Marginal vs Effective Tax Rate
Progressive systems tax income in brackets — only income in each bracket is taxed at that rate.
| Concept | Definition |
|---|---|
| Marginal rate | Tax on the next dollar you earn |
| Effective (average) rate | Total tax ÷ total income |
Your marginal rate matters for extra work; your effective rate describes overall burden.
Deductions and Credits
Deductions reduce taxable income (e.g. standard vs itemized). Credits reduce tax owed dollar-for-dollar — often more powerful.

Withholding from paychecks is a prepayment — your true liability is settled at year-end (refund or payment). Bonuses and side income can change the picture.
