📋 Data Entry
The US uses a progressive tax system: income is divided into brackets, and each portion is taxed at a different rate. Your marginal rate is the rate of your highest bracket; your effective rate is the actual percentage you pay overall.
Example: a single filer earning $60,000 doesn't pay 22% on the whole amount. They pay 10% on the first $11,925, 12% on the next portion, and 22% only on income above $48,475.
Standard vs. Itemized: most filers take the standard deduction (it's higher and simpler). Itemize only if your deductible expenses (mortgage interest, SALT capped at $10K, charitable gifts, medical) exceed the standard amount.
