Effective Tax Rate by Income Level
How the 2025 federal schedule changes by taxable income for a single filer using the standard deduction.
Key findings
- Effective rate is lower than marginal rate. Each rate applies only to the taxable income inside its band, rather than to all income.
- The standard deduction changes the starting point. In 2025, the single standard deduction is $15,750, so gross income and taxable income are not the same figure.
- The table uses the IRS schedule directly. Each completed band shows tax at its upper taxable-income boundary and the corresponding effective rate against gross income after adding back the standard deduction.
- The top marginal rate is not a rate on every dollar. Above the 37% threshold, the effective rate continues to depend on total income and the lower bands already used.
| Taxable Income | Marginal Rate | Approx. Tax Owed | Effective Rate |
|---|---|---|---|
| $0 – $11,925 | 10% | $1,193 | 4.3% |
| $11,925 – $48,475 | 12% | $5,579 | 8.7% |
| $48,475 – $103,350 | 22% | $17,651 | 14.8% |
| $103,350 – $197,300 | 24% | $40,199 | 18.9% |
| $197,300 – $250,525 | 32% | $57,231 | 21.5% |
| $250,525 – $626,350 | 35% | $188,770 | 29.4% |
| $626,350+ | 37% | Varies above this threshold | Varies with income |
Methodology
Effective rate is calculated as total federal income tax divided by gross income. These figures derive from the 2025 single-filer schedule in IRS Revenue Procedure 2024-40 and the $15,750 single standard deduction in the maintained source data. Tax at each completed band is computed from that schedule; the open-ended 37% band varies with income. This is a schedule illustration, not a tax estimate.
