Federal withholding
I received a refund of $2032 in 2019 so an overpayment as I owed $2812 and paid $4863 in withholdings. So I adjusted my withholdings and $1495 was taken out for 2020. I just did my taxes and I owe $2780 after my deductions. So I did the 2021 w4 estimator on the IRS site and it says to withhold $270 per pay check (now 24 left for 2021) based on
Expected tax withholding$1,932*
Anticipated tax obligation$6,454**
Estimated under payment$4,522
