USiBTS is the best. Not only did they help me make sound decisions, but they also followed up with me to ensure I didn’t make any other mistakes! I highly recommend them for any tax needs and financial advice. They are too good!




We were experiencing problems with our overall tax system and was on a thin line, but fortunately, we found USiBTS, which not only swooped in to save the day but resolved it quite quickly.




USiBTS handle all my personal and firm issues. After delivering me from a nightmare of complicated tax problems, everything so far has been easy. They are fast, direct, customer-oriented, and the easiest-going company I’ve ever partnered with. Kudos!



I don’t know how to thank USiBTS enough. My business would have been history if they hadn’t shown up for me. In only 24 hours, they analyzed my past tax history and put together a detailed plan, even if it was short-noticed. It was unlike anything I’ve ever seen.
