Is an Offer in Compromise a Good Idea?

The whole question here hinges on that single number: your RCP. Everything else — whether you have “doubt as to collectibility,” whether the settlement is “in the best interest of the government” — traces back to what the IRS believes it can realistically collect from you over the remaining collection statute. If your RCP analysis says the IRS can collect $80,000 and you owe $80,000, there is no deal to be had. If your RCP is $22,000 and you owe $80,000, there may well be.

An Offer in Compromise is authorized under IRC § 7122. It is not a discount program available to anyone who asks. The IRS processes roughly 60,000–70,000 OIC applications per year and accepts somewhere in the range of 30–40% of them. The majority of rejections come from offers that should not have been filed in the first place — either because the taxpayer’s RCP was not analyzed before filing, or because it was analyzed incorrectly.

When an Offer in Compromise Is a Good Idea

Three scenarios genuinely support filing an OIC: a doubt-as-to-collectibility case with low RCP, a doubt-as-to-liability case where the underlying assessment is disputed, and an effective tax administration case with documented exceptional circumstances. Each turns on a different factual question.

Doubt as to Collectibility — Low RCP

This is the most common basis and the one most taxpayers mean when they ask about an OIC. The standard is that the IRS cannot collect the full liability before the Collection Statute Expiration Date (CSED) under IRC § 6502 — the ten-year window from the date of assessment.

The profile that supports a strong doubt-as-to-collectibility offer: you have assets with low equity (home is underwater or nearly so, vehicle is old, retirement accounts are exempt or have negligible accessible value), your current income barely covers your allowed living expenses under the IRS Collection Financial Standards, and the balance owed is substantially higher than your RCP. When all three of those are true, an OIC is worth doing the math on.

Doubt as to Liability

A doubt-as-to-liability offer challenges the underlying assessment itself — the claim is that the IRS got the number wrong, not that the taxpayer cannot pay it. This is essentially an audit dispute packaged as an OIC, and it applies when you missed your opportunity to contest the assessment through the standard channels (IRS Appeals, Tax Court) and the statute on assessment has run. It requires a specific factual basis: new evidence, an error in the original examination, or a legal question that was not properly resolved. These offers do not require Form 433-A (OIC) because the dispute is about the amount owed, not the ability to pay.

Effective Tax Administration

Effective tax administration (ETA) offers are the narrowest category. The IRS can accept an ETA offer when collection of the full liability — even though technically possible — would create an economic hardship or would be detrimental to voluntary compliance. These are genuinely exceptional cases: a taxpayer with a serious illness who can technically pay but would be left without the resources to do so, or a situation where full collection is technically within reach but would produce a result that is clearly inequitable given the circumstances. ETA offers require the same financial disclosure as doubt-as-to-collectibility offers plus a specific narrative justification. They are not commonly accepted, but they do get approved in the right factual record.

When an Offer in Compromise Is Not a Good Idea

An OIC is not the right move when your RCP exceeds or closely approaches the balance due — the IRS will reject it, and you will lose the 20% deposit and several months off your CSED in the process.

The situations that typically produce a high RCP:

• Significant home equity. The IRS values your home at its quick-sale value — roughly 80% of fair market value — and counts the equity above the mortgage balance toward your RCP. A San Diego homeowner who bought in 2018 and has $300,000 in equity is going to have a high RCP.
• Retirement account balances. The IRS counts accessible retirement funds (IRAs, 401(k)s with early-withdrawal options) in the asset calculation, typically at face value less 30% for early withdrawal penalties and taxes. These balances substantially increase RCP even when the taxpayer has not accessed them.
• High future income. The income portion of the RCP calculation uses 12 months of future income (for a lump-sum offer) or 24 months (for a periodic payment offer), net of IRS Collection Financial Standards allowances. If your income is high enough that 12 months of allowable surplus income — what is left after the IRS’s allowed living expenses — covers a meaningful portion of the balance, the IRS’s RCP number will reflect that.
• The CSED is close to expiring. If the ten-year collection statute under IRC § 6502 has only two or three years left to run, filing an OIC tolls the CSED for the entire pendency of the offer plus 30 days. That can effectively extend the IRS’s collection window — which means you may be better off waiting out the CSED than filing an offer that will toll it and likely get rejected anyway.

That last point is one people miss. An OIC is not time-neutral. The CSED tolls from the date the IRS receives the offer through the date it is accepted, rejected, or returned, plus 30 days. A 12-month OIC process on a case with two years left on the statute adds those 12 months back to the collection window. Sometimes the right answer is to do nothing — or to use a collection alternative that does not toll the statute.

The Reasonable Collection Potential Calculation

Reasonable Collection Potential (RCP) is the IRS’s estimate of how much it can collect from you before the CSED expires, based on your assets and future income. It is calculated using Form 433-A (OIC) for individuals or Form 433-B (OIC) for businesses.

