Offer in Compromise — Complete Guide

Executive Summary: The Statutory Framework of IRC § 7122

The Offer in Compromise (OIC) is a powerful administrative remedy authorized by Internal Revenue Code (IRC) § 7122, allowing the Secretary of the Treasury to compromise any civil or criminal case arising under the internal revenue laws prior to reference to the Department of Justice for prosecution or defense. For practitioners, the OIC represents the ultimate "fresh start" tool for taxpayers who are genuinely unable to satisfy their tax liabilities. However, the process is governed by strict Treasury Regulations (§ 301.7122-1) and the Internal Revenue Manual (IRM 5.8), requiring meticulous financial disclosure and a deep understanding of the IRS's valuation methodologies.

In 2026, the IRS continues to utilize the Reasonable Collection Potential (RCP) as the primary metric for evaluating offers. The RCP is a mathematical determination of the taxpayer's "ability to pay," which includes the net equity in their assets plus their future remaining income. Under IRC § 7122(d), the IRS is required to develop and publish national and local standards to ensure that taxpayers entering into a compromise have an adequate means of providing for basic living expenses. This guide provides a practitioner-grade analysis of these standards, the calculation of RCP, and the procedural requirements for a successful submission.

Key Rules and Thresholds for 2026

Tax practitioners must be aware of the specific figures and thresholds applicable for the 2026 tax year. These figures are critical for both the initial compliance check and the subsequent financial analysis:

• Standard Deduction: For 2026, the standard deduction is $30,000 for Married Filing Jointly (MFJ) and $15,000 for Single (S) filers.
• Social Security Wage Base: The 2026 wage base is $176,100, impacting the calculation of self-employment tax for business owners.
• Bonus Depreciation: Under IRC § 168(k), bonus depreciation has phased down to 60% for property placed in service in 2026.
• QBI Deduction: The Qualified Business Income deduction under IRC § 199A remains at 23% as modified by the OBBBA.
• Retirement Limits: The 401(k) contribution limit is $23,500, and the IRA contribution limit is $7,000.

Detailed Implementation Guide: Step-by-Step Instructions

Navigating an OIC requires a disciplined approach to documentation and calculation. Follow these steps to ensure a practitioner-grade submission:

Step 1: Pre-Submission Compliance Audit

Verify that the taxpayer meets the "compliance" definition under IRC § 6011 and IRC § 6654. For business owners, ensure all 941 deposits for the current and two preceding quarters are verified via the Electronic Federal Tax Payment System (EFTPS). If the taxpayer is in an active bankruptcy, the 11 U.S.C. § 362 automatic stay prevents the IRS from processing an OIC; the bankruptcy must be closed or dismissed first.

Step 2: Financial Disclosure (Form 433-A/B OIC)

The core of the OIC is the financial statement. For individuals, use Form 433-A (OIC); for businesses, use Form 433-B (OIC). You must list all assets at their Quick Sale Value (QSV), which the IRS typically defines as 80% of the Fair Market Value (FMV). IRM 5.8.5.4.1 provides that the QSV is the amount a taxpayer could realize from the sale of an asset within a short period of time, usually 90 days.

Step 3: Calculating the Reasonable Collection Potential (RCP)

The RCP is the minimum offer amount the IRS will accept. The formula is:

Step 4: Applying National and Local Standards

Under IRC § 7122(d)(2), the IRS must use "national and local standards" for living expenses. For 2026, these standards are:

Housing and transportation costs are "Local Standards" and vary by county. Practitioners must use the lesser of the actual expense or the local standard, unless a deviation is necessary for the taxpayer's health and welfare (IRM 5.15.1.7).

Advanced Practitioner Strategies: Maximizing the Probability of Acceptance

Beyond the basic RCP calculation, senior practitioners employ several advanced strategies to optimize the offer amount and navigate the IRS's internal review processes. These strategies are grounded in the Internal Revenue Manual (IRM) and relevant case law.

1. Strategic Timing of the Submission

The timing of an OIC submission can significantly impact the RCP. For instance, if a taxpayer is currently unemployed but expects to return to work in six months, filing the OIC while income is at its lowest point can result in a lower future income multiplier. However, practitioners must be wary of IRM 5.8.5.18, which allows the IRS to consider "anticipated" income if there is a clear pattern of higher earnings. Additionally, filing an OIC shortly after a significant asset transfer may trigger a "dissipated asset" investigation under Treas. Reg. § 301.7122-1(g)(4).

2. Utilizing the "Six-Year Rule" for Repayment

While the OIC is a settlement for less than the full amount, practitioners should also evaluate the "Six-Year Rule" described in IRM 5.15.1.9. This rule allows for the payment of living expenses that exceed the collection financial standards, provided the tax liability can be fully paid within six years (72 months). In some cases, an installment agreement under the Six-Year Rule may be more advantageous than an OIC, as it requires less financial substantiation and avoids the "tolling" of the statute of limitations.

