A simple single rate

Calls for a simplified tax and benefit system have been ongoing and many see the Coalition’s plans for a Universal Credit as a step in the right direction. However, a second suggestion set out in a report by lobbying groups is to introduce a single rate of income tax at 30%. The argument is that it will simplify the system, help lower income earners and boost growth.

As well as the introduction of a single rate of income tax, The 2020 Tax Commission’s Report also suggests an increase in the personal allowance to £10,000; scrapping National Insurance Contributions, stamp duty, inheritance tax and air passenger duty, as well as cutting fuel duty by 5p. For the typical tax payer, it may sound great – the difference between your gross and your net pay would narrow, but the wider consequences must be considered. Although a single rate of income tax would undoubtedly simplify the system, the impact on government finances must be considered. The commission predicts that overall borrowing would fall by £35bn after 15 years, but that the national deficit would increase by £49.1bn in the first year. Perhaps not an ideal solution given the current state of the national deficit!

The report does contain some radical change, but the idea of simplification is well-recognised as a necessary principle of any tax system. As the Chairman of the Commission, Allister Heath said:

It is time for Britain to make a vital choice between tweaking the status quo and letting our economy continue to be crippled by complex and punitive taxes, and drastically changing course with a radical but realistic plan for a tax system fit for the 21st century.

The 2020 Tax Commission has set out that plan and would ensure that income is taxed once at a single, much more reasonable rate. It could create the conditions to establish the UK as a global trading hub, generating renewed prosperity for all those who live and work here.

The current system is complex and many people end up paying an extremely high rate of tax, once everything has been paid. The Guardian article below gives a nice illustration. “If you earn income from shares, first corporation tax is taken out of the profits. Then you pay taxes on the dividends. Then because those profits drive up the share price you pay capital gains tax as well.” With a simpler and fairer tax system, the Commission argues that it will boost the competitiveness of the UK economy and help boost its struggling growth rate. How many, if any, of these proposals will be incorporated into the government’s plans is anybody’s guess, but it definitely presents an interesting solution and problem.
