I highly recommend Jim Grennan! I highly recommend Jim Grennan as an accountant and for his tax resolution services. He’s extremely knowledgeable, patient and helpful. His direction and guidance is top notch. I’ve worked with Jim for years and he has always gone above and beyond. He truly cares.

Trust Jim To Get The Job Done ! In 2016 I found myself in need of filing for Bankruptcy. As part of the process I had to bring all my Federal & NYS Tax Filings up to date. Believe me it was no easy process . I needed to go back years to get the job done. My Bankruptcy attorney recommended Jim Grennen. Without Jim's extensive knowledge and his uncanny ability to navigate the various Federal & State tax codes I would have been lost. Not only did Jim help me with my taxes but I made a friend.

thank you!!!! I called Jim Greenen to get help with my tax situation that was very complicated and he was very friendly and helpful. He took the time to explain what to do and I felt very relieved. I was given great guidance and direction. The support he provided me was greatly appreciated. Highly recomended!!!!

You Won’t Find Anyone Better, anywhere else! A while ago we were in a jam. ( Wife & I) Garnishments, liens, even bankruptcy. We heard horror stories about those TV and bigger so called Tax Resolution companies. But we were desperate. I don’t remember what brought me to James Grennen of LI Tax Resolutions but we have absolutely no regrets. He has over exceeded our expectations. Over the years Jim has guided us and helped stay out of trouble. At this point we do call him a friend and look forward to his continuing services now and in the future. The IRS is ruthless and will stop at nothing to get what they want. So if you are on the IRS’s Radar. LI Tax Resolutions and James Grennen is the Radar jammer that you need. Just like myself. You won’t have any regrets.

Extremely professional, highly knowledgeable and focused on your individual and unique concerns. I was recently widowed and unbeknownst to me, I inherited a voluminous collection of "Unpaid, Intent to Levy" notices from both the IRS and NYS. Upon receiving a recommendation from our long term and trusted accountant, I hesitantly contacted Mr. James Grennen and informed him of my plight. In a very professional manner, he quickly understood my unique needs and concerns and with a great deal of compassion, he formalized an individualized plan required to ease my fears and apprehension. His extensive experience in dealing with the governmental agencies involved was priceless and highly effective. I will be eternally grateful for his assistance and his concern and diligence regarding any obstacle encountered while resolving my "Tax Situation". Without any hesitation, I highly recommend this gentleman for any taxation issues or concerns that you may encounter in your life. Thank you again, Mr. Grennen.
