Escalating a Complaint within HMRC

After initiating a complaint through one of the methods described in the first part of our guide, if you find the resolution from the first tier review unsatisfactory, you can escalate the complaint to ensure further examination and possible rectification. This second part of our guide focuses on the escalation process within HMRC, detailing how to proceed to the second tier review and the involvement of the Adjudicator’s Office if needed.

Second Tier Review

If the outcome of the initial review does not resolve your complaint to your satisfaction, you have the right to request a second tier review. This review is handled by a different officer from the one who conducted the initial review to ensure impartiality and a fresh examination of the issues raised.

  1. Requesting a Second Tier Review: To initiate this review, you must formally request it by outlining why the first tier resolution was inadequate and what further actions you believe HMRC should take. This must be done within a specific timeframe, usually within 30 days of the first tier review decision.

  2. Process and Expectations: During the second tier review, HMRC re-examines the complaint, potentially asking for additional information and re-evaluating the circumstances and evidence. The reviewing officer will then provide a new decision, aiming to resolve the issue more satisfactorily.

Involvement of the Adjudicator’s Office

If, after the second tier review, the complaint remains unresolved or you are dissatisfied with the handling or outcome, you can take your complaint to the Adjudicator’s Office, which acts as an independent body to review complaints about HMRC.

  1. Eligibility for Review: Before approaching the Adjudicator, you must have completed both the first and second tier reviews within HMRC. The Adjudicator's Office will consider complaints that involve issues such as unfair treatment, mistakes in procedure, or inappropriate actions taken by HMRC staff.

  2. How to File a Complaint to the Adjudicator: You need to submit a complaint in writing, outlining the history of your complaint, the reviews already completed by HMRC, and why you believe the issue is still unresolved. This must be done within six months after the final decision by HMRC unless there are exceptional circumstances delaying your submission.

  3. What the Adjudicator's Office Does: The Adjudicator’s Office reviews the procedures followed by HMRC and the application of the laws or policies relevant to your case. They assess whether HMRC has treated you fairly and within the bounds of their legal and policy frameworks.

Possible Outcomes

The outcomes from the Adjudicator’s Office can include:

  • Confirmation that HMRC handled your complaint appropriately.

  • Recommendations for HMRC to take additional actions to correct their mistakes or to offer compensation if applicable.

  • In some cases, a recommendation for more systemic changes within HMRC if your complaint highlights broader issues with their processes or policies.

Next Steps After the Adjudicator's Review

If the Adjudicator’s Office does not resolve your complaint to your satisfaction, you have the option to escalate the matter further by involving your Member of Parliament or even pursuing a judicial review for legal examination of HMRC’s actions, although this is a more complex and potentially costly route.

External Escalation and Judicial Review

After exhausting all internal avenues with HMRC and the Adjudicator’s Office, if your complaint remains unresolved or you believe the decisions made are fundamentally flawed, there are external escalation paths you can pursue. This final part of our guide delves into the procedures for escalating a complaint through parliamentary channels and the potential for judicial review.

Parliamentary Involvement

Referral to the Parliamentary Ombudsman:

If the Adjudicator’s Office is unable to resolve your complaint, or if you disagree with their findings, you can ask your Member of Parliament (MP) to refer your case to the Parliamentary and Health Service Ombudsman. This Ombudsman can investigate complaints about most government departments and agencies, including HMRC.

  • Process: You must first contact your MP, explain your situation, and provide all relevant documents related to your complaint. Your MP will then decide whether to forward your complaint to the Ombudsman.

  • Role of the Ombudsman: The Ombudsman examines the case from the perspective of whether there was administrative fault, such as service failure or maladministration, and can recommend remedies including apologies, changes in procedure, or financial compensation.

Judicial Review

Considering Judicial Review:

As a last resort, you might consider a judicial review, a type of court proceeding where a judge reviews the lawfulness of a decision or action made by a public body. In the context of HMRC, this could relate to decisions perceived as illegal, irrational, or procedurally improper.

  • Eligibility: Judicial review is appropriate only when no other appeals or remedies are available. It's not about disagreeing with a decision because it's wrong, but rather because it was made in a legally flawed way.

  • Process: Filing for judicial review involves submitting a claim to the High Court, which must be done promptly—usually within three months of the decision you are challenging.

Financial and Legal Considerations:

Judicial review can be expensive and complex, often requiring expert legal advice and representation. Before proceeding, it's crucial to consult with a solicitor who specializes in administrative law and possibly seek legal aid if eligible.

