EXCELLENT Based on 270 reviews Posted on Steve haywoodTrustindex verifies that the original source of the review is Google. I've used Accotax for a number of years now to complete my annual tax returns which I always find extremely stressful as I'm so disorganised and can never find important stuff. I'm consequently always last minute. This year I was worse than ever but Saad was extremely patient. He sent constant reminders to encourage me. Eventually I got the information together in my very haphazard fashion and Saad pieced it together very quickly and efficiently. I've even considered getting started on next year's figures!Posted on Eco Glitter FunTrustindex verifies that the original source of the review is Google. Have been using Accotax for over year years for my personal tax return. Muhammad Saifullah Is especially professional and helpful. Would recommmedPosted on Tom WatsonTrustindex verifies that the original source of the review is Google. Saad is patient, polite, helpful, professional and thorough. Highly recommended.Posted on pal mrTrustindex verifies that the original source of the review is Google. I honestly regret using this accounting service. What I got was a mix of incompetence, poor communication, and a complete lack of professionalism. Basic accounting tasks were mishandled, deadlines were missed, and I constantly had to follow up just to get simple answers. It felt like I knew more about my own books than the people I was paying to manage them. Mistakes were brushed off instead of corrected, and accountability was nonexistent. If you value accuracy, reliability, or peace of mind, this is not the service for you. There are far better options out there. I strongly recommend looking elsewhere before wasting your time and money.Posted on Martin SimsonTrustindex verifies that the original source of the review is Google. Waqas Sagar was very helpful. He refunded my consultation fee as we did not speak for long. The process of setting up a video appointment and connecting was seamless.Posted on Ayotunde RufaiTrustindex verifies that the original source of the review is Google. Amazing service, best accountants we've ever had. Umer is ace, and makes everything easy and transparent.Posted on Perry FarrellTrustindex verifies that the original source of the review is Google. We had Fadia at Acco Tax and she was amazing. Always went above and beyond and could always answer any questions I had. Ask for Fadia, I cant recommend her enough!Posted on Ahmed Al-QuraishiTrustindex verifies that the original source of the review is Google. This is my 1st experience working with Accotax. They are a professional, organized, and a well run team.My tax consultant Saba provided top service and undivided attention even to the slightest of details. I am glad my tax returns are handled by someone with her qualities and would like to wish her and accotax the best of luckPosted on Tony MarshTrustindex verifies that the original source of the review is Google. Fast, efficient service - responded to all my queries promptly - discussed issues directly with HMRC - given my own personal contact, Muhammad Saifullah, who was great to work with.