3. Justifying Deviations from National and Local Standards

The IRS standards are not absolute. IRC § 7122(d)(2)(B) explicitly states that the IRS shall not use the standards if they would result in the taxpayer having inadequate means to provide for basic living expenses. Common justifications for deviations include:

• Chronic Health Conditions: Higher out-of-pocket medical costs for prescriptions, specialized care, or home health services.
• Educational Expenses: Costs for a child's special education or tuition required by a court order.
• Employment-Related Expenses: Mandatory union dues, professional licenses, or specialized tools not reimbursed by an employer.

4. Handling Business Assets and "Income-Producing" Property

For business owners filing under Form 433-B (OIC), the treatment of business assets is critical. IRM 5.8.5.5 provides that if an asset is essential to the production of income (e.g., a delivery truck for a courier service), the IRS may exclude the equity in that asset from the RCP calculation, provided the income generated by the asset is included in the future income calculation. This "double-counting" prohibition is a key protection for small business owners.

The Role of the Taxpayer Advocate Service (TAS) in OIC Cases

When an OIC is stalled or when the IRS's refusal to deviate from standards creates a genuine hardship, practitioners should consider involving the Taxpayer Advocate Service (TAS). Under IRC § 7803(c), the TAS is an independent organization within the IRS that helps taxpayers resolve problems with the IRS. A TAS advocate can issue a Taxpayer Assistance Order (TAO) if they determine the taxpayer is suffering or about to suffer a significant hardship as a result of the manner in which the internal revenue laws are being administered.

Post-Acceptance Compliance: The Five-Year Probationary Period

Acceptance of the offer is not the end of the process. The Form 656 contract includes a "compliance requirement" that lasts for five years (or until the debt is paid, whichever is longer). During this period, the taxpayer must:

• File all federal tax returns on time (including extensions).
• Pay all federal tax liabilities in full and on time.
• Failure to meet these conditions allows the IRS to terminate the compromise under IRC § 7122(e) and reinstate the original tax liability, minus any payments already made, plus all accrued interest and penalties.

Judicial Review of OIC Rejections

If the IRS Office of Appeals sustains a rejection of an OIC, the taxpayer may seek judicial review in the U.S. Tax Court. The standard of review is "abuse of discretion," as established in Murphy v. Commissioner, 125 T.C. 301 (2005). The court will determine whether the Appeals Officer's decision was arbitrary, capricious, or without sound basis in fact or law. This underscores the importance of building a comprehensive administrative record during the OIC process.

OIC for "Trust Fund" Taxes: The IRC § 6672 Nexus

One of the most complex areas of OIC practice involves payroll taxes. When a business fails to remit withheld taxes, the IRS can assess the Trust Fund Recovery Penalty (TFRP) against "responsible persons" under IRC § 6672. These individuals are personally liable for the trust fund portion of the tax. An OIC can be filed to settle this personal liability, but the IRS will often require the business to also address its portion of the debt. Practitioners must carefully coordinate the business's and the individual's OIC submissions to avoid conflicting financial disclosures.

Impact of the 2026 Tax Landscape on OIC Strategy

The 2026 tax year presents unique challenges for OIC candidates. With the Bonus Depreciation rate at 60% and the QBI Deduction at 23%, business owners may see higher taxable income than in previous years, potentially increasing their "future income" component of the RCP. Furthermore, the Social Security Wage Base of $176,100 increases the self-employment tax burden for high-earning sole proprietors. Practitioners must account for these 2026-specific factors when projecting a client's ability to pay over the 12 or 24-month multiplier period.

Step 5: Selecting the Payment Option

Taxpayers must choose between two payment tracks:

• Lump Sum Cash: Paid in 5 or fewer installments within 5 months of acceptance. Requires a 20% non-refundable down payment with the application.
• Periodic Payment: Paid over 6 to 24 months. Requires the first installment with the application and continued monthly payments while the IRS reviews the offer.

Real Numbers Example: The "Doubt as to Collectibility" Scenario

To illustrate the RCP calculation, consider a taxpayer, "Robert," a single filer residing in Los Angeles County, CA, with a total federal tax liability of $150,000 (including penalties and interest).

State Applicability and State-Specific Considerations

Acceptance of a federal OIC does not automatically settle state tax liabilities. Practitioners must navigate separate state programs, which often have different criteria and forms.

Common Mistakes and Audit Triggers

The IRS OIC unit is highly specialized and will scrutinize every line of the financial statement. Common pitfalls include:

1. Failure to Disclose Assets: The IRS uses automated data matching to identify real estate, vehicles, and business interests. Omission of an asset is grounds for immediate rejection and potential fraud investigation under IRC § 7206.
2. Dissipated Assets: Under IRM 5.8.5.18, if a taxpayer sold or transferred an asset for less than FMV in an attempt to avoid the tax debt, the IRS will "add back" the value of that asset to the RCP calculation.
3. Incorrect Expense Standards: Claiming actual expenses that exceed the local standards without providing specific "health and welfare" documentation.
4. Future Income Understatement: Failing to account for anticipated bonuses, raises, or seasonal income spikes that are evident from prior year tax transcripts.
