Medicare Part G premiums are currently tax deductible as a medical expense if you itemize your deductions on your tax return.
Your total medical expenses have to exceed 7.5% of your adjusted gross income (line 11 of your Form 1040) to be deductible. You can only deduct the amount that is above 7.5% of your adjusted gross income.
For example, if your adjusted gross income is $50,000, you cannot deduct the first $3,750 of expenses (7.5% of $50,000). If your total medical expenses are less than $3,750 for this example, your medical expense deduction would be $0. If your total medical expenses were $5,000, your medical expense deduction would be $1,250.
