IRS Offer in Compromise 2026: DATC vs DATL vs ETA Explained

Daylongs · · 13 min read

Owing $60,000 to the IRS when your disposable income is $800 per month is not a math problem you can solve. An installment agreement just stretches the pain over six years while interest and penalties compound. The IRS has a statutory tool for exactly this situation: the Offer in Compromise.

An Offer in Compromise (OIC) is a formal agreement under IRC § 7122 that allows a taxpayer to settle a federal tax liability for less than the full amount owed. When accepted, the agreed amount wipes out the remaining balance permanently — no more interest, no more penalty accrual on the resolved years.

The critical qualification: OIC is not a negotiation where you propose a number you feel is fair. It is a formulaic process. The IRS will accept your offer only if it equals or exceeds your Reasonable Collection Potential — the amount the IRS could theoretically collect through forced means. Understanding how RCP is calculated is the difference between an approved OIC and a wasted filing fee.


1. The Three OIC Grounds — Which Applies to You?

OIC GroundWhen It AppliesProof RequiredForm Used
Doubt as to Collectibility (DATC)Full payment is realistically impossibleRCP < Total tax liabilityForm 433-A (OIC) or 433-B (OIC)
Doubt as to Liability (DATL)The underlying tax assessment is incorrectFactual or legal challenge to assessmentForm 656-L
Effective Tax Administration (ETA)You can pay but it would create economic hardship or exceptional circumstancesEconomic hardship or public policy groundsForm 433-A (OIC)

Doubt as to Collectibility — The Most Common Ground

This is the majority of OIC cases. The fundamental calculation is:

RCP = Net Realizable Equity in Assets + Future Income Capacity

Your offer must equal or exceed your RCP. If RCP = $12,000 and your tax liability is $95,000, an offer of $12,000 is appropriate and legally sound.

Doubt as to Liability — Challenging the Assessment Itself

DATL applies when there is a genuine dispute about whether the tax was correctly assessed — not merely that you can’t pay it. You cannot use DATL if you already filed the return in question or if a Tax Court has rendered a final decision on the liability. Common DATL scenarios: tax assessed from an audit you weren’t notified of, automatic assessments based on third-party reporting you dispute, or math errors in an IRS assessment.

Effective Tax Administration — Equity and Hardship

ETA applies where you technically could pay the full amount but doing so would create an economic hardship that offends basic equity. The IRS uses a two-part test: (1) would collection create an economic hardship, or (2) would collection undermine a compelling public policy or equity consideration. Example: a terminally ill taxpayer whose only asset is a home that must be sold to pay a tax liability, leaving no resources for end-of-life care.


2. The RCP Formula — Calculating What the IRS Thinks You Can Pay

Step 1: Net Realizable Equity (NRE) in Assets

For each asset you own, the IRS applies a discount to approximate quick-sale value:

  • Real property: Fair Market Value × 80% − outstanding mortgage balance
  • Bank accounts: Full balance (no discount)
  • Vehicles: NADA/KBB value × 80% − outstanding loan balance
  • Investment accounts (non-retirement): Current value × 80%
  • Retirement accounts (IRA, 401k): Cash-out value × 80% (accounting for early withdrawal taxes and penalties, though the IRS may apply different treatment depending on circumstances)
  • Business assets: Quick-sale value (not going-concern value)

Step 2: Future Income Capacity

This is where many taxpayers can legitimately reduce their RCP:

Monthly Disposable Income (MDI) = Monthly Gross Income − IRS-Allowable Monthly Expenses

Multiply MDI by:

  • 12 months if you pay the full offer amount within 5 months (lump-sum cash offer)
  • 24 months if you pay in 6–24 installments (deferred payment offer)

IRS National Standards — The Expense Allowance Framework

The IRS does not accept all claimed expenses. It applies standardized caps:

National Standards (uniform nationwide, household-size based): Food, clothing, personal care, housekeeping supplies. The IRS publishes current figures at irs.gov/businesses/small-businesses-self-employed/national-standards-food-clothing-and-other-items.

Local Standards (vary by county): Housing and utilities; transportation (vehicle operating costs, public transportation). Check the specific figures for your county on the IRS website.

Out-of-Standard Expenses: You may claim expenses above the standards if you have documented necessity — for example, higher-than-standard medical costs for a chronic condition. Include supporting documentation.

Critical strategic note: If your actual spending is below the IRS standard in a category, the IRS uses the lower actual amount. If it is above, the IRS uses the standard. To maximize allowed expenses and minimize RCP, claim every IRS-allowable category even if your actual spending is lower — the standard floor applies in your favor only if you claim it.


3. Form 433-A (OIC) — Individual and Self-Employed Filers

Form 433-A is the Collection Information Statement for individuals. It is the most critical document in your OIC package.

Section-by-Section Strategy

Section 1 — Personal Information Address, contact info, social security number. If you recently moved, include both addresses and explain why (IRS tracks asset movements before OIC filing).

