Comparison
Four ways a tax debt ends.
Only one of them is advertised.
Offer in Compromise, installment agreement, partial pay agreement and Currently Not Collectible, set against each other on the terms that actually decide between them.
The short answer
Which IRS payment option should I choose?
Choose an installment agreement if you can clear the balance within the remaining collection period. It is the simplest, requires no financial disclosure under $50,000, and keeps the ten-year clock running normally.
Choose a partial pay installment agreement if you can pay something monthly but not the whole balance before the statute expires. The remainder is written off at expiry, and unlike an offer it does not suspend the clock.
Choose Currently Not Collectible if payment would leave you unable to meet basic living expenses. It costs nothing, stops collection, and the statute keeps running.
Choose an Offer in Compromise only when your equity plus future income genuinely comes to less than the balance. It is the strongest outcome and the narrowest qualification, and submitting one without that arithmetic in hand extends the government's collection window for no gain.
| Installment Agreement | Partial Pay IA | Currently Not Collectible | Offer in Compromise | |
|---|---|---|---|---|
| What happens to the debt | Paid in full over time | Paid in part; balance expires with the statute | Unpaid; collection suspended | Settled for less than owed |
| Core qualification | Filing compliance and ability to pay | Disposable income insufficient to clear the balance in time | Disposable income at or below allowable living expenses | Reasonable collection potential below the balance |
| Financial disclosure | None if under $50,000 and 72 months | Form 433-A or 433-B | Form 433-A or 433-B | Form 433-A(OIC) or 433-B(OIC), fully documented |
| Upfront cost | Setup fee; reduced for direct debit, waived for low income | Setup fee | None | $205 fee plus 20% of a lump sum or the first periodic payment |
| Effect on the ten-year clock | Runs normally | Runs normally | Runs normally | Suspended while pending, plus 30 days, plus any appeal |
| Typical time to resolve | Days to weeks | 1 to 3 months | 1 to 3 months | 6 to 12 months, sometimes longer |
| Lien | Often avoidable under $25,000 with direct debit; withdrawal available | Usually filed | Usually filed | Usually filed, released on completion |
| Ongoing obligations | Pay on time, file on time, no new balances | Periodic financial review | Status reviewed as income rises | Five years of perfect filing and payment compliance |
| Failure-to-pay penalty | Halved while in force | Halved while in force | Continues to accrue | Stops on acceptance |
| Main risk | Default through a later-year balance | Payment rises if income rises | Interest keeps accruing on an unpaid balance | Rejection after the clock has been suspended |
The number that decides it
Reasonable collection potential is what the IRS believes it could collect from you over the remaining statutory period. It is your net realisable equity in assets, generally quick sale value less encumbrances, plus your monthly disposable income multiplied by twelve for a lump sum offer or twenty-four for a periodic payment offer.
Disposable income is not what is left after your actual bills. It is gross income minus allowable expenses under the national and local Collection Financial Standards. Where your housing cost exceeds the local standard for your county, the excess is generally disallowed, and the IRS treats the difference as available to pay it. This is why the person with an expensive mortgage and no savings often qualifies for less relief than they expect, and why the calculation has to be run before an application, not after a rejection.
The three mistakes that cost the most
Submitting an offer without checking the statute date
Every year of a liability has its own Collection Statute Expiration Date, visible on the account transcript. If a balance has two years left to run and you submit an offer that takes ten months to decide, you have handed the government close to a year of additional collection time. On older debts the correct advice is frequently to make no application at all.
Overlooking the partial pay agreement
It is the quiet middle option and it fits a great many people better than an offer does. Consider a $90,000 balance, $300 a month of genuine disposable income, and six years remaining on the statute. A partial pay agreement collects around $21,600 and writes off the rest, with no application fee, no twenty per cent deposit, no suspension of the clock and no five-year compliance condition afterwards.
Resolving the old debt and creating a new one
The single most common cause of default is not the payment. It is the following year's return showing a new balance because withholding or estimated payments were never adjusted. Every agreement should be set up alongside a correction to the current year, or it is being built on the thing that will break it.
Reading it against your own facts
The comparison above is genuinely usable on your own. What it cannot do is tell you your allowable expense figures, your quick sale equity, or your statute dates, and those three inputs determine the answer. Establishing them takes a Power of Attorney, a transcript pull and a few hours of analysis, and it is the work we would do before recommending any of the four.

Comparison FAQ
Questions about choosing between them.
Which option is best if I owe $80,000 and cannot pay?
It depends almost entirely on two numbers: your equity in assets and your monthly disposable income under the IRS Collection Financial Standards. With meaningful home or retirement equity, an Offer in Compromise is unlikely to be accepted and a partial pay installment agreement is usually the better route. With little equity and low disposable income, an offer may settle the balance for a fraction. With no disposable income at all, Currently Not Collectible status costs nothing and lets the ten-year clock keep running.
Does Currently Not Collectible mean the debt goes away?
Not immediately, but sometimes eventually. The balance remains and interest continues to accrue, and the IRS reviews the status as your income changes. The important feature is that the ten-year Collection Statute Expiration Date keeps running while you are in the status, so a taxpayer whose circumstances do not improve may see the liability expire without ever paying it.
Is a partial pay installment agreement better than an Offer in Compromise?
Frequently, and it is considerably less well known. A partial pay agreement collects your affordable monthly amount until the collection statute expires and writes off the rest. It costs a setup fee rather than an application fee plus twenty per cent, it does not suspend the collection clock, and it does not carry the five-year compliance condition that follows an accepted offer. On an older debt it is often the stronger option.
What happens if my Offer in Compromise is rejected?
You may appeal within thirty days, and appeals of rejected offers succeed with some regularity. The application fee and initial payment are not refunded but are applied to the balance. The real cost is time: the collection statute was suspended while the offer was pending and for thirty days after rejection, plus any appeal period, so the government has gained collection time.
