Your employer or pension provider uses something called PAYE (Pay As You Earn). They automatically split your salary into two chunks: the tax-free bit and the taxable bit. You don’t have to fill out confusing forms—it just happens.
Here’s the fun part: if you earn less than £12,570 in a year, you pay zero income tax. Zip. Nada. That’s like being given a “no entry” sign for the taxman—pretty sweet, right?
But wait—what if you earn more? Only the extra money above £12,570 gets taxed. So if you earn £20,000, you only pay tax on the remaining £7,430. It’s not a tax on everything—just the party after the free buffet.
