The Forms That Run IRS Collections
Almost every resolution path through IRS collections runs on a handful of forms: the payment plan request, the financial statement behind it, the settlement application, and the hearing request that can stop a levy. The numbering is genuinely confusing, and the 433 family is the worst of it, because 433-D is not a financial statement at all. Each walk-through below covers the current revision, from the official forms and instructions, including the thresholds, fees, and deadline mechanics the form itself buries in fine print.

Full walk-through →What is the difference between Form 433-A, 433-D, and 433-F?
These three get mixed up constantly, and the trap is that one of them is not a financial statement at all.
- Form 433-F is the short Collection Information Statement, the one the Automated Collection System uses for most payment plans over the streamlined threshold and for hardship requests.
- Form 433-A is the long version of the same disclosure, several pages of extra asset and business detail, and it generally signals that a Revenue Officer is assigned to the case.
- Form 433-D is not a financial statement. It is the installment agreement itself, the document recording the approved payment and authorizing direct debit.
- Form 433-A (OIC) is a fourth thing again: the worksheet inside the offer booklet that calculates an offer amount rather than a monthly payment.
Which form fits your situation
Owe money and want monthly payments: most people under $50,000 skip the paperwork entirely and use the IRS Online Payment Agreement, with Form 9465 as the paper route, and Form 433-D arriving afterward to record the agreement. Larger balances and hardship claims bring Form 433-F, or the longer Form 433-A when a Revenue Officer is involved. Settling for less than you owe is Form 656 and its booklet, priced by the 433-A (OIC) worksheet, unless you are disputing that you owe the tax at all, which is Form 656-L and carries no fee. And when a final levy notice or lien filing arrives, Form 12153 is the appeal that pauses enforcement while the case is heard.
