Case Study: Challenging a Wrongful HMRC Tax Assessment Through Civil Action

Client: Self-Employed Consultant
Area: Tax Law & Civil Litigation
Outcome: HMRC demand withdrawn, legal costs recovered

Background:
Our client, a self-employed IT consultant, received an unexpected tax bill from HMRC totalling over £48,000. The assessment claimed undeclared income and improper expense claims over a three-year period. The client insisted that their filings were accurate and feared bankruptcy if forced to pay without appeal.

Our Approach:
The London Law Firm quickly reviewed the full tax file, prior returns, and HMRC correspondence. We discovered that the assessment was based on incorrect assumptions and a miscategorised business expense structure.

We:

• Submitted a formal appeal under Section 31 of the Taxes Management Act

• Filed a parallel civil claim seeking judicial review of HMRC’s decision-making process

• Engaged tax accountants to prepare a forensic audit rebuttal

• Negotiated directly with HMRC’s legal department for early resolution

Resolution:

• The £48,000 assessment was fully withdrawn

• Our client received a written apology from HMRC

• Legal fees were reimbursed as part of the negotiated outcome

• The client’s tax records were officially corrected and updated

Client Feedback:
“I was completely blindsided by HMRC’s claim — I thought I had no chance. The London Law Firm cleared my name and saved my business.”
