ABOUT THE TAX SOLICITOR

I am Koyes Uddin, a Tax Disputes Solicitor specialising in high stakes HMRC investigations and litigation. After a decade inside HMRC’s Solicitor’s Office and a mid sized law firm, I know precisely how HMRC builds cases, where their arguments are vulnerable, and how to dismantle them. That insight shapes every strategy I deploy. When clients instruct me, they gain a litigator who anticipates HMRC’s next move and responds with decisive, legally grounded action.

I represent business owners, high net worth individuals and professionals facing aggressive or complex tax challenges. Whether I'm dealing with COP8/COP9, personal liability and security notices, tax avoidance allegations or Tribunal appeals, I take control of the dispute from day one.
My approach is direct: shut down unnecessary HMRC pressure, challenge flawed assumptions, and hold HMRC strictly to the law. I focus on securing outcomes that protect my clients’ position and keep HMRC firmly within its statutory limits.
