How US Federal Income Tax Works
The US uses a progressive marginal tax system — you do NOT pay your top bracket rate on all your income. Each bracket's rate applies only to income within that range. Understanding this distinction prevents a common misconception: moving into a higher bracket doesn't mean your entire income is taxed at the higher rate.
