Investors & landlords

Thanks for the response!

Sorry. I used confusing terminology.

What I should have said is that I am contemplating realizing all $227,000 in long term Capital Gains in calendar year 2020  when I have no earned income in anticipation that the net tax rate on the long term gain would be ZERO.

 

I ran this through the Tax Caster as suggested and added the following relevant information:

Head of Household

1 dependent under 13

$19,000 Mortgage interest

$4,500 Property tax

$2,000 Charitable

 

The result was:

2018 Estimated Federal Amount Owed

(After Tax Reform)

$23,508
 
Therefore, it seems that there must be some Cap on the amount of long term Capital Gains that can be realized at the 0% rate, but I cannot determine the calculation. 
Potentially, I could spread the gain over more years at the 0% rate  if I understood the calculation methodology.
