Long term capital gains, of course, are taxed at favorable rates as compared with ordinary income.
So thoughts about long term capital gains might generally lean in the direction of puppies, cookies, and beautiful sunny days . . . in short, good things. There is ample reason for this, but not when it comes to the dreaded IRMAA.
As those with experience already know, the IRMAA takes no prisoners. But you might not be aware the IRMAA also gives no quarter when you show up with long term capital gains. So while you might have warm and fuzzy feelings about capital gains generally, and feel safe, the IRMAA will spit in your face, grab you by the ankles hoisting you skyward, and collect your money as it drops unavoidably from your pockets.
In short, be real careful. Long term capital gains, whether from sale of stock, a home, or whatever else, can easily drive you into a higher IRMAA tax bracket and cost you significant money, catching you unaware at the same time. Be on alert and don’t let this happen to you unknowingly.
