Medical Expense Deduction Calculator
for 1099 Contractors
As a 1099 worker, you pay your own insurance, carry your full medical costs, and pay 15.3% in self-employment tax. The tax code compensates you with three medical-related deductions that W-2 employees simply don’t get — but only if you know how to stack them.
This calculator handles all three: the SE tax deduction, the above-the-line health insurance premium deduction, and the Schedule A medical deduction. Enter your numbers — we’ll show your full picture in under two minutes.
The 3-Layer Medical Deduction Stack for 1099 Workers
Enter your net 1099 income, health insurance premiums, and out-of-pocket medical costs — we’ll calculate all three deductions and your combined tax savings.
Why 1099 Workers Have More Medical Deduction Options
W-2 employees can only deduct medical expenses exceeding 7.5% of AGI on Schedule A — and only if they itemize. As a 1099 contractor you have that same option plus two additional above-the-line deductions: the 50% SE tax deduction and the health insurance premium deduction. Both reduce your AGI before the 7.5% calculation starts, making the Schedule A deduction more accessible. See IRS Publication 502 and Schedule 1 instructions for the official rules.
The SE Tax Deduction — An Automatic Benefit
1099 workers pay self-employment tax (15.3% up to the Social Security wage base) in place of the employer and employee FICA contributions. The IRS lets you deduct exactly 50% of this tax above the line on Schedule 1. On $70,000 in net SE income, the SE tax is roughly $9,890 and the deductible half is about $4,945. This reduction flows directly into your AGI calculation — no paperwork beyond Schedule SE, which TurboTax and most tax software auto-generate.
The Health Insurance Premium Deduction
If you pay your own health, dental, and vision insurance and aren’t eligible for an employer plan (yours or a spouse’s), you can deduct 100% of those premiums on Schedule 1, Line 17. The deduction is capped at your net self-employment profit — it can’t create a loss. This deduction doesn’t require itemizing. It stacks on top of the SE tax deduction to further lower your AGI before the 7.5% medical floor is calculated.
Retirement Contributions Triple the Benefit
SEP-IRA, Solo 401(k), and HSA contributions all reduce AGI above the line too. A 1099 worker who contributes $10,000 to a SEP-IRA, deducts $6,000 in premiums, and takes the SE tax deduction on $80K of income could bring their effective AGI to $55,000 — dropping the 7.5% medical floor from $6,000 to $4,125. Every AGI-reducing contribution compounds with the others.
What Out-of-Pocket Costs Count on Schedule A
After all above-the-line deductions reduce your AGI, out-of-pocket medical costs above 7.5% of that reduced figure are deductible on Schedule A. This includes doctor visits, dental care, prescriptions, mental health therapy, medical mileage at 21¢/mile, and durable medical equipment. Premiums already deducted above the line cannot appear on Schedule A — no double-dipping.
