I just filed my 2019 taxes. I owe a little over $1000 in Federal but will receive a State refund. After I filed, in the turbo tax PDF copies, I received an IRS 1040-ES, to submit 4 quarterly payments for estimated Fed Tax shortfall for 2020.
My question is, are these 1040-ES coupons now mandatory based on my 2019 filing? I'm not a contractor nor self employed but rather a Gov employee. Perhaps I can just lower my Witholding # for pay this year, and thereby increase Fed Tax deductions. In that case, would I still have to submit these 4 1040-ES vouchers?
