Understanding Adjusted Gross Income (AGI)
Adjusted Gross Income (AGI) is a measure of your total income used to determine how much of your income is taxable. It's calculated by subtracting certain "above-the-line" deductions from your gross income before applying the standard deduction or itemized deductions.
What is AGI?
AGI represents the total income you earned during the tax year, minus certain adjustments. It's an important figure because many tax credits, deductions, and other tax benefits are based on your AGI amount.
AGI = Gross Income - Above-the-Line Deductions
Above-the-Line Deductions
These are deductions you can take from your gross income to arrive at AGI. Unlike itemized deductions, you don't need to itemize to claim these.
Common Adjustments
- IRA Contributions: Traditional IRA contributions
- Student Loan Interest: Up to $2,500 per year
- Health Savings Account: HSA contributions
- Educator Expenses: Up to $250 for teachers
- Self-Employed Health Insurance: Premiums paid
Less Common Adjustments
- Self-Employed Retirement: SEP-IRA, SIMPLE plans
- Moving Expenses: Qualified military moves
- Alimony Paid: Under pre-2019 divorce decrees
- Domestic Production: Business activity deductions
Why AGI Matters
| Tax Benefit | AGI Threshold | Impact |
|---|---|---|
| Earned Income Tax Credit | $16,690 (single) | Credit phases out above threshold |
| Child Tax Credit | $400,000 (married) | Credit reduces above threshold |
| Medical Expense Deduction | 7.5% of AGI | Must exceed threshold to deduct |
| Net Investment Income Tax | $200,000 (single) | 3.8% tax applies above threshold |
AGI vs. Taxable Income
While AGI is an important intermediate calculation, your final taxable income is determined by subtracting either the standard deduction or itemized deductions from your AGI.
Taxable Income = AGI - Standard Deduction (or Itemized Deductions)
