Two taxes affect almost everyone: VAT (when buying things) and income tax (when earning money). Here's the essentials.

VAT: standard rates around the world

EU standard: 17-27% (Spain 21%, Germany 19%, France 20%, Hungary 27%).

UK: 20% standard, 5% reduced, 0% essentials.

US: no federal VAT — sales tax varies by state (0-10%).

To add VAT: price × (1 + rate/100). To remove it: price / (1 + rate/100).

How income tax actually works

Income tax is progressive: marginal rates apply to slices of income, not the whole. Your "effective rate" (what you actually pay on total income) is always lower than your "marginal rate" (what you pay on the next dollar earned).

Example US federal brackets 2024 (single):

Up to $11,600: 10%

$11,600 – $47,150: 12%

$47,150 – $100,525: 22%

$100,525 – $191,950: 24%

$191,950 – $243,725: 32%

If you earn $80,000, your marginal rate is 22% but your effective rate is around 15-17% (before deductions).
