Britons using the annual inheritance tax gifting allowance are now able to pass on far less wealth in real terms than families could more than four decades ago. The £3,000 exemption, unchanged since 1981, has been heavily eroded by inflation, according to legal experts.
TWM Solicitors, a private wealth and family law firm, warned that the frozen threshold has effectively become a “stealth tax” as inflation and rising asset prices continue to reduce the allowance’s value year after year. The issue has drawn attention to the wider effect of fiscal drag across the UK tax system. According to TWM Solicitors, cumulative inflation has risen by 354% since the gifting allowance was introduced, while the threshold itself has remained fixed at £3,000.
Had the allowance increased in line with inflation, it would now stand at roughly £13,600. Instead, families are still limited to the same nominal figure set more than 40 years ago when passing on tax-free gifts during their lifetime.
Frozen Threshold Reduces Real Value of Tax-Free Gifts
The annual inheritance tax gifting exemption allows individuals to transfer up to £3,000 each year without the gift being counted toward their estate for inheritance tax purposes. Gifts exceeding this amount may still become exempt if the donor survives for seven years after making them.
According to TWM Solicitors, the purchasing power of the allowance has fallen sharply since the early 1980s. In 1981, £3,000 represented around 16% of the average UK house price. Today, the same figure equates to about 1%.
The firm also noted that the allowance once covered approximately five months of wages for the average British man and nearly eight months of earnings for the average British woman. In current terms, it amounts to roughly one month’s salary. Duncan Mitchell-Innes of TWM Solicitors said the allowance was originally designed to help families pass on “meaningful gifts” without creating a future inheritance tax burden.
“In 1981, families could gift enough for a house deposit or even a brand-new Mini tax free,” he said. “Today, the same allowance barely covers the cost of replacing an average boiler.” According to the legal firm, there is currently no indication that the Government plans to raise the threshold in line with inflation.
Families Face Growing Administrative Burden
The shrinking real-world value of the allowance has also increased the administrative pressure on families dealing with inheritance tax matters after a death.
Under current rules, executors may need to trace gifts made in the seven years before someone dies when completing inheritance tax returns. TWM Solicitors warned that smaller and more routine financial support payments are now being captured by a threshold that has not evolved with living costs.
Mitchell-Innes said a £3,000 gift today “could be as ordinary as a few months’ rent,” making it easier for families to overlook transactions while managing estates and property valuations. According to the solicitor, this raises the risk of compliance issues and possible HMRC penalties if gifts are missed during the reporting process.
The annual exemption is separate from other inheritance tax rules that allow “gifts out of surplus income,” as well as the broader seven-year exemption for larger lifetime transfers.
TWM Solicitors argued that the continued freeze effectively increases inheritance tax exposure over time without formally changing tax rates. The firm described the process as fiscal drag, where static tax thresholds gradually pull more people into taxation as prices, wages and property values rise.
