Following the vote of no confidence in the prime minister on 6 June 2022, calls have been made for the government to introduce a change in economic and fiscal policy. In a cabinet meeting the day after the vote, the prime minister was reported as saying: "We will have the scope, by delivering tax cuts, I think, to deliver considerable growth in employment and economic progress."
Two thirds of Britons say the government is currently handling the economy poorly and this view has been worsening since May 2021. The UK’s growth is forecast by the OECD to be the worst in the G7 in 2023. They have also made calls for the government to cut taxes before growth stalls.
The March 2022 spring statement lays out the urgency of the economic crisis enveloping the country. Growth forecasts have shifted downwards and inflation is set to reach almost 9 per cent by the end of 2022. By 2026-27, national account taxes are forecast to be their highest since the late 1940s.
Using a dynamic tax model that has been commissioned by the TaxPayers’ Alliance, this note demonstrates the real-world impacts on a range of potential tax cuts. The results include the change to real wages, investment spending and GDP.
- The national insurance rises in April 2022 continue to drag on the beneficial impacts of other potential tax cuts.
- Cutting the basic rate of income tax by either one or two pence would still mean lower average weekly earnings by 2029 because of the national insurance rises in April 2022.
- A reduction in the main rate of VAT to the 2010 level of 17.5 per cent could mean GDP being £30 billion higher by 2029. However, if the national insurance rises from April 2022 are not reversed, it would only be £3 billion.
- Combining a cut in VAT, income tax and raising the national insurance threshold could mean GDP being £56 billion higher, average weekly earnings £13 higher and investment spending up £12 billion by 2029.