Practical Advice and Resources

  • Seek Professional Advice: Given the complexity of HMRC complaints, especially at the stages of parliamentary involvement and judicial review, obtaining advice from tax professionals or legal experts is highly advisable.

  • Maintain Comprehensive Records: Throughout the complaints process, keep detailed records of all correspondence, decisions, and actions taken. This documentation will be invaluable during external escalation and legal proceedings.

  • Be Aware of Deadlines: Always be aware of the deadlines for each stage of the complaint process, from HMRC internal reviews to external appeals like judicial reviews.

Navigating the HMRC complaints process can be daunting, especially when standard remedies do not resolve the issue. By understanding the full scope of options—from initial complaint through to judicial review—you are better equipped to seek justice and resolution. Remember, while the process can be lengthy and demanding, numerous resources and professionals can offer guidance and support.

Overview and Methods for Common HMRC Complaints

Overview and Methods for Common HMRC Complaints

When dealing with Her Majesty's Revenue and Customs (HMRC), UK taxpayers may find various reasons to lodge a complaint ranging from service delays to procedural errors. Understanding the types of complaints commonly made to HMRC and the appropriate methods to address them is crucial for efficient resolution. This article will outline the common categories of complaints and guide taxpayers on how to effectively initiate these complaints.

Types of HMRC Complaints

  1. Service Delays: One of the most frequent complaints concerns delays in services, such as the processing of tax returns, refunds, or responses to queries.

  2. Incorrect Processing: Taxpayers may encounter errors in the processing of their tax documents, leading to incorrect tax calculations or misapplied codes.

  3. Poor Customer Service: This includes rude or unhelpful interactions with HMRC staff, often prompting complaints about the professionalism or conduct of personnel.

  4. Misinformation: Providing incorrect or misleading information, whether on HMRC's website or through direct communication, can lead to significant inconveniences for taxpayers.

  5. System Errors: Technical issues with HMRC's online services, which can prevent taxpayers from fulfilling their obligations or accessing necessary information.

Appropriate Methods for Filing Complaints

Each type of complaint may require a slightly different approach to ensure it is addressed effectively:

  1. Online Complaints: The most direct and convenient way to file a complaint is through the HMRC online portal. This platform allows individuals, businesses, and agents to submit complaints directly. To access these services, users need to sign in with their Government Gateway user ID, which can be created during the process if not already possessed.

  2. Telephone Complaints: HMRC offers specific contact numbers for different types of services, such as tax credits, VAT, customs, and National Insurance. Taxpayers should use these dedicated lines to address specific issues related to each department. It's crucial to have all relevant information handy, such as National Insurance numbers and details of the complaint, to facilitate a quick resolution.

  3. Postal Complaints: For those preferring or requiring a written record, HMRC accepts complaints via post. Taxpayers should clearly mark their letters as 'complaints' and include all necessary details such as their reference numbers and a full account of the issue. This method is often used for formal complaints, especially when detailed documentation needs to be reviewed.

  4. Specialist Lines and Additional Support: HMRC provides additional support for complaints involving more complex issues, like tax fraud or serious misconduct by HMRC staff. These require more specialized handling to ensure they are addressed appropriately.

What Happens After You Complain?

Once a complaint is lodged, HMRC initiates a tiered review process. The first tier involves a basic review of the complaint details and an attempt to resolve it immediately. If the outcome is unsatisfactory, the complaint can escalate to a second tier review, where another officer re-evaluates the case. Should resolution still not be reached, the Independent Adjudicator’s Office may review the complaint. Finally, unresolved complaints can be taken to the Parliamentary and Health Service Ombudsman via a Member of Parliament.

Detailed Procedures for Specific HMRC Complaints

Building upon the initial discussion of how to lodge complaints against HMRC, this section dives deeper into the specific procedures for various types of complaints. Understanding these nuances can empower taxpayers to effectively navigate the complexities of HMRC's complaint resolution process, ensuring that their issues are addressed with the appropriate level of scrutiny and urgency.

Detailed Complaint Procedures Based on Type

  1. Tax Code Errors and Overpayments: Discrepancies in tax codes or apparent overpayments require a detailed submission, often necessitating supporting documents like P60s, payslips, and communication records with HMRC. Taxpayers should initiate these complaints through the online portal for accuracy and speed but can follow up via telephone if immediate clarification or adjustment is necessary.

