Tax-free allowance
In short
The amount of income that is not taxed at all.
The tax-free allowance is an amount set by law. You pay no tax on the money that falls within it.
The amount can change with your family situation, for example if you have children.
You only pay tax on the part of your income above the tax-free allowance, following the brackets.
