How to set up an IRS installment payment agreement

IRS Procedure, Penalties & Notices 2 sources 2026-07-16

Question: How do you set up an IRS installment agreement?

Quick answer: If you can't pay your full federal tax bill, you can request a monthly payment plan (installment agreement) online through the IRS's Online Payment Agreement (OPA) system, or by mailing Form 9465. Approval isn't automatic — interest, and possibly a late-payment penalty, will still apply to the unpaid balance.

How it works

  • Eligibility/threshold for online setup: Taxpayers who can't pay the amount they owe for Form 1040 series returns and owe $50,000 or less in combined taxes, interest and penalties may use the Online Payment Agreement (OPA) application to request a payment plan (installment agreement). OPA will result in immediate notification of whether the payment plan is approved.

  • By mail: Alternatively, they can submit Form 9465, Installment Agreement Request, to the IRS by mail. The Provider can transmit Form 9465 electronically (if supported by software) with the taxpayer's electronic return data, or the form may be submitted later by mail. Keep in mind it may take 30 days or more for a response to Form 9465, regardless of how it is submitted.

  • Power of attorney: Authorized representatives with a power of attorney may use OPA on the taxpayer's behalf.

  • Fees: If the installment agreement is accepted, the IRS charges a user fee, which may be waived or reimbursed for low-income taxpayers. Taxpayers who apply through OPA are charged a lower user fee, and an even lower user fee if they use the direct debit payment option.

  • Interest and penalties still apply: If you can't pay the full amount due with your return, you can ask to make monthly installment payments for the full or a partial amount. However, you will be charged interest and may be charged a late payment penalty on the tax not paid by the date your return is due, even if your request to pay in installments is granted. If your request is granted, you must also pay a fee. To minimize costs, pay as much of the tax as possible with your return, but before requesting an installment agreement, you should consider other less costly alternatives, such as a bank loan or credit card payment.

  • How to apply: To apply for an installment agreement online, go to IRS.gov/OPA. You can also use Form 9465.

  • Making payments once approved: In addition to paying by check or money order, you can use a credit or debit card or direct payment from your bank account to make installment agreement payments.

What it depends on:

  • Total amount owed (the $50,000 combined-liability threshold applies to the streamlined online setup for individual returns)
  • Whether you want to apply online (faster answer) or by mail (slower)
  • Whether you choose direct debit (lower fee) vs. other payment methods
  • Your ability to pay a lump sum now to reduce ongoing interest/penalties

Since installment agreement fees, interest calculations, and eligibility can vary by individual circumstances (including whether you owe more than $50,000 or have other unresolved filings), it's worth a quick conversation with a CPA to make sure you choose the most cost-effective option for your situation.
