HMRC Overpayment in Probate: How to Claim a Refund

Many families in England and Wales discover they have overpaid inheritance tax and can claim refunds from HMRC. This commonly happens when asset values change between the date of death valuation and the eventual sale. For instance, if a property was valued at £350,000 at the date of death but sold for £310,000 within the qualifying period, the estate may have overpaid IHT on the difference — and that overpayment is recoverable.

We will guide you through understanding and claiming these refunds, helping you navigate the process of reclaiming overpaid inheritance tax. Our aim is to provide clear, accessible guidance so that executors and personal representatives can protect the estate’s assets and ensure beneficiaries receive what they are rightfully owed.

According to recent data, thousands of estates pay inheritance tax each year — with the number rising as the nil rate band remains frozen at £325,000 (unchanged since 6 April 2009) — and many are eligible for refunds they never claim. You can find more information on this topic in an article on Saga.co.uk, which provides insights into the inheritance tax refund process.

Key Takeaways

• Overpayments commonly occur when properties or shares are sold for less than the probate valuation.
• Executors and personal representatives can claim refunds for overpaid inheritance tax.
• Specific statutory reliefs exist for property sold within 4 years and qualifying investments sold within 12 months of death.
• Strict time limits apply — you must sell within the qualifying period and submit your claim promptly.
• Processing a claim typically takes 6–8 weeks for straightforward cases, but complex claims can take 3–6 months or longer.

Understanding Probate Overpayment in the UK

Understanding probate and its associated tax implications is crucial for executors. When inheritance tax is calculated based on date-of-death valuations that later prove too high, the estate ends up overpaying HMRC — and executors have both the right and the duty to reclaim that money for the beneficiaries.

What is Probate?

Probate is the legal process by which a deceased person’s will is validated and an executor is formally authorised to administer the estate. Where there is no will, the process is called obtaining Letters of Administration, and the person appointed is known as an administrator. In either case, the personal representative must gather in all assets, settle debts and tax liabilities, and distribute the remaining estate according to the will or the rules of intestacy. The Grant of Probate (or Letters of Administration) is issued by the Probate Registry and gives the personal representative the legal authority to deal with the deceased’s assets. During this process — which typically takes between 3 and 12 months, and longer where property needs to be sold — all sole-name assets are frozen. Bank accounts cannot be accessed, property cannot be transferred, and beneficiaries must wait.

The Role of HMRC in Probate

HMRC plays a central role in the probate process. Before a Grant of Probate can be issued, the personal representative must report the estate’s value to HMRC — typically using form IHT400 for taxable estates — and pay any inheritance tax due or at least make arrangements to pay. IHT is charged at 40% on the taxable estate above the nil rate band (currently £325,000 per person, frozen since 6 April 2009 and confirmed frozen until at least April 2031). A reduced rate of 36% applies if 10% or more of the net estate is left to charity. Where the deceased’s spouse or civil partner died first without using their full nil rate band, the unused portion can be transferred — giving a married couple a combined nil rate band of up to £650,000. The Residence Nil Rate Band adds a further £175,000 per person (up to £350,000 for a couple) where a qualifying residential interest passes to direct descendants. HMRC collects the tax and may raise enquiries if they believe the valuations are inaccurate.

Common Causes of Overpayment

Overpayments to HMRC occur more frequently than many people realise. Executors face significant time pressure when calculating inheritance tax — the tax is due within six months of the end of the month of death, and the Grant cannot usually be obtained until the IHT position is settled. This often forces executors to use provisional or estimated valuations.

Key factors contributing to overpayment include:

• Property value declines: A property valued at £400,000 at the date of death that sells for £370,000 means IHT was overpaid on £30,000 — potentially £12,000 at 40%. With the average home in England now worth around £290,000, even modest market fluctuations can create significant overpayments
• Share portfolio losses: Quoted shares and unit trusts can fall significantly in value between the date of death and when they are sold
• Failure to claim available reliefs: Executors sometimes overlook reliefs such as Business Property Relief, the Residence Nil Rate Band (worth up to £175,000 per person), or the transferable nil rate band for surviving spouses
• Provisional valuations that are later found to be too high: Particularly common with chattels, unlisted business interests, and jointly-owned property

Understanding these factors can help executors take steps to minimise the risk of overpayment and, where overpayment has occurred, to reclaim what is owed to the estate.

Identifying Overpayment Situations

Executors must be vigilant in recognising potential overpayment situations throughout the probate process. Overpayments can arise from several distinct causes, and understanding each one is critical for effective estate administration.

