ESY TAX GROUP REVIEWS

Eric is hands down the best CPA I’ve worked with for business. We’ve used a few from big-name firms in the past, and he actually caught their mistakes and got everything back on track for us. Super detail-oriented, incredibly responsive, and his customer service is top-notch. Always answers calls and emails. Can’t recommend him enough.

ESY Tax Group has been doing my taxes for the past several years. Eric is not only trustworthy but he is always looking to work with me and make me feel like I am not alone during sometimes the most overwhelming time of the year. He always accommodates me even for last minute requests. His expertise and good ethics every year remind me of why I always walk away from our calls feeling like I am in good hands with him.

Best tax return experience I’ve ever had! Can’t say enough good things about Eric and his team! He is extremely knowledgeable and trustworthy. He is meticulous about how he files your tax return. He pays attention to detail and was always available to answer our questions.

TAX EXPERTS OF OC REVIEWS

His professionalism and kindness made the entire process smooth and stress-free. I highly recommend Tax Experts of OC to anyone looking for a reliable and efficient tax preparer.

I would highly recommend Amin Memon CPA from the Tax Experts of OC. He did an excellent job on both of our business taxes & our personal taxes. He takes the time to explain things thoroughly and he is very knowledgeable. He came highly recommended & we will definitely be using him again next year! Thank you so much Amin! Jim & Linda Miller.

Amin is great at explaining complex tax concepts in a way that is easy to understand. He is great to work with and is very knowledgable.
