IRS Installment Agreement Fax Number — Set Up Your Payment Plan

If you can't pay your tax bill in full, the IRS lets you propose a monthly payment plan by faxing Form 9465 to 855-887-7734. Depending on your situation you may also send Form 433-D once an agreement is set up, or a Form 433-F collection information statement if the IRS wants detail on your finances. Faxing the request is among the quicker ways to get it into the collection queue, and a confirmation receipt documents exactly when you submitted it.

What You Can Fax to IRS - Installment Agreements

  • Form 9465 (Installment Agreement Request)
  • Form 433-D (Installment Agreement)
  • Form 433-F (Collection Information Statement)
  • Financial documentation supporting your payment plan
  • Correspondence responding to IRS installment agreement letters
Tip: On Form 9465, list your full name, SSN, and every tax year the agreement is meant to cover, then propose a specific monthly amount rather than leaving it open. If the IRS already sent you an installment agreement letter, fax your response and any supporting financial documents to 855-887-7734 together. Keep making whatever payments you can while the request is pending — doing so reduces added interest and shows good faith if the plan needs negotiation.
