Couple is in the 22% marginal tax rate based off retirement income, SS, and normal dividends. They are looking at cashing out of a couple of rentals that will produce a long term capital gain of ~$400K to ~$900K depending on what they sell. 1031 is not considered so the gain will be realized.
I know the 3.8% investment tax will kick in as well as IRMAA increase in two years for the one year til their income goes back down to the first increment and they return to the 22% marginal bracket.
I am struggling to understand how the overall income lines up with the marginal tax rate. Can someone explain to me the impact of a large capital gain may have on overall marginal tax rate?

Roughly:
1. Take their ordinary income (SS, W-2, Schedule C, interest, ordinary dividends) and stack that up.
2. Take their capital gains and stack that on top of the ordinary income.
3. Take their standard or itemized deduction from the bottom of the pile (so it eats up ordinary income first then may eat up capital gains second).
4. Apply the ordinary income tax brackets to any remaining ordinary income.
5. Apply the capital gains tax brackets to any remaining capital gain income, taking into account that the ordinary income takes up room in the capital gains brackets (So even though the first ~$94K is 0% LTCG bracket, if they have $94K in ordinary income, their first LTCG dollar starts in the 15% bracket).
6. Apply NIIT to any NII above the cutoff amount ($200K single, $250K married).
It does get more complicated if there is depreciation recapture or other stuff going on.
There is also an additional Medicare tax (separate from NIIT). I don't know much about it but it may hit the couple you're talking about with that level of capital gain.
With that much capital gain and any reasonable amount of ordinary income, you can probably count on most of the RE LTCG getting taxed at 15%, some at 18.8% (15% LTCG plus 3.8% NIIT), and maybe even some at 23.8% (20% LTCG plus 3.8% NIIT).
They probably should consider selling the properties off one at a time across multiple tax years if that works for them. $400K LTCG in two tax years each maybe saves 5% compared to $800K in one tax year (because you can shift anything that was in the 20% LTCG bracket down into the 15% LTCG bracket).
The CSS spreadsheet would do a good job modeling all this too.
