IRS Form 433-D – Installment Agreement – If you owe the IRS money and can’t pay your full tax balance immediately, an installment agreement (also called a payment plan) can provide relief by letting you pay over time in manageable monthly installments. IRS Form 433-D (Installment Agreement) is the key document the IRS uses to set up — and formalize — these agreements, especially when direct debit (automatic withdrawals from your bank account) is involved.
This comprehensive guide explains everything you need to know about Form 433-D based on official IRS sources (as of February 2026), including when to use it, how to complete it step-by-step, current fees, eligibility, benefits, and more. The latest revision is July 2024 (Rev. 7-2024).

What Is IRS Form 433-D?
Form 433-D is a one-page IRS form titled “Installment Agreement”. It establishes a formal agreement between you (the taxpayer) and the IRS to pay your federal tax debt — including accrued penalties and interest — in monthly installments until the balance is paid in full or the collection statute expires (typically 10 years from assessment).
- It is primarily used for Direct Debit Installment Agreements (DDIA), where payments are automatically withdrawn from your checking or savings account.
- The form can also support non-direct debit payments, but direct debit is strongly encouraged (and often required) for lower fees and higher approval chances.
- Important distinction: Form 433-D is not the initial request form. You typically use it to finalize or set up the specific payment terms after applying for an installment agreement (via the online tool, Form 9465, or phone). The IRS often mails it to you with instructions after preliminary approval.
Key fact (2026): Businesses owing more than $10,000 on a long-term plan generally must use direct debit, making Form 433-D essential in those cases.
Who Should Use Form 433-D?
Use Form 433-D if:
- You have been approved (or are finalizing) a long-term installment agreement and want (or are required) to pay via direct debit.
- The IRS requests it after you apply online, by phone, or with Form 9465.
- You are self-employed, a business owner, or an individual with a balance that requires a structured monthly plan.
- You need to revise an existing agreement or set up automatic payments.
It is not needed for:
- Short-term payment plans (paid in full within 180 days).
- Very simple online agreements under certain low-balance thresholds where everything is handled digitally.
Form 433-D vs. Form 9465: What’s the Difference?
| Form | Purpose | When to Use | Direct Debit? |
|---|---|---|---|
| Form 9465 | Initial request for installment agreement | To apply by mail/phone when you can’t pay in full | Optional |
| Form 433-D | Formalize the actual agreement and payment schedule | To set up or confirm monthly payments (especially DDIA) | Strongly recommended/required in many cases |
Many taxpayers start with the Online Payment Agreement tool or Form 9465, then receive Form 433-D to complete the direct debit setup.
IRS Installment Agreement Eligibility (2026)
You generally qualify for a long-term installment agreement if:
- You have filed all required tax returns.
- For individuals: Combined tax, penalties, and interest ≤ $50,000 (simple plans available up to this amount).
- For businesses: ≤ $25,000 (or higher with additional review).
- You agree to pay future taxes on time and meet all filing requirements.
Guaranteed Installment Agreements are available for individuals owing $10,000 or less (excluding penalties/interest) under specific conditions.
Online eligibility (preferred method):
- Individuals: Up to $50,000 for long-term plans.
- Businesses: Up to $25,000.
If your balance is higher or you can’t meet the minimum payment calculated by the IRS, you may need to provide a Collection Information Statement (Form 433-F, 433-H, or 433-B) and use Form 433-D for the final agreement.
