Form 433-D, Installment Agreement
Form 433-D is the agreement document itself: once the IRS approves a payment plan, this form locks in the terms and, usually, the direct debit authorization that funds it.

What is 433-D?
Where Form 9465 asks for a plan, Form 433-D executes one. It records the tax periods covered, the monthly amount, the payment date, and your banking details for direct debit, and it carries your signature agreeing to the terms and conditions printed on it, including the IRS’s right to terminate the agreement if payments are missed or new balances go unpaid.
The IRS typically sends it to you after approving an arrangement, often initiated by phone or through a revenue officer.
Who files 433-D?
- Taxpayers finalizing an installment agreement the IRS has approved
- People converting an existing plan to direct debit
- Anyone a revenue officer or IRS notice has asked to return a completed 433-D

Frequently asked questions
Is direct debit required?
Not for every agreement, but the IRS requires it for larger balances and it lowers fees and removes the risk of a forgotten payment defaulting the plan.
What voids the agreement?
Missing a payment, failing to file future returns on time, or leaving a new balance unpaid can all terminate it, after which the full amount is collectible at once.
