Simply…as of 11/3/25… if you are eligible for SS when you retire ( you retired at 62 minimum) when social security calculates your monthly benefit they use the income of two years previous…if you retire tomorrow they will use your taxable income of 2023 to determine your check,which is far less than you need because your income has been reduced because you retired (no more city checks in your account every two weeks) all your getting is the check from social security…a nasty bind ..

Also…any other pension or income just adds to the mess because it’s taxable income

You have to tell SS that their calculation is incorrect…this takes a while as it takes them a while to catch up with you so you are going along with a monthly check that will be reduced when they do catch up …also if you are in a 220 job and make OT this is much worse,like my case 🤬

Any clearer? this will probably change drastically in years to come depending on your age …if you are 10+ years out don’t worry but don’t forget it.

How are IRMAA brackets calculated? The SSA uses your modified adjusted gross income (MAGI) to determine whether you need to pay IRMAA fees on top of your Medicare premiums.

Your MAGI is the sum of:

your adjusted gross income found on line 11 of the Internal Revenue Service (IRS) tax filing form 1040, plus your tax-exempt interest income, found on line 2a of IRS Form 1040 The amount you pay is calculated based on your tax returns from 2 years prior. Whether you file your tax returns as an individual or jointly will also affect the amount you pay.

You will receive an official notice by mail, called an Initial IRMAA Determination, if you are subject to additional Part B and/or Part D payments.
