For more detailed guidance, you may consult legal experts or refer to employment law resources.


Acas Early Conciliation Certificate

Before filling out an ET1 Form, nearly everyone should have an Acas early conciliation certificate number. Acas (Advisory, Conciliation and Arbitration Service) is an organization that provides free and impartial advice to employers and employees. The certificate number is a prerequisite for proceeding with the tribunal claim.


Special Circumstances

The form also includes sections for multiple cases, where your claim might be one among several against the same employer. It also allows for the inclusion of additional respondents, beyond the primary employer, who might be part of the claim.


What Happens When You Submit an ET1?

Once you've submitted your ET1 form, the tribunal will send a copy of the form to your employer. Your employer will then have 28 days to respond to your claim by submitting an ET3 form. The ET3 form is the employer's response to your claim and sets out their position on the allegations you've made.



After the employer has responded, the tribunal will set a date for a preliminary hearing. The purpose of the preliminary hearing is to clarify the issues in dispute and to identify the evidence that will be presented at the full hearing. The full hearing is usually held within three to six months of the preliminary hearing. At the full hearing, both parties will present their evidence and arguments to the tribunal, and the tribunal will make a decision on the case.


How Long Do I Have to Submit an ET1?

Depending on the nature of the complaint, there are time limits for filing lawsuits in court. For example, the ET1 for a wrongful dismissal request must normally be filed within 3 months minus 1 day from the date of termination of employment. Given the importance of the ET1, we encourage you to base your case on a professionally designed ET1 form.


Filling out your ET1 form is undoubtedly stressful. In addition, you have to meet strict deadlines. As a general rule, you have 3 months less than 1 day from the date of the disputed act or the last date of employment to file a complaint with the labor court. ACAS has the authority to freeze the time limit during an early arbitration. Calculating deadlines can be complicated and depends on your specific circumstances. You should be careful as it is very unlikely that you will be able to claim if the ET1 is not received on time.


When Completing the ET1 form, You Must Ensure the Following:

Provide a clear but detailed list of events - Keep to the point as much as possible, but make sure you convey all the important details.

Keep Things Orderly - When listing events, be sure to keep them in chronological order.

● Number the paragraphs - Many wouldn't consider this, but this will make it easier to find and refer to parts of your complaints in the future.

Write down any significant events in your dispute – It can be difficult to add in the future, so write down any events that you want to rely on.

Are you naming the defendant correctly – do you have the correct legal title for the defendant and does it match the information you provided to ACAS during the Early Arbitration?


The Intricacies of Filling Out the ET1 Form

Filling out the ET1 Form is a task that requires meticulous attention to detail. While the form itself is comprehensive, it's easy to overlook certain aspects that could be crucial for your case. For example, the section that allows you to elaborate on the events leading up to the claim is not just a narrative space. It's an opportunity to present your case in a compelling manner, highlighting key incidents and evidence that support your claim.


Common Mistakes to Avoid

When filling out the ET1 Form, there are several pitfalls you should steer clear of:

  • Vagueness: Being too vague about the nature of your claim can lead to misunderstandings later on.

  • Omissions: Leaving out key details or evidence can weaken your case.

  • Incorrect Information: Any discrepancies in the information provided can lead to delays or even dismissal of your claim.


Time Constraints and Deadlines

One of the most critical aspects of the ET1 Form is the timing. Typically, you have three months less one day from the date of the incident you're complaining about to submit the form. Missing this deadline could mean that you lose the opportunity to make your claim, regardless of its validity.


The Role of Legal Advice

While the ET1 Form is designed to be user-friendly, the complexities of employment law make it advisable to seek legal advice before submission. Legal experts can guide you through the nuances of your specific case, helping you fill out the form in a way that maximizes your chances of success.


After Submission: What to Expect

Once the ET1 Form is submitted and accepted, the Employment Tribunal will send a copy to your employer, who will then have 28 days to respond. This response is known as the ET3 Form. Failure of the employer to respond within this timeframe can result in a default judgment in favor of the employee.


The Tribunal Hearing

After the exchange of forms and preliminary procedures, a hearing date will be set. This is where both parties present their cases, and a panel of judges makes a decision based on the evidence and arguments provided.


Final Thoughts

The ET1 Form is more than just a bureaucratic requirement; it's the cornerstone of the Employment Tribunal process in the UK. From the moment you decide to fill it out to the final hearing, each step is crucial in determining the outcome of your employment dispute. Being informed, avoiding common mistakes, and understanding the timeline can make a significant difference in your pursuit of workplace justice.

How a Tax Accountant Can Help You with the ET1 Form?


How a Tax Accountant Can Help You with the ET1 Form?

When you think of an ET1 Form, the first professional that comes to mind is likely an employment lawyer, not a tax accountant. However, you'd be surprised to learn how a tax accountant can play a pivotal role in helping you navigate the complexities of the ET1 Form and the Employment Tribunal process. While they may not replace the expertise of an employment lawyer, their skills can complement legal advice in various ways.


Financial Documentation and Evidence

One of the most crucial aspects of any employment dispute is the financial documentation that supports your claim. Whether it's unfair dismissal, wage disputes, or discrimination, financial evidence often becomes the linchpin of your case. A tax accountant can help you gather, organize, and present this financial data in a manner that strengthens your claim. They can sift through payslips, tax returns, and other financial documents to pinpoint discrepancies or irregularities that may substantiate your case.


Calculating Losses and Claims

If you're claiming financial loss due to unfair dismissal or any other employment issue, calculating the exact amount can be complicated. A tax accountant can help you determine the financial impact, taking into account various factors like lost wages, benefits, and even potential future earnings. This precise calculation can be invaluable when filling out the ET1 Form and during the tribunal hearing.


Tax Implications of Settlements

If your case reaches a settlement, there are often tax implications that you need to consider. A lump sum payment may seem attractive, but without proper tax planning, you could end up losing a significant portion to taxes. A tax accountant can guide you through the tax implications of different types of settlements, helping you make an informed decision.


Expert Testimony

In some cases, the Employment Tribunal may require expert financial testimony to understand the nuances of your claim better. A tax accountant can serve as an expert witness, providing credible and professional insights into the financial aspects of your case. Their testimony can lend weight to your claim, especially when financial misconduct or complicated calculations are involved.


Streamlining the Process

The ET1 Form is a comprehensive document that requires meticulous attention to detail. A tax accountant can help streamline the process by ensuring that all financial data is accurate and well-organized. This not only saves you time but also minimizes the risk of errors that could delay or jeopardize your claim.


Financial Planning for the Future

Win or lose, an employment dispute can have long-term financial implications. A tax accountant can help you plan for various outcomes, advising you on how to manage your finances during and after the tribunal process. Whether it's budgeting for legal fees or planning for a potential loss of income, a tax accountant can provide practical financial strategies.



While a tax accountant may not be the first professional you think of when dealing with an ET1 Form, their expertise can be invaluable. From gathering financial evidence to calculating losses and understanding tax implications, a tax accountant can provide a multi-faceted approach to strengthen your employment tribunal claim. So, the next time you find yourself reaching for an ET1 Form, consider consulting a tax accountant alongside your employment lawyer for a well-rounded, robust strategy.
