Would anyone know where the IRS might be hiding their downloadable on-line form 1040-ES for 2018 estimated tax payments for individuals via voucher and check? (The voucher to be mailed with check was a detachable part of the form in years past.) As of 4-Mar-2018, it appears that the official IRS website only has last year's (2017) 1040-ES form.
My tax preparation professional (H&R) provided pre-printed 1040-ES vouchers for quarterly 2018 estimated tax payments, but they have "Unapproved Form, Do Not File" boldly printed on top of the form. So I am reluctant to send those. Also, there are no boxes for critical identification info such as social security number on these H&R-provided 2018 vouchers, which seems strange and prone to not having one's payments recorded accurately.
Second related question: I'm curious if DA readers who pay estimated Federal taxes tend to elect to pay one single estimated tax amount for the entire year in the first quarter's payment, or if 4 quarterly payments throughout the calendar year are more popular?
Thanks.
