I am writing to express my high regard for Hiroyuki, a CPA whom I have collaborated with for many of my bookkeeping clients over the years. My reputation and trustworthiness are paramount, directly linked to the clients I serve and the referrals I provide. In this regard, Hiroyuki has consistently proven to be dependable, helpful, and exceptionally professional. In the ever-changing landscape of tax laws and regulations, staying current in a timely manner is crucial. Hiroyuki has been a steadfast source of safety and trust for many of my clients and their businesses, navigating these continuous changes with expertise. Furthermore, as our work environment evolves and I have had the opportunity to travel and even relocate across states, technology has allowed me to continue my work while Hiroyuki seamlessly manages the needs of my clients across the U.S. It is incredibly gratifying when current or potential business opportunities provide positive feedback about a referral I've made. With Hiroyuki, I can confidently say that the system works.

Yuki and team has been preparing both my personal and business taxes for about four years now, and I don't intend on changing that. They are detailed, efficient, and knowledgable in tax laws across multiple states. All year round they are available to answer any and all questions and are flexible with setting meetings at a moments notice. This year I was a little behind compiling my tax forms, cutting it close to the deadline, but they exceeded my expectations by completing my returns with a lot of time to spare. Can't thank them enough!

Yuki helped our nonprofit with accounting consulting and he was a joy to work with! He was so patient and knowledgeable throughout the entire process that we brought him on for regular monthly consulting. Nonprofit accounting is not easy but he made it so clear for us and helped us create our financial policies and procedures. He is also filing our taxes this year. 100% recommend!

Koida Tax & Accounting has been handling my taxes for over 10 years now. I own multiple businesses and have a lot of different and unique things going on all the time that require tax research. I have sole proprietorship and LLC business structures that he supports. Hiroyuki is always available to answer questions and provide solutions to my unique tax situations. I would highly recommend his services.

â­ï¸â­ï¸â­ï¸â­ï¸â­ï¸ I can’t recommend Hiroyuki Koida, and the team at Koida Tax and Accounting highly enough! As someone with an LLC based out of state, I was feeling completely overwhelmed trying to navigate Texas tax requirements. Yuki and his team took the time to explain everything clearly, answered all my questions, and made the entire process smooth and stress-free. Thanks to their expertise, I was able to handle my out-of-state taxes confidently and correctly. If you’re running a business and need help with multi-state tax issues, this is the CPA you want in your corner!
