The Stealth Taxes: How the UK System Kills Your Compounding

The UK tax system has hidden traps that can drastically reduce the effective income of high earners, especially those earning over £100,000.

Between £100,000 and £125,140, the combination of the tapered Personal Allowance and the 40% Higher Rate tax results in an effective marginal rate of 60%.

Families earning over £60,000 can lose all Child Benefits, adding an additional tax burden, and pension contributions can help mitigate this.

Student loan repayments further impact graduates’ effective income and can be a significant financial burden.
