IRS form walk-through
Form 433-D: The Agreement Itself, Not a Financial Statement
Form 433-D, Installment Agreement (Rev. 7-2024), is the single most misunderstood form in the 433 family, because it is not a Collection Information Statement at all. The 433-F, 433-A and 433-B are financial disclosures that help the IRS decide what you can pay. The 433-D is the agreement document that records the payment terms once a plan is approved, and it is where you authorize direct debit from your bank account.

How the four forms fit together
Form 9465 or the online application: the request for a monthly payment plan.
Form 433-F, or the longer 433-A, or 433-B for a business: the financial statement, required only when the balance or the proposal falls outside the streamlined lane.
Form 433-D: the resulting agreement, listing the monthly amount, the due date, and the bank authorization for direct debit.
Form 2159: the payroll deduction alternative, where your employer sends the payment instead of your bank.

What the direct debit authorization commits you to
The 433-D carries your bank routing and account numbers and authorizes the IRS to pull the agreed amount each month. That is usually in your favor, since direct debit agreements carry the lowest setup fee and remove the risk of forgetting a payment, and they are required for some balance ranges to stay streamlined. The tradeoff is that the money leaves on schedule whether or not the account is ready for it, and a returned payment can put the agreement into default.
433-D questions
What is the difference between Form 433-D and Form 433-F?
They serve opposite purposes despite the similar numbers. Form 433-F is a Collection Information Statement, a financial disclosure the IRS uses to decide what you can afford to pay. Form 433-D is the installment agreement document itself, recording the approved monthly payment and authorizing direct debit from your bank account.
Do I need to file Form 433-D to get a payment plan?
No. You request a plan through the IRS Online Payment Agreement application or Form 9465. The 433-D generally comes later, once terms are established, as the document that memorializes the agreement and sets up direct debit.
Is Form 433-D the same as Form 9465?
No. Form 9465 is the request for an installment agreement. Form 433-D is the agreement that results from it. One asks, the other confirms.
What happens if I miss a payment on a 433-D agreement?
A missed or returned payment can put the agreement into default, which allows the IRS to resume enforced collection. Because the 433-D is a direct debit arrangement, the more common failure is an account without sufficient funds on the scheduled date rather than a forgotten payment, so keep the debit date and your pay cycle aligned.
