HMRC primarily learns about gifts from parents through mandated reporting by executors when managing an estate, specifically for gifts made within seven years of death. Executors must file form IHT400 and disclose gifts, which are tracked via bank records and, if needed, cross-referenced with bank interest data.
If you filled out a gift aid from with the charity then HMRC will get that information from the charity, but it's not likely that it automatically gets linked to you. They only need to submit your name, post code, and house number and it's on you to inform the charity when you move if it's a recurring donation.
Of course, you can also give more than the annual $18,000/$36,000 exclusions, but if you give more than that amount, you typically have to file the gift tax return Form 709 so the IRS can track those gifts and apply them to your lifetime estate and gift tax exemption.
You do not pay tax on a cash gift, but you may have to pay tax on any income that the cash gift generates. For example, if you place the cash gift in a bank or building society account, you may have to pay tax on the interest you earn on that account.
At a glance:
You don't have to report gifts to the IRS unless the amount exceeds $19,000 in 2025. Any gifts exceeding $19,000 in a year must be reported and contribute to your lifetime exclusion amount. You can gift up to $13.99 million over your lifetime without paying a gift tax on it (as of 2025).
As the recipient, you do not pay tax on a gift of £50,000. For the giver, this would be a Potentially Exempt Transfer. As long as they live for seven years after giving it, it will be entirely free of Inheritance Tax.
While there are strict rules around the amount you can gift each year, undeclared or wrongly declared gifts may trigger HMRC scrutiny.
Banks in the UK do not automatically notify HMRC of large deposits; however, they are legally required to report suspicious transactions to the National Crime Agency (NCA) through Suspicious Activity Reports (SARs), which may indirectly reach HMRC if tax evasion is suspected.
But the IRS also can search for unreported gifts during your lifetime. For example, it searches public property records in some states, such as real estate title records. Transfers that appear to be between relatives or that were made without compensation can be compared to filed gift tax returns.
Can I give my son or daughter £20,000? While you can give your son or daughter a cash gift of £20,000 (or more), there may be tax implications. That's because any money you give that exceeds your £3,000 tax-free gift allowance will be added to the value of your estate and may be subject to inheritance tax when you die.
Yes, you can likely give your daughter $50,000 tax-free by using your annual gift exclusion and lifetime exemption, but you'll need to file Form 709 with the IRS to report the gift exceeding the annual limit ($19,000 in 2024/2025). The $50,000 gift reduces your large lifetime exemption (over $13 million in 2024/2025), meaning you won't pay tax on it unless your total lifetime gifts exceed that huge amount; your daughter never pays gift tax on the money.
HMRC can impose financial penalties when gifts are not declared correctly and the Executors may be liable to pay these penalties themselves. However, it is not always the Executors who are responsible for the payment of the penalties.
Nevertheless, gifts that exceed the annual exclusion amount (taxable gifts) are required to be documented with the filing of a Gift Tax Return (Form 709). This is the IRS' way of tracking the amount of your taxable gifts during your lifetime and the balance of your Exemption Equivalent remaining at death.

As of 2025, you can give an adult child up to $19,000 in a year before you must file a gift tax return. If your adult child is married, you can also give up to $19,000 to their spouse.
The IRS primarily learns about large gifts when you file Form 709, the Gift Tax Return, for amounts exceeding the annual exclusion (e.g., $19,000 per person in 2025). They can also discover gifts through third-party reporting (banks reporting large cash transfers), audits of your estate, or by matching transactions to public records, especially for significant asset transfers like property, which might trigger property tax reassessments.
There's no limit on how much money you can give or receive as a gift! However, there are some occasions where tax may be payable, or capital gains tax (CGT) may apply. For example, in some instances when gifting property, shares or crypto assets, or when receiving money or an asset from a non-resident trust.
The most common trigger for an investigation is submitting incorrect figures on a tax return - so it's worth asking an accountant to offer professional advice about your accounts and check over your tax returns before you send them.
What Can Trigger a Gift or Estate Tax Audit? Here are some of the common factors that can lead to gift or estate tax audits: Total estate and gift value: Generally speaking, gift and estate tax returns are more likely to be audited when there are taxes owed and the size of the transaction or estate is relatively large.
HMRC gets a tip-off
The most common reasons are: Unhappy or jealous acquaintances who may suspect dubious activity. The existence of a cash-only policy at your business. Living a lifestyle beyond your apparent means.
There are several ways to transfer property to a child tax-free, including leaving it in a will, gifting it using lifetime and annual exclusions, selling it, or placing it in an irrevocable trust.
You can gift up to £3,000 every tax year free of Inheritance Tax (IHT). This is your gifting allowance, and you can gift it all to one person or split it between several. You can roll the gifting allowance over for one year too. This is subject to other taxes, depending on how the gift is made.
Certain gifts don't count towards this annual exemption. As such, no Inheritance Tax is due on them. Gifts worth more than the £3,000 allowance in any tax year might be subject to Inheritance Tax.
