It is usually accompanied by Form 433-F or 433-D. If the request for a instalment payment contract is accepted, an applicant is notified of the terms of the new contract. The notice shall also indicate whether or not an applicant is eligible for the reduced fee. Also be aware that no matter what the IRS decides, you may still have to pay the fine if you don`t pay taxes on time. When the agreement is signed, the applicant agrees to make monthly payments instead of paying the full amount of debt at a time. A person who is unable to pay the full amount of the debt (as set out in their tax return) can request a monthly plan using Form 9465. The maximum duration of an optimized agreement made available by the IRS for this type of case is 72 months. It takes about 30 days for the IRS to respond to this request. This form consists of two parts. Each part indicates certain information about the nature of your debt.
