  1. Are the taxes due that those dates, or can hey be post marked by that due date?

    • I came here to ask the same thing. I used to work in accounting and I prepare my own taxes. It was always the postmarked date, not the date they received it. Now that most people file and pay electronically, they have to pay no later than the due date. Up until now, I have been paying federal and state, tax returns and estimated, with paper forms and checks and mailing them on or close to the due date and getting a receipt from the post office.

      • From the IRS website: “If you mail your estimated tax payment and the date of the U.S. postmark is on or before the due date, the IRS will generally consider the payment to be on time. If you use IRS Direct Pay, you can make payments up to 8 p.m. Eastern time on the due date. If you use a credit or a debit card, you can make payments up to midnight on the due date.”

  2. Multi Member LLC is due March 15th. You should add that.
