IRS Form 433-D: What the Installment Agreement Means

What is IRS Form 433-D used for?

IRS Form 433-D records the terms of an installment agreement for federal tax debt. It identifies the covered liabilities, initial payment, monthly amount, payment date, later payment changes, and optional direct debit details. The signed form expresses agreement to those terms if the IRS approves the arrangement.

The form starts with the taxpayer name, address, identification numbers, and telephone numbers. It then identifies each kind of tax by form number, the tax periods covered, and the total amount owed as of a stated date. Those details tie the agreement to particular liabilities rather than every possible federal tax balance.

The payment terms can include an amount paid when the agreement begins, a recurring monthly amount, and the same monthly payment day from the first through the twenty-eighth. A separate row can schedule an increase or decrease on a future date. That row lets the written agreement reflect a planned change instead of relying on an informal expectation.

The direct debit area authorizes the United States Treasury and its financial agent to initiate monthly electronic withdrawals from the listed account. It is optional on the face of the form. A person who cannot make debit payments can use the self-identifier box, while someone who can use debit but chooses another method leaves that box unchecked.

Does signing Form 433-D mean the plan is approved?

No. Form 433-D says the signer agrees to its terms if the Internal Revenue Service approves the agreement. The form also says some agreements require managerial approval and that the IRS will provide notice of approval or nonapproval. A completed signature is therefore not the same as confirmed acceptance.

The distinction appears twice on the form. Near the signature line, the taxpayer initials and signs to accept the terms if approved. In the printed terms, the IRS says an agreement may require managerial approval and that it will notify the taxpayer when the agreement is approved or not approved. The IRS copy also contains an approval signature block for agency use.

Until approval is confirmed, a submitted proposal and an established agreement are different account states. The IRS payment plan guidance explains that an installment agreement request can remain pending while it is reviewed, established, withdrawn, or rejected. That pending period has collection rules of its own, but it does not turn every proposed payment term into an accepted agreement.

Useful records include the completed form, delivery confirmation, any IRS acceptance letter, the first bank withdrawal or posted payment, and later account history. The IRS says an online account can display a current plan type, due date, and payment amount. Those records are more informative than assuming that a signed PDF settled the status.

A balance notice can continue to arrive while paperwork is moving through the system. The notice date, amount, tax periods, and payment posting deserve separate review. A new letter does not automatically prove rejection, but it also should not be ignored merely because Form 433-D was returned.

How is each section of Form 433-D completed?

Form 433-D moves from identity and contact information to covered tax debts, payment terms, optional future changes, direct debit details, signatures, and IRS use fields. Some entries may already be filled by an IRS employee. The taxpayer instructions call for reviewing every term before signing and returning Part 1.

The form instructions say to include a spouse's name and signature when the agreement covers a joint liability. A corporate officer or partner can enter a title. Identification numbers should match the liability shown, and the listed tax form and period should match the account records connected to the agreement.

The chosen monthly day must be the same each month and can fall from the first through the twenty-eighth. The IRS states that it must receive the payment by that date. For direct debit, the chosen day is when the withdrawal is scheduled from the financial account.

The routing number instructions limit the first two digits to 01 through 12 or 21 through 32. The form warns against relying on a deposit slip because it can show an internal routing number. An account number can contain up to 17 characters. Spaces and special symbols are omitted, while hyphens are included.

What is the difference between Forms 433-D, 9465, and 433-F?

Form 433-D records installment agreement terms, Form 9465 requests a monthly payment plan, and Form 433-F reports current finances when the IRS needs collection information. They can appear in the same collection matter, but each serves a different purpose. The IRS correspondence identifies which document and delivery route apply.

The current IRS page says many individuals can apply online for a long-term plan when the combined tax, penalties, and interest are $50,000 or less and all required returns are filed. Other cases can involve Form 9465, Form 433-H, Form 433-F, or Form 433-B. The route depends on account type and the information the IRS needs.

That is why Form 433-D should not be described as a universal first application. It can formalize terms after a telephone conversation, field contact, or other review. If the IRS needs proof that a proposed amount fits current finances, a Collection Information Statement and records can be requested separately.

The letters and forms can overlap without becoming interchangeable. A financial statement can support the proposed amount, Form 433-D can record the agreement, and a later CP523 can report a default issue. Keeping each document with its date and purpose reduces confusion about what has been requested and what has been accepted.

How does direct debit work on Form 433-D?

The direct debit section authorizes a monthly ACH withdrawal from the listed financial account on the agreed payment day. It asks for routing and account numbers and allows a voided check. The authorization continues until the IRS is notified to end it, subject to the timing rules printed on the form.

The form permits withdrawal from an account at a bank, mutual fund, brokerage firm, credit union, or another financial institution that allows the transaction. The instructions say to confirm that direct debit is available and to obtain the correct routing and account numbers from the institution.

For a scheduled transfer, the authorization language gives two timing routes. The financial institution can be contacted orally or in writing at least three business days before the next electronic funds transfer. Alternatively, the IRS can be contacted at least 14 business days before that transfer through the applicable telephone number on the form.

Stopping one electronic transfer is not listed as a revision of the agreement terms. The IRS online account guidance separately describes changes to payment amounts, payment dates, plan types, and direct debit bank information. A payment method problem and an approved plan change are therefore separate administrative events.

