How to appeal IRMAA, and when not to

Got an IRMAA letter you think is wrong? There are two different fixes, and picking the right one matters more than anything you write. Most people don't need an appeal at all.

Do this today

Find the date printed on your letter. Your appeal deadline is 60 days after you got it, and Social Security assumes you got it 5 days after that date. So you have about 65 days from the date on the letter. Put it in your calendar.

Step 1: pick the right fix

Which IRMAA fix to use
Your situationWhat to do
Your income dropped because you retired, cut back work, married, divorced, lost your spouse, or lost a pensionFile Form SSA-44. It isn't an appeal: it asks for a new decision using your lower, newer income.
Social Security used the wrong income, the wrong tax year, or the wrong filing statusAsk for reconsideration with Form SSA-561-U2, with proof.
You amended your tax return, or the IRS has the wrong figuresCorrect the tax data: send the amended return and the IRS acknowledgment. Call Social Security for this one.
Your income was high from a Roth conversion, a home sale, or a one-time gainNo form can fix it. The charge ends on its own once that year's income is no longer used, two years later.

Social Security's own staff manual notes that a new request often gets you the result you want, which makes an appeal unnecessary. If something was missing or wrong on your side, fix it and file again.

Step 2: read the letter

Why IRMAA requests get refused, and the fix

Common refusal reasons and fixes
What the letter saysWhat to do
No proof of the event, or it didn't arriveFile a new SSA-44 with the document. This is the most common reason, and the easiest to fix.
No proof of incomeSend a signed copy of your tax return or an IRS transcript for the year you asked them to use.
The tax year can't be usedThe year must be more recent than the one they used, and not before your event. File again with the right year.
Not a life-changing eventIf they misread your event, ask for reconsideration with proof. A Roth conversion or home sale can't be fixed with any form: the charge ends when that year's income stops being used.
Your new income is still over the lineRecheck your MAGI: Form 1040 line 11 plus line 2a. If the figures were wrong, file again. If they're right, your bracket can't change.
The IRS figures don't match yoursAmended your return? Ask for a new decision with the amended return and the IRS letter acknowledging it. If the IRS has wrong figures, contact the IRS first.

How to ask for reconsideration

  1. Get Form SSA-561-U2"Request for Reconsideration" is free from ssa.gov, or ask your local office. You can also start an appeal online.
  2. Say what you disagree withOne or two sentences: the date of the letter, the premium year, the tax year and income you want used, and why.
  3. Attach your proofCopies of your SSA-44 (if you filed one), your proof of the event and of your income, and anything that answers the reason in the letter.
  4. Send it within 60 daysTo your local office (find it with the office locator), by certified mail, fax or in person. Keep a copy and proof of sending.
  5. Keep paying while you waitIf you win, the lower amount generally applies from January of the premium year, and the difference comes back for Part B and Part D.

Sample statement

"I do not agree with the determination dated [date] about my income-related monthly adjustment amount for [premium year]. On [date] I reported a life-changing event, [event] in [mm/yyyy], on Form SSA-44, and asked you to use my [tax year] modified adjusted gross income of [$ amount]. I am enclosing [document], which shows [what it proves]. Please reconsider and use my [tax year] income."

If reconsideration also says no

Ask for a hearing before an administrative law judge with Form HA-501-U5. For IRMAA, the judges work for the Office of Medicare Hearings and Appeals at the Department of Health and Human Services. Want someone to represent you? They need Form CMS-1696. After the hearing come the Medicare Appeals Council and then federal court.

Questions people ask

How long do I have to appeal IRMAA?

60 days from when you get the decision letter. Social Security assumes you got it 5 days after the date printed on it, so in practice about 65 days from that date. Late appeals can be accepted for good cause.

Is Form SSA-44 an appeal?

No. SSA-44 asks for a new decision because your income dropped after a life-changing event. An appeal (reconsideration) says the decision itself was wrong. If you retired or had another life-changing event, SSA-44 is usually the right tool.

Which form do I use to appeal IRMAA?

Form SSA-561-U2, Request for Reconsideration. Send it to your local Social Security office, or start the appeal online.

Do I keep paying IRMAA while I appeal?

Yes. Keep paying as billed so your coverage doesn't end. If you win, the lower amount generally applies from January of the premium year and the difference is refunded or credited.

What if reconsideration says no?

You can ask for a hearing before an administrative law judge with Form HA-501-U5. For IRMAA, the judges are at the Office of Medicare Hearings and Appeals in the Department of Health and Human Services.
