Unexpected inheritance tax demands have struck more than 14,000 households following unsuccessful attempts to reduce their estates through lifetime gifts.
The wealthiest families have encountered tax bills of over £3million after a benefactor has passed away before the crucial seven-year period has finished.
These substantial charges arise when people give away valuable assets or funds but do not live long enough for the gifts to fall outside inheritance tax rules.
Data obtained through freedom of information requests to HM Revenue & Customs showed that 14,030 gifts became subject to inheritance tax during the 2022-23 financial year.
The costliest 25 unsuccessful transfers averaged £7.9million each after reliefs and allowances. When the person died within three years of making such large gifts, the tax bills reached £3.1million per family.
The inheritance tax system charges 40 per cent on estates above the £325,000 nil-rate band.
This threshold increases to £500,000 when the deceased's main home is passed to children or grandchildren, provided the total estate remains under £2million.
Transferring wealth before death represents a common strategy for reducing inheritance tax exposure. However, the donor must remain alive for a full seven years following the transfer for it to fall completely outside their taxable estate.
Britons are looking for ways to avoid paying inheritance tax | GETTY Deaths occurring between three and seven years after gifting trigger reduced tax rates ranging from eight to 32 per cent.
This sliding scale only takes effect when total gifts within the seven-year period exceed the £325,000 nil-rate band.
Transfers made less than three years before death incur the standard 40 per cent rate.
Michelle Holgate from investment firm RBC Brewin Dolphin, which obtained the data, noted that "strategic gifting was once seen as a tactic of the super-affluent, but has now gone mainstream."

Inheritance tax can be reduced by giving gifts - but rules do apply | GETTYShe highlighted particular interest from agricultural communities: "We're getting inquiries in particular from farmers looking to pass on assets such as land to the next generation without triggering a big inheritance tax bill."
The typical unsuccessful gift amounted to £171,000 after reliefs and exemptions, generating a tax liability of £68,400 when death occurred within three years.
Ms Holgate emphasised families' determination to preserve their legacies: "People are naturally protective of family businesses, which in some cases have been built up over several generations.
They want to keep these businesses in the family and see them thrive long into the future."

From April 2027, private pension funds will become subject to inheritance tax for the first time, removing a previously protected asset class from estate planning strategies.
Agricultural and business property reliefs face substantial restrictions from April 2026. These allowances, which previously enabled tax-free transfers of farms and family enterprises, will be capped at £1million for combined holdings.
Assets exceeding this threshold will receive only 50 per cent relief, creating an effective 20 per cent tax rate on the excess.
The Office for Budget Responsibility projects inheritance tax receipts will nearly double within five years, reaching £14.3 billion as these measures take effect.
