How to Challenge and Appeal a Benefit Decision by HMRC in the UK: A Step by Step Guide

Updated: Mar 20

Challenging and appealing a decision made by HM Revenue and Customs (HMRC) or the Department for Work and Pensions (DWP) regarding benefits can appear complex and intimidating. However, with a clear understanding of the process and thorough preparation, you can significantly improve your chances of achieving a favorable outcome. This detailed guide, updated for 2024, walks you through each step necessary to confidently address any disputes with your benefit decision, ensuring you are fully prepared to navigate through the appeals process.

How to Challenge and Appeal a Benefit Decision by HMRC in the UK: A Step by Step Guide

Understanding Eligibility and Initial Steps

Before embarking on the appeals process, it's vital to determine if your case qualifies for reconsideration. Eligibility to challenge a decision encompasses errors, overlooked evidence, or disagreements with the decision's rationale, pertaining to benefits, tax credits, or child maintenance. It's important to note that not all decisions are eligible for reconsideration; some may require a direct appeal, as indicated in the decision letter.

The window for requesting a "mandatory reconsideration," the preliminary step in disputing a decision, is typically one month from the decision date. Extensions may be granted under specific circumstances, such as hospitalization or bereavement. This procedure applies to a wide array of benefits, including Attendance Allowance, Carer's Allowance, Universal Credit, and many others. Separate processes exist for Child Benefit, Tax-Free Childcare, and tax credits.

Seeking Support and Advice

Securing support and advice before challenging a decision is highly recommended. Organizations like Citizens Advice and local welfare rights groups offer free resources, providing crucial guidance to understand your case's nuances and potential legal intricacies.

The Mandatory Reconsideration Process

To initiate a mandatory reconsideration, contact HMRC or DWP directly, using the contact information provided in your decision letter. It's crucial to clearly articulate why the decision is believed to be incorrect and to supply any supplementary evidence to bolster your case.

Following your request, you will receive a Mandatory Reconsideration Notice, detailing HMRC's or DWP's revised decision. Should you disagree with this revised decision, the notice will inform you whether an appeal to an independent tribunal is permissible.

Timing is Crucial

Adhering to designated timelines is critical. While the general rule is a one-month window from receiving your decision to request a mandatory reconsideration, appealing a tax credit decision without an extension follows a different timeline.

This section of our comprehensive guide has outlined the essential initial steps in challenging and appealing a benefit decision in the UK, focusing on eligibility, seeking advice, and the mandatory reconsideration process. Subsequent sections will delve into the appeal process and offer additional guidance on effectively managing these proceedings.

Preparing for the Appeal

If you receive confirmation through your mandatory reconsideration notice that an appeal is viable, the next step is meticulous preparation for the appeal process, handled by the Social Security and Child Support Tribunal, independent of HMRC and DWP.

1. Filing an Appeal

Initiate the appeal through direct lodgement to the tribunal. Appeals should be filed within a month from the mandatory reconsideration notice date, though exceptions exist for specific circumstances, like postal delays or personal health issues.

For DWP decisions, appeals can be submitted online via the GOV.UK website or by completing and mailing form SSCS1. For HMRC decisions, particularly tax credits, form SSCS5 is necessary. Both forms require a copy of your mandatory reconsideration notice.

2. The Appeal Hearing

When filing your appeal, you'll decide if you wish for a hearing. Choosing a hearing can increase your success chances, allowing you to verbally present your case. It's important to communicate any special requirements for the hearing at this stage.

A tribunal judge, sometimes accompanied by a panel, will review your case during the hearing. Although less formal than court proceedings, clear presentation and comprehensive evidence are paramount.

3. Submitting Evidence

All evidence previously provided to HMRC or DWP will be forwarded to the tribunal; however, you must submit any new evidence directly. Collect as much supportive documentation as possible, including medical reports, financial statements, or professional support letters.

What If You Miss the Appeal Deadline?

Missing the one-month appeal filing deadline still allows for the possibility of submitting a late appeal, provided a valid reason for the delay is given. The tribunal may accept appeals up to 13 months after the decision date, albeit without guarantee.

After the Tribunal Decision

A favorable tribunal decision mandates HMRC or DWP to execute the decision. If the outcome is not as expected, further appeal options exist, including appealing to the Upper Tribunal for perceived legal errors in the decision-making process.

