If a taxpayer cannot pay a federal tax debt in full, the two most common IRS resolution paths are an installment agreement and an offer in compromise. An installment agreement allows the taxpayer to pay the liability over time, generally in monthly payments. An offer in compromise allows the taxpayer to settle for less than the full amount owed, but only if the taxpayer qualifies under strict standards. Neither option is automatically “better.” An installment agreement is usually more available and easier to obtain. An offer in compromise can be more favorable only where the taxpayer cannot fully pay through collection or where full collection would create economic hardship or exceptional unfairness.
The short answer
For most taxpayers, an installment agreement is the more realistic option because it is designed for taxpayers who can pay over time, even if they cannot pay immediately. An offer in compromise is better only if the taxpayer can show that the IRS is unlikely to collect the full liability, that there is a genuine dispute about the liability, or that collecting in full would create economic hardship or undermine fair tax administration.
In practical terms:
- Choose an installment agreement when the taxpayer can pay the debt over time and wants a structured payment plan.
- Consider an offer in compromise when the taxpayer cannot realistically pay the full amount through available assets and future income, or where special hardship or liability issues exist.
What an installment agreement does
An installment agreement is a payment arrangement. It does not reduce the underlying tax debt. Instead, it gives the taxpayer more time to pay. IRS publications explain that the IRS bases the amount and number of installment payments on the amount owed and the taxpayer’s ability to pay within the period the IRS can legally collect. Interest and penalties continue to accrue, and there is generally a user fee to set up the agreement.
Also requires the IRS to provide independent administrative review before rejecting a proposed installment agreement or offer in compromise, and to allow an appeal to the IRS Independent Office of Appeals.
One important procedural protection is that and the related collection rules described in the sources provide that collection activity is generally restricted while certain proposals are pending and during appeal periods. IRS publications also state that the IRS generally cannot take collection action affecting property while it considers a request for an installment agreement, while the agreement is in effect, for 30 days after rejection, or while an appeal is pending.
The main advantages of an installment agreement are:
- broader availability,
- simpler qualification standards than an offer in compromise,
- ability to spread payments over time,
- no need to prove that the IRS should forgive part of the debt.
The main disadvantages are:
- full tax generally still must be paid,
- penalties and interest continue to accrue,
- user fees may apply,
- default can trigger renewed collection action.
What an offer in compromise does
An offer in compromise is fundamentally different. authorizes the Secretary to compromise civil or criminal cases arising under the internal revenue laws before referral to the Department of Justice.
For unpaid tax liabilities, the IRS recognizes three principal grounds for compromise:
- Doubt as to liability — there is a genuine dispute about whether the tax is owed or about the correct amount.
- Doubt as to collectibility — the taxpayer’s assets and income are insufficient to satisfy the full liability.
- Effective tax administration — the tax is legally owed and collectible, but collecting in full would create economic hardship or, in exceptional circumstances, would be unfair and inequitable in a way that would undermine confidence in fair tax administration.
The IRS generally will not accept an offer in compromise if the taxpayer can fully pay through an installment agreement or other means. That point is stated directly in the IRS web guidance and is consistent with the reasonable collection potential standard described in Rev. Proc. 2003-71.
For doubt as to collectibility cases, the IRS generally looks to the taxpayer’s reasonable collection potential. That includes realizable value in assets plus future income, reduced by amounts needed for reasonable basic living expenses. The IRS uses national and local allowance schedules, but requires the IRS not to apply those schedules if doing so would leave the taxpayer without adequate means to provide for basic living expenses.
Why offers in compromise are harder to get
An offer in compromise sounds better because it may reduce the debt, but it is much harder to qualify for.
Rev. Proc. 2003-71 explains that an offer based on doubt as to collectibility generally will be accepted only if it is unlikely the tax can be collected in full and the offer reasonably reflects what the IRS could otherwise collect through administrative and judicial remedies. The IRS may accept less than that amount only in special circumstances.
The IRS also verifies income and assets and generally requires detailed financial disclosures for collectibility and effective tax administration offers. Individuals generally must submit Form 433-A, and businesses generally must submit Form 433-B, with supporting documentation. By contrast, an offer based solely on doubt as to liability generally does not require a financial statement. specifically provides that for liability-only offers, the taxpayer shall not be required to provide a financial statement.
