Quick Answer
The 7.5% AGI threshold means you can only deduct medical expenses that exceed 7.5% of your adjusted gross income. If you earn $80,000, you need more than $6,000 in medical expenses to get any deduction. Only amounts above $6,000 are deductible—so $8,000 in expenses would give you a $2,000 deduction.

Taxpayers trying to understand how the medical expense threshold affects their potential deduction
How the 7.5% AGI threshold works
The 7.5% adjusted gross income (AGI) threshold is a floor—you must exceed this amount before any medical expenses become deductible. According to IRS Publication 502, this threshold prevents small, routine medical expenses from being deducted.
The calculation is straightforward:
1. Find your AGI (line 11 on Form 1040)
2. Multiply AGI × 7.5% = your threshold
3. Subtract the threshold from total medical expenses
4. The remainder is your deductible medical expense
Formula: Deductible medical expenses = Total medical expenses - (AGI × 0.075)
Example: Three different income levels
Here's how the threshold affects taxpayers at different income levels:
Notice how the same $5,000 in medical expenses results in vastly different deductions based on income.
Detailed example: $75,000 income with major medical year
Let's say you earn $75,000 AGI and have these medical expenses:
Calculation:
This $11,375 deduction could save you $2,730-$4,208 in taxes, depending on your tax bracket (24% to 37%).
Why the threshold exists
The IRS instituted this threshold to:
Historical context: The threshold was 10% of AGI from 2013-2016, then permanently reduced to 7.5% starting in 2017. This change made medical deductions more accessible.

What counts toward the threshold
All qualifying medical expenses count toward reaching the 7.5% threshold:
Important: Expenses reimbursed by insurance don't count. Only your actual out-of-pocket costs matter.
What you should do
If you're close to the 7.5% threshold:
1. Calculate your exact threshold based on this year's AGI
2. Add up all qualifying medical expenses paid this year
3. Consider accelerating planned medical expenses into this tax year
4. Use our refund estimator to see if itemizing with medical expenses beats the standard deduction
Key takeaway: The 7.5% AGI threshold means higher earners need substantial medical expenses to benefit. Someone earning $100,000 needs more than $7,500 in medical expenses before any become deductible.

Basic taxpayers who want to understand if their medical expenses are worth tracking
Should you bother tracking medical expenses?
For most simple filers, the 7.5% AGI threshold makes medical deductions challenging to use effectively. Here's the reality check:
Quick threshold calculation:
Most routine medical costs won't help:
When medical deductions DO make sense for simple filers:
Example: $45,000 earner with $6,000 in medical expenses
Bottom line: Unless you have a major medical event, focus on maximizing HSA or FSA contributions rather than tracking expenses for potential deductions.
Key takeaway: Simple filers should track medical expenses only during years with major medical events—routine healthcare rarely exceeds the 7.5% threshold.

Homeowners who may already itemize and want to add medical expenses to their deductions
Medical deductions when you already itemize
As a homeowner who likely itemizes for mortgage interest and property taxes, adding medical expenses above the 7.5% AGI threshold can provide additional tax savings.
Your advantage: You're already itemizing, so every dollar of medical expenses above the threshold directly reduces your taxable income.
Example homeowner scenario:
Now add medical expenses:
Tax savings: The additional $2,825 in medical deductions saves $678-$1,014 in taxes (24%-32% tax brackets).
Medical expenses homeowners often overlook:
Strategic timing for homeowners:
Record keeping: Since you're already maintaining itemized deduction records, adding medical expense documentation is straightforward.
Key takeaway: Homeowners who itemize can benefit from medical expenses above 7.5% of AGI since they don't need to exceed the standard deduction threshold.
Key Takeaway: Homeowners who itemize can benefit from medical expenses above 7.5% of AGI since they don't need to exceed the standard deduction threshold.
