The hon. and learned Lady tempts me to talk about a subject from a previous portfolio that is very close to my heart, but it is clearly a matter on which, for the most part, the Department of Health leads. We are committed to tackling this right across the Government. To take one aspect—she mentioned products that are not within the scope of the levy—Public Health England, working very closely with manufacturers, is leading a very ambitious programme of work, which is well under way, to set ambitious targets. When we look at the progress this country has made in our world-leading salt reduction programme, we can see that it was all done through such close working, as well as by being ambitious and by pushing the industry. Alongside the levy, which has turbo-charged that work, that is a very substantial element of the plans. The Department of Health is doing other things, in particular working with schools, and with the money from the levy more can be done.
Let me turn to another theme of the Finance Bill, which we have talked about as a strategic challenge not just for this country but for many developed countries: the different ways in which people are now working. The Bill takes important steps within the tax system to adjust to and reflect the changing ways in which people are choosing to work. For example, individuals who work through a company currently pay significantly less tax than individuals who are self-employed or work as employees. This is true even in many cases where individuals are doing very similar work. Indeed, the Office for Budget Responsibility estimates that the faster growth of new incorporations compared with the growth of employment would reduce tax receipts by an additional £3.5 billion in 2021-22. The Government are committed to helping all businesses, large and small, in all parts of the UK to succeed, but we are clear that the tax system must ensure fair treatment between individuals working in different ways, and of course it must be sustainable.
The Bill will take some initial steps to help to address this issue and deliver a tax system that is fair and works for everyone. First, the off-payroll working rules will be amended for public sector engagements, with responsibility for administering the relevant tax rules moving to the body for whom the individual is working. This change will help to tackle widespread non-compliance with the current rules, which costs more than £700 million each year across the economy. Secondly, from April 2018 the Bill will reduce the dividend allowance from £5,000 to £2,000. This change will help to reduce the tax differential between individuals working for their own company and those working as employees or self-employed. Crucially, it will raise much needed revenue to invest in our public services, including adult social care, as the Chancellor explained at the Budget.
I want to assure right hon. and hon. Members that there will still be a healthy environment for investors. The allowances that the Government have introduced or raised mean that a general investor will still be able to invest about £50,000 without paying any tax on the resulting dividend income. For example, we have increased the amount that individuals can save or invest tax-free through an ISA by the largest ever amount: up to £20,000 this tax year. This and other allowances mean that 80% of all general investors will still pay no dividend tax on their investments. As I have set out, this change
will help to address the rising cost to the public finances of the growth in incorporation. It is in that context that the change to the dividend allowance should be considered.
The Bill will further modernise the tax system by legislating for making tax digital. Just as taxation must adjust to the world around it, so must the administration of the tax system. With millions of businesses already banking, paying bills and buying services online, making tax digital is a natural extension of this reality. The Government have brought large swathes of government services into the digital age, including within the tax system, and we need to go on to complete that journey. Businesses will feel the benefit too, being helped to get their tax right first time and cutting down on excessive administrative burdens over the long term. Simultaneously, making tax digital will help to tackle the tax gap, as error alone cost the Exchequer £8.7 billion in 2014-15.
