My point is, if you need to use subsidies in 2026 or beyond, you should take advantage of the higher income limits for subsidies in 2024 and 2025, which would mean taking capital gains that would potentially increase your income above the 400% of FPL limit now. If you increase your income over 400% of FPL beginning in 2026, you will have to pay back ALL subsidies. But for 2024 and 2025, you can have income that’s higher than 400% of FPL and you would still get some subsidies. You would probably have to pay back some of the subsidies you’ve received for 2024, and for 2025, you could adjust your income so that you would pay more in premiums. But you need to do the analysis to see if losing some of the subsidies is worth locking in some of your gains. For 2024, you only have a day to make that decision.
If Medicare is 2.5 years away, that means you will be starting Medicare in 2027? If so, Medicare should be on your radar now (or in 3 days, anyway). IRMAA has a 2 year lookback, so your 2025 tax return will be used to calculate IRMAA premiums in 2027.
Edited to add:
For a single taxpayer in 2024, the 0% bracket for capital gains goes up to $47,025 in taxable income. Once you add in the standard deduction of $14,600, that means you would pay $0 in capital gains taxes as long as your total income is less than $61,625. But 400% of FPL for 2024 is $60,240. So to take full advantage of the 0% capital gains bracket, you would exceed 400% of FPL. In 2024 and 2025, you can still get subsidies even when exceeding 400% of FPL. But beginning in 2026, you will have to pay back all subsidies if you exceed 400% of FPL by even $1
For MFJ, you lose even more of the 0% capital gains bracket if you have to remain below 400% of FPL. In 2024, the 0% capital gains bracket tops out at $94,050. Add in the standard deduction of $29,200 and you can have total income of up to $123,050 and not pay any capital gains taxes. But 400% of FPL for a household of 2 is only $81,760 So if you had to stay under 400% of FPL, you would be giving up the opportunity to pay 0% capital gains taxes on over $40,000 in taxable capital gains.
What you need to figure is how much going up to that amount of income will cost in subsidies, and if that’s worth it to lock in capital gains without paying any taxes.
