Offer in Compromise Audits: Five Steps to Prepare

What an Offer in Compromise Review Means for Your Tax Debt

An offer in compromise audit is an informal description of the IRS review of an offer to settle tax debt for less than the full balance. It is not necessarily a tax-return examination. For a financial offer, file required returns, make required estimated payments, disclose assets and income, and document expenses.

The IRS does not approve an offer simply because paying is difficult. It compares your offer with what it believes it can reasonably collect from your asset equity and future income. If you challenge the amount of tax itself through a Doubt as to Liability offer, the IRS may also closely review the underlying return or assessment.

This guide covers five practical steps, from checking eligibility to responding to a returned or rejected offer. A rejection generally carries appeal rights; a returned offer generally does not.

This guide discusses how to navigate an offer in compromise audit with these 5 easy steps. Review the applicable rules and facts, and verify the qualifications and scope of any proposed representation.

Basic offer in compromise audit terms:

Understanding the Core Grounds and Mechanics of an Offer in Compromise Audit

Internal Revenue Code (IRC) Section 7122 authorizes compromises. An offer based on doubt as to collectibility generally reflects what the IRS can reasonably collect; liability disputes and effective-tax-administration offers involve different grounds. See the difference between the IRS Fresh Start Program and an Offer in Compromise and the current Form 656-B offer-in-compromise booklet.

When you submit an application, the IRS initiates an extensive examination to calculate your Reasonable Collection Potential (RCP). This investigation evaluates your net realizable equity in assets, current monthly disposable earnings, future earning capacity, and any assets placed beyond the government’s reach.

Three Qualifying OIC Categories: DATC, DATL, and ETA

The three principal grounds are described below. See also our Offer in Compromise Complete Guide:

Doubt as to Collectibility (DATC): Your assets and income are insufficient to pay the liability in full. The IRS evaluates reasonable collection potential and relevant special circumstances.
Doubt as to Liability (DATL): You establish that a genuine legal or factual dispute exists regarding whether the assessed tax debt is correct under the law.
Effective Tax Administration (ETA): You agree that the tax liability is legally accurate and that you possess sufficient assets or income to pay it in full, but full collection would create severe economic hardship or would be detrimental to public policy and equity (such as requiring the liquidation of medical funds for a severe, permanent disability).

Handling a Doubt as to Liability Offer in Compromise Audit

When filing under Doubt as to Liability using Form 656-L, the IRS process differs substantially from a typical financial collection review. Rather than examining your household budget and bank balances, the IRS conducts a targeted re-examination of the underlying tax dispute.

For a DATL offer, identify the factual or legal error and provide supporting evidence. Examples include records supporting disallowed deductions or showing that assessed income belongs to another taxpayer. Review Form 656-L eligibility and alternatives such as audit reconsideration. Related resource: IRS Audit Defense Complete Guide.

A DATL offer uses Form 656-L and does not require the financial statements, application fee or initial offer payment associated with a financial offer. A liability already finally determined by a court cannot ordinarily be challenged through this procedure.

The Impact of Open Audits and Innocent Spouse Claims on OIC Processing

An open examination or innocent-spouse claim can affect the liability and how the IRS handles an offer. Resolve these issues before submission where possible, as the current Form 656-B instructs.

Current Form 656-B advises resolving an open examination before submitting an offer. IRM 5.8.4.17.2 allows investigation to proceed in specified examination circumstances, so an open audit does not establish a categorical no-processing rule. The liability must be properly established for acceptance.

How the IRS Evaluates Ability to Pay and Allowable Living Expenses

For a financial offer, a simplified reasonable collection potential calculation combines asset equity and future income. Actual treatment depends on the applicable instructions and circumstances:

Reasonable Collection Potential (RCP) = Net Realizable Equity in Assets + (Monthly Disposable Income × Future Income Factor)

Form 433-A (OIC) generally uses 12 months of remaining monthly income for an offer paid in 5 or fewer payments within 5 months and 24 months for an offer paid in 6 to 24 months. Follow the current form and applicable exceptions.

