I have been filing tax returns with AOTax for last 10+ years. Prashanth Chalki has been super helpful, knowledgeable, has a lot of patients to respond to all the queries & above all a wonderful person to interact. He has made my tax filing experience above & beyond.

Hi, I recently worked with Mr. Ali Khan from AOTAX for my tax drafting, and I had a very positive experience. He was patient, interactive, and took the time to clear all my doubts to the best of his knowledge. His communication made the whole process much easier for me. I’ve been using AOTAX for the past year, and they have consistently supported me — especially when I received an audit notice. Their team guided me through the process and helped resolve the issue smoothly. Although their electronic filing system had a small flaw during my submission last year , they handled the situation well and recovered their service through effective service recovery. Overall, I appreciate their support and professionalism, and I’m satisfied with the assistance I received.

I am very happy with the AOTAX services. Support representative Yedla Vineeth was very helpful in explaining each and every line item in the Tax Draft and was very thorough with the Tax Line items explanation. I will recommend AOTAX to everyone.