Section 2 — Employment Information Current employer, gross and net pay, pay dates. If self-employed, monthly business income and expenses go here.

Section 3 — Other Income Include every source: rental income, Social Security, pensions, alimony received, distributions from trusts. Missing an income source is grounds for rejection.

Section 4 — Bank and Investment Accounts (Box 4.1–4.3) List all accounts with the average of the last three months’ balances. Do not use a low-balance date — IRS can subpoena bank records.

Section 5 — Available Credit Credit card limits and available balances. IRS may count available credit as an asset if you can borrow to pay the liability.

Section 6 — Real Property (Box 6.1) Fair market value documentation: recent appraisal, county assessor value, or comparative market analysis. Outstanding mortgage balance from your most recent statement.

Section 7 — Vehicles (Box 7.1–7.2) NADA or Kelley Blue Book private-party value, outstanding loan balance.

Section 8 — Business Assets (Self-Employed) Equipment, inventory, accounts receivable at net realizable value.

Section 9 — Monthly Income and Expenses The crucial comparison:

Income SourcesMonthly Amount
Wages (net)$
Self-employment (net profit)$
Other (rental, pension, etc.)$
Total Income$
Allowable ExpensesMonthly Amount
Food/clothing (National Standard)$
Housing/utilities (Local Standard)$
Vehicle operating cost (Local Standard)$
Health insurance premiums (actual)$
Out-of-pocket medical (actual vs standard)$
Court-ordered payments (child support, alimony)$
Student loans (minimum payment)$
Total Allowable Expenses$

MDI = Total Income − Total Allowable Expenses


4. Form 433-B (OIC) — Business Entities

If a corporation, partnership, or LLC owes the tax liability, Form 433-B is required instead of 433-A. If an individual is personally guaranteeing or jointly liable for a business debt, both 433-A and 433-B are submitted.

Key differences from 433-A:

  • Business assets are valued at quick-sale/liquidation value, not going-concern
  • Accounts receivable are included at collectible value (not face value)
  • The IRS evaluates whether the business is viable; a failing business with no future income may have zero future income component in RCP

5. OIC vs. Other IRS Resolution Options

OptionDebt ReductionTimelineBest For
OIC (DATC)Permanent reduction possible6–12+ monthsRCP < total liability
Installment AgreementNone — full liabilityUp to 72 monthsFull payment possible over time
Currently Not CollectibleNone — temporary pauseIndefiniteAcute financial crisis, short-term
Penalty Abatement (FTA)Penalties onlyWeeksFirst-time penalty, reasonable cause
Innocent Spouse ReliefPortion of joint liabilityVariesSeparated/divorced, spouse’s errors
Bankruptcy Ch. 7Certain old tax years dischargeableSeveral monthsBroad unsecured debt problem

OIC is optimal when your RCP is meaningfully less than your total tax debt and your financial situation is unlikely to substantially improve. If RCP is close to the total liability, an installment agreement may be more efficient.


6. Common Reasons OIC Applications Are Rejected

Incomplete financial disclosure: Missing bank accounts, unreported income streams, or failure to document asset values. The IRS cross-references W-2s, 1099s, and third-party data.

Offer below calculated RCP: The most common rejection. Recalculate RCP with the IRS pre-qualifier tool before submitting.

Unfiled tax returns: You must have filed all required returns before the IRS will process an OIC. File late returns first, even without payment.

Ongoing bankruptcy proceeding: An active bankruptcy case bars OIC consideration. Wait until discharge if possible.

Inflated expenses: Claiming expenses far above IRS standards without documentation. Back every above-standard claim with receipts and a written explanation.

Failure to make current-year estimated tax payments: The IRS expects you to stay current on obligations while the OIC is pending.


7. What Happens After You Submit: The OIC Process Timeline

Processability Check (30–45 Days)

The IRS first reviews whether your application is processable — meaning all required forms are complete, the filing fee is included (or the low-income certification is checked), all required returns are filed, and you are current on estimated tax payments if required. Applications that fail the processability check are returned unprocessed, not rejected. You may resubmit.

Assignment to an Offer Examiner

Once accepted for processing, your file is assigned to an Offer Examiner in the IRS Special Collections function. The examiner will:

  • Verify your financial information against IRS records (W-2s, 1099s, third-party reporting)
  • Request additional documentation (bank statements, mortgage statements, pay stubs)
  • May conduct an in-person interview or field visit for complex cases
  • Calculate the IRS’s own RCP figure and compare it to your offer amount

If the examiner’s RCP calculation is higher than your offer, you will receive a counter. You have the option to increase your offer, accept a rejection, or submit additional evidence to justify the lower figure.

Collection Hold During Review

While your OIC is under review, the IRS:

  • Suspends most collection activities (levies, wage garnishments)
  • Tolls the Collection Statute of Limitations (the 10-year window the IRS has to collect)
  • Does not suspend tax liens already filed — liens remain in place until the OIC is accepted and paid

This collection hold is significant. It gives you breathing room while the review proceeds, but the statute continues to toll, which can matter if you are near the end of the 10-year collection period.