National and Local Standards for Allowable Living Expenses

The IRS evaluates income and necessary living expenses using National and Local Standards. Different categories have different rules, and documented special circumstances can justify departures from the standards:

National Standards: Generally allow a set amount for food, clothing and other items based on household size, without requiring proof of the amount actually spent. Necessary expenses exceeding the standard may be considered when justified.
Local Standards: Housing, utilities and transportation generally use actual expenses up to the applicable allowance. Necessary expenses above the standard require justification. Use the current tables for the taxpayer’s location and household.

Expense Category	IRS Standard Rule	Allowable Deduction Metric
Food & Personal Care	National Standard	Set amount based on family size, regardless of actual spending
Housing & Utilities	Local Standard	Generally the lesser of actual spending or the local standard, subject to justified exceptions
Vehicle Operating Costs	Local Standard	Generally actual operating expenses up to the applicable standard, subject to justified exceptions
Vehicle Ownership	Local Standard	Generally actual loan or lease payments up to the allowance; no ownership allowance for a fully paid vehicle
Out-of-Pocket Healthcare	National Standard	Standard amount; substantiated necessary expenses above the standard may be allowed

Asset Equity, Dissipated Assets, and Hardship Realities

Asset equity depends on the asset, its realizable value and allowable secured debt. A quick-sale valuation may be used, but do not assume every asset receives the same discount or that every debt reduces equity. Apply the current forms and supporting documentation.

Primary Residence Equity: Home equity can affect collection potential. Document borrowing limits, health needs and other special circumstances rather than assuming paper equity guarantees rejection. See Taxpayer Advocate Service guidance on offers in compromise.
Retirement Accounts: Disclose retirement accounts and document their value, loan balances and access restrictions. Use the current Form 433-A (OIC) instructions rather than assuming every pension can be immediately withdrawn.
Transferred or Spent Assets: The IRS may examine asset transfers and the use of proceeds when evaluating collectibility. Provide records showing when assets were transferred, their value and how proceeds were used; not every expenditure is automatically added back in full.

5 Steps to Navigate an IRS Offer in Compromise Review

Properly structuring and submitting your offer requires meticulous documentation using the procedures in our Offer in Compromise Application Guide.

Step 1: Verify Strict Filing and Payment Eligibility

Before completing Form 656, check your baseline qualifications outlined in our Offer in Compromise Eligibility Guide:

Return Filing: Every required past tax return must be filed.
Estimated Tax Payments: Make all estimated-tax payments required for the current year; not every self-employed person has the same payment obligation.
Federal Tax Deposits: Business owners with employees must have deposited all required payroll withholdings for the current and prior two quarters.
No Open Bankruptcy: You cannot apply for an OIC while in an open bankruptcy proceeding. Resolve the bankruptcy status and check the current eligibility rules before applying.

Step 2: Choose Between Lump-Sum and Periodic Payment Terms

For a Form 656 financial offer, select one of two payment options. Required payments are generally nonrefundable; qualifying low-income individuals are exempt from application payments during consideration.

Lump-Sum Cash Offer: You must include a non-refundable initial payment of 20 percent of your total offered amount alongside the $205 application fee. If accepted, the remaining balance must be paid in five or fewer installments within five months of written acceptance.
Periodic Payment Offer: You must submit your first monthly installment payment with the application and continue making regular monthly payments while the IRS evaluates the offer. The total offer amount must be paid within 6 to 24 months.

Low-Income Certification Exception: Eligible individuals can use the current Form 656 household-size and location table, based on 250 percent of the applicable poverty level, and its income tests. Qualifying individuals do not submit the $205 fee, initial payment or monthly payments while the offer is considered. This does not excuse payment of an accepted offer.

Step 3: Verifying Income and Assets During an Offer in Compromise Audit

During the financial review, the IRS checks Form 433-A (OIC) or Form 433-B (OIC) and supporting records. Supply the statements, income records and asset documentation required by the current forms and any additional request; there is no single document period for every case.

Explain bank deposits and other entries that do not match reported income, with evidence of transfers, loans or other nontaxable sources where relevant. An unexplained deposit can raise questions but does not automatically establish income or require rejection. If you dispute a valuation or calculation, submit supporting evidence and ask which review or dispute-resolution procedures are available.

Step 4: Avoid Predatory OIC Mills and Unrealistic Settlement Claims

The IRS warns about offer-in-compromise promoters who promise settlements for anyone regardless of eligibility. A claim that every taxpayer can settle for pennies on the dollar is a warning sign.

