The government claims that the UK income tax has only three tax bands: 20%, 40%, and 45%. This assertion is straightforward but disingenuous. Once income exceeds £100,000, the personal allowance begins to taper off, resulting in a loss of £1 of the allowance for every additional £2 earned. Consequently, for every additional £100 earned, one must pay an extra £40 in standard tax, plus £20 due to the diminishing personal allowance. The effective tax rate thus reaches 60%, which is not only high but punitive.
While the government verbally advocates for rewarding hard work, the system effectively penalizes it. Individuals earning between £100,000 and £125,140 face a marginal tax rate that is higher than that of those with greater incomes. Taxpayers mistakenly believe they remain within the 40% band, unaware that they have inadvertently entered a higher tier. The tax system officially lists three bands, but in reality, there are four. This is not a technical error but a political obfuscation—hiding a very high tax rate within the fine print, while it does not appear in the charts.
Adding to this is a 2% employee National Insurance contribution, bringing the actual marginal tax rate to 62%. For every £100 increase in salary, employers must also pay 15% in employer insurance, resulting in a total cost of £115, with the employee receiving only £38. Two-thirds of the earnings are absorbed by the treasury. Such a system punishes overtime, promotions, and any additional effort.
The victims are not the wealthy but the professional middle class—consultant doctors, corporate managers, and university professors. They are not a privileged class but have become scapegoats of the tax system. Some individuals deliberately remain at £99,000, avoiding promotions or extra work to escape the system’s ‘penalty for effort.’ This phenomenon is evident in the healthcare, education, and research sectors. While the UK claims to want to boost productivity, it undermines incentives through its policies.
The essence of economics lies in incentives. When the rewards for hard work are penalized, individuals naturally choose to withdraw. One of the root causes of the collapse of communist regimes was the realization that working harder yielded no benefits while doing less incurred no penalties. Today’s 60% tax band in the UK, though not a communist policy, repeats the same error: severing the link between effort and reward.
To reform the system, the tapering of the personal allowance should be abolished, and three clear tax bands should be re-established: 20%, 40%, and 50%, with the 50% rate applying from £100,000 onwards. Based on existing data, considering that a decrease in marginal tax rates would encourage more people to work harder, the revenue would not differ significantly from current levels. An honest tax system should be comprehensible and encourage compliance. What the UK needs is not hidden traps in the fine print but a framework that rewards effort and restores trust.