Estate Valuation Errors

Estate valuation errors are the single most common cause of IHT overpayment. Executors may initially overvalue assets — particularly property, which accounts for the largest single asset in most estates. With the average home in England now worth around £290,000, even a modest overvaluation of 5–10% can mean thousands of pounds in excess IHT.

Two specific statutory reliefs address this. Loss on sale relief for property allows executors to substitute the actual sale price for the probate valuation if the property is sold within four years of death (though the claim must be made by the appropriate qualifying person). Loss on sale relief for qualifying investments (listed shares, unit trusts, and similar investments) allows the sale price to be substituted if sold within 12 months of death. Both reliefs can result in a recalculation of IHT and a refund of the overpayment.

To minimise valuation errors from the outset, executors should obtain professional valuations — especially for property, business interests, and valuable collections — rather than relying on rough estimates.

Tax Rate Miscalculations

Tax rate miscalculations can also result in significant overpayments. Common errors include:

• Failing to claim the transferable nil rate band: Where the first spouse or civil partner to die did not use their full £325,000 nil rate band, the unused portion transfers to the surviving spouse — potentially doubling the available allowance to £650,000. Many executors overlook this, effectively losing up to £325,000 of additional tax-free allowance
• Not claiming the Residence Nil Rate Band (RNRB): Worth up to £175,000 per person, the RNRB is available when a qualifying residential interest passes to direct descendants (children, grandchildren, or step-children). It is not available where the home passes to nephews, nieces, siblings, friends, or charities. For a married couple, this can mean up to £350,000 of additional relief — but it must be specifically claimed. The RNRB also tapers away by £1 for every £2 the estate exceeds £2,000,000 in value
• Missing the 36% reduced rate: Where 10% or more of the net estate is left to charity, the IHT rate drops from 40% to 36%. This is sometimes overlooked, particularly when charitable gifts form part of the residuary estate
• Not applying Business Property Relief or Agricultural Property Relief: These reliefs can reduce the taxable value of qualifying business or agricultural assets by up to 100%. However, from April 2026, the combined 100% relief is capped at the first £1 million of qualifying business and agricultural property, with 50% relief on the excess — a significant change for farming families and business owners

Unclaimed Assets

Unclaimed or overlooked assets can also contribute to overpayments — though perhaps not in the way you might expect. If debts, liabilities, or expenses that are deductible from the estate for IHT purposes are not properly accounted for, the taxable estate will be overstated. Similarly, if certain exemptions are not claimed — such as the spouse exemption for assets passing to a surviving spouse or civil partner — the estate may pay IHT unnecessarily.

Executors should conduct a thorough review of the estate to identify all deductible liabilities (including funeral expenses, outstanding debts, and professional fees) and ensure every available exemption and relief has been claimed.

For more information on claiming back overpaid inheritance tax, you can visit our guide on claiming back HMRC inheritance tax. This resource provides valuable tips for UK homeowners on probate reclaims and inheritance tax refunds.

HMRC’s own guidance confirms that executors should claim all available reliefs and exemptions, and that where IHT has been overpaid due to a subsequent fall in asset values, the appropriate relief should be claimed to obtain a refund. By being aware of these potential pitfalls, executors can take steps to ensure the estate does not pay more than it owes.

How to Check for Overpayments

To ensure the estate is not losing out on a legitimate refund, executors need to systematically check for inheritance tax overpayments. This involves a thorough review of the IHT account submitted to HMRC and a careful comparison of what was paid against what is actually owed.

Reviewing HMRC Tax Returns

The first step is to review the IHT400 (the inheritance tax account) and any supplementary pages submitted to HMRC. Examine every valuation figure and every relief or exemption claimed — or not claimed. Key things to verify include:

• Whether the estate valuations still reflect the amounts assets were actually sold for
• Whether all available reliefs were claimed — including the nil rate band, transferable nil rate band, Residence Nil Rate Band, Business Property Relief, and Agricultural Property Relief
• Whether the spouse exemption was correctly applied for assets passing to a surviving spouse or civil partner
• Whether all deductible debts, liabilities, and funeral expenses were included

Comparing Payments Made vs. Tax Due

Once you have reviewed the IHT account, the next step is to compare the total payments made to HMRC against the actual tax liability. This involves:

1. Reviewing all payment records — including any IHT paid directly from the estate’s bank accounts, payments made by instalments (common for property), and any tax funded by life insurance proceeds
2. Recalculating the total tax liability based on final asset values (including any assets sold at a loss) and all available reliefs and exemptions
3. Identifying any discrepancy between what was paid and what was actually due — this is the potential refund amount

Documentation Required

To support a refund claim, executors need to assemble comprehensive documentation. Having these records organised before you contact HMRC will significantly speed up the process:

By maintaining thorough and accurate records throughout the probate process, executors can efficiently identify any overpayments and proceed with claiming a refund from HMRC.

