Pigy-backing off of this question. I am a single-member LLC and I have an EIN. I enrolled in EFTPS to pay quarterly taxes under that EIN. My accountant told me to pay under form 1040-ES, but that form wasnt on the list. After talking to a customer service rep at EFTPS, they said that 1040-ES will only show up if you are registered under your SSN and that I must use 941 to pay under the EIN. Is this going to affect anything, or will everything be fine if I pay under 941, as a single-member LLC?
