Can I pay taxes using bill pay from my on-line checking account?
I wouldn't do this. There is a chance that your check could get lost/misdirected/misapplied, etc.  Then you would need to deal with the huge bureaucracy to try to get it fixed while interest and penalties pile up.   What you can do is have the IRS withdraw the money themselves by providing the rounting number and account number of your bank.  This should work whether is it a traditional brick and mortar bank or an online bank.
