  • I really appreciated their professionalism and thoroughness. I can't recommend them highly enough! When I became overwhelmed with the thought of maneuvering through the U.S. Tax code to get my U.S. Tax filings up to date I was fortunate to have U.S. Tax IQ there to walk me through everything. They took care of all of the required paperwork and filings. And when it came time to consider rescinding my U.S. Citizenship, U.S. Tax IQ was able to present me with all my options so that I could make an informed decision. I really appreciated their professionalism and thoroughness. I can't recommend them highly enough! German N.

  • I wouldn’t hesitate to use this firm to help with this process and at least look at options ... After contemplating renouncing my citizenship for some time I was advised by friends to see two different lawyers downtown .I learned that the process was complicated and costly. I spent money quickly for information that was hardly worth the cost. Discouraged ,I was convinced by my accountant to retry one last time with the us tax iq. After my first interview , I realized that the process was much more simple and easy then previously advised. With Alexeys‘ help, I completed the forms and was on my way to getting things done with excellent help and much less cost. Once I completed the forms, which was far less Formation then explained in the confusing US. Website, I had my interview and was finished with the process. I wouldn’t hesitate to use this firm to help with this process and at least look at options as I know they help people who want to stay citizens. Beware of lawyers that make this way more complicated and thus expensive then it really needs to be. Leslie M.

  • Successfully renounced my US citizenship with the excellent help and advice from U.S. Tax IQ I have successfully renounced my US citizenship with the excellent help and advice from U.S. Tax IQ. I was born in the US but had lived in Canada for over 50 years as a Canadian citizen. I sought their help after finding it too cumbersome to read and understand the IRS documentation. They were very professional and knowledgeable in completing my 5 years of required taxes and FBARs and in guiding me to prepare for my Loss of Nationality appointment. Mary K
