Understanding Tax Terms
Gross Income:
Your total income before any deductions or taxes. Includes wages, salaries, bonuses, tips,
investment income, and other sources of income.
Adjusted Gross Income (AGI):
Gross income minus specific deductions like IRA contributions, student loan interest, and HSA
contributions. AGI determines eligibility for many tax benefits.
Standard Deduction:
A fixed dollar amount that reduces your taxable income. Most taxpayers claim the standard deduction
rather than itemizing. Amount varies by filing status.
Itemized Deductions:
Alternative to standard deduction. Include mortgage interest, property taxes (up to $10,000),
charitable donations, and medical expenses over 7.5% of AGI.
Taxable Income:
AGI minus deductions and exemptions. This is the amount used to calculate your tax liability based
on the tax brackets.
Marginal Tax Rate:
The tax rate you pay on your last dollar of income. This is the highest tax bracket your income
reaches. Important for evaluating raises or bonuses.
Effective Tax Rate:
Your total tax divided by gross income. This is your actual average tax rate and is always lower
than your marginal rate due to progressive brackets.
FICA Taxes:
Federal Insurance Contributions Act taxes fund Social Security (6.2%) and Medicare (1.45%).
Additional 0.9% Medicare tax applies to income over $200,000.
Example Tax Calculation
Scenario:
Filing Status: Single
Gross Income: $75,000
Standard Deduction: $14,600
Taxable Income: $60,400
Federal Tax Calculation:
10% on first $11,600 = $1,160
12% on next $35,550 ($47,150 - $11,600) = $4,266
22% on next $13,250 ($60,400 - $47,150) = $2,915
Total Federal Tax: $8,341
FICA Taxes:
Social Security: $75,000 × 6.2% = $4,650
Medicare: $75,000 × 1.45% = $1,088
Total FICA: $5,738
Total Tax: $14,079 (18.8% effective rate)
Take-Home Pay: $60,921