The payment checklist also anticipates an occasional missed withdrawal. It says to allow one additional month before contacting the IRS when a scheduled withdrawal does not occur. Because the monthly obligation remains part of the agreement, payment records and account history can show whether the amount later posted or remained unpaid.

What fees, interest, and penalties apply to Form 433-D?

An approved installment agreement can carry a setup fee, and interest plus applicable penalties continue until the balance is paid. Current fees depend on the application channel, payment method, and low-income status. The IRS payment plan page should be checked because online fees can be lower than phone, mail, or in-person fees.

These are setup fees, not payments against the tax balance. The IRS page updated March 3, 2026 also shows separate revision or reinstatement charges in some situations. A change made online generally costs less than a change made by phone, mail, or in person, and qualifying low-income taxpayers receive different treatment.

The first page of Form 433-D states that the listed federal taxes are paid together with penalties and interest provided by law. The current IRS payment plan page likewise says accrued penalties and interest continue until full payment. A monthly payment therefore does not freeze the account at the balance printed when the form was signed.

The form terms also say federal refunds and overpayments can be applied to the amount owed until the debt is fully paid or the collection period expires. A refund offset does not replace the next monthly payment unless the IRS changes the agreement or confirms that the liability is fully paid.

The fee table printed on Form 433-D reflects the phone, mail, or in-person rates of $107 for direct debit and $178 for a non-direct debit agreement. The live IRS page supplies the lower online rates. Comparing both sources prevents an online fee from being mistaken for the amount printed on a mailed agreement.

Where is Form 433-D sent?

Part 1 of Form 433-D goes to the address on the IRS letter that came with the form or to the address in the form's For assistance box. There is no single universal mailing address printed for every Form 433-D. Part 2 is retained as the taxpayer copy.

The return instruction appears on the back of the official form. It says to send Part 1 to the address on the accompanying letter or the city, state, and ZIP Code entered in the For assistance box on the front. This makes the form itself and its linked correspondence more specific than a generic address found elsewhere online.

The general IRS non-return forms address page does not publish one Form 433-D address. Its payment row routes other collection payment forms to additional instructions. Form 433-D instead carries its own direction back to the accompanying letter or completed assistance box.

Part 1 and Part 2 contain the same main agreement fields. Part 1 is marked IRS Copy. Part 2 is marked Taxpayer's Copy and includes the full instructions on the reverse. Keeping Part 2 preserves the tax periods, payment terms, direct debit information, signatures, and any IRS entries that were present when the agreement was prepared.

A delivery record can identify the date, address or fax number used, pages sent, and tracking or confirmation number. Sensitive identifiers and banking information should not appear in an ordinary email unless the IRS has provided a secure method for that contact. The route on the official letter remains the primary reference.

What does the installment agreement require after approval?

After approval, the agreement requires payments by the stated monthly date, timely filing of federal returns, timely payment of new federal taxes, and updated financial information when requested. It remains in effect until the covered liabilities are paid, the collection period expires, or the IRS terminates the agreement under its terms.

The reverse side of Form 433-D is part of the agreement. It says each payment must reach the IRS by the monthly due date. It also says that doubling one payment and skipping the next is not the ordinary schedule unless the IRS is contacted first. A reminder notice is not required before the scheduled payment remains due.

Compliance extends beyond the old balance. All required federal tax returns remain due, and new federal taxes must be paid on time. The IRS can also request updated financial information because the agreement is based on current financial condition. A significant change in ability to pay can lead the agency to modify or terminate the plan.

For check or money order payments, the printed checklist says to make the payment payable to United States Treasury, add the SSN or EIN, and identify the type of tax, tax period, and Installment Agreement. It also says to include a reminder notice when one was received and use the address shown on the form.

The agreement allows the IRS to apply payments in the government's best interests. The form says payments generally go to the oldest collection statute, which is normally the oldest tax year or period. That order matters when several periods appear on the same agreement and the displayed balances change at different rates.

The IRS can still file a Notice of Federal Tax Lien while an agreement is in effect. The IRS use section of Form 433-D records whether a notice has already been filed, will be filed, or may be filed after default. An installment agreement and a public lien filing are related collection events, not mutually exclusive outcomes.

What can cause a Form 433-D agreement to default?

The IRS can terminate an installment agreement for missed monthly payments, a new federal tax debt that is not paid when due, failure to provide requested financial information, or jeopardy to collection. The agency generally sends notice before termination, and the specific letter explains the proposed action and response period.

The agreement terms list three ordinary triggers together: monthly payments are not made as agreed, another federal tax debt is not paid when due, or requested financial information is not provided. The terms also permit termination at any time if the IRS finds that collection of the tax is in jeopardy.

A CP523 notice concerns default and proposed termination of an installment agreement. It is different from the earlier balance sequence. A CP14 balance notice, CP501 reminder, and CP504 collection notice each describe other stages or events in an unpaid account.

The current IRS payment plan page says an online account can change a monthly amount, payment date, plan type, and direct debit bank information. It can also be used for reinstatement after default in supported cases. If a proposed amount does not meet account requirements, the system can direct the person to a financial statement and further submission instructions.

If an agreement is terminated, Form 433-D says the IRS may collect the amount through levy on income, bank accounts, or other assets, or through property seizure, subject to applicable procedures. Reinstatement can carry a fee. The balance can also continue changing because interest and applicable penalties do not stop during the plan.