Eligibility Criteria for Refund Claims

To successfully claim a refund from HMRC for overpaid inheritance tax, executors must meet specific eligibility criteria. Understanding these requirements — and the time limits involved — is essential for recovering money that rightfully belongs to the estate.

Types of Estates Eligible

Any estate that has overpaid inheritance tax is potentially eligible for a refund. The most common situations include:

• Estates where property was sold at a loss: If land or buildings included in the estate are sold within four years of death for less than the probate valuation, the personal representative can claim loss on sale relief
• Estates where qualifying investments were sold at a loss: If listed shares, unit trusts, or similar qualifying investments are sold within 12 months of death for less than their date-of-death value, the lower value can be substituted
• Estates where reliefs or exemptions were not claimed: For example, if the transferable nil rate band, Residence Nil Rate Band, or spouse exemption was not applied in the original IHT account
• Estates with valuation errors: Where the original valuations are subsequently shown to have been too high — for instance, following a District Valuer’s revised assessment of a property

In all cases, the claim must be made by the executor or personal representative of the estate (or, in the case of loss on sale of property, the “appropriate person” who may include a beneficiary who inherited the property).

Time Limits for Claim Submission

Time limits vary depending on the type of relief being claimed, and missing these deadlines means losing the right to a refund:

• Loss on sale relief for property: The property must be sold within four years of death, and the claim submitted promptly after sale
• Loss on sale relief for qualifying investments: The investments must be sold within 12 months of death
• Overpayment due to error or unclaimed reliefs: Generally, claims must be made within four years from the end of the relevant period. However, it is always advisable to act as quickly as possible — HMRC is more receptive to claims made promptly

If you suspect IHT has been overpaid, do not delay. Investigate promptly and submit your claim within the relevant time limit.

Importance of Being Accurate

Accuracy is paramount when making a refund claim. Incorrect or incomplete information can lead to delays, additional HMRC enquiries, or even rejection of the claim. Executors should ensure that all documentation is thorough and accurate — including sale completion statements showing the actual sale prices achieved, updated valuations, and correctly completed claim forms. Where the claim involves complex calculations (for example, recalculating IHT after applying the Residence Nil Rate Band and the transferable nil rate band together), it is well worth seeking professional assistance to ensure the figures are correct.

Steps to Claim a Refund from HMRC

To successfully reclaim overpaid inheritance tax, executors need to follow a clear process. Each step matters, and getting the detail right from the start can save months of delay.

Preparing Your Documentation

The first step is to gather and prepare all necessary documentation. This includes:

• The original IHT400 and any corrective accounts (form C4) already submitted
• HMRC’s inheritance tax calculation and any correspondence confirming the tax paid
• Records of all IHT payments made — including bank transfer references and dates
• Completion statements for any properties or investments sold at a loss (showing the sale price and date)
• Updated professional valuations if the claim is based on a revised valuation rather than an actual sale
• Evidence supporting any additional reliefs or exemptions now being claimed

Create a checklist and work through it methodically. Missing even one document can result in HMRC asking for further information, which adds weeks to the process.

Submitting the Claim

Once your documentation is complete, you can submit the claim. The method depends on the type of overpayment:

1. Loss on sale relief for property: Submit the appropriate claim form to HMRC’s Inheritance Tax office, attaching evidence of the sale price and original probate valuation
2. Loss on sale relief for investments: Complete the relevant form listing all qualifying investments sold within 12 months of death, with evidence of sale prices
3. Corrective account (form C4): Where the original IHT400 contained errors or omitted reliefs, submit a corrective account with the revised figures and supporting evidence
4. General overpayment claim: Write to HMRC’s Inheritance Tax office, clearly setting out the basis of the claim, the amount overpaid, and enclosing all supporting documentation

Double-check every figure before submission. Include a covering letter clearly summarising what you are claiming, why, and the refund amount sought. Send everything by tracked post or use HMRC’s secure online channels where available.

