If I am currently on a payment plan with the IRS and in the agreement it states that your are not to owe any more taxes while in the payment agreement... what happens if I do owe for the current year. I am paying off 2004 taxes and now I owe for 2007... what is going to happen? It will default my agreement, will they set a new agreement or start levy action? It is still a payable amount. Thanks for any help!
