Medical Expense Deduction Calculator
for New Jersey Residents
New Jersey has its own medical expense deduction rules — and they differ meaningfully from federal. The NJ threshold is 2% of gross income (vs. federal’s 7.5% of AGI), NJ excludes Social Security from gross income, and NJ doesn’t follow all of the same expense rules.
This calculator runs both your federal and NJ state deductions side by side, so you know exactly what to claim on each return.
Federal vs. New Jersey Medical Deduction Rules
Enter your federal AGI, your NJ gross income, and your medical costs — we’ll calculate both your federal and NJ deductions.
How New Jersey’s Medical Deduction Differs From Federal
New Jersey does not conform to the federal tax code in several important ways. For medical deductions, the most significant differences are the income base and the threshold rate. Federally, you need to clear 7.5% of your Adjusted Gross Income — a figure that includes wages, retirement income, and the taxable portion of Social Security. New Jersey uses 2% of NJ gross income, which sounds more generous, but NJ gross income is often higher than federal AGI because NJ doesn’t allow the same above-the-line deductions.
However, for retirees, NJ is nearly always more favorable: New Jersey does not tax Social Security benefits at all. A retiree with $30,000 in Social Security and $30,000 in IRA withdrawals has a federal AGI of roughly $55,500 (with 85% of SS taxable) but a NJ gross income of only $30,000 — creating a far lower NJ threshold.
New Jersey’s Property Tax Situation and Medical Deductions
New Jersey has the highest property taxes in the nation — the average NJ homeowner pays over $9,000/year. On the federal return, you can deduct up to $10,000 in combined state and local taxes (SALT) on Schedule A. This is separate from the medical expense deduction, which has its own line and its own calculation. If your property taxes are already consuming the $10,000 SALT cap, the medical deduction becomes even more important as an additional itemized deduction.
On the NJ state return, property taxes are handled separately from the medical deduction — through the NJ property tax deduction or the property tax credit. Your medical deduction on NJ Schedule A is calculated independently.
The NJ ANCHOR Benefit and Taxes
The ANCHOR property tax relief program provides NJ homeowners and renters with property tax relief payments. These payments are generally not taxable for NJ purposes and do not affect your NJ gross income or your medical deduction calculation. For federal purposes, ANCHOR payments are state relief payments similar to rebates and are generally not includable in federal gross income either — but confirm with a tax professional if your situation is complex.
What Qualifies as a Medical Deduction in NJ?
New Jersey generally follows the federal definitions of qualified medical expenses from IRS Publication 502 for what counts. Doctor visits, dental care, vision, prescriptions, medical equipment, and medical transportation all qualify on both returns. Health insurance premiums are deductible in NJ, but not if they’re being deducted through an employer plan or if they were excluded from income through a Section 125 cafeteria plan — the same double-dip restriction that applies federally.
NJ-Specific Pension and Retirement Income Exclusions
NJ offers a pension income exclusion for certain taxpayers: up to $100,000 of pension, annuity, and IRA income can be excluded from NJ gross income for married couples filing jointly if their total income is $100,000 or less. This exclusion, if applicable, can significantly lower your NJ gross income and therefore lower your 2% medical deduction threshold — making it easier to qualify.
