Marginal Tax Bracket

Definition of Marginal Tax Bracket

A Marginal Tax Bracket is the section of incremental income on which a designated rate of tax is applied, determined by a progressive tax rate system, wherein higher income levels are taxed at higher rates. Essentially, the marginal tax bracket signifies the rate of tax applied to the last dollar earned, making it distinct from the average tax rate, which is the overall rate applied to the entire income.

Examples

Example 1:
- Assume Morris, a married taxpayer who files a joint return, earns $90,000 annually. He pays $16,000 in federal income taxes, resulting in an average tax rate of 17.8% ($16,000 ÷ $90,000 = 17.8%).
- If Morris earns an additional $1,000, his tax liability increases by $300 because he falls within the 30% marginal tax bracket for that specific dollar amount.
Example 2:
- Jane, who is a single taxpayer, earns $50,000 annually. Her federal income tax payment amounts to $7,500, giving her an average tax rate of 15% ($7,500 ÷ $50,000 = 15%).
- If Jane were to receive a bonus of $5,000, and this additional income places her in a higher tax bracket (22%), she would pay $1,100 ($5,000 × 22%) in taxes on the bonus.
