Form 433-D Installment Agreement Checklist
Overview and Purpose
Form 433-D is the IRS Installment Agreement form used by taxpayers to establish a structured payment plan for taxes owed over time. This form helps taxpayers make monthly payments to the IRS that they can afford, thereby preventing harsh actions such as seizing property or garnishing wages. The form serves as a formal agreement outlining specific payment terms, conditions, and obligations that both parties must follow throughout the installment plan duration.
Ten-Step Workflow for Completing Form 433-D
Step 1: Provide Complete Taxpayer Information
Enter your full legal name and current mailing address. Include your spouse’s name if the tax liability is joint. Provide both home and work, cell, or business telephone numbers with area codes to ensure the IRS can contact you regarding your agreement.
Step 2: Enter Taxpayer Identification Numbers
Accurately enter your Social Security Number, Individual Taxpayer Identification Number, or
Employer Identification Number, depending on whether the liability is individual or business-related. If filing jointly, include your spouse’s identification number. Double-check for accuracy to avoid processing delays.
Step 3: Specify Tax Types and Periods
List the specific tax types using appropriate form numbers, such as Form 1040 for individual income tax, Form 941 for employment taxes, or Form 1120 for corporate income tax. Enter the tax periods involved, typically shown as tax years or quarters. Include all periods covered under this installment agreement.
Step 4: Declare Total Amount Owed
Enter the total amount of tax liability owed as of the submission date, including all taxes, penalties, and interest. This amount should match IRS notices if you have received prior notification. Subtract any payments made since your last notice to arrive at the current balance.
Step 5: Propose Payment Terms
Indicate the amount you can pay immediately as a partial payment, if any. Enter the amount you propose to pay each month and specify the payment day between the 1st and the 28th. Choose a date that aligns with your income receipt to ensure funds are available. This payment date remains consistent throughout the agreement.
Step 6: Select and Authorize Payment Method
Choose your preferred payment method. You can pay by check or money order, or authorize direct debit for electronic withdrawal from your bank account. If you select direct debit, please complete the Direct Debit section with your bank's routing number and account number. Attach a voided check or carefully enter the numbers to ensure accuracy. The routing number must begin with 01 through 12 or 21 through 32.
Step 7: Review Agreement Terms Thoroughly
Carefully read all terms and conditions. Pay attention to your obligation to make timely monthly payments, requirements to file future returns and pay new taxes on time, the IRS’s right to apply tax refunds to your balance, consequences of default, circumstances for agreement modification or termination, and the IRS’s authority to file a Notice of Federal Tax Lien if not already filed.
Step 8: Initial and Sign the Form
Place your initials where indicated to acknowledge that you have reviewed and understand the terms. Sign and date the form in the designated signature area. If the tax liability is joint, your spouse must also sign. Corporate officers or partners must include their title. Ensure signatures are original handwritten signatures when submitting by mail or fax.
Step 9: Understand Submission Methods
If you received Form 433-D from the IRS, return Part 1 to the address specified in the accompanying letter or notice. In some cases, your correspondence may include a fax number permitting fax submission. Most taxpayers can apply online through the IRS Online Payment
Agreement application at IRS.gov, which eliminates the need to mail Form 433-D and provides immediate feedback on eligibility and approval.
For questions about submission, call the IRS at the phone numbers on your notice or the assistance numbers on Form 433-D.

Step 10: Retain Copies and Monitor Confirmation
Make complete copies of the filled-out form and any attachments for your records. Keep Part 2 as your taxpayer copy. After submission, allow time for the IRS to process your information. You will receive written notification regarding approval or non-approval. Once approved, begin making payments according to the established schedule.
If you are unable to make a scheduled payment, please contact the IRS immediately. Maintain timely filing and payment of all current-year obligations while the agreement is in effect.
Essential Rules and Requirements
Signatures must be provided by the taxpayer or authorized representative. When submitting by mail or fax, use handwritten signatures. The IRS accepts electronic authentication when applying online through IRS.gov, which eliminates the need for wet signatures on Form 433-D.
Each signature certifies the accuracy and completeness of the information provided.
All information must be truthful, accurate, and complete. False details or withholding information could invalidate the agreement and result in penalties. The IRS relies on your information to determine appropriate payment terms.
Only authorized representatives are permitted to sign on behalf of taxpayers. Representatives must have proper authorization through Form 2848, Power of Attorney, and Declaration of
Representative. For business entities, corporate officers or partners with binding authority must sign. In joint liability situations, both spouses must sign unless only one spouse is legally responsible.
Supporting financial documentation may be required to verify your ability to pay. This can include bank statements, pay stubs, income verification, profit and loss statements for self-employed individuals, and documentation of monthly expenses. Provide complete and accurate documentation when requested.
Payments must be made via IRS-accepted methods: checks or money orders to the United
States Treasury, direct debit, online payments, credit/debit card payments through authorized processors, or the Electronic Federal Tax Payment System. When using direct debit, provide accurate routing and account numbers and complete the authorization section.
Submit the form according to the instructions in your IRS correspondence. If you received Form
433-D from the IRS, mail Part 1 to the address in the accompanying letter. Some cases permit fax submission if a fax number is included. Do not submit sensitive information via unsecured email. The preferred method for most taxpayers is the online application at IRS.gov, which provides secure electronic submission.
Understand user fees associated with installment agreements. Fees vary depending on payment method and income level. Non-direct debit agreements have higher fees than direct debit agreements. Direct debit may completely waive fees for low-income taxpayers who meet the federal poverty guideline thresholds. Online applications often have lower fees than paper applications. Complete Form 13844 to request a waiver based on low-income status.
Monitor your agreement status and maintain all payment obligations. Keep records of all payments, including the date, amount, and confirmation numbers. If you receive reminder notices, use the payment coupon included. Ensure that payments are made on time, even if you do not receive a reminder notice. Write your taxpayer identification number, tax type, tax period, and “Installment Agreement” on all checks or money orders.
Your installment agreement can be terminated if you fail to make monthly payments, fail to file required returns or pay current taxes, provide false information, or fail to provide requested financial information. If terminated, the IRS may take immediate collection action, including levying bank accounts, garnishing wages, or seizing property. To reinstate a defaulted agreement, you must pay a reinstatement fee and establish new payment terms. If your financial situation changes significantly, contact the IRS to request a modification rather than defaulting.
The IRS applies payments to the oldest tax period first to maximize collection before statutes of limitation expire. Tax refunds and overpayments are automatically applied to your outstanding balance. The agreement remains in effect until your entire liability, including penalties and interest, is paid in full or the statutory collection period expires.
Understanding your rights and obligations is crucial for the successful completion of the payment plan and resolving your tax debt, while avoiding potential default situations that could result in more severe collection actions.
