IRS Form 433-D documents an approved installment agreement and, when applicable, authorizes recurring direct-debit payments from a bank account.
Taxpayers normally use Form 433-D after discussing payment terms with the IRS, not as a substitute for an online installment-agreement application. The form identifies covered tax periods, balances, payment date and amount, user fee treatment, and bank details for a direct debit.

What Is IRS Form 433-D?
An installment agreement permits monthly payments but does not remove the tax, penalties, or interest. The federal tax collection process and lien rules may continue according to law and the agreement terms.
The form can be signed by the taxpayer and an authorized IRS official. A payroll-deduction agreement generally uses Form 2159, while many qualifying individuals can apply or revise a plan through an IRS Online Account.
Who Should Use IRS Form 433-D?
- A taxpayer whom the IRS instructs to sign Form 433-D after negotiated terms are established.
- An individual or business setting up a direct-debit installment agreement.
- Joint taxpayers who both need to sign the agreement.
- A representative with valid authority to enter the agreement when permitted.
- Not a taxpayer merely exploring options; use the IRS online application or the contact method in the notice first.
How to Use or Complete IRS Form 433-D
- Confirm the tax form, tax periods, assessed balances, proposed payment, and payment date with the IRS.
- Choose a monthly amount that meets the accepted terms and can be sustained alongside current taxes.
- For direct debit, enter the correct routing number, account number, account type, and financial-institution information.
- Review user-fee, modification, and default provisions printed on the current form.
- Have all required taxpayers sign and return the form through the secure method directed by the IRS.
- Verify that the agreement was approved and that the first automatic payment posts correctly.
Direct Debit Information
Use the routing and account numbers from the bank, not merely the numbers on a deposit slip. Confirm whether the account permits ACH debits and whether both spouses’ authorization is needed for a joint account.
A direct-debit authorization generally continues until the liability is paid, the agreement is changed, or authorization is revoked under the agreement’s terms. Revoking the debit does not cancel the tax debt and can default the agreement if another payment method is not approved.
Terms That Can Default an Agreement
- Missing or underpaying a monthly installment.
- Failing to file future required returns on time.
- Failing to pay current tax, estimated payments, or federal tax deposits.
- Providing materially inaccurate financial information.
- Failing to supply updated financial information when a review is required.
- Allowing a direct debit to fail without promptly arranging a cure.
Penalties, Interest, Refunds, and Liens
Penalties and interest generally accrue until the balance is fully paid. The IRS usually applies future federal refunds to the debt, and those offsets normally do not replace the scheduled monthly payment.
A notice of federal tax lien may be filed depending on the balance and agreement type. Full payment is usually the least expensive option; paying more than the minimum reduces future accruals.
Changing or Ending Form 433-D Payments
Contact the IRS before a payment will be missed. Qualifying individuals may be able to revise a direct-debit amount or date online; other agreements require phone or written contact and may incur a restructuring fee.
Do not close the bank account or stop payment as a way to renegotiate. Secure approval of the replacement arrangement and retain its confirmation.
Before You File or Submit
- Use the current official version. Tax forms, addresses, thresholds, and electronic filing procedures can change. Download the form or instructions from the issuing agency immediately before use.
- Match names and taxpayer identification numbers. Confirm that legal names, SSNs, ITINs, EINs, plan numbers, and tax periods agree with the related return and agency records.
- Gather supporting records first. Keep calculations, statements, notices, authorizations, appraisals, receipts, and other documents that support every entry.
- Check the deadline and delivery method. An extension to file does not necessarily extend the time to pay. Private carriers also may require a different street address than USPS.
- Sign where required. An unsigned paper form, missing consent, or incomplete electronic authentication can delay or invalidate a submission.
- Keep a complete copy. Retain the filed form, attachments, confirmation number, proof of mailing, fax confirmation, and payment record.
Common Mistakes to Avoid
- Sending Form 433-D without first obtaining or proposing terms through the correct IRS channel.
- Transposing bank routing and account numbers.
- Choosing a monthly amount that leaves no room for new estimated or payroll taxes.
- Assuming a future refund replaces the normal monthly payment.
- Stopping the bank debit without changing the agreement.
- Failing to verify that the IRS received and approved the signed form.
What Happens After Submission?
Once approved, payments begin on the agreed day and are applied to the covered liabilities under IRS payment-order rules. Monitor both the bank account and IRS transcripts.
If the IRS proposes termination or default, respond by the deadline in the notice. A Collection Appeals Program or other review may be available depending on the action.
Processing time is not the same as a legal deadline. Do not submit a duplicate merely because an acknowledgement or response has not arrived. First check the relevant online status tool, confirmation record, or official contact channel. If the agency requests more information, respond by the date and method stated in the notice.
Records to Keep
Keep a copy of the completed submission and all documents used to prepare it. Your file should also contain the tax-year or period involved, the date submitted, the delivery method, any confirmation or tracking number, and notes about later agency correspondence. Retention periods depend on the form and issue, so follow the specific instructions and keep records longer when they may remain material to an audit, refund claim, basis calculation, collection case, election, or amended return.
Frequently Asked Questions
Can I download Form 433-D and approve my own payment plan?
No. The agreement requires IRS acceptance. Many taxpayers should first use the Online Payment Agreement application or contact the number on their notice.
Does an installment agreement stop interest?
No. Interest and applicable penalties generally continue until the balance is paid.
Can I pay extra?
Yes. Additional voluntary payments generally reduce the balance and future accruals, but the required monthly payment remains due unless the agreement is changed.
What if my bank account changes?
Update the direct-debit authorization through the permitted IRS procedure before the next draft. Allow processing time and monitor the old account until the change is confirmed.
Official Resources
Bottom line: Use Form 433-D to document terms accepted by the IRS, verify every bank digit, budget for current taxes as well as the installment, and contact the IRS before a payment fails.
