In this spotlight we dig into where this leaves the tax burden facing middle earners. International data shows that the rise in employer National Insurance contributions (NICs) last year and frozen tax thresholds in the UK have led to the largest annual rise in taxes on average workers across 33 comparable OECD rich countries. Strikingly, however, this was from a very low base – lower than the US, for example. The UK remains in the bottom third of such countries for the level of tax on an average worker, and the effective tax rate on a typical earner is still lower than it was before the financial crisis.
