A think tank has proposed giving all 25-year-olds born in Britain a “citizen’s inheritance” of £10,000 that could be spent on rent or a home purchase.

The suggestion, from the Resolution Foundation, forms part of a number of measures to address “inter-generational unfairness”.

The Resolution Foundation’s Intergenerational Commission – set up to look at issues affecting younger generations such as saving for their retirement and getting on the property ladder – suggests that from 2030, citizen’s inheritances of £10,000 should be available from the age of 25 to all British nationals or people born in Britain as restricted-use cash grants.

They would have to be spent on funding education and training, deposits for rental or home purchase, investment in pensions or start-up costs for new businesses that are also being supported through recognised entrepreneurship schemes.

To fund this, the commission proposes abolishing inheritance tax and replacing it with a lifetime receipts tax with lower rates and fewer exemptions.

Everyone would have a lifetime receipts tax allowance of £125,000 rising with inflation. Beyond this threshold, any new gifts or inheritances received would be taxed – at significantly lower rates than the current system. Lifetime receipts above the allowance and up to £500,000 should be taxed at a basic rate of 20%, with receipts above £500,000 being taxed at 30%.

This compares with the current system that starts at charging 40% on inheritances from individual estates worth above a £325,000 threshold.

Other proposals to support the younger generation include halving Stamp Duty on property purchases by first-time buyers and movers and retaining a higher tax rate on the purchase of additional properties.

It also proposes introducing a time-limited cut to Capital Gains Tax for owners of additional properties selling to first-time buyers, requiring landlords in all parts of the UK to be licensed, and replacing council tax with a progressive property tax for home owners.
