What is HMRC Form IHT404?

Understanding the Basics of HMRC Form IHT404 in the UK

What is HMRC Form IHT404?

The HMRC Form IHT404, also known as the Account of Estate Information form, is a crucial document used in the United Kingdom for inheritance tax purposes. It is designed to establish the value of an individual's estate after their death. The form is used in conjunction with Form IHT400 and provides details of all UK assets that the deceased owned jointly with another person.

What is HMRC Form IHT404

Who Needs to Complete the Form?

If you are the executor of an estate, or if you are acting on behalf of the executor, then you will need to complete the IHT404 form. The executor is the person responsible for administering the estate of the deceased, which includes paying any outstanding debts and distributing the assets to the beneficiaries. In cases where there is no executor named in the deceased’s will, an administrator will be appointed by the court to carry out these duties. The administrator is also responsible for completing the IHT404 form.

What Information is Required?

The form requires detailed information about the assets and liabilities of the estate. Here are some of the key components:


  • Property: Includes any real estate owned by the deceased, such as houses or land.

  • Investments: Stocks, shares, bonds, and other financial investments.

  • Personal Possessions: Valuable items like artwork, antiques, and jewelry.

  • Bank Accounts: Savings accounts, checking accounts, and other financial accounts.

  • Other Assets: Cars, boats, and other personal property.


  • Debts: Outstanding debts like credit card debt, loans, and mortgages.

  • Funeral Expenses: Costs related to the funeral and burial of the deceased.

Additional Information

  • Beneficiaries: Names and addresses of those who will receive a portion of the estate.

  • Will: A copy of the deceased’s will, if available.

  • Probate: Information about the probate process, including the date probate was granted and the name of the probate court.

Deadlines and Penalties

The IHT404 form must be completed and submitted to HMRC within one year of the date of death. Failure to meet this deadline can result in penalties and interest charges. It's crucial to adhere to this timeline to avoid any legal complications.

How to Fill Out the Form

Filling out the IHT404 can be a complex and time-consuming process. The first step involves gathering all the necessary information about the assets and liabilities of the estate. This may require contacting various financial institutions to obtain statements and other documentation. Once all the information is gathered, you can proceed to complete the form, which is divided into several sections. Each section requires specific information about the estate, so it's important to read each one carefully and provide accurate details.

Navigating the Complexities of Inheritance Tax and Submission Process

Calculating the Inheritance Tax

Once you've filled out the IHT404 form with all the necessary details about the estate's assets and liabilities, the next step is to calculate the inheritance tax owed. This is a crucial aspect that requires meticulous attention, as several factors can affect the final amount. These factors include the total value of the estate and the relationship between the deceased and the beneficiaries.

Exemptions and Reliefs

It's important to note that certain exemptions and reliefs may apply, reducing the overall inheritance tax liability. For example, assets passed between spouses or civil partners are generally exempt from inheritance tax. Additionally, if the deceased left a certain percentage of their estate to charity, it could reduce the tax rate on some assets.

Tax Bands and Rates

In the UK, the standard inheritance tax rate is 40% on the portion of the estate above the £325,000 threshold. However, this rate may vary depending on specific circumstances, such as gifts given within seven years before death. Understanding these nuances can help you accurately calculate the tax owed.

Submitting the Form to HMRC

After calculating the inheritance tax, the next step is to submit the completed IHT404 form to HM Revenue and Customs (HMRC). This can be done either online or by mail. It's imperative to submit the form within one year of the date of death to avoid penalties and interest charges.

Payment Methods

The executor or administrator is responsible for paying the inheritance tax owed. This may require liquidating some assets or obtaining a loan to cover the tax liability. Therefore, it's crucial to plan ahead to ensure there are sufficient funds available for this purpose.

Additional Forms and Documents

Alongside the IHT404 form, you may also need to submit other forms and documents, such as the Grant of Probate or Letters of Administration. These legal documents give the executor or administrator the authority to manage the estate and distribute the assets to the beneficiaries.

Seeking Professional Advice

Given the complexities involved in calculating inheritance tax and submitting the IHT404 form, it's often advisable to seek professional advice. Tax advisors or estate planning experts can guide you through the process, ensuring that you meet all legal and tax requirements. They can also help you take advantage of any exemptions or reliefs that may apply, potentially saving you a significant amount of money.

The Relationship Between HMRC Form IHT404 and HMRC Form IHT400

The Relationship Between HMRC Form IHT404 and HMRC Form IHT400: A Comprehensive Guide

Introduction to HMRC Forms IHT404 and IHT400

When it comes to dealing with inheritance tax in the United Kingdom, two forms often come into play: HMRC Form IHT404 and HMRC Form IHT400. While both forms are integral to the inheritance tax process, they serve different purposes and require different sets of information. Understanding the relationship between these two forms is crucial for anyone responsible for administering an estate.

The Role of HMRC Form IHT400

Form IHT400, also known as the "Inheritance Tax Account," is the primary form used to report the value of an estate for inheritance tax purposes. This comprehensive form covers all aspects of an estate, including assets, liabilities, gifts, and reliefs. It is the form that provides HM Revenue and Customs (HMRC) with an overall picture of the estate's value and the inheritance tax due.

Key Components of IHT400

  • Assets: Information about all the assets owned solely by the deceased, such as real estate, bank accounts, and investments.

