Part I sets up your monthly payment plan. Part II is only needed in certain situations (you defaulted on a plan in the last 12 months, you owe between $25,000 and $50,000, or your proposed payment is below the line-10 amount).
Fields marked * are required.
For most individuals this is Form 1040.
Direct debit is the easiest way to make your payments on time, and it lowers the IRS setup fee.
Complete this part only if: you defaulted on an installment agreement in the last 12 months; the amount you owe is more than $25,000 but not more than $50,000; or the amount on line 11a (or 11b) is less than line 10.
