Offer in compromise: What works, and what the IRS rejects

The offer in compromise (OIC) program gets much taxpayer attention, and not always for the right reasons. Many clients ask if they can "settle for less" with the IRS, especially after seeing ads that promise pennies-on-the-dollar relief. As a tax professional, your job is to separate myth from method and explain when an OIC is appropriate, what the IRS is looking for, and how to avoid automatic rejection.

Understand the IRS's mindset: Reasonable collection potential

The IRS uses a reasonable collection potential (RCP) formula to evaluate whether an offer is acceptable. RCP includes:

• Future income (typically 12 months for lump-sum offers, 24 months for periodic offers)
• Equity in assets (home, cars, bank accounts, cryptocurrency, retirement)
• Ability to borrow or access third-party funds

The IRS doesn't care what your client wants to pay. It cares what it could collect if it used all available tools (levies, liens and garnishment) over the life of the debt. OIC is appropriate only when the taxpayer's RCP is less than the balance due.

First step: Get compliant

The IRS won't consider an offer unless the taxpayer is fully compliant. That means:

• All required returns are filed.
• Estimated tax payments are current.
• There are no unaddressed missing years.
• Withholding is adequate to prevent future debt.

If compliance isn't met, the offer will be returned without review, and the $205 application fee will not be refunded.

Complete the right financials

Use:

• Form 433-A (OIC), Collection Information Statement for Wage Earners and Self-Employed Individuals, for individuals
• Form 433-B (OIC), Collection Information Statement for Businesses, for businesses

These are different from standard Collection Information Statements in the Form 433 series. Common mistakes include:

• Omitting assets like cash value life insurance or Venmo balances
• Reporting excessive expenses without supporting documentation
• Ignoring non-liable household income (e.g., spouse or partner)
• Claiming dependents who aren't tax dependents

Every line must be accurate and supported. Round numbers or guesswork are red flags for the IRS.

Calculate the offer

Use this formula:

(Monthly disposable income × 12) + net equity in assets = minimum offer (lump-sum)
Or
(Monthly disposable income × 24) + net equity = periodic offer

Example: If a taxpayer has $100/month in disposable income and $5,000 in equity, the minimum offer is:

(100 × 12) + 5,000 = $6,200

The IRS generally won’t accept an offer below this calculated amount unless special circumstances apply. Offering less almost always leads to rejection.

Be strategic about payment terms

The offer must include OIC payments unless the client qualifies for a low-income waiver. There are two structures:

• Lump sum: 20% of the offer upfront, remainder within five months of acceptance
• Periodic: First monthly payment submitted with the offer, continue making monthly payments during the review period

Offers can take six to 12 months to process. If the IRS accepts, the clock starts ticking for full payment. The entire offer may be revoked if the taxpayer defaults on the agreement (misses payments or fails to comply).

When OIC Is a strong option

Consider OIC when:

• The taxpayer has a low or fixed income, such as Social Security Disability Insurance (SSDI) recipients.
• There is little to no equity in assets.
• The taxpayer is near retirement, medically limited or permanently unable to work.
• The balance is large, and full payment is not possible within the CSED window.

Avoid OIC if:

• The taxpayer could pay under an installment agreement or CNC.
• They have equity in a home, crypto or retirement, and they don't want to disclose.
• The hardship is temporary, and income is expected to rebound.

What causes an offer to be rejected?

• Inflated or unsupported expenses
• Failure to disclose income streams (side jobs, cash gigs)
• Property with significant equity that isn't addressed
• Incomplete Form 433-A (OIC)
• Noncompliance with current-year tax obligations

OIC isn't a magic button; it's a data-driven, fact-based settlement negotiation. The IRS expects complete transparency.

Example: Realistic relief

Joanna owes $47,000. She is 62, earns $2,300 per month on SSDI, rents, and owns a 2008 vehicle. Her 433-A (OIC) shows $40 in monthly disposable income and no asset equity. You offer a $500 lump sum, include her waiver, and back it with 60+ pages of documentation.

Nine months later, the IRS accepts the offer. Joanna makes her final payment and is tax-debt-free for the first time in 20 years.

Delivering hope, not hype

If you offer your client a settlement option they won't qualify for, you risk damaging their trust and wasting valuable time. But when the numbers support it, an OIC can deliver a second chance. The key is understanding the standards, doing the math and documenting the story.