The IRS also screens offers for processability. Under Rev. Proc. 2003-71, an offer becomes pending only when the IRS accepts it for processing. If the offer is incomplete, the taxpayer is in bankruptcy, filing or payment requirements are not current, or required fees or payments are missing, the IRS may return the offer as unprocessable. A returned offer is not a rejection and generally carries no appeal right.
Up-front payments and fees matter
Imposes submission-payment rules for most offers in compromise:
- Lump-sum offers must include 20% of the offered amount. A lump-sum offer means payment in 5 or fewer installments.
- Periodic payment offers must include the first proposed installment, and the taxpayer generally must continue making installments while the offer is under review. Failure to continue those payments may be treated as withdrawal.
The taxpayer may designate how those payments are applied to assessed liabilities.
There are important exceptions. provides that the required submission payment and any user fee do not apply to certain low-income individual taxpayers whose adjusted gross income does not exceed 250% of the applicable poverty level. IRS guidance also states that no application fee is required for doubt-as-to-liability offers.
This is a major practical difference from an installment agreement. An installment agreement may involve a setup fee, but it does not require the taxpayer to make a compromise payment in order to ask for the arrangement.
Compliance requirements are critical in both programs
Both options require current compliance, but the consequences are especially important for offers in compromise.
IRS guidance states that to qualify for an offer in compromise, the taxpayer must have filed all required returns, received a bill for at least one tax debt included in the offer, made required estimated tax payments for the current year, and, if the taxpayer has employees, made required federal tax deposits for the current quarter and the two preceding quarters. The IRS may return an offer if those conditions are not met.
If the IRS accepts an offer in compromise, the taxpayer must remain compliant. IRS guidance states that for doubt as to collectibility and effective tax administration offers, the taxpayer must timely file returns and timely pay taxes for 5 years after acceptance. If the taxpayer defaults, the IRS may terminate the compromise and collect the original liability, reduced by payments made, plus interest and penalties.
Installment agreements also require ongoing compliance and payments, but they do not involve the same risk of losing a negotiated debt reduction because there was no reduction in the first place.
Appeals, review, and timing protections
Requires independent administrative review before rejection of either an offer in compromise or an installment agreement, and it gives the taxpayer the right to appeal a rejection to the IRS Independent Office of Appeals.
For offers in compromise, adds a notable timing rule: an offer submitted under is deemed accepted if the IRS does not reject it within 24 months after submission, excluding periods during which the liability is in dispute in a judicial proceeding.
That rule can be powerful, but it applies only to a submitted offer that is actually pending. Rev. Proc. 2003-71 makes clear that an offer that is returned as unprocessable was never pending for these purposes.
When an installment agreement is usually better
An installment agreement is usually the better choice when:
- the taxpayer can pay the full liability over time,
- the taxpayer wants a simpler and faster resolution path,
- the taxpayer does not want to prepare a full compromise package,
- the taxpayer is unlikely to satisfy the reasonable collection potential test for an offer,
- the taxpayer wants to avoid the risk of making nonrefundable offer payments that will simply be applied to the debt if the offer fails.
This is especially true because the IRS generally will not accept an offer in compromise if the taxpayer can fully pay through an installment agreement or other means.
When an offer in compromise is usually better
An offer in compromise is usually the better choice when:
- the taxpayer cannot fully pay through current assets and future income,
- the taxpayer has a genuine dispute about the amount legally owed,
- full collection would create economic hardship,
- exceptional equity or public policy considerations support compromise,
- the taxpayer can document the case thoroughly and remain compliant going forward.
For example, if a taxpayer’s assets and disposable income are materially below the liability, an offer based on doubt as to collectibility may produce a better overall result than years of installment payments. Likewise, if the liability itself is genuinely disputed, a doubt-as-to-liability offer may be preferable because it focuses on the correctness of the tax rather than ability to pay.
A common misconception: “better” does not mean “available”
Many taxpayers assume an offer in compromise is better simply because it may settle for less. That is too simplistic.
The IRS’s published standards show that an offer is an exception-based remedy, not the default collection solution. The IRS evaluates whether the offer reflects what it could otherwise collect and whether compromise is justified under the statutory standards. By contrast, an installment agreement is a payment mechanism for liabilities that remain fully owed.
So the better question is not “Which sounds better?” but “Which program fits the taxpayer’s facts under the IRS standards?”
