* United Kingdom uses a progressive tax system where each bracket applies only to income within that range.
How Progressive Taxation Works
United Kingdom uses a progressive tax system, meaning your income is taxed in bands or "brackets." Each bracket has its own tax rate, and only the portion of your income within that bracket is taxed at that rate.
This is different from a "flat tax" where all income would be taxed at the same rate. The progressive system means that moving into a higher tax bracket doesn't increase the tax on your previous income—only on the additional amount.
Example: £100,000 Income
