Here is a word from the Goodfellas of the IRS
For unemployed workers who filed Form 1127-A and qualified to get an extension to pay their 2011 federal income tax, Oct. 15 is also the last day to pay what they owe, including interest at the rate of 3 percent per year, compounded daily. Doing so will avoid the late-payment penalty, normally 0.5 percent per month.
Taxpayers can e-pay what they owe, either online or by phone, through the Electronic Federal Tax Payment System, by electronic funds withdrawal or with a credit or debit card. There is no IRS fee for any of these services, but for debit and credit card payments only, the private-sector card processors do charge a convenience fee. For those who itemize their deductions, these fees can be claimed on Schedule A Line 23. Those who choose to pay by check or money order should make the payment out to the “United States Treasury.”
Taxpayers with extensions should file their returns by Oct. 15, even if they can’t pay the full amount due. Doing so will avoid the late-filing penalty, normally five percent per month, that would otherwise apply to any unpaid balance after Oct. 15. However, interest and late-payment penalties will continue to accrue.
You have no excuses about not sending the payments. Pay your dear old Uncle Sam!
