What is IRS Form 433-D?

IRS Form 433-D is the Installment Agreement form. If you owe the IRS money and can't pay the full amount at once, this form lets you set up a monthly payment plan. It authorizes the IRS to collect payments — either through direct debit from your bank account or through regular monthly payments you initiate.

How to Submit Form 433-D to the IRS

1

Complete Form 433-D

Fill in your personal information, the amount you owe, and your proposed monthly payment amount. Include your bank routing and account numbers if you're authorizing direct debit payments.

2

Submit as directed by your IRS representative

Form 433-D is usually completed during a conversation with an IRS revenue officer. If they provide a fax number, use usfax.com to fax the form with delivery confirmation. Otherwise, follow their instructions for submission.

3

Save your confirmation

Keep your fax delivery confirmation or any receipt as proof you submitted your installment agreement request — this is important if any disputes arise about your submission date.

Common Mistakes to Avoid

  • Proposing a monthly payment amount that's too low for the IRS to accept — generally, you need to pay off the balance within 72 months.
  • Entering incorrect bank routing or account numbers for direct debit — double-check these before submitting to avoid payment failures.
  • Not including all required information — incomplete forms get rejected. Make sure every field is filled in before you submit.