  2. Delayed Refunds: When expecting a refund that hasn't been processed within the standard timeframe, taxpayers should first check the status through their online account. If no satisfactory information is available, a direct inquiry via HMRC's dedicated hotline for refund issues is advisable. Documenting all interactions provides a timeline that can be useful if the complaint needs escalation.

  3. Misinformation Provided by HMRC: If erroneous advice or information from HMRC leads to financial loss or filing errors, it's crucial to provide specific details about the interaction, including dates, names, and the nature of the misinformation. This type of complaint might benefit from additional written correspondence to ensure a formal review of the case.

  4. Technical Issues with HMRC Online Services: For complaints regarding online services, such as system outages or errors during submission processes, taxpayers should use the specific online service complaint form. Capturing screenshots and detailing the exact nature of the technical issue can help technical support teams resolve the issue more efficiently.

  5. Complaints About HMRC Staff or Service: When service received from HMRC staff is below expected standards, recording the date, time, and details of the interaction helps substantiate the complaint. These complaints can be submitted online but might also be followed up by a letter if the issue involves complex interactions or multiple instances of poor service.

Escalation Process for Unresolved Complaints

If a complaint is not resolved to the taxpayer's satisfaction through the standard channels, the following escalation process can be employed:

  1. Tier 2 Review: If the initial response is inadequate, requesting a Tier 2 review involves a more senior HMRC staff member re-evaluating the complaint details and the initial decision.

  2. Adjudicator’s Office: For unresolved complaints after a Tier 2 review, the next step is to appeal to the Independent Adjudicator's Office. This body looks into the fairness and appropriateness of HMRC's actions in handling the complaint.

  3. Parliamentary and Health Service Ombudsman: As a final resort, complaints that remain unresolved after review by the Adjudicator’s Office can be taken to the Ombudsman through a Member of Parliament. This step requires substantial documentation as proof of the grievance and the inadequacy of previous resolutions.

Tips for Effective Complaint Handling

  • Keep Detailed Records: Always keep detailed records of all communications with HMRC, including dates, times, names, and the content of interactions.

  • Be Clear and Concise: When describing the issue in a complaint, be clear and concise. Provide all relevant details but avoid unnecessary complexity.

  • Understand the Process: Familiarize yourself with HMRC’s complaint process, including timeframes for responses and escalation procedures.

This comprehensive approach to handling specific complaints with HMRC not only streamlines the process but also increases the likelihood of a favorable resolution. In the next part, we will explore case studies that illustrate successful complaint resolutions and offer further insights into navigating HMRC's complaint system effectively.

Case Study: Alice Bennett's HMRC Complaint Journey

Alice Bennett, a freelance graphic designer from Leeds, found herself paying more in her self-assessment tax than she should have. In early 2024, Alice realized that her tax calculations did not account for her newly eligible tax deductions and an incorrect tax code applied by HMRC. This error resulted in an overpayment of £2,500 in her self-assessment tax for the 2023-2024 tax year.

Background and Initial Steps

Alice's troubles began when she did not notice the shift in income thresholds for the self-assessment introduced in April 2024, which raised the limit from £100,000 to £150,000. This change should have exempted her from certain deductions due to her income level, which hovered around £145,000, inflated this year by an unusual large project completion. Additionally, due to HMRC's system error, her tax code was incorrect, reflecting an outdated state rather than her current earnings and deductions. Recognizing these discrepancies, Alice decided to take action by leveraging her rights to rectify these errors and reclaim her overpayment.

Online Complaint Submission

Her first step was to log into her HMRC online account using her Government Gateway ID, which she already had set up. For users without an ID, the system prompts them to create one, requiring information like National Insurance number and a valid UK passport or driving licence for identity verification.

Upon accessing her account, Alice navigated to the complaint section and submitted a detailed complaint online. She included specific details of her issue—incorrect tax code and failure to update her income threshold. She attached relevant documents such as her P60, payslips, and a detailed calculation of what her tax assessment should have been versus what was charged.

The Complaint Handling Process

After submitting her complaint, the process followed HMRC's standard protocol for handling such cases. Initially, her complaint was reviewed at the 'first tier' level, where basic issues are typically resolved. Unfortunately, Alice's case was complex, involving both a system error and a tax code misclassification, requiring it to be escalated to a 'second tier' review for a more thorough investigation.

During this review, a different HMRC officer reassigned her the correct tax code and adjusted her income threshold status in the system. This action was taken after a comprehensive review of her submitted evidence and recalculating her tax liabilities.