  • Liabilities: Details of any debts or financial obligations the deceased had at the time of death.

  • Gifts: Information about any gifts made by the deceased in the seven years prior to death.

  • Exemptions and Reliefs: Details of any applicable exemptions or reliefs, such as spousal or charitable exemptions.

The Role of HMRC Form IHT404

While Form IHT400 provides a broad overview of the estate, Form IHT404 focuses specifically on jointly-owned assets. This form is used to give a detailed account of assets that the deceased owned in partnership with another individual. It's an essential supplement to the IHT400 form, providing HMRC with a more nuanced understanding of the estate's value.

Key Components of IHT404

  • Jointly-Owned Property: Information about any real estate owned jointly by the deceased and another person.

  • Joint Bank Accounts: Details of any financial accounts held jointly.

  • Other Joint Assets: Information about other jointly-owned assets like investments or valuable items.

The Interplay Between IHT404 and IHT400

The relationship between these two forms is symbiotic. Form IHT400 may require additional forms like IHT404 to provide a complete picture of the estate. For example, if the deceased owned a home with a spouse, the details of this joint ownership would be reported on Form IHT404, while the overall value of the estate, including this jointly-owned home, would be reported on Form IHT400.

Importance of Accuracy and Consistency

It's crucial that the information provided on both forms is accurate and consistent. Any discrepancies between the two can raise red flags and may lead to delays in the probate process or even financial penalties.

Submission Process

Both forms should be submitted to HMRC, and it's advisable to submit them together to ensure that the inheritance tax calculation is accurate. The deadline for submission is typically within one year of the date of death.

Understanding the relationship between HMRC Form IHT404 and HMRC Form IHT400 is essential for accurate inheritance tax reporting. While the IHT400 form provides a comprehensive overview of the estate, the IHT404 form delves into the specifics of jointly-owned assets. Together, these forms offer HMRC a complete picture of the estate's value, ensuring that the correct amount of inheritance tax is calculated and paid. Therefore, if you're responsible for administering an estate, it's crucial to familiarize yourself with both forms and understand how they complement each other in the inheritance tax process.

Navigating the intricacies of HMRC Form IHT404 can be a daunting task, but with careful planning and attention to detail, it's possible to manage the process efficiently. By avoiding common pitfalls and following best practices, you can ensure that you fulfill your responsibilities as an executor or administrator, while also minimizing the inheritance tax liability.

The Pros and Cons of Hiring an Inheritance Tax Accountant for Inheritance Tax Forms

Inheritance tax (IHT) can be a complex subject for many, often requiring individuals to navigate multiple forms, legal jargon, and intricate financial calculations. If you find yourself in the position of dealing with an estate, you might wonder whether hiring an inheritance tax accountant is a good idea. This topic can be quite polarizing, as there are both strong advantages and some drawbacks to consider.

The Complexity of Inheritance Tax

One of the main reasons people consider hiring a professional is the inherent complexity of the inheritance tax system. Forms like IHT400, IHT405, and IHT404 are just a few examples of the paperwork required. Each form has its own set of rules, eligibility criteria, and documentation. A slight mistake in any of these can lead to delays or even financial penalties. An experienced accountant can guide you through this maze with expertise, ensuring that all the required forms are filled out correctly and submitted on time.

Financial Optimization

Another compelling reason to hire an inheritance tax accountant is the potential for financial optimization. Tax professionals often know the ins and outs of tax allowances, exemptions, and reliefs that you might not be aware of. For instance, they can advise you on how to best utilize the "gift allowance" or the "spouse exemption" to minimize the tax liability. Over the long term, the money saved through these legal avenues can far outweigh the accountant's fees, making it a wise investment.

Time-Saving and Stress Reduction

Dealing with the loss of a loved one is emotionally taxing. The added stress of handling complex tax forms can be overwhelming for many. An inheritance tax accountant can take this burden off your shoulders, allowing you to focus on other important aspects of life. Not to mention, the time you would spend deciphering tax laws and filling out forms could be used more productively elsewhere.

Accuracy and Legal Compliance

Tax laws are subject to change, and keeping up with the latest amendments is not everyone's cup of tea. An accountant stays updated with these changes as part of their profession. They ensure that your submissions are in full compliance with the current laws, reducing the risk of legal complications down the road.

Cost Factor

While there are numerous advantages, one cannot ignore the cost of hiring a professional. Accountant fees can range from a few hundred to thousands of dollars, depending on the complexity of the estate. For those who are handling a relatively straightforward estate, the cost may not justify the benefits.

DIY Resources

With the rise of online resources, software, and guides, some people find it easier than ever to take a DIY approach to inheritance tax. These tools can help you fill out forms and offer basic advice. However, they lack the personalized touch and expert advice that a qualified accountant can provide.

Final Thoughts

In conclusion, the decision to hire an inheritance tax accountant should be made based on your specific needs, the complexity of the estate, and your comfort level with financial and legal documents. If your estate involves multiple types of assets, various forms, and potential for legal complexities, the expertise of an accountant is invaluable. On the other hand, if you're dealing with a simple estate and are comfortable navigating tax laws, you might decide to handle it yourself. Regardless, carefully weigh the pros and cons to make an informed decision that suits your situation best.
