Can I appeal an IRMAA determination?

Yes. If your income has decreased significantly due to a qualifying life-changing event (retirement, reduced work hours, marriage, divorce, death of spouse, loss of pension, or loss of income-producing property), you can file SSA Form SSA-44 to request that SSA use more recent income. If approved, your IRMAA can be reduced retroactively.

What is the IRMAA cliff effect?

IRMAA operates in brackets similar to tax brackets, but unlike marginal tax rates, IRMAA surcharges apply to your entire premium once you cross a threshold, not just the income above it. This creates a 'cliff' effect where earning one dollar more than a threshold can cost thousands in additional annual premiums.

How are IRMAA surcharges calculated for married couples?

For married couples, the IRMAA surcharge is based on the couple's combined income. If the combined income is above $182,000, the couple will pay an additional $68.80 to $356.40 per month for Medicare Part B, and $12.40 to $76.40 per month for Medicare Part D, depending on their income level. The exact surcharge amount will depend on the couple's specific income and tax filing status.

Can life-changing events affect my IRMAA surcharge?

Yes, certain life-changing events, such as marriage, divorce, or the death of a spouse, can affect your IRMAA surcharge. For example, if you get married and your combined income increases, you may be subject to a higher IRMAA surcharge. You should report any changes to the Social Security Administration to ensure your IRMAA surcharge is adjusted accordingly. This can help you avoid overpaying or underpaying your Medicare premiums.

How often can my IRMAA surcharge change?

Your IRMAA surcharge can change annually, based on your income from two years prior. For example, your 2024 IRMAA surcharge will be based on your 2022 income. If your income has changed significantly, you may be eligible for a lower or higher IRMAA surcharge. You will receive a notice from the Social Security Administration each year indicating whether your IRMAA surcharge will increase, decrease, or remain the same.