The formula has two components:

1. Asset equity at quick-sale value. The IRS takes the fair market value of your assets — real property, vehicles, bank accounts, retirement accounts, business interests, accounts receivable — and applies an 80% quick-sale factor to most categories. The result represents what the IRS believes it could realize in a forced liquidation. Equity in a primary residence is calculated as 80% of fair market value minus the mortgage balance. Retirement accounts are typically valued at 80% of the account balance, with a further reduction for applicable early withdrawal penalties.
2. Future income, net of Collection Financial Standards allowances. The IRS takes your monthly gross income, subtracts the allowable living expenses under the IRS National and Local Collection Financial Standards (housing, transportation, food, healthcare), and multiplies the net figure by either 12 months (lump-sum cash offer) or 24 months (periodic payment offer). These allowances are not your actual expenses — they are IRS-defined caps that are often lower than what you actually spend.

RCP = (asset equity at 80% quick-sale value) + (net monthly income × 12 or 24 months).

The offer amount must at least equal RCP. If it does not, the IRS is required to reject the offer.

Two things trip up most taxpayers in the RCP analysis. First, the IRS’s asset valuations are often higher than the taxpayer’s intuition — particularly for retirement accounts, business equity, and receivables. Second, the Collection Financial Standards allowances are frequently lower than a taxpayer’s actual expenses, which means the net monthly income figure the IRS uses is higher than the taxpayer expects. Both errors push the IRS’s RCP above the taxpayer’s number, and the resulting offer amount is too low to be accepted.

If you want us to run the RCP analysis before you file anything, a 15-minute call is the place to start. The analysis takes time to do correctly, but it is the only way to know whether you have a viable offer before putting money on the table.

Alternatives to an Offer in Compromise

An OIC is one of four realistic resolution paths for an IRS tax debt. The right choice depends on your RCP, your income trajectory, and how much time is left on the CSED.

Partial-Pay Installment Agreement (PPIA)

A partial-pay installment agreement under IRC § 6159 sets a monthly payment based on what you can actually afford — not the full balance amortized over time. The IRS agrees to accept a monthly payment it calculates from your disposable income, and the balance that has not been paid when the CSED expires is released. PPIAs are a useful alternative when your RCP is too high for an OIC but your monthly surplus income is genuinely low. The catch: the IRS reviews PPIAs periodically, and if your financial situation improves, the monthly payment amount can be adjusted upward.

Currently-Not-Collectible (CNC) Status

Currently-Not-Collectible status is a formal designation by the IRS that your income does not exceed your allowable expenses under the Collection Financial Standards — meaning there is nothing to collect from you right now. The IRS pauses collection activity while CNC status is in place and reviews it periodically. CNC is appropriate when your income is genuinely below the IRS’s allowable expense standards. It does not reduce the liability; it suspends collection. When the CSED expires, any remaining balance is no longer collectible.

Waiting Out the CSED

Under IRC § 6502, the IRS has ten years from the date of assessment to collect. If that window is closing and your RCP is high enough that an OIC would not be accepted, the CSED expiration itself can resolve the debt — provided you do not take actions that toll the statute further (filing bankruptcy, submitting an OIC, requesting certain collection alternatives, or living outside the U.S.). For taxpayers with large liabilities, high assets, and a CSED that expires in the next two to four years, waiting out the statute — with appropriate collection alternative protections in place to prevent levy while waiting — can be the best available path. This is a legitimate and often-overlooked strategy.

Penalty Abatement

Penalty abatement does not reduce the underlying tax liability or interest, but it can reduce the balance due by removing penalties that have accrued. First-time penalty abatement (FTA) is available under Rev. Proc. 84-35 and IRM 20.1.1 for taxpayers who have a clean compliance history. Reasonable cause abatement is available where the failure to pay was due to circumstances outside the taxpayer’s control. Penalty abatement is worth pursuing separately from — and in some cases instead of — an OIC when the penalty component represents a significant portion of the balance.

The 20% Non-Refundable Deposit Warning

Under IRC § 7122(c), a lump-sum cash offer requires a 20% non-refundable deposit of the offered amount at the time of filing. If the IRS rejects the offer, it keeps the 20%.

This matters for the decision to file. If you offer $30,000 on a $100,000 liability and the IRS rejects it because your RCP is $75,000, you are out $6,000, your CSED is shorter, and the underlying liability is unchanged. The 20% rule is not a reason to never file an OIC — it is a reason to not file an OIC without a credible RCP analysis first.

For periodic payment offers (paid in installments of six or more monthly payments), the first installment payment at filing is non-refundable in the same manner. The IRS applies both the deposit and any installment payments made during the pendency of the offer to the tax liability regardless of the outcome.

One practical note: for taxpayers who qualify as low-income under IRS guidelines (income at or below 250% of the federal poverty level), the 20% deposit and filing fee are waived. That waiver changes the cost-benefit analysis somewhat, but it does not change the underlying rule that an offer below RCP will be rejected.
