continue, each time giving me the option of stopping the process. He continued to interact in a friendly and cordial manner with all parties involved, even in the final trial. He helped me understand the legal process through a far more objective lens. Tom Morrison is extremely professional and a man of very high integrity. I would trust him with any future legal questions.

Probate and Taxes
Tom, Heather, and Sarah are amazing to work with! I found Tom when I was looking for someone to help with probate, I was out of state, and it was an unusual situation. He made things so easy! Tom is highly knowable, and the whole team is very responsive, friendly, and always able to answer questions. They made a difficult process so much easier, I’m not sure how I would have navigated it without them. Tom went above and beyond by helping my amend my returns after the estate closed, saving me a significant amount of money. I would have had no idea to even look at this without his expert guidance. I highly recommend Morrison Law Firm; great people who really know their stuff!

Business and Family
Tom Morrison has done our legal work for eighteen years, both commercial and private. He helped us restructure our C Corporation, drafted leases for commercial property, our personal wills and Power of Attorney’s. He is an excellent tax strategist which is essential for long term decision making. Tom has always worked with obvious wisdom and clarity regarding the legal and tax matters that we brought before him. He is personable and devoted to his family, which in turn makes him caring when it comes to taking care of our own family. Recently I faced a medical issue that required that my estate planning be reviewed and updated quickly. Tom and his staff worked diligently to have the essentials covered and ready for me to sign before I needed to leave for medical consultation. My wife and I highly recommend Tom as a lawyer because he has done such a professional job for us.
