On Medicare it is important to note that the surcharges are calculated based on a two year loopback on reported income. So basically something to monitor in the year you are 63.



The Social Security Administration (SSA) determines if you owe an IRMAA based on the income you reported on your IRS tax return two years prior, meaning two years before the year when you pay the IRMAA. For example, Social Security would use tax returns from 2022 to determine your IRMAA in 2024.
