As of 2015, Form 9465, the Installment Agreement Request, is available online at IRS.gov, according to the Internal Revenue Service. Taxpayers can click on the Forms & Pubs link located at the top of the home page to access the form and instructions under the Featured Forms & Publications heading.
Individuals who owe federal income tax on Form 1040 may qualify to use Form 9465 to request a payment arrangement, advises the IRS. Taxpayers who are responsible for a trust fund recovery penalty or who owe employment tax on a business that is no longer open may also qualify to use Form 9465.
Taxpayers who have filed for bankruptcy or have an existing offer in compromise with the IRS should not complete Form 9465, notes the IRS. Instead, they can call 800-829-1040 for assistance.
