Deduct premiums you paid for health insurance for yourself, your spouse, and your dependents if those premiums haven't already been deducted or excluded from your income.

If you claimed a deduction for health insurance premiums as an Itemized Deduction on the federal portion of your return, use the worksheets below to calculate the deduction allowed for health insurance premiums. The worksheets follow the priority that Itemized Deductions first apply to health insurance premiums, then to long-term care insurance.

Idaho Medical Savings Account
If you take money out of your Idaho medical savings account to pay medical insurance premiums, no deduction is allowed. Since the health insurance costs are already deducted or accounted for, they can't be deducted a second time.

Salary Reduction Plans
Premiums paid through a cafeteria plan or other salary-reduction arrangement can't be included in the Idaho deduction for health insurance costs. For example, if your health insurance payments are deducted from your paycheck pretax, they don't qualify for the deduction.

Business Deductions
Premiums deducted as a business expense can't be included in the Idaho deduction for health insurance costs since these amounts are already deducted.

Social Security Medicare A and B
No deduction is allowed for the amount paid for employer required Social Security Medicare A. This is the amount listed as a deduction on almost every federal Form W-2 (W2).

If you voluntarily enroll in Medicare B or Medicare D, or aren't covered under Social Security and voluntarily enroll in Medicare A, the premiums you paid may be deducted.

Idaho Standard Deduction
If you don't itemize deductions for Idaho income tax purposes, but instead use the Idaho Standard Deduction, you don't have to reduce your health insurance costs by any amount claimed as a federal Itemized Deduction.

Federal Itemized Deduction Limitations
For federal purposes, the amount of medical expenses allowed as a deduction on the federal Form 1040, Schedule A, is required to be reduced by 7.5% of adjusted gross income. The following worksheet shows how the limitation of the 7.5% of adjusted gross income required for federal purposes affects the amount of health insurance costs deductible for Idaho purposes.

If you aren't itemizing deductions for Idaho, skip lines 1-6 and enter zeros on lines 8, 12, and 13.
