Ok, let me give you another scenario.
in 2020 lets say I paid 30k in taxes.
in the first quarter of 2021, lets say I already have 400k of capital gains, which at 15% means I owe 60k in taxes.
So are we saying if I submit a payment of 30k, I will avoid underpayment penalty? But obviously I will be subjec to the interest rate charge at the end of the year.
