Frequently Asked Questions

What’s the difference between marginal and effective rate? Your marginal rate is the bracket your top dollar falls in. Your effective rate is total tax divided by total income — always lower.

Does moving to a higher bracket mean all income is taxed more? No. Only income within each bracket is taxed at that rate. Previous income stays at lower rates.
