    I’ve been working with Alex in Flex Tax for about eight years, using their basic $2,000 annual package, and it has been well worth it. He handles all of my tax planning, including my RMD strategy, estimated tax, ad hoc tax question better than ChatGPT or grok. I don’t like AI answers as I am getting old. and consistently helps me save over $30,000 a year. Alex is thorough, easy to work with, and always ahead of the tax rules. I trust him completely and highly recommend his services.

    I have been working with Will at Flex Tax and Consulting Group for the past few years. It has been the most stress-free experience:
    1) The process is automated and smooth from the submission of documents and explanation of the tax returns to the resolution of any complex issues (including my divorce).
    2) Will is very experienced, knowledgeable, and professional, and can address all of my questions in a timely fashion.
    3) Exception handling (from my divorce to additional analysis required by the court) is available, making it worth the cost.
    I recommend them to all my friends and family.

    I’ve worked with Flex Tax & Consulting Group for the past three years on my taxes and retirement planning. They walked me through practical retirement account options (401(k)/Solo 401(k), Traditional & Roth IRAs, and HSA where applicable), explained tax-efficient investing choices across accounts, and proactively mapped out contributions and Roth conversion timing. Their guidance led to substantial tax savings over multiple years, and they’re always clear, responsive, and detail-oriented. Highly recommend Flex Tax & Consulting Group for anyone who wants proactive planning—not just tax filing.
