Income tax is a government levy on personal earnings, calculated using progressive tax brackets where higher portions of income are taxed at increasing rates.
IRA, HSA, student loan interest, etc.
effective rate: 12.4%
| Bracket | Rate | Taxable | Tax |
|---|---|---|---|
| $0: $11,600 | 10% | $11,600.00 | $1,160.00 |
| $11,600: $47,150 | 12% | $35,550.00 | $4,266.00 |
| $47,150: $100,525 | 22% | $23,250.00 | $5,115.00 |
Formula
Tax = Σ (Income in Bracket × Bracket Rate) − CreditsAGI = Adjusted Gross Income = Gross Income − Above-the-line deductions
Taxable Income = AGI − Standard or Itemized Deduction
Effective Rate = Total Tax ÷ Gross Income × 100
Worked Example
Single filer, $85,000 gross, standard deduction, no credits
Did you know? The US uses a progressive tax system: only the dollars in each bracket are taxed at that rate, not your entire income. A $1 raise never puts all your income into a higher bracket.