Potential for Delays in Processing

HMRC processes refund claims carefully, but delays are common. Typical reasons include:

• Incomplete or inaccurate documentation — the single biggest cause of delay
• HMRC raising queries about the valuations or sale evidence provided
• High volumes of claims — particularly around the end of the tax year
• Complex estates involving multiple reliefs or cross-border elements

To minimise the risk of delays, ensure your claim is comprehensive and clearly presented from the outset. If you have not received an acknowledgement within four weeks, contact HMRC’s Inheritance Tax helpline to confirm receipt and ask for a reference number. Regular, polite follow-ups can help keep your claim moving through the system.

Common Challenges When Claiming Refunds

Claiming a refund from HMRC is not always straightforward. Executors often encounter challenges that require patience, persistence, and — in some cases — professional support to resolve.

Complicated Documentation Processes

HMRC requires detailed and accurate records to process a refund claim. For executors dealing with a complex estate — perhaps involving multiple properties, business interests, or overseas assets — assembling the necessary documentation can be time-consuming and stressful. Practical steps to manage this include:

• Start organising financial records as early as possible in the probate process — do not wait until you identify an overpayment
• Verify the accuracy of all documentation before submission, ideally with a second pair of eyes
• Be prepared to provide additional information if HMRC requests it — having well-organised files makes this much easier

HMRC Communication Issues

Communicating effectively with HMRC can sometimes be a challenge. Processing times vary, responses can be slow, and it is not always easy to reach the right department. To manage this:

• Keep a detailed log of all correspondence with HMRC — including dates, reference numbers, and the name of any HMRC officer you speak with
• Be clear and precise in all written communications — state the estate reference, the deceased’s details, and exactly what you are claiming
• Follow up in writing if a telephone conversation covers important points — this creates a paper trail
• If you are not getting a response, escalate by writing to HMRC’s complaints team or asking your solicitor to write on your behalf

Resolving Disputes

Disputes can arise if HMRC disagrees with a valuation, questions whether a relief applies, or calculates a different refund amount. Executors must be prepared to address these firmly but constructively.

By understanding these common challenges and preparing for them, executors can navigate the refund process more effectively. Staying organised, communicating clearly, and being proactive about resolving disputes are the keys to a successful outcome.

The Role of Solicitors in the Process

The probate process can be fraught with challenges, and solicitors play a vital role in guiding executors through the complexities of reclaiming overpaid inheritance tax from HMRC. As Mike Pugh often says, “The law — like medicine — is broad. You wouldn’t want your GP doing surgery.” The same applies here: inheritance tax refund claims benefit enormously from specialist expertise.

Why Consult a Probate Specialist?

Consulting a probate specialist can significantly simplify the process of claiming an IHT refund. These professionals have in-depth knowledge of the reliefs and exemptions available, the documentation HMRC requires, and the specific forms and procedures involved. They can spot opportunities for refunds that a lay executor might miss — such as the transferable nil rate band, the Residence Nil Rate Band (worth up to £175,000 per person), or loss on sale relief for properties or investments sold below probate value.

Perhaps most importantly, a specialist can review the original IHT account and identify whether reliefs were missed or miscalculated — potentially saving the estate tens of thousands of pounds.

How Solicitors Can Facilitate Claims

Solicitors and specialist estate practitioners can assist at every stage of the refund process. They can:

• Review the original IHT400 and identify any errors, omissions, or unclaimed reliefs
• Prepare and submit corrective accounts (form C4) or specific relief claim forms
• Liaise directly with HMRC on behalf of the personal representative — handling queries, providing additional evidence, and chasing progress
• Challenge HMRC’s valuation assessments where the estate disagrees with HMRC’s figures
• Handle disputes and, if necessary, lodge appeals through the formal tax tribunal process

By engaging a specialist from the outset — or even after probate has been granted — executors can improve their chances of a successful and timely refund.

Legal Costs to Consider

While solicitors provide invaluable assistance, executors should understand the costs involved. Probate solicitors typically charge either a fixed fee, an hourly rate, or — less commonly — a percentage of the estate value. For a straightforward IHT refund claim, the fees are often modest relative to the refund obtained. Ask for a clear fee estimate upfront, and compare this against the potential refund — in many cases, the professional fees are a fraction of the amount recovered.

It is also worth noting that the cost of not using a specialist can be far higher. Missed reliefs, incorrectly calculated claims, and delays caused by errors can cost the estate significantly more than the solicitor’s fee.

The Importance of Accurate Estate Valuation

Accurate estate valuation is the foundation of correct inheritance tax calculations. Get the valuation right, and the IHT figure follows naturally. Get it wrong — even by a relatively small margin — and the estate either overpays (losing money that should go to beneficiaries) or underpays (risking penalties and interest from HMRC).

