HMRC Helpline Errors Leave Taxpayers Frustrated: What’s Going Wrong?

In July 2025, HMRC came under fresh criticism after multiple reports revealed basic errors being made by its helpline staff. Despite significant recruitment efforts and major government investment, many taxpayers and agents feel that HMRC online services are still failing to deliver a high-quality service. At Apex Accountants, we’ve seen firsthand how HMRC helpline errors can cause stress, delays, and unnecessary costs for clients.

Here, we break down the latest issues at HMRC, what they mean for taxpayers, and how our team at Apex Accountants helps businesses and individuals stay compliant and well-supported in the face of growing uncertainty.

Why Is HMRC Being Criticised?

Recent reports highlight a concerning trend—helpline staff at HMRC have been accused of making basic errors when assisting callers. This includes giving incorrect advice, failing to understand technical tax queries, and causing confusion during time-sensitive situations.

A survey of taxpayers and agents found that many helpline staff lack the training and expertise to handle even standard queries. Webchat functions are often unreliable, phone calls have long wait times, and too many queries go unresolved. This leaves taxpayers frustrated and misinformed.

What Is HMRC Doing to Improve?

HMRC’s newly appointed CEO, John-Paul Marks, has shared ambitious plans to close the UK tax gap, which currently stands at £46.8 billion. HMRC CEO goal is to reduce non-compliance and make HMRC a modern, productive, and efficient organisation. Some of the steps include:

• Hiring 5,500 compliance staff by 2029-30, with 500 already in place
  
• £630 million in additional government funding
  
• Expanding the entry-level trainee programme, although it takes four years for new staff to become fully productive
  
• Boosting criminal investigations through the Counter Fraud Academy
  
• Introducing a People Strategy to improve skills, learning, and training
  

Despite these plans, many experts have raised concerns. The training timeline is long, and entry-level staff may not be able to manage complex tax issues in the short term. Until fully trained, the risk of HMRC helpline errors remains high.

Employee Engagement at HMRC Is Low

Even with the People Strategy in place, HMRC is struggling to keep its workforce engaged. The employee engagement index has not gone above 59% in the last five years and currently sits at 56%.

There have also been high staff turnover rates. Between 2024 and 2025, HMRC hired 6,408 new employees, but 5,385 left during the same period. These figures show that HMRC faces challenges in both training and retaining staff.

What Do HMRC Helpline Errors Mean for Taxpayers?

The problems at HMRC have a direct impact on taxpayers, especially those who rely on timely and accurate advice. HMRC helpline mistakes, including getting wrong answers, confusion from incorrect guidance, and unresolved issues, can result in:

• Missed tax deadlines
  
• Incorrect tax filings
  
• Penalties from HMRC
  
• Loss of time and peace of mind
  

This is where working with a professional and responsive accountant makes a real difference.

At Apex Accountants, we understand that dealing with HMRC can be overwhelming. That’s why we step in to act as your authorised agent, taking the stress off your shoulders. Here’s how we help:

1. Accurate and Timely Tax Filings

We manage all your tax deadlines—whether it’s VAT returns, corporation tax, PAYE, or self-assessments. Our team double-checks everything before submission to avoid errors and delays.

2. Dealing With HMRC on Your Behalf

You won’t have to sit on hold or chase the right person. We liaise with HMRC for you, whether it’s to resolve queries, correct issues, or track submissions.

3. Professional Representation During Disputes

5. Support with HMRC Letters and Notices

We explain what any HMRC letter means, advise on the next steps, and respond on your behalf. This avoids miscommunication and ensures things are dealt with promptly.

HMRC’s Efforts on Tax Adviser Oversight

In its annual report, HMRC also highlighted its efforts to raise standards in the tax advice market. In 2024-25, it blocked access 1,285 times to advisers who didn’t meet expectations. It also raised £1.75 million through 183 investigations into adviser tax affairs.

While this focus on quality is welcome, it places extra pressure on businesses and individuals to choose tax advisers who are fully compliant, experienced, and reliable. Engaging with a qualified and registered firm such as Apex Accountants ensures compliance with HMRC regulations at all times.

Whistleblower Compensation and Fraud Prevention

HMRC also reported a total of 164,670 tax fraud reports from the public this year. This led to the opening of 11,000 investigations, 446 of which resulted in criminal cases. The government paid £852,438 to whistleblowers whose reports helped recover tax.

These figures show that HMRC is increasing efforts to detect and penalise fraud. However, it also means that innocent taxpayers need to be extra careful about recordkeeping and tax reporting. Any discrepancy, even accidental, could lead to questioning or investigations.

At Apex Accountants, we support clients in understanding UK tax gaps, keeping clean, accurate records to avoid any red flags, and responding confidently if questions arise.

Plan To Handle HMRC Helpline Mistakes

HMRC CEO John-Paul Marks insists that HMRC has the vision, investment, and ambition needed to move forward. He says the department is committed to acting with fairness, integrity, and empathy while meeting government goals and improving taxpayer services.

However, action must now match these promises. Until then, many taxpayers remain frustrated by slow, inaccurate HMRC online services.
