Yes, it was easy. I didn't even have to talk to anyone. Go to their website:
www.irs.gov and search for installment agreement. You can complete it on-line and arrange for payments. I used to have it taken out of my checking account, then I switched to billing, although I pay it on-line. Just don't be late with your payment and don't end up owing taxes for 2009 because it will invalidate your installament agreement.