Valuation Methods

Executors must value the estate as at the date of death. The standard required is “open market value” — the price the asset would fetch if sold on the open market at that date. Common valuation methods include:

• Property: Professional valuation by a RICS-qualified surveyor or experienced estate agent. For high-value or unusual properties, a formal surveyor’s report is strongly recommended. HMRC may refer the valuation to the District Valuer if they believe it is too low — or, relevantly for refund claims, executors can argue it was too high
• Quoted shares and investments: Valued using the “quarter-up” method — the lower quoted price plus one-quarter of the difference between the lower and higher prices on the date of death
• Bank accounts and savings: Balances at the date of death, plus any accrued interest
• Personal possessions and chattels: Estimated open market value. Professional valuations are advisable for jewellery, antiques, art, or collections
• Business interests: May require a specialist business valuation, particularly for unlisted companies or partnership interests

Impact of Misvaluations

Misvaluing an estate can have significant financial consequences. Consider a practical example: if the taxable estate (after the £325,000 nil rate band) is calculated at £275,000, the IHT bill comes to £110,000 at 40%. But if the property within that estate was overvalued by £50,000 — meaning the true taxable amount should have been £225,000 — the estate has overpaid by £20,000. That is £20,000 that should be in the beneficiaries’ pockets.

Seeking Professional Valuation Services

Given the stakes involved, obtaining professional valuations for significant assets is not a luxury — it is a sensible precaution. Professional valuers can help executors to:

• Ensure the estate is valued accurately at the date of death, reducing the risk of both overpayment and HMRC enquiries
• Provide robust evidence to support the valuation if HMRC raises questions
• Identify when a subsequent sale at a loss qualifies for loss on sale relief, enabling a refund claim

By investing in accurate estate valuation from the outset and reviewing those valuations against actual sale prices, executors can properly manage the estate’s IHT liability and reclaim any overpaid tax from HMRC.

Understanding HMRC’s Response Time

Understanding how long HMRC takes to process a refund is important for managing expectations — both your own and those of the beneficiaries waiting for their inheritance. The timeline depends on the complexity of the claim and HMRC’s current workload.

What to Expect After Submitting a Claim

After submitting a claim for an inheritance tax refund, the process typically involves several stages:

• Acknowledgement: HMRC should acknowledge receipt of your claim, usually within a few weeks. If you have not received an acknowledgement within four weeks, contact the Inheritance Tax helpline
• Review: HMRC will review your claim and the supporting documentation. For loss on sale relief claims, they will verify the sale prices against the original probate valuations
• Queries: HMRC may raise queries or request additional information. Responding promptly and fully to any queries will help avoid further delays
• Processing: Once satisfied, HMRC will process the refund. Payment is usually made by bank transfer or cheque to the personal representative

Average Timeframes for Refunds

The time taken to receive a refund varies considerably depending on the complexity of the claim:

These are general estimates. HMRC’s processing times can fluctuate, particularly during busy periods such as the months following the January self-assessment deadline.

Follow-Up Procedures

If you have not received a substantive response within the expected timeframe, follow up proactively:

• Contact HMRC’s Inheritance Tax helpline with your estate reference number and claim details
• If phoning, note the date, time, and name of the person you speak with
• Follow up in writing, summarising the telephone conversation and asking for a written response by a specific date
• If delays become unreasonable (typically more than three months beyond the expected processing time with no explanation), consider making a formal complaint through HMRC’s complaints process. HMRC may also be required to pay interest on late refunds

Keeping Records: Best Practices

Thorough record-keeping throughout the probate process is not just good practice — it is essential. If you later need to claim an IHT refund, the quality of your records will directly determine how quickly and smoothly that claim is processed. Good records also protect executors personally, as they have a legal duty to account for the estate’s administration.

Organising Financial Documents

Effective organisation of financial documents begins from the very start of the probate process. Key documents to organise include:

• The death certificate and Grant of Probate (or Letters of Administration)
• The original will and any codicils
• Bank statements, savings accounts, and investment portfolios as at the date of death
• Property valuations and any subsequent sale completion statements
• Details of all debts, liabilities, and funeral expenses
• Copies of the IHT400, supplementary pages, and any corrective accounts submitted
• Records of all IHT payments made, including bank references and dates

We recommend creating a structured filing system — whether physical folders or a well-organised digital system — with clear categories for each type of document.

