The Importance of Record-Keeping for Tax Compliance
When it comes to tax, attention to detail is crucial. The difference between successfully claiming tax reliefs and allowances or facing a challenge from HM Revenue and Customs (HMRC) often comes down to having the right documentation. Whether dealing with inheritance tax (IHT), discretionary trusts, or business transactions, maintaining clear records can be the deciding factor in a tax dispute.
1. Documenting Gifts for Inheritance Tax Relief
One of the most overlooked tax reliefs is the IHT exemption for ‘normal expenditure out of income’. This exemption can help individuals pass on wealth without using their IHT nil-rate band or triggering a tax liability.
To qualify, the gift must:
✔ Be part of the donor’s normal expenditure.
✔ Be made out of income, taking one year with another.
✔ Leave the donor with sufficient income to maintain their usual standard of living.
Proving a Gift is ‘Normal’
The challenge with this relief is proving that gifts are part of normal expenditure rather than ad hoc transfers of wealth. HMRC provides no definitive list of acceptable evidence, but strong documentation increases the likelihood of a successful claim.
Recommended documentation includes:
- A letter or deed of intent from the donor explaining the circumstances and intention of making gifts.
- A bank standing order that demonstrates regularity (e.g., a recurring transfer to the recipient).
- A letter or email to the recipient, confirming the gift and its purpose.
Without sufficient evidence, HMRC could challenge the relief and subject the gift to IHT at 40% if the donor dies within seven years.
2. Using a Letter of Wishes for Discretionary Trusts
Many people set up discretionary trusts in their wills, intending to provide financial security for family members while retaining flexibility over how funds are distributed.
Under such arrangements, trustees have full discretion over how assets are distributed among beneficiaries. However, some individuals prefer a specific beneficiary—such as a surviving spouse or child—to be the principal recipient.
Can You Guide the Trustees?
While a will cannot bind trustees, testators can provide a letter of wishes to express their preferred approach. This letter is not legally binding but serves as guidance for the trustees when exercising their discretion.
Key Considerations for a Letter of Wishes
It must not impose obligations on the trustees.
It must not conflict with the terms of the trust.
It should be clear and practical, detailing the testator’s preferences.
Having a well-drafted letter of wishes ensures that trustees are aware of the testator’s intentions without compromising the flexibility of the trust.
3. Separating Business Transactions from Personal Gifts
It is common for self-employed individuals to provide goods or services to family members. However, HMRC carefully scrutinises payments between relatives to determine whether they represent:
- Genuine business transactions (taxable income).
- Personal gifts (not taxable).
HMRC’s Stance on Gifts Between Relatives
HMRC’s Business Income Manual (BIM41810) states:
“Where a trader receives what is termed a gift from a close relative (that is forebears, offspring, brothers and sisters), it may normally be accepted that the sum comes to the trader not in that capacity but by virtue of the close personal relationship.”
How to Ensure Payments are Correctly Categorised
✔ If a payment is a genuine business transaction: Issue a formal invoice and record it in business accounts.
✔ If a payment is a gift: Ensure it coincides with a significant event (e.g., birthdays or Christmas) and is accompanied by a greeting card or email confirming the intention.
Warning: Do not attempt to disguise payments for goods or services as voluntary gifts—this could lead to tax penalties if discovered by HMRC.
4. The Role of Evidence in Tax Disputes
If HMRC challenges a taxpayer’s claim and the dispute reaches the First-tier Tax Tribunal, the outcome depends on documentary evidence and the balance of probabilities.
✔ Good record-keeping improves the chances of success in a tax dispute.
✔ Verbal explanations hold little weight without supporting documentation.
✔ HMRC tends to favour consistent, well-documented financial records.
Practical Tips for Protecting Tax Reliefs
- Keep detailed records of financial transactions, including bank statements, emails, and letters.
- Document gifts properly to ensure IHT exemptions apply.
- Use letters of wishes for discretionary trusts to guide trustees without restricting their powers.
- Clearly differentiate between personal gifts and business payments to avoid unnecessary tax liabilities.
- Review tax planning strategies regularly to align with changes in HMRC guidance and tax law.
