The yprovide an excellent value for money service. Umer demonstrates strong technical knowledge across accounting and tax compliance, combined with a practical, commercial approach. Matters are handled accurately, efficiently, and with clear explanations, which is particularly valuable when dealing with complex or multi-layered requirements.

The combination of Umer’s technical competence and the firm’s operational discipline results in a dependable, professional service that gives confidence in both compliance and advisory outcomes. I would readily recommend Umer and Accotax to businesses or individuals seeking a technically sound, well-managed accounting and tax advisory practice.Posted on JD Skills SchoolTrustindex verifies that the original source of the review is Google. We have been working with Fadia for over two years now and she is very professional and pleasant to work with. She takes time to make time to explain in detail all aspect of our yearly accounts. I’d would highly recommend Fadia for any business that require professional accounts.Posted on Roz LawsonTrustindex verifies that the original source of the review is Google. Great service - Fadia handled my personal tax return very efficiently, and explained everything clearly - and I got a repayment from HMRC!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!

Common Mistakes Sole Traders Make on Tax Returns
Filing a Self Assessment tax return as a sole trader can be straightforward, but small errors can lead to HMRC penalties, fines, or missed tax-saving opportunities. Many sole traders underestimate the complexity of tax rules, allowable expenses, and deadlines, which can result in overpaying tax or triggering audits.
Failing to Record All Income Accurately
Not reporting all sources of income, including side jobs or cash payments, can trigger penalties and underpayment charges from HMRC.
Missing Out on Allowable Expenses
Sole traders often overlook deductible business costs, such as travel, equipment, or professional fees, which could legally reduce taxable income.
Late Filing and Payment of Taxes
Submitting tax returns or paying the tax bill after deadlines can lead to automatic fines, daily penalties, and interest charges, increasing your overall liability.
