In a recent fiscal year, the IRS accepted only 38% of the Offers in Compromise it processed, per the official IRS Data Book. The biggest mistake candidates make on the EA exam is treating this topic like a simple calculation. The exam doesn't just test if you can compute an offer; it tests your judgment on whether an offer is viable in the first place, which is precisely where most candidates stumble.
An Offer in Compromise (OIC) is an IRS agreement resolving a taxpayer's liability for less than the full amount owed. For the EA exam, you must master the three mutually exclusive grounds for acceptance: Doubt as to Liability, Doubt as to Collectibility, and Effective Tax Administration, and be able to calculate the minimum offer.
Key facts
- Exam Part: Special Enrollment Examination (SEE) Part 3: Representation, Practices, and Procedures
- Key Forms: Form 656 (Offer in Compromise), Form 433-A (OIC) (for individuals), Form 433-B (OIC) (for businesses)
- Application Fee (2026): $205 (non-refundable, subject to change)
- Core Concept: Reasonable Collection Potential (RCP)
- Prerequisite: Taxpayer must be in full compliance (all required returns filed, current estimated tax payments made).
- Grounds for Acceptance: Doubt as to Liability, Doubt as to Collectibility, or Effective Tax Administration.
The IRS reports that in Fiscal Year 2023, it accepted 14,000 OICs out of 36,000 processed (IRS Data Book, Table 18).
What is an OIC and Why Is It So Tricky on the EA Exam?
An Offer in Compromise (OIC) is a formal proposal to the IRS to settle a client's tax debt for less than the amount billed. It is reserved for taxpayers in specific financial situations and is governed by strict standards, not open-ended negotiation. Before the IRS will even process an OIC, the taxpayer must be in current compliance—all required tax returns must be filed and all required estimated tax payments must be made.

On the SEE Part 3 exam, OIC questions test your diagnostic skills. The IRS wants to ensure you can protect your client's interests and the government's by making sound, evidence-based recommendations. Try VoraPrep's free EA practice questions to see how these judgment calls are framed.
The most common failure is focusing on the numbers before the reason. Candidates memorize the payment calculation but fail to identify the correct grounds for making the offer. The exam will present a scenario and expect you to diagnose the situation first. Is the liability itself questionable, or can the taxpayer simply not pay?
Choosing the wrong path leads directly to a distractor answer. Our adaptive learning engine at VoraPrep consistently identifies this diagnostic step as a weak point for new students. You must master the three fundamental reasons the IRS will consider an OIC before you calculate a single dollar.
What Are the Three Grounds for an OIC the Exam Will Test?
Your success on OIC questions hinges on correctly categorizing the client's problem into one of three mutually exclusive grounds. You must choose only one.
| Ground for Acceptance | When It Applies | Key Consideration |
|---|---|---|
| Doubt as to Liability | The taxpayer genuinely disputes the existence or amount of the tax debt itself. | This is not about inability to pay. The taxpayer must provide evidence that the assessed tax is incorrect per IRC rules. |
| Doubt as to Collectibility | The taxpayer agrees they owe the tax but lacks the assets and income to pay the full amount. | This is the most common type. It relies entirely on the Reasonable Collection Potential (RCP) calculation. |
| Effective Tax Administration (ETA) | The taxpayer can pay, but doing so would create an economic hardship or be unfair and inequitable. | This is a high bar. It's based on compelling circumstances, not just financial numbers. |
Doubt as to Collectibility and Reasonable Collection Potential (RCP)
This is the heart of most computational OIC exam questions. The IRS will only accept an offer on these grounds if the amount is equal to or greater than the taxpayer's Reasonable Collection Potential (RCP).
> 🧮 Formula: > Reasonable Collection Potential (RCP) = Net Realizable Equity in Assets + (Monthly Disposable Income x Future Income Multiplier)
The examiner will test your ability to apply this formula precisely. They will give you asset values, liabilities, income, and expenses. Your job is to parse the data, calculate the RCP, and determine the minimum acceptable offer.
OIC Payment Options and Key Deadlines
The taxpayer must choose one of two payment options. This choice dictates the initial payment required with the application and the multiplier used in the RCP formula.
- Lump-Sum Cash Offer: The offer is paid in 5 or fewer payments within 5 months of the OIC acceptance date.
- Initial Payment: The taxpayer must include a non-refundable payment of 20% of the total offer amount with the Form 656 application.
