Demystifying IRS Settlement Options: Partial Pay Installment Agreement (PPIA) vs. Offer in Compromise (OIC)

Navigating the world of IRS tax settlements can feel overwhelming, especially when faced with complex rules and multiple options. As an Enrolled Agent, my mission is to make these topics approachable and actionable for everyone—whether you’re a taxpayer seeking relief or a fellow practitioner looking for clarity.

Why Settlement Choices Matter

No two tax debt situations are alike. That’s why understanding the nuances between different IRS settlement options is crucial. In this blog, I address two of the most commonly discussed solutions – the Partial Pay Installment Agreement (PPIA) and the Offer in Compromise (OIC). Each has its own strengths, limitations, and ideal scenarios.

Let’s break down the main features of each option:

Offer in Compromise (OIC)

  • Definition: An agreement between a taxpayer and the IRS that settles tax liabilities for less than the full amount owed.
  • Eligibility: Taxpayer generally won’t qualify if they can fully pay the liabilities through an installment agreement or other means.
  • Requirements: Must have filed all tax returns, received a bill for at least one tax debt included in the offer, made all required estimated tax payments for the current year, and (if a business owner) made all required federal tax deposits for the current and previous two quarters.
  • IRS Acceptance Criteria:
    • Doubt as to Liability: Genuine dispute about the existence or amount of the correct tax debt.
    • Doubt as to Collectibility: Taxpayer’s assets and income are less than the full amount of the tax liability.
    • Effective Tax Administration: No doubt the tax is owed and collectible, but payment in full would cause economic hardship or be unfair due to exceptional circumstances.

Approval Rate: The approval rate of an offer has been fluctuating over the years.  Historically, the acceptance rate has averaged around 36%.

Amount Offered: Must be equal to or greater than the reasonable collection potential (RCP), which includes the value of assets and anticipated future income minus basic living expenses.

Partial Payment Installment Agreement (PPIA)

  • Definition: An installment agreement where the taxpayer pays less than the full balance owed by the Collection Statute Expiration Date (CSED), which is generally 10 years from the date the tax was assessed.
  • Eligibility: For taxpayers who cannot afford to pay the full amount by the CSED.
  • Requirements: Must complete a Collection Information Statement (Form 433-F, 433-A, or 433-B) and provide supporting financial information.
  • IRS Actions: May issue a public notice of federal tax lien.
  • Review: Agreement is subject to review every two years; taxpayer may need to provide updated financial information, which could change the monthly payment amount.
  • CSED: IRS has 10 years to collect the tax, penalties, and interest. Multiple assessments can have different CSEDs.
  • Most Appealing Feature:  PPIA’s are traditionally easier to get approved by the IRS.

Making the Right Choice

Offer in Compromise (OIC)

  • Best if: You cannot pay your full tax debt and your assets/income are less than what you owe, or paying in full would cause economic hardship or be unfair due to exceptional circumstances.
  • Requirements: You must have filed all tax returns, received a bill for at least one tax debt, made all required estimated tax payments, and (if you’re a business owner) made all required federal tax deposits. The IRS usually only accepts an OIC if your offer is at least equal to your reasonable collection potential (RCP).

Partial Payment Installment Agreement

  • Best if: You can pay part of your tax debt over time, but not the full amount before the Collection Statute Expiration Date (CSED, generally 10 years from assessment). You’ll need to provide financial information, and your agreement will be reviewed every two years.

When Is a PPIA Not the Right Fit?

A Partial Pay Installment Agreement isn’t always the best solution. Here are a few situations where it may not work well:

  • Rising Income: If your income is expected to increase significantly in the near future, the IRS may reconsider your ability to pay.
  • Substantial Assets: Having unencumbered assets that could easily cover your tax debt may disqualify you from a PPIA.
  • Near the End of Collection Period: If you’re less than a year away from the end of the IRS collection statute, other options—like a short-term payment plan or Currently Not Collectible (CNC) status—might be more appropriate.

Conclusion

Choosing between a PPIA and an OIC isn’t just about eligibility—it’s about finding the solution that fits your financial reality and future outlook. The IRS looks at your assets, income, expenses, and the time left on the collection statute. That’s why working with a knowledgeable tax professional who can personalize your approach is so important.

If you’re unsure which path is best for you, consider seeking advice from a tax professional or tax resolution specialist who can guide you through the maze of IRS options. With the right guidance, you can turn confusion into confidence and take meaningful steps toward resolving your tax debt.
