I'll have to pay taxes for the 2018 year, for how many months can I divide it?

Below $10,000. You have 3 years to pay. Divide your balance by 36,send that amount and request a payment plan in writing.

Good luck trying to get though to them. Just try to pay it in full if you can. I tryed get some one on phone for three weeks and dud not get to speak to anyone to see what I could of done so I just pay it in full.
