So the IRS method kicks off...
It is generally not recommended to give the IRS more then absolutely necessary.. interest or not.. and they are the last place you would want to take advantage off imho. They have unlimited time and resources if they want to take a "deep dive" into your business. An IRS FR is expensive and risky.
I wouldnt go anywhere near this. (Though relying on IRS interest payments can be used as part of a *tax strategy* in unique circumstances when there is doubt etc.)
