Everyone over 40 would start contributing towards the cost of care in later life under radical plans being studied by ministers to finally end the crisis in social care. Under the plan, over-40s would have to pay more in tax or national insurance or be compelled to insure themselves against hefty bills for care when they are older. The money raised would then be used to pay for the help that frail elderly people need with washing, dressing and other activities if still at home, or to cover their stay in a care home. The plans are being examined by Boris Johnson’s new health and social care taskforce and the Department of Health and Social Care (DHSC). They are gaining support as the government’s answer to the politically perilous question of who should pay for social care. Sources say the principle of over-40s meeting the cost of a reformed system of care for the ageing population is emerging as the government’s preferred option for fulfilling the prime minister’s pledge just over a year ago to “fix the crisis in social care once and for all”. Social care is a devolved matter but the plans could apply to the whole of the UK as they may involve the tax system. Matt Hancock, the health and social care secretary, is a keen advocate of the plan. He has been championing it in discussions that have resumed recently about the government’s proposals to overhaul social care. Officials say there is a “renewed urgency” in Downing Street and the DHSC to come up with a solution. The system that officials are considering is a modified version of how Japan and Germany fund social care. Both are widely admired for having created a sustainable way of financing social care to deal with the rising needs an ageing population brings. In Japan everyone starts contributing once they reach 40. In Germany everyone pays something towards that cost from the time they start working, and pensioners contribute too. Currently 1.5% of every person’s salary, and a further 1.5% from employers or pension funds, are ringfenced to pay for care in later life. Adopting a similar approach would let Johnson say he has ended the situation whereby some pensioners deemed too wealthy to qualify for local council-funded care have to sell their homes to pay care home costs, which can exceed £1,400 a week.
