A few questions about your business. Mudassir replies the same working day.
Tax investigation cover is included, free
If HMRC opens an enquiry into your business, we deal with it and you don’t pay us extra. Other firms sell this as an add-on for £300 to £1,000 a year.
Every HMRC investigation we’ve handled, we’ve won.
One client came to us owing HMRC around this much across Corporation Tax, VAT and Self Assessment, with no idea what the debts were for. We got the debt reduced and the interest written off.
Start the checkWho we work with in South Wales
Limited companies, sole traders, partnerships and CICs. Most of our clients are one of these.
Community interest companies and grant-funded organisations
Your funder wants a spend report and the accounts early for the next bid. We write quarterly and six-monthly grant reports for more than ten CICs, set up new ones, and introduce you to a fundraising consultant who finds your next grant.
Corner shops, takeaways and independent retailers
A VAT letter from HMRC, paperwork piling up behind the till, a bill you can’t make sense of. We take the paperwork as well as the accounts, and we can talk it through in Urdu or Hindi.
Serviced accommodation and rent-to-rent
Airbnb and Booking.com income across several properties, with the tax worked out before the return is due.
Any other trading business

Wales has its own rules, and we know them
He was still paying full business rates on his stores from the Covid years. Retail businesses in Wales were entitled to relief, but Cardiff Council only gave it to businesses that applied. Nobody had told him.
An accountant outside Wales may not know rules like this one. We work here, so we check for them when you join.
What clients say on Google
Thank you Mud, your help and support with my VAT return is greatly appreciated. Always a prompt response and my difficult VAT return was quickly submitted and resolved. Would definitely recommend.
I just want to say a big thank you to Mudassir for all the advice, guidance and help he has provided whilst dealing with my accounts and tax returns. From start to finish the service has been excellent and professional. Unlike other accountancy firms they provide a friendly personalised service, I was very clear on the process and was even provided with additional guidance where needed. Highly recommended!
Friendly, nice 👌 , helpful and great all around
Difficult to describe as there are too many words that can be expressed for a wonderful accountant and their firm.
Definitely 🔝 and highly recommended in Wales 🏴 and throughout the UK for Accountancy and Tax Services

I had the pleasure of working with Supreme consultants and I couldn't be more impressed with their professionalism and expertise. From the start, they took the time to thoroughly understand my financial situation and provided tailored advice that made a real difference. Their attention to detail is exceptional, and they made sure all my tax filings were accurate and submitted on time. I especially appreciated their clear communication and willingness to explain complex financial concepts in a way that was easy to understand. Thanks to Mudassir, I feel confident in my financial future. Highly recommend!
Brilliant service! Always helpful and easy to deal with. Highly recommend. Their service is indeed, supreme.
Excellent service from Supreme Consultants. The team is professional, responds quickly to client queries, and provides effective solutions. They're reliable, knowledgeable, and always helpful. Highly recommend their accounting services!
Finally, I got a professional guy and he done a great job, and I'm really satisfied. 100% recommended. Best in town
How switching to us works
We write to your current accountant for the handover, so you don’t have to make that call.
Week one
We check your ID, agree your fixed fee in writing and ask your current accountant for your records. HMRC and Companies House authorise us as your agent.
First month
We go through your past accounts, returns and HMRC records. This is where unclaimed reliefs and penalties worth appealing turn up.
By ninety days
We sit down with you on how you pay yourself and every deadline in the year ahead. From then on you call us when you need us.
