Hello, what is the deadline for making estimated payments for 2020, either by check/mail or online in the IRS website? I have taxes withheld from salaries and pension during the year, and now I realize the taxes withheld may not be enough to cover the actual taxes owed (due to dividends and capital gain from my wife's new investment and retirement accounts; we file MFJ), and want to make additional payments to cover the differences so as not to incur any interests and penalties.
My 2020 taxes withheld for both federal and state are a little more than the actual taxes for 2019. The federal and state instructions appear to say that there would not be interest and penalty if the amounts that I have withheld are more than the actual taxes in the previous year (2019). But I expect that we would owe several thousand dollars more than I have withheld this year because my wife inherited her mother's investment accounts, and there are dividends and substantial capital gains (brokerage firm sells stocks and buys new ones regularly during the year, therefore incurring capital gains even if my wife does not receive the funds since they are re-invested in buying new stocks and funds). I assume that there won't be interest an penalty since the taxes withheld so far are more than actual taxes owed and paid in 2019. But I don't want to take any chances.
Thank you.
