Sort of but maybe not that much. You could, for example, take out a chunk, ride a few years with subsidies, then take another chunk, pay full freight for one year, rinse/repeat. It might make better sense to pay the subsidies some years vs a massive tax bill. Also, look for all the appropriate deductions - for example we have a HD/HSA plan so we have a large deductible, but that means another $6500 ish reduced from income.
And yes, we did sell a lot of low-hanging-fruit the year before we started the ACA, and might have to plan for that if we need to sell and create a lot of cap gains some year down the road. But, watch this space, as the subsidies (and the cliff) have changed temporarily with the Covid relief bills, and might again with future legislation.
