Understanding AGI and Your Medical Threshold

How AGI is calculated, what above-the-line deductions reduce it, and why a lower AGI can make medical expenses suddenly deductible.

📚Key Terms & DefinitionsPlain English

Adjusted Gross Income (AGI)

Your total gross income minus above-the-line deductions. Found on Line 11 of Form 1040. The number used to calculate your 7.5% medical expense threshold.

Above-the-Line Deduction

A deduction subtracted from gross income before arriving at AGI — available even if you take the standard deduction. Examples: IRA, SE health insurance, HSA contributions.

Standard Deduction (2024)

$14,600 (single), $21,900 (head of household), $29,200 (married filing jointly). If you take it, you cannot also claim Schedule A medical expenses.

Itemized Deductions

Specific deductions on Schedule A: medical expenses above 7.5% AGI, state/local taxes (capped at $10,000), mortgage interest, and charitable contributions.

SALT Cap ($10,000)

The TCJA limits the combined deduction for state income taxes and property taxes to $10,000 per return. The medical deduction is separate and has no cap.

Unreimbursed Medical Expense

Medical costs you paid out of pocket that weren’t covered by insurance, an HSA, or FSA. Only unreimbursed amounts count toward the 7.5% AGI threshold.

HSA (Health Savings Account)

Tax-advantaged account for HDHP enrollees. Contributions are pre-tax, growth is tax-free, and qualified withdrawals are tax-free. Expenses paid from an HSA cannot also appear on Schedule A.

FSA (Flexible Spending Account)

Employer-sponsored pre-tax account for medical or dependent care spending. Like HSAs, FSA-reimbursed expenses cannot be deducted again on Schedule A.

Self-Employment (SE) Tax

The 15.3% tax paid by 1099 workers in place of employer/employee FICA. The IRS allows you to deduct exactly half above the line as an AGI reduction.

Medical Mileage Rate (2024)

21 cents per mile for travel to and from medical appointments. Parking and tolls are also deductible. Keep a log with date, destination, and medical purpose.

Modified AGI (MAGI)

AGI with certain deductions added back — used for Roth IRA eligibility, premium tax credits, and other benefit thresholds. Slightly different from the AGI used for the medical threshold.

Long-Term Care Insurance Premiums

Deductible as a medical expense, subject to age-based IRS limits. For 2024, the max deductible premium is $5,880 for taxpayers age 71+. Counts toward the 7.5% AGI threshold.
