If you don't sign up for Part B when you're first eligible, you may have to pay a late enrollment penalty.
How much does Part B cost?
Part B premiums
You pay a premium each month for Part B. Your Part B premium will be automatically deducted from your benefit payment if you get benefits from one of these:
- Social Security
- Railroad Retirement Board
- Office of Personnel Management
If you don’t get these benefit payments, you’ll get a bill.
Most people will pay the standard premium amount. If your modified adjusted gross income is above a certain amount, you may pay an Income Related Monthly Adjustment Amount (IRMAA). Medicare uses the modified adjusted gross income reported on your IRS tax return from 2 years ago. This is the most recent tax return information provided to Social Security by the IRS.
The standard Part B premium amount in 2018 will be $134 (or higher depending on your income). However, some people who get Social Security benefits pay less than this amount ($130 on average). You'll pay the standard premium amount (or higher) if:
- You enroll in Part B for the first time in 2018.
- You don't get Social Security benefits.
- You're directly billed for your Part B premiums (meaning they aren't taken out of your Social Security benefits).
- You have Medicare and Medicaid, and Medicaid pays your premiums. (Your state will pay the standard premium amount of $134.)
- Your modified adjusted gross income as reported on your IRS tax return from 2 years ago is above a certain amount. If so, you'll pay the standard premium amount and an Income Related Monthly Adjustment Amount (IRMAA). IRMAA is an extra charge added to your premium.
