I then returned home and proceeded to call the IRS 800 number to make the payment over the Phone on a Credit Card, however the 800 number was closed and there was no menu on the phone that allowed for an automatic payment by credit card. I had no other option but to mail in the payment. So I mailed the money order in the amount of $900 to the California IRS office and got a certified receipt to prove payment and the date the payment was mailed. I hope there is enough staff there and a place that the payment will be received. It looks like it is not known when the government shutdown will end. I need to know if the IRS received the payment, and when it will be processed to my account as paid? I had the letter stamped to prove that it was mailed on time and should be received by the deadline due date of October 8th. I should not be held responsible for the Government Shutdown, as I knew nonthing about the shutdown on October 1, 2013 until after I had made arrangements for payment. I now owe the IRS a $200 balance when they credit that payment, and I told them I would pay that in November. I don't feel I should have to pay any additional interest or late charges under the circumstances. There money should be at the office by the due date.