Before hiring a representative, check qualifications, fees and the proposed work. Attorneys, certified public accountants and enrolled agents may have broad IRS representation rights, subject to current requirements. No representative can guarantee acceptance.

Step 5: Preserve Rights After Rejection or Return

If the IRS rejects an offer, follow the rejection letter and generally appeal within 30 days of its date, using Form 13711 or the permitted written request. A returned offer generally has no appeal right; read the return explanation and address the stated problem before resubmitting.

An administrative appeal allows review of a rejected offer under the applicable procedures. Identify disputed facts, calculations and special circumstances, and provide supporting records. See IRM 8.23.3, Evaluation of Offers in Compromise.

Furthermore, under 5.8.9 Actions on Post-Accepted Offers | Internal Revenue Service, the IRS can initiate rescission proceedings on an accepted compromise if it discovers asset concealment, fraudulent financial statements, or a mutual mistake of material fact. Maintaining an accurate evidentiary record protects your compromise from post-acceptance cancellation.

Post-Acceptance Obligations and Alternative Tax Relief Options

Post-Acceptance Compliance and Lien Release Timelines

Acceptance of an OIC is conditional upon strict five-year compliance:

Follow the accepted offer’s terms, including timely federal return filing and required payments for five years from acceptance. The exact obligations are stated in Form 656 and the acceptance documents.
Current Form 656-B describes refund offsets for applicable pre-acceptance assessed returns and specified amended-return refunds for periods ending before acceptance. Do not assume that every refund for the acceptance calendar year is retained; an offset is not an offer payment.
Failure to meet the terms may result in default and collection of the original liability, less applicable payments, with penalties and interest. Default is not necessarily instantaneous; respond promptly to any compliance notice.

Current Form 656-B states that liens for the included periods and taxes will generally be released within 45 days after the final offer payment is received and verified. Payment verification can vary; immediate release is not guaranteed.

Electronic payments: allow time for receipt and verification
Payment-method processing and verification times vary; use the current Form 656-B terms rather than a guaranteed method-specific release date.
Check payments: allow time for bank processing and verification
Payment-method processing and verification times vary; use the current Form 656-B terms rather than a guaranteed method-specific release date.
Payment-method processing and verification times vary; use the current Form 656-B terms rather than a guaranteed method-specific release date.

Exploring Partial Payment Installment Agreements (PPIAs) and CNC Status

An OIC is one possible resolution. If it is unsuitable, discuss installment payments or temporary collection relief based on your finances and the applicable requirements:

Partial Payment Installment Agreement (PPIA): A qualifying taxpayer may make payments that will not fully pay the debt before the collection period expires. The IRS reviews ability to pay and may revisit the financial information. The collection deadline can be suspended or extended by particular events; do not assume a fixed ten-year end date or automatic asset exemption.
Currently Not Collectible (CNC) Status: The IRS may temporarily suspend most collection activity if payment would prevent meeting basic living expenses. The debt remains due, interest and applicable penalties continue, refunds may be offset, and a lien may be filed. Collection can resume if finances improve.

Frequently Asked Questions About OIC Audits and Investigations

What triggers an audit or investigation after submitting an Offer in Compromise?

A financial OIC involves reviewing the information and documents supporting ability to pay. This is distinct from a new tax-return audit. A DATL offer instead addresses the validity of the liability under its separate procedure.

Can the IRS audit my accepted Offer in Compromise years later?

The IRS monitors your account for five years following acceptance. While it does not routinely audit living expenses after acceptance, it tracks your annual return filings and payments. If the IRS discovers you concealed assets or provided fraudulent income data on your original application, it can rescind the compromise under 26 CFR 301.7122-1 and reinstate the full debt.

What happens if an open IRS audit is pending when I file an OIC?

Current Form 656-B advises resolving an open examination before applying. IRM 5.8.4.17.2 nevertheless permits investigation to proceed in specified circumstances, such as certain routine examinations nearing completion. Coordinate with the IRS; any liability to be included must be properly established before acceptance.

Conclusion

A complete offer requires the correct grounds, accurate records and realistic payment terms. Review the current forms, retain copies, respond to requests and preserve any appeal deadline. Acceptance is never guaranteed.
