When a loved one passes away, their financial affairs do not simply come to an end. Among the many responsibilities faced by personal representatives - whether executors named in a will or administrators appointed by the court - is the duty to manage the deceased’s UK tax affairs.
Navigating the UK’s income tax rules in the context of a deceased estate can be complex, especially at a time when families and executors are already coping with the emotional challenges of loss.
From understanding when to notify HMRC to completing final tax returns and calculating estate income during the administration period, there are important legal and procedural steps to follow. This article sets out clear and practical guidance to support that process.
To help simplify the process, the UK government offers a ‘Tell Us Once’ service.
As the name suggests, you only need to notify the government once. This service informs multiple departments - including HMRC, the DVLA, Passport Office, and Department for Work and Pensions - of the individual's death, saving time and reducing administrative burden.
Check if the deceased was registered for Self Assessment.
HMRC will usually use PAYE records to determine whether any action is needed. They may contact the personal representative (PR) directly with further instructions.
The administration period runs from the date of death until the estate has been fully distributed (or, at least, until all income-generating assets have been sold or transferred).
This depends on whether the estate is classed as simple or complex.
You can report income and any tax due through an informal arrangement, typically by writing to HMRC with a breakdown of income and tax payable.
If the estate is complex:
You must register the estate for Self Assessment, obtain a Unique Taxpayer Reference (UTR), and file formal tax returns for each tax year of the administration period.
In both simple and complex estates, if the tax liability is very small, it may fall within HMRC’s de minimis thresholds. This means HMRC may choose not to require payment or formal reporting.
This is determined on a case-by-case basis. Even if the liability is low (often under £100), it’s important to disclose income and gains informally and await HMRC’s response. Keep full records in case further information is requested.
Once the estate has been administered - with all assets sold or transferred and liabilities settled - personal representatives should prepare final estate accounts. These summarise all income received, expenses paid, and amounts distributed to beneficiaries.
If income was received during the administration period (such as bank interest, dividends, or rental income), tax may be due. After confirming that all liabilities have been met, the estate can be distributed.
Where income has already been taxed, you may need to issue R185 (Estate Income) forms to beneficiaries. These allow them to report any income received on their personal tax returns, if required.
Managing income tax for a deceased estate is a critical responsibility for personal representatives. While HMRC provides tools and some flexibility - particularly for simple estates - the process still involves legal, financial, and administrative obligations that must be handled with care and accuracy.
By following the steps outlined above, maintaining good records, and seeking guidance where needed, you can help ensure the estate’s tax affairs are managed correctly and efficiently, allowing for a smooth and timely distribution to beneficiaries.
