Key Terms Glossary

Adjusted Gross Income (AGI)
Your total gross income minus specific deductions (like student loan interest, IRA contributions, and HSA contributions). AGI is used to determine eligibility for many tax credits and deductions.
Marginal Tax Rate
The tax rate applied to your last dollar of income. The U.S. uses a progressive system where higher portions of income are taxed at higher rates. Your marginal rate is not the rate on all your income.
Effective Tax Rate
The actual percentage of your total income that you pay in taxes. Calculated by dividing your total tax liability by your total income. This is always lower than your marginal rate.
Standard Deduction
A fixed dollar amount that reduces the income on which you are taxed. For 2026, the standard deduction is $15,000 for single filers and $30,000 for married filing jointly (estimated, subject to IRS updates).
Capital Gains
The profit from selling an asset (stocks, real estate, etc.) for more than you paid. Short-term gains (held less than a year) are taxed as ordinary income; long-term gains (held over a year) receive preferential lower rates.
Self-Employment Tax
A tax of 15.3% (12.4% Social Security + 2.9% Medicare) on net self-employment earnings. Employees split this with employers, but self-employed individuals pay both halves. You can deduct half of this tax on your return.
Withholding
The amount your employer deducts from each paycheck to prepay your income taxes. The amount depends on your W-4 form selections, income level, and filing status.