- RCP Multiplier: Use 12 months of future disposable income in the RCP calculation.
- Periodic Payment Offer: The offer is paid in 6 or more monthly installments over a period of up to 24 months from the offer submission date.
- Initial Payment: The taxpayer must include the first proposed monthly payment with the application. They must continue making these payments while the IRS considers the offer.
- RCP Multiplier: Use 24 months of future disposable income in the RCP calculation.
> ⚠️ Exam trap: > A common question will ask for the required initial payment for a lump-sum offer of $10,000. > > - The tempting wrong answer: $2,000 (20% of the offer). > - The complete answer: $2,205 ($2,000 initial payment + the separate $205 application fee). > - The hidden exception: If the taxpayer meets the Low-Income Certification guidelines (based on HHS Poverty Guidelines), both the $205 application fee and the initial 20% (or first periodic) payment are waived. The exam will often include income details to see if you catch this critical exception.

Worked Example: Calculating a Minimum OIC
Let's walk through a typical exam-style problem. This is how you apply the rules under pressure.
> 💡 Worked example: > Robert owes the IRS $75,000. He wants to submit an OIC based on Doubt as to Collectibility. His financial details are: > - Cash in bank: $2,500 > - Car Fair Market Value (FMV): $12,000 (Loan balance: $9,000) > - Monthly income: $4,000 > - Allowable monthly living expenses (per IRS standards): $3,700 > - The Collection Statute Expiration Date (CSED) is 60 months away. > > Robert wants to make a lump-sum cash offer. What is the minimum amount the IRS will likely accept, and what total amount must he submit with Form 656? Assume he does not qualify for the low-income waiver.
This question requires a precise, multi-step calculation.
Step 1: Calculate Net Realizable Equity in Assets
This is what the IRS could get from seizing and selling assets.- Cash: $2,500 (The full amount is included)
- Car Equity: $12,000 (FMV) - $9,000 (Loan) = $3,000
- Total Net Realizable Equity: $2,500 + $3,000 = $5,500
Step 2: Calculate Future Income Potential
This value depends on the payment option chosen. For a lump-sum offer, the IRS uses a 12-month future income calculation.- Monthly Disposable Income: $4,000 (Income) - $3,700 (Allowable Expenses) = $300
- Future Income Multiplier: 12 months (the standard for a lump-sum offer).
- Total Future Income Value: $300 x 12 = $3,600
Step 3: Determine the Minimum Offer Amount (RCP)
Combine the asset and income components to find the Reasonable Collection Potential.- RCP: $5,500 (Assets) + $3,600 (Future Income) = $9,100
- This is the minimum amount Robert must offer.
Step 4: Calculate the Required Submission Amount
For a lump-sum offer, the taxpayer must submit 20% of the offer amount plus the application fee.- Initial Payment: $9,100 x 20% = $1,820
- Application Fee: $205
- Total to Submit: $1,820 + $205 = $2,025
> ⚠️ Exam trap: > The most tempting wrong answer uses the wrong future income multiplier. Many candidates mistakenly use the full 60 months remaining on the CSED, calculating a future income value of $18,000 ($300 x 60). This leads to an inflated minimum offer of $23,500 ($5,500 + $18,000), which will certainly be a distractor choice. The distinction between the 12-month (lump-sum) and 24-month (periodic) income multipliers is a classic exam trick.
How Should You Strategize for OIC Questions on Exam Day?
To master OIC for the exam, you need to connect it to the broader practice of IRS representation.
Focus on Diagnosis, Not Just Calculation. Before you touch your calculator, ask "Why is an OIC appropriate here, and on what grounds?" The exam will test this judgment by including scenarios where an Installment Agreement is a better option, or where the client isn't in compliance and thus ineligible to even apply. Connect OIC to Broader Representation Rules. An OIC is a formal representation action. This means you must have a properly executed Power of Attorney. Understanding the complete Circular 230 rules for representation detailed in Form 2848 is critical. The exam can and will link these concepts together. Drilling these scenarios with a large question bank, like the 3,000+ questions in VoraPrep's EA course, builds the necessary pattern recognition. Final Week Review. In the week before your exam, do a quick review of the key numbers: the 2026 application fee ($205), the lump-sum initial payment (20%), and the two future income multipliers (12 and 24 months). These are easy points to grab if they are fresh in your mind.