Navigating the appeal of a benefit decision involves a structured, detailed process demanding attention to detail and timely actions. From initiating your appeal to presenting your case at a hearing, each stage presents an opportunity to effectively argue your position. The concluding part of this guide will explore post-tribunal decision scenarios, including further appeals and managing the outcome, ensuring you are fully informed to exercise your rights and receive the support.

Receiving the Tribunal's Decision: Navigating the Next Steps

After a tribunal renders its decision on a benefit appeal in the UK, both the appellant and either HMRC or DWP are issued a written notice detailing the judgment. Should the decision favor the appellant, the concerned department is mandated to adjust the appellant's benefits as per the tribunal's ruling swiftly.

Understanding the Tribunal's Decision

Post-hearing, the tribunal dispatches a written decision to the parties involved. This document elucidates the rationale behind the tribunal's verdict on the appeal. A favorable decision prompts HMRC to adjust your benefits or reassess your eligibility based on the tribunal's conclusions.

If the Decision Favors You

HMRC's Obligation: HMRC is obliged to enact the tribunal's decision, potentially recalculating your benefit entitlement or issuing back payments for any underpaid periods.

Follow-up Actions: It's crucial to ensure HMRC complies with the tribunal's ruling. Should you encounter delays or issues, contacting HMRC directly or seeking additional advice might be necessary.

When the Decision is Against You

An unfavorable tribunal decision isn't necessarily the end. You can contest the tribunal's verdict under specific conditions.

Set Aside Requests: If procedural errors occurred, or new evidence has surfaced that wasn't available at the initial hearing, you might request to have the decision set aside. This action temporarily nullifies the tribunal's decision, possibly leading to a new hearing.

Upper Tribunal Appeals: Should you discern a legal mistake in the First-tier Tribunal's decision, an appeal to the Upper Tribunal (Administrative Appeals Chamber) is an option. This appeal focuses on the legal basis of the decision rather than the decision itself. Given the complexity, seeking legal advice is highly advised.

Seeking Legal Aid and Support

For those contemplating an Upper Tribunal appeal, exploring legal aid eligibility can offer necessary financial assistance, covering legal advice, representation, and court fees. Various organizations, including Citizens Advice and local legal aid clinics, can guide eligibility and application processes.

Coping with the Outcome

Regardless of the tribunal's decision, navigating a benefit challenge can be stressful. It's essential to seek support from friends, family, or professional counseling services. Financial advice services can also provide practical support in managing your finances throughout and after the dispute process.

Challenging and appealing a benefit decision in the UK entails a detailed and potentially prolonged process. From mandatory reconsideration to possible Upper Tribunal appeals, each phase demands meticulous preparation and informed decision-making. Staying informed, seeking professional advice, and compiling supportive evidence are key. Remember, support is available to assist you through this challenging journey.

HMRC Forms for Appealing a Benefit Decision

In the UK, contesting a benefit or tax credit decision starts with a mandatory reconsideration by HMRC, followed by an appeal if necessary. Knowing which forms to use and how to submit them correctly is crucial for an efficient appeal process.

Mandatory Reconsideration as the First Step:

Requesting a mandatory reconsideration from HMRC is the first required step. This reconsideration must be requested within one month of the original decision. The form or method to request varies based on the specific benefit.

  • For Tax Credits and Child Benefit: The challenge can begin online or by using form WTC/AP for tax credits decisions. It's recommended to submit this request in writing, keeping a copy for records. For postal submissions, obtaining proof of postage is advisable. You need to send the postal form to: HMRC Preston, BX9 1ER

  • For Other HMRC-related Benefits: Appeals concerning benefits like Child Benefit (excluding tax credits) or Guardian's Allowance might require forms like CH24A, with specific guidelines for each benefit type.

Appealing to the Tribunal:

Should HMRC maintain its stance post-mandatory reconsideration, appealing to an independent tribunal becomes the next step, using Form SSCS5.

  • Form SSCS5: This form is critical for appealing against HMRC decisions about benefits, including tax credits and child benefits. Completing the form correctly requires closely following the accompanying guidance (SSCS5A), ensuring all required information and documentation are accurately provided.

