Example Tax Calculation
See how a $75,000 salary for a Single filer is taxed.
Step 1: Adjusting Income
Gross ($75,000) - 401k ($5,000) = $70,000 AGI
AGI ($70,000) - Standard Deduction ($15,000) = $55,000 Taxable Income
Step 2: Federal Brackets
- 10% on first $11,925 = $1,192.50
- 12% on next $36,550 = $4,386.00
- 22% on remaining $6,525 = $1,435.50
- Total Fed Tax = $7,014.00
Step 3: FICA & State
Frequently Asked Questions
Marginal vs. Effective Rate?
Marginal rate is the tax percentage on your last dollar earned. Effective rate is the weighted average — the percentage of your total income that goes to taxes.
What is AGI?
Adjusted Gross Income (AGI) is your gross income minus specific adjustments like 401k contributions or HSA payments. It is the starting point for calculating your tax liability.
Standard or Itemized?
Most filers take the standard deduction. You should only itemize if your qualified expenses (mortgage interest, charity, medical) exceed the standard deduction amount for your status.
What are FICA taxes?
FICA consists of Social Security and Medicare taxes. These are mandatory payroll taxes withheld from almost every paycheck in the United States to fund these federal programs.
How can I reduce my tax bill?
The easiest way is through pre-tax contributions. Funding a 401k, 403b, or Traditional IRA reduces your AGI dollar-for-dollar, lowering your taxable income.