If the OIC Is Accepted

Upon acceptance, you must:

  1. Pay the agreed amount within the specified timeframe (lump sum = within 5 months; periodic payment = per the schedule in your offer)
  2. File all required returns on time for the next five years
  3. Not incur a new federal tax liability during those five years

Failure to comply with these post-acceptance conditions can result in the OIC being voided, reinstating the original liability plus accrued interest.

If the OIC Is Rejected: The Appeal

You have 30 days from the rejection letter date to file a written appeal with the IRS Independent Office of Appeals. Submit Form 13711 (Request for Appeal of Offer in Compromise) with a written explanation of your disagreement with the examiner’s findings.

The Appeals officer conducts a fresh review — not just a procedural check. Appeals officers often have more flexibility than examiners and may accept offers that an examiner rejected. The success rate at Appeals for OICs is meaningfully higher than at the examiner level for well-documented cases.


8. Special Situations

Self-Employed Taxpayers and Business Owners

Self-employed filers face additional complexity because the IRS must evaluate both personal and business finances. Key points:

  • Schedule C income: Use net profit (after business expenses), not gross revenue
  • Business accounts: Included as personal assets if you are a sole proprietor
  • S-Corp or LLC pass-through: If the business is a separate entity, Form 433-B may also be required
  • Retirement accounts in the business: SEP-IRA and Solo 401k balances are included as assets

Business owners with healthy revenue but personal tax debt should document that business cash flow cannot legally be used to pay personal taxes without proper distribution procedures.

Taxpayers with Real Estate

Property is often the largest asset in the RCP calculation and the primary reason many OICs are rejected — the IRS calculates you could sell the property to pay the debt.

If the property is your primary residence and the equity is modest, the 80% discount and the requirement to leave you with sufficient income for basic expenses may result in a manageable RCP. If you own investment property with substantial equity, the OIC calculus becomes much harder.

In some cases, taxpayers successfully argue that selling a property would create an ETA hardship — particularly elderly taxpayers whose primary residence is their only asset and who have no realistic ability to rent housing at market rates.

Innocent Spouse and OIC

If you filed jointly with a spouse and only your spouse’s actions created the liability, you may have both an Innocent Spouse Relief claim (Form 8857) and an OIC option. The two can be pursued simultaneously, but an innocent spouse determination may resolve the liability without needing an OIC. Consult a licensed tax attorney about which path makes more sense for your specific situation.



Your Concrete Next Steps

  1. Use the IRS OIC Pre-Qualifier tool at irs.gov to estimate your RCP and whether OIC is viable before investing time in forms. It is free and does not notify the IRS.

  2. File all unfiled tax returns before anything else. An OIC with any missing return will be returned unprocessed.

  3. Gather financial documentation: Three months of bank statements for all accounts, current mortgage/loan statements, vehicle values from NADA or KBB, and retirement account statements.

  4. Consult a licensed tax attorney or Enrolled Agent (EA) if your situation involves business entities, international accounts, or a liability over $50,000. The RCP calculation and Form 433-A are technical enough that professional preparation materially improves acceptance odds.

  5. Verify National and Local Standards applicable to your location at irs.gov before completing your expense worksheet — these figures change annually.

What is the minimum offer amount the IRS will accept?

The IRS has no fixed minimum, but it will reject any offer below the Reasonable Collection Potential (RCP). RCP equals your net realizable equity in assets plus a multiple of your disposable monthly income. The IRS OIC Pre-Qualifier tool at irs.gov can estimate your RCP before you apply.

Does filing an OIC stop IRS collections?

Yes. When the IRS accepts your OIC for processing (not necessarily approval), it places a collection hold on levies and wage garnishments. The statute of limitations on collections is also tolled during review. If the OIC is rejected, you have 30 days to appeal before collections resume.

What is the difference between OIC Doubt as to Collectibility and Currently Not Collectible status?

CNC is temporary — the IRS pauses collection but the debt survives, continues accruing interest and penalties, and the IRS will reassess your finances periodically. OIC DATC permanently reduces the debt to what you can actually pay. If your financial situation is unlikely to improve, OIC is structurally superior.

Can I submit an OIC myself without a tax professional?

Yes. The IRS accepts pro se OIC applications. However, the RCP calculation is technical, Form 433-A is lengthy, and a single omission can result in rejection. At minimum, use the IRS Pre-Qualifier tool and review IRS Publication 594. A licensed Enrolled Agent (EA) or tax attorney typically pays for itself in higher acceptance rates.

What happens if the IRS rejects my OIC?

You receive a rejection letter with an explanation. You have 30 days to file a written appeal with the IRS Office of Appeals. The Appeals officer reviews the OIC de novo. If Appeals also rejects, you retain the option to resubmit with new financial information or pursue other resolution alternatives.