Resolution and Refund

Within three weeks of her second-tier review submission, Alice received communication from HMRC acknowledging the mistake and confirming the rectification of her tax code and income threshold. They issued a refund of the overpaid £2,500, which was processed back into her bank account within another two weeks.

Alice also applied for compensation for the time value of money lost due to the overpayment, which HMRC approved under their policy to refund reasonable costs directly caused by their errors, including professional fees, if applicable.

Key Takeaways

This hypothetical scenario underscores the importance of taxpayers keeping informed about tax law changes and reviewing their tax assessments diligently. Alice's proactive steps in managing her tax complaint through HMRC's structured complaint process not only corrected the immediate fiscal discrepancies but also ensured that similar issues would be less likely in future assessments.

For anyone dealing with similar issues, it's crucial to document all communications, keep detailed financial records, and understand the pathways for raising concerns with HMRC, including the use of online platforms, phone calls, or postal methods for those preferring or requiring a physical record of their complaint.

How Can a Personal Tax Accountant Help You Make a Complaint to HMRC

How Can a Personal Tax Accountant Help You Make a Complaint to HMRC?

Engaging a personal tax accountant can be a transformative decision, especially when dealing with complex issues like making a complaint to Her Majesty's Revenue and Customs (HMRC) in the UK. This specialized professional can guide you through the intricacies of the tax system, ensuring that your complaint is not only heard but also acted upon efficiently and effectively. Here’s a detailed breakdown of how a personal tax accountant can assist you in this process:

Expertise in Tax Law and HMRC Policy

A personal tax accountant brings a deep understanding of tax laws and HMRC policies, which is crucial when framing a complaint. They are adept at identifying errors that may have been overlooked, such as incorrect tax calculations, misapplied tax codes, or failures in procedural compliance by HMRC. Their expertise allows them to articulate the issues clearly and authoritatively in the language that resonates with HMRC officials, increasing the likelihood of a favorable outcome.

Document Preparation and Management

Filing a complaint with HMRC requires meticulous documentation. A tax accountant can help gather, organize, and present all necessary documentation to support your case. This includes compiling tax returns, financial statements, previous correspondence with HMRC, and any other relevant documents. Accurate and comprehensive documentation is key to substantiating your complaint, and a tax accountant ensures that all paperwork is in order, which can significantly streamline the complaint process.

Representation and Communication

Communicating with HMRC can be daunting for individuals who are not familiar with tax jargon or the nuances of tax law. A personal tax accountant can act as your representative, handling all communications with HMRC. This includes writing letters, making phone calls, or submitting forms through HMRC’s online portals. Their ability to communicate effectively with HMRC can help clarify issues, negotiate solutions, and push for a timely review of your complaint.

Strategic Advice and Planning

A tax accountant can provide strategic advice on the best course of action based on the specifics of your complaint. This might involve advising on whether to escalate the complaint to higher authorities within HMRC, such as the Adjudicator’s Office or the Parliamentary and Health Service Ombudsman, if initial responses are unsatisfactory. They can also help plan a long-term strategy, especially if the complaint involves potential legal proceedings or adjustments to your tax strategy.

Stress Reduction and Time Management

Dealing with tax issues can be stressful and time-consuming. Employing a tax accountant alleviates the stress associated with navigating the complex bureaucracy of HMRC. They handle the burden of the complaint process, allowing you to focus on your personal and professional life without the added anxiety of tax disputes. Moreover, tax accountants can expedite the complaint process by ensuring that all submissions are correct and complete the first time, potentially reducing the time it takes for HMRC to respond.

Financial Analysis and Implications

A tax accountant can analyze how the outcome of a complaint might affect your overall financial situation. This includes calculating potential refunds, additional taxes owed, or the financial impact of any changes to your tax record. Such financial insights are invaluable, ensuring that you are fully informed about the potential consequences of your complaint.

Preventative Measures and Future Guidance

Finally, beyond addressing the immediate complaint, a tax accountant can provide guidance on how to avoid future issues with HMRC. They can offer advice on proper record-keeping, tax planning, and compliance, thus minimizing the likelihood of future disputes. This proactive approach not only helps in current resolution but also fortifies your financial dealings against potential future problems.

A personal tax accountant is not just a facilitator for dealing with HMRC complaints but a strategic ally who adds substantial value throughout the process. Their involvement ensures that your complaint is presented effectively, handled professionally, and resolved in a manner that aligns with your best financial interests.
