Apologies if this has been covered, couldn't find it searching the archive.
I'm doing some end of the tax year planning. With my current artificially-low FIRE income (a little from consulting plus some dividends and cap gains), I would get $5k in ACA premium tax credits back. However, if I take advantage of the "harvest your capital gains and pay no tax if you stay in the 10% or 15% bracket" strategy, I can harvest $70k in tax-free capital gains from my investments. Doing so would push my income above 400% FPL, and I would lose the $5k PTC. But, on paper at least, the tax-free $70k gains would be worth more than $7k (assuming it were otherwise taxed in the 10% bracket when realized and taxed in the future, more because some of it would likely be in the 15%).
So my decision seems to be
1) $5k cash in hand now by claiming the PTC
2) $7k+ paper tax savings by cashing out gains instead
The math says it is worth $2k to forego the PTC and max out the harvested capital gains. Am I missing something?
