I worked with Accotx on a HMRC reclaim and overall, they did ultimately deliver on their promise, which I appreciate. The process did take longer than any of us expected, partly due to external delays with the tax authorities, and partly because there were some hiccups in communication and follow-up. However, despite those challenges, they stayed professional and stuck to the original agreed terms. If you’re considering using them, be prepared to stay in regular contact to keep things moving along. They are absolutely capable, have the expertise and willing to work with you, and overall improving their services over time. I would certainly return for any future needs.Posted on Google![]()

I highly recommend Imran to anyone looking for a reliable and knowledgeable accountant. He helped me sort out a very complicated backlog of accounts and prepared my overdue tax returns with professionalism and attention to detail. Throughout the process, he was incredibly patient, took the time to answer all of my questions, and explained everything clearly. He guided me through each step and helped rectify issues that had built up over time, making what felt like an overwhelming situation much more manageable. I'm very pleased with the service I've received and truly appreciate his support. If you need help with your accounts or taxes, I would highly recommend Imran.Posted on Google![]()

We worked with a few different accountants before finally settling with Accotax, and we’re really glad we did. Their team is great. Abdul is responsive and easy to reach whenever I have a question, which makes a big difference. They take the time to understand how our business works and what our needs are. They are very knowledgeable, and when they don’t have the answer straight away, they take the time to look into it and get back to us quickly. Anum, who looks after our account on a day-to-day basis, including reconciling invoices and preparing the annual accounts, is amazing. She is professional, efficient, and follows the processes we have put in place together. She's also very quickin getting back to us whenever needed. We’re very happy to work with her and hope to continue doing so for as long as possible. Overall, Accotax has made our accounting experience much smoother and easier. We see them as a long-term partner as our business continues to grow. I would 100% recommend them.
