How it works

The standard Part B premium for 2026 is $202.90 a month and the deductible is $283. If your 2024 MAGI was above $109,000 single or $218,000 joint, you pay an income-related monthly adjustment amount (IRMAA) on Part B and Part D.

MAGI here is your AGI plus tax-exempt interest. The top tier, $500,000 single or $750,000 joint, brings Part B to $689.90 a month.

Questions

Can I get IRMAA lowered after I retire?

Yes. File Form SSA-44 after a life-changing event such as stopping work, and Social Security can use your more recent, lower income.

Is Part A free?

For most people. With 40 quarters of work there is no Part A premium; otherwise it costs up to $565 a month in 2026.
