Called the IRS. No Payment Received. link to this post
My IRS check hasn't cleared. Odd. My state one did already. So I called them, and they couldn't find my payment, but they did notate my account so that they know I sent payment. She said to wait until the end of this month, and then call back to check again. Errr, why hasn't it cleared? Because I forgot to put my SSN on my check! I can't believe I didn't do that. The state cashed my check already though...and they didn't have my SSN. Come on IRS! Just because there are 250+ million people compared to my tiny state. You can match my address and name up, there are no excuses! Hah. Anyway, in case you're having the same problem:
IRS FAQ document Keyword: Payment Voucher (1040-ES) 1.1 IRS Procedures: General Procedural Questions I'm concerned because my check payment to the IRS has not been cashed yet. What should I do? You can call (800) 829-1040 and ask an IRS representative if the payment has been credited to your account. If it has not and the check has not cleared your financial institution, you may choose to place a stop-payment on the original check and send another payment.