  • Submission Timeline: Appeals must be lodged within a month of receiving the mandatory reconsideration notice. Late submissions must be justified, and acceptance is not guaranteed.

  • Supporting Documentation: Including relevant information and attaching supporting documents, such as new evidence or detailed explanations, is essential when submitting forms for either mandatory reconsideration or an appeal.

  • Submission Methods: Forms can be submitted online, by post, or, in some instances, over the phone. Use the correct method for your appeal type, and consider secure delivery methods for postal submissions.

  • Getting Help and Advice: The appeals process can be daunting. Free assistance and advice are available from Citizens Advice, MoneyHelper, and the Low Incomes Tax Reform Group (LITRG), offering support on form filling, evidence inclusion, and understanding the appeals process, ensuring you're well-prepared for each step of your appeal.

Filing Form SSCS5: A Comprehensive Guide

Sections 7 & 8: Hearing Support and Availability

Indicate any support needs for the hearing and your availability, aiming for flexibility to minimize delays.

Section 9: Signature and Submission

Sign the form to confirm the information’s accuracy and include the MRN or original decision notice when mailing to the HM Courts & Tribunals Service.

Additional Tips

  • Evidence Submission: Submitting supporting evidence, though not mandatory, can strengthen your appeal, including documents that underscore your reasons for appealing.

  • Online Management: Providing contact details for online updates can streamline communication about your case.

  • Privacy Concerns: Clearly request confidentiality for your address if needed, especially in sensitive cases.

A Hypothetical Case Study: Navigating a Benefits Appeal with HMRC

In this hypothetical scenario, we examine the journey of Alex, a freelance software developer from Manchester, as he navigates the process of challenging and appealing a benefits decision by HMRC in the UK, particularly focusing on the use of the SSCS5 form for his appeal. This case study is enriched with specific financial details and calculations to shed light on the complexities of disputing a benefits decision.


Alex, with an annual self-employment income of £30,000, encountered a discrepancy after HMRC reviewed his benefits. After accounting for £9,000 in legitimate business expenses, his net income was £21,000. However, HMRC ceased his benefits, mistakenly ignoring these expenses and not considering a three-month period of illness which further reduced his income.

Step 1: Mandatory Reconsideration Request

After the adverse decision from HMRC, Alex compiled his financial records, showing a gross income of £30,000 but, due to £9,000 in business expenses (including software subscriptions, home office utilities, and professional development costs) and a £4,000 decrease in earnings due to illness, his actual income was significantly lower.

Despite presenting this evidence, HMRC upheld their original decision during the mandatory reconsideration phase, inaccurately basing their calculations on the gross income of £30,000, thereby affecting his benefits eligibility.

Step 2: Filing an Appeal

Undeterred, Alex prepared his appeal using the SSCS5 form, highlighting the incorrect income calculation. He detailed his actual net income of £21,000, which was further reduced to £17,000 because of his health-related work interruption. He attached all relevant financial documentation and medical evidence to support his claim.

The Tribunal Hearing

At the tribunal, Alex was given the opportunity to elaborate on his financial situation:

  • Gross income: £30,000

  • Business expenses: £9,000 (breakdown: £3,000 on software subscriptions, £2,000 on utilities for his home office, £4,000 on professional development)

  • Net income before illness: £21,000

  • Reduced income due to illness: £4,000

  • Final adjusted net income: £17,000

He argued that his eligibility for Working Tax Credits should be based on the adjusted net income of £17,000, contrary to HMRC's calculation based on his gross income.

Decision and Outcome

Upon reviewing the detailed evidence and Alex's testimony, the tribunal identified the miscalculation by HMRC. They acknowledged the genuine business expenses and the temporary reduction in Alex's income due to illness. The tribunal ruled in Alex's favor, directing HMRC to recalculate his Working Tax Credits based on the adjusted net income of £17,000.


Alex's hypothetical case emphasizes the importance of maintaining accurate financial records and the necessity of articulating one’s circumstances clearly in the appeal process. His diligent preparation and detailed explanation of his income fluctuations and business expenses were pivotal in achieving a favorable resolution.

This case study illustrates the complexities involved in appealing a benefits decision with HMRC and highlights the critical role of thorough documentation, effective communication, and perseverance in navigating the UK’s benefits appeals process.