Storing Important Correspondence

All correspondence related to the estate administration should be stored carefully and accessibly. This includes every letter and email from HMRC, the Probate Registry, solicitors, financial institutions, and beneficiaries. Best practice includes:

• Filing all correspondence in date order within each category
• Maintaining a log of all telephone calls with HMRC and other parties — noting the date, who you spoke with, and what was discussed
• Keeping both sent and received correspondence together so you can easily follow the thread of any conversation
• Retaining records for at least six years after the estate is fully administered — HMRC can raise enquiries for several years after probate is completed

Digital vs. Physical Record Keeping

Both digital and physical record-keeping have advantages, and a hybrid approach is often the most practical solution:

Whichever method you choose, the critical point is consistency. Adopt a system at the start of the probate process and maintain it throughout. If a refund claim becomes necessary months or even years later, well-organised records will make the difference between a smooth claim and a drawn-out process.

Changes to Inheritance Tax and Probate Regulations

Staying informed about changes to inheritance tax and probate regulations is essential for anyone administering an estate — and particularly for those considering whether an IHT refund claim may be possible. The landscape has shifted significantly in recent years, and further changes are on the horizon.

Recent Updates from HMRC

Several important changes affect estates and IHT refund claims:

• Nil Rate Band freeze extended: The IHT nil rate band has been frozen at £325,000 since 6 April 2009 — and is now confirmed frozen until at least April 2031. This means more estates than ever are being caught by IHT, as property values have risen significantly while the threshold has not moved. The average home in England is now worth around £290,000, meaning a homeowner with even modest savings and a pension is likely to have a taxable estate
• Residence Nil Rate Band freeze: Similarly, the RNRB has been frozen at £175,000 per person until at least April 2031
• Changes to Business Property Relief and Agricultural Property Relief (from April 2026): The combined 100% relief will be capped at the first £1 million of qualifying business and agricultural property, with 50% relief on the excess. This represents a significant change for farming families and business owners
• Inherited pensions to become liable for IHT (from April 2027): Pension pots that were previously outside the IHT estate will be brought within scope. This could substantially increase the taxable value of many estates and lead to more families facing IHT for the first time
• Excepted estates reporting changes: HMRC has simplified reporting for lower-value estates that do not need to pay IHT, but for taxable estates, the reporting requirements remain detailed

Implications for Future Claims

These regulatory changes have real implications for executors and beneficiaries dealing with IHT refund claims:

Staying Informed on Regulatory Changes

To stay ahead of these changes, executors and beneficiaries should:

• Regularly check HMRC’s guidance pages, which are updated when legislation or practice changes
• Consult with a solicitor or specialist estate planner when dealing with a taxable estate — particularly where the estate includes property, a business, or significant pension funds
• Consider proactive estate planning to reduce the IHT burden in the first place. As Mike Pugh says, “Plan, don’t panic.” Putting the right structures in place — such as a lifetime trust for inheritance tax planning — can reduce the estate’s exposure to IHT and minimise the risk of overpayment and the need for refund claims altogether. Trusts are not just for the rich — they’re for the smart

By understanding the current regulations and anticipating future changes, families can better protect their wealth and ensure they are not paying more inheritance tax than they need to.

Resources for Further Assistance

When dealing with overpaid inheritance tax during probate, having access to reliable resources makes a real difference. Navigating the refund process can be complex, and knowing where to turn for help is an important part of ensuring the estate receives the refund it is entitled to.

Official HMRC Guides

HMRC’s website provides detailed guidance on inheritance tax, including how to report the estate’s value, how to claim reliefs, and how to apply for a refund where IHT has been overpaid. Key resources include the IHT400 guidance notes, information on loss on sale relief for property and investments, and the corrective account (form C4) process. These are available free of charge on gov.uk and are regularly updated.

Support from Probate Solicitors

Engaging a solicitor who specialises in probate and inheritance tax can significantly simplify the refund process. They can review the original IHT account, identify unclaimed reliefs, prepare the refund claim, and liaise with HMRC on your behalf. If you are unsure whether the estate has overpaid, a specialist review is often the fastest way to find out — and the potential refund typically far exceeds the professional fee involved.

Charitable Organisations and Advice Services

Several charitable organisations offer free guidance on probate and inheritance tax matters. Citizens Advice can help with general queries about the probate process. The Money and Pensions Service (MoneyHelper) provides free, impartial guidance on financial aspects of bereavement, including IHT. STEP (the Society of Trust and Estate Practitioners) maintains a directory of qualified trust and estate professionals. These resources can provide valuable support, particularly for executors who are managing the process without a solicitor.
