<prompt> Human: in 2016 I worked 1099 for a startup firm for 3 months. They paid me 15k and didnt withold any taxes. When I filed my 2016 taxes I forgot to enter the wages received, the company still reported the wages to the IRS so they sent me a proposed changes form to my 1040.They say I owe 6103 in back taxes, 1221 in Substantial Tax understatement penalty, and 349 in interest. What do I do? I have no problem paying the IRS but can they put me on a payment plan or something? I dont want to just send them 7600 in 1 lump some as that would take most of my savings out right now.Do I need to hire someone? Can I review my 1040 and find more deductions or something? Im just confused at where to go and I have until 530 to return a letter to them.  <response>: Yes, call them up and get on a payment plan.
